| Ruby on Rails - Create a form with Multiple instances of the same model Posted: 25 Jul 2016 08:15 AM PDT I have a model, namely "bank_accounts", which contains many users I want to use a form to list out all users (while the first name is editable), so that one click of "submit" can gather all users' first name. -@bank_accounts.each do |account| =form_for account do |f| =f.text_field :first_name
The code above gives something like <form class="edit_bank_accounts" id="edit_bank_account_1" action="/bank_account/1" accept-charset="UTF-8" method="post"> <input type="text" value="123" name="bank_account[first_name]" id="bank_account_first_name"/> </form> <form class="edit_bank_accounts" id="edit_bank_account_2" action="/bank_account/2" accept-charset="UTF-8" method="post"> <input type="text" value="456" name="bank_account[first_name]" id="bank_account_first_name"/> </form>
But what I want is <form class="edit_bank_accounts" id="edit_bank_account" action="/bank_account" accept-charset="UTF-8" method="post"> <input type="text" value="123" name="bank_account[1][first_name]" id="bank_account_first_name"/> <input type="text" value="456" name="bank_account[2][first_name]" id="bank_account_first_name"/> </form>
How to generate bank_account[id][first_name] for the form in Ruby on Rails? Thanks. |
| rails4-autocomplete gem using mulitple options. Getting extra data from search with multiple => true Posted: 25 Jul 2016 08:10 AM PDT I have a table where I am searching by name of payer, put then using the payer_id in the input b/c I am then using it in an API call. My problem is I can't get multiple => true option with gem to work while using :extra_data. I either get extra_data option to work or the multiple => true option to work. If anyone has experience with this, help is much appreciated. Code is below: controller: autocomplete :payer, :payer_name, :full => true, :limit => 100, :extra_data => [:payer_id]
view: <div class:"form-group "> <%= label_tag :payer_id, "Payer Id", class: "control-label" %> <%= autocomplete_field_tag "payer_id", "", autocomplete_payer_payer_name_insurances_path, :update_elements => {:payer_id => '#payer_id'}, 'data-delimiter' => ',', :multiple => true %> </div>
I've tried reordering them a number different ways, nothing seems to work. Multiple true seems to be the dominate option. |
| What is the accepted way for admin-only tasks Posted: 25 Jul 2016 08:20 AM PDT I'm not using devise for learning purposes. I want admins to be able to access an admin-only page.

| Dividing up an index params into multiple pages Posted: 25 Jul 2016 07:55 AM PDT I have a list of records that I have displayed on an index page. (they are displayed in a table form). Because there are a number of them I am trying to divide them up to about 30 records per page. I've created a search params functionality with the index displayed beneath it. The problem that I am having is that I am having trouble getting more than one page to render on my list. As of right now I have about 150 records. However I only have one page listed with only 30 records on it and am not able to sort through them. Would anybody have any idea what I could be missing? Here is the segment in my code where this gets addresssed. def search_params default_index_params.merge(params.fetch(:record_collection, {})).with_indifferent_access end def default_index_params { per: 30, page: 1, sort_by: "created_at", sort_direction: "desc", customer_id: 0 } end
In my view, I do have a little bit of coffee-script that plays a role in the table itself. I don't know if it is the root of my problem, but I have it here as well. :coffeescript $('#record_table').dataTable aaSorting: [[1, 'asc']] bPaginate: false bFilter: false, aoColumns:[null, null, null, null, null, { bSortable: false }, null, { bSortable: false }]
My record collection is used for defining the params, i don't think that it is useful for this problem. (but could certainly post if needed) Thanks in advance to anybody who is able to help figure out what is going on with this. |
| Create new instance of Campaign in every iteration Posted: 25 Jul 2016 08:07 AM PDT I am working on functionality whereby a table is displayed with records, each with radio buttons Reject and Approve.

| Integration Tests: Filling Autocomple Dropdown in Rails_Admin using Capybara for Posted: 25 Jul 2016 07:47 AM PDT In my rails app, I'm using rails_admin. I want to fill a relationship. Say, a Post belongs to an Author. I want to set the author. rails_admin uses autocomplete form for selection of this data, i.e. xhr. How do I select value and submit this data using capybara. Normal select doesn't work here. I'm assuming I need to take following actions - Click on carrot icon,
- Select first value from dropdown
Or is there some other approach to fill such data, i.e execute script etc. But how do I do that? Thanks in advance, |
| RSpec throws a NoMethodError, but method works in the app Posted: 25 Jul 2016 08:13 AM PDT I have a method 'current_balance' defined in invoice.rb: belongs_to :purchase has_many :payments, dependent: :destroy validates :number, presence: true validates :currency, format: {with: /\A[A-Z]+\z/, message: "Please enter the 3 letter currency code in CAPS."} validates :total_due, presence: true validates :due_date, format: {with: /\d{4}-\d{2}-\d{2}/, message: "format must be YYYY-MM-DD"} validates :status, presence: true def current_balance self.current_balance = (self.total_due - self.payments.sum(:amount_paid)) end
The model spec, invoices_spec.rb contains: require "spec_helper" describe Invoice, '#current_balance' do it "calculates the current balance of an invoice" do invoice = FactoryGirl.create(:invoice, total_due: 200) invoice.payments << FactoryGirl.create(:payment, amount_paid: 100) invoice.payments << FactoryGirl.create(:payment, amount_paid: 50) expect(invoice.current_balance).to eq(50) end end describe Invoice do before(:all) { @invoice = FactoryGirl.build(:invoice) } it "has a valid factory" do expect(FactoryGirl.create(:invoice)).to be_valid end it "is invalid without a number" do invoice = Invoice.new(number: nil) expect(invoice).to_not be_valid end it "is invalid without a currency" do invoice = Invoice.new(currency: nil) expect(invoice).to_not be_valid end it "is invalid without a total_due" do invoice = Invoice.new(total_due: nil) expect(invoice).to_not be_valid end it "is invalid without a due_date" do invoice = Invoice.new(due_date: nil) expect(invoice).to_not be_valid end it "is invalid without a status" do invoice = Invoice.new(status: nil) expect(invoice).to_not be_valid end end
The method works perfectly and calculates the current balance of an invoice when I run the app. When I run the model spec, however, I get an error. The '#current_balance' & 'it has a valid factory' examples pass, the rest fail with the same error. Failure/Error: expect(invoice).to_not be_valid NoMethodError: undefined method `-' for nil:NilClass

| Using find_or_initialize on Rails 5 Posted: 25 Jul 2016 08:10 AM PDT I'm playing with Rails 5's find_or_initialize in my Blog app that has Posts and Categories entered into input text fields. Post model # == Schema Information # # Table name: posts # # id :integer not null, primary key # title :string default(""), not null # body :text default(""), not null # created_at :datetime not null # updated_at :datetime not null # category_id :integer class Post < ApplicationRecord validates :title, :body, :category, presence: true has_one :category accepts_nested_attributes_for :category end
Category model # == Schema Information # # Table name: category # # id :integer not null, primary key # name :string default(""), not null # created_at :datetime not null # updated_at :datetime not null class Category < ApplicationRecord validates :name, presence: true validates :name, length: { in: 3..80 } has_many :posts end
In the console I can get the following to work: post = Post.new(title: "Hello Stack Overflow", body: "How are you today?") post.category = Category.find_or_initialize_by(name: "Greetings") post.save post.last => #<Post:0x007fd34fa21a23 id: 42, title: "Hello Stack Overflow", body: "How are you today?", created_at: Mon, 25 Jul 2016 12:56:39 UTC +00:00, updated_at: Mon, 25 Jul 2016 12:56:39 UTC +00:00, category_id: 3>
The Post form looks like this: <%= form_for @post do |f| %> <fieldset> <%= f.label "Title" %> <%= f.text_field :body %> </fieldset> <fieldset> <%= f.fields_for :category do |category_fields| <%= f.label "Category" %> <%= category_fields.text_field :name %> <% end %> </fieldset> <% end %>
My trouble is trying to get what is entered in the category fields_for input into the Post model to use the find_or_initialize. I tried the following: class Post < ApplicationRecord before_save :generate_category? has_one :category accepts_nested_attributes_for :category private def generate_category? self.category = Category.find_or_initialize_by(name: name) end end
This fails and I'm getting an NameError error: NameError in PostController#create undefined local variable or method `name' for #<Listing:0x007fc3d9b48a48>
My question is: - How do I access the category attributes-is there a way to access the
nested_attributes in the model? - Am I using the right callback with
before_save - Should I be handling this in the controller somehow?
Any tips on how I can code this would be much appreciated. |
| RSpec when to use it should respond_to Posted: 25 Jul 2016 08:01 AM PDT I have two models linked together by a belongs_to and has_many relationship as shown below. Class OtherModel < ActiveRecord::Base belongs_to my_model end class MyModel < ActiveRecord::Base has_many other_models end
I now have the respective tests to verify that they have the correct relationship shown below. RSpec.describe MyModel, type: :model do it {should have_many(:other_models)} it {should respond_to(:other_models)} end RSpec.describe OtherModel, type: :model do it {should have_many(:my_model)} it {should respond_to(:my_model)} end
For this relationship, is the respond_to required, and if so why? What does it check for that the have_many does not already check for? If the respond_to is not needed in this case, when is an appropriate time to use it? From my current understanding have_many already verifies that the field exists, and thus obsoletes the respond_to check. |
| Defining a chained ruby method definition similar to rails Posted: 25 Jul 2016 08:21 AM PDT I am studying the Rails documentation. Within the associations documentation they specify method definitions with a chain on them, like this: Project#portfolio.nil? This seemed odd to me. It would appear that there is an instance method definition that has a chained method on it. For example: It appears thatProject#portfolio.nil? would define an instance method that would look like this: class Project < ActiveRecord::Base def portfolio.nil? ... end end
I have never seen instance methods defined like this before: where a chain is specified within the actual instance method definition. I attempted to replicate it with straight ruby and I couldn't get it to work. class Dog def speak puts "woof woof" end def speak.fetch puts "go get the ball!" end end
However this does not work. There is a NameError NameError: undefined local variable or method `speak' for Dog:Class If it did work: then I would try Dog.new.speak.fetch. I am not sure what it would return. Maybe it would return: => woof woof! => go get the ball!
Question: Is it even possible to somehow define instance method definitions with chains on them like this? If not: how does rails do it? Using Project#portfolio.nil? as an example: how does Rails go about defining #portfolio.nil? ? |

Customers controller class CustomersController < ApplicationController before_action :set_customer, only: [:show, :edit, :update, :destroy] # POST /customers.json def create @customer = Customer.new(customer_params) respond_to do |format| if @customer.save format.html { redirect_to @customer, notice: 'Customer was successfully created.' } format.json { render :show, status: :created, location: @customer } else format.html { render :new } format.json { render json: @customer.errors, status: :unprocessable_entity } end end end def update respond_to do |format| if @customer.update(customer_params) format.html { redirect_to @customer, notice: 'Customer was successfully updated.' } format.json { render :show, status: :ok, location: @customer } else format.html { render :edit } format.json { render json: @customer.errors, status: :unprocessable_entity } end end end private # Use callbacks to share common setup or constraints between actions. def set_customer @customer = Customer.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def customer_params params.require(:customer).permit(:first_name, :last_name, :phone_number, :sex, :book_rooms_attributes => [:checked_out]) end

| Split parameters into component parts Posted: 25 Jul 2016 05:24 AM PDT I have the following parameters when I process a form with multiple records. I wish to be able to take each individual campaign and process it accordingly. Parameters: {"utf8"=>"✓", "authenticity_token"=>"F2Mciu313dYUBOh7Ju0gSXrKa/yz6D6qZlVBMKOch4k=", "campaign"=>{"2"=>{"start_date"=>"2016-07-18 15:43:00", "end_date"=>"2016-10-15 12:20:00", "merchant_revenue"=>"10", "status"=>"Rejected", "notes"=>"aaaaaaaaaaaaaaaaaaaaaaaaaaa"}, "1"=>{"start_date"=>"2016-07-15 12:20:00", "end_date"=>"", "merchant_revenue"=>"10", "status"=>"Rejected", "notes"=>"bbbbbbbbbbbbbbbbbbbbbbbbbb"}}, "Commit"=>"Process"}
How do I split this data so each record has a campaign contained within. Thanks. |

| Invalid HTTP format, parsing fails Posted: 25 Jul 2016 04:32 AM PDT I was trying to make sure code I have written in Rails only runs on the development environment. So I tried to starts the rails server with a production environment via command: rails s -e production
I started to see the error: Invalid request: Invalid HTTP format, parsing fails. /home/mark/.rvm/gems/ruby-2.1.5/gems/thin-1.6.1/lib/thin/request.rb:84:in `execute' /home/mark/.rvm/gems/ruby-2.1.5/gems/thin-1.6.1/lib/thin/request.rb:84:in `parse' /home/mark/.rvm/gems/ruby-2.1.5/gems/thin-1.6.1/lib/thin/connection.rb:41:in `receive_data' /home/mark/.rvm/gems/ruby-2.1.5/gems/eventmachine-1.0.7/lib/eventmachine.rb:187:in `run_machine' /home/mark/.rvm/gems/ruby-2.1.5/gems/eventmachine-1.0.7/lib/eventmachine.rb:187:in `run' /home/mark/.rvm/gems/ruby-2.1.5/gems/thin-1.6.1/lib/thin/backends/base.rb:73:in `start' /home/mark/.rvm/gems/ruby-2.1.5/gems/thin-1.6.1/lib/thin/server.rb:162:in `start' /home/mark/.rvm/gems/ruby-2.1.5/gems/rack-1.5.5/lib/rack/handler/thin.rb:16:in `run' /home/mark/.rvm/gems/ruby-2.1.5/gems/rack-1.5.5/lib/rack/server.rb:264:in `start' /home/mark/.rvm/gems/ruby-2.1.5/gems/railties-4.1.7/lib/rails/commands/server.rb:69:in `start' /home/mark/.rvm/gems/ruby-2.1.5/gems/railties-4.1.7/lib/rails/commands/commands_tasks.rb:81:in `block in server' /home/mark/.rvm/gems/ruby-2.1.5/gems/railties-4.1.7/lib/rails/commands/commands_tasks.rb:76:in `tap' /home/mark/.rvm/gems/ruby-2.1.5/gems/railties-4.1.7/lib/rails/commands/commands_tasks.rb:76:in `server' /home/mark/.rvm/gems/ruby-2.1.5/gems/railties-4.1.7/lib/rails/commands/commands_tasks.rb:40:in `run_command!' /home/mark/.rvm/gems/ruby-2.1.5/gems/railties-4.1.7/lib/rails/commands.rb:17:in `<top (required)>' script/rails:6:in `require' script/rails:6:in `<main>'
So I killed the server and ran rails s. However, I continue to get this error no matter what I try. What can i do? |
| Rspec testing POROs included in models rails Posted: 25 Jul 2016 05:08 AM PDT In my Order model I include a PORO class "ShipmentHandler". This PORO is located like this: app/models/order/shipment_handler.rb I invoke this in my Order model like so: def assign_shipments ShipmentHandler.new(self).assign_shipments end
My PORO looks like: class Order class ShipmentHandler def initialize(order) @set_some_variables end def some_methods end end end
I'm trying to create spec to test the methods in my ShipmentHandler class. I'm not sure how to do this as I keep getting errors like uninitialized constant ShipmentHandler I've tried to add it to my order_spec.rb like so: describe Order do describe Order::ShipmentHandler do end end
and: describe Order do describe ShipmentHandler do end end
Neither work. I've also tried creating a spec in spec/models/order/shipment_handler_spec.rb This also failed. |
