    <p>I am using nested forms to insert data into two tables (user and address).I want to have my users email id in both the table, but the user should enter the email id once. Here is my current view</p> <pre><code>&lt;%= form_for @user do |f| %&gt; &lt;%= f.text_field(:name, :size =&gt; 20) %&gt; &lt;%= f.text_field(:email, :size =&gt; 20) %&gt; &lt;%= f.fields_for :address do |r| %&gt; &lt;%= r.text_field(:street, :size =&gt; 20) %&gt; &lt;%= r.text_field(:city, :size =&gt; 20) %&gt; &lt;% end %&gt; &lt;%= f.submit "Create" %&gt; &lt;% end %&gt; </code></pre> <p>In my nested section "address" i once again want the email field, but i don't want a repeated text field for email. How can i use the email section inside the nested form "address"? I have tried using hidden form fields, but it didn't worked. Can somebody help please. </p> <p>EDIT</p> <p>Controller(Only question related parts)</p> <pre><code>class UsersController &lt; ApplicationController def new @domain = Domain.find(params[:id]) @user = @domain.users.build @title = "Add User" end def create @user = User.new(params[:user]) if @user.save flash[:success] = "Welcome!" redirect_to manageDomain2_path(:id =&gt; @user.domain_id) else @title = "Add User" redirect_to addNewUser_path(:id =&gt; @user.domain_id) end end </code></pre> <p>I have tried with:</p> <pre><code>@user = User.new(params[:user][:address_attributes].merge!(:email =&gt; params[:user][:email])) </code></pre> <p>When using:</p> <pre><code>@user = User.new(params[:user][:address].merge!(:email =&gt; params[:user][:email])) </code></pre> <p>I am getting error "Undefined method merge".</p> <p>User Model (Question related portion only)</p> <pre><code>class User &lt; ActiveRecord::Base attr_accessible: :email, :domain_id, :address_attributes belongs_to :domain has_one :address accepts_nested_attributes_for :address end </code></pre> <p>Address Model (Full)</p> <pre><code>class Address &lt; ActiveRecord::Base attr_accessible :user_id, :email, :street, :city end </code></pre> <p>When i use </p> <pre><code>belongs_to :user </code></pre> <p>in address model i get syntax error. So i have tried without using it. the user_id, street, city is getting proper values but email email field is not getting any thing.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
