* Move non-type objects into the `Type::Helpers` namespaceSean Griffin2015-02-074-4/+4
| | | | | | | The type code is actually quite accessible, and I'm planning to encourage people to look at the files in the `type` folder to learn more about how it works. This will help reduce the noise from code that is less about type casting, and more about random AR nonsense.
* Allow a symbol to be passed to `attribute`, in place of a type objectSean Griffin2015-02-063-1/+54
| | | | | | | | | | | | | | | | | | The same is not true of `define_attribute`, which is meant to be the low level no-magic API that sits underneath. The differences between the two APIs are: - `attribute` - Lazy (the attribute will be defined after the schema has loaded) - Allows either a type object or a symbol - `define_attribute` - Runs immediately (might get trampled by schema loading) - Requires a type object This was the last blocker in terms of public interface requirements originally discussed for this feature back in May. All the implementation blockers have been cleared, so this feature is probably ready for release (pending one more look-over by me).

* rm `Column#cast_type`Sean Griffin2015-02-033-18/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The type from the column is never used, except when being passed to the attributes API. While leaving the type on the column wasn't necessarily a bad thing, I worry that it's existence there implies that it is something which should be used. During the design and implementation process of the attributes API, there have been plenty of cases where getting the "right" type object was hard, but I had easy access to the column objects. For any contributor who isn't intimately familiar with the intents behind the type casting system, grabbing the type from the column might easily seem like the "correct" thing to do. As such, the goal of this change is to express that the column is not something that should be used for type casting. The only places that are "valid" (at the time of this commit) uses of acquiring a type object from the column are fixtures (as the YAML file is going to mirror the database more closely than the AR object), and looking up the type during schema detection to pass to the attributes API Many of the failing tests were removed, as they've been made obsolete over the last year. All of the PG column tests were testing nothing beyond polymorphism. The Mysql2 tests were duplicating the mysql tests, since they now share a column class. The implementation is a little hairy, and slightly verbose, but it felt preferable to going back to 20 constructor options for the columns. If you are git blaming to figure out wtf I was thinking with them, and have a better idea, go for it. Just don't use a type object for this.
* Remove most uses of `Column#cast_type`Sean Griffin2015-01-303-9/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal is to remove the type object from the column, and remove columns from the type casting process entirely. The primary motivation for this is clarity. The connection adapter does not have sufficient type information, since the type we want to work with might have been overriden at the class level. By taking this object from the column, it is easy to mistakenly think that the column object which exists on the connection adapter is sufficient. It isn't. A concrete example of this is `serialize`. In 4.2 and earlier, `where` worked in a very inconsistent and confusing manner. If you passed a single value to `where`, it would serialize it before querying, and do the right thing. However, passing it as part of an array, hash, or range would cause it to not work. This is because it would stop using prepared statements, so the type casting would come from arel. Arel would have no choice but to get the column from the connection adapter, which would treat it as any other string column, and query for the wrong value. There are a handful of cases where using the column object to find the cast type is appropriate. These are cases where there is not actually a class involved, such as the migration DSL, or fixtures. For all other cases, the API should be designed as such that the type is provided before we get to the connection adapter. (For an example of this, see the work done to decorate the arel table object with a type caster, or the introduction of `QueryAttribute` to `Relation`). There are times that it is appropriate to use information from the column to change behavior in the connection adapter. These cases are when the primitive used to represent that type before it goes to the database does not sufficiently express what needs to happen. An example of this that affects every adapter is binary vs varchar, where the primitive used for both is a string. In this case it is appropriate to look at the column object to determine which quoting method to use, as this is something schema dependent. An example of something which would not be appropriate is to look at the type and see that it is a datetime, and performing string parsing when given a string instead of a date. This is the type of logic that should live entirely on the type. The value which comes out of the type should be a sufficiently generic primitive that the adapter can be expected to know how to work with it. The one place that is still using the column for type information which should not be necessary is the connection adapter type caster which is sometimes given to the arel table when we can't find the associated table. This will hopefully go away in the near future.
* Don't error when invalid json is assigned to a JSON columnSean Griffin2015-01-211-1/+1
| | | | | | | Keeping with our behavior elsewhere in the system, invalid input is assumed to be `nil`. Fixes #18629.
* Add an `:if_exists` option to `drop_table`Stefan Kanev2015-01-191-1/+1
| | | | | | | | | | | If set to `if_exists: true`, it generates a statement like: DROP TABLE IF EXISTS posts This syntax is supported in the popular SQL servers, that is (at least) SQLite, PostgreSQL, MySQL, Oracle and MS SQL Sever. Closes #16366.
* Time columns should support time zone aware attributesSean Griffin2015-01-151-1/+1
| | | | | | The types that are affected by `time_zone_aware_attributes` (which is on by default) have been made configurable, in case this is a breaking change for existing applications.

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.

| | | | | | | | | | | | | | | | Apparently PG does not validate against RFC 4122. The intent of the original patch is just to protect against PG errors (which potentially breaks txns, etc) because of bad user input, so we shouldn't try any harder than PG itself. Closes #17931

* | Revert to 4.1 behavior for casting PG arraysSean Griffin2014-12-081-0/+3
| | | | | | | | | | | | | | | | | | | | The user is able to pass PG string literals in 4.1, and have it converted to an array. This is also possible in 4.2, but it would remain in string form until saving and reloading, which breaks our `attr = save.reload.attr` contract. I think we should deprecate this in 5.0, and only allow array input from user sources. However, this currently constitutes a breaking change to public API that did not go through a deprecation cycle.
* | Correctly respect subtypes for PG arrays and rangesSean Griffin2014-12-051-7/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | The type registration was simply looking for the OID, and eagerly fetching/constructing the sub type when it was registered. However, numeric types have additional parameters which are extracted from the actual SQL string of the type during lookup, and can have their behavior change based on the result. We simply need to use the block form of registration, and look up the subtype lazily instead. Fixes #17935

| | | | | | | | | | | | The current style for warning messages without newlines uses concatenation of string literals with manual trailing spaces where needed. Heredocs have better readability, and with `squish` we can still produce a single line. This is a similar use case to the one that motivated defining `strip_heredoc`, heredocs are super clean.

| | | | | | | | | | | | While investigating #16951 I found that another library's monkey-patching of `Enumerable` was causing the test migrations helper to break when trying to build the `CREATE DATABASE` statement. The prior approach used `#sum` to build the string from the options hash. As the code that combines the options to build the database statement is not user-facing, using `#inject` here instead will remove the only place where the database creation/migration code is dependent on ActiveSupport's monkey-patching of `Enumerable`.
