When an application has multiple root entries with different
constraints, the current solution is to use `get '/'`. Example:
**Currently I have to do:**
```ruby
get '/', to: 'portfolio#show', constraints: ->(req) { Hostname.portfolio_site?(req.host) }
get '/', to: 'blog#show', constraints: ->(req) { Hostname.blog_site?(req.host) }
root 'landing#show'
```
**But I would like to do:**
```ruby
root 'portfolio#show', constraints: ->(req) { Hostname.portfolio_site?(req.host) }
root 'blog#show', constraints: ->(req) { Hostname.blog_site?(req.host) }
root 'landing#show'
```
Other URL matchers such as `get`, `post`, etc, already allows this, so I
think it's fair that `root` also allow it since it's just a shortcut for
a `get` internally.
With the previous implementation, the block passed to
define_singleton_method, which will live forever as the method body,
captures the parameters (args and block) in its enclosure.
For the current_scope registry, that can include an AR::Relation.
Adds a paragraph to the documentation of the `ActiveRecord::Scoping::Named.scope` method,
explaining that the method is intended to return an ActiveRecord::Relation object to be
composable with other scopes.
In the case that in the case that `nil` or `false` are returned, the method returns
an `all` relation instead.
This unexpected behaviour is mentioned in #19249#14256#21465 and #21882 and wasn't
documented at all. This commit adds this documentation.
Saw this while doing a review of a patch:
* Normalize case and punctuation across comments.
* ascii -> ASCII
* Since I was on it, some blank lines that visually
add some clarity IMO.
We'd see the failures and errors reported after the run, which is needless, when we've already
reported them.

`pk_and_sequence_for` is implemented for PG and MySQL adapters (not
implemented for Sqlite3 adapter). But MySQL adapters are not using
`pk_and_sequence_for` already.
When generating the url for a mounted engine through its proxy, the path should be the sum of three parts:
1. Any `SCRIPT_NAME` request header or the value of `ActionDispatch::Routing::RouteSet#relative_url_root`.
2. A prefix (the engine's mounted path).
3. The path of the named route inside the engine.
Since commit 44ff0313c1, this has been broken. Step 2 has been changed to:
2. A prefix (the value of `ActionDispatch::Routing::RouteSet#relative_url_root` + the engine's mounted path).
The value of `ActionDispatch::Routing::RouteSet#relative_url_root` is taken into account in step 1 of the route generation and should be ignored when generating the mounted engine's prefix in step 2.
This commit fixes the regression by having `ActionDispatch::Routing::RouteSet#url_for` check `options[:relative_url_root]` before falling back to `ActionDispatch::Routing::RouteSet#relative_url_root`. The prefix generating code then sets `options[:relative_url_root]` to an empty string. This empty string is used instead of `ActionDispatch::Routing::RouteSet#relative_url_root` and avoids the duplicate `relative_url_root` value in the final result.
This resolves#20920 and resolves#21459
