Fixes #16128
This bug was introduced in https://github.com/rails/rails/commit/c35e438620f2d56562251571377995359546393d
so it's present from 4.1.2-rc1 and after.
https://github.com/rails/rails/commit/c35e438620f2d56562251571377995359546393d
merges any relation scopes passed as proc objects to the relation,

Post.where(id: [[]]).to_a
Used to fail with a SQL syntax error (until 4.1):
SELECT ... WHERE id in ();
It now properly generate:
SELECT ... WHERE 1=0;
|
|
|
|
|
|
| |
Example:
Author.where(posts: { author_id: Author.where(country_id: 1) }).joins(:posts)
|

It seems that #where! is not designed to be used as a chained where.
See initial implementation at 8c2c60511beaad05a218e73c4918ab89fb1804f0.
So, no need to check twice.
We should not test #where!

Make filter_binds filter out symbols that are equal to strings

ActiveRecord::Relation::Merger's filter_binds method does not filter out bind
variables when one of the attribute nodes has a string name, but the other has
a symbol name, even when those names are actually equal.
This can result in there being more bind variables than placeholders in the
generated SQL. This is particularly an issue for PostgreSQL, where this is
treated as an error.
This patch changes the filter_binds method to make it convert both attribute
names to strings before comparing.

This is a regression 4.0 -> 4.1 fix.
In 4.1.0 Relation#join is delegated to Arel#SelectManager.
In 4.0 series it is delegated to Array#join
This patch puts back the behaviour of 4.0

The reverse_order method was using a flag to control if the order should
be reversed or not. Instead of using this variable just build the reverse order
inside its proper method.
This implementation was leading to an unexpected behavior when using
reverse_order and then applying reorder(nil).
Example:
Before
Post.order(:name).reverse_order.reorder(nil)
# => SELECT "posts".* FROM "posts" ORDER BY "posts"."id" DESC
After
Post.order(:name).reverse_order.reorder(nil)
# => SELECT "posts".* FROM "posts"

Using the name of an association in `where` previously worked only
if the value was a single `ActiveRecrd::Base` object. e.g.
Post.where(author: Author.first)
Any other values, including `nil`, would cause invalid SQL to be
generated. This change supports arguments in the `where` query
conditions where the key is a `belongs_to` association name and the
value is `nil`, an `Array` of `ActiveRecord::Base` objects, or an
`ActiveRecord::Relation` object.
# Given the Post model
class Post < ActiveRecord::Base
belongs_to :author
end
# nil value finds records where the association is not set
Post.where(author: nil)
# SELECT "posts".* FROM "posts" WHERE "posts"."author_id" IS NULL
# Array values find records where the association foreign key
# matches the ids of the passed ActiveRecord models, resulting
# in the same query as Post.where(author_id: [1,2])
authors_array = [Author.find(1), Author.find(2)]
Post.where(author: authors_array)
# ActiveRecord::Relation values find records using the same
# query as Post.where(author_id: Author.where(last_name: "Emde"))
Post.where(author: Author.where(last_name: "Emde"))
Polymorphic `belongs_to` associations will continue to be handled
appropriately, with the polymorphic `association_type` field added
to the query to match the base class of the value. This feature
previously only worked when the value was a single `ActveRecord::Base`.
class Post < ActiveRecord::Base
belongs_to :author, polymorphic: true
end
Post.where(author: Author.where(last_name: "Emde"))
# Generates a query similar to:
Post.where(author_id: Author.where(last_name: "Emde"), author_type: "Author")

I'm pretty confused about the addition of this method. The documentation
says that it was intended to allow the removal of values from the
default scope (in contrast to #except). However it behaves exactly the
same as except: https://gist.github.com/jonleighton/7537008 (other than
having a slightly enhanced syntax).
The removal of the default scope is allowed by
94924dc32baf78f13e289172534c2e71c9c8cade, which was not a change we
could make until 4.1 due to the need to deprecate things. However after
that change #unscope still gives us nothing that #except doesn't already
give us.
However there *is* a desire to be able to unscope stuff in a way that
persists across merges, which would allow associations to be defined
which unscope stuff from the default scope of the associated model. E.g.
has_many :comments, -> { unscope where: :trashed }
So that's what this change implements. I've also corrected the
documentation. I removed the guide references to #except as I think
unscope really supercedes #except now.
While we're here, there's also a potential desire to be able to write
this:
has_many :comments, -> { unscoped }
However, it doesn't make sense and would not be straightforward to
implement. While with #unscope we're specifying exactly what we want to
be removed from the relation, with "unscoped" we're just saying that we
want it to not have some things which were added earlier on by the
default scope. However in the case of an association, we surely don't
want *all* conditions to be removed, otherwise the above would just
become "SELECT * FROM comments" with no foreign key constraint.
To make the above work, we'd have to somehow tag the relation values
which get added when evaluating the default scope in order to
differentiate them from other relation values. Which is way too much
complexity and therefore not worth it when most use cases can be
satisfied with unscope.
Closes #10643, #11061.

Every method from MRI's core classes is written in C. This means
Method#arity always returns -1 for methods with a variable number of
arguments. This is not the case with Rubinius, where, for example
Array#slice! is implemented in Ruby and has arity -2, since is
defined as def slice!(start, length = undefined)

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.

This adds the ability for rails apps or gems to have granular control
over how a domain object is converted to sql. One simple use case would
be to add support for Regexp. Another simple case would be something
like the following:
class DateRange < Struct.new(:start, :end)
def include?(date)
(start..end).cover?(date)
end
end
class DateRangePredicate
def call(attribute, range)
attribute.in(range.start..range.end)
end
end
ActiveRecord::PredicateBuilder.register_handler(DateRange,
DateRangePredicate.new)
More complex cases might include taking a currency object and converting
it from EUR to USD before performing the query.
By moving the existing handlers to this format, we were also able to
nicely refactor a rather nasty method in PredicateBuilder.

When using symbol keys, ActiveRecord will now translate aliased attribute names to the actual column name used in the database:
With the model
class Topic
alias_attribute :heading, :title
end
The call
Topic.where(heading: 'The First Topic')
should yield the same result as
Topic.where(title: 'The First Topic')
This also applies to ActiveRecord::Relation::Calculations calls such as `Model.sum(:aliased)` and `Model.pluck(:aliased)`.
This will not work with SQL fragment strings like `Model.sum('DISTINCT aliased')`.
