Move `UnknownAttributeError` to a more sane namespace
|
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
The name `ActiveModel::AttributeAssignment::UnknownAttributeError` is
too implementation specific so let's move the constant directly under
the ActiveModel namespace.
Also since this constant used to be under the ActiveRecord namespace, to
make the upgrade path easier, let's avoid raising the former constant
when we deal with this error on the Active Record side.

We only set the state on the record if that condition is `false` in the
first place, so we dont need to call that again. Also that call is
expensive, follow benchmark with before and after this change:

directly
calling `sync_with_transaction_state` is not fast, so if we call it
once, we can improve the performance of the `persisted?` method. This
is important because every call to `url_for(model)` will call
`persisted?`, so we want that to be fast.
Here is the benchmark:
```ruby
require 'active_record'
ActiveRecord::Base.establish_connection adapter: "sqlite3", database: ":memory:"
ActiveRecord::Base.connection.instance_eval do
create_table(:articles)
end
class Article < ActiveRecord::Base; end
article = Article.new.tap(&:save!)
Benchmark.ips do |x|
x.report("persisted?") do
article.persisted?
end
end
```
Before this patch:
```
$ bundle exec ruby -rbenchmark/ips persisted.rb
Calculating -------------------------------------
persisted? 3.333k i/100ms
-------------------------------------------------
persisted? 51.037k (± 8.2%) i/s - 253.308k
```
After:
```
$ bundle exec ruby -rbenchmark/ips persisted.rb
Calculating -------------------------------------
persisted? 7.172k i/100ms
-------------------------------------------------
persisted? 120.730k (± 5.1%) i/s - 602.448k

depth is always 0, so the index will always be false. No reason to
create the instance variable if it isn't used

|

As far as I can tell nobody is setting this variable.
|
| | |

| | |
| | |

`@reflects_state[depth+1]` will always be nil because we haven't made a
method call that would make it true yet.

Various behaviors needed by associations (such as creating the through
record) are lost when `where` is called, since we stop having a
`CollectionProxy` and start having an `AssociationRelation` which does
not contain this behavior. I *think* we should be able to rm
`AssociationRelation`, but we have tests saying the changes required to
do that would be bad (Without saying why. Of course. >_>)
Fixes #19073.

Rely on through table name in has_many fixtures

| | | |
| | | |

Rather than using the association's join_table method, which
constructs a table name from conventions, this should rely on the
through reflection's table_name to be resilient to tables that were
not automatically named.

[Toby Ovod-Everett & Andrey Nering & Yves Senn]
Closes #17726.
Closes #10939.
This patch makes three distinct modifications:
1. no longer fall back to disabling user triggers if system triggers can't be disabled
2. warn the user when referential integrity can't be disabled
3. restore aborted transactions when referential integrity can't be disabled
The motivation behind these changes is to make the behavior of Rails
transparent and less error-prone. To require superuser privileges is not optimal
but it's what Rails currently needs. Users who absolutely rely on disabling user triggers
can patch `disable_referential_integrity`.
We should investigate `SET CONSTRAINTS` as a possible solution which does not require
superuser privileges.

Only `primary_key` should be extracted by d47357e in #19030, but
`new_coclumn_definition` was also extracted because #17631 is merged
previously, then #19030 is auto merged without conflicts.
This commit is for move back `new_column_definition` into
`TableDefinition`.
