rspec users - Apr 2011 - difference between validate and validate_on_create

i just ran into a problem with some test, and i am not exactly sure why,
but the difference happened when i changed my model validation from:

validate :custom_validation

to:

validate_on_create :custom_validation

can someone give me any ideas on where in the chain the validation takes
place?

thanks!

`validate` will run that validation on create *and* update.
`validate_on_create` will only run on creation.

This is really a Rails or ActiveRecord question rather than RSpec.

In any case.

validate :custom_validation
  will run the custom_validation method whether the model is being
created or updated.

validate_on_create :custom_validation
  will only run the custom_validation method when the method is being created.

There''s also a validate_on_update method which will run the custom
validation method when the model is being updated but not when it is
created.
