It's not really a good idea to have this as a global config option. We
should allow people to specify the behaviour per association.
There will now be two new values:
* :dependent => :restrict_with_exception implements the current
behaviour of :restrict. :restrict itself is deprecated in favour of
:restrict_with_exception.
* :dependent => :restrict_with_error implements the new behaviour - it
adds an error to the owner if there are dependent records present
See #4727 for the original discussion of this.
For instance, running
rails g migration CreateMediaJoinTable artists musics:uniq
will create a migration with
create_join_table :artists, :musics do |t|
# t.index [:artist_id, :music_id]
t.index [:music_id, :artist_id], unique: true
end
AddXXXToYYY/RemoveXXXFromYYY migrations are produced with references
statements, for instance
rails g migration AddReferencesToProducts user:references
supplier:references{polymorphic}
will generate the migration with:
add_reference :products, :user, index: true
add_reference :products, :supplier, polymorphic: true, index: true
For instance,
$ rails g model Product supplier:references{polymorphic}
generate model with `belongs_to :supplier, polymorphic: true` association and appropriate migration.
Also fix model_generator_test.rb#L196 and #L201
if we are passing -T which is skip_test_unit
See issue #6673 for more details.
I saw that we are not creating dummy app even if
we do skip_test_unit.
Fixes#6673
The Gemfile of new application uses ruby 1.9 hashes. Gem method of
generators should use them too. It prevents from mixing two kinds of
syntax in one file.
Using require in development mode will prevent required files from
reloading, even if they're changed. In order to keep namespaced
application_controller reloadable, we need to use require_dependency
instead of require.
In development mode, dependencies are loaded dynamically at runtime,
using `const_missing`. Because of that, when one of the constants is
already loaded and `const_missing` is not triggered, user can end up
with unexpected results.
Given such file in an Engine:
```ruby
module Blog
class PostsController < ApplicationController
end
end
```
If you load it first, before loading any application files, it will
correctly load `Blog::ApplicationController`, because second line will
hit `const_missing`. However if you load `ApplicationController` first,
the constant will be loaded already, `const_missing` hook will not be
fired and in result `PostsController` will inherit from
`ApplicationController` instead of `Blog::ApplicationController`.
Since it can't be fixed in `AS::Dependencies`, the easiest fix is to
just explicitly load application controller.

Reverted changes:
f3482a9 Fix tests in railties
5904295 improve #6318
aed906a prevent using already loaded Gemfile for 'bundle install'
In order to fix this, we need a fix in bundler related to GEM_PATH,
which will allow to run tests properly. I will get this changes back
when it happens.
Since `bundle install` was fixed in `rails plugin new`, it
now requires `rails 4.0.0.beta` version in filesystem when
running tests. Instead of providing it, we can run tested
command with `--dev` option, to use rails from the local
directory.
In case `source_roout` is not set, `default_source_root` is used,
which includes also `templates` directory. If there is no `templates`
directory, `default_source_root` is not available and USAGE will not
be displayed. USAGE should be also checked based on default
directory excluding `templates`.
