|\ \ \ | | | | | | | | Explain that default_scope also influences update_all
| * | | Reword documentation for update_allRené van den Berg2014-11-241-8/+1
| | | | | | | | | | | | It now contains a carefully formulated reference to the "current relation" which might help clarify that the receiving will generate its own scope, escaping the need for explicitly referencing `default_scope` which is, after all, just another way of specifying a scope and nothing special.
| * | | Explain that default_scope also influences update_allRené van den Berg2014-11-201-5/+12
| | | | | | | | | | | | | | | | | | | | This was not explicitly stated before and I needed to try it out to be certain. A little explicit statement in the API docs might help here.
* | | | Mark comments that should not be in the docsclaudiob2014-11-244-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some comments that are meant to separate blocks of code in a file show up on http://api.rubyonrails.org as though they were part of the documentation. This commit hides those comments from the documentation. Stems from the discussion with @zzak at https://github.com/voloko/sdoc/issues/79#issuecomment-64158738 [ci skip]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason changing `.find` to `.unscoped.find` in https://github.com/rails/rails/commit/f766abd4cf3eb75469d3646cfb6d85e668c619f3 caused `scoping` to leak in some tests when run in isolation (looks like a concurrency issue?). `relation_scoping_test.rb` is a case that failed. From what I can tell it should not be possible, but changing to the block form fixes it. There is a deeper issue that I can't seem to find. /cc @senny

| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 6f7910a and 52c70d4. Query params are type cased through the same method, so this approach doesn't work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We added a comparison to "id", and call to `self.class.primary_key` a *lot*. We also have performance hits from `&block` all over the place. We skip the check in a new method, in order to avoid breaking the behavior of `read_attribute`

| | | | | | | | | | | | This caused a pretty major performance regression for 4.2, as this is a hotspot for query construction. We're still slightly slower than 4.1, but it's much less significant.

* | Allow `LazyAttributeHash` to be marshalledSean Griffin2014-11-141-13/+17
| | | | | | | | | | | | | | | | `default_proc` makes a hash unmarshallable, and adds unneccessary overhead. Since we control all access to the hash, let's just handle it in that method. This has the side effect of improving performance on initialization (but not neccessarily on access). We'll need to profile further once the tests are passing.
* | Correctly determine if an attribute is uninitializedSean Griffin2014-11-141-1/+1
| | | | | | | | | | | | | | In real usage, we give the builder a types hash with a default value of `Type::Value.new`. This means we need to explicitly check for the key, rather than the truthiness of the type to determine if it's a known but uninitialized attribute
* | Reduce the amount of work performed when instantiating AR modelsSean Griffin2014-11-145-27/+70
| | | | | | | | | | | | | | | | | | | | We don't know which attributes will or won't be used, and we don't want to create massive bottlenecks at instantiation. Rather than doing *any* iteration over types and values, we can lazily instantiate the object. The lazy attribute hash should not fully implement hash, or subclass hash at any point in the future. It is not meant to be a replacement, but instead implement its own interface which happens to overlap.
