Rails g scaffold for module resource generates wrong directory in jbuilder templates.

[rafaelfranca]

From @jung-hunsoo on January 30, 2017 10:9

Steps to reproduce

$ rails g scaffold guest/category title description

Expected behavior

While many new files being generated, three jbuilder templates are expected to be created like this:

• _guest_category.json.jbuilder
  json.extract! guest_category, :id, :title, :description, :created_at, :updated_at
json.url guest_category_url(guest_category, format: :json)

• index.json.jbuilder
  json.array! @guest_categories, partial: 'guest/categories/guest_category', as: :guest_category

• show.json.jbuilder
  json.partial! "guest/categories/guest_category", guest_category: @guest_category

Actual behavior

The two jbuilder templates for index and show have inexistent directory which the module namespace isn't applied.

• _guest_category.json.jbuilder
  json.extract! guest_category, :id, :title, :description, :created_at, :updated_at
json.url guest_category_url(guest_category, format: :json)

• index.json.jbuilder
  json.array! @guest_categories, partial: 'guest_categories/guest_category', as: :guest_category

• show.json.jbuilder
  json.partial! "guest_categories/guest_category", guest_category: @guest_category

System configuration

Rails version: 5.0.1

Ruby version: 2.3.3

I just ran into this, looking to submit test + patches soon.

System configuration:

Rails version: 5.0.1

Ruby version: 2.3.1

Basically, using jbuilder from the rails point of view (rails 5.0.0 in api-mode afaik uses jbuilder by default, and in 5.0.0.1 you can enable it after you create the project) when invoking the rails generate scaffold command to create a resource under a namespace, view code is not correctly generated.

For example in my index.json.jbuilder which I got from a rails g scaffold api/oof rab:integer zab:string on a rails app that uses jbuilder I got out of the box as the file describing the index for all oofs app/views/api/oofs/index.json.jbuilder:

json.array! @api_oofs, partial: 'api_oofs/api_oof', as: :api_oof

...which breaks the app, since, for example, the partial really is in api/oofs/api_oof.json.jbuilder, not in api_oofs/api_oof.json, which is what the framework is assuming:

http localhost:3000/api/oofs

{
    "error": "Internal Server Error",
    "exception": "#<ActionView::Template::Error: Missing partial api_oofs/_api_oof with {:locale=>[:en], :formats=>[:json, :html, :text, :js, :css, :ics, :csv, :vcf, :png, :jpeg, :gif, :bmp, :tiff, :svg, :mpeg, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :pdf, :zip, :gzip], :variants=>[], :handlers=>[:jbuilder]}.

..........

This also affects the other locations that @rafaelfranca mentioned.

Changing the view code from api_oofs/api_oof.json to api/oofs/api_oof.json fixes the problem:
