* fk: add docsYves Senn2014-06-261-0/+58

* fk: review corrections: indent, visibility, syntax, wording.Yves Senn2014-06-261-8/+9
|
* fk: use random digest namesYves Senn2014-06-261-8/+12
| | | | | | The name of the foreign key is not relevant from a users perspective. Using random names resolves the urge to rename the foreign key when the respective table or column is renamed.
* fk: `add/remove_foreign_key` are noop for adapters that don't support fkYves Senn2014-06-261-0/+4

* fk: infere column name from table names.Yves Senn2014-06-261-4/+14
| | | | This allows to create and remove foreign keys without specifying a column.

| | | | Also improve some of the code conventions
* Fixes bugs for using indexes in CREATE TABLE by adding checks for table ↵Steve Rice2014-03-251-1/+1
| | | | | | | | existence Also: - updates tests by stubbing table_exists? method - adds entry for creating indexes in CREATE TABLE to changelog
* create indexes inline in CREATE TABLE for MySQLCody Cutrer2014-03-251-11/+10
| | | | | | | | This is important, because adding an index on a temporary table after it has been created would commit the transaction Conflicts: activerecord/CHANGELOG.md
* Add missing parantheses in index_exists?Yannick Schutz2014-02-251-1/+1
|
* docs, AR already auto-detects primary keys. Closes #13946. [ci skip]Yves Senn2014-02-051-3/+3
| | | | | This behavior was introduced since Rails 3.1 (207f266ccaaa9cd04cd2a7513ae5598c4358b510) but the docs were still out of date.
* Make change_table use object of current database adapterNishant Modak2014-01-071-5/+5
| | | | | | | | | - Earlier, change_table was creating database-agnostic object. - After this change, it will create correct object based on current database adapter. - This will ensure that create_table and change_table will get same objects. - This makes update_table_definition method public and nodoc. - Fixes #13577 and #13503
* Fix missing closing rdoc tag [ci skip]Carlos Antonio da Silva2013-12-161-1/+1

* support creating temporary tables from queriesCody Cutrer2013-12-141-10/+25
| | | | | also override drop_table in AbstractMySQLAdapter to properly drop temporary tables without committing the transaction
* `connection.type_to_sql` returns a `String` for unmapped types.Yves Senn2013-12-031-1/+1
| | | | | | | | | | Closes #13146. This fixes an error when using: ``` change_colum :table, :column, :bigint, array: true ```
* `rename_index`: add the new index before removing the old one.Yves Senn2013-11-261-2/+2
| | | | | | | | | | | This prevents the following error when a MySQL index on a foreign key column is renamed: ``` ActiveRecord::StatementInvalid: Mysql2::Error: Cannot drop index 'index_engines_on_car_id': needed in a foreign key constraint: DROP INDEX `index_engines_on_car_id` ON `engines` ``` refs: #13038.

| | | | | | | | | | | | | | | | removed two instances of add_column_options! from abstract_mysql_adapter reworked rename_column_sql to remove add_column_options from schema_statements changed to use new hash syntax.
* | Remove behavior that deals with a string as third argument of `add_index`, ↵kennyj2013-06-021-28/+14
| | | | | | | | | | | | because this was deprecated. Some testcases is failed, so I replaced nil to empty hash in add_reference.
* | Merge pull request #10556 from Empact/deprecate-schema-statements-distinctRafael Mendonça França2013-05-121-1/+2
| | | | | | | | | | | | Deprecate SchemaStatements#distinct, and make SchemaStatements#columns_for_distinct nodoc. Conflicts: activerecord/CHANGELOG.md
* | Fix that #exists? can produce invalid SQL: "SELECT DISTINCT DISTINCT"Ben Woosley2013-05-101-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | The combination of a :uniq => true association and the #distinct call in #construct_limited_ids_condition combine to create invalid SQL, because we're explicitly selecting DISTINCT, and also sending #distinct on to AREL, via the relation#distinct_value. Rather than build a select distinct clause in #construct_limited_ids_condition, I set #distinct! and pass just the columns into the select statement. This requires introducing a #columns_for_distinct method to return the select columns but not the statement itself.
* | Refactor index algorithm lookup so that it only builds the available options ↵Carlos Antonio da Silva2013-03-301-4/+4
| | | | | | | | | | | | | | | | | | | | | | once This way the available options are only built for actually fetching the algorithm in case the option is given. The options are going to be necessary a second time only in case the option is given but does not exist, which is supposed to be due to a typo or something like that, so no problem.
