nested-forms

I want to include a collection type inside another collection type. It should look like this: Using just one collection works fine, but I need to edit the prototype of the outer form, so it renders the prototype of the inner form for each line. Any ideas how could I do that? Also what would be the best way to save EDIT: Now I am trying to render the prototype of the nested form: <ul class="characteristics-container" data-prototype="{{ form_widget(form.characteristics.vars.prototype)|e }}" data-prototype-options="{{ form_widget(form.characteristics.options.vars.prototype|e ) }}"> {# iterate

I have a basketball app, where a Roster has many Players, and a Player can be on multiple Rosters.(Reason for many-to-many is for a Player-Roster archive) Roster.rb class Roster < ActiveRecord::Base belongs_to :team has_many :rosterizes has_many :players, :through => :rosterizes accepts_nested_attributes_for :players attr_accessible :jersey_number, :team_id, :class_year, :players end Rosterizes.rb (poorly named I know...) class Rosterize < ActiveRecord::Base belongs_to :player belongs_to :roster attr_accessible :player_id, :roster_id end Player.rb class Player < ActiveRecord::Base has_many

I have a one-to-many association between a Banana model and an Image model. In addition, each Banana and Image belong to a User (via a separate association because an Image and its Banana might have different Users). I would like a nested form to create Bananas as well as Images. The kicker is that I don't know how many Images to build (note the multiple attribute). The commented out bit of the form below will create the appropriate amount of Images, but won't complete the associated User reference. Is there a way to accomplish this with fields_for (so the associations are completed) as I've

I am trying to reproduce railscast #196 in Rails 4. However, I'm experiencing some problems. In my example I try to generate a Phonebook - each Person could have multiple PhoneNumbers These are important parts of my controller: class PeopleController < ApplicationController def new @person = Person.new 3.times{ @person.phones.build } end def create @person = Person.create(person_params) @person.phones.build(params[:person][:phones]) redirect_to people_path end private def person_params params.require(:person).permit(:id, :name, phones_attributes: [ :id, :number ]) end end and this is my new

I cannot seem to get nested attributes to save to the database. I am using Rails 4. Here are my models : class Answer < ActiveRecord::Base belongs_to :question end class Question < ActiveRecord::Base has_many :answers belongs_to :survey accepts_nested_attributes_for :answers, allow_destroy: true end class Survey < ActiveRecord::Base has_many :questions validates_presence_of :name accepts_nested_attributes_for :questions end Here is the controller: def create @survey = Survey.new(survey_params) respond_to do |format| if @survey.save format.html { redirect_to @survey, notice: 'Survey was

I have the following models class Order < AR::Base has_many :products accepts_nested_attributes_for :products end class Product < AR::Base belongs_to :order has_and_belongs_to_many :stores accepts_nested_attributes_for :stores end class Store < AR::Base has_and_belongs_to_many :products end Now I have a order view where I want to update the shops for the product. The thing is that I only want to connect the products to the existing shops in my db, not create new ones. My form in the order view looks like this (using Formtastic): = semantic_form_for @order do |f| = f.inputs :for => :live

I have a user and a profile model. One user can have many profiles. I need to access only one information from the profiles section (viz the phone number) in my user model during the user creation process. Hence I'm trying to get it done through attr_accessible . My user.rb looks like this. has_many :profiles attr_accessible :handle, :email, :password, :profile_mobile_number attr_accessor : :profile_mobile_number The problem that I'm facing is that when I try to call the getter method profile_mobile_number in a method in user.rb (the method is private, though I think it doesn't matter), I'm

How can I generate form fields for a has_many :through association that has additional attributes? The has_many :through relationship has an additional column called weight . Here's the migration file for the join table: create_table :users_widgets do |t| t.integer :user_id t.integer :widget_id t.integer :weight t.timestamps end The models look like this: User has_many :widgets, :through => :users_widgets, :class_name => 'Widget', :source => :widget has_many :users_widgets accepts_nested_attributes_for :widgets # not sure if this is necessary Widget has_many :users, :through => :users_widgets,

I have the following code in my models: Class Farm < ActiveRecord::Base has_many :farm_products, :dependent => :destroy has_many :products, :through => :farm_products accepts_nested_attributes_for :farm_products end class Product < ActiveRecord::Base has_many :farm_products, :dependent => :destroy has_many :farms, :through => :farm_products end class FarmProduct < ActiveRecord::Base belongs_to :farm belongs_to :product end I have a form to create a new Farm, and I want to create farm_products along with this form. My farm_products table can not only contain foreign key fields. How can I add or
