* Add a public API to allow users to specify column typesSean Griffin2014-05-261-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | As a result of all of the refactoring that's been done, it's now possible for us to define a public API to allow users to specify behavior. This is an initial implementation so that I can work off of it in smaller pieces for additional features/refactorings. The current behavior will continue to stay the same, though I'd like to refactor towards the automatic schema detection being built off of this API, and add the ability to opt out of automatic schema detection. Use cases: - We can deprecate a lot of the edge cases around types, now that there is an alternate path for users who wish to maintain the same behavior. - I intend to refactor serialized columns to be built on top of this API. - Gem and library maintainers are able to interact with `ActiveRecord` at a slightly lower level in a more stable way. - Interesting ability to reverse the work flow of adding to the schema. Model can become the single source of truth for the structure. We can compare that to what the database says the schema is, diff them, and generate a migration.
* Fixed serialization for records with an attribute named `format`.Godfrey Chan2014-05-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * * * This bug can be triggered when serializing record R (the instance) of type C (the class), provided that the following conditions are met: 1. The name of one or more columns/attributes on C/R matches an existing private method on C (e.g. those defined by `Kernel`, such as `format`). 2. The attribute methods have not yet been generated on C. In this case, the matching private methods will be called by the serialization code (with no arguments) and their return values will be serialized instead. If the method requires one or more arguments, it will result in an `ArgumentError`. This regression is introduced in d1316bb. * * * Attribute methods (e.g. `#name` and `#format`, assuming the class has columns named `name` and `format` in its database table) are lazily defined. Instead of defining them when a the class is defined (e.g. in the `inherited` hook on `ActiveRecord::Base`), this operation is deferred until they are first accessed. The reason behind this is that is defining those methods requires knowing what columns are defined on the database table, which usually requires a round-trip to the database. Deferring their definition until the last-possible moment helps reducing unnessary work, especially in development mode where classes are redefined and throw away between requests. Typically, when an attribute is first accessed (e.g. `a_book.format`), it will fire the `method_missing` hook on the class, which triggers the definition of the attribute methods. This even works for methods like `format`, because calling a private method with an explicit receiver will also trigger that hook. Unfortunately, `read_attribute_for_serialization` is simply an alias to `send`, which does not respect method visibility. As a result, when serializing a record with those conflicting attributes, the `method_missing` is not fired, and as a result the attribute methods are not defined one would expected. Before d1316bb, this is negated by the fact that calling the `run_callbacks` method will also trigger a call to `respond_to?`, which is another trigger point for the class to define its attribute methods. Therefore, when Active Record tries to run the `after_find` callbacks, it will also define all the attribute methods thus masking the problem. * * * The proper fix for this problem is probably to restrict `read_attribute_for_serialization` to call public methods only (i.e. alias `read_attribute_for_serialization` to `public_send` instead of `send`). This however would be quite risky to change in a patch release and would probably require a full deprecation cycle. Another approach would be to override `read_attribute_for_serialization` inside Active Record to force the definition of attribute methods: def read_attribute_for_serialization(attribute) self.class.define_attribute_methods send(attribute) end Unfortunately, this is quite likely going to cause a performance degradation. This patch therefore restores the behaviour from the 4-0-stable branch by explicitly forcing the class to define its attribute methods in a similar spot (when records are initialized). This should not cause any extra roundtrips to the database because the `@columns` should already be cached on the class. Fixes #15188.

* Fix polymorphic eager load with foreign_key as String.Lauro Caetano2014-05-201-0/+3
| | | | | | | | | The foreign_key could be `String` and just doing `owners_map[owner_key]` could return `nil`. To prevent this bug, we should `to_s` both keys if their types are different. Fixes #14734.

| | | | | | | | | | | | Changed the call to a scope block to be evaluated with instance_eval. The result is that ScopeRegistry can use the actual class instead of base_class when caching scopes so queries made by classes with a common ancestor won't leak scopes.

See this snippet from the PG docs: Tip: There is no performance difference among these three types, apart from increased storage space when using the blank-padded type, and a few extra CPU cycles to check the length when storing into a length-constrained column. While character(n) has performance advantages in some other database systems, there is no such advantage in PostgreSQL; in fact character(n) is usually the slowest of the three because of its additional storage costs. In most situations text or character varying should be used instead.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was causing error when using `with_options` passing a lambda as its last argument. class User < ActiveRecord::Base with_options dependent: :destroy do |assoc| assoc.has_many :profiles, -> { where(active: true) } end end It was happening because the `option_merger` was taking the last argument and checking if it was a Hash. This breaks the HasMany usage, because its last argument can be a Hash or a Proc. As the behavior described in this test: https://github.com/rails/rails/blob/master/activesupport/test/option_merger_test.rb#L69 the method will only accept the lambda, this way it will keep the expected behavior.

The problem is that `method_defined_within?(name, klass, superklass)` only works correclty when `klass` and `superklass` are both `Class`es. If both `klass` and `superklass` are both `Class`es, they share the same inheritance chain, so if a method is defined on `klass` but not `superklass`, this method must be introduced at some point between `klass` and `superklass`. This does not work when `superklass` is a `Module`. A `Module`'s inheritance chain contains just itself. So if a method is defined on `klass` but not on `superklass`, the method could still be defined somewhere upstream, e.g. in `Object`. This fix works by avoiding calling `method_defined_within?` with a module while still fufilling the requirement (checking that the method is defined withing `superclass` but not is not a generated attribute method). 4d8ee288 is likely an attempted partial fix for this problem. This unrolls that fix and properly check the `superclass` as intended. Fixes #11569.

* Building new records with enum scopes now works as expectedGodfrey Chan2014-01-031-4/+0
| | | | | | | | | | | | | | | | | | | | | | Previously, this would give an `ArgumentError`: class Issue < ActiveRecord::Base enum :status, [:open, :finished] end Issue.open.build # => ArgumentError: '0' is not a valid status Issue.open.create # => ArgumentError: '0' is not a valid status PR #13542 muted the error, but the issue remains. This commit fixes the issue by allowing the enum value to be written directly via the setter: Issue.new.status = 0 # This now sets status to :open Assigning a value directly via the setter like this is not part of the documented public API, so users should not rely on this behavior. Closes #13530.
* Fix the enums writer methodsRobin Dupret2014-01-011-0/+4
| | | | | | | | | | | Previously, the writer methods would simply check whether the passed argument was the symbol representing the integer value of an enum field. Therefore, it was not possible to specify the numeric value itself but the dynamically defined scopes generate where clauses relying on this kind of values so a chained call to a method like `find_or_initialize_by` would trigger an `ArgumentError`.

| | | | | | | | | | | Currently `scope_chain` uses same array for building different `scope_chain` for different associations. During processing these arrays are sometimes mutated and because of in-place mutation the changed `scope_chain` impacts other reflections. Fix is to dup the value before adding to the `scope_chain`. Fixes #3882.

* Prevent Relation#merge from collapsing wheres on the RHSJon Leighton2013-01-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This caused a bug with the new associations implementation, because now association conditions are represented as Arel nodes internally right up to when the whole thing gets turned to SQL. In Rails 3.2, association conditions get turned to raw SQL early on, which prevents Relation#merge from interfering. The current implementation was buggy when a default_scope existed on the target model, since we would basically end up doing: default_scope.merge(association_scope) If default_scope contained a where(foo: 'a') and association_scope contained a where(foo: 'b').where(foo: 'c') then the merger would see that the same column is representated on both sides of the merge and collapse the wheres to all but the last: where(foo: 'c') Now, the RHS of the merge is left alone.
