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,
even if that database does not support IF EXISTS.

This predicate is only used in `query_attribute`, and is relatively easy
to remove without adding a bunch of is a checks.

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 254cdf4728291277f3fbaa854f34495030e476b4.
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.

That data is internal to Active Record. What we care about is that
new records have the right default value.

There is no reason for the PG adapter to have a default limit of 255 on :string
columns. See this snippet from the PG docs:
Tip: There is no performance difference among these three types, apart
from increased storage space when using the blank-padded type, and a
few extra CPU cycles to check the length when storing into a
length-constrained column. While character(n) has performance
advantages in some other database systems, there is no such advantage
in PostgreSQL; in fact character(n) is usually the slowest of the
three because of its additional storage costs. In most situations text
or character varying should be used instead.

Ensure that SQLCounter.clear_log is called after each test.
This is a step to prevent side effects when running tests. This will allow us to run them in random order.

The code uses these checks in several places to know what to do with a
particular column, for instance AR attribute query methods has a branch
like this:
if column.number?
!value.zero?
end
This should never be true for array columns, since it would be the same
as running [].zero?, which results in a NoMethodError exception.
Fixing this by ensuring that array columns in PostgreSQL never return
true for number?/text? checks.
Since most of the array support was based on the postgres_ext lib, it's
worth noting it does the same thing for numeric array columns too:
https://github.com/dockyard/postgres_ext/blob/v1.0.0/lib/postgres_ext/active_record/connection_adapters/postgres_adapter.rb#L72
This extended the same logic for text columns to ensure consistency.
