[Rails] Re: form_tag + fields_for Rails 4

Have you tried with form_for instead of form_tag?

Hi There,

    I'm trying to user fields_for inside a form_tag, but i can't catch it on my controller. 

    I just take some html code off to makes it easy to read

   my view...  

  i'm using campuses_path(current_church, @campus) instead form_for @campus, because my route is like 

  resources :campuses, :path => ":church/campuses" 

<%= form_tag campuses_path(current_church, @campus),  :class => 'form-horizontal', :method => :post   do  %>
   <%= text_field  :campus, :name %>
   <%= text_area :campus, :description %>
  
  <%= fields_for :addresses do |b| %>
      <%= b.text_field  :street %>
      <%= b.text_field :street2 %>
      <%= b.text_field :city %>
      <%= b.text_field :state %>
      <%= b.text_field :zip_code %>
  <% end %>
  
  <input type='submit' value='Save' >
<% end %>

my controller

 

class CampusesController < ApplicationController
  def new
    @campus = Campus.new
  end
  
  def create
    @campus = Campus.new(campus_params)
    @campus.church_id = session[:church_id]
    # i'm just trying this way, because it's not creating automatic (accepts_nested_attributes_for)
    @campus.addresses.new(params[:addresses]) # the error line

    if @campus.save!
       ...      
    else
      ...
   end
  
  private
    
   # Never trust parameters from the scary internet, only allow the white list through.
    def campus_params
      params.require(:campus).permit(:name, :description, :cover, :addesses)
      # i've tried instead :addresses
      # {:addresses => []}
      # :addresses []
    end
  
end

my model

class Campus < ActiveRecord::Base
  belongs_to :church
  has_many :addresses, :as => :addressable
  
    
  accepts_nested_attributes_for :addresses
    
end

Request parameters

{"utf8"=>"✓", "authenticity_token"=>"B0OBKKM3PQ/Jkh1ebcKyrKZGJuauJeN3O/BWv8Vc7qE=", "campus"=>{"name"=>"Campus name", "description"=>"campus description"}, "addresses"=>{"street"=>"Street name", "street2"=>"", "city"=>"city name", "state"=>"state name", "zip_code"=>"00000"}, "action"=>"create", "controller"=>"campuses", "church"=>"greenhouse-church"}

Params at Controller: 

params[:addresses]  => {"street"=>"Street name", "street2"=>"", "city"=>"city name", "state"=>"state name", "zip_code"=>"00000"}  >> params[:campus]  => {"name"=>"Campus name", "description"=>"campus description"}  
>>

With this code the error is: 

ActiveModel::ForbiddenAttributesError

    @campus.addresses.new(params[:addresses])

Let me know if you need more information. 

Thank You,

André
