| * Do not use the same name for two `:belongs_to`claudiob2015-02-061-3/+3
| | | | | | | | | | | | | | | | A model cannot have two `:belongs_to` with the same exact name, so we are better off avoiding this code in our examples, which might mislead users in thinking it's admissible. [ci skip]
* | Mention `where.not` in the exampleGodfrey Chan2015-02-141-3/+3
| | | | | | | | | | | | | | ...so it doesn't look like you *have* to use SQL strings for that case (not anymore!). Would like to replace the SQL string example with something that you cannot do with the "normal" query API, but I could not come up with a short, realistic example. Suggestions welcome!

| | | | | | | | | | Using enum names in SQL strings doesn't actually work, the test was wrong (fixed in 3dfd1ba).
* | Enums mapping is a HWIA [ci skip]Godfrey Chan2015-02-131-2/+3
| | | | | | | | | | The previous edit kind of de-emphasized that, so changing it to be more explict. (It also avoids showing it as if it's a string-keyed hash.)
* | Enums should be referred to by symbolsGodfrey Chan2015-02-131-5/+6
| | | | | | | | | | Also updated the documentation about the new ability to query them normally, and added test to make sure they work!
* | Do not overwrite secret token value when already present.Wojciech Wnętrzak2015-02-121-2/+1
| | | | | | | | | | | | | | ``` user = User.create(token: "custom-secure-token") user.token # => "custom-secure-token" ```
* | Optimize none? and one? relation query methods to use LIMIT and COUNT.Eugene Gilburg2015-02-123-2/+30
| | | | | | | | | | | | | | | | Use SQL COUNT and LIMIT 1 queries for none? and one? methods if no block or limit is given, instead of loading the entire collection to memory. The any? and many? methods already follow this behavior. [Eugene Gilburg & Rafael Mendonça França]

| | | | | | | | | | | | | | | | | | | | | | In addition to cleaning up the implementation, this allows type casting behavior to be applied consistently everywhere. (#where for example). A good example of this was the previous need for handling value to key conversion in the setter, because the number had to be passed to `where` directly. This is no longer required, since we can just pass the string along to where. (It's left around for backwards compat) Fixes #18387
* | `current_scope` shouldn't pollute sibling STI classesSean Griffin2015-02-112-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | It looks like the only reason `current_scope` was thread local on `base_class` instead of `self` is to ensure that when we call a named scope created with a proc on the parent class, it correctly uses the default scope of the subclass. The reason this wasn't happening was because the proc captured `self` as the parent class, and we're not actually defining a real method. Using `instance_exec` fixes the problem. Fixes #18806

| | | | | | | | | | | | | | | | | | | | | `quote_default_expression` and `quote_default_value` are almost the same handling for do not quote default function of `:uuid` columns. Rename `quote_default_value` to `quote_default_expression`, and remove duplicate code.
* | | Remove the SQLite3 Binary subclassSean Griffin2015-02-111-18/+0
| | | | | | | | | | | | | | | | | | As far as I can tell, the original reason that this behavior was added has been sufficiently resolved elsewhere, as we no longer remove the encoding of strings coming out of the database.

* | | Remove most PG specific type subclassesSean Griffin2015-02-1113-90/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | The latest version of the PG gem can actually convert the primitives for us in C code, which gives a pretty substantial speed up. A few cases were only there to add the `infinity` method, which I just put on the range type (which is the only place it was used). Floats also needed to parse `Infinity` and `NaN`, but it felt reasonable enough to put that on the generic form.

* | | fix `remove_reference` with `foreign_key: true` on MySQL. #18664.Yves Senn2015-02-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MySQL rejects to remove an index which is used in a foreign key constraint: ``` ActiveRecord::StatementInvalid: Mysql2::Error: Cannot drop index 'index_copies_on_title_id': needed in a foreign key constraint: ALTER TABLE `copies` DROP `title_id` ``` Removing the constraint before removing the column (and the index) solves this problem.

* | | Refactor microsecond precision to be database agnosticSean Griffin2015-02-106-60/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The various databases don't actually need significantly different handling for this behavior, and they can achieve it without knowing about the type of the object. The old implementation was returning a string, which will cause problems such as breaking TZ aware attributes, and making it impossible for the adapters to supply their logic for time objects.

* | rm `Type#number?`Sean Griffin2015-02-073-10/+1
| | | | | | | | | | This predicate is only used in `query_attribute`, and is relatively easy to remove without adding a bunch of is a checks.
* | rm `Type#text?`Sean Griffin2015-02-076-14/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This predicate was only to figure out if it's safe to do case insensitive comparison, which is only a problem on PG. Turns out, PG can just tell us whether we are able to do it or not. If the query turns out to be a problem, let's just replace that method with checking the SQL type for `text` or `character`. I'd rather not burden the type objects with adapter specific knowledge. The *real* solution, is to deprecate this behavior entirely. The only reason we need it is because the `:case_sensitive` option for `validates_uniqueness_of` is documented as "this option is ignored for non-strings". It makes no sense for us to do that. If the type can't be compared in a case insensitive way, the user shouldn't tell us to do case insensitive comparison.
* | Move non-type objects into the `Type::Helpers` namespaceSean Griffin2015-02-0719-104/+110
| | | | | | | | | | | | | | 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.
* | rm `ActiveRecord::Type::Decorator`Sean Griffin2015-02-074-28/+0
| | | | | | | | | | | | | | It only existed to make sure the subclasses of `Delegator` were YAML serializable. As of Ruby 2.2, these are YAML dumpable by default, as it includes https://github.com/tenderlove/psych/commit/2a4d9568f7d5d19c00231cf48eb855cc45ec3394
* | Push multi-parameter assignement into the typesSean Griffin2015-02-0711-108/+69
| | | | | | | | | | | | | | | | | | | | | | | | This allows us to remove `Type::Value#klass`, as it was only used for multi-parameter assignment to reach into the types internals. The relevant type objects now accept a hash in addition to their previous accepted arguments to `type_cast_from_user`. This required minor modifications to the tests, since previously they were relying on the fact that mulit-parameter assignement was reaching into the internals of time zone aware attributes. In reaility, changing those properties at runtime wouldn't change the accessor methods for all other forms of assignment.
