* Reworked ActiveRecord::Relation#last to always use SQLBogdan Gusiev2016-01-281-0/+20
| | | | instead of loading relation
* Introduce ActiveRecord::IrreversibleOrderErrorBogdan Gusiev2016-01-271-0/+14
| | | | | Raises when #reverse_order can not process SQL order instead of making invalid SQL before this patch
* INSERT INTO schema_migrations in 1 SQLAkira Matsuda & Naoto Koshikawa2016-01-271-0/+5
| | | | | | | 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
* Pare back default `index` option for the migration generatorPrathamesh Sonpatki2016-01-241-0/+9
| | | | | | | | | | - Using `references` or `belongs_to` in migrations will always add index for the referenced column by default, without adding `index:true` option to generated migration file. - Users can opt out of this by passing `index: false`. - Legacy migrations won't be affected by this change. They will continue to run as they were before. - Fixes #18146

|/ | | | | | | | | | | | | glittershark/if-and-unless-in-secure-token" This reverts commit 224eddfc0eeff6555ae88691306e61c7a9e8b758, reversing changes made to 9d681fc74c6251d5f2b93fa9576c9b2113116680. When merging the pull request, I misunderstood `has_secure_token` as declaring a model has a token from birth and through the rest of its lifetime. Therefore, supporting conditional creation doesn't make sense. You should never mark a model as having a secure token if there's a time when it shouldn't have it on creation.

|\ | | | | | | Add short-hand methods for text and blob types in MySQL
| * Add short-hand methods for text and blob types in MySQLRyuta Kamizono2016-01-051-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Pg and Sqlite3, `:text` and `:binary` have variable unlimited length. But in MySQL, these have limited length for each types (ref #21591, #21619). This change adds short-hand methods for each text and blob types. Example: create_table :foos do |t| t.tinyblob :tiny_blob t.mediumblob :medium_blob t.longblob :long_blob t.tinytext :tiny_text t.mediumtext :medium_text t.longtext :long_text end
* | Move CHANGELOG entry to Active RecordRafael Mendonça França2016-01-051-0/+5
|/ | | | | | | | While the type definition is in Active Model the change of behavior will be only user facing in Active Record so better to put the entry in its changelog. [ci skip]
* Fix `first(limit)` to take advantage of `loaded?` records if availableBen Woosley2015-12-241-0/+5
| | | | | | | | | | | | | | | | | I realized that `first(2)`, etc. was unnecessarily querying for the records when they were already preloaded. This was because `find_nth_with_limit` can not know which `@records` to return because it conflates the `offset` and `index` into a single variable, while the `@records` only needs the `index` itself to select the proper record. Because `find_nth` and `find_nth_with_limit` are public methods, I instead introduced a private method `find_nth_with_limit_and_offset` which is called internally and handles the `loaded?` checking. Once the `offset` argument is removed from `find_nth`, `find_nth_with_limit_and_offset` can be collapsed into `find_nth_with_limit`, with `offset` always equal to `offset_index`.
* Deprecate passing `offset` to `find_nth`Ben Woosley2015-12-241-0/+5
| | | | | | | | All uses of the `offset` are passing `offset_index`. Better to push down the `offset` consideration into `find_nth`. This also works toward enabling `find_nth_with_limit` to take advantage of the `loaded?` state of the relation.

| | | | | | | | | | | | | | | | | | methyl/fix-includes-for-groupped-association" This reverts commit 537ac7d6ade61e95f2b70685ff2236b7de965bab, reversing changes made to 9c9c54abe08d86967efd3dcac1d65158a0ff74ea. Reason: The way we preload associations will change the meaning of GROUP BY operations. This is illustrated in the SQL generated by the added test (failing on PG): Association Load: D, [2015-12-21T12:26:07.169920 #26969] DEBUG -- : Post Load (0.7ms) SELECT "posts".* FROM "posts" LEFT JOIN comments ON comments.post_id = posts.id WHERE "posts"."author_id" = $1 GROUP BY posts.id ORDER BY SUM(comments.tags_count) [["author_id", 1]] Preload: D, [2015-12-21T12:26:07.128305 #26969] DEBUG -- : Post Load (1.3ms) SELECT "posts".* FROM "posts" LEFT JOIN comments ON comments.post_id = posts.id WHERE "posts"."author_id" IN (1, 2, 3) GROUP BY posts.id ORDER BY SUM(comments.tags_count)

* | | | Introduce ApplicationRecord, an Active Record layer supertypeGenadi Samokovarov2015-12-161-0/+15
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's pretty common for folks to monkey patch `ActiveRecord::Base` to work around an issue or introduce extra functionality. Instead of shoving even more stuff in `ActiveRecord::Base`, `ApplicationRecord` can hold all those custom work the apps may need. Now, we don't wanna encourage all of the application models to inherit from `ActiveRecord::Base`, but we can encourage all the models that do, to inherit from `ApplicationRecord`. Newly generated applications have `app/models/application_record.rb` present by default. The model generators are smart enough to recognize that newly generated models have to inherit from `ApplicationRecord`, but only if it's present.

* | | Use a bind param for `LIMIT` and `OFFSET`Sean Griffin2015-12-141-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently generate an unbounded number of prepared statements when `limit` or `offset` are called with a dynamic argument. This changes `LIMIT` and `OFFSET` to use bind params, eliminating the problem. `Type::Value#hash` needed to be implemented, as it turns out we busted the query cache if the type object used wasn't exactly the same object. This drops support for passing an `Arel::Nodes::SqlLiteral` to `limit`. Doing this relied on AR internals, and was never officially supported usage. Fixes #22250.

A: An `ActiveModel::ForbiddenAttributesError` is raised. I think this behavior is correct, and it's better than what used to happen, with unpermitted parameter being simply ignored.

This is due to the changes made in https://github.com/rails/rails/pull/17885 The problem is that multiple schemas were getting getting passed to `Kernel.system` as a single, space delimited string argument (for example, "--schema=foo --schema=bar"). However, with the updated array style of calling `Kernel.system`, these need to be passed as separate arguments (for example, "--schema=foo", "--schema=bar"). If they get passed as a single string, then the underlying pg_dump program isn't sure how to interpret that single argument and you'll get an error reporting: "pg_dump: No matching schemas were found"

| | | | | | | | | | | | | | | | | | | | | This reverts commit 8246b593bff71f2cebf274c133bb8917f1e094c8. There was concern about this modifying the behavior of past migrations. We're going to add an way to modify the migration generator instead.
* | | Allow specifying the default table options for mysql adaptersSean Griffin2015-11-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's often the case that you want to have an option that you cannot specify at the database level, but want applied to *all* tables that you create. For example, you might want to specify `ROW_FORMAT=DYNAMIC` to not have to limit text columns to length 171 for indexing when using utf8mb4. This allows an easy way to specify this in your database configuration. While this change affects both MySQL and MySQL2, the test only covers MySQL2, as the legacy mysql adapter appears to always return ASCII strings, and is tangential to what we're actually doing.
