I have this _form file.
<%= form_for(#company) do |f| %>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :company_type %>
<%= f.select :company_type_id, CompanyType.order(:name).map{|x| [x.name, x.id]} %>
<%= f.label :description %>
<%= f.text_area :description %>
<%= f.submit %>
<% end %>
My question is how do I change select
<%= f.select :company_type_id, CompanyType.order(:name).map{|x| [x.name, x.id]} %>
in this form into checkbox list?
CompanyType model:
class CompanyType < ActiveRecord::Base
attr_accessible :name
has_many :companies
end
Company model:
class Company < ActiveRecord::Base
attr_accessible :description, :name, :company_type_id, :website
belongs_to :type, :class_name => "CompanyType", :foreign_key => :company_type_id
end
Try this
<%= f.check_box :company_type_id, CompanyType.order(:name).map{|x| [x.name, x.id]} %>
Try the checkboxes_select method

I added a nested attribute to my form, the fields for the nested attribute which is Education fields do not render, the other fields do. The relationships appear to be in order and the controller does too.
Here is the code.
Controller
def new
#profile = current_user.build_student_profile
end
def profile_params
params.require(:student_profile).permit(:first_name, :last_name, :gender, student_profiles_attributes: [:degree, :university_id, :major, :major2, :start_date, :end_date, :grade, :grade_scale] )
end
Models
class Education < ActiveRecord::Base
belongs_to :student_profile
belongs_to :university
validates :grade_scale, inclusion: { in: %w(GPA4 GPA7 WAM100) }
validates :degree, :university_id, :major, :start_date, :end_date, :grade, :grade_scale, presence: true
end
class StudentProfile < ActiveRecord::Base
belongs_to :user
has_many :educations
validates :gender, inclusion: { in: %w(male female) }
validates :first_name, :last_name, :gender, presence: true
accepts_nested_attributes_for :educations
end
Form
<%= form_for (#profile) do |f| %>
<%= f.label :first_name %>
<%= f.text_field :first_name %>
<%= f.label :last_name %>
<%= f.text_field :last_name %>
<%= f.label :gender %>
<%= f.text_field :gender %>
<%= f.fields_for :educations do |education_fields| %>
<%= education_fields.label :Degree %>
<%= education_fields.text_field :degree %>
<%= education_fields.label :University %>
<%= education_fields.collection_select(:university_id, University.all, :id, :name) %>
<%= education_fields.label :Major %>
<%= education_fields.text_field :major %>
<%= education_fields.label :Additional_Major %>
<%= education_fields.text_field :major2 %>
<%= education_fields.label :Start_Date %>
<%= education_fields.date_field :start_date %>
<%= education_fields.label :End_Date %>
<%= education_fields.date_field :end_date %>
<%= education_fields.label :Grade %>
<%= education_fields.number_field :grade %>
<%= education_fields.label :Grade_Scale %>
<%= education_fields.select :grade_scale, [["GPA / 4","GPA4"], ["GPA / 7","GPA7"], ["WAM / 100","WAM100"]] %>
<% end %>
<%= f.submit :submit %>
<% end %>
I have tried to add the following to the controller new action #profile.educations.build but I get an error unknown attribute student_profile_id
Can anyone help ?
Make sure you have student_profile_id attribute/column present in educations table.
After that, as you have mentioned, you need to build educations object on student_profile as:
def new
#profile = current_user.build_student_profile
#profile.educations.build
end
Try this
<%= f.fields_for(:educations,#profile.educations.build) do |education_fields| %>
<% end %>
or
def new
#profile = current_user.build_student_profile
#educations = #profile.educations.build
end
<%= f.fields_for(#educations) do |education_fields| %>
<% end %>
There is a User model and Company model.
User.rb
class User < ActiveRecord::Base
has_and_belongs_to_many :companies
end
Company.rb
class Company < ActiveRecord::Base
has_and_belongs_to_many :users
end
New.html.erb
<%= simple_form_for(#user) do |f| %>
<% if policy_scope(Company).count <= 1 %>
<%= f.label :company, "Company: "%><br />
<%= f.text_field :company, :value => policy_scope(Company).first %><br /><br />
<% else %>
<%= f.association :company, collection: policy_scope(Company).all, prompt: "Choose a Company", :required => true %>
<% end %>
<%= f.input :username, :required => true %>
<%= f.input :display_name, :required => true %>
<div class="form-actions">
<%= f.button :submit, :class => 'btn-primary' %>
</div>
<% end %>
f.association is failing saying :company not found. If policy_scope(Company).count <= 1 then code in that condition works fine.
Please say if you need more code. Thank you
How do you correctly fill in the following syntax to create a dropdown select tag with each option being the data of another table?
<%= form_for(#celebrity, :html => { :multipart => true }) do |f| %>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :image %>
<%= f.file_field :image %>
<%= f.label :character %>
<%= f.collection_select(:character, :celebrity_id, #characters, :id, :name) %> #this line is the question
<%= f.submit 'Save' %>
<% end %>
I followed the API documentation here, but it doesn't seem to work.
http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-collection_select
class Celebrity < ActiveRecord::Base
has_many :characters, through: :char_celeb_joins
has_many :char_celeb_joins
has_many :universes, through: :characters
end
class Character < ActiveRecord::Base
has_many :universes, through: :univ_char_joins
has_many :univ_char_joins
has_many :celebrities, through: :char_celeb_joins
has_many :char_celeb_joins
end
class Universe < ActiveRecord::Base
has_many :characters, through: :char_univ_joins
has_many :char_univ_joins
has_many :celebrities, through: :characters
end
But I get a
undefined method 'merge' for :name:Symbol
in the browser, when I go to a view that brings up this code.
NoMethodError in Celebrities#edit
The error is due to this line
<%= f.collection_select(:character, :celebrity_id, #characters, :id, :name) %>
When using with form_for,you have to set it like this
<%= f.collection_select(:celebrity_id, #characters, :id, :name) %>
And also your form_for object is #celebrity and you are giving :character as object to collection_select.It should be :celebrity in the collection_select too.Ofcourse you have worry about this when using collection_select without form_for.In your case it would be
<%= collection_select(:celebrity, :celebrity_id, #characters, :id, :name) %>
You can use helper:
Writer this code in any of the helper:
def character_for_select
Character.all.collect { |m| [m.id, m.name] }
end
Update your form
<%= form_for(#celebrity, :html => { :multipart => true }) do |f| %>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :image %>
<%= f.file_field :image %>
<%= f.label :character %>
<%= f.select(:character, character_for_select, :prompt => 'Select character') %>
<%= f.submit 'Save' %>
<% end %>
You will get your answer :)
Have you tried to use options_for_select. In your case, your code should be something like this:
app/helpers...
def options_for_characters( selected=nil )
options = Character.all.map { |c| [d.id, c.name] }
options_for_select( options, selected )
end
app/views...
...
<%= f.select(:character, options_for_characters, :prompt => 'Select character') %>

I have a BikeShops model:
class BikeShop < ActiveRecord::Base
has_one :user, :as => :profile, :dependent => :destroy
accepts_nested_attributes_for :user
end
And a Users model:
class User < ActiveRecord::Base
belongs_to :profile, :polymorphic => true
end
I am trying to create a nested form in the bike_shops/new view. Here is the code I have: in there:
<%= form_for(#bike_shop) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<%= f.label :name, 'Shop Name' %>
<%= f.text_field :name %>
<%= f.label :street_address, 'Street Address' %>
<%= f.text_field :street_address %>
<%= f.label :city, 'City' %>
<%= f.text_field :city %>
<%= f.label :state, 'State' %>
<%= f.text_field :state %>
<%= f.label :zip_code, 'Zip Code' %>
<%= f.text_field :zip_code %>
<%= f.label :phone_number, 'Phone Number' %>
<%= f.text_field :phone_number %>
<%= f.label :website, 'Website' %>
<%= f.text_field :website %>
<% f.fields_for(:user) do |builder| %>
<%= builder.label :first_name, 'First Name:' %>
<%= builder.text_field :first_name %>
<%= builder.label :last_name, 'Last Name:' %>
<%= builder.text_field :last_name %>
<%= builder.label :email, 'Email:' %>
<%= builder.text_field :email %>
<%= builder.label :password, 'Password:' %>
<%= builder.password_field :password %>
<%= builder.label :password_confirmation, 'Password Confirmation:' %>
<%= builder.password_field :password_confirmation %>
<% end %>
<%= f.submit "Signup My Bike Shop", class: "btn btn-large btn-primary" %>
<% end %>
The fields for #bike_shop appear but the nested fields for the has_one #user do not appear. Here is the code in the BikeShops controller:
class BikeShopsController < ApplicationController
def new
#bike_shop = BikeShop.new
#user = #bike_shop.build_user
end
I was following this railscast but can't get pass getting the fields for the nested form to show. Any help is appreciated.
You need to use the <%= erb tag in order to render it instead of just <%
<%= f.fields_for(:user) do |builder| %>
I have a model Contact which has a many-to-many relationship with Company:
class Contact < ActiveRecord::Base has_many :contactcompanies
has_many :companies, through: :contactcompanies
Company model:
class Company < ActiveRecord::Base
has_many :contactcompanies
has_many :contacts, through: :contactcompanies
ContactCompany:
class ContactCompany < ActiveRecord::Base
belongs_to :company
belongs_to :contact
contacts_controller.rb:
def new
#contact = Contact.new
#all_companies = Company.all
#contact_company = #contact.contactcompanies.build
end
contact create form where I want to have a multiple select for companies:
<%= form_for #contact do |f| %>
<%= f.label :first_name %>
<%= f.text_field :first_name %>
<%= f.label :last_name %>
<%= f.text_field :last_name %>
<%= f.label :image_url %>
<%= f.text_field :image_url %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= fields_for(#contact_company) do |cc| %>
<%= cc.label "All Companies" %>
<%= collection_select(:companies, :id, #all_companies, :id, :name, {}, { :multiple => true }) %>
<% end %>
<div class="form-action">
<%= f.submit nil, :class => 'btn btn-primary' %>
<%= link_to t('.cancel', :default => t("helpers.links.cancel")),
contacts_path, :class => 'btn' %>
</div>
<% end %>
My issue is when I go to /contacts/new I get this error:
Circular dependency detected while autoloading constant Contactcompany
Any ideas? I'm searching for hours without success. Thanks
You have declared your class as "ContactCompany"
This implies:
has_many :contact_companies
has_many :contacts, through: :contact_companies
Without the underscore, it is looking for a class named Contactcompany, which does not exist.
