Add :allow_nil option to delegate_missing_to; use in ActiveStorage attachment
2018-07-26 05:04:34 +08:00
* `delegate_missing_to` would raise a `DelegationError` if the object
delegated to was `nil`. Now the `allow_nil` option has been added to enable
the user to specify they want `nil` returned in this case.

Frozen truncate (#36109) * Add test asserting truncate returns unfrozen string * Ensure strings returned from truncate are not frozen This fixes an issue where strings too short to be truncated were returned unfrozen, where as long-enough strings were returned frozen. Now retuned strings will not be frozen whether or not the string returned was shortened. * Update changelog w/ new truncate behavior description [Jordan Thomas + Rafael Mendonça França]

* `truncate` would return the original string if it was too short to be truncated
and a frozen string if it were long enough to be truncated. Now truncate will
consistently return an unfrozen string regardless. This behavior is consistent
with `gsub` and `strip`.
Introduce Actionable Errors Actionable errors let's you dispatch actions from Rails' error pages. This can help you save time if you have a clear action for the resolution of common development errors. The de-facto example are pending migrations. Every time pending migrations are found, a middleware raises an error. With actionable errors, you can run the migrations right from the error page. Other examples include Rails plugins that need to run a rake task to setup themselves. They can now raise actionable errors to run the setup straight from the error pages. Here is how to define an actionable error: ```ruby class PendingMigrationError < MigrationError #:nodoc: include ActiveSupport::ActionableError action "Run pending migrations" do ActiveRecord::Tasks::DatabaseTasks.migrate end end ``` To make an error actionable, include the `ActiveSupport::ActionableError` module and invoke the `action` class macro to define the action. An action needs a name and a procedure to execute. The name is shown as the name of a button on the error pages. Once clicked, it will invoke the given procedure.
