Bernard,
I've applied your technique but found a problem.
I'm using a context in a before :save hook, but there is no place
where this context is referenced prior, so I get an error that the
context isn't defined.
gems/dm-validations-0.9.8/lib/dm-validations/contextual_validators.rb
in `execute' - 43
43 raise(ArgumentError, 'invalid context specified') if !named_context
|| (contexts.length > 0 &&
my before hook looks like this:
before :save do | context |
case context
...
when :password_reset_request
...
end
end
To get around it, I added an unneeded validation:
validates_with_method :activated?, :when => [:password_reset_request]
I can think of three solutions:
1 - DM doesn't check for invalid contexts
2 - somehow, you figure out which contexts get defined in hooks
(probably too hard)
3 - need to expose a way to simply add a context without defining a
validator
I'm guessing option 3 is the way to go.
What do you think?
thanks, Jon
