ruby - Rails testing non-AR model(class) with FactoryGirl -

i have class looks this:

class killmail::parser   def initialize(body)     @body = body   end end 

i have factory it:

factorygirl.define   factory :parser, class: killmail::parser     skip_create      body '2013.12.02 19:24 bla bla'      initialize_with { new(attributes) }   end end 

it works fine long don't try change default attributes. when try use this

factorygirl.create(:parser, body: 'some different body') 

it returns this:

=> #<killmail::parser:0x007fb2ff116548 @body={:body=>"some different body"}> 

what doing wrong? can't google useful on case.

have tried calling new(body) instead of new(attributes)? problem lie how you're initializing parser class.

attributes creates hash of attributes , passes that...

initialize_with { new(attributes) } # translates parser.new({ body: '2013.12.02 19:24 bla bla' }) 

while calling #new body passes value first param...

initialize_with { new(body) } # translates parser.new('2013.12.02 19:24 bla bla') 

and can add many values #new want in same fashion...

# in factorygirl.define new_var_1 'new_string_1' new_var_2 2  initialize_with { new(body, new_var_1, new_var_2) } # translates parser.new('2013.12.02 19:24 bla bla', 'new_string_1', 2)
