| * | | Remove unnecessary display widthRyuta Kamizono2015-09-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The **(11)** does not affect the storage size of the data type, which for an INT will always be 4 bytes. It affects the **display width**. http://www.tocker.ca/2015/07/02/proposal-to-deprecate-mysql-integer-display-width-and-zerofill.html

* | Add reversible syntax for change_column_defaultPrem Sichanugrist2015-06-261-1/+14
|/ | | | | | | | | | | | | Passing `:from` and `:to` to `change_column_default` makes this command reversible as user has defined its previous state. So, instead of having the migration command as: change_column_default(:posts, :state, "draft") They can write it as: change_column_default(:posts, :state, from: nil, to: "draft")
* make `remove_index :table, :column` reversible.Yves Senn2015-06-151-1/+1
| | | | | | | | | This used to raise a `IrreversibleMigration` error (since #10437). However since `remove_index :table, :column` is probably the most basic use-case we should make it reversible again. Conflicts: activerecord/CHANGELOG.md

| | | | | | | | | | | | | | | | | | | | 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 a common class to reduce the duplication for `references`Sean Griffin2014-12-231-30/+2
| | | | | | | | The code for `TableDefinition#references` and `SchemaStatements#add_reference` were almost identical both structurally, and in terms of domain knowledge. This removes that duplication into a common class, using the `Table` API as the expected interface of its collaborator.
* Add `foreign_key` as an option to `references` for `change_table`Sean Griffin2014-12-221-1/+16
| | | | | | | | | | | This has the same comments as 9af90ffa00ba35bdee888e3e1ab775ba0bdbe72c, however it affects the `add_reference` method, and `t.references` in the context of a `change_table` block. There is a lot of duplication of code between creating and updating tables. We should re-evaluate the structure of this code from a high level so changes like this don't need to be made in two places. (Note to self)
* Convert `add_references` to use kwargsSean Griffin2014-12-221-6/+18
| | | | | | While we still aren't accepting PRs that only make changes like this, it's fine when we're actively working on a method if it makes our lives easier.
* Add a `foreign_key` option to `references` while creating the tableSean Griffin2014-12-221-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than having to do: create_table :posts do |t| t.references :user end add_foreign_key :posts, :users You can instead do: create_table :posts do |t| t.references :user, foreign_key: true end Similar to the `index` option, you can also pass a hash. This will be passed as the options to `add_foreign_key`. e.g.: create_table :posts do |t| t.references :user, foreign_key: { primary_key: :other_id } end is equivalent to create_table :posts do |t| t.references :user end add_foreign_key :posts, :users, primary_key: :other_id
