* Properly create through records when called with `where`Sean Griffin2015-02-261-0/+7
| | | | | | | | | | | Various behaviors needed by associations (such as creating the through record) are lost when `where` is called, since we stop having a `CollectionProxy` and start having an `AssociationRelation` which does not contain this behavior. I *think* we should be able to rm `AssociationRelation`, but we have tests saying the changes required to do that would be bad (Without saying why. Of course. >_>) Fixes #19073.

* rework `disable_referential_integrity` for PostgreSQL.Yves Senn2015-02-241-0/+19
| | | | | | | | | | | | | | | | | | | | | | | [Toby Ovod-Everett & Andrey Nering & Yves Senn] Closes #17726. Closes #10939. This patch makes three distinct modifications: 1. no longer fall back to disabling user triggers if system triggers can't be disabled 2. warn the user when referential integrity can't be disabled 3. restore aborted transactions when referential integrity can't be disabled The motivation behind these changes is to make the behavior of Rails transparent and less error-prone. To require superuser privileges is not optimal but it's what Rails currently needs. Users who absolutely rely on disabling user triggers can patch `disable_referential_integrity`. We should investigate `SET CONSTRAINTS` as a possible solution which does not require superuser privileges. /cc @matthewd

| * Always reset changed attributes in becomesMiklos Fazekas2015-02-041-0/+6
| | | | | | | | | | | | | | | | | | | | When ```becomes``` changes @attributes it should also change @changed_attributes. Otherwise we'll experience a kind of split head situation where attributes are coming from ```self```, but changed_attributes is coming from ```klass.new```. This affects the inheritance_colmn as it's changed by new for example. Fixes #16881

* | Add `time` option to `#touch`Hyonjee Joo2015-02-181-0/+5
| | | | | | | | | | | | Fixes #18905. `#touch` now takes time as an option. Setting the option saves the record with the updated_at/on attributes set to the current time or the time specified. Updated tests and documentation accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | Use SQL COUNT and LIMIT 1 queries for none? and one? methods if no block or limit is given, instead of loading the entire collection to memory. The any? and many? methods already follow this behavior. [Eugene Gilburg & Rafael Mendonça França]

* | | Refactor enum to be defined in terms of the attributes APISean Griffin2015-02-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In addition to cleaning up the implementation, this allows type casting behavior to be applied consistently everywhere. (#where for example). A good example of this was the previous need for handling value to key conversion in the setter, because the number had to be passed to `where` directly. This is no longer required, since we can just pass the string along to where. (It's left around for backwards compat) Fixes #18387
* | | `current_scope` shouldn't pollute sibling STI classesSean Griffin2015-02-111-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It looks like the only reason `current_scope` was thread local on `base_class` instead of `self` is to ensure that when we call a named scope created with a proc on the parent class, it correctly uses the default scope of the subclass. The reason this wasn't happening was because the proc captured `self` as the parent class, and we're not actually defining a real method. Using `instance_exec` fixes the problem. Fixes #18806
* | | fix `remove_reference` with `foreign_key: true` on MySQL. #18664.Yves Senn2015-02-111-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MySQL rejects to remove an index which is used in a foreign key constraint: ``` ActiveRecord::StatementInvalid: Mysql2::Error: Cannot drop index 'index_copies_on_title_id': needed in a foreign key constraint: ALTER TABLE `copies` DROP `title_id` ``` Removing the constraint before removing the column (and the index) solves this problem.

* | | | Respect custom primary keys for associations in `Relation#where`Sean Griffin2015-02-041-0/+6
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | While we query the proper columns, we go through normal handling for converting the value to a primitive which assumes it should use the table's primary key. If the association specifies a different value (and we know that we're working with an association), we should use the custom primary key instead. Fixes #18813.
* | | Correct errors in counter cache updatingSean Griffin2015-02-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cache name should be converted to a string when given, not compared as a symbol. This edge case is already adequately covered by our tests, but was masked by another issue where we were incorrectly updating the counter cache twice. When paired with a bug where we didn't update the counter cache because we couldn't find a match with the name, this made it look like everything was working fine. Fixes #10865.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes #17621. This 5 year old (or older) issue causes validations to fire when a parent record has `validate: false` option and a child record is saved. It's not the responsibility of the model to validate an associated object unless the object was created or modified by the parent. Clean up tests related to validations `assert_nothing_raised` is not benefiting us in these tests Corrected spelling of "respects" It's better to use `assert_not_operator` over `assert !r.valid`

| * | | Don't redefine autosave association callbacks in nested attrsSean Griffin2015-01-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These callbacks will already have been defined when the association was built. The check against `reflection.autosave` happens at call time, not at define time, so simply modifying the reflection is sufficient. Fixes #18704
| * | | Move integer range validation to never raise on assignmentSean Griffin2015-01-231-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given that this was originally added to normalize an error that would have otherwise come from the database (inconsistently), it's more natural for us to raise in `type_cast_for_database`, rather than `type_cast_from_user`. This way, things like numericality validators can handle it instead if the user chooses to do so. It also fixes an issue where assigning an out of range value would make it impossible to assign a new value later. This fixes several vague issues, none of which were ever directly reported, so I have no issue number to give. Places it was mentioned which I can remember: - https://github.com/thoughtbot/shoulda-matchers/blob/9ba21381d7caf045053a81f32df7de2f49687820/lib/shoulda/matchers/active_model/allow_value_matcher.rb#L261-L263 - https://github.com/rails/rails/issues/18653#issuecomment-71197026

| * | Introduce `ActiveRecord::Base#accessed_fields`Sean Griffin2015-01-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This method can be used to see all of the fields on a model which have been read. This can be useful during development mode to quickly find out which fields need to be selected. For performance critical pages, if you are not using all of the fields of a database, an easy performance win is only selecting the fields which you need. By calling this method at the end of a controller action, it's easy to determine which fields need to be selected. While writing this, I also noticed a place for an easy performance win internally which I had been wanting to introduce. You cannot mutate a field which you have not read. Therefore, we can skip the calculation of in place changes if we have never read from the field. This can significantly speed up methods like `#changed?` if any of the fields have an expensive mutable type (like `serialize`) ``` Calculating ------------------------------------- #changed? with serialized column (before) 391.000 i/100ms #changed? with serialized column (after) 1.514k i/100ms ------------------------------------------------- #changed? with serialized column (before) 4.243k (± 3.7%) i/s - 21.505k #changed? with serialized column (after) 16.789k (± 3.2%) i/s - 84.784k ```
