Make possible to have an association called

.Fixes #11645.

to_sql
on an association now matches the query that is actually executed, where it could previously have incorrectly accrued additional conditions (e.g. as a result of a previous query). CollectionProxy now always defers to the association scope'sarel
method so the (incorrect) inherited one should be entirely concealed.Fixes #14003.

Block a few default Class methods as scope name.
For instance, this will raise:
scope :public, -> { where(status: 1) }

Switch
sqlite3:///
URLs (which were temporarily deprecated in 4.1) from relative to absolute.If you still want the previous interpretation, you should replace
sqlite3:///my/path
withsqlite3:my/path

Fixes #14393.

-
Introduce
validate
as an alias forvalid?
.This is more intuitive when you want to run validations but don't care about the return value.

Create indexes inline in CREATE TABLE for MySQL.
This is important, because adding an index on a temporary table after it has been created would commit the transaction.
It also allows creating and dropping indexed tables with fewer queries and fewer permissions required.
Example:
create_table :temp, temporary: true, as: "SELECT id, name, zip FROM a_really_complicated_query" do |t| t.index :zip end # => CREATE TEMPORARY TABLE temp (INDEX (zip)) AS SELECT id, name, zip FROM a_really_complicated_query

Use singular table name in generated migrations when

touch
accepts many attributes to be touched at once.Example:
# touches :signed_at, :sealed_at, and :updated_at/on attributes. Photo.last.touch(:signed_at, :sealed_at)

-
rake db:structure:dump
only dumps schema information if the schema migration table exists.Fixes #14217.

Reap connections that were checked out by now-dead threads, instead of waiting until they disconnect by themselves. Before this change, a suitably constructed series of short-lived threads could starve the connection pool, without ever having more than a couple alive at the same time.

pk_and_sequence_for
now ensures that only the pg_depend entries pointing to pg_class, and thus only sequence objects, are considered.Josh Williams

Fixed error with validation with enum fields for records where the value for any enum attribute is always evaluated as 0 during uniqueness validation.
Fixes #14172.

before_add
callbacks are fired before the record is saved onhas_and_belongs_to_many
assocations and onhas_many :through
associations. Before this change,before_add
callbacks would be fired before the record was saved onhas_and_belongs_to_many
associations, but not onhas_many :through
associations.Fixes #14144.

Fixed STI classes not defining an attribute method if there is a conflicting private method defined on its ancestors.
Fixes #11569.

Coerce strings when reading attributes. Fixes #10485.
Example:
book = Book.new(title: 12345) book.save! book.title # => "12345"

Deprecate half-baked support for PostgreSQL range values with excluding beginnings. We currently map PostgreSQL ranges to Ruby ranges. This conversion is not fully possible because the Ruby range does not support excluded beginnings.
The current solution of incrementing the beginning is not correct and is now deprecated. For subtypes where we don't know how to increment (e.g.
#succ
is not defined) it will raise an ArgumentException for ranges with excluding beginnings.Yves Senn
-
Support for user created range types in PostgreSQL.
