| | | | | | | | | | | | The current documentation explicitly mentions only PostgreSQL (hstore/json) for use with `.store_accessor`, making it somewhat confusing what to choose on a MySQL 5.7+ setup (which introduced a json data type).

|\ \ | | | | | | Fix default connection handling with three-tier config
| * | Fix connection handling with three-tier configeileencodes2018-03-162-1/+4
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you had a three-tier config, the `establish_connection` that's called in the Railtie on load can't figure out how to access the default configuration. This is because Rails assumes that the config is the first value in the hash and always associated with the key from the environment. With a three tier config however we need to go one level deeper. This commit includes 2 changes. 1) removes a line from `resolve_all` which was parsing out the the environment from the config so instead of getting ``` { :development => { :primary => { :database => "whatever" } }, :animals => { :database => "whatever-animals" } }, etc with test / prod } ``` We'd instead end up with a config that had no attachment to it's envioronment. ``` { :primary => { :database => "whatever" } :animals => { :database => "whatever-animals" } etc - without test and prod } ``` Not only did this mean that Active Record didn't know how to establish a connection, it didn't have the other necessary configs along with it in the configs list. So fix this I removed the line that deletes these configs. The second thing this commit changes is adding this line to `establish_connection` ``` spec = spec[spec_name.to_sym] if spec[spec_name.to_sym] ``` When you have a three-tier config and don't pass any hash/symbol/env etc to `establish_connection` the resolver will automatically return both the primary and secondary (in this case animals db) configurations. We'll get an `database configuration does not specify adapter` error because AR will try to establish a connection on the `primary` key rather than the `primary` key's config. It assumes that the `development` or default env automatically will return a config hash, but with a three-tier config we actually get a key and config `primary => config`. This fix is a bit of a bandaid because it's not the "correct" way to handle this situation, but it does solve our immediate problem. The new code here is saying "if the config returned from the resolver (I know it's called spec in here but we interchange our meanings a LOT and what is returned is a three-tier config) has a key matching the "primary" spec name, grab the config from the spec and pass that to the estalbish_connection method". This works because if we pass `:animals` or a hash, or `:primary` we'll already have the correct configuration to connect with. This fixes the case where we want Rail to connect with the default connection. Coming soon is a refactoring that should eliminate the need to do this but I need this fix in order to write the multi-db rake tasks that I promised in my RailsConf submission. `@tenderlove` and I are working on the refactoring of the internals for connection management but it won't be ready for a few weeks and this issue has been blocking progress.

* | | Ensure that leading date is stripped by quoted_timeAndrew White2018-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | In #24542, quoted_time was introduced to strip the leading date component for time columns because it was having a significant effect in mariadb. However, it assumed that the date component was always 2000-01-01 which isn't the case, especially if the source wasn't another time column.
* | | Normalize date component when writing to time columnsAndrew White2018-03-111-1/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | For legacy reasons Rails stores time columns on sqlite as full timestamp strings. However because the date component wasn't being normalized this meant that when they were read back they were being prefixed with 2001-01-01 by ActiveModel::Type::Time. This had a twofold result - first it meant that the fast code path wasn't being used because the string was invalid and second it was corrupting the second fractional component being read by the Date._parse code path. Fix this by a combination of normalizing the timestamps on writing and also changing Active Model to be more lenient when detecting whether a string starts with a date component before creating the dummy time value for parsing.

| | | | | | | | | | | | | | | | | | locking is enabled This issue is caused by `@_trigger_update_callback` won't be updated due to `_update_record` in `Locking::Optimistic` doesn't call `super` when optimistic locking is enabled. Now optimistic locking concern when updating is supported by `_update_row` low level API, therefore overriding `_update_record` is no longer necessary. Removing the method just fix the issue. Closes #29096. Closes #29321. Closes #30823.

* `id_in_database` should be respected as primary key value for persisted recordsRyuta Kamizono2018-03-052-2/+2
| | | | | | | | | | | | Currently primary key value can not be updated if a record has a locking column because of `_update_record` in `Locking::Optimistic` doesn't respect `id_in_database` as primary key value unlike in `Persistence`. And also, if a record has dirty primary key value, it may destroy any other record by the lock version of dirty record itself. When updating/destroying persisted records, it should identify themselves by `id_in_database`, not by dirty primary key value.
* `id_in_database` do not return nil value for persisted recordRyuta Kamizono2018-03-042-4/+4

* Eager loading with polymorphic associations should behave consistentlyRyuta Kamizono2018-03-042-7/+5
| | | | | | | | | | This reverts ignoring polymorphic error introduced at 02da8ae. What the ignoring want to solve was caused by force eager loading regardless of whether it is necessary, but it has been fixed by #29043. The ignoring is now only causing a mismatch of `exists?` behavior with `to_a`, `count`, etc. It should behave consistently.

| | | | | | | | | | | | | | | | | | | | | | | | The previous documentation is somewhat unclear about the use case for an abstract ActiveRecord class. This clears it up by highlighting the following points: - table_name is not derived from the abstract class' name - type is not derived on direct descendants of the abstract class - validations, not abstract_class, should be used to specify whether the parent model can be instantiated or not

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Actually `reflection.klass` should be valid AR model unless `polymorphic?`. Previously it worked limitedly by ignoring `NameError` even if `reflection.klass` is invalid, and our isolated testing depends on the limited working. Probably we should also check the klass validity in `check_validity!` properly. Until that time, I restored the error suppression for now. Closes #32113.

| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the place where we limit what gets sent to the database is in the implementation for `partial_writes`. We should also be restricting it to column names when partial writes are turned off. Note that we're using `&` instead of just defaulting to `self.class.column_names`, as the instance version of `attribute_names` does not include attributes which are uninitialized (were not included in the select clause)
