When replacing a has_many association with the same one, there is no
need to do a round-trip to the db to create/and drop a new transaction.
[fixes#14220]
This is a partial revert of 22b3481ba2aa55fad1f9a5db94072312b345fb55.
The current implementation of `references_eager_loaded_tables?` needs to know
every table involved in the query. With the current API this is not possible
without SQL parsing.
While a2dab46cae35a06fd5c5500037177492a047c252 deprecated SQL parsing for `includes`.
It did not issue deprecation warnings when String joins are involved. This resulted
in a breaking change after the deprecated behavior was removed (22b3481ba2aa55fad1f9a5db94072312b345fb55).
We will need to rethink the usage of `includes`, `preload` and `eager_load` but for now,
this brings back the old *working* behavior.
This fixes a bug where any enum attribute of a model
would be evaluated always as 0 when calling the
database on validations.
This fix converts the value of the enum attribute
to its integer value rather than the string before
building the relation as the bug occured when the
string finally gets converted to integer using
string.to_i which converts it to 0.

This test currently outputs the following warning:
```
unknown OID: current_mood(3567879) (SELECT "postgresql_enums".* FROM "postgresql_enums" ORDER BY "postgresql_enums"."id" ASC LIMIT 1)
unknown OID: current_mood(3567879) (SELECT "postgresql_enums".* FROM "postgresql_enums" WHERE "postgresql_enums"."id" = $1 LIMIT 1)
```
We have an open PR to deal with this issue. It will dynamically
register the OID for enum columns. This test case is merely to exhibit
the current behavior of PostgreSQL enum columns.
`before_add` callbacks are fired before the record is saved on
`has_and_belongs_to_many` assocations *and* on `has_many :through`
associations. Before this change, `before_add` callbacks would be fired
before the record was saved on `has_and_belongs_to_many` associations, but
*not* on `has_many :through` associations.
Fixes#14144
conflicting private method defined on its ancestors.
The problem is that `method_defined_within?(name, klass, superklass)`
only works correclty when `klass` and `superklass` are both `Class`es.
If both `klass` and `superklass` are both `Class`es, they share the
same inheritance chain, so if a method is defined on `klass` but not
`superklass`, this method must be introduced at some point between
`klass` and `superklass`.
This does not work when `superklass` is a `Module`. A `Module`'s
inheritance chain contains just itself. So if a method is defined on
`klass` but not on `superklass`, the method could still be defined
somewhere upstream, e.g. in `Object`.
This fix works by avoiding calling `method_defined_within?` with a
module while still fufilling the requirement (checking that the
method is defined withing `superclass` but not is not a generated
attribute method).
4d8ee288 is likely an attempted partial fix for this problem. This
unrolls that fix and properly check the `superclass` as intended.
Fixes#11569.
The Ruby Range object does not support excluding beginnings.
We currently support excluding beginnings for some subtypes using
manually by incrementing them (now using the `#succ` method).
This is approach is flawed as it's not equal to an excluding beginning.
This commit deprecates the current support for excluding beginnings.
It also raises an `ArgumentError` for subtypes that do not implement the `succ`
method.
This is a temporary solution to get rid of the broken state. We might still
add complete support for excluding beginnings afterwards. (Probably with a
new `PGRange` object, which acts like a `Range` but has excluding beginnings.
This gets AR working with custom defined range types. It also
removes the need for subtype specific branches in `OID::Range`.
This expands the interface of all `OID` types with the `infinity` method.
It's responsible to provide a value for positive and negative infinity.
If using a `DATABASE_URL` and a `database.yml`. The connection information in `DATABASE_URL` should be merged into whatever environment we are in. As released in 4.1.0rc1 if someone has a database.yml but is missing a key like production:
```yml
development:
host: localhost
```
Then the check for blank config will return false so the information from the `DATABASE_URL` will not be used when attempting to connect to the `production` database and the connection will incorrectly fail.
This commit fixes this problem and adds a test for the behavior.
In addition the ability to specify a connection url in a `database.yml` like this:
```
production: postgres://localhost/foo
```
Was introduced in 4.1.0rc1 though should not be used, instead using a url sub key
```
production:
url: postgres://localhost/foo
```
This url sub key was also introduced in 4.1.0rc1 though the `production: postgres://localhost/foo` was not removed. As a result we should not test this behavior.
This reverts commit 3ea840355409dc205a9e0d027fc09f1452636969, reversing
changes made to e4cde5d58cbb09d1843796f96ba86225ff94fe05.
Conflicts:
activerecord/CHANGELOG.md
activerecord/lib/active_record/relation/query_methods.rb
Reason: using `from` without `select` should not change the select list
to SELECT * because it can lead different query results. If it is needed
to change the table to a subquery or a view you can pass a table alias
in the `from` call or use `select('subquery.*')`.
Fixes#14049.
We didn't have enough encoding for the wire protocol to store an array
of hstore types. So, further encode any hstore that is an array member.
Whilst we're here, ensure it's an HashWithIndifferentAccess being
returned, to be consistent with other serialized forms, and add testing
for arrays of hstore.
So now the following migration:
enable_extension "hstore"
create_table :servers do |t|
t.string :name
t.hstore :interfaces, array: true
end
produces a model that can used like this, to store an array of hashes:
server = Server.create(name: "server01", interfaces: [
{ name: "bge0", ipv4: "192.0.2.2", state: "up" },
{ name: "de0", state: "disabled", by: "misha" },
{ name: "fe0", state: "up" },
])

If the test is run in a timezone that is behind UTC it fails because
the time generated is ahead of 0000-01-01 00:00:00. Just increase the
time subtracted so that timezone has no effect.
