* 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.
* Refactor `visit_ChangeColumnDefinition`Ryuta Kamizono2015-01-031-10/+8
| | | | `visit_ChangeColumnDefinition` is the same "CHANGE column_name " + `visit_ColumnDefinition(o)`.
* Add default value for `create_table_definition`Ryuta Kamizono2015-01-031-2/+2
| | | | | In most cases, `create_table_definition` called by table_name (the first argument) only.

In 5.5, when you insert `2014-08-17 12:30:00.999999` the fractional part is ignored. In 5.6, it's rounded to `2014-08-17 12:30:01`: http://bugs.mysql.com/bug.php?id=68760

* Revert the behavior of booleans in string columns to that of 4.1Sean Griffin2014-11-091-1/+23
| | | | | | | | | | | | | | | | | | | | | Why are people assigning booleans to string columns? >_> We unintentionally changed the behavior on Sqlite3 and PostgreSQL. Boolean values should cast to the database's representation of true and false. This is 't' and 'f' by default, and "1" and "0" on Mysql. The implementation to make the connection adapter specific behavior is hacky at best, and should be re-visted once we decide how we actually want to separate the concerns related to things that should change based on the database adapter. That said, this isn't something I'd expect to change based on my database adapter. We're storing a string, so the way the database represents a boolean should be irrelevant. It also seems strange for us to give booleans special behavior at all in string columns. Why is `to_s` not sufficient? It's inconsistent and confusing. Perhaps we should consider deprecating in the future. Fixes #17571

* | fix MySQL enum type lookup with values matching another type. Closes #17402.Yves Senn2014-10-291-6/+6
| | | | | | | | | | | | | | | | | | | | The MySQLAdapter type map used the lowest priority for enum types. This was the result of a recent refactoring and lead to some broken lookups for enums with values that match other types. Like `8bit`. This patch restores the priority to what we had before the refactoring. /cc @sgrif

* MySQL: set connection collation along with the charsetJeremy Kemper2014-08-301-1/+5
| | | | | | | | | | Sets the connection collation to the database collation configured in database.yml. Otherwise, `SET NAMES utf8mb4` will use the default collation for that charset (utf8mb4_general_ci) when you may have chosen a different collation, like utf8mb4_unicode_ci. This only applies to literal string comparisons, not column values, so it is unlikely to affect you.
* Change the default `null` value for timestampsSean Griffin2014-08-121-2/+2
| | | | | | | As per discussion, this changes the model generators to specify `null: false` for timestamp columns. A warning is now emitted if `timestamps` is called without a `null` option specified, so we can safely change the behavior when no option is specified in Rails 5.

* If our connection is explicitly non-strict, tell MySQLMatthew Draper2014-07-061-2/+2
| | | | | | | | | | We default to making the connection strict, but have historically relied on the MySQL default when we want it to be non-strict. On some (recent?) versions of MySQL, new connections default to being strict, so if we've been told 'strict:false', we're obliged to pass that on. This fixes a test failure that we've seen turn up on relatively-new development machines, so we do already have a test covering it.

* Don't type cast the default on the columnSean Griffin2014-06-171-7/+6
| | | | | | | If we want to have type decorators mess with the attribute, but not the column, we need to stop type casting on the column. Where possible, we changed the tests to test the value of `column_defaults`, which is public API. `Column#default` is not.

* Don't query the database schema when calling `serialize`Sean Griffin2014-06-071-8/+11
| | | | | | We need to decorate the types lazily. This is extracted to a separate API, as there are other refactorings that will be able to make use of it, and to allow unit testing the finer points more granularly.
