问题
I am making a polymorphic association with devise and simple for but for some reason i cant get the params to work
here is my code:
User:
class User < ActiveRecord::Base
devise :database_authenticatable,
:rememberable, :trackable, :validatable
belongs_to :loginable, polymorphic: true
end
Designer:
class Designer < ActiveRecord::Base
has_one :user, as: :loginable
accepts_nested_attributes_for :user
end
Layout:
<%= simple_form_for [:admin, @designer] , :html => { :class => 'form-horizontal' } do |f| %>
<% if f.error_notification %>
<div class="alert alert-error fade in">
<a class="close" data-dismiss="alert" href="#">×</a>
<%= f.error_notification %>
<% if @designer.errors.any? %>
<ul>
<% @designer.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
<% end %>
</div>
<% end %>
<div class="control-group">
<%= f.label :profile_name, :class => 'control-label' %>
<div class="controls">
<%= f.text_field :profile_name, :class => 'text_field' %>
</div>
</div>
<%= f.simple_fields_for users do |u| %>
<div class="control-group">
<%= u.label :email, :class => 'control-label' %>
<div class="controls">
<%= u.text_field :email, :class => 'text_field' %>
</div>
</div>
<div class="control-group">
<%= u.label :password, :class => 'control-label' %>
<div class="controls">
<%= u.password_field :password, :class => 'text_field' %>
</div>
</div>
<div class="control-group">
<%= u.label :type, :class => 'control-label' %>
<div class="controls">
<%= u.input :role, :label => false do %>
<%= u.select :role_id, Role.all.map { |r| [r.name, r.id] } %>
<% end %>
</div>
</div>
<div class="control-group">
<%= u.label :firstname, :class => 'control-label' %>
<div class="controls">
<%= u.text_field :firstname, :class => 'text_field' %>
</div>
</div>
<% end %>
<div class="form-actions">
<%= f.submit nil, :class => 'btn btn-primary' %>
</div>
<% end %>
Controller:
def create
@user = User.new(designer_params)
@designer = Designer.new(designer_params)
@user.loginable = @designer
respond_to do |format|
if @user.save! && @designer.save!
format.html { redirect_to admin_designers_path, notice: 'Designer was successfully created.' }
format.json { render action: 'show', status: :created, location: admin_designer_path(@designer) }
else
format.html { render action: 'new' }
format.json { render json: [designer: @designer.errors, user: @user.errors], status: :unprocessable_entity }
end
end
end
def designer_params
params.permit(:profile_name, :user, user_attributes: [:email, :password, :password, :firstname, :lastname, :address, :postalcode, :city, :country, :role, :role_id])
end
My params seems to ignore the user attributes, i only see profile name for some reason.
Any ideas on how to fix this would be greatly appreciated
Thanks!

I managed to resolve my own issues. so i am posting the answer hoping to save someone else lots of time.
i ended up creating another private method for the user params
def designer_params
params.require(:designer).permit(:profile_name, user_attributes: [:email, :password, :password, :firstname, :lastname, :address, :postalcode, :city, :country, :role, :role_id])
end
def user_params
params[:designer][:user_attributes].permit(:email, :password, :password, :firstname, :lastname, :address, :postalcode, :city, :country, :role, :role_id)
end
and then using those to create my relationship
def create
@designer = Designer.new(designer_params)
@user = User.new(user_params)
@user.loginable = @designer
@designer.save!
end
also if you are having trouble viewing the nested form make sure to use the build_ method
def new
@designer = Designer.new
@user = @designer.build_user
end
