* Avoid extra `show variables` in migrationRyuta Kamizono2016-02-011-1/+5
| | | | | | | | | | | | | `initialize_schema_migrations_table` is called in every migrations. https://github.com/rails/rails/blob/v5.0.0.beta1/activerecord/lib/active_record/migration.rb#L1080 https://github.com/rails/rails/blob/v5.0.0.beta1/activerecord/lib/active_record/schema.rb#L51 This means that extra `show variables` is called regardless of the existence of `schema_migrations` table. This change is to avoid extra `show variables` if `schema_migrations` table exists.

| * Warn if `AR.primary_key` is called for a table who has composite primary keyyui-knk2016-01-301-0/+6
| | | | | | | | | | | | | | | | If `AR.primary_key` is called for a table who has composite primary key, the method returns `nil`. This behavior sometimes generates invalid SQL. The first time developers notice to invalid SQL is when they execute SQL. This commit enables developers to know they are doing something dangerous as soon as possible.

* INSERT INTO schema_migrations in 1 SQLAkira Matsuda & Naoto Koshikawa2016-01-271-10/+8
| | | | | | | We found that inserting all 600 schema_migrations for our mid-sized app takes about a minute on a cloud based CI environment. I assume that the original code did not use multi-row-insert because SQLite3 was not supporting the syntax back then, but it's been supported since 3.7.11: http://www.sqlite.org/releaselog/3_7_11.html

| * Prevent destructive action on production databaseschneems2016-01-071-0/+4
| | | | | | | | | | | | | | This PR introduces a key/value type store to Active Record that can be used for storing internal values. It is an alternative implementation to #21237 cc @sgrif @matthewd. It is possible to run your tests against your production database by accident right now. While infrequently, but as an anecdotal data point, Heroku receives a non-trivial number of requests for a database restore due to this happening. In these cases the loss can be large. To prevent against running tests against production we can store the "environment" version that was used when migrating the database in a new internal table. Before executing tests we can see if the database is a listed in `protected_environments` and abort. There is a manual escape valve to force this check from happening with environment variable `DISABLE_DATABASE_ENVIRONMENT_CHECK=1`.
* | Add `columns_for_distinct` for MySQL 5.7 with ONLY_FULL_GROUP_BYRyuta Kamizono2015-12-231-2/+3
| | | | | | | | | | | | | | | | | | In MySQL 5.7.5 and up, ONLY_FULL_GROUP_BY affects handling of queries that use DISTINCT and ORDER BY. It requires the ORDER BY columns in the select list for distinct queries, and requires that the ORDER BY include the distinct column. See https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html

|/ | | | | | | | | | Reported on #21509, how views is treated by `#tables` are differ by each adapters. To fix this different behavior, after Rails 5.0 is released, deprecate `#tables`. And `#table_exists?` would check both tables and views. To make their behavior consistent with `#tables`, after Rails 5.0 is released, deprecate `#table_exists?`.
* move documentation of column options to `add_column`. Closes #20400.Yves Senn2015-10-211-6/+75
| | | | | | | | | | | | [ci skip] It's been a source of confusion that the lower-level `add_column` referenced the higher level `column` method for available options. `column` supports additional functionality like `index: true` that is not present on `add_column`. This patch moves common option documentation to `add_column` and only documents the additional options in `column`.
* applies new doc guidelines to Active Record.Yves Senn2015-10-141-10/+11
| | | | | | | | | | | | | | | | | | | The focus of this change is to make the API more accessible. References to method and classes should be linked to make it easy to navigate around. This patch makes exzessiv use of `rdoc-ref:` to provide more readable docs. This makes it possible to document `ActiveRecord::Base#save` even though the method is within a separate module `ActiveRecord::Persistence`. The goal here is to bring the API closer to the actual code that you would write. This commit only deals with Active Record. The other gems will be updated accordingly but in different commits. The pass through Active Record is not completely finished yet. A follow up commit will change the spots I haven't yet had the time to update. /cc @fxn
* `:to_table` when adding a fk through `add_reference`.Yves Senn2015-10-131-0/+4
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
