Since #29504, mysql2 adapter lost ability to insert zero value on
primary key due to enforce `NO_AUTO_VALUE_ON_ZERO` disabled.
That is for using `DEFAULT` on auto increment column, but we can use
`NULL` instead in that case.

|

It was unused since 9e4c41c903e8e58721f2c41776a8c60ddba7a0a9.

Otherwise it will occur syntax error if primary key is a reserved word.

Improves the performance from O(n) to O(1).
Previously it would require 50 queries to
insert 50 fixtures. Now it takes only one query.
Disabled on sqlite which doesn't support multiple inserts.

Right now, when fixture is not a Hash we throw an error message
saying "fixture is not a hash". This is not very user friendly because
it's not saying which fixture is invalid.

If using namespaced fixtures, get following Ruby warning.
```

activerecord/lib/active_record/fixtures.rb:922: warning: previous definition of admin_foos was here

This is happening because of the multiple set the same path when setting the
fixture name. Fix to remove the duplicate path.

different types.
When passing in an array of different types of objects to `where`, it would only take into account the class of the first object in the array.
PriceEstimate.where(estimate_of: [Treasure.find(1), Car.find(2)])
# => SELECT "price_estimates".* FROM "price_estimates"
WHERE ("price_estimates"."estimate_of_type" = 'Treasure' AND "price_estimates"."estimate_of_id" IN (1, 2))
This is fixed to properly look for any records matching both type and id:
PriceEstimate.where(estimate_of: [Treasure.find(1), Car.find(2)])
# => SELECT "price_estimates".* FROM "price_estimates"
WHERE (("price_estimates"."estimate_of_type" = 'Treasure' AND "price_estimates"."estimate_of_id" = 1)
OR ("price_estimates"."estimate_of_type" = 'Car' AND "price_estimates"."estimate_of_id" = 2))

Add support for bidirectional destroy dependencies

Prior to this commit if you defined a bidirectional relationship
between two models with destroy dependencies on both sides, a call to
`destroy` would result in an infinite callback loop.
Take the following relationship.
class Content < ActiveRecord::Base
has_one :content_position, dependent: :destroy
end
class ContentPosition < ActiveRecord::Base
belongs_to :content, dependent: :destroy
end
Calling `Content#destroy` or `ContentPosition#destroy` would result in
an infinite callback loop.
This commit changes the behaviour of `ActiveRecord::Callbacks#destroy`
so that it guards against subsequent callbacks.
Thanks to @zetter for demonstrating the issue with failing tests[1].

Currently, `set_fixture_class` is only available using the
`TestFixtures` concern and it is ignored for `rake db:fixtures:load`.
Using the correct model class, it is possible for the fixture load
to also load the associations from the YAML files (e.g., `:belongs_to`
and `:has_many`).

After 908cfef was introduced fixtures that did not set an enum would
return nil instead of the default enum value.
The fixtures should assume the default if a different enum is not
defined.
The change checks first if the enum is defined in the fixture before
setting it based on the fixture.

Currently, values for columns backing Active Record enums must be
specified as integers in test fixtures:
awdr:
title: "Agile Web Development with Rails"
status: 2
rfr:
title: "Ruby for Rails"
status: <%= Book.statuses[:proposed] %>
This is potentially confusing, since enum values are typically
specified as symbols or strings in application code. To resolve the
confusion, this change permits the use of symbols or strings to specify
enum values:
awdr:
status: :published
It is compatible with fixtures that specify enum values as integers.

- Fixtures with non-string labels such as integers should be accessed
using integer label as key. For eg. pirates(1) or pirates(42).
- But this results in NotFound error because the label is converted into string before
looking up into the fixtures hash.
- After this commit, the label is converted into string only if its a
symbol.
- This issue was fount out while adding a test case for
https://github.com/rails/rails/commit/7b910917.

Prior to this patch you'd end up with an error like:
```
ActiveRecord::RecordNotFound: Couldn't find <Model> with 'id'=<id> [WHERE (<default_scope condition>)]
```

`User.where(id: [[1,2],3])` was equal to `User.where(id:[1, 2, 3])`
in Rails 4.1.x but because of some refactoring in Arel this stopped
working in 4.2.0. This fixes it in Rails.

The name of the foreign key is not relevant from a users perspective.
Using random names resolves the urge to rename the foreign key when the

Reliant on https://github.com/rails/rails/pull/15747 but pulled to a
separate PR to reduce noise. `has_many :through` associations have the
undocumented behavior of automatically detecting counter caches.
However, the way in which it does so is inconsistent with counter caches
everywhere else, and doesn't actually work consistently.
As with normal `has_many` associations, the user should specify the
counter cache on the `belongs_to`, if they'd like it updated.

Topics call `serialize :content`, which means that the values in the

This bug can be triggered when serializing record R (the instance) of type C
(the class), provided that the following conditions are met:
1. The name of one or more columns/attributes on C/R matches an existing private
method on C (e.g. those defined by `Kernel`, such as `format`).
2. The attribute methods have not yet been generated on C.
In this case, the matching private methods will be called by the serialization
code (with no arguments) and their return values will be serialized instead. If
the method requires one or more arguments, it will result in an `ArgumentError`.
This regression is introduced in d1316bb.
* * *
Attribute methods (e.g. `#name` and `#format`, assuming the class has columns
named `name` and `format` in its database table) are lazily defined. Instead of
defining them when a the class is defined (e.g. in the `inherited` hook on
`ActiveRecord::Base`), this operation is deferred until they are first accessed.
The reason behind this is that is defining those methods requires knowing what
columns are defined on the database table, which usually requires a round-trip
to the database. Deferring their definition until the last-possible moment helps
reducing unnessary work, especially in development mode where classes are
redefined and throw away between requests.
Typically, when an attribute is first accessed (e.g. `a_book.format`), it will
fire the `method_missing` hook on the class, which triggers the definition of
the attribute methods. This even works for methods like `format`, because
calling a private method with an explicit receiver will also trigger that hook.
Unfortunately, `read_attribute_for_serialization` is simply an alias to `send`,
which does not respect method visibility. As a result, when serializing a record
with those conflicting attributes, the `method_missing` is not fired, and as a
result the attribute methods are not defined one would expected.
Before d1316bb, this is negated by the fact that calling the `run_callbacks`
method will also trigger a call to `respond_to?`, which is another trigger point
for the class to define its attribute methods. Therefore, when Active Record
tries to run the `after_find` callbacks, it will also define all the attribute
methods thus masking the problem.
* * *
The proper fix for this problem is probably to restrict `read_attribute_for_serialization`
to call public methods only (i.e. alias `read_attribute_for_serialization` to
`public_send` instead of `send`). This however would be quite risky to change
in a patch release and would probably require a full deprecation cycle.
Another approach would be to override `read_attribute_for_serialization` inside
Active Record to force the definition of attribute methods:
def read_attribute_for_serialization(attribute)
self.class.define_attribute_methods
send(attribute)
end
Unfortunately, this is quite likely going to cause a performance degradation.
This patch therefore restores the behaviour from the 4-0-stable branch by
explicitly forcing the class to define its attribute methods in a similar spot
(when records are initialized). This should not cause any extra roundtrips to
the database because the `@columns` should already be cached on the class.
Fixes #15188.

Changed the call to a scope block to be evaluated with instance_eval.
The result is that ScopeRegistry can use the actual class instead of base_class when
caching scopes so queries made by classes with a common ancestor won't leak scopes.

conflicting private method defined on its ancestors.
The problem is that `method_defined_within?(name, klass, superklass)`
only works correclty when `klass` and `superklass` are both `Class`es.
If both `klass` and `superklass` are both `Class`es, they share the
same inheritance chain, so if a method is defined on `klass` but not
`superklass`, this method must be introduced at some point between
`klass` and `superklass`.
This does not work when `superklass` is a `Module`. A `Module`'s
inheritance chain contains just itself. So if a method is defined on
`klass` but not on `superklass`, the method could still be defined
somewhere upstream, e.g. in `Object`.
This fix works by avoiding calling `method_defined_within?` with a
module while still fufilling the requirement (checking that the
method is defined withing `superclass` but not is not a generated
attribute method).
4d8ee288 is likely an attempted partial fix for this problem. This
unrolls that fix and properly check the `superclass` as intended.
Fixes #11569.

This commit bring the famous ordinal Array instance methods defined
in ActiveSupport into ActiveRecord as fully-fledged finders.
These finders ensure a default ascending order of the table's primary
key, and utilize the OFFSET SQL verb to locate the user's desired
record. If an offset is defined in the query, calling #second adds
to the offset to get the actual desired record.
