* Create a blacklist to disallow mutator methods to be delegated to `Array`.Lauro Caetano2013-12-171-4/+11
| | | | | | | | This change was necessary because the whitelist wouldn't work. It would be painful for users trying to update their applications. This blacklist intent to prevent odd bugs and confusion in code that call mutator methods directely on the `Relation`.
* Better support for `where()` conditions that use an association name.Martin Emde2013-12-161-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the name of an association in `where` previously worked only if the value was a single `ActiveRecrd::Base` object. e.g. Post.where(author: Author.first) Any other values, including `nil`, would cause invalid SQL to be generated. This change supports arguments in the `where` query conditions where the key is a `belongs_to` association name and the value is `nil`, an `Array` of `ActiveRecord::Base` objects, or an `ActiveRecord::Relation` object. # Given the Post model class Post < ActiveRecord::Base belongs_to :author end # nil value finds records where the association is not set Post.where(author: nil) # SELECT "posts".* FROM "posts" WHERE "posts"."author_id" IS NULL # Array values find records where the association foreign key # matches the ids of the passed ActiveRecord models, resulting # in the same query as Post.where(author_id: [1,2]) authors_array = [Author.find(1), Author.find(2)] Post.where(author: authors_array) # ActiveRecord::Relation values find records using the same # query as Post.where(author_id: Author.where(last_name: "Emde")) Post.where(author: Author.where(last_name: "Emde")) Polymorphic `belongs_to` associations will continue to be handled appropriately, with the polymorphic `association_type` field added to the query to match the base class of the value. This feature previously only worked when the value was a single `ActveRecord::Base`. class Post < ActiveRecord::Base belongs_to :author, polymorphic: true end Post.where(author: Author.where(last_name: "Emde")) # Generates a query similar to: Post.where(author_id: Author.where(last_name: "Emde"), author_type: "Author")

* | Fix ActiveRecord::Relation#unscopeJon Leighton2013-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm pretty confused about the addition of this method. The documentation says that it was intended to allow the removal of values from the default scope (in contrast to #except). However it behaves exactly the same as except: https://gist.github.com/jonleighton/7537008 (other than having a slightly enhanced syntax). The removal of the default scope is allowed by 94924dc32baf78f13e289172534c2e71c9c8cade, which was not a change we could make until 4.1 due to the need to deprecate things. However after that change #unscope still gives us nothing that #except doesn't already give us. However there *is* a desire to be able to unscope stuff in a way that persists across merges, which would allow associations to be defined which unscope stuff from the default scope of the associated model. E.g. has_many :comments, -> { unscope where: :trashed } So that's what this change implements. I've also corrected the documentation. I removed the guide references to #except as I think unscope really supercedes #except now. While we're here, there's also a potential desire to be able to write this: has_many :comments, -> { unscoped } However, it doesn't make sense and would not be straightforward to implement. While with #unscope we're specifying exactly what we want to be removed from the relation, with "unscoped" we're just saying that we want it to not have some things which were added earlier on by the default scope. However in the case of an association, we surely don't want *all* conditions to be removed, otherwise the above would just become "SELECT * FROM comments" with no foreign key constraint. To make the above work, we'd have to somehow tag the relation values which get added when evaluating the default scope in order to differentiate them from other relation values. Which is way too much complexity and therefore not worth it when most use cases can be satisfied with unscope. Closes #10643, #11061.

* Allow methods arity below -1 in assert_responds.Federico Ravasio2013-10-081-3/+4
| | | | | | | | Every method from MRI's core classes is written in C. This means Method#arity always returns -1 for methods with a variable number of arguments. This is not the case with Rubinius, where, for example Array#slice! is implemented in Ruby and has arity -2, since is defined as def slice!(start, length = undefined)

| * Deprecate the delegation of Array bang methods in ActiveRecord::DelegationBen Woosley2013-09-041-0/+97
| | | | | | | | | | | | | | | | | | | | | | The primary means of returning results for Array bang methods is to modify the array in-place. When you call these methods on a relation, that array is created, modified, and then thrown away. Only the secondary return value is exposed to the caller. Removing this delegation is a straight-forward way to reduce user error by forcing callers to first explicitly call #to_a in order to expose the array to be acted on by the bang method.

* Add ability to specify how a class is converted to Arel predicatesgrif2013-07-281-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability for rails apps or gems to have granular control over how a domain object is converted to sql. One simple use case would be to add support for Regexp. Another simple case would be something like the following: class DateRange < Struct.new(:start, :end) def include?(date) (start..end).cover?(date) end end class DateRangePredicate def call(attribute, range) attribute.in(range.start..range.end) end end ActiveRecord::PredicateBuilder.register_handler(DateRange, DateRangePredicate.new) More complex cases might include taking a currency object and converting it from EUR to USD before performing the query. By moving the existing handlers to this format, we were also able to nicely refactor a rather nasty method in PredicateBuilder.
* Handle aliased attributes in ActiveRecord::Relation.Godfrey Chan2013-05-011-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | When using symbol keys, ActiveRecord will now translate aliased attribute names to the actual column name used in the database: With the model class Topic alias_attribute :heading, :title end The call Topic.where(heading: 'The First Topic') should yield the same result as Topic.where(title: 'The First Topic') This also applies to ActiveRecord::Relation::Calculations calls such as `Model.sum(:aliased)` and `Model.pluck(:aliased)`. This will not work with SQL fragment strings like `Model.sum('DISTINCT aliased')`. Github #7839 *Godfrey Chan*

* Rollback where.like and where.not_likeCarlos Antonio da Silva2012-12-071-17/+2
| | | | | | | | | | | | | | | | | | | The real win with these chain methods is where.not, that takes care of different scenarios in a graceful way, for instance when the given value is nil. where("author.id != ?", author_to_ignore.id) where.not("author.id", author_to_ignore.id) Both where.like and where.not_like compared to the SQL versions doesn't seem to give us that much: Post.where("title LIKE 'ruby on%'") Post.where.like(title: 'ruby on%'") Post.where("title NOT LIKE 'ruby on%'") Post.where.not_like(title: 'ruby on%'") Thus Rails is adding where.not, but not where.like/not_like and others.
