Callbacks?

[mockdeep]

I'm trying to write a dummy model to test that callbacks are used properly, but with_model throws an error:

NoMethodError:
  undefined method `_run_before_save_callbacks' for #<Dummy id: nil, created_at: nil, updated_at: nil>
# /home/fletch/.rvm/gems/ruby-2.1.7/gems/activemodel-4.2.4/lib/active_model/attribute_methods.rb:433:in `method_missing'
# /home/fletch/.rvm/gems/ruby-2.1.7/gems/activesupport-4.2.4/lib/active_support/callbacks.rb:81:in `run_callbacks'

I don't know if it's digging too deep into re-implementing the underlying details of ActiveRecord, but it would be nice to be able to use with_model to test callbacks as well.

Oops, I'm conflating a couple of things. That error is a known issue with active record.

But the other piece still stands, since I can't add before_save callbacks into with_model.

Please provide minimal failing example code.

with_model :Dummy do
  after_save -> { puts 'whatevs' }
  table(&:timestamps)
end

results in:

undefined method `after_save' for #<WithModel::Model::DSL:0x0000000a6a7728> (NoMethodError)

Did you mean to do:

with_model :Dummy do
  model do
    after_save -> { puts 'whatevs' }
  end
  table(&:timestamps)
end

Also the error with the code you give is different than your original error (though you did mention that that particular error was the result of an ActiveRecord bug, not the issue with with_model).

Ah, you are correct. My mistake.
