You can't have a form inside of another one. Maybe I am misunderstanding?

I am pretty sure you have have nested forms....:slight_smile:

my nested form looks like

<% form_for :doctor, :url => url do |doc_form| %>

  <table>    <tr>        <td> <%= doc_form.label :"Specialized Field: " %> </td>        <td> <%= doc_form.text_field :specialize %> </td>     </tr>   <tr>        <td> <%= doc_form.label :"Medical Center Name: " %> </td>        <td> <%= doc_form.text_field :working_for %> </td>     </tr>     <% doc_form.fields_for :user, :url => url do |f| %>

       <tr>            <td> <%= f.label :"First Name: " %> </td>            <td> <%= f.text_field :fname %> </td>         </tr>                   ..................... I want to display validation errors for both doctor and user...my create action in the controller looks like

  def create     doc_attr = params[:doctor]     user_attr = doc_attr.delete(:user)     new_doctor = Doctor.new(doc_attr)     new_doctor.user = User.new(user_attr)     @saved = new_doctor.save!

    if @saved == true       flash[:notice] = "Registration Successful"       redirect_to login_path()     else       render :action => 'new'     end end

Thank you

Instead of having to manually create your child user at the controller- level, have a look at this:

And the API documentation is at:

you can have fields_for to nest a “form” for a child object

I thought he meant he had 2 form tags, one inside of another.

I think you might be missing something in your models.

In the Doctor model you should have:

  has_many :users   accepts_nested_attributes_for :users

In the User model you should have:

  belongs_to :doctor

I think I've run into the same problem before and it was due to the fact that I was missing the 'accepts_nested_attributes_for'.
