* | Simplify and speed up Postgres query for primary_keysJordan Lewis2017-02-091-10/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | primary_keys(table) needs to query various metadata tables in Postgres to determine the primary key for the table. Previously, it did so using a complex common table expression against pg_constraint and pg_attribute. This patch simplifies the query by joining pg_index against pg_attribute instead of going through pg_constraint. This avoids an expensive unnest, window function query, and common table expression. EXPLAINing these queries in Postgres against a database with a single table with a composite primary key shows a 66% reduction in the plan and execute latencies. This is significant during application startup time, especially against very large schemas, where these queries would be even slower and more numerous. Closes #27949
* | Refactor `ColumnDefinition` to contain `options` hashRyuta Kamizono2017-02-0911-109/+50
| | | | | | | | | | | | Column options are passed as an hash args then used as `options` hash in `add_column_options!`. Converting args to attributes is inconvinient for using options as an hash.

* | Fix collection_singular_ids= bugDaniel Colson2017-02-021-2/+2
| | | | | | | | | | | | | | | | | | When the association's primary key is manually set as a symbol and called with an array of strings, CollectionAssociation#ids_writer fails to cast the ids to integers. This is because AssociationReflection#association_primary_key_type and ThroughReflection#association_primary_key_type return the incorrect type, since ModelSchema.type_for_attribute only accepts a string. The result is an ActiveRecord::RecordNotFound error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an alternative of #27714. If `has_one :through` association has set `nil`, `through_record` is destroyed but still remain loaded target in `through_proxy` until `reload` or `reset` explicitly. If `through_proxy` is not reset (remain destroyed (frozen) target), setting new record causes `RuntimeError: Can't modify frozen hash`. To prevent `RuntimeError`, should reload `through_record` that has been destroyed in `create_through_record`.

In this case, the reflection knows how to construct the right reflection for this join, so lets just construct that relation rather than instance execing to figure it out later.

Previously, it did so using a correlated subquery - a subquery that references results from the outer scope. This patch updates the query to remove the subquery in favor of a simpler and more efficient JOIN clause. Running the two queries through EXPLAIN against Postgres additionally shows that the original form with a correlated subquery requires a Nested Loop Left Join, while the new form with a simple JOIN can use a more efficient Merge Left Join.
