We already have a test case for `serialize` with a custom coder in
`PostgresqlHstoreTest`.

Improves the performance from O(n) to O(1).
Previously it would require 50 queries to
insert 50 fixtures. Now it takes only one query.
Disabled on sqlite which doesn't support multiple inserts.

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.

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.
Fixes #26326.

The default value of `"pg_arrays"."tags"` is being changed to `[]` in
one test, but the column information on the model isn't reset after it's
changed back. As such, we think the default value is `[]` when in the
database it's actually `nil`. That means any test which was assigning
`[]` to a new record would have that key skipped with partial writes, as
it hasn't changed from the default. However since the *actual* default
value is `nil`, we get back values that the test doesn't expect, and it
fails.

This makes it easier for third party adapters to run our tests,

Remaining are `limit`, `precision`, `scale`, and `type` (the symbol
version). These will remain on the column, since they mirror the options
to the `column` method in the schema definition DSL

`.` is regexp meta character. It should be escape for `assert_match`
correctly.

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.

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 behavior has changed since 4.1 and non-array values are no
longer type casted to a blank array. This way the user can define
custom validations on that property.

|

This was only used for uniqueness validations. The first usage was in
conjunction with `limit`. Types which cast to string, but are not
considered text cannot have a limit. The second case was only with an
explicit `:case_sensitive => true` option given by the user.

We have several test cases on "tricky" types that are essentially
testing that `update_all` goes through the same type casting behavior as
a normal assignment + save. We recently had another case to add this
test for another type in https://github.com/rails/rails/pull/12742.
Rather than testing this separately for every type which is "tricky"
when round tripping, let's instead have a fairly exhaustive test that
ensures we're getting the correct values at every step for `update_all`.
Given the structure of the code now, we can be confident that if the
type is correct, and `update_all` is type casting correctly, we're going
to get the right behavior for all types.

Don't type cast the default on the column
|
| |
| |
| |
| |
| |
| |
| | |
If we want to have type decorators mess with the attribute, but not the
column, we need to stop type casting on the column. Where possible, we
changed the tests to test the value of `column_defaults`, which is
public API. `Column#default` is not.

Also takes a step towards supporting types which use a character other
than ',' for the delimiter (`box` is the only built in type for which
this is the case)
|
|
|
|
|
|
| |
We guarantee that `model.value` does not change after
`model.save && model.reload`. This requires type casting user input for
non-string types.
|
|
|
|
|
|
|
|
| |
In some cases there is a difference between the two, we should always
be doing one or the other. For convenience, `type_cast` is still a
private method on type, so new types that do not need different behavior
don't need to implement two methods, but it has been moved to private so
it cannot be used accidentally.

Revert "test pg, remove unused column assignments. Follow up to 254cdf47"
Related to #15492

This reverts commit 4bcf9029452e0c760af04faab6b549710401e8cf.
There are public methods that assume `Column#default` is type casted.
The return value of `Column#default` is publicly relevant and should not change.
