RSpec undefined local variable or method

Question

Having a weird error in spec/controllers/profiles_controller_spec.rb: undefined local variable or method 'profile'

Pasted in relevant sections of the controller:

require 'rails_helper' require 'factory_girl' describe ProfilesController, :type => :controller do login_user #this is defined elsewhere, not an issue describe "PUT update" do before(:each) do @profile = FactoryGirl.create(:profile) end context "valid attributes" do it "located the requested @profile" do put :update, id: @profile, profile: FactoryGirl.attributes_for(:profile) assigns(:profile).should eq(@profile) end end end end

Can you paste the backtrace? "undefined local variable or method xyz" is a general ruby error when you have a bare word that doesn't reference a defined local variable or method. You don't have any such profile bare word in the spec you posted above, so it's probably coming from something you are calling from this spec. — Myron Marston

My guess is that there isn't a problem in your spec or your factory. The problem is with the controller you are testing.

The exception you see

1) ProfilesController PUT #update valid attributes located the requested @profile Failure/Error: put :update, id: @profile, profile: FactoryGirl.attributes_for(:profile) NameError: undefined local variable or method `profile' for #<ProfilesController:0x007fae343cfe08>

tells you that your ProfilesController has undefined local variable or method profile.

In your controller, you have this line

if @profile.update(profile)

that most likely causes the error. Perhaps you need need to change that update(profile) to update(profile_params)? This is hard to tell without seeing the whole controller, but that would follow a common pattern. And I guess you have a method profile_params that returns the filtered params.

Here's my profile controller: gist.github.com/maclover7/66ea65a9390c9f25521d

Have you defined a factory in test/factories.rb or spec/factories.rb?

It'll look something like this:

# This will guess the User class FactoryGirl.define do factory :user do first_name "John" last_name "Doe" admin false end # This will use the User class (Admin would have been guessed) factory :admin, class: User do first_name "Admin" last_name "User" admin true end end
