| Rails, static page for newest model Posted: 08 Apr 2016 06:51 AM PDT In my rails app I have a model called "Gamesession", this will take some variabels to generate different configurations to a game(i'm playing in real life) each time I play. So I want a static page called play.html.erb to always be the place where the newest "active" session is. Right now I'm deleting all the previous sessions everytime I make a new. So that I can use the gamsession#index. Is there a better way to only have one "active" gamesession on the same page(play.html) each time? Please explain in detail if you have the time, I'm very new at rails. Thank you! |

| Elasticsaerch rails - can't search for mac extensions Posted: 08 Apr 2016 06:33 AM PDT I have setup elastic search rails with the 'elasticsearch-model', 'elasticsearch-rails' gems. I am trying to search for these attachments by their content. It works well when I have an indexed PDF, Word, plain text, or a plefora of other formats. But it does not work when I index a mac format, e.g. .pages, .keynote and .numbers files. I made sure that mac files get indexed, but it feels like they are not indexed properly. When I look at raw index data for a .word file vs .pages file, they both have their respective attachment fields populated as base64 representation of the document content. It seems like for the mac extensions, however, this base64 representation isn't accurate. My index model definition: settings index: { number_of_shards: 3 } do mappings do indexes :filename indexes :uploaded_by indexes :project_id, index: :not_analyzed indexes :attachment, type: 'attachment' end end def as_indexed_json(options={}) self.as_json({ only: [:project_id, :filename, :uploaded_by, :attachment], methods: [:attachment] }) end
My attachment method: def attachment if url key = url.sub("https://s3.amazonaws.com/#{ENV['BUCKETNAME']}/", "") content = AWS.s3.buckets[ENV['BUCKETNAME']].objects[key].read Base64.encode64(content) end end
The file first gets uploaded to s3 (since client side sends it there directly), then read by the server from s3 to get indexed. this is a proof of concept code only, future dev will upload from client to server, index, then upload to s3, then delete from server. E.S version: "1.7.1", Lucene version: "4.10.4" |
| How to validate presense of a value based on an API call Posted: 08 Apr 2016 06:49 AM PDT I've got a model @record_request that takes in a unique identifier and saves it to the database - the model can be later used to fire a bunch of API requests off to an external database to do it's work. Thing is, I don't want the user to be able to save the value in the Rails app, if it can't be queried in the remote database. I've tried creating validations and creating Rspec tests, but all of them require my @current_user variable with all the api_token and referesh_token and other OmniAuth goodies needed to make an autenticated API call... So I'm kind of stumped. Where is the best practice place to put a validation rule of this kind. I'm thinking I'll have to put something in my controller on :create that makes the call there and raises errors/flashes that way... but then it seems like I've got a load of code on my controller, and I've fallen for a fat controller anti-pattern, no? What is the best practice? |

| Users, form and tasks association rails Posted: 08 Apr 2016 06:17 AM PDT I have an app allowing a user to fill a form (named "checklist") and then have a list of tasks he will have to do. The tasks (named "advices") are related to the answers that the user gave in the form. For example, if a question is "have you cooked dinner ?" and the user answers "no", then an advice "go cook dinner" will be displayed. Once a advice is done, the user can mark it as completed. Advices are the same for all users. They already are created in the app by admin. So users have a checklist, checklist belongs to a user. The problem I encounter is : when a user marks an advice as completed, it is marked as completed for all users. That should not be. I am not really sure how to fix this. Associations "Has-many", and "Belongs_to" between advices and users should not work since the user does not create the advices ? I am new to rails so I would be happy if someone could help. Note that I use Devise to manage users.

| Unable to render inline attachments in ActionMailer Posted: 08 Apr 2016 06:34 AM PDT I'm trying to render inline images in a standard ActionMailer view using the approach outlined here Rails attachments inline are not shown correctly in gmail. My code in my mailer: attachments.inline["sample.png"] = { mime_type: "image/png", encoding: "base64", # Including this line causes byte sequence error data: File.read('public/sample.png') }
In mail view: image_tag(attachments["sample.png"].url)
Gives the familiar ruby UTF-8 byte sequence error: invalid byte sequence in UTF-8
To get around this I tried the following: attachments.inline["logo.png"] = { mime_type: "image/png", data: Base64.encode64(File.read('public/logo.png')) }
and also attachments.inline["logo.png"] = File.read('public/logo.png')
Using the same image_tag syntax shown above. Both of these resolve the UTF error, but I'm left with this nonsensical URL in the view: <img src="cid:5707a64ededbc_7bd83ffd648601e029875@localhostname.mail">
The PNG image is valid and renders properly in a standard HTML view. I'm using Rails 4.2.5 with Ruby 2.2.4 EDIT This works: Mailer: attachments.inline["cape.png"] = { mime_type: "image/png", # encoding: "base64", content: Base64.encode64(File.read(Rails.root.join("public/", "cape.png"))) }
View: = image_tag "data:image/png;base64,#{attachments['logo.png'].read}"
Very awkward, however, and I'm still wondering why the conventional approach doesn't work. |

| Rails: how to retrieve the params for child objects in nested form Posted: 08 Apr 2016 05:37 AM PDT I have a wizard situation where I create a Parent object, and then build a form with 2 nested children. The parameters that get submitted look like this: Parameters: {"room"=> {"parents_attributes"=> {"0"=>{"name"=>"r2", "phone"=>"07443107986"}, "1"=>{"name"=>"", "phone"=>""}}}, "commit"=>"Go!", "id"=>"step03"}
(the commit and id are from the wicked wizard step) If the user refreshes the page, the id's for these children change and the parameters look like this: Parameters: {"room"=> {"parents_attributes"=> {"1"=>{"name"=>"r2", "phone"=>"07443107986"}, "2"=>{"name"=>"", "phone"=>""}}}, "commit"=>"Go!", "id"=>"step03"}
Since the id's are generated by the fields_for. My controller code retrieves the data like this (the room is saved in the session on a previous step): @room = Room.find(session[:room_id]) @room.parents.build(room_params[:parents_attributes]['0']) @room.parents.build(room_params[:parents_attributes]['1'])
This obviously only works if the user does not refresh the page. Also, if validations fire the id's of the children change too. What is a better way to retrieve these parent_attributes from the params hash? EDIT In the wizard step, the child objects are built like this: when :step03 @room = Room.find(session[:room_id]) 2.times{ @room.parents.build }

This code generates perfect form but in this form dropdown generated has cached values. That is if we modify name of any Abc record, its change is not reflected in the form even after refreshing the page. Form has following options <option value="6">Bla</option> <option value="7">Alliance</option>
After editing value Bla to Foo in DB our form still shows same old result. Though value in db has been changed. After editing records. Though Bla should be changed to Foo now <option value="6">Bla</option> <option value="7">Alliance</option>

| Select2 with ajax gets initialized several times with Rails turbolinks events Posted: 08 Apr 2016 03:49 AM PDT I am a developing a Ruby On Rails app using Rails 4.2.6. I am using Turbolinks alongside jquery.turbolinks (sorry I could'nt post the links to those elements as I am a newbie on the site). My problem is very simple but I just can't solve it. Here it is: I have a form fetched through AJAX <div class="card-footer"> <a class="btn btn-sm btn-primary-outline" data-remote="true" href="/profiles/Mke5kA/positions/new"><i class="fa fa-plus"></i> Nouvelle expérience professionnelle</a> <div id="new_position_form"></div> </div>
The form contains Select2 elements that get their data through AJAX = simple_form_for [profile, position], remote: true, html: {id: 'positionForm', class: 'm-b-1'} do |f| = f.input :company_id, as: :select, input_html: {:'data-behaviour' => 'company-select2', :'data-kind' => 'company'} = f.input :title = f.input :summary - location = f.object.build_location = f.simple_fields_for :location do |l| = render 'locations/fields', l: l, city: position.city = render "profiles/shared/date_fields", f: f, model: position = f.input :skill_list, as: :select, input_html: {multiple: true, :data => {:behaviour => 'acts-as-taggable', :'taggable-context' => 'skills'}} %button.btn.btn-primary{:type => "submit"}= icon('check-square-o', 'Enregistrer') = link_to icon('remove', 'Annuler'), 'javascript:void(0)', data: {:'lgnk-behaviour' => "remove-form", :'lgnk-target' => "#positionForm" }, class: 'btn btn-secondary'
- The Select2 elements are "activated" currently upon Rails Trubolinks events "page:load page:update", but I have also tried "page:change"
- When the form is fetched: the select2 elements are fine (activated correctly):
My problem appears when I try typing in the Select2 that are using AJAX to get the data: all the select2s are duplicated: 
Here is how I get the Select2 initialized: var loc_tag = function() { $('[data-behaviour="acts-as-taggable"]').not('.select2-hidden-accessible').each (function (index, element) { if ($(element).data('value')) { var options = $(element).data('value').split(', '); $.each(options, function(key, tag){ $(element).append($('<option selected></option>').val(tag).text(tag)); }); } $(element).select2({ ajax: { url: "/tags?context="+$(element).data('taggable-context'), dataType: 'json', headers: { "Accept": "application/json" }, delay: 250, data: function (params) { return { q: params.term, // search term page: params.page }; }, processResults: function (data, page) { return { results: data }; }, cache: true }, escapeMarkup: function (markup) { return markup; }, // let our custom formatter work minimumInputLength: 2, tags: true, language: "fr", theme: "bootstrap", width: "100%", placeholder: 'Mots clés...' }); }); }; $(document).on('page:load page:update', loc_tag);
I want the Select2 elements to get initialized only once (when the form is fetched) and not upon AJAX responses on them getting their data. I have tried jQuery.not(".select2-hiden-accessible") on the elements unsing Select2 (select2-hidden-accessible being the class Select2 adds to an initialized Select2 element) but it does not work. Many thanks for your kind help! |
| Rails query param in URL twice Posted: 08 Apr 2016 04:26 AM PDT I have a search form that searches a geocoded model called property. The geocode search works fine. However when I introduce more params to the search it returns incorrect results. I have two boolean columns on the property model, smokers and pets. In my URL I notice that the same query param for pets is inserted twice: http://localhost:3000/properties?utf8=%E2%9C%93&location=L17+6DD&distance=10&pets=false&pets=true&smokers=false&commit=Search I'm using Rails 4.2.6, Ruby 2.3.0 and PostgreSQL Search form: <%= form_tag properties_path, method: :get do %> <%= label :location, "Search properties near : " %> <%= text_field_tag :location, params[:location] %> <%= label :distance, "Distance : " %> <%= text_field_tag :distance, params[:distance] %> <%= label :pets, "Pets : " %> <%=hidden_field_tag 'pets', false%> <%=check_box_tag 'pets', true %> <%= label :smokers, "Smokers : " %> <%=hidden_field_tag 'smokers', false%> <%=check_box_tag 'smokers', true %> <%= submit_tag "Search" %> <% end %>
Properties controller action: def index if params[:location].present? @properties = Property.near(params[:location], params[:distance] || 10) .where("pets = :pets", {pets: params[:pets]}) .where("smokers = :smokers", {smokers: params[:smokers]}) else @properties = Property.all end

| Location model as polymorphic association Posted: 08 Apr 2016 04:07 AM PDT I hope I'm forming this question correctly. But I'm trying to create a location model that has a geocoded address and that address is able to be located on a map using gmap for rails. My issue is associating my Location model with other application models. Currently I'm attempting to have a location field within my post form. My application is as followed using the geocoder and gmaps for rails gems. class Location < ActiveRecord::Base belongs_to :locatable, polymorphic: true belongs_to :post geocoded_by :address acts_as_gmappable after_validation :geocode validates :address, presence: true validates :latitude, presence: true validates :longitude, presence: true def gmaps4rails_address "#{address}" end validates :locatable, presence: true end
Post model class Post < ActiveRecord::Base has_one :location, as: :locatable , :dependent => :destroy accepts_nested_attributes_for :locations,:reject_if =>:all_blank ,allow_destroy: true end
Controllers Post Controller def new @post= current_user.posts.build end def create @post = current_user.posts.new(post_params) @post = Location.new if @post.save redirect_to root_path else render 'new' flash[:error] = !" end end def post_params params.require(:post).permit(locations_attributes[:address,:latitude,:longitude, :locatable_id, :locatable_type, :gmaps]) end
Locations Controller class LocationsController < ApplicationController def new @location = Location.new end def create @location = Location.new(params[:location]) end def destroy @location.destroy respond_to do |format| format.html { redirect_to locations_url, notice: 'Location was successfully destroyed.' } format.json { head :no_content } end end private def location_params params.require(:location).permit(:address, :latitude, :longitude, :locatable_id, :locatable_type, :gmaps) end end
My code might be snippet out but my overall issue is happening within the controller I have everything going right. The location field within my post form is a nested form of the model location, the address field is geocoded and has a location search for the address input. My problem arises when submitting the post, I've tried several methods but I cannot get the location to save to post model. Any help would be amazingly helpful. |
| Rspec & ShouldaMatchers with class_name Posted: 08 Apr 2016 03:35 AM PDT I'm getting following error: 1) Admin should belong to hospital Failure/Error: it {should belong_to(:hospital).with_foreign_key('medical_facility_id') } Expected Admin to have a belongs_to association called hospital ()
with: #admin_spec.rb it {should belong_to(:hospital).with_foreign_key('medical_facility_id') }
Models are: class Admin < ActiveRecord::Base belongs_to :hospital end class Hospital < MedicalFacility end
In schema.rb: create_table "admins", force: :cascade do |t| t.integer "user_id", null: false t.string "role", null: false t.integer "medical_facility_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false end
How to correctly write test for this model? Maybe I should add `class_name:"MedicalFacility" to the Admin model? |
| Large number of threads under unicorn Posted: 08 Apr 2016 03:28 AM PDT I am in the process of debugging some Posgtres connection leaks in our application. Few days back we suddenly crossed 100 connections when we should not be - coz we just have 8 unicorn workers and a sidekiq process (25 threads). I was looking at htop today and saw that a ton of threads were being spawned from my unicorn workers. Eg:  Am I reading this correctly? This should not be happening right? If these are threads being spawned, any idea how to debug this?
Thanks! Btw, my other problem - (Postgres connections) Debugging unicorn postgres connection leak |
