| Wkhtmltopdf - weird issue with encoding diacritics Posted: 15 Dec 2016 08:00 AM PST I downloaded official and latest version of wkhtmltopdf (0.12.4) from wkhtmltopdf.org and installed it on my Ubuntu: wget http://download.gna.org/wkhtmltopdf/0.12/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz tar xf wkhtmltox-0.12.4_linux-generic-amd64.tar.xz cp wkhtmltopdf /usr/local/bin/wkhtmltopdf
Generating a PDF I see wrong diacritics position. It's not missing, but weird render is present. See the picture (Slovak language, using UTF-8). It's happening only in Firefox (50.1.0). Safari and Chrome are OK. 
Locally on my Mac it is working fine with special characters, same as here in the browser: - Zapojenie účastníkov

Version of wkhtmltopdf is not known, I get empty response when I run: wkhtmltopdf -v

| Rails: Cannot access column from a join-table in a partial Posted: 15 Dec 2016 07:06 AM PST I want to access a column from a join-table in a partial. When I access this column in a "normal" view (e.g. fakeposts#index) it is working, however if I want to do the same in a partial, it does not work. Example: I have a users and a fakeposts table. For each user I want to display the fakeposts in a specific (randomized) order - namely based on a randomized_time column -, which is saved in a join table: randomized_posts table: user_id | fakepost_id | randomized_time
My Models look like this: #user.rb has_many :randomized_fakeposts #fakepost.rb has_many :randomized_fakeposts # randomized_fakepost.rb belongs_to :fakepost belongs_to :user
In my fakepost_controller.rb I want to get the fakeposts for the current_user and add the column "randomized_time" to my selection: My fakepost_controller.rb def index @fakeposts = Fakepost.joins(:randomized_fakeposts).where(randomized_fakeposts: {user_id: current_user.id}).select("fakeposts.*, randomized_fakeposts.randomized_time") end
This is working: index.html.erb <% @fakeposts.each do |post| %> <%= post.randomized_time %> <% end %>
This is not working: index.html.erb and my partial #index.html.erb <% @fakeposts.each do |post| %> <%= render :partial => "layouts/individual-post", :locals => {:post => post} %> <% end %> #layouts/_individual-post.html.erb <%= post.randomized_time %>
Error message => undefined method `randomized_time' for #<Fakepost:0x007f7752eeab58>
However, something like <%= post.created_at %> is working fine in my partial so I guess the way I call my partial is correct? |

| Rendering Data ServerSide with DataTables Rails Posted: 15 Dec 2016 06:52 AM PST I'm trying to eliminate rails from querying through a large dataset on the client-side. I did this using DataTables for another index I had of inventory_parts however that was using ActiveRecord Associations. For this particular use case I have a method that gets all the sales opportunities for a user, for the inventory he has in stock. It's a loop that goes through the user's parts and then checks each part against the "reverse-auction" to make sure the auction is an opportunity and if it is, stick it in this array 'sales_opportunities' So, in my Auction model I have the method: def self.get_sales_opportunities(user) parts = user.inventory_parts parts.uniq! { |part| [part[:part_num], part[:condition]] } sales_opportunities = [] parts.each do |part| #stick auction in sales opportunities #if the auction is not the user's, already contains a user bid, #or if the auction isn't asking for the part in-question's condition Auction.where(part_num: part.part_num, active: true).each do |auction| user_created_auction = (auction.company == user) user_has_placed_bids = (auction.bids & user.bids).present? part_matches = auction.condition.include?(part.condition) all_conditions = true if auction.condition[0].blank? sales_opportunities << auction unless user_created_auction || user_has_placed_bids || !part_matches sales_opportunities << auction if all_conditions && auction.company != user && !user_has_placed_bids end end sales_opportunities.uniq end
This is obviously a process and the load time is terrible.. I believe that my problem lies in the .get_sales_opportunities() mehtod, but also when trying to load server-side using DataTables my problem lies in that it expects an ActiveRecord_Associations_CollectionProxy. Here is a snippet of app/datatables/current_opportunities_datatable.rb def fetch_current_opportunities # .order does not work with an Array current_opportunities = Auction.get_sales_opportunities(@company).order("#{sort_column} #{sort_direction}") current_opportunities = current_opportunities.page(page).per_page(per_page) if params[:search].present? current_opportunities = current_opportunities.where("part_num LIKE ?", "%#{params[:search][:value]}%") end current_opportunities end . . . def sort_column columns = %w[part_num description conditions created_at elapsed_time bids lowest_bid] columns[params[:order]["0"][:column].to_i] end def sort_direction params[:order]["0"][:dir] == "desc" ? "desc" : "asc" end

| rspec mailer test with objects passed to mail method Posted: 15 Dec 2016 06:02 AM PST My rails application sends emails and the mailer methods require objects to be passed in as shown in the following code for the evidence_added_email method: class EvidenceMailer < ApplicationMailer include Rails.application.routes.url_helpers def evidence_added_email(evidence, current_user, root_url) @evidence = Evidence.find(evidence) @root_url = root_url recipients = User.where(is_auditor: true).map {|u| u.email } blind_copy_recipients = User.where(receive_notifications: true).map {|u| u.email } subject = 'SGPLAN: Evidência de ' + @evidence.milestone.manager.user_name + ' adicionada' mail(to: recipients, bcc: blind_copy_recipients, from: current_user.email, subject: subject) end def test_email mail(to: 'to@example.com', from: 'from@example.com', subject: 'Test Subject') end
The passed in evidence parameter/object requires the creation of a number of other objects. So the test spec looks like this: require 'rails_helper' RSpec.describe EvidenceMailer, type: :mailer do FactoryGirl.create(:admin_user) Agency.current = Agency.find_by(initials: 'SECTI').id FactoryGirl.create(:department) FactoryGirl.create(:first_plan) Plan.current = Plan.find_by(name: 'first').id FactoryGirl.create(:project) FactoryGirl.create(:milestone) FactoryGirl.create(:evidence) describe "evidence added email" do let(:mail) { EvidenceMailer.evidence_added_email(Evidence.find_by(name: 'Test Evidence').id, User.find_by(email: 'admin@example.com'), '/test_root_url') } it "renders the headers" do expect(mail.subject).to include("SGPLAN") end end describe "test email" do let(:mail) { EvidenceMailer.test_email } it "renders the headers" do expect(mail.subject).to eq('Test Subject') end end end
The test email example passes but the evidence added example fails with the following error: 1) EvidenceMailer evidence added email renders the headers Failure/Error: let(:mail) { EvidenceMailer.evidence_added_email(Evidence.find_by(name: 'Test Evidence').id, User.find_by(email: 'admin@example.com'), '/test_root_url') } NoMethodError: undefined method `id' for nil:NilClass # ./spec/mailers/evidence_notifications_spec.rb:14:in `block (3 levels) in <top (required)>' # ./spec/mailers/evidence_notifications_spec.rb:18:in `block (3 levels) in <top (required)>'
If I execute the spec file by stepping through it with a debugger, it appears that the describe loops are each executed twice. The first time they are executed the Evidence object and all of the other objects exist but the EvidenceMailer method is not executed. The second time the objects no longer exist but the EvidenceMailer.test_email method is executed and that test passes. I'm relatively new to rails and testing with rspec and haven't found any examples of rspec tests where parameters need to be passed into the mailer method. We're retrofitting tests to some parts of our application and I know that the evidence_added_email functionality actually works. Our environment is as follows: capybara (2.7.1) poltergeist (1.6.0) database_cleaner (1.5.3) factory_girl_rails (4.7.0) rails (4.2.5) rspec-core (3.5.4) rspec-expectations (3.5.0) rspec-mocks (3.5.0) rspec-rails (3.5.2) ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux] postgresql
Can anyone suggest how I can get this test working? |

| Overriding ApplicationRecord initialize, bad idea? Posted: 15 Dec 2016 06:35 AM PST I am creating a foo obeject like this: @foo = Foo.new(foo_params) @foo.bar = Bar.where(name: "baz").first_or_create
But there are other objects that I will need to do this as well. So, I thought of overriding the Foo initialize method to do something like this: class Foo < ApplicationRecord def initialize(*args, BarName) @foo = super @foo.bar = Bar.where(name: BarName).first_or_create end end
and call it like this: @foo = Foo.new(foo_params, "baz")
But Foo is an ApplicationRecord and it seems that it's not recommended to override the ApplicationRecord initialize method. So how could I do this? Any other ideas? Would this initialize overriding thing work? |

| Can't suspend Rails 'net/http' http request when remote IP is not avaiable Posted: 15 Dec 2016 05:09 AM PST I have an application that makes an http request to another server instance, like this: http = Net::HTTP.new(ip_address, port) Net::HTTP::Post.new("/insert", 'Content-Type' => 'application/json') request.body(data) response = http.request(request) logger.info response
It is supposed to communicate with another AWS internal instance of mine. It is working well and when the requested IP is not avaiable IT DOES timeout, like expected. The problem is when I'm running this code on my local machine. My computer can't access this IP address, so I expected it to timeout or even raise an exception, but instead of this the program blocks completely trying to do the request and I can't even stop the server (the only way was by killing the process)!

| Rails 5 sanitize vs strip_tags behavior Posted: 15 Dec 2016 04:10 AM PST I'm using Rails 5 and (using the Rails console), typed this: helper.sanitize("<p>Hi</p>") => "<p>Hi</p>"
However when I type: helper.strip_tags("<p>Hi</p>") => "Hi"
I took a look at the Rails source for strip_tags: def strip_tags(html) self.class.full_sanitizer.sanitize(html, encode_special_chars: false) end
which should use helper.sanitize (what I used at the beginning) in the background. Yet, this doesn't appear to be so, because I'm getting different output from both methods. I'm pretty sure there's some Rails magic going on in the background, just I'm not sure why. I know that if I pass some random tag in sanitize: helper.sanitize("<p>Hi</p>", tags: ['a']) #=> "Hi"
I get the desired result. So, does sanitize implicitly keeps some list of white-listed tags by default? This seems to be the only explanation I can come up with... |
| unable to insert data using custom action by belongs with has many relationship rails Posted: 15 Dec 2016 05:58 AM PST My relationships are: class PrivateClass < ActiveRecord::Base has_many :lesson_plans end class LessonPlan < ActiveRecord::Base belongs_to :private_class end
My form is like: <%= form_tag (add_lesson_plan_teacher_teacher_private_school_private_class_path), remote: true do %> <div class="row"> <div class="col-sm-6"> <div class="form-group"> <%= label_tag :title, nil, :class => "control-label" %> <%= text_field_tag "private_class[lesson_plan][title]", "", class: "form-control first_input", required: true, style: "width: 210%;" %> </div> <div class="form-group"> <%= label_tag :description, nil, :class => "control-label" %> <%= text_area_tag "private_class[lesson_plan][description]", "", placeholder: "Enter Description Here", class: "form-control", rows: "3", required: true, style: "width: 210%;" %> </div> <div class="form-group"> <%= label_tag :notes, nil, :class => "control-label" %> <%= text_area_tag "private_class[lesson_plan][notes]", "", placeholder: "Enter Notes Here", class: "form-control", rows: "3", required: true, style: "width: 210%;" %> </div> <div class="form-group"> <%= submit_tag "Create lesson plan", :class => "btn btn-info" %> </div> </div> </div> <% end %>
My controller: class Teacher::PrivateClassesController < ApplicationController before_action :authenticate_user! before_action :set_teacher before_action :set_private_school before_action :set_private_class def add_lesson_plan @lesson_plan = @private_class.lesson_plans.new(private_class_params).save end private def private_class_params params.require(:private_class).permit! end def set_teacher @teacher = Teacher.friendly.find(params[:teacher_id]) end def set_private_school @private_school = PrivateSchool.friendly.find(params[:private_school_id]) end def set_private_class @private_class = PrivateClass.find(params[:id]) end end
routes are: resources :private_schools do resources :private_classes do member do get :lesson_plan post :lesson_plan post :add_lesson_plan end end end
Now the problem is that when I try to insert data in lesson plans table it says: ActiveRecord::UnknownAttributeError (unknown attribute 'lesson_plan' for LessonPlan.): app/controllers/teacher/private_classes_controller.rb:11:in `add_lesson_plan'
What I need to do is enter the lesson plan fields data into lesson plan table with private_class_id If anything wrong please correct me. UPDATE here are the results of puts statement: def add_lesson_plan puts params.inspect, '++++++++++++++++++++++++' puts @private_class.lesson_plans.new.inspect, '**************************************' @lesson_plan = @private_class.lesson_plans.new(private_class_params).save! end {"utf8"=>"✓", "private_class"=>{"lesson_plans"=>{"title"=>"ggd", "description"=>"gghh", "notes"=>"gggkd"}}, "commit"=>"Create lesson plan", "controller"=>"teacher/private_classes", "action"=>"add_lesson_plan", "teacher_id"=>"carmel-cynthia", "private_school_id"=>"dr-jasmine-e-mcnair-high-school", "id"=>"1"} ++++++++++++++++++++++++ #<LessonPlan id: nil, title: nil, description: nil, notes: nil, subject_id: nil, teacher_id: nil, created_at: nil, updated_at: nil, is_private: true, is_publish: false, user_id: nil, publish_date: nil, popularity_count: 0, is_special: false, private_class_id: 1> **************************************

| Editing multiple images in activeadmin Posted: 15 Dec 2016 04:04 AM PST In activeadmin I can create a gallery with multiple photos. I do it with carrierwave. But I have a problem while editing the gallery. I can add photos to gallery, but I can't change existing photo and delete specific photo. My code is: schema.rb:
create_table "galleries", force: :cascade do |t| t.string "title" t.integer "admin_user_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.string "photo", default: [], array: true end
admin/gallery.rb:
ActiveAdmin.register Gallery do permit_params :title, :admin_user_id, photo: [] form partial: 'form' controller do def create @gallery = Gallery.new(permitted_params[:gallery]) @gallery.admin_user_id = current_admin_user.id if @gallery.save redirect_to admin_gallery_path(@gallery) else render 'new', notice: 'Something went wrong.' end end def update photo = params[:gallery][:photo] title = params[:gallery][:title] admin_user_id = params[:gallery][:admin_user_id] @gallery = Gallery.find(params[:id]) @gallery.title = title if title.present? @gallery.admin_user_id = admin_user_id if admin_user_id.present? if photo.present? @gallery.photo += photo elsif photo.nil? @gallery.photo = [] else end @gallery.save redirect_to admin_gallery_path(@gallery) end end index do column :id column 'Назва', :title column 'Фото' do |gallery| ul do gallery.photo.each do |photo| li do image_tag(photo.url(:medium)) if photo.present? end end end end column :admin_user_id actions end show do attributes_table do row :id row :title row :photo do ul do gallery.photo.each do |photo| li do image_tag(photo.url(:medium)) if photo.present? end end end end row :admin_user_id end end end
form partial:
<% if controller.action_name == 'new' %> <%= semantic_form_for [:admin, @gallery], html: {multipart: true}, builder: ActiveAdmin::FormBuilder do |f| %> <%= f.semantic_errors :state %> <%= f.inputs do %> <%= f.input :title, label: 'Title' %> <div class="photo-inputs"> <legend class="label"><label>Photo</label></legend> <p> <input type="file" name="gallery[photo][]" class="gallery-photo"><br><br> </p> </div> <br> <%= link_to 'Add photo', '#', class: 'add_another_photo_btn' %> <%= f.input :admin_user_id, as: :hidden %> <% end %> <%= f.actions %> <% end %> <% else %> <%= semantic_form_for [:admin, @gallery], html: {multipart: true}, builder: ActiveAdmin::FormBuilder do |f| %> <%= f.semantic_errors :state %> <%= f.inputs 'Gallery' do %> <%= f.input :title %> <%= f.input :admin_user_id, as: :select, collection: AdminUser.all.collect {|admin_user| [admin_user.name, admin_user.id] } %> <div class="photo-inputs"> <p> <%= f.inputs 'Photo' do %> <% f.object.photo.each do |image| %> <%= f.input :photo, as: :file, hint: image_tag(image.url(:thumb)), input_html: { multiple: true, value: image } if image.present? %> <br> <%= f.input :photo_cache, as: :hidden %> <% end %> <% end %> </p> </div> <%= link_to 'Add photo', '#', class: 'add_another_photo_btn' %> <% end %> <%= f.actions %> <% end %> <% end %>
And finally, my activeadmin.js file: //= require active_admin/base function removeInput() { $('.remove-field').click(function (ee) { ee.preventDefault(); $(this).parents('p').remove(); }); } $(document).ready(function () { $('.add_another_photo_btn').click(function (e) { e.preventDefault(); $('<p><input type="file"' + 'name="gallery[photo][]' + '"' + ' ' + 'class="gallery-photo"><a href="#" class="remove-field">Delete input</a><br><br></p>').appendTo('.photo-inputs'); removeInput(); }); $('<a href="#" class="remove-existed-file">Delete file</a>').appendTo('.file.input.optional'); $('.file.input.optional input').each(function (length) { $(this).attr("id", "input" + length); }); $('.remove-existed-file').click(function (e) { e.preventDefault(); $(this).parents('li').children('input').val(''); $('<p class="info-alert">A file will be removed.</p>').appendTo($(this).parent()); $(this).remove(); }) });
In activeadmin controller's update action, I've started to implement if/else, but I think, that I'm moving in a wrong direction. Is there any good solution to this issue? Thanks in advance. |
| rspec doesn't get the right value of the instance var Posted: 15 Dec 2016 05:18 AM PST I have a controller action with some instance variables which I want to test, here is my action code: def index @users_list = get_response('accounts/by_tag/QuickcallAdmin')['users'].to_a @credit_admin = !@users_list.select{|h| h['email'] == current_user.email}.blank? @accounts_emails = Account.pluck(:email) end
and the spec code: describe 'GET #index' do login_user let(:account) {create(:account)} it 'responds with 200' do get :index, :format => :html controller.instance_variable_set(:@users_list, [{"id"=>2, "email"=>"tes1@test.com", "tenant_id"=>1,"first_name"=>"valera","last_name"=>"rotari","phone_number"=>"89439438954", "tags"=>[{"name"=>"Program", "value"=>"my_company"}, {"name"=>"ProgramAdmin", "value"=>"new_program"}, {"name"=>"ProgramAdmin", "value"=>"new_program1"}, {"name"=>"QuickcallAdmin", "value"=>"q1"}, {"name"=>"CreditAdmin", "value"=>"q1"}]}]) expect(assigns(:credit_admin)).to eql(true) expect(assigns(:accounts_emails)).to eql(["tes1@test.com"]) end end
so as you can see I try to assign some hash which I usually get from the response of the api call, and after that to see if credit_admin and account_emails vars has the right value. The problem is if I pus some puts in spec after var assignation I see my value assigned, but the test fails because credit admin variable is false and is expected as true. I got the same code and put it rails console to make a test for myself, note I use the same hash, and I have the right true value. So it seems like @users_list var is not assigned right or something like this. Also @account_email is empty array, but I have account created from factory, so it should have some value in it, seems like a common problem for both of them |
| wicked pdf gem is not generating the pdf view exactly same as html in rails? Posted: 15 Dec 2016 05:49 AM PST i am generating a pdf in my rails application. but the pdf view is not looking like an html view. in pdf view the alignment and rendering is different. dont know whats happening. in controller def show_pdf_invoice respond_to do |format| format.html format.pdf do render pdf: "show_pdf_invoice" # Excluding ".pdf" extension. end end end
and in invoises/show_pdf_invoice.html.erb <style> .invoice-box{ max-width:800px; margin:auto; padding:30px; border:1px solid #eee; box-shadow:0 0 10px rgba(0, 0, 0, .15); font-size:16px; line-height:24px; font-family:'Helvetica Neue', 'Helvetica', Helvetica, Arial, sans-serif; color:#555; } .invoice-box table{ width:100%; line-height:inherit; text-align:left; } .invoice-box table td{ padding:5px; vertical-align:top; } .invoice-box table tr td:nth-child(2){ text-align:right; } .invoice-box table tr.top table td{ padding-bottom:20px; } .invoice-box table tr.top table td.title{ font-size:45px; line-height:45px; color:#333; } .invoice-box table tr.information table td{ padding-bottom:40px; } .invoice-box table tr.heading td{ background:#eee; border-bottom:1px solid #ddd; font-weight:bold; } .invoice-box table tr.details td{ padding-bottom:20px; } .invoice-box table tr.item td{ border-bottom:1px solid #eee; } .invoice-box table tr.item.last td{ border-bottom:none; } .invoice-box table tr.total td:nth-child(2){ border-top:2px solid #eee; font-weight:bold; } @media only screen and (max-width: 600px) { .invoice-box table tr.top table td{ width:100%; display:block; text-align:center; } .invoice-box table tr.information table td{ width:100%; display:block; text-align:center; } } </style> <div class="invoice-box"> <table cellpadding="0" cellspacing="0"> <tr class="top"> <td colspan="2"> <table> <tr> <td class="title"> <!-- <img src="http://nextstepwebs.com/images/logo.png" style="width:100%; max-width:300px;"> --> <%#= wicked_pdf_image_tag("https://www.nextstepwebs.com/images/logo.png") %> <%= image_tag("https://www.nextstepwebs.com/images/logo.png") %> </td> <td> Invoice #: <%= @invoise.invoice_no %><br> Created: <%= @invoise.updated_at.strftime("%a, %d-%b-%y") %><br> Due: <%= @invoise.due_date.strftime("%a, %d-%b-%y") %> </td> </tr> </table> </td> </tr> <tr class="information"> <td colspan="2"> <table> <tr> <td> <%= @invoise.company.company_name %><br> <%#= @invoise.company.company_name%><br> <%#= @invoise.company.company_name %> </td> <td> <br> <br> </td> </tr> </table> </td> </tr> <!-- <tr class="heading"> <td> Payment Method </td> <td> Check # </td> <td> Payment Method </td> <td> Check # </td> </tr> --> <!-- <tr class="details"> <td> Check </td> <td> 1000 </td> </tr> --> <tr class="heading"> <td> Item </td> <td> Quantity </td> <td> Price </td> <td> Total </td> </tr> <% @invoise.invoice_details.each do |detail| %> <tr class="item"> <td> <%= detail.item %> </td> <td> <%= detail.quantity %> </td> <td> <%= detail.rate %> </td> <td> <%= detail.amount %> </td> </tr> <% end %> <!-- <tr class="item last"> <td> Domain name (1 year) </td> <td> $10.00 </td> </tr> --> <tr class="total"> <td></td> <td></td> <td></td> <td> Total: <%= @invoise.total_amount %> </td> </tr> </table> </div>
and in gemfile gem 'pdfkit' gem 'wicked_pdf' gem 'wkhtmltopdf-binary-edge', '~> 0.12.2.1'
and i tried rendering stylesheets with wicked_pdf_tags like this <%= wicked_pdf_stylesheet_link_tag 'base' %> <%= wicked_pdf_stylesheet_link_tag 'super_admin', media: 'all', "data-turbolinks-track" => true %> <%= wicked_pdf_javascript_include_tag 'base' %> <%= wicked_pdf_javascript_include_tag 'super_admin', "data-turbolinks-track" => true %> <%= csrf_meta_tags %>
iam getting the errors when i add above wicked_tags Sprockets::Rails::Helper::AbsoluteAssetPathError at /invoises/BRUqWOeEVNSN6GCwxQqLGg%253D%253D/show_pdf_invoice.pdf Asset names passed to helpers should not include the "/assets/" prefix. Instead of "/assets/chosen-sprite.png", use "chosen-sprite.png"
the same code is used for both html view and pdf view. html view looks nice. but pdf thats generated with the same code as html is not rendering exactly same as html view. pdf view alignment is changed.Wicked pdf gem, does not generate exact views as html(with the exact alignment)? |
