* Fix error message when trying to create an associated recordRafael Mendonça França2014-12-301-1/+1
| | | | | | | | | | | | This error only happens when the foreign key is missing. Before this fix the following exception was being raised: NoMethodError: undefined method `val' for #<Arel::Nodes::BindParam:0x007fc64d19c218> Now the message is: ActiveRecord::UnknownAttributeError: unknown attribute 'foreign_key' for Model.

| * PostgreSQL, Fix change detection caused by wrong data for bytea unescaping.Lars Kanis2014-12-291-0/+1
| | | | | | | | | | | | | | | | | | | | This showed up when running BinaryTest#test_load_save with the more restrictive input string handling of pg-0.18.0.pre20141117110243.gem . Bytea values sent to the server are in binary format, but are returned back as escaped text. To fulfill the assumption that type_cast_from_database(type_cast_for_database(binary)) == binary we unescape only, if the value was really received from the server.
* | Ensures that primary_key method will return nil when multi-pkArthur Neves2014-12-302-8/+7
| | | | | | | | | | | | | | When table has a composite primary key, the `primary_key` method for sqlite3 and postgresql was only returning the first field of the key. Ensures that it will return nil instead, as AR dont support composite pks.

| | | | | | | | | | | | | | | | | | ActiveRecord::Base `save` and `save!` take an option boolean `:touch` parameter since #18225 (stems from #18202). This commit document that parameter. [ci skip]

* | Remove all cases of manuallly wrapping `Arel::Nodes::Quoted`Sean Griffin2014-12-293-21/+4
| | | | | | | | | | | | | | | | | | | | This is no longer required now that we are injecting a type caster object into the Arel table, with the exception of uniqueness validations. Since it calls `ConnectionAdapter#type_cast`, the value has already been cast for the database. We don't want Arel to attempt to cast it further, so we need to continue wrapping it in a quoted node. This can potentially go away when this validator is refactored to make better use of `where` or the predicate builder.

| | | | | | | | | | | | | | This API will require much less consuming code to change to accomodate the removal of automatic type casting from Arel. As long as the predicates are constructed using the `arel_table` off of an AR subclass, there will be no changes that need to happen.

| | | | | | | | | We only support classes which provide a no-args constructor to use as a default value. We can provide a more helpful error message if we catch this when `serialize` is called, rather than letting it error when you try to assign the attribute. Fixes #18224

| | | | | | | Part of the larger refactoring to remove type casting from Arel. We can inform it that we already have the right type by wrapping the value in an `Arel::Nodes::Quoted`. This commit can be reverted when we have removed type casting from Arel in Rail 5.1

* Fall back to type casting from the connection adapterSean Griffin2014-12-261-2/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several valid cases where right now we can't determine the association's class in a call to `where`. In these cases, we can fall back to casting by looking up the column from the connection adapter (which is what happens right now when we fall through to Arel) This is ugly, and since we're trying to separate the concept of a type from a column, I'd like to remove it in the future. The problem basically comes down to this: Liquid.joins(molecules: :electrons) .where("molecules.name" => "something", "electrons.name" => "something") The hash in this case will turn into: { molecules: { name: "something" }, electrons: { name: "something" }, } What we actually need is: { molecules: { name: "something", electrons: { name: "something" }, } } /cc @mrgilman
* Go through normal `where` logic in uniqueness validationSean Griffin2014-12-261-4/+6
| | | | | | | This code could use some much heavier refactoring. It looks like `build_relation` duplicates most of the logic of `Relation#where` and `PredicateBuilder` with regards to handling associations and attribute aliases
* We don't need to cast the value a second time in uniqueness validationsSean Griffin2014-12-261-0/+1
| | | | | | | Part of the larger refactoring to remove type casting from Arel. Since we've already cast the value a few lines above, we don't need to re-cast it later. We can inform Arel of this by wrapping it in an `Arel::Nodes::Quoted`, which will no longer be required in Rails 5.1
* We don't need to perform type casting on the STI conditionSean Griffin2014-12-261-0/+1
| | | | | | | We will always have the correct type for this query, so no casting is needed. We inform Arel that we already have the right type by wrapping it in an `Arel::Nodes::Quoted` (which we will no longer need to do in Rails 5.1)
* Go through normal `where` logic when preloading associationsSean Griffin2014-12-261-1/+1
| | | | | | | | | | This will allow eager type casting to take place as needed. There doesn't seem to be any particular reason that the `in` statement was forced for single values, and the commit message where it was introduced gives no context. See https://github.com/rails/rails/commit/d90b4e2615e8048fdeffc6dffe3246704adee01f
* Eagerly cast array values passed to the predicate builderSean Griffin2014-12-261-1/+6

* Eagerly cast range values in the predicate builderSean Griffin2014-12-262-1/+25
| | | | | | | | | A custom object is required for this, as you cannot build a range object out of `Arel::Nodes::Quoted` objects. Depends on the changes introduced in https://github.com/rails/arel/commit/cf03bd45e39def057a2f63e42a3391b7d750dece /cc @mrgilman
* Perform casting of single values within the predicate builderSean Griffin2014-12-265-6/+37
| | | | | | | | | | | As part of the larger refactoring to remove type casting from Arel, we need to do the casting of values eagerly. The predicate builder is the closest place that knows about the Active Record class, and can therefore have the type information. /cc @mrgilman [Sean Griffin & Melanie Gilman]
* Remove `klass` and `arel_table` as a dependency of `PredicateBuilder`Sean Griffin2014-12-266-30/+69
| | | | | | | | | | | | | | | This class cares far too much about the internals of other parts of Active Record. This is an attempt to break out a meaningful object which represents the needs of the predicate builder. I'm not fully satisfied with the name, but the general concept is an object which represents a table, the associations to/from that table, and the types associated with it. Many of these exist at the `ActiveRecord::Base` class level, not as properties of the table itself, hence the need for another object. Currently it provides these by holding a reference to the class, but that will likely change in the future. This allows the predicate builder to remain wholy concerned with building predicates. /cc @mrgilman
* Refactor association handling in `PredicateBuilder`Sean Griffin2014-12-262-21/+61
| | | | | | | | | | I'm attempting to remove `klass` as a dependency of the predicate builder, in favor of an object that better represents what we're using it for. The only part of this which doesn't fit nicely into that picture is the check for an association being polymorphic. Since I'm not yet sure what that is going to look like, I've moved this logic into another class in an attempt to separate things that will change from things that won't.
* Re-use the predicate builder in the `ArrayHandler`Sean Griffin2014-12-262-8/+16
| | | | | | | | | | This reduces the number of places which will need to care about single value or range specific logic as we introduce type casting. The array handler is only responsible for producing `in` statements. /cc @mrgilman [Sean Griffin & Melanie Gilman]
* Change `PredicateBuilder` handler methods to instance methodsSean Griffin2014-12-265-30/+71
| | | | | | | | | | | | This will allow us to pass the predicate builder into the constructor of these handlers. The procs had to be changed to objects, because the `PredicateBuilder` needs to be marshalable. If we ever decide to make `register_handler` part of the public API, we should come up with a better solution which allows procs. /cc @mrgilman [Sean Griffin & Melanie Gilman]
* Add missing `:nodoc:`Sean Griffin2014-12-261-1/+1

* Inject the `PredicateBuilder` into the `Relation` instanceSean Griffin2014-12-269-16/+24
| | | | | | | Construction of relations can be a hotspot, we don't want to create one of these in the constructor. This also allows us to do more expensive things in the predicate builder's constructor, since it's created once per AR::Base subclass
