undefined local variable or method 'session'

session variable is not available on Cell specs by design, or am I doing something wrong?

FYI @request.session seems to work, so maybe is just a shortcut missing or something

And it also seems I can't access the named routes. Here's a spec to demonstrate the issues I'm having:

require 'spec_helper'
describe HeaderCell do

  it "demonstrates that we have the correct modules included" do
    # This passes
    self.class.included_modules.should include(RSpec::Rails::CellExampleGroup)
    self.class.included_modules.should include(RSpec::Rails::CellExampleGroup::InstanceMethods)
  end

  it "should have access to named routes via the controller" do
    # This passes
    controller.help_path.should == '/help'
  end

  it "should have access to named routes directly from the example" do
    # This FAILS with:
    # (undefined local variable or method `help_path' for #<RSpec::Core::ExampleGroup::Nested_1:0x007fb137698120>)
    help_path.should == '/help'
  end

  it "should have access to the session variable via the request" do
    # This passes
    @request.session[:foo] = 'bar'
    @request.session[:foo].should == 'bar'
  end

  it "should have access to the session directly from the example" do
    # This FAILS with:
    # (undefined local variable or method `session' for #<RSpec::Core::ExampleGroup::Nested_1:0x007fb137666fd0>)
    session[:bar] = 'baz'
    session[:bar].should == 'baz'
  end

end

I just encountered this problem after upgrading rspec-rails from 0.0.5 to 0.1.1 .

Is there a workaround other than prefixing named routes with @request.?

[nickhoffman]

Bump

[PikachuEXE]

Still happens today
Is there a quick fix?

@PikachuEXE Please paste the complete stacktrace.

[apotonick]

Still an issue with 0.3?

[PikachuEXE]

Let me check next week

[PikachuEXE]

Can't check since I am unable to upgrade to cells 4 yet

[apotonick]

What keeps you from updating? I know the pain, my friend, we just upgraded an app to Rails 3.2 haha.

[PikachuEXE]

The app has too many "old" cells
Need to convert them all into concept cells first 😣

we just upgraded an app to Rails 3.2
Holy... world

[andricicezar]

I have this bug too. I try to sign_in a user if it is logged in with CASino and it tries to edit its account,.

class RegistrationsController < Devise::RegistrationsController
  include CASino::SessionsHelper

  before_action :ensure_signed_in, only: [:edit]
  skip_before_filter :authenticate_scope!, only: [:edit]

  def edit
    if current_user
      Class.new.extend(Devise::Controllers::Helpers).sign_in(:devise_users, DeviseUser.find(current_user.id))
    end

    super
  end
end

Your breaking spec file would be helpful to see. I have to warn you, though, I don't use Rspec and Devise so it might take a while.
