* Refactor a bitJon Leighton2012-08-011-38/+37
| | | | | This doesn't change the exernal behavior, but it moves some code around to where I think it properly belongs.
* Add `Relation#load`Jon Leighton2012-08-011-2/+12
| | | | | | | | | | | | | This method explicitly loads the records and then returns `self`. Rather than deciding between "do I want an array or a relation?", most people are actually asking themselves "do I want to eager load or lazy load?" Therefore, this method provides a way to explicitly eager-load without having to switch from a `Relation` to an array. Example: @posts = Post.where(published: true).load

* Load all records in Relation#inspectJon Leighton2012-07-071-4/+1
| | | | | | | | | | | | | | | | | | | A test was failing due to the way that Relation#inspect causes association proxies to ignore unsaved records added to the association. This is fixed by simply calling to_a and letting to_a figure out how to get the records (which, in the case of associations, takes into account new records). I think it is acceptable to do this rather than limiting the query at the database level: * It's what we've done in all released Rails versions up to this point * The goal of the limit is to not flood the console with output - this is the problem we're targeting, rather than the actual loading of the records from the database * You probably want to do something with those records later anyway, otherwise you wouldn't have built a relation for them.
* Relation#inspect handles doesn't perform a new query on an already-loaded ↵Jon Leighton2012-07-071-1/+4

* Limit the number of records in Relation#inspectDamien Mathieu2012-07-061-1/+13
| | | | While it's interesting to have the results array, it can make a console or a webpage freeze if there are a lot of them. So this limits the number of records displayed in #inspect to 10 and tells how much were effectively found.
* Show the records in Relation#inspectJon Leighton2012-07-061-0/+4
| | | | | | | | | | | | | | | | | The reason for removing the previous implementation of `#inspect` was that it hid from you that you were dealing with a `Relation` rather than an `Array`. But it is still useful to be able to see the records, particularly if you're writing something like the following in tests: assert_equal [foo], Post.where(:bar) If the assertion fails, you want to see what records were actually loaded. So this implementation makes it clear that you've got a `Relation`, but also shows your records.

* implements a much faster auto EXPLAIN, closes #3843 [José Valim & Xavier Noria]Xavier Noria2011-12-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | This commit vastly reduces the impact of auto explain logging when enabled, while keeping a negligible cost when disabled. The first implementation was based on the idea of subscribing to "sql.active_record" when needed, and unsubscribing once done. This is the idea behind AR::Relation#explain. Subscribe, collect, unsubscribe. But with the current implementation of notifications unsubscribing is costly, because it wipes an internal cache and that puts a penalty on the next event. So we are switching to an approach where a long-running subscriber is listening. Instead of collecting the queries with a closure in a dedicated subscriber, now we setup a thread local. If the feature is disabled by setting the threshold to nil, the subscriber will call a method that does nothing. That's totally cheap.
