* `:to_table` when adding a fk through `add_reference`.Yves Senn2015-10-132-3/+13
| | | | | | | | | | | | Closes #21563. The `name` argument of `add_references` was both used to generate the column name `<name>_id` and as the target table for the foreign key `name.pluralize`. It's primary purpose is to define the column name. In cases where the `to_table` of the foreign key is different than the column name we should be able to specify it individually.
* Move the methods for schema dumping into `{mysql,postgresql}/schema_dumper.rb`Ryuta Kamizono2015-10-131-1/+1
| | | | | Current master branch includes many schema dumping improvements. It extract these features to the appropriate files.

* | introduce `conn.data_source_exists?` and `conn.data_sources`.Yves Senn2015-09-221-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These new methods are used from the Active Record model layer to determine which relations are viable to back a model. These new methods allow us to change `conn.tables` in the future to only return tables and no views. Same for `conn.table_exists?`. The goal is to provide the following introspection methods on the connection: * `tables` * `table_exists?` * `views` * `view_exists?` * `data_sources` (views + tables) * `data_source_exists?` (views + tables)

| | | | | | | | | | | | | | | | | | | | | | | | Previously there was no separator between the two code examples so it looked like: ```ruby CREATE INDEX by_name ON accounts(name(10)) add_index(:accounts, [:name, :surname], name: 'by_name_surname', length: {name: 10, surname: 15}) ```
* | | Support for foreign keys in create tableRyuta Kamizono2015-09-202-17/+25
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If foreign keys specified in create table, generated SQL is slightly more efficient. Definition: ``` create_table :testings do |t| t.references :testing_parent, foreign_key: true end ``` Before: ``` CREATE TABLE "testings" ("id" serial primary key, "testing_parent_id" integer); ALTER TABLE "testings" ADD CONSTRAINT "fk_rails_a196c353b2" FOREIGN KEY ("testing_parent_id") REFERENCES "testing_parents" ("id"); ``` After: ``` CREATE TABLE "testings" ("id" serial primary key, "testing_parent_id" integer, CONSTRAINT "fk_rails_a196c353b2" FOREIGN KEY ("testing_parent_id") REFERENCES "testing_parents" ("id")); ```

|/ | | | | | | | | | | | | 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")

| * Add schema cache to new connection pool after forkEugene Kenny2015-05-171-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Active Record detects when the process has forked and automatically creates a new connection pool to avoid sharing file descriptors. If the existing connection pool had a schema cache associated with it, the new pool should copy it to avoid unnecessarily querying the database for its schema. The code to detect that the process has forked is in ConnectionHandler, but the existing test for it was in the ConnectionManagement test file. I moved it to the right place while I was writing the new test for this change.
