Am getting the following error:
Modul(#36555780) expected, got String(#21132310)
After doing a lot of research on the net, i found that i need to pass
on the id field somehow, but i dont really know how to do it.
Following is the model:
---------------------------------
class Modul < ActiveRecord::Base
belongs_to :modulable, :polymorphic => true
end
class Chapter < ActiveRecord::Base
has_many :moduls, :as => :modulable
accepts_nested_attributes_for :moduls
end
New Page:
----------------
<h1>New chapter</h1>
<% form_for @chapter do |chapter_form| %>
<%= chapter_form.error_messages %>
<% chapter_form.fields_for :moduls do |modul_form| %>
<p>
<%= modul_form.label :name %><br />
<%= modul_form.text_field :name %>
</p>
<p>
<%= modul_form.label :alias %><br />
<%= modul_form.text_field :alias %>
</p>
<p>
<%= modul_form.label :description %><br />
<%= modul_form.text_field :description %>
</p>
<p>
<%= modul_form.label :level %><br />
<%= modul_form.select :level, %w{ nil 0 1 2 3 } %><br />
</p>
<p>
<%= modul_form.label :parent %><br />
<%= modul_form.text_field :parent %>
</p>
<% end %>
<p>
<%= chapter_form.label :chapter_type %><br />
<%=
#...@decodes = Decode.find(:all, :conditions => {:name =>
"Chapter_Type", :is_active => 1 })
@decodes = Decode.all(:conditions => {:name =>
"Chapter_Type", :is_active => 1 })
chapter_form.collection_select :chapter_type,
@decodes, :internal_value, :display_value, :prompt => 'Select module
type'
%>
</p>
<p>
<%= chapter_form.submit 'Create' %>
</p>
<% end %>
<%= link_to 'Back', chapters_path %>
Controller:
---------------
class ChaptersController < ApplicationController
def create
@chapter = Chapter.new(params[:chapter])
respond_to do |format|
if @chapter.save
flash[:notice] = 'Chapter was successfully created.'
format.html { redirect_to(@chapter) }
format.xml { render :xml => @chapter, :status
=> :created, :location => @chapter }
else
format.html { render :action => "new" }
format.xml { render :xml => @chapter.errors, :status
=> :unprocessable_entity }
end
end
end
end
Does anyone have an idea about the problem?
Thanks in advance,
Pratik
