Ryuta Kamizono	da5843436b	SQLite3: Implement add_foreign_key and remove_foreign_key ... I implemented Foreign key create in `create_table` for SQLite3 at #24743. This follows #24743 to implement `add_foreign_key` and `remove_foreign_key`. Unfortunately SQLite3 has one limitation that `PRAGMA foreign_key_list(table-name)` doesn't have constraint name. So we couldn't implement find/remove foreign key by name for now. Fixes #35207. Closes #31343.	2019-02-11 14:15:16 +09:00
Ryuta Kamizono	1745e905a3	Allow changing text and blob size without giving the limit option ... In MySQL, the text column size is 65,535 bytes by default (1 GiB in PostgreSQL). It is sometimes too short when people want to use a text column, so they sometimes change the text size to mediumtext (16 MiB) or longtext (4 GiB) by giving the `limit` option. Unlike MySQL, PostgreSQL doesn't allow the `limit` option for a text column (raises ERROR: type modifier is not allowed for type "text"). So `limit: 4294967295` (longtext) couldn't be used in Action Text. I've allowed changing text and blob size without giving the `limit` option, it prevents that migration failure on PostgreSQL.	2019-01-29 06:49:32 +09:00

Ryuta Kamizono	db077e8090	Allow using Action Mailbox on MySQL 5.5 ... Active Record still support MySQL 5.5 which doesn't support datetime with precision. 9e34df0003/activerecord/lib/active_record/connection_adapters/abstract_mysql_adapter.rb (L99-L101) So we should check `supports_datetime_with_precision?` on the connection.	2019-01-18 07:04:08 +09:00
