Call assume_migrated_upto_version on connection to prevent it from first
being picked up in method_missing. In the base class, Migration,
method_missing expects the argument to be a table name, and calls
proper_table_name on the arguments before sending to connection. If
table_name_prefix or table_name_suffix is used, the schema version changes
to prefix_version_suffix, breaking `rake test:prepare`.
Fixes #10411.

Fix that #exists? can produce invalid SQL: "SELECT DISTINCT DISTINCT"

The combination of a :uniq => true association and the #distinct call
in #construct_limited_ids_condition combine to create invalid SQL, because
we're explicitly selecting DISTINCT, and also sending #distinct on to AREL,
via the relation#distinct_value.
Rather than build a select distinct clause in #construct_limited_ids_condition,
I set #distinct! and pass just the columns into the select statement.
This requires introducing a #columns_for_distinct method to return the
select columns but not the statement itself.

Suppose Man has_many interests, and inverse_of is used.
Man.first.interests.first.man will correctly execute two queries,
avoiding the need for a third query when Interest#man is called. This is
because CollectionAssociation#first calls set_inverse_instance.
However Man.first.interests.where("1=1").first.man will execute three
queries, even though this is obviously a subset of the records in the
association.
This is because calling where("1=1") spawns a new Relation object from
the CollectionProxy object, and the Relation has no knowledge of the
association, so it cannot set the inverse instance.
This commit solves the problem by making relations spawned from
CollectionProxies return a new Relation subclass called
AssociationRelation, which does know about associations. Records loaded
from this class will get the inverse instance set properly.
Fixes #5717.

patricksrobertson/bigserial_id_not_identifying_pk"

In #10410 it was noted that you can no longer create PK's with the
type of bigserial in PostgreSQL in 4.0.0.rc1. This is mostly
because the newer adapter is checking for column type with the
id column instead of just letting it pass through like it did
before.
Side effects:
You may just create a PK column of a type that you really don't
want to be your PK. As far as I can tell this was allowed in 3.2.X
and perhaps an exception should be raised if you try and do
something extremely dumb.

fixes #10419
Following code should raise IrreversibleMigration. But the code was
failing since options is an array and not a hash.
def change
change_table :users do |t|
t.remove_index [:name, :email]
end
end
Fix was to check if the options is a Hash before operating on it.

For one-to-one nested associations, if you build the new (in-memory)
child object yourself before assignment, then the NestedAttributes
module will not overwrite it, e.g.:
class Member < ActiveRecord::Base
has_one :avatar
accepts_nested_attributes_for :avatar
def avatar
super || build_avatar(width: 200)
end
end
member = Member.new
member.avatar_attributes = {icon: 'sad'}
member.avatar.width # => 200

autosave_association issue that occurs when table has unique index (resubmission)

fixes bug introduced by #3329
These are the conditions necessary to reproduce the bug:
- For an association, autosave => true.
- An association record is being destroyed
- A new association record is being created.
- There is a unique index one of the association's fields.
- The record being created has the same value as the record being
destroyed on the indexed field.
Before, the deletion of records was postponed until after all
insertions/saves. Therefore the new record with the identical value in
the indexed field caused a non-unique value error to be thrown at the database
level.
With this fix, the deletions happen first, before the insertions/saves.
Therefore the record with the duplicate value is gone from the database
before the new record is created, thereby avoiding the non-uniuqe value
error.

test_mysql_integer_not_null_defaults in test/cases/defaults_test.rb was
failing. This test relies on the connection being in strict mode. By
default a new connection is not in strict mode, but Active Record
automatically places it in strict mode.
ActiveSchemaTest overwrites the connection's #execute method in order to
prevent SQL statements from actually being executed. One of the
operations which is performed in ActiveSchema test is a #recreate_database.
Since 2088bf27981137a2c6c8b2f718f33b417b4045af, recreate_database on
mysql or mysql2 will trigger a reconnect.
Due to the implementation of the hacking of #execute in
ActiveSchemaTest, this reconnect would take place, but the connection
would *not* be placed in strict mode because #execute had been
overridden to prevent SQL queries hitting the database.
Therefore, after ActiveSchemaTest, the connection would no longer be in
strict mode, causing test_mysql_integer_not_null_defaults to fail.
I don't think that the way that ActiveSchemaTest is implemented is
particularly nice or clean, but I have taken steps to make its hacks
more isolated - it now create a separate connection object which is
thrown away after the test, and the hacks are applied on the singleton
class of this object.

According to the doc of `AR::Base#to_param`(
https://github.com/rails/rails/blob/04cda1848cb847c2bdad0bfc12160dc8d554
7775/activerecord/lib/active_record/integration.rb#L18 ), it returns
`nil` if the record is not persisted.

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')`.

activerecord/lib/active_record/associations.rb states:
# [association=(associate)]
# Assigns the associate object, extracts the primary key, sets it as the foreign key,
# and saves the associate object.
Since commit 42dd5d9f2976677a4bf22347f2dde1a8135dfbb4 to fix #7191, this
is no longer the case if the associate has changed, but is the same
object. For example:
# Pirate has_one :ship
pirate = Pirate.create!(catchphrase: "A Pirate")
ship = pirate.build_ship(name: 'old name')
ship.save!
ship.name = 'new name'
pirate.ship = ship
That last line should trigger a save. Although we are not changing the
association, the associate (ship) has changed.
