This week's Rails contributors

This week we have 30 awesome contributors who helped improve Rails. Give them a hug when you run into them next time!

Showing off

Teasing aside, this is definitely a good Ruby trick/idiom to pick up!                                                                                                    

`after_bundle` callback in Rails templates

This pull request introduces a new hook for use in Rails application templates. The block passed to this callback method will be executed after the bundle as well as after the binstubs are generated, allowing you to further customize the result of those steps to your liking.

Automatically maintain test DB schema (again)

This feature was introduced in Rails 4.1. Unfortunately it does not work with structure.sql due to a bug in the implementation. The previous patch that addressed the issue was temporarily reverted due to another bug it introduced. This pull request is the latest attempt to address all these issue once and for all – hopefully we got it right this time!

Using `defined?` in view templates

Previously, the documentation suggested that you need to jump through some hoops to check if a local variable has been defined. Apparently, this is no longer necessary and you can simply do that with the Ruby Way™ using defined?.

Weak ETags in Rack master

A recent change in Rack was causing our builds to fail. With this change, Rack will generate "weak" ETag validators going forward. Check out the original issue and this wikipedia entry to learn more about this change.

Fixed updating custom primary keys

If you have to interface with legacy databases that uses custom primary key formats, this patch would allow you to update the value of these primary keys correctly.

Blank passwords and `has_secure_password`

Previously, an implementation issue was causing has_secure_password to (incorrectly) reject blank passwords (i.e. spaces only) without any feedback for the user. This has now been fixed on master. If you would like to block users from using these passwords, you might want to add some extra validation rules for your application going forward.

Rename `MiniTest` to `Minitest`

According to the package maintainer Ryan Davis, Minitest is now the canonical spelling for the accessing the constant. If your application or your gems have references to the old MiniTest constant (now an alias), now would be a good time to start switching them over!
