Sometimes you want to create a table without an associated model and
test, which is also not a join table. With this commit, you can now
do that.
Example:
rails g migration create_posts title:string
or
rails g migration CreatePosts title:string
This commit also moves the template the model generator uses for the
migration to the migration templates folder, as it seems a more
sensible place for it now that it is shared code.
We discussed that the auto explain feature is rarely used.
This PR removes only the automatic explain. You can still display
the explain output for any given relation using `ActiveRecord::Relation#explain`.
As a side-effect this should also fix the connection problem during
asset compilation (#9385). The auto explain initializer in the `ActiveRecord::Railtie`
forced a connection.
When we removed script/rails and introduced bin/rails, we accidentally
introduced a regression. If you install Rails 4 as a gem, then try to do
something in a Rails 3 application:
$ rails g
This will throw the 'please type rails new foo' message rather than the
proper generator documentation message. This is because older apps don't
have bin/rails.
Therefore, we now *prefer* bin/rails, but still search for script/rails,
and exec the one we find.
Because of the possibility of lib being unintentionally eager loaded
it's been agreed that we'll leave autoload paths and eager load paths
separate for Rails 4.0.
This reverts commit 0757b3388ffe4f44b60de950d40e18ef05055931.
Conflicts:
railties/CHANGELOG.md
Print a message in both `rake routes` and at GET "/rails/info/routes"
that lets you know you have no routes defined, as well as linking to the
Rails Guide on the topic.
Since the default in Rails 4.0 is to run in 'threadsafe' mode we need
to eager load all of the paths in `autoload_paths` so we alias
`eager_load_paths` to it. This may have unintended consequences if
you have added 'lib' to `autoload_paths` such as loading unneeded
code or code intended only for development and/or test environments.
If this applies to your application you should thoroughly check what
is being eager loaded.
Historically serving assets from a mountable engine could be achieved by
running ActionDispatch::Static as a part of engine middleware stack or
to copy assets prefixed with an engine name. After introduction of
assets pipeline this is not needed as all of the assets are served or
compiled into main application's assets.
This commit removes the obsolete line making asset_path always generate
paths relative to the root or config.relative_url_root if it's set.
