| | | | | | | | | | | | | | | | | | | | | | | | Using ActiveRecord::Base.attribute to declare an attribute with a default value on a model where the attribute is not backed by the database would raise a NotImplementedError when model.save is called. The error originates from https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L84. This is called from https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L46 on an ActiveRecord::Attribute::Null object. This commit corrects the behavior by implementing ActiveRecord::Attribute::Null#type_cast. With ActiveRecord::Attribute::Null#type_cast defined, ActiveRecord::Attribute::Null#value (https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L173..L175) can be replaced with its super method (https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L36..L40). fixes #24979
* | remove_connection should not remove parent connectionArthur Neves2016-05-111-0/+7
|/ | | | | | When calling remove_connection in a subclass, that should not fallback to the parent, otherwise it will remove the parent connection from the handler.
* Dont cache the conn_spec_name when emptyArthur Neves2016-05-111-1/+10
| | | | | | | | We cannot cache the connection_specification_name when it doesnt exist. Thats because the parent value could change, and we should keep failling back to the parent. If we cache that in a children as an ivar, we would not fallback anymore in the next call, so the children would not get the new parent spec_name.
* Make sure we reset the connection_specification_name onArthur Neves2016-05-101-0/+14
| | | | | | | | | | | | | | remove_connection When calling `remove_connection` on a model, we delete the pool so we also need to reset the `connection_specification_name` so it will fallback to the parent. This was the current behavior before rails 5, which will fallback to the parent connection pool. [fixes #24959] Special thanks to @jrafanie for working with me on this fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ConnectionHandler will not have any knowlodge of AR models now, it will only know about the specs. Like that we can decouple the two, and allow the same model to use more than one connection. Historically, folks used to create abstract AR classes on the fly in order to have multiple connections for the same model, and override the connection methods. With this, now we can override the `specificiation_id` method in the model, to return a key, that will be used to find the connection_pool from the handler.

* / Allow the connection adapters to determine the order of bind paramsSean Griffin2016-05-061-0/+18
|/ | | | | | | | | | | | In 5.0 we use bind parameters for limit and offset, while in 4.2 we used the values directly. The code as it was written assumed that limit and offset worked as `LIMIT ? OFFSET ?`. Both Oracle and SQL Server have a different syntax, where the offset is stated before the limit. We delegate this behavior to the connection adapter so that these adapters are able to determine how the bind parameters are flattened based on what order their specification has the various clauses appear.

| | | | | | | | | | Unlike `one?` and `none?`, `empty?` has interactions with methods outside of enumerable. It also doesn't fit in the same vein. `Topic.any?` makes sense. `Topic.empty?` does not, as `Topic` is not a container. Fixes #24808 Close #24812

| * https://github.com/rails/rails/commit/42dd2336b31a8d98776d039a2b9fd7f834156a ↵Vipul A M2016-04-231-0/+18
| | | | | | | | | | | | | | | | | | 78 changed INSERT INTO versions to run in 1 single query. This breaks for sqlite versions < 3.7.11, which is especially the case on Ubuntu 12.04 LTS, that has SQLite version 3.7.9 as default. So we check for support for multi insert, before performing single query inserts, else fallback to older version of running multiple queries. [Vipul A M & Yasuo Honda]
* | Do not attempt to return connection with open transaction to pool (#24610)Sean Griffin2016-04-221-5/+7
|/ | | | | | | | | | | | | When the query cache completes, if Active Record is still inside of a transaction, it is because the transaction is meant to be left open above this unit of work (such as transactional fixtures in tests). There were several tests around the behavior of "tests" that were invalid, as tests are not run through the executor. They have been changed to reflect the new behavior, which is closer to what actually occurs in Rails tests. Fixes #23989 Fixes #24491 Close #24500
