_task.json.jbuilder has invalid arguments for project_task_url

[JunichiIto]

A reader of the Japanese edition found that _task.json.jbuilder has invalid arguments for project_task_url.

everydayrails-rspec-2017/app/views/tasks/_task.json.jbuilder

Line 2 in 90b2253

json.url project_task_url([task.project, task], format: :json)

It should be:

json.url project_task_url(task.project, task, format: :json)

The current test fails if tasks_controller_spec.rb has render_views views option:

 require 'rails_helper'
 
 RSpec.describe TasksController, type: :controller do
+  render_views
   include_context "project setup"

Failures:

  1) TasksController#create responds with JSON formatted output
     Failure/Error: json.url project_task_url([task.project, task], format: :json)

Thank you for reporting this. I think I'm going to keep this issue open for others who may find it, but leave it unfixed for now. Due to the branching strategy I took for building out each chapter's source code changes, I have to apply the change to each branch and handle several merge conflicts as I go. This adds risk to breaking the sample code, especially in later chapters.
