| Rails Devise disable redirect for ajax request Posted: 23 Dec 2016 07:56 AM PST I want for one of the pages of the application has the ability to partially update some user settings. Also the application already has a page to edit all settings I was faced with the fact that when I send a request for a partial update, the devise redirects me to the root, but I don`t want it. Can I somehow disable redirection for the Ajax request, and leave for a page to edit all settings? Or at least turn it off for all pages at once? |
| Rails keep form data in session using devise Posted: 23 Dec 2016 07:54 AM PST I added custom field to devise registration form : radio button and select list the problem I have is that if there is an error while validating data (for example the user wrote the password wrong) I will be redirected to registration form , the custom fields will loose the data. The example is explained in those 2 pictures : Before submitting data After submitting data Like in the two pictures the user should click again the radio button to select a value , normally it should be saved in session by devise. I found a solution in stackoverflow here but I coudn't make it work with devise I generated already devise controllers but the solution dosen't work for me. Keep form fields filled after an error (RoR) |

| Audit deep associations with Rails Audited gem Posted: 23 Dec 2016 07:06 AM PST I have the next three models: class School < ActiveRecord::Base audited has_associated_audits has_many :subjects, dependent: :destroy end class Subject < ActiveRecord::Base audited associated_with: :school has_associated_audits has_many :attachments, as: :attachable, dependent: :destroy end class Attachment < ActiveRecord::Base audited associated_with: :attachable belongs_to :attachable, polymorphic: true end
Basically, A school has many subjects, and each subject has many attachments (the attachment model is polymorphic because it's used for other models too, just in case it matters...) The problem is that the audit is not working as I expect. I create a school, then a subject for that school, and then I add attachments to that subject. This is what I get from the console: School.last.associated_audits # => returns only changes on Subjects, not on subject's attachments. Subject.last.associated_audits # => returns only changes associated to its attachments
But I would need is School.last.associated_audits to include attachments audited changes too. Any ideas? |
| Like button likes all posts Posted: 23 Dec 2016 07:13 AM PST I've implemented a like/unlike function in my app. On the show page for an item, you can like/unlike without any issues. On a user's profile page though, where it lists all the foods they've uploaded, I have two issues: First, when I click the like button for one food, it triggers it for every food and then the button text under every food says "unlike this food", instead of only having the button text change for just the food that was clicked on. The like gets saved to the db for the correct food, but obviously I don't want the button text to change for foods that I haven't liked. Second, when I try to like a different food on the page without refreshing, the liked gets saved in the db as the original food that I clicked on, instead of the one I actually clicked on. users.show.html.erb <% @user.foods.each do |food| %> <div class="row col-md-12"> <div class="food col-md-4"> <h3 class="title"><%= link_to food.title.capitalize, food_path(food.id) %></h3> <%= link_to (image_tag (food.image.url)), food_path(food.id) %> <%= render 'shared/vote_form', :food => food %> <%= link_to pluralize(food.votes.count, "person"), user_votes_path(:user_id => current_user.id, :food_id => food.id) %> <%= food.votes.count == 1 ?

| Rails Mysql View to multi tables and search Posted: 23 Dec 2016 07:49 AM PST I am looking for a way to create database view to multiple mysql tables. I did not find any way to generate a model with rails. This will be used for searching multiple tables and display the result in a listbox. No update or delete or other function is needed. My understanding is to create the view directly with mysql. Than generate an empty model with rails. But is there another possibility? Situation: Class Dbtabelle1 < ActiveRecord::Base end
This one has the following db-fields: id, fldname, fldtext, fld_fld1, fld_fld2 Class Dbtabelle2 < ActiveRecord::Base end
This one has the following db-fields: id, fldname, fldtext, fld_fld4, fld_fld5 Class Dbtabelle3 < ActiveRecord::Base end
This one has the following db-fields: id, fldname, fldtext, fld_fld3, fld_fld2 Now I want to have rails through a generator to create a VIEW (talking about database view), that contains the fields with the same name from all three tables and a field that stores the Dbtabelle-name. View should have the fields: id, fldname, fldtext, flddbtabelle flddbtabelle can be identified and populated by the first two char of the name field. That will be simple sql logic. I am looking for the creation of the view. How can I get that done all with rails? Next question is: how do I address data from a db view, that I have only an empty model for? Using Ruby 2.2.4 and Rails 4.2.7 |

| Replacing high cpu usage rake tasks with another programming language [on hold] Posted: 23 Dec 2016 05:35 AM PST I have a rails app that has several rake tasks that run every 15 minutes parsing xml files and adding data from them into the database. These take tasks can sometimes hit 80% cpu on our VPS and I was thinking that replacing them with a compiled language like rust could speed them up. I was wondering how I would go about adding in another language into a rails app im guessing the biggest problem I would have is I cant have all the model stuff from the rails application in another language. In my case I think I would only be able to do the xml parsing in a compiled language and pass the results to ruby to add into the db. Is there any way to integrate other languages into a rails app? |

| How to test pdf content generated by prawn-table Posted: 23 Dec 2016 04:03 AM PST pdf-inspector provides some useful methods for testing PDFs generated by Prawn. While testing strings is straightforward, I need a way to test that tables (generated by prawn-table) are generated correctly. For example, I'm generating a table rows = ['Name','Value'] @objects.each do |object| rows << [object.name, object.value] table(rows)
I would like to include something like the following in a test let(:object} { create :object, name: 'Object', value: 10 } let(:my_pdf) { MyPdf.new( #params ) } it { expect(PDF::Inspector::Text.analyze( my_pdf ).strings ).to include "Object 10" }
This does not work because prawn-table does not generate this as a single string, but as "Object", "10". Are there any libraries out there that people recommend for testing content generated by prawn-table. Or is there a standard way to do this? |

and {multi_match: {query: params[:q], fields: ['cardholdername']}}
It is returned an empty array if I just use certificate_order.user.first_name as parameter in multi_match fields. So there is no effect of certificate_order.user.first_name. I have googled for 3 days but I haven't found right answer. What should I do to get the value of the certificate_order.user.first_name parameter? |

Gem::Ext::BuildError: ERROR: Failed to build gem native extension. current directory: /Users/agrimm/.rbenv/versions/2.4.0-rc1/lib/ruby/gems/2.4.0/gems/json-1.8.3/ext/json/ext/generator /Users/agrimm/.rbenv/versions/2.4.0-rc1/bin/ruby -r ./siteconf20161223-91367-cql0ne.rb extconf.rb creating Makefile current directory: /Users/agrimm/.rbenv/versions/2.4.0-rc1/lib/ruby/gems/2.4.0/gems/json-1.8.3/ext/json/ext/generator make "DESTDIR=" clean current directory: /Users/agrimm/.rbenv/versions/2.4.0-rc1/lib/ruby/gems/2.4.0/gems/json-1.8.3/ext/json/ext/generator make "DESTDIR=" compiling generator.c generator.c:861:25: error: use of undeclared identifier 'rb_cFixnum' } else if (klass == rb_cFixnum) { ^ generator.c:863:25: error: use of undeclared identifier 'rb_cBignum' } else if (klass == rb_cBignum) { ^ 2 errors generated. make: *** [generator.o] Error 1 make failed, exit code 2 Gem files will remain installed in /Users/agrimm/.rbenv/versions/2.4.0-rc1/lib/ruby/gems/2.4.0/gems/json-1.8.3 for inspection.

Make sure that `gem install json -v '1.8.3'` succeeds before bundling.
which I assume is due to the unification of Fixnum and Bignum into Integer. If I add to the Gemfile a constraint that json has to be version 2.0.0, then it complains that Rails 4.2 requires json ~> 1.7, which forbids 2.0.0. Am I out of luck unless the maintainers of Rails decide to make a change to a non-5.x version of Rails, or the maintainers of the json gem decide to make a new non-2.x version of their gem? |
| How to post data from one rails app to another in rails? Posted: 23 Dec 2016 04:21 AM PST I have to post data from one rails app to another and get a response in return from the latter app to the former.Both are RESTFUL apps my api to post data from the former app is as follows class OrderApiController < ApiController def send_invoice_data response = Hash.new result = Hash.new order = Order.includes(:status, :user, payment: [:status]).where(txnid: params[:txnid]).first if order if (['Notary', 'Attestation','Franking'].include? order.service.name) no_of_copies = ((order.answers.where(question_id: [37,15]).length > 0) ? order.answers.where(question_id: [37,15]).first.body : 0).to_i else no_of_copies = ((order.answers.where(question_id: [37,15]).length > 0) ? order.answers.where(question_id: [37,15]).first.body : 0).to_i + 1 end result['order'] = { id: order.id, txnid: order.txnid, service_name: order.service.name, : : discount: order.discount || '', stamp_amount: order.stamp_amount || '', delivery_amount: order.delivery_amount || '', no_of_copies: no_of_copies } response.merge! ApiStatusList::OK response['result'] = result else response.merge! ApiStatusList::INVALID_REQUEST end render :json => response end end
The controller code for the latter app is as follows: class InvoiceApiController < ApiController def order_invoice response = Hash.new result = Hash.new debugger if params[:order] && params[:order][:txnid] @order = params[:order] @order['stamp_amount'] = params[:order][:stamp_amount] || '' @order['txnid'] = params[:order][:txnid] @order['service_name'] = params[:order][:service_name] || '' @order['payment_date'] = params[:order][:payment_date] : : @order['discount'] = params[:order][:discount] || '' @no_of_copies = params[:order][:no_of_copies] pdf = WickedPdf.new.pdf_from_string( render_to_string(template: 'invoices/generate_invoice.pdf.erb', filename: params[:order] [:txnid] + ".pdf" , type: 'application/pdf', disposition: 'attachment', print_media_type: true)) save_path = Rails.root.join('pdfs', @order['txnid'] + ".pdf") File.open(save_path, 'wb') do |file| file << pdf filename = @order['txnid'] + ".pdf" end file_name = @order['txnid'] + ".pdf" upload = Invoice.upload(save_path, file_name) response['result'] = upload response.merge! ApiStatusList::OK else response.merge! ApiStatusList::INVALID_REQUEST end render :json => response end
The second app sends the link of the pdf generated invoice as response back to the former app. The link for the later app would like this: http://192.168.0.104:3000/api/v0/generate_invoice?key=value How do I achive this. I am a rails novice quite new to RESTFUL api development as well.So please help with elaboration for the solution. |
| How to add images to a word (docx) template in rails? Posted: 23 Dec 2016 01:37 AM PST I have a docx template with header and footer and some text in it.

| create button for link_to in html erb for email Posted: 23 Dec 2016 04:41 AM PST I am generating an email from a html.erb file in my rails application for the user to confirm their email address. I am trying to make the link_to line below a green button just like I use in other emails. However it shows up as a plain text link. This is the link I am having trouble with <tr style="font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; box-sizing: border-box; font-size: 14px; margin: 0;"> <td class="content-block" style="font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; box-sizing: border-box; font-size: 14px; vertical-align: top; margin: 0; padding: 0 0 20px;" valign="top"> <%= link_to 'Confirm Email', confirmation_url(@resource, confirmation_token: @token), class: 'btn-sm-mpgreen' %> </td> </tr>
And it looks like this in the email 
This is the green button from another email I create that I want to use above also. <a href="<%= ENV['EXTERNAL_URL'] %>/#/new_match" class="btn-primary" itemprop="url" style="font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; box-sizing: border-box; font-size: 14px; color: #FFF; text-decoration: none; line-height: 2em; font-weight: bold; text-align: center; cursor: pointer; display: inline-block; border-radius: 5px; text-transform: capitalize; background-color: #13904B; margin: 10px 0; border-color: #13904B; border-style: solid; border-width: 10px 20px;">Schedule Match</a>

| sharetribe engine as a gem within Core app, loading error with gem's Rails::Application Posted: 23 Dec 2016 01:20 AM PST I'm attempting to turn sharetribe into a gem via mountable engine to extend it's functionality and add features without touching it's codebase as much as possible. https://github.com/sharetribe/sharetribe I've run through the process of creating the engine and applying sharetribe, and am running into sharetribe_engine/config/environments/common.rb:3:in `': uninitialized constant Kassi (NameError) Kassi is defined within /config and I can't determine where to specify to load it (just within test/dummy for now), if that is actually the problem. https://github.com/kylegraydev/sharetribe-gem |
| How do I sort on an association of a specific user? Posted: 23 Dec 2016 01:33 AM PST I have a Profile that can be published. A profile belongs_to :user and has_many :ratings. A User has_one :profile, and has_many :ratings. A Rating belongs_to :profile && belongs_to :user. These are the schemas for the above models: Profile.rb:
# == Schema Information # # Table name: profiles # # id :integer not null, primary key # first_name :string # last_name :string # created_at :datetime not null # updated_at :datetime not null # user_id :integer
User.rb:
# == Schema Information # # Table name: users # # id :integer not null, primary key # email :string default(""), not null # created_at :datetime not null # updated_at :datetime not null # first_name :string # last_name :string
Rating.rb
# == Schema Information # # Table name: ratings # # id :integer not null, primary key # speed :integer default(0) # passing :integer default(0) # tackling :integer default(0) # dribbling :integer default(0) # profile_id :integer # user_id :integer # created_at :datetime not null # updated_at :datetime not null #
What I want to do is to find all the profiles, ranked by 1 rating attribute....e.g. all published profiles ranked by passing (highest to lowest). I tried something like this: Profile.published.where(id: coach.ratings.order(passing: :desc).pluck(:profile_id))
But that doesn't always give me the profiles in the order I expect. So how do I do this query that allows me to get these profiles ranked by all of those ratings accordingly? Edit 1 Please Note The key thing here is that I need to find the ratings on a profile left by a specific user. In my query above, coach = User.find(7). So each User leaves a bunch of ratings on many profiles. What I want to do is filter all the profiles, that have a specific rating (say speed) and order those profiles, by the speed rating from highest to lowest (but this is user specific). |
| How to implement a shared form for edit and new for RoR application Posted: 23 Dec 2016 12:29 AM PST There are two models whose relationship is one to many. I would like to implement a shared form for new and edit action. Here are example. # Migration class CreateFoo < ActiveRecord::Migration def change create_table :Foo do |t| t.string :name ... end end end class CreateBar < ActiveRecord::Migration def change create_table :Bar do |t| t.string :name t.integer :foo_id end end # Model class Foo < ActiveRecord::Base has_many :bars end class Bar < ActiveRecord::Base belongs_to :foo end # part of shared form <%form_for @foo do |f|%> <%= f.label :name %>: <%= f.text_field :name %> # text field for name1 of Bar # text field for name2 of Bar # text field for name3 of Bar ... <%end%>
When 'new' Foo, the form supports to input multiple names of Bar; when editing Foo, the form supports to edit the existing name of Bar related to some Foo. I really appreciate that corresponding controller can be given. Thanks. |
