Since #26074, introduced force equality checking to build a predicate
consistently for both `find` and `create` (fixes #27313).
But the assumption that only array/range attribute have subtype was
wrong. We need to make force equality checking more strictly not to
allow serialized attribute.
Fixes #32761.

BC dates are supported by both date and datetime types.
https://www.postgresql.org/docs/current/static/datatype-datetime.html
Since #1097, new datetime allows year zero as 1 BC, but new date does
not. It should be allowed even in new date consistently.

The values infinity and -infinity are supported by both date and
timestamp types.
https://www.postgresql.org/docs/current/static/datatype-datetime.html#DATATYPE-DATETIME-SPECIAL-TABLE
And also, it can not be known whether a value is infinity correctly
unless cast a value.
I've added `QueryAttribute#infinity?` to handle that case.
Closes #27585.

An empty string is an invalid value in Ruby's range class.
So need to handle `Float::INFINITY` as it is and cast it in
`encode_range`.

`BigDecimal.new` has been deprecated in BigDecimal 1.3.3
which will be a default for Ruby 2.5.
Refer https://github.com/ruby/bigdecimal/commit/533737338db915b00dc7168c3602e4b462b23503
```
$ cd rails/activerecord/
$ git grep -l BigDecimal.new | grep \.rb | xargs sed -i -e "s/BigDecimal.new/BigDecimal/g"
```
- Changes made only to Active Record. Will apply the same change to
other module once this commit is merged.
- The following deprecation has not been addressed because it has been
reported at `ActiveRecord::Result.new`. `ActiveRecord::Result.ancestors`
did not show `BigDecimal`.
* Not addressed
```ruby

PostgreSQL 9.1+ introduced range types, and Rails added support for
using this datatype in ActiveRecord. However, the serialization of
`PostgreSQL::OID::Range` was incomplete, because it did not properly
quote the bounds that make up the range. A clear example of this is a
`tsrange`.
Normally, ActiveRecord quotes Date/Time objects to include the
milliseconds. However, the way `PostgreSQL::OID::Range` serialized its
bounds, the milliseconds were dropped. This meant that the value was
incomplete and not equal to the submitted value.
An example of normal timestamps vs. a `tsrange`. Note how the bounds
for the range do not include their milliseconds (they were present in
the ruby Range):
UPDATE "iterations" SET "updated_at" = $1, "range" = $2 WHERE
"iterations"."id" = $3
[["updated_at", "2017-09-23 17:07:01.304864"],
["range", "[2017-09-23 00:00:00 UTC,2017-09-23 23:59:59 UTC]"],
["id", 1234]]
`PostgreSQL::OID::Range` serialized the range by interpolating a
string for the range, which works for most cases, but does not work
for timestamps:
def serialize(value)
if value.is_a?(::Range)
from = type_cast_single_for_database(value.begin)
to = type_cast_single_for_database(value.end)
"[#{from},#{to}#{value.exclude_end? ? ')' : ']'}"
else
super
end
end
(byebug) from = type_cast_single_for_database(value.begin)
2010-01-01 13:30:00 UTC
(byebug) to = type_cast_single_for_database(value.end)
2011-02-02 19:30:00 UTC
(byebug) "[#{from},#{to}#{value.exclude_end? ? ')' : ']'}"
"[2010-01-01 13:30:00 UTC,2011-02-02 19:30:00 UTC)"
@sgrif (the original implementer for Postgres Range support) provided
some feedback about where the quoting should occur:
Yeah, quoting at all is definitely wrong here. I'm not sure what I
was thinking in 02579b5, but what this is doing is definitely in the
wrong place. It should probably just be returning a range of
subtype.serialize(value.begin) and subtype.serialize(value.end), and
letting the adapter handle the rest.
`Postgres::OID::Range` now returns a `Range` object, and
`ActiveRecord::ConnectionAdapters::PostgreSQL::Quoting` can now encode
and quote a `Range`:
def encode_range(range)
"[#{type_cast(range.first)},#{type_cast(range.last)}#{range.exclude_end? ? ')' : ']'}"
end
...
encode_range(range)
#=> "['2010-01-01 13:30:00.670277','2011-02-02 19:30:00.745125')"
This commit includes tests to make sure the milliseconds are
preserved in `tsrange` and `tstzrange` columns

Make `type_map` to private because it is only used in the connection adapter
|
| |
| |
| |
| |
| |
| |
| | |
`type_map` is an internal API and it is only used in the connection
adapter. And also, some type map initializer methods requires passed
`type_map`, but those instances already has `type_map` in itself.
So we don't need explicit passing `type_map` to the initializers.

The uuid validation regex was allowing uuids to have a single leading
curly brace or single trailing curly brace. Saving with such a uuid
would cause Postgres to generate an exception even though the record
seemed valid. With this change, the regex requires both a leading *and*
a trailing curly brace or neither to be valid.

Per the regression commit below, the commit changes the behavior of
`#changed?`to consult the `#changed_in_place?` method on `Type::Value` classes.
Per this change, `PostgreSQL::OID::Hstore` needs to override this method
in order to compare the deserialized forms of the two arguments. In
Ruby, two hashes are considered equal even if their key order is
different. This commit helps to bring that behavior to `Hstore` values.

In f1a0fa9 we moved backend specific timestamp behavior out of the type
and into the adapter. This was in line with our general attempt to
reduce the number of adapter specific type subclasses. However, on PG,
the array type performs all serialization, including database encoding
in its serialize method.
This means that we have converted the value into a string before
reaching the database, so no adapter specific logic can be applied (and
this also means that timestamp arrays were using the default `.to_s`
method on the given object, which likely meant timestamps were being
ignored in certain cases as well)
Ultimately I want to do a more in depth refactoring which separates
database serializer objects from the active model type objects, to give
us a less awkward API for introducing the attributes API onto Active
Model.
However, in the short term, we follow the solution we've applied
elsewhere for this. Move behavior off of the type and into the adapter,
and use a data object to allow the type to communicate information up
the stack.
Fixes #27514.

`PG::TextEncoder::Array#encode` returns the encoded value with `ASCII-8BIT`.
But in some cases, trying to convert `ASCII-8BIT` to `UTF-8` cause an error.
```ruby
"{\xE3\x83\x95\xE3\x82\xA1\xE3\x82\xA4\xE3\x83\xAB}".encode!(Encoding::UTF_8)
# => Encoding::UndefinedConversionError: "\xE3" from ASCII-8BIT to UTF-8
```
Should use `force_encoding` to avoid this error.

As reported via #26904, there is a regression in how values for
Postgres' HStore column type are being processed, beginning in Rails 5.
Currently, the way that Active Record checks whether or not values need
to be serialized and put into the correct storage format is whether or
not it is a `Hash` object. Since `ActionController::Parameters` no
longer inherits from `Hash` in Rails 5, this conditional now returns
false. To remedy this, we are now checking to see whether the `value`
parameters being passed in responds to a certain method, and then
calling the `serialize` method, except this time with a real Hash
object. Keeping things DRY!
Fixes #26904.

There are some minor changes to the point type as I had forgotten that
this will affect the behavior of `t.point` in migrations and the schema
dumper so we need to handle those as well.
I'll say this again so I can convince myself to come up with a better
structure... TYPES SHOULD NOT CARE ABOUT SCHEMA DUMPING AND WE NEED TO
BETTER SEPARATE THESE.

I still think that this is something that should be handled in the pg
gem, but it's not going to end up happening there so we'll do it here
instead. Once we bump to pg 0.19 we can pass the encoding to the
`encode` method instead.
This issue occurs because C has no concept of encoding (or strings,
really). The bytes that we pass here when sending the value to the
database will always be interpreted as whatever encoding the connection
is currently configured to use. That means that roundtripping to the
database will lose no information
However, after assigning we round trip through our type system without
hitting the database. The only way that we can do the "correct" thin
here would be to actually give a reference to the connection to the
array type and have it check the current value of the connection's
encoding -- which I'm strongly opposed to. We could also pass in the
encoding when it's constructed, but since that can change independently
of the type I'm not a huge fan of that either.
This feels like a reasonable middle ground, where if we have an array of
strings we simply use the encoding of the string we're given.

This is an alternate implementation to #22875, that generalizes a lot of
the logic that type decorators are going to need, in order to have them
work with arrays, ranges, etc. The types have the ability to map over a
value, with the default implementation being to just yield that given
value. Array and Range give more appropriate definitions.
This does not automatically make ranges time zone aware, as they need to
be added to the `time_zone_aware` types config, but we could certainly
make that change if we feel it is appropriate. I do think this would be
a breaking change however, and should at least have a deprecation cycle.
Closes #22875.

Timestamp column can have less precision than ruby timestamp
In result in how big a fraction of a second can be stored in the
database.
m = Model.create!
m.created_at.usec == m.reload.created_at.usec
# => false
# due to different seconds precision in Time.now and database column
If the precision is low enough, (mysql default is 0, so it is always low
enough by default) the value changes when model is reloaded from the
database. This patch fixes that issue ensuring that any timestamp
assigned as an attribute is converted to column precision under the
attribute.

Several changes were made in #21110 which I am strongly opposed to.
(this is what I get for going on vacation. :trollface:) No type should
be introduced into the generic `ActiveRecord::Type` namespace, and
*certainly* should not be registered into the registry unconstrained
unless it is supported by *all* adapters (which basically means that it
was specified in the ANSI SQL standard).
I do not think `# :nodoc:` ing the type is sufficient, as it still makes
the code of Rails itself very unclear as to what the role of that class
is. While I would argue that this shouldn't even be a super class, and
that MySql and PG's JSON types are only superficially duplicated (they
might look the same but will change for different reasons in the
future).
However, I don't feel strongly enough about it as a point of contention
(and the biggest cost of harming the blameability has already occured),
so I simply moved the superclass into a namespace where its role is
absolutely clear.
After this change, `attribute :foo, :json` will once again work with
MySQL and PG, but not with Sqlite3 or any third party adapters.
Unresolved questions
--------------------
The types that and adapter publishes (at least those are unique to that
adapter, and not adding additional behavior like `MysqlString` should
probably be part of the adapter's public API. Should we standardize the
namespace for these, and document them?

As of MySQL 5.7.8, MySQL supports a native JSON data type.
Example:
create_table :json_data_type do |t|
t.json :settings
end

|
|
|
|
|
|
|
|
| |
If the subtype provides custom schema dumping behavior, we need to defer
to it. We purposely choose not to handle any values other than an array
(which technically should only ever be `nil`, but I'd rather code
defensively here).
Fixes #20515.
