Creating Two Models in One Form (Page 3 of 6)

Is the column called "projecttemplate_id" exactly? Try creating the two models in script/console and see if you get the same results.

Ryan,
You really are incredible with your support of us newbies - really do appreciate it - can't believe you responded so quickly - you must be glued to this stuff!  All fixed!

Try this:

# view
<%= link_to 'delete', { :controller => 'templatetask', :action => 'destroy', :id => templatetask }, :confirm => 'Are you sure?' %>
# controller
def destroy
    @task = Templatetask.find(params[:id]).destroy
    redirect_to :controller => 'projecttemplate', :action => 'edit', :id => @task.projecttemplate_id
  end

Any experience working with the RoR sublist plugin for making these types of forms more live?  Words of advice greatly appreciated...

Hooray I've fixed my problem. In case anyone is wondering the following worked.

def create
    @stone = Stone.new(params[:stone])
    @image = @stone.build_image(params[:image])
    
    if @stone.save
      flash[:notice] = 'Stone was successfully created.'
      redirect_to :action => 'index'
    else
      render :action => 'new'
    end
  end

<%= error_messages_for :stone, :image %>

<% form_for(:stone, @stone, :url => {:action => 'create'}, :html => { :multipart => true }) do |f| %>
  <p>
    Name<br />
    <%= f.text_field :name %>
  </p>
  <p>
    Description<br />
    <%= f.text_area :description %>
  </p>
  <p>
    Price Per m<sup>3</sup><br />
    <%= f.text_field :price_per_m3 %>
  </p>
  <% fields_for(:image, @stone.image) do |i| %>
    <p>
      Upload An Image
      <%= i.file_field :uploaded_data %>
    </p>
  <% end %>
  <p>
    <%= submit_tag 'Create'%>
  </p>
<% end %>

Does using the "build" also handle foreign key building?

My primary table (i.e. Projects) record id is used as a foreign key in my child table (i.e. tasks). Does BUILD handle the generation and insertion of the foreign key?

Thanks for a great tutorial. I have a slight problem with my script.  Everything works fine but I want to change the formatting of the error messages when validation catches something.  Right now I have three models/databases being affected by 1 form.  Users, Profiles, PersonalInfo.  While PersonalInfo is not sending anything to the db I want it to create a field so Users can reference it by it's ID.

My problem is I get two seperate validation errors that looks like this.

3 errors prohibited this user from being saved
There were problems with the following fields:

    * Profile is invalid
    * User name can't be blank
    * Password can't be blank

2 errors prohibited this profile from being saved
There were problems with the following fields:

    * City can't be blank
    * Full name can't be blank

Here is my code

users_controller.rb

def new
    @user = User.new
    @profile = Profile.new
  end
  def create
    @user = User.new(params[:user])
    @profile = @user.build_profile(params[:profile])
    @personal_info = @user.build_personal_info()
    @user.personal_info_id = @personal_info.id
    @user.profile_id = @profile.id;
    if @user.save && @profile.save && @personal_info.save
      flash[:notice] = 'User was successfully created.'
      redirect_to :action => 'welcome'
    else
      render :action => 'new'
    end
  end

profile.rb

class Profile < ActiveRecord::Base
  has_one :user
  validates_presence_of :full_name, :city, :state
end

user.rb

class User < ActiveRecord::Base
  belongs_to :profile
  belongs_to :personal_info
  
  validates_associated :profile
  validates_presence_of :user_name, :password
  validates_uniqueness_of :user_name
end

form

<%= error_messages_for 'user' %>
<%= error_messages_for 'profile' %>
<!--[form:user]-->
<p><label for="profile_full_name">Full name</label><br/>
<%= text_field 'profile', 'full_name'  %></p>
<p><label for="profile_location">Location</label><br/>
<%= text_field 'profile', 'city'  %>, <%= state_select('profile', 'state', country='US', options = {}, html_options = {}) %></p>
<p><label for="user_user_name">User name</label><br/>
<%= text_field 'user', 'user_name'  %></p>
<p><label for="user_password">Password</label><br/>
<%= password_field 'user', 'password'  %></p>
<!--[eoform:user]-->

Hi, this tutorial is helping me a lot.But i am developing a web application in ruby on rails.My application is as i have a signup page to enroll the user with stores the data in two tables one in user and one in contacts.Now i am not getting how to update the user profile after login can anybody suggest me.

Great tutorial; I've managed to get it to work, however,

It is difficult for me to understand how to add a second task to a project.

after adding a task I would have taks.id=1 and added task.id =2, iow two rows in 'tasks';
both of them should have project_id set to '1'.

Its probably quite easy once you know it, but I am having a really hard time to get the view and the controller right for this.

I greatly appreciate any help.
