Fixed a bug in  when using has_many association with :inverse_of option and UUID primary key.
Adding documentation to +polymorphic_url+
concerning the options that it inherits from +url_for+. The way that
+polymorhpic_url+ is built allows it to have options
like +:anchor+, +:script_name+, etc. but this is currently not
documented.
Raising an error when nil or non-hash is passed to update_attributes.
Fix typo.
Migration dump UUID default functions to schema.rb. Fixes #10751.
Disable ability to iterate over a Range of TimeWithZone
let the sqlite task run without rails
Creating options for schema dumper.

These options make it easier to change the config from
ActiveRecord::Base to use something else inside of the SchemaDumper.
Rewrite journey routes formatter for performance
Small refactoring changes to generators.

Made a method name clearer (added a bang to the end to show that it
mutates arguments) and extracted indentation into its own method.
Pull the RelationMutationTests from cases/relation_test to cases/relation/mutation_test.
Deprecate the delegation of Array bang methods in ActiveRecord::Delegation

The primary means of returning results for Array bang methods is to modify
the array in-place. When you call these methods on a relation, that
array is created, modified, and then thrown away. Only the secondary
return value is exposed to the caller.

Removing this delegation is a straight-forward way to reduce user error
by forcing callers to first explicitly call #to_a in order to expose
the array to be acted on by the bang method.
do not break params filtering on nil values

closes #12149
Allow Relation#from to accept other relations with bind values.
form_for - fix :namespace and :as options clash

:as option should not overwrite :namespace option when
generating html id attribute of the form element. id should be prefixed
by specified namespace even if :as option is present

Add test case showing the issue and code fixing it
[ci skip] Add missing setting locale code snippet.

This is for 3 Internationalizing your Application of i18n.md.

Missing the code as mentioned in 2.3, setting locale.

Without this, the example to add config/locales/pirate.yml will not work.
[ci skip] Fix links in section 5.3 of i18n.md

Now all links point to the correct line number.
Make CollectionAssociation first/last with integer fetch with query

When first or last is called with an integer on an unloaded association,
the entire collection is loaded. This differs surprisingly from the
behavior of Relation#first/last, which translate the call into a limit
query. For large collections this can make a big difference in
performance.

Change CollectionAssociation#fetch_first_or_last_using_find? to make
this kind of call delegate to Relation.
[ci skip] Documentation on how to create custom rake tasks.
