Between 4.2 and 5.0 the behavior of how multiparameter attributes
interact with `_before_type_cast` changed. In 4.2 it returns the
post-type-cast value. After 5.0, it returns the hash that gets sent to
the type. This behavior is correct, but will cause an issue if you then
tried to render that value in an input like `text_field` or
`hidden_field`.
In this case, we want those fields to use the post-type-cast form,
instead of the `_before_type_cast` (the main reason it uses
`_before_type_cast` at all is to avoid losing data when casting a
non-numeric string to integer).
I've opted to modify `came_from_user?` rather than introduce a new
method for this as I want to avoid complicating that contract further,
and technically the multiparameter hash didn't come from assignment, it
was constructed internally by AR.
Close #27888.

Remove useless `arel_engine`

`arel_engine` is only used in `raise_record_not_found_exception!` to use
`engine.connection` (and `connection.visitor`) in `arel.where_sql`.
https://github.com/rails/arel/blob/v8.0.0/lib/arel/select_manager.rb#L183
But `klass.connection` will work as expected even if not using
`arel_engine` (described by `test_connection`). So `arel_engine` is no
longer needed.

This change was introduced by #18109. The intent of that change was to
specifically apply `unscoped`, not to allow all changes to
`current_scope` to affect the join. The idea of allowing `current_scope`
to affect joins is interesting and potentially more consistent, but has
sever problems associated with it. The fact that we're specifically
stripping out joins indicates one such problem (and potentially leads to
invalid queries).
Ultimately it's difficult to reason about what `Posts.joins(:users)`
actually means if it's affected by `User.current_scope`, and it's
difficult to specifically control what does or doesn't get added. If we
were starting from scratch, I don't think I'd have `joins` be affected
by `default_scope` either, but that's too big of a breaking change to
make at this point.
With this change, we no longer apply `current_scope` when bringing in
joins, with the singular exception of the motivating use case which
introduced this bug, which is providing a way to *opt-out* of having the
default scope apply to joins.
Fixes #29338.

We have some indentation cops. But now there is a little inconsistent
params indentations. Enable `Layout/FirstParameterIndentation` cop to
prevent newly inconsistent indentation added and auto-correct to
existing violations.

Fix `create_with` with multiparameter attributes

I investigated where `scope_for_create` is reused in tests with the
following code:
```diff
--- a/activerecord/lib/active_record/relation.rb
+++ b/activerecord/lib/active_record/relation.rb
@@ -590,6 +590,10 @@ def where_values_hash(relation_table_name = table_name)
end
def scope_for_create
+ if defined?(@scope_for_create) && @scope_for_create
+ puts caller
+ puts "defined"
+ end
@scope_for_create ||= where_values_hash.merge!(create_with_value.stringify_keys)
end
```
It was hit only `test_scope_for_create_is_cached`. This means that
`scope_for_create` will not be reused in normal use cases. So we can
remove caching `scope_for_create` to respect changing `where_clause` and
`create_with_value`.

This is related with #27680.
Since `where_values_hash` keys constructed by `where` are string, so we
need `stringify_keys` to `create_with_value` before merging it.
|
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | | |
Because Arel is a private API and to describe `where_values_hash` keys
constructed by `where` are string.

Change sqlite3 boolean serialization to use 1 and 0
|

Abstract boolean serialization has been using 't' and 'f', with MySQL
overriding that to use 1 and 0.
This has the advantage that SQLite natively recognizes 1 and 0 as true
and false, but does not natively recognize 't' and 'f'.
This change in serialization requires a migration of stored boolean data
for SQLite databases, so it's implemented behind a configuration flag
whose default false value is deprecated. The flag itself can be
deprecated in a future version of Rails. While loaded models will give
the correct result for boolean columns without migrating old data,
where() clauses will interact incorrectly with old data.
While working in this area, also change the abstract adapter to use
`"TRUE"` and `"FALSE"` as quoted values and `true` and `false` for
unquoted. These are supported by PostreSQL, and MySQL remains
overriden.

Don't allow uuids with orphan curly braces
|

| | | |
| | | |
| | | |
| | | | |
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.

Skip query cache for in_batches and friends

The `find_each`, `find_in_batches` and `in_batches` APIs usually operate
on large numbers of records, where it's preferable not to load them all
into memory at once.
If the query cache is enabled, it will hold onto the query results until
the end of the execution context (request/job), which means the memory
used is still proportional to the total number of records. These queries
are typically not repeated, so the query cache isn't desirable here.

The AbstractAdapter will translate all StandardErrors generated during the course of a query into ActiveRecord::StatementInvalids. Unfortunately, it'll also mangle non-database-related errors generated in ActiveSupport::Notification callbacks after the query has successfully completed. This should prevent it from translating errors from ActiveSupport::Notifications.

Let's say you have a nested transaction and both records are saved.
Before the outer transaction closes, a rollback is performed. Previously
the record in the outer transaction would get marked as not persisted
but the inner transaction would get persisted.
```ruby
Post.transaction do
post_one.save # will get rolled back
Post.transaction(requires_new: true) do
post_two.save # incorrectly remains marked as persisted
end
raise ActiveRecord::Rollback
end
```
To fix this the PR changes transaction handling to have the child
transaction ask the parent how the records should be marked. When
there are child transactions, it will always be a SavpointTransaction
because the stack isn't empty. From there we pass the parent_transaction
to the child SavepointTransaction where we add the children to the parent
so the parent can mark the inner transaction as rolledback and thus mark
the record as not persisted.
`update_attributes_from_transaction_state` uses the `completed?` check to
correctly mark all the transactions as rolledback and the inner record as
not persisted.
```ruby
Post.transaction do
post_one.save # will get rolled back
Post.transaction(requires_new: true) do
post_two.save # with new behavior, correctly marked as not persisted
on rollback
end
raise ActiveRecord::Rollback
end
```

`set_state` was directly setting the transaction state instance
variable. It's better to set the state via specific methods (`rollback!`
and `commit!` respectively.
While undocumented and untested, it's possible someone is using
`set_state` in their app or gem so I've added a deprecation notice to
it.
No where in the app do we use `nullify!` but I wanted to keep existing
behavior while replacing the method with a better pattern.
