undefined method `shift' for :authorization_rules:Symbol

[psjavi]

Hi, when I try to execute http://localhost:3000/authorization_rules I've got the error:

"undefined method `shift' for :authorization_rules:Symbol"

NoMethodError - undefined method shift' for :authorization_rules:Symbol: declarative_authorization (0.5.7) lib/declarative_authorization/development_support/analyzer.rb:212:inprocess_call'

I'm using Rails 4.0.0 and Ruby 1.9.3

It looks like the sexps generated by the ruby_parser gem are not in the expected format.

Hi, I've been debugging a little and these are the values ​​that have been taking from line 210 to line 212:

value of exp

exp = s(s(:hash, s(:lit, :to), s(:lit, :manage)))

arglist_line = exp[0].line

arglist_line = 14

arglist = process(exp.shift).shift

arglist = :array

context = arglist.shift

NoMethodError: undefined method `shift' for :array:Symbol

What's the expected format?

Thanks!!

I'm not sure how, but it looks like the DSL analyzer was acting up, which is strange because the authorization rules I had in my Rails 4 app were working fine for me. As far as I can tell this issue was not exclusive to Rails 4 though since there were a lot tests failing or with errors even when I ran the test suite in Rails 3.2 on ruby 1.9.3 and Rails 2.3 on 1.8.7. Everything seems to be working after the above commits though.

@stffn, is this fixed as part of the latest published gem? (doesn't seem like it as per rubygems 0.5.7 is the latest version which was published before this was fixed).

Thanks
