nested attributes not displaying form correctly

Question

I have a form from user

<%= form_for(@user) do |f| %>
  <%= f.fields_for :businesses do |field| %>
    <div class="field">
      <%= field.label :address %>
      <%= field.text_field :address %>
    </div>   
    <div class="field">
      <%= field.label :city %>
      <%= field.text_field :city %>
    </div>  
  <% end %>
<% end %>

It does not display my fields, but when i change businesses to business, then it shows, or if I remove the f from f.fields_for. But I don't think it properly saves into database.

my user model

class User < ActiveRecord::Base
  has_many :businesses
  accepts_nested_attributes_for :businesses
en

my business model

class Business < ActiveRecord::Base
  attr_accessible :user_id, :address, :city
  belongs_to :user
end

my bussiness migration

class CreateBusinesses < ActiveRecord::Migration
  def change
    create_table :businesses do |t|
      t.integer :user_id
      t.string :address
      t.string :city

      t.timestamps
    end
  end
end

Any suggestions as to what I'm doing wrong?

Thanks

Does the User have any businesses yet?

You should build a business before it can display a form for it:

@user.businesses.build

Use that before using fields_for

Also check out this great gem for managing nested forms:

So user would need to have a business first before the form is displayed? But what if I want user to input a business?

hellomello Over a year ago

i was able to display the fields when I put <%= f.fields_for :businesses, @user.businesses.build do |field| %> But now when I save my database, the information doesn't show up in the field? Isn't my values should show up in the fields automatically if I want to edit my information? If I do <%= @user.businesses %> it shows my saved file.

And it just keeps adding new data when I try to insert more information into address and city field, Its supposed to override the original data?

I figured it out that I'm supposed to put the @user.businesses.build in my new action in users_controller

Found it : in a has_one relationship, it is @user.build_preferences. Found it thanks to this post: stackoverflow.com/questions/2472982/…
