| * Fix ActiveRecord::Relation#cache_key for relations with no resultsPrathamesh Sonpatki2016-01-221-0/+5
| | | | | | | | | | | | | | - When relations return no result or 0 result then cache_key should handle it gracefully instead of blowing up trying to access `result[:size]` and `result[:timestamp]`. - Fixes #23063.
* | Pare back default `index` option for the migration generatorPrathamesh Sonpatki2016-01-244-11/+29
| | | | | | | | | | | | | | | | | | | | - 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
* | Use the database type to deserialize enumSean Griffin2016-01-231-0/+10
|/ | | | | | | | | | | | This fixes incorrect assumptions made by e991c7b that we can assume the DB is already casting the value for us. The enum type needs additional information to perform casting, and needs a subtype. I've opted not to call `super` in `cast`, as we have a known set of types which we accept there, and the subtype likely doesn't accept them (symbol -> integer doesn't make sense) Close #23190

| * Fix ActiveRecord::Relation#cache_key for loaded empty collectionPrathamesh Sonpatki2016-01-161-0/+8
| | | | | | | | | | | | | | | | | | - Before this patch if we try to find cache_key of a loaded but empty collection it used to give error because of trying to call `updated_at` on `nil` value generated by `collection.max_by(&timestamp_column).public_send(timestamp_column)`. - This commit fixes above error by checking if size is greater than zero or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | This PR addresses the issue described in https://github.com/rails/rails/pull/22967#issuecomment-170251635. If the database is non empty and has no new migrations than `db:migrate` will not set the environment. This PR works by always setting the environment value on successful `up` migration regardless of whether or not a migration was actually executed.

* | Revert "Change `WhereClause#merge` to same named columns on diff tables"Sean Griffin2016-01-121-15/+2
| | | | | | | | | | | | | | | | | | This reverts commit 5d41cb3bfd6b19833261622ce5d339b1e580bd8b. This implementation does not properly handle cases involving predicates which are not associated with a bind param. I have the fix in mind, but don't have time to implement just yet. It will be more similar to #22823 than not.
* | Change `WhereClause#merge` to same named columns on diff tablesSean Griffin2016-01-121-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the predicates are an arel equality node where the left side is a full arel attribute, the binds just have the name of the column and nothing else. This means that while splitting the predicates can include the table as a factor, the binds cannot. It's entirely possible that we might be able to have the bind params carry a bit more information (I don't believe the name is used for anything but logging), and that is probably a worthwhile change to make in the future. However the simplest (and likely slightly faster) solution is to simply use the indices of the conflicts in both cases. This means that we only have to compute the collision space once, instead of twice even though we're doing an additional array iteration. Regardless, this method isn't a performance hotspot. Close #22823. [Ben Woosley & Sean Griffin]
* | Skip the STI condition when evaluating a default scopeMatthew Draper2016-01-121-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | Given a default_scope on a parent of the current class, where that parent is not the base class, the parent's STI condition would become attached to the evaluated default scope, and then override the child's own STI condition. Instead, we can treat the STI condition as though it is a default scope, and skip it in this situation: the scope will be merged into the base relation, which already contains the correct STI condition. Fixes #22426.
* | Active scopes apply to child classes, though not parents/siblingsMatthew Draper2016-01-122-5/+20
|/ | | | | | | While the commit message (and changelog example) in 5e0b555b453ea2ca36986c111512627d806101e7 talked about sibling classes, the added test had a child ignore its parent's scoping, which seems less reasonable.

| * Get update_attributes working with SchemaMigrationschneems2016-01-081-2/+2
| | | | | | | | You cannot use `update_attributes` on models that do not have a primary key. Since SchemaMigration versions are guaranteed to be unique (they have a unique index on them) we can safely use them as a primary key.
* | Refactor tz aware types, add support for PG rangesSean Griffin2016-01-081-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an alternate implementation to #22875, that generalizes a lot of the logic that type decorators are going to need, in order to have them work with arrays, ranges, etc. The types have the ability to map over a value, with the default implementation being to just yield that given value. Array and Range give more appropriate definitions. This does not automatically make ranges time zone aware, as they need to be added to the `time_zone_aware` types config, but we could certainly make that change if we feel it is appropriate. I do think this would be a breaking change however, and should at least have a deprecation cycle. Closes #22875. /cc @matthewd

| * Prevent destructive action on production databaseschneems2016-01-073-0/+76
| | | | | | | | | | | | | | 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`.
