* introduce `conn.data_source_exists?` and `conn.data_sources`.Yves Senn2015-09-221-1/+1
| | | | | | | | | | | | | | | | | 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)
* Merge pull request #21609 from kamipo/do_not_dump_view_as_tableJeremy Daer2015-09-191-1/+1

| * Do not dump a view as a table in sqlite3, mysql and mysql2 adaptersRyuta Kamizono2015-09-131-1/+1
| | | | | | | | | | | | Now in sqlite3, mysql and mysql2 adapters, SchemaDumper dump a view as a table. It is incorrect behavior. This change excludes a view in schema.rb.
* | Correctly dump composite primary keyRyuta Kamizono2015-09-201-6/+13

* | Don't hardcode table nameschneems2015-09-161-1/+1
|/ | | | | The schema_migrations table name is configurable. We should use this value when checking for ignored table names when dumping schema instead of a hardcoded value.

| | | | | | | | | | If the adapter supports indexes in create table, generated SQL is slightly more efficient.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gems which wish to tie into ActiveRecord::SchemaDumper need to duplicate this logic currently. [Foreigner] is one such example, as is a library I'm currently working on but which hasn't been released yet: def tables_with_foreign_keys(stream) tables_without_foreign_keys(stream) @connection.tables.sort.each do |table| next if ['schema_migrations', ignore_tables].flatten.any? do |ignored| case ignored when String; table == ignored when Regexp; table =~ ignored else raise StandardError, 'ActiveRecord::SchemaDumper.ignore_tables accepts an array of String and / or Regexp values.' end end foreign_keys(table, stream) end end [Foreigner]: https://github.com/matthuhiggins/foreigner/blob/master/lib/foreigner/schema_dumper.rb#L36-L43 Extract the skip logic to a method, making it much simpler to follow this same behavior in gems that are tying into the migration flow and let them dump only tables that aren't skipped without copying this block of code. The above code could then be simplified to: def tables_with_foreign_keys(stream) tables_without_foreign_keys(stream) @connection.tables.sort.each do |table| foreign_keys(table, stream) unless ignored?(table) end end It also, in my opinion, simplifies the logic on ActiveRecord's side, and clarifies the intent of the skip logic.
* Dump PostgreSQL primary key with custom function as a default.Andrey Novikov2014-07-111-1/+2
| | | | | | | | | | | For example, if use pgcrypto extension in PostgreSQL 9.4 beta 1, where uuid-ossp extension isn't available for moment of writing, and thus to use a gen_random_uuid() method as a primary key default. In this case schema dumper wasn't able to correctly reconstruct create_table statement and lost primary key constraint on schema load. Fixes #16111.
* fk: use random digest namesYves Senn2014-06-261-3/+13
| | | | | | 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.

* Moves column dump specific code to a module included in AbstractAdapterDan McClain2012-09-141-29/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having column related schema dumper code in the AbstractAdapter. The code remains the same, but by placing it in the AbstractAdapter, we can then overwrite it with Adapter specific methods that will help with Adapter specific data types. The goal of moving this code here is to create a new migration key for PostgreSQL's array type. Since any datatype can be an array, the goal is to have ':array => true' as a migration option, turning the datatype into an array. I've implemented this in postgres_ext, the syntax is shown here: https://github.com/dockyard/postgres_ext#arrays Adds array migration support Adds array_test.rb outlining the test cases for array data type Adds pg_array_parser to Gemfile for testing Adds pg_array_parser to postgresql_adapter (unused in this commit) Adds schema dump support for arrays Adds postgres array type casting support Updates changelog, adds note for inet and cidr support, which I forgot to add before Removing debugger, Adds pg_array_parser to JRuby platform Removes pg_array_parser requirement, creates ArrayParser module used by PostgreSQLAdapter
