* make node search more efficientAaron Patterson2013-10-091-0/+4
| | | | | | Rather than search every node in the tree, comparing that node and all of its parents every time, start at the root from both sides and work our way down the tree

* push parent up to the superclassAaron Patterson2013-10-091-6/+1
| | | | We always want a linked list back to the root node.

* decouple JoinAssociation from JoinDependencyAaron Patterson2013-10-081-9/+4
|
* Set the join type on constructionAaron Patterson2013-10-031-2/+2
| | | | | We always set the join type immediately after construction, just make it part of the constructor and we can skip that step

* Apply default scope when joining associations.Jon Leighton2013-06-281-0/+2
| | | | | | | | | | | | | | | | | | | For example: class Post < ActiveRecord::Base default_scope -> { where published: true } end class Comment belongs_to :post end When calling `Comment.join(:post)`, we expect to receive only comments on published posts, since that is the default scope for posts. Before this change, the default scope from `Post` was not applied, so we'd get comments on unpublished posts.

* While merging relations preserve context for joinsJared Armstrong and Neeraj Singh2013-04-101-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes #3002. Also see #5494. ``` class Comment < ActiveRecord::Base belongs_to :post end class Author < ActiveRecord::Base has_many :posts end class Post < ActiveRecord::Base belongs_to :author has_many :comments end ``` `Comment.joins(:post).merge(Post.joins(:author).merge(Author.where(:name => "Joe Blogs"))).all` would fail with `ActiveRecord::ConfigurationError: Association named 'author' was not found on Comment`. It is failing because `all` is being called on relation which looks like this after all the merging: `{:joins=>[:post, :author], :where=>[#<Arel::Nodes::Equality: ....}`. In this relation all the context that `Post` was joined with `Author` is lost and hence the error that `author` was not found on `Comment`. Ths solution is to build JoinAssociation when two relations with join information are being merged. And later while building the arel use the previously built `JoinAssociation` record in `JoinDependency#graft` to build the right from clause. Thanks to Jared Armstrong (https://github.com/armstrjare) for most of the work. I ported it to make it compatible with new code base.
* changed variable name active_record => base_klassNeeraj Singh2013-04-091-1/+1
| | | | | | | | | | | | | | | | | Current code stores the klass name in active_record and this is used throughout. While reviewing the code time and again I had the mental picture of active_record being an instance of a klass. However here the actual klass is being stored in @active_record. Secondly at two different places while referring to @active_record the comment refers to it as base klass. All this points to active_record being not the best variable name. So I thought it is better to replace active_record with base_klass. This change is confined to JoinDependency, JoinBase, JoinPart and JoinAssociation - all joining related work.
