This reverts commit 6d5b1fdf55611de2a1071c37544933bb588ae88e.
`eager_load` and `references` can include hashes, which won't match up
with `references`
A test case has been added to demonstrate the problem
When passing an instance of `ActiveRecord::Base` to `#update`, it would
internally call `#find`, resulting in a misleading deprecation warning.
This change gives this deprecated use of `#update` its own, meaningful
warning.
When preload is used in a default scope the preload_values were
returning nested arrays and causing the preloader to fail because it
doesn't know how to deal with nested arrays. So before calling preload!
we need to splat the arguments.
This is not needed to includes because it flatten its arguments.
Couldn't find other way to get the association name from a given class
other than looping through `reflect_on_all_associations` reflections ..
Noticed this one while looking at this example:
```ruby
class Product < ActiveRecord::Base
has_many :variants
has_many :translations
end
class Translation < ActiveRecord::Base
belongs_to :product
end
class Variant < ActiveRecord::Base
belongs_to :product
end
class BugTest < Minitest::Test
def test_merge_stuff
product = Product.create! name: 'huhu'
variant = Variant.create! product_id: product.id
Translation.create! locale: 'en', product_id: product.id
product_relation = Product.all
.preload(:translations)
.joins(:translations)
.merge(Translation.where(locale: 'en'))
.where(name: 'huhu')
assert_equal variant, Variant.joins(:product).merge(product_relation).first
end
end
```
See #9683 for the reasons we switched to `distinct`.
Here is the discussion that triggered the actual deprecation #20198.
`uniq`, `uniq!` and `uniq_value` are still around.
They will be removed in the next minor release after Rails 5.
Use SQL COUNT and LIMIT 1 queries for none? and one? methods if no block or limit is given,
instead of loading the entire collection to memory. The any? and many? methods already
follow this behavior.

`bound_attributes` is now used universally across the board, removing
the need for the conversion layer. These changes are mostly mechanical,
with the exception of the log subscriber. Additional, we had to
implement `hash` on the attribute objects, so they could be used as a
key for query caching.
The column is primarily used for type casting, which we're trying to
separate from the idea of a column. Since what we really need is the
combination of a name, type, and value, let's use the object that we
already have to represent that concept, rather than this tuple. No
consumers of the bind values have been changed, only the producers
(outside of tests which care too much about internals). This is
*finally* possible since the bind values are now produced from a
reasonable number of lcoations.
This fixed an issue where `having` can only be called after the last
call to `where`, because it messes with the same `bind_values` array.
With this change, the two can be called as many times as needed, in any
order, and the final query will be correct. However, once something
assigns `bind_values`, that stops. This is because we have to move all
of the bind values from the having clause over to the where clause since
we can't differentiate the two, and assignment was likely in the form
of:
`relation.bind_values += other.bind_values`
This will go away once we remove all places that are assigning
`bind_values`, which is next on the list.
While this fixes a bug that was present in at least 4.2 (more likely
present going back as far as 3.0, becoming more likely in 4.1 and later
as we switched to prepared statements in more cases), I don't think this
can be easily backported. The internal changes to `Relation` are
non-trivial, anything that involves modifying the `bind_values` array
would need to change, and I'm not confident that we have sufficient test
coverage of all of those locations (when `having` was called with a hash
that could generate bind values).

This class cares far too much about the internals of other parts of
Active Record. This is an attempt to break out a meaningful object which
represents the needs of the predicate builder. I'm not fully satisfied
with the name, but the general concept is an object which represents a
table, the associations to/from that table, and the types associated
with it. Many of these exist at the `ActiveRecord::Base` class level,
not as properties of the table itself, hence the need for another
object. Currently it provides these by holding a reference to the class,
but that will likely change in the future. This allows the predicate
builder to remain wholy concerned with building predicates.

Construction of relations can be a hotspot, we don't want to create one
of these in the constructor. This also allows us to do more expensive
things in the predicate builder's constructor, since it's created once
per AR::Base subclass
- Right now, there is no method to update multiple records with
validations and callbacks.
- Changed the behavior of existing `update` method so that when `id`
attribute is not given and the method is called on an `Relation`
object, it will execute update for every record of the `Relation` and
will run validations and callbacks for every record.
- Added test case for validating that the callbacks run when `update` is
called on a `Relation`.
- Changed test_create_columns_not_equal_attributes test from
persistence_test to include author_name column on topics table as it
it used in before_update callback.
- This change introduces performance issues when a large number of
records are to be updated because it runs UPDATE query for every
record of the result. The `update_all` method can be used in that case
if callbacks are not required because it will only run single UPDATE
for all the records.
Arel handles this for us automatically. Updated tests, as BindParam is
no longer a subclass of SqlLiteral. We should remove the second argument
to substitute_at entirely, as it's no longer used
* Also duplicated find_by tests from relations_test.rb to finder_test.rb now
that we have a completely different implementation on the class (in core.rb
with AST caching stuff).
* Also removed a (failing) test that used mocks. Now that we have tests for the
behavior, there's no point having another test that tests the implementation
(that it delegates). Further, what the test was implying is nolonger true with
the current implementation, because Class.find_by is a real method now.
It appears that the only time that `quote` is called with a column,
but without first calling `type_cast` is when where is called with an
array. My previous pull request broke this behavior, without failing
tests. This adds a test for the only case I can think of that exercises
the `if column.type == :integer` branch of `quote` effectively.
When relation scopes include one of `uniq`, `group`, `having` or
`offset`, the generated query ignores them and that causes unintended
records to be deleted. This solves the issue by restricting the deletion
when those scopes are present.

968c581ea34b5236af14805e6a77913b1cb36238 have introduced this bug #14744
on Association Relation when the method `empty?` or `size` was called.
Example:
# Given an author that does have 3 posts, but none of them with the
# title 'Some Title'
Author.last.posts.where(title: 'Some Title').size
# => 3
It was occurring, because the Association Relation had implemented these
methods based on `@association`, this way giving wrong results.
To fix it, was necessary to remove the methods `empty?` and `size` from
Association Relation. It just have to use these methods from Relation.
Example:
# Given an author that does have 3 posts, but none of them with the
# title 'Some Title'
Author.last.posts.where(title: 'Some Title').size
# => 0
# Now it will return the correct value.
Fixes#14744.
