Relationships controller for creating an ajax relationship -NoMethodError: undefined method `[model]


I believe I am having problems with the redirect_to in my controller below. A course has many levels, which has many steps (step belongs to level, and level belongs to course). I am trying to redirect_to the step.

Here is my route for a step:


Here is my error in the controller:

Failure/Error: click_button "check answer" NoMethodError: undefined method `step_url' for #<UserStepsController:0x007ff8ccc478c8>

Here is the controller in which the error occurs:

class UserStepsController < ApplicationController before_filter :authenticate_user! def create @step = Step.find(params[:user_step][:step_id]) current_user.attempt_step!(@step) respond_to do |format| format.html { redirect_to @step } format.js end end def destroy @step = UserStep.find(params[:id]).step current_user.remove_user_step!(@step) respond_to do |format| format.html { redirect_to @step } format.js end end end

Here is the rspec

describe "attempting a step" do let(:course) { FactoryGirl.create(:course)} let(:level) { FactoryGirl.create(:level, course: course) } let(:step) { FactoryGirl.create(:step, level: level) } before { sign_in user} describe "taking a course" do before { visit course_level_step_path(course.id, level.id, step.id)} it "should increment the user step count" do expect do click_button "check answer" end.to change(user.user_steps, :count).by(1) end describe "toggling the button" do before { click_button "check answer"} it { should have_selector('input', value: 'remove step')} end end


You can't use redirect_to @variable when you have nested resources. The correct way would be for you to say

redirect_to course_level_step_url(@step.level.course.id, @step.level.id, @step.id)

Because the thing that gets the route from the instance variable 'thinks' you want the path of the lowercased class name plus _url
