This reverts commit 761bc751d31c22e2c2fdae2b4cdd435b68b6d783.
This commit wasn't fixing any issue just using the same table for
different models with different primary keys.
|
| |
|
|
|
|
| |
Closes #6960

In some circumstances engine was Arel::Table.engine which for separate
reasons was an ActiveRecord::Model::DeprecationProxy, which caused a
deprecation warning.
In any case, we want the actual model class here, since we want to use
it to infer information about associations.
|
| |
|
|
|
|
|
| |
Previously the reflection would be looked up on the wrong class. However
the test passed because the examples referred back to themselves.
|
|
|
|
|
|
|
|
|
|
|
|
|

Allows you to specify the model association key in a belongs_to
relationship instead of the foreign key.
The following queries are now equivalent:
Post.where(:author_id => Author.first)
Post.where(:author => Author.first)
PriceEstimate.where(:estimate_of_type => 'Treasure', :estimate_of_id => treasure)
PriceEstimate.where(:estimate_of => treasure)
|

This is a cleaner version of #6916.
Closes #3165.

This is a real fix (as compared to the band-aid in b127d86c), which uses
the recently-added equality methods for ARel nodes. It has the side
benefit of simplifying the merge code a bit.
|
|
|
|
|
|
|
|
|
| |
This is at best a band-aid for a more proper fix, since it won't truly
handle the removal of the previous equality condition of these other
nodes. I'm planning to put in some work on ARel toward supporting that
goal.

This was requested by DHH to allow creating of one's own custom
association macros.
For example:
module Commentable
def has_many_comments(extra)
has_many :comments, -> { where(:foo).merge(extra) }
end
end
class Post < ActiveRecord::Base
extend Commentable
has_many_comments -> { where(:bar) }
end

User.order("name asc").order("created_at desc")
# SELECT * FROM users ORDER BY created_at desc, name asc
This also affects order defined in `default_scope` or any kind of associations.

This reverts commit 14fc8b34521f8354a17e50cd11fa3f809e423592.
Reason: we need to discuss a better path from this removal.

It has been moved to active_record_deprecated_finders.
Use #to_a instead.
|
|
|
|
|
|
|
| |
It doesn't serve much purpose now that ActiveRecord::Base.all returns a
Relation.
The code is moved to active_record_deprecated_finders.

Reason: all *_value methods are defined dynamically and so don't appear
in the documentation.
