Hi
I`m trying to test my controller with rspec and always get an error.
The error is in the render_to_string method call (without it test
works fine). So could u please help me with that?

users_controller.rb:

def update
    @user.update_attributes!(params[:user])

    redirect_to @user, :status => 202, :text =>
render_to_string(:partial => "users/show", :type => "json", :locals =>
{:user => @user})
    #notice, that redirect_to was reinitialized and :text is a
parameter for response_body
end

_show.tokamak
user {
  id user.id
  email user.email
  username user.username
}
spec file
it "should NOT update user username" do
      username = @user.username
      put 'update', :id => @user.id, :user => {:username => username
+"abc"}, :format => :json
      response.status.should be(202)
      response.headers["Location"].length.should be > 0
      puts response.body
      @user.reload
      @user.username.should eq(username)
      end
    end
So I get an error:

Failure/Error: put 'update', :id => @user.id, :user => {:username =>
username+"abc"}, :format => :json ActionView::Template::Error: 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.[] # C:/

:in

Users/makaroni4/XXX/XXX/app/controllers/users_controller.rb:22:in
update' # ./users_controller_spec.rb:34:in `block (4 levels) in '

So may be I call render_to_string method wrong?
