Here `app` needed to be `get` because we're getting a route. This fixes
the typo so the test passes.

Add missing routing tests for info controller

Added test case for deprecation of Mime.const_defined? and removed use of it

Fix proper fonts in `change_column_null` method docs. [ci skip]

Vaguely related to #21605 where I proposed to remove index route since it was redirecting to the 'routes' action,

but this was kept so I thought it made sense to add some tests regarding this.

[ci skip] Add `Active Model` to a list of independently used modules.

Added test cases where collection partial cached & rendered with different keys 

`inverse_of` on through associations was accidently removed/caused to
stop working in commit f8d2899d which was part of a refactoring on
`ThroughReflection`.

To fix we moved `inverse_of` and `check_validity_of_inverse!` to the
`AbstractReflection` so it's available to the `ThroughReflection`
without having to dup any methods. We then need to delegate `inverse_name`
method in `ThroughReflection`. `inverse_name` can't be moved to
`AbstractReflection` without moving methods that set the instance
variable `@automatic_inverse_of`.

This adds a test that ensures that `inverse_of` on a `ThroughReflection`
returns the correct class name, and the correct record for the inverse
relationship.

Fixes #21692

We only want to activate flash when the user has enabled it.  Api
servers don't use flash, so add an empty implementation to the base
Request object.

Committing the flash needs to happen in order for the session to be
written correctly, so lets guarantee that it actually does happen.

I'm doing this so that we can commit the flash to the session object Out
