klass.metaclass.class_eval
Reported by Yaraher | December 3rd, 2008 @ 08:56 PM
I'm currently trying Searchlogic but have find to have some issues making it work properly.
After installing it (either by using gem or plugin) it get this error when starting my server:
/Users/alvaropereyrarabanal/Development/SK/vendor/plugins/binarylogic-searchlogic/lib/
searchlogic/conditions/magic_methods.rb:8:in `included': undefined method `metaclass' for
Searchlogic::Conditions::Base:Class (NoMethodError)
which mentions this line:
def self.included(klass)
klass.metaclass.class_eval do
include ClassMethods
attr_accessor :added_column_equals_conditions, :added_associations
end
I tried changing the line to
def self.included(klass)
klass.class_eval do
include ClassMethods
attr_accessor :added_column_equals_conditions, :added_associations
end
and that seemed to at least let me run. However, when trying to search something with it, it can't find the added_associations from my product model (which is obviously something that must be added on the line I modified):
NoMethodError (undefined method `added_associations' for Searchlogic::Cache::ProductConditions:Class):
Is there something wrong I'm doing when trying to start Searchlogic?

- State changed from “new” to “resolved”
I'm assuming you are using an older version rails that doesn't have meta class. Update from the repository, it should work now. Let me know if you have any probs.

That did the trick. However, when trying to do a Product search, I get this error:

It looks like you found a old bug in ActiveRecord. Do you have a funny relationship or something? Because that is a bug had been fixed in later versions. Could you update to 2.1.2 at least? Because there is nothing I can do about that.

I'm currently working with 2.1.0. Will try updating then. Thanks!

Even on 2.2.2 (it was time to do it anyway) shows the

After playing with some of the relationships, I find out the one of them was worthless.
