    <p>I am trying to create an application having domains and users, there are 3 types of users, super admin,domain admins and domain users.All the users(3 types) are in the users table and domains in domain table. At present there are domains and super admin. A super admin can login and create domains and domain users. The domains users should be related to a particular domain(i have a "domain_id" column in my 'users' table).Now when i am trying to create a user under a domain(after selecting a domain), i am getting this error "undefined method `users' for nil:NilClass".</p> <p>My user controller.</p> <pre><code>def new @domain = Domain.find(params[:id]) @user = User.new @title = "Sign up" end def create @user = @domain.users.build(params[:user]) if @user.save flash[:success] = "Welcome to My Space!" redirect_to @user else @title = "Sign up" render 'new' end end </code></pre> <p>My user model is having.<br/> belongs_to :domain<br/> validates :domain_id, :presence => true<br/> <br/> and domain model is having.<br/> has_many :users<br/></p> <p>My new.html.erb form</p> <pre><code>&lt;%= form_for @user do |f| %&gt; &lt;%= f.label :first_name %&gt; &lt;%= f.text_field(:first_name, :size =&gt; 20) %&gt; &lt;%= f.label :last_name %&gt; &lt;%= f.text_field(:last_name, :size =&gt; 20) %&gt; &lt;%= f.label :email %&gt; &lt;%= f.text_field(:email, :size =&gt; 20) %&gt; &lt;%= f.label :password %&gt; &lt;%= f.password_field(:password, :size =&gt; 20) %&gt; &lt;%= f.label :password_confirmation, "Verify Password" %&gt; &lt;%= f.password_field(:password_confirmation, :size =&gt; 20) %&gt; &lt;%= f.submit "Create" %&gt; &lt;% end %&gt; </code></pre>

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.
