* Improve where.not docs [ci skip]Carlos Antonio da Silva2012-12-081-14/+8
| | | | | | | * Fix example queries * Remove doc entries of where.like/not_like. * Remove :chain from where.not related docs. To me that's an implementation detail and we don't expect people to use where(:chain).not.
* Update AR Changelog with correct example using includesCaike Souza2012-12-081-4/+4
| | | | These queries don't seem to work without the includes clause. [ci skip]
* Rollback where.like and where.not_likeCarlos Antonio da Silva2012-12-073-46/+4
| | | | | | | | | | | | | | | | | | | 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.
* Document the types of arguments accepted by AR#notclaudiob2012-12-072-2/+23
| | | | | | | | This commit stems from https://github.com/rails/rails/pull/8332#issuecomment-11127957 Since the formats in which conditions can be passed to `not` differ from the formats in which conditions can be passed to `like` and `not_like`, then I think it's worth adding rdoc and tests to show this behavior
* revises a RDoc example to make it idiomaticXavier Noria2012-12-071-8/+8
| | | | | | The force flag suggests the original was probably copied from some db/schema.rb. Thanks to Josh Susser for spotting and reporting this.
* Fix where.not with in clauseCarlos Antonio da Silva2012-12-072-4/+4
| | | | | | Arel::Nodes::In inherits from Arel::Nodes::Equality, so the case statement was always using the Equality operator for both scenarios, resulting in a not equal query instead.
* Update #where rdoc to match 6ba0f97 [ci skip]claudiob2012-12-071-4/+4
| | | | | | | | This commit updates the rdoc of AR#where to match the changes applied in https://github.com/rails/rails/commit/6ba0f97 that is: * `where(nil)` has the same effect of `where('')`: a no op * `where` (no args) has the same effect of `where(:chain)`: to create a WhereChain
* Move where with blank conditions test to the correct where tests fileCarlos Antonio da Silva2012-12-072-6/+6
| | | | This test does not belong to has many associations test.
* Ensure there won't be any regression with where(nil) callsCarlos Antonio da Silva2012-12-072-5/+5
| | | | | | | | | | | | | | | | | | | Consider this scenario: if params[:foo] conditions = { foo: true } end foos = Foo.where(conditions).order(:id) When params[:foo] is nil, this would call: foos = Foo.where(nil).order(:id) In this scenario, we want Foo.where(conditions) to be the same as calling Foo.all, otherwise we'd get a "NoMethodError order for WhereChain". Related to #8332.

* | Unscope update_column(s) query to ignore default scopeCarlos Antonio da Silva2012-12-063-1/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When applying default_scope to a class with a where clause, using update_column(s) could generate a query that would not properly update the record due to the where clause from the default_scope being applied to the update query. class User < ActiveRecord::Base default_scope where(active: true) end user = User.first user.active = false user.save! user.update_column(:active, true) # => false In this situation we want to skip the default_scope clause and just update the record based on the primary key. With this change: user.update_column(:active, true) # => true Fixes #8436.

* | | Replace comments' non-breaking spaces with spacesclaudiob2012-12-043-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes, on Mac OS X, programmers accidentally press Option+Space rather than just Space and don’t see the difference. The problem is that Option+Space writes a non-breaking space (0XA0) rather than a normal space (0x20). This commit removes all the non-breaking spaces inadvertently introduced in the comments of the code.

The compiled methods apply to all subsequent Relation instances. This creates several problems: 1) After Post.all.recent has been called, User.all.respond_to?(:recent) will be true, even if User.all.recent will actually raise an error due to no User.recent method existing. (See #8080.) 2) Depending on the AR class, the delegation should do different things. For example, if a Post.zip method exists, then Post.all.zip should call it. But this will then result in User.zip being called by a subsequent User.all.zip, even if User.zip does not exist, when in fact User.all.zip should call User.all.to_a.zip. (There are various variants of this problem.) We are creating these compiled delegations in order to avoid method missing and to avoid repeating logic on each invocation. One way of handling these issues is to add additional checks in various places to ensure we're doing the "right thing". However, this makes the compiled methods signficantly slower. In which case, there's almost no point in avoiding method_missing at all. (See #8127 for a proposed solution which takes this approach.) This is an alternative approach which involves creating a subclass of ActiveRecord::Relation for each AR class represented. So, with this patch, Post.all.class != User.all.class. This means that the delegations are compiled for and only apply to a single AR class. A compiled method for Post.all will not be invoked from User.all. This solves the above issues without incurring significant performance penalties. It's designed to be relatively seamless, however the downside is a bit of complexity and potentially confusion for a user who thinks that Post.all and User.all should be instances of the same class.

However, we can conclude that Relation construction has become a little slower (as we'd expect), but not by a huge huge amount, and we can still construct a large number of Relations quite quickly.
