Fabricator of a model that has a column named `klass'

[irohiroki]

the snippet below spills an ArgumentError (wrong number of arguments (1 for 0)).

require 'fabrication'

class Foo
  attr_accessor :klass
end

Fabricator(:foo) do
  klass 'value'
end

is there any means to avoid that?

[irohiroki]

ah,

Fabricator(:foo) do
  after_build {|foo| foo.klass = 'value' }
end

works around the issue.
any brighter idea?

In the context of the Fabricator block, Ruby thinks you're referring to the klass attribute on Fabrication::Schematic, which is the constant Foo. The after_build works because you're able to specify the Foo class as your target.

I can't think of a better solution than yours, or to treat klass as a reserved word and not use it in this case. Perhaps @paulelliott will have better suggestions. :)

This is definitely a bug in fabrication. In the mean time, you can either use Matt's workaround with the after_build callback or name your attribute something else.

It seems there are a lot of methods that can collide when in the context of a Fabricator:
