Hi there, it's an afternoon that i'm destroying my head on this, and i've decided to ask to you all . I've got to do some check box lists for a modified substruct version i'm doing, right now, i'm interested to insert a list of categories of interests into a customer sheet i'm using the substruct plugin version, wich stays in the plugin/vendor version. the category.rb stays in the myapp/app/models , while the order_user.rb stays in myapp/vendor/plugins/substruct/app/models . this is my models class Category < ActiveRecord::Base has_and_belongs_to_many :order_users end class OrderUser < ActiveRecord::Base include CheckboxSelectable has_and_belongs_to_many :categories #many other things down below end this are my controller def updateCust @customer = OrderUser.find(params[:id]) @customer.update_attributes(params[:customer]) @customer.update_check_list(params, 'Category') if @customer.save flash[:notice] = 'Customer was successfully updated.' redirect_to :action => 'customers' else flash[:notice] = 'Something went wrong,please review your data' redirect_to :action => 'customers' end end and the view <%= checkbox_select('customer', 'categories', @categories, 'name') %> As you can see, i'm using the Checkbox select rails plugin ( http://scoop.cheerfactory.co.uk/2007/11/05/checkbo... ). I've already tried the version in the railscast (http://railscasts.com/episodes/17) but in both cases, the first time i try to load the page, i get this error: substruct_development.categories_order_users' doesn't exist: SELECT `categories`.id FROM `categories` INNER JOIN `categories_order_users` ON `categories`.id = `categories_order_users`.category_id , so i reload and all goes fine!ad the boxes too, they appears! but if i try to check a box and then to save a record, i get this error: ActiveRecord::AssociationTypeMismatch in Admin/usersController#updateCust Category(#18224400) expected, got Category(#18557480) or something similar, only numbers change! Now, AssociationTypeMismatch is when you want to cope wrong types of data together, but this is not the case :( what i've to do? please help me!
