[rspec-users] unable to access flash from rails helper spec since upgrade to 1.1.4

Hi,

Many moons ago I wrote this blog entry...

http://blog.wolfman.com/articles/2007/07/14/using-rspec-to-test-haml-helpers

I just upgraded that rails project to use rspec 1.1.4 and associated
rspec_rails.

It seems that my helper when called from the helper specs no longer are able to
access flash,
controller etc as they did before.

I already prepended all helper calls with helper. so I fixed those changes, but
I have been unable
to figure out how to access flash etc...

Here is a simplified example...

in ApplicationHelper.rb

  def test_flash
     for name in [:notice, :warning, :error]
       if flash[name]
         return "#{flash[name]}"
       end
     end
     nil
   end

In my rails/spec/helpers/application_helper_spec.rb

require File.dirname(__FILE__) + ''/../spec_helper''

describe ApplicationHelper do

   it "should test flash" do
     for name in [:notice, :warning, :error]
       flash[name]= "flash #{name.to_s} message"
       helper.test_flash.should match(/.*#{name}.*/)
       flash[name]= nil
     end
   end

end

I get this error trace...
1)
NoMethodError in ''ApplicationHelper should test flash''
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.[]
/.../app/helpers/application_helper.rb:23:in `test_flash''
...

flash is nil, this used to work, so what is the new magic incantation to get
this to work again?

Thanks

Hey Jim - I fixed this in
http://github.com/dchelimsky/rspec-rails/commit/40a0916325dbe9a1631849146d078e330fca71f2
, so you can either grab the very latest from github or wait for the  
1.1.5 release (coming in the next few days).

Cheers,
David

[rspec-users] unable to access flash from rails helper spec since upgrade to 1.1.4

Hi David,

Thanks that worked, and fixed that problem.

Now I have run into another problem, from the same blog example (which
I''ll update once I get it all
to work).

Within the application helper I call haml_tag, which works fine when the app
runs. (used to be
called open).

However when I try to test that helper in my helper spec I get...

NoMethodError in ''ApplicationHelper should display flash''
undefined method `haml_tag'' for
#<Spec::Rails::Example::HelperExampleGroup::HelperObject:0xb71ced20>

For some reason it doesn''t know anything about haml when run from the
spec.

I guess I need to inject a require haml or something into the HelperObject? I
just don''t know how to
do that.

I am using the latest version of HAML but I am still using rails 1.2.6

Any ideas?

Thanks
Jim

Try this:

before(:each) do
   helper.extend Haml::Helpers
end

it "should ...." do
   ...
end

[rspec-users] unable to access flash from rails helper spec since upgrade to 1.1.4

Ok, its messy but this works...

   before :each do
     init_haml_helpers
     helper.extend Haml
     helper.extend Haml::Helpers
     helper.send :init_haml_helpers
   end

   it "should display flash" do
     for name in [:notice, :warning, :error]
       flash[name]= "flash #{name.to_s} message"
       helper.capture_haml{
         helper.display_flash
       }.should match(/<div
class=''#{name.to_s}''>\s*#{flash[name]}\s*<\/div>/)
       flash[name]= nil
     end
   end

...

NOTE that the capture haml needs to be prepended by helper. otherwise nothing
gets returned.
