Hi,
I am having some issues when updating an object that has a nested
attribute.
My model objects are:
User
class User < ActiveRecord::Base
has_one :portal_user
accepts_nested_attributes_for :portal_user
validates_presence_of :username
end
PortalUser
class PortalUser < ActiveRecord::Base
belongs_to :user,:dependent => :destroy, :foreign_key
=> :user_id
end
I have got the action update defined in the User controller like
this:
class UsersController < ApplicationController
# PUT /users/1
# PUT /users/1.xml
def update
@user = User.find(params[:id])
respond_to do |format|
if @user.update_attributes(params[:user])
format.html { redirect_to(@user, :notice => 'User was
successfully updated.’) }
format.xml { head :ok }
else
flash[:error] = “Error while updating personnal
information.”
format.html { render :action => edit_profiles_path }
format.xml { render :xml => @user.errors, :status
=> :unprocessable_entity }
end
end
end
end
The update action for the PortalUser controller is also defined:
class PortalUsersController < ApplicationController
def update
@portal_user = PortalUser.find(params[:id])
respond_to do |format|
if @portal_user.update_attributes(params[:portal_user])
format.html { redirect_to(@portal_user, :notice =>
‘PortalUser was successfully updated.’) }
format.xml { head :ok }
else
flash[:error] = “Error while updating PortalUser.”
format.html { render :action => edit_profiles_path }
format.xml { render :xml => @portal_user.errors, :status
=> :unprocessable_entity }
end
end
end
end
And finally I have a Profile controller that hosts the nested form:
class ProfilesController < ApplicationController
def edit
# Note: I am using a hard coded Id on purpose.
@user = User.find(980190962)
end
end
View of the Profile’s action edit:
<%= form_for @user do |f| %>
<%= f.fields_for :portal_user do |f_portal_user| %>
<%= f_portal_user.label :firstname %> <br/>
<%= f_portal_user.text_field :firstname %> <br/>
<%= f_portal_user.label :lastname %> <br/>
<%= f_portal_user.text_field :lastname %> <br/>
<% end %>
<%= f.label :username %> <br/>
<%= f.text_field :username %><br/>
<%= f.fields_for :portal_user do |f_portal_user| %>
<%= f_portal_user.label :phone %> <br/>
<%= f_portal_user.text_field :phone %><br/>
<%= f_portal_user.label :cellular_phone %> <br/>
<%= f_portal_user.text_field :cellular_phone %><br/>
<% end %>
<%= submit_tag "Update" %>
<% end %>
When I go to the edit page, I can see the information of the user
(both @user and @portal_user) loaded into the form but when I edit the
form and send the update nothing happens!
To help you discover the origin of my problem here is the ‘trace’ (in
this I tried to rename to change the username field from Amokrane to
amk:
