Question

I am using rails 3.0.10 and ruby 1.9.2p0

In my rails app I am trying to validate my model through a “validates_uniqueness_of”

In my model(label) there is field named as “name” and I want to validate it as:

validates_uniqueness_of :name, :scope => [:portal_id], :on => :save

Portal is another model in my app.

It validates perfectly when i use :on => :create or :update individually, but fails when i use :on => :save

any idea I want to validate on save, but AR validation fails.

Answer 1

As default all validations run before save.so no need to give :on => :save

Simply use

validates_uniqueness_of :name, :scope => [:portal_id]
