Hello
I have 2 models.
link.rb
has_many :categories, :as => :categorized
validates_presence_of :name, :url, :created_at, :category
category.rb
belongs_to :categorized, :polymorphic => true
validates_presence_of :name
Everything seems to work. I select my category from a select tag. The
problem is i don''t know how to validate if category is for example
empty
(nothing in a select tag), i would like to display the validation error
along with other validation errors for link.
My create link controller.
def create
@link = Link.new(params[:link])
if @link.save
flash[:notice] = ''Link was successfully created.''
category = Category.new(params[:category][:id])
category.categorized = @link
category.save
else
render :action => "new"
end
end

Perhaps try enclosing the ''save'' into a begin/rescue block?
I have something similar:
class Keyword < ActiveRecord::Base
has_many :rules, :order => :position
<-->
keywords_controller:
def addrule
@keyword = Keyword.find(params[:id])
rule_description = params[:rule][:description].strip
# exclamation mark after create method call forces validation
begin @keyword.rules.create!(:description => rule_description)
flash[:notice] = "New rule was successfully added."
rescue Exception
flash[:notice] = "Error saving rule: " + rule_description +
"<br/>"
flash[:notice] << $!.message
end
redirect_to :action => ''show'', :id => @keyword
end
