Rather than having to do:
create_table :posts do |t|
t.references :user
end
add_foreign_key :posts, :users
You can instead do:
create_table :posts do |t|
t.references :user, foreign_key: true
end
Similar to the `index` option, you can also pass a hash. This will be
passed as the options to `add_foreign_key`. e.g.:
create_table :posts do |t|
t.references :user, foreign_key: { primary_key: :other_id }
end
is equivalent to
create_table :posts do |t|
t.references :user
end
add_foreign_key :posts, :users, primary_key: :other_id
The changes in #18149 added tests for the app generator, but only fixed
it for the plugin generator (I should have let CI finish though I think
it would have failed as an allowed failure).
If the test is interrupted in a way that the teardown block fails to
run, the tests will fail to run until the table is removed manually
without this option.
PG doesn't register it's types using the `int(4)` format that others do.
As such, if we alias `int8` to the other integer types, the range
information is lost. This is fixed by simply registering it separately.
The other option (which I specifically chose to avoid) is to pass the
information of the original type that was being aliased as an argument.
I'd rather avoid that, since an alias should truly be treated the same.
If we need different behavior for a different type, we should explicitly
register it with that, and not have a conditional based on aliasing.
Fixes#18144

The default value for the argument `message` in
`ActiveModel::Errors#add` has a new behavior
since ca99ab2481d44d67bc392d0ec1125ff1439e9f94.
Before
person.errors.add(:name, nil)
# => ["is invalid"]
After
person.errors.add(:name, nil)
# => [nil]
The `Sheep` fixture was added in eb23754e when moving template tests
from actionpack to actionview, but it's not actually used in ActionView tests.
The `Sheep` fixture is only used to test `uncountable` in ActiveModel tests,
and is already defined in activemodel/test/models/sheep.rb
1. Specify that you need to create the test databases, and that no special
Rails command needs to be run to do that.
2. Although the underscore style of `rake test_mysql` works, make the
documentation of running the tests in RUNNING_UNIT_TESTS.rdoc
consistent with the "Contributing..." guide.
3. Promote "Testing Active Record" to not be a subsection of
"Running a Single Test," since it doesn't make sense as a subsection
of that.
ActiveJob::Arguments uses Hash#with_indifferent_access.
But, activejob gem does not require Hash extension library.
When we use activejob as standalone,
we need extra require statement. This is unhandy.
This commit fixes it.
