| Rails - has_many count on validate Posted: 05 Dec 2016 07:47 AM PST I'm doin' some validation on a parent model that save nested attributes for a child model. My parent has_many childs and my validation checks if the count of those childs is greater than 0.

| Rails Model: How to do the relation Posted: 05 Dec 2016 07:43 AM PST I would like to do an app, but I am stuck on how to design the model. I have these models so far: User, Post, Tag, Like, Comment. I created for each a model, controller, view and migration file. So far so good, BUT now my question is should I just do the relations between them or create these models too: PostTag, PostLike, PostComment. You know, they would just have the relation between those, so when somebody deletes a tag in a post, he actually just deletes the relation and not the tag itself because the tag is maybe used in another post. |

| How to filter in Rails the records of table using last part of a string IN an Array of values Posted: 05 Dec 2016 07:57 AM PST Here is what I have build in the model class class Organization < ApplicationRecord ... scope :filter_by_domestic, ->(host_name_designation) do joins("LEFT JOIN events ON events.organization_id = organizations.id"). where(events: { host_name: host_name_designation }) end end
I am getting correct results when I am using something like this: @organizations = Organization.filter_by_domestic ['www.abc.com', 'www.xyz.com']
But I would like to improve the query and get the results only on the last part of the host_name, something like all records for which host_name ends with the substring .com. I need to apply split('.')last for this where(events: { host_name: host_name_designation }) and I don't know the correct syntax for this. What is the correct statement here, in my case? I want to be able to write something like: scope :filter_by_domestic, ->(host_name_designation) do joins("LEFT JOIN events ON events.organization_id = organizations.id"). where(events: { '.' + host_name:.split('.').last host_name_designation }) end
I need where to return something like this: '.' + Event.first.host_name.split('.').last Event Load (0.4ms) SELECT "events".* FROM "events" ORDER BY "events"."id" ASC LIMIT $1 [["LIMIT", 1]] => ".com"
Practically I need only the last part of the host_name to be used in the where clause. I know how to build my own where clause to achieve this, but I am looking to have the query generated instead of developed. Any clue? |

| ActiveAdmin custom select filter dropdown names Posted: 05 Dec 2016 06:01 AM PST For a user model I have a filter to check the booking status of a user which is represented by an integer value (0, 1, or 2). The filter on the User ActiveAdmin index page is achieved with the following code: filter :booking_status, as: :select
However this results in the dropdown options being either 0, 1, or 2. I would prefer if I could name them myself to something like "Incomplete", "Pending", and "Confirmed" when the admin user is selecting them from the dropdown. 
Is there any way of doing this without changing how the booking_status is represented in the model? |
| Rails routing spec with mounted Sinatra application Posted: 05 Dec 2016 05:09 AM PST I'm mounting a Sinatra-based gem into my application and would like to add a routing spec that verifies that the Sinatra app is indeed mounted at the correct path. The main application should not contain any tests that are specific to the functionality of the gem because those are of course tested there. Looking at the RSpec routing matchers and the Rails routing assertions, it seems they're only capable of dealing with controllers. For now I have added a spec that just tests a POST request with be_routable but that's not really usable for all the routes because there's always danger of accidentally using some fallback route of the main application. |
| How do I effectively preload conditional associations in Rails? Posted: 05 Dec 2016 07:16 AM PST I have the following two models: class Company < ActiveRecord::Base has_many :employees # A company can have 1000's of employees. end class Employee < ActiveRecord::Base belongs_to :company end
One of my use cases looks like this In the controller: def my_action @companies = Company.where(country: 'GB').preload(:employees) @title = params[:title] # E.g. 'CTO' end
In the view: - @companies.each do |c| = c.employees.where(title: @title).first.last_name
The problem with the above is that it will create an N+1 in the view Now I could change the view to: # In the view - @companies.each do |c| = c.employees.select{|e| e.title == @title}.first.last_name
This will solve the N+1 but it will still load out potentially 1000's of employee records even though I don't need them (I only need the ones with the right title). I could solve that by: class Company < ActiveRecord::Base has_many :employees has_many :ctos, ->{ where(title: 'CTO') } end # In the controller def my_action @companies = Company.where(country: 'GB').preload(:ctos) end # In the view - @companies.each do |c| = c.ctos.first.last_name
The problem with this however is that it would require me to add associations for every single possible type on Company. So the question is, how can I solve this? |
| Rails Simple Form - Add an error not related to attribute Posted: 05 Dec 2016 05:24 AM PST I wanna do a validation that sums the values of nested fields so I make sure it's 100%. So, in my parent model, I would do the validation, and do a self.errors.add and add the error if the validation fails. The problem is, the errors.add as long as I know expects some attribute as argument, but it's not related to any attribute on my parent model, so I would like to display that message on the top of the form, for example. Any ideas of how I can do that? thank you! UPDATE: This is my parent model, where I wanna validate. The form has nested fields for :arrendamento_contrato_unidades. class ArrendamentoContrato < ApplicationRecord has_many :arrendamento_contrato_unidades, dependent: :destroy validate :check_total_percentual_credito def check_total_percentual_credito if arrendamento_contrato_unidades.sum(&:percentual_credito).to_f != 100.0 self.errors.add :base, "Tem que ser 100%" end end end
My create method, which it's the one I'm testing: def create @arrendamento_contrato = ArrendamentoContrato.new(arrendamento_contrato_params) respond_to do |format| if @arrendamento_contrato.save format.html { flash[:notice] = flash_notice redirect_to action: "index" } format.json { render json: {status: 1, redirect: arrendamento_contratos_url} } else format.html { render :new } format.json { render json: {status: 0, errors: @arrendamento_contrato.errors, status: :unprocessable_entity} } end end end
--- Also, I debugged my object.errors.full_messages on the form, and the error is there. It's only not being displayed! I guess that add errors to the base it's what I'm looking for. But now, it's not showing my message, but only that I have validation errors. My form code: = simple_form_for(@arrendamento_contrato, validate: true, html: { id:"dropzoneForm", class: "dropzone dz-clickable"}) do |f| = f.error_notification .form-inputs .row .col-md-6 = f.input :numero .col-md-6 = f.association :usina, input_html: {class: "chosen-select"} .hr-line-dashed .row .col-md-6 = f.association :esco_contrato, input_html: {class: "chosen-select"} .col-md-6 = f.association :om_contrato, input_html: {class: "chosen-select"} .hr-line-dashed .row .col-md-4 = f.input :data_inicio, as: :string, input_html: {"data-mask" => "date"} .col-md-4 = f.input :data_fim, as: :string, input_html: {"data-mask" => "date"} .col-md-4 = f.input :valor_mensal, as: :string, input_html: {"data-mask" => "decimal"} .hr-line-dashed #arrendamento_contratos_unidades - if !@arrendamento_contrato.arrendamento_contrato_unidades || @arrendamento_contrato.arrendamento_contrato_unidades.empty? h3 = I18n.t('activerecord.models.unidade_consumidora.other') i 'Aguardando ESCO... - else .row .col-md-6 label class='control-label' = I18n.t('activerecord.models.unidade_consumidora.other') .col-md-6 label class='control-label' = I18n.t('activerecord.attributes.arrendamento_contrato_unidade.percentual_credito') .hr-line-dashed .blockquote = f.simple_fields_for :arrendamento_contrato_unidades do |f| = render 'arrendamento_contrato_unidade_fields', f: f .hr-line-dashed

| Rails 5, jQuery, add event to dynamically created items Posted: 05 Dec 2016 05:01 AM PST I have my solution working, but I believe there would be a better, more elegant way. Any ideas are very welcome. The thing is that navbar dropdown menu items has icons left to it. I placed icon and item name in separate spans so I could style them separately. I also wrapped those with a div, since I need to change background color of both - icon and list item name if hovered. Navbar renders links in dropdown menu: <ul class="dropdown-menu"> <% @categories.each do |cat| %> <li> <%= link_to cat do %> <div class="main-cont"><span id="icon-cont"><i class="glyphicon glyphicon glyphicon-tag"></i></span><span id="name-cont"><%= cat[:name] %></span></div> </li> <% end %> <% end %> </ul>
jQuery to change the background: $(document).ready(function(){ $('.main-cont').on('mouseover', function(){ $(this).find('#icon-cont').css('background-color', 'yellow'); $(this).find('#name-cont').css('background-color', 'yellow'); }); $('.main-cont').on('mouseout', function(){ $(this).find('#icon-cont').css('background-color', ''); $(this).find('#name-cont').css('background-color', ''); }); });
So it does the job, but especially jQuery part is a bit clumsy (HTML is also far away from "wow"). Any ways to improve it? Thanks! |

| Rails Friendly_ID Multiple model creation with slug on same field failing Posted: 05 Dec 2016 04:45 AM PST I am running a Rails 5 application which has 2 models - a User and a Provider. I am using multiple table inheritance to show that each Provider "is a" User (via the active_record-acts_as gem). So, in effect, creating a Provider with the related fields would create a User at the same time. I wanted to implement slugging for these models, so I integrated the friendly_id gem for that purpose. Both models are slugged via a field called username. The code in question being: class User extend FriendlyId friendly_id :username, use: :slugged # ... end
for the User model and class Provider extend FriendlyId friendly_id username, use: :slugged def username acting_as.username # this fetches the parent model (User)'s username field. end # ... end
for the Provider model. When I attempt to create a Provider via a controller action (providers#create), it fails, with the error being: TypeError at /providers nil is not a symbol nor a string
The stack trace identifies the problem to be at lib/friendly_id/slugged.rb:299, which is the body of the should_generate_new_friendly_id? method. This method was called by the set_slug method in the same file, slugged.rb. I have created an issue on the GitHub page of friendly_id, where you can find the request parameters and full stack trace. Edit: added friendly_id_config for both: https://gist.github.com/mindseyeblind/9b78c588f5008a494f7157e72da1de6e |

| Rails convention for non-index integer fields Posted: 05 Dec 2016 04:59 AM PST I want to keep statistics of records (let's say books), that how many times they've displayed on a page. I've added an integer column called featured, based on that attribute, I'm fetching records which has less count of featured. This will reduce inequality and I will be happy, because I am a communist :) def foo @books = Book.order(:featured).take(5) @books.each { |book| book.update_columns(featured: book.featured+1) } render 'bar' end
Suddenly I've realized that attributes with ed suffix ( past (perfect) tense ) are generally used for boolean fields (e.g. book.published?, book.featured?, book.approved?), which is more intuitive. And if I keep featured as an integer attribute name, this may confuse other newcomers in future. So, is there a more readable convention for integer fields? |

UPDATE [SOLVED] Ok, it appears I was being blind and hadn't realised an extra set of double quotes were being generated for class="'wibble'" - thanks to @Dekel for quickly pointing that out, and allowing me to find the cause of the real issue. To solve the issue of the generation of extra quotes I had to mark the output as html_safe: <td<%= ((index == @project.active_pattern_index) ? ' class="wibble"' : '').html_safe %>> <%= pattern.row(count).instruction %> </td>

| Test controller failed: NoMethodError: undefined method `env' for nil:NilClass Posted: 05 Dec 2016 06:08 AM PST I have a problem with unit testing in ruby on rails (rails v. 5.001). The user needs to login in a test unit, but how can I implement this? Here is the code: appointments_controller_test.rb require 'test_helper' class AppointmentsControllerTest < ActionDispatch::IntegrationTest include Devise::TestHelpers setup do @heikoAppointment = appointments(:appointment_heiko) @heiko = users(:heiko) heiko = users(:heiko) end test "should get index" do get appointments_url assert_response :success end test "should get new" do sign_in @heiko get new_appointment_url assert_response :success end

Sie wurde vor den DB änderung erstellt und muss angepasst werden #D.S.:ShoppingItem.joins(:list_item) und ListItem.where(shopping_list_id: @shopping_list.id]) ergeben ein korrektes Resultat #D.S.:Aber zusammengenommen ist die query leer #@shopping_items = ShoppingItem.joins(:list_item).where(list_item: [shopping_list_id: @shopping_list.id]) end private def get_both_lists shopping_lists = [ @appointment.shopping_list] if @appointment.invitation && @appointment.invitation.shopping_list shopping_lists << @appointment.invitation.shopping_list end shopping_lists end private def get_both_users users = [ @appointment.user] if @appointment.invitation users.push(@appointment.invitation.user) end users end private # Use callbacks to share common setup or constraints between actions. def set_appointment @appointment = Appointment.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def appointment_params params.require(:appointment).permit(:shopper_id, :status, :appointed, :processed, :shopping_list_id, invitation_attributes: [:user_id, :message ]) end def create_shopping_list? if @appointment.shopping_list_id.blank? name = "Liste für den " + @appointment.appointed.strftime("%d.%m.%Y").to_s invitee_id = "" + (@appointment.invitation.user_id.to_s) if @appointment.invitation name = name + ( " mit " + User.find(invitee_id).firstname) unless invitee_id.blank? sl = current_user.shopping_lists.create(:name => name) @appointment.shopping_list_id = sl.id true else false end end end
And here is the Error I get when I run the test: Error: AppointmentsControllerTest#test_should_get_new: NoMethodError: undefined method `env' for nil:NilClass
Does somebody know the solution? I would be very thankful UPDATE: include Devise::TestHelpers is deprecated. Now I use include Devise::Test::IntegrationHelpers. Now my appointments_controller_test.rb looks like this: require 'test_helper' class AppointmentsControllerTest < ActionDispatch::IntegrationTest include Devise::Test::IntegrationHelpers def sign_in(user) post user_session_path \ "heiko@me.com" => user.email, "hhdk#s0" => user.password end setup do @heikoAppointment = appointments(:appointment_heiko) @heiko = users(:user_heiko) sign_in(@heiko) end test "should get index" do get appointments_url assert_response :success end test "should get new" do sign_in(@heiko) get new_appointment_url assert_response :success end
However I get another error: AppointmentsControllerTest#test_should_get_new [C:/Users/Clemens/meindorfladen/Server/test/controllers/appointments_controller_test.rb:33]: Expected response to be a <2XX: success>, but was a <302: Found> redirect to <http://www.example.com/users/sign_in>
Does somebody knows why there is this redirect to http://www.example.com/users/sign_in? I thought now the user is signed in |

| Converting array of objects into array of strings Posted: 05 Dec 2016 03:15 AM PST I'm working on an app where I need to pass an array of strings to a backend service something like const ids = []; for (let i = 0; i < pIds.length; i++) { ids.push(pIds[i].id); } // pIds is an array of objects [{id: 2, name: 'dd'}] this.webClient = new Frisbee({ baseURI: `${Secrets.url_host}/api/v1`, headers: { Accept: 'application/json', 'Content-Type': 'application/json', }, }); getData({ continuation = 1, q = '', ids = '' }) { return this.webClient.get('/whatever', { body: { 'platform_ids': ids, }, }).then(getContent);
} after running this code if get an array of ids [2,3] for example but when I pass it to the backend (ruby on rails ) it arrive like that [{"0"=>"1", "1"=>"2"}]
What can I do to get it as ["1", "2"]? I've tried many solutions but nothing works. |
| Rails, mapbox and geocoder : find object near another object Posted: 05 Dec 2016 04:04 AM PST I try to find an object @center near an object @school depending the location, and show the center on mapbox. I past my code here because I'm not sure of what I did : here is the code displaying map (with 2 data : school and center) : <div id="school-map" data-coordinates="<%= @school.coordinates.reverse %>" data-centers="<%= @center.coordinates.reverse %>"> </div>
here is the center.rb model : class Center include Mongoid::Document include Geocoder::Model::Mongoid has_many :schools accepts_nested_attributes_for :schools field :title, type: String field :image_path, type: String field :Attachment_path, type: String field :website, type: String field :phone, type: String field :street, type: String field :zipcode, type: String field :city, type: String field :coordinates, type: Array geocoded_by :adress #after_validation :geocode def adress [street, zipcode, city].compact.joint(', ') end end
In school.rb model, I try this method : def center_near_school(school_adress_coordinates) school_adress_coordinates = @school.coordinates.reverse center = Center.near(school_adress_coordinates, 1, units: :km)
end and I try to show string like "yes" or "no" to know if my method work : <% if @school.center_near_school %> <p> OUI </p> <% else %> <p> NON </p> <% end %>
I create relation (has_many :schools, and has_many :centers) in both models, the markers generations are created in show.js which displaying the map. Does someone could help me to find some solutions to create this functionality ? Don't hesitate to ask me to edit this post with more informations (code, precisions ...) thank ! |
