Question

In my specs, when I run the POST request below, everything works fine.

    before do
      request_payload = {
        player: {
          first_name: "Joe",
          last_name: "Carradine",
          team_id: "1"
        }
      }

      post :create, request_payload
    end

But when I run a spec for PUT:

    before do
      request_payload = {
        player: {
          first_name: "Buck",
          last_name: "Carradine",
          team_id: "1"
        }
      }

      put :update, { id: 3 }, request_payload
    end

I get an error like this:

 Failure/Error: put :update, { id: 1 }, request_payload
 NoMethodError:
   undefined method `[]' for nil:NilClass

I can’t figure out what is being considered nil. This API call works fine in a REST client.

This is another error based on a previous SO question: Receiving error in RSpec for PUT, but not POST

Answer 1

You should do :

put :update, { id: 3 }.merge(request_payload)
