* Add fail fast to `bin/rails test`
Adding `--fail-fast` or `-f` when running tests will interrupt the run on
the first failure:
```
# Running:
................................................S......E
ArgumentError: Wups! Bet you didn't expect this!
test/models/bunny_test.rb:19:in `block in <class:BunnyTest>'
bin/rails test test/models/bunny_test.rb:18
....................................F
This failed
bin/rails test test/models/bunny_test.rb:14
Interrupted. Exiting...
Finished in 0.051427s, 1808.3872 runs/s, 1769.4972 assertions/s.
```
Note that any unexpected errors don't abort the run.
*Kasper Timm Hansen*
* Add inline output to `bin/rails test`
Any failures or errors (and skips if running in verbose mode) are output
during a test run:
```
# Running:
.....S..........................................F
This failed
bin/rails test test/models/bunny_test.rb:14
.................................E
ArgumentError: Wups! Bet you didn't expect this!
test/models/bunny_test.rb:19:in `block in <class:BunnyTest>'
bin/rails test test/models/bunny_test.rb:18
....................
Finished in 0.069708s, 1477.6019 runs/s, 1448.9106 assertions/s.
```
Output can be deferred to after a run with the `--defer-output` option.
*Kasper Timm Hansen*
* Fix displaying mailer previews on non local requests when config
`action_mailer.show_previews` is set
*Wojciech Wnętrzak*
* `rails server` will now honour the `PORT` environment variable
*David Cornu*
* Plugins generated using `rails plugin new` are now generated with the
version number set to 0.1.0.
*Daniel Morris*
* `I18n.load_path` is now reloaded under development so there's no need to
restart the server to make new locale files available. Also, I18n will no
longer raise for deleted locale files.
*Kir Shatrov*
* Add `bin/update` script to update development environment automatically.
*Mehmet Emin İNAÇ*
* Fix STATS_DIRECTORIES already defined warning when running rake from within
the top level directory of an engine that has a test app.
Fixes #20510
*Ersin Akinci*
* Make enabling or disabling caching in development mode possible with
rake dev:cache.
Running rake dev:cache will create or remove tmp/caching-dev.txt. When this
file exists config.action_controller.perform_caching will be set to true in
config/environments/development.rb.
Additionally, a server can be started with either --dev-caching or
--no-dev-caching included to toggle caching on startup.
*Jussi Mertanen*, *Chuck Callebs*
* Add a `--api` option in order to generate plugins that can be added
inside an API application.
*Robin Dupret*
* Fix `NoMethodError` when generating a scaffold inside a full engine.
*Yuji Yaginuma*
* Adding support for passing a block to the `add_source` action of a custom generator
*Mike Dalton*, *Hirofumi Wakasugi*
* `assert_file` understands paths with special characters
(eg. `v0.1.4~alpha+nightly`).
*Diego Carrion*
* Remove ContentLength middleware from the defaults. If you want it, just
add it as a middleware in your config.
*Egg McMuffin*
* Make it possible to customize the executable inside rerun snippets.
*Yves Senn*
* Add support for API only apps.
Middleware stack was slimmed down and it has only the needed
middleware for API apps & generators generates the right files,
folders and configurations.
*Santiago Pastorino & Jorge Bejar*
* Make generated scaffold functional tests work inside engines.
*Yuji Yaginuma*
* Generator a `.keep` file in the `tmp` folder by default as many scripts
assume the existence of this folder and most would fail if it is absent.
See #20299.
*Yoong Kang Lim*, *Sunny Juneja*
* `config.static_index` configures directory `index.html` filename
Set `config.static_index` to serve a static directory index file not named
`index`. E.g. to serve `main.html` instead of `index.html` for directory
requests, set `config.static_index` to `"main"`.
*Eliot Sykes*
* `bin/setup` uses built-in rake tasks (`log:clear`, `tmp:clear`).
*Mohnish Thallavajhula*
* Fix mailer previews with attachments by using the mail gem's own API to
locate the first part of the correct mime type.
Fixes #14435.
*Andrew White*
* Remove sqlite support from `rails dbconsole`.
*Andrew White*
* Rename `railties/bin` to `railties/exe` to match the new Bundler executables
convention.
*Islam Wazery*
* Print `bundle install` output in `rails new` as soon as it's available.
Running `rails new` will now print the output of `bundle install` as
it is available, instead of waiting until all gems finish installing.
*Max Holder*
* Respect `pluralize_table_names` when generating fixture file.
Fixes #19519.
*Yuji Yaginuma*
* Add a new-line to the end of route method generated code.
We need to add a `\n`, because we cannot have two routes
in the same line.
*arthurnn*
* Add `rake initializers`.
This task prints out all defined initializers in the order they are invoked
by Rails. This is helpful for debugging issues related to the initialization
process.
*Naoto Kaneko*
* Created rake restart task. Restarts your Rails app by touching the
`tmp/restart.txt`.
Fixes #18876.
*Hyonjee Joo*
* Add `config/initializers/active_record_belongs_to_required_by_default.rb`.
Newly generated Rails apps have a new initializer called
`active_record_belongs_to_required_by_default.rb` which sets the value of
the configuration option `config.active_record.belongs_to_required_by_default`
to `true` when ActiveRecord is not skipped.
As a result, new Rails apps require `belongs_to` association on model
to be valid.
This initializer is *not* added when running `rake rails:update`, so
old apps ported to Rails 5 will work without any change.
*Josef Šimánek*
* `delete` operations in configurations are run last in order to eliminate
'No such middleware' errors when `insert_before` or `insert_after` are added
after the `delete` operation for the middleware being deleted.
Fixes #16433.
*Guo Xiang Tan*
* Newly generated applications get a `README.md` in Markdown.
*Xavier Noria*
* Remove the documentation tasks `doc:app`, `doc:rails`, and `doc:guides`.
*Xavier Noria*
* Force generated routes to be inserted into `config/routes.rb`.
*Andrew White*
* Don't remove all line endings from `config/routes.rb` when revoking scaffold.
Fixes #15913.
*Andrew White*
* Rename `--skip-test-unit` option to `--skip-test` in app generator
*Melanie Gilman*
* Add the `method_source` gem to the default Gemfile for apps.
*Sean Griffin*
* Drop old test locations from `rake stats`:
- test/functional
- test/unit
*Ravil Bayramgalin*
* Update `rake stats` to correctly count declarative tests
as methods in `_test.rb` files.
*Ravil Bayramgalin*
* Remove deprecated `test:all` and `test:all:db` tasks.
*Rafael Mendonça França*
* Remove deprecated `Rails::Rack::LogTailer`.
*Rafael Mendonça França*
* Remove deprecated `RAILS_CACHE` constant.
*Rafael Mendonça França*
* Remove deprecated `serve_static_assets` configuration.
*Rafael Mendonça França*
* Use local variables in `_form.html.erb` partial generated by scaffold.
*Andrew Kozlov*
* Add `config/initializers/callback_terminator.rb`.
Newly generated Rails apps have a new initializer called
`callback_terminator.rb` which sets the value of the configuration option
`ActiveSupport.halt_callback_chains_on_return_false` to `false`.
As a result, new Rails apps do not halt Active Record and Active Model
callback chains when a callback returns `false`; only when they are
explicitly halted with `throw(:abort)`.
The terminator is *not* added when running `rake rails:update`, so returning
`false` will still work on old apps ported to Rails 5, displaying a
deprecation warning to prompt users to update their code to the new syntax.
*claudiob*
* Generated fixtures won't use the id when generated with references attributes.
*Pablo Olmos de Aguilera Corradini*
* Add `--skip-action-mailer` option to the app generator.
*claudiob*
* Autoload any second level directories called `app/*/concerns`.
*Alex Robbin*
