If set to `if_exists: true`, it generates a statement like:
DROP TABLE IF EXISTS posts
This syntax is supported in the popular SQL servers, that is (at least)
SQLite, PostgreSQL, MySQL, Oracle and MS SQL Sever.
Closes #16366.

The types that are affected by `time_zone_aware_attributes` (which is on
by default) have been made configurable, in case this is a breaking
change for existing applications.

Slightly refactoring `PostgreSQLColumn`. `array` should be readonly.
`default_function` should be initialized by `super`. `sql_type` has been
removed `[]`. Since we already choose to remove it we should not change.

This showed up when running BinaryTest#test_load_save with the more
restrictive input string handling of pg-0.18.0.pre20141117110243.gem .
Bytea values sent to the server are in binary format, but are
returned back as escaped text. To fulfill the assumption that
type_cast_from_database(type_cast_for_database(binary)) == binary
we unescape only, if the value was really received from the server.

When table has a composite primary key, the `primary_key` method for
sqlite3 and postgresql was only returning the first field of the key.
Ensures that it will return nil instead, as AR dont support composite pks.

Because call the `column` method and set the `options[:primary_key]` is
handled at `super`, here need only treat the `options[:default]`.

I think we should deprecate this behavior and just error if you tell us
to do a case insensitive comparison for types which are not case
sensitive. Partially reverts 35592307

Apparently PG does not validate against RFC 4122. The intent of the original
patch is just to protect against PG errors (which potentially breaks txns, etc)
because of bad user input, so we shouldn't try any harder than PG itself.

The user is able to pass PG string literals in 4.1, and have it
converted to an array. This is also possible in 4.2, but it would remain
in string form until saving and reloading, which breaks our
`attr = save.reload.attr` contract. I think we should deprecate this in
5.0, and only allow array input from user sources. However, this
currently constitutes a breaking change to public API that did not go
through a deprecation cycle.

The type registration was simply looking for the OID, and eagerly
fetching/constructing the sub type when it was registered. However,
numeric types have additional parameters which are extracted from the
actual SQL string of the type during lookup, and can have their behavior
change based on the result.
We simply need to use the block form of registration, and look up the
subtype lazily instead.
Fixes #17935

Not sure how we missed this case when we moved everything else to the
`_quote` method.

This allows us so abstract the migration from the type that is actually
used by Rails. For example, ":string" may be a varchar or something,
but the framework does that translation, and the app shouldn't need to
know.

Also checked to make sure this does not affect foreign key constraints.

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
|
|
|
|
|
|
| |
This caused a pretty major performance regression for 4.2, as this is a
hotspot for query construction. We're still slightly slower than 4.1,
but it's much less significant.

Remove redundant substitute index when constructing bind values

We end up re-ordering them either way when we construct the Arel AST (in order
to deal with rewhere, etc), so we shouldn't bother giving it a number in the
first place beforehand.

Skip setting sequence on a table create if the value is 0 since it will start the first value at 1 anyway.
This fixes the PG error 'setval: value 0 is out of bounds for sequence vms_id_seq...' encountered when migrating a new DB.

The current style for warning messages without newlines uses
concatenation of string literals with manual trailing spaces
where needed.
Heredocs have better readability, and with `squish` we can still
produce a single line.
This is a similar use case to the one that motivated defining
`strip_heredoc`, heredocs are super clean.

While investigating #16951 I found that another library's monkey-patching of
`Enumerable` was causing the test migrations helper to break when trying to
build the `CREATE DATABASE` statement. The prior approach used `#sum` to build
the string from the options hash.
As the code that combines the options to build the database statement is not
user-facing, using `#inject` here instead will remove the only place where the
database creation/migration code is dependent on ActiveSupport's monkey-patching
of `Enumerable`.

TableDefinition#column is not called from `add_column`.
Use TableDefinition#new_column_definition for column option handling.
|
|
|
|
|
|
|
|
|
|

Using heredoc would enforce line wrapping to whatever column width we decided to
use in the code, making it difficult for the users to read on some consoles.
This does make the source code read slightly worse and a bit more error-prone,
but this seems like a fair price to pay since the primary purpose for these
messages are for the users to read and the code will not stick around for too
long.

This is a reacon to https://github.com/rails/rails/commit/d6c1205584b1ba597db4071b168681678b1e9875#commitcomment-7502487
This backwards incompatibility was introduced with d6c12055 to fix #7516.
However both `connection.default_sequence_name` and `model.sequence_name` are public API.
The PostgreSQL adapter should honor the interface and return strings.
