Simon Charette 0cf85e6b07 Refs #29908 -- Optimized known related objects assignment.
Since CPython implements a C level attrgetter(*attrs) it even outperforms the
most common case of a single known related object since the resulting attribute
values tuple is built in C.

Simon Charette 75dfa92a05 Fixed #29908 -- Fixed setting of foreign key after related set access if ForeignKey uses to_field.
Adjusted known related objects handling of target fields which relies on
from and to_fields and has the side effect of fixing a bug bug causing

Sanyam Khurana 83c7096f2a Fixed #29869 -- Made UUIDField.to_python() convert integers. 2018-10-24 20:26:57 -04:00
Simon Charette 5e3463f6bc Fixed #27595 -- Made ForeignKey.get_col() follow target chains.
Previously, foreign relationships were followed only one level deep which
prevents foreign keys to foreign keys from being resolved appropriately.
This was causing issues such as improper database value conversion for
UUIDField on SQLite because the resolved expression's output field's
internal type wasn't correct. Added tests to make sure unlikely foreign
reference cycles don't cause recursion errors.

Refs #24343.

Thanks oyooyo for the report and Wayne Merry for the investigation.

aspalding 834c4ec8e4 Moved make_hashable() to django.utils and added tests. 2018-10-17 11:17:23 -04:00
Florian Apolloner bc7dd8490b Fixed #21171 -- Avoided starting a transaction when a single (or atomic queries) are executed.
Checked the following locations:

 * Model.save(): If there are parents involved, take the safe way and use
   transactions since this should be an all or nothing operation.

   If the model has no parents:

    * Signals are executed before and after the previous existing
      transaction -- they were never been part of the transaction.

    * if `force_insert` is set then only one query is executed -> atomic
      by definition and no transaction needed.

    * same applies to `force_update`.

    * If a primary key is set and no `force_*` is set Django will try an
      UPDATE and if that returns zero rows it tries an INSERT. The first
      case is completly save (single query). In the second case a
      transaction should not produce different results since the update
      query is basically a no-op then (might miss something though).

 * QuerySet.update(): no signals issued, single query -> no transaction
   needed.

 * Model/Collector.delete(): This one is fun due to the fact that is
   does many things at once.

   Most importantly though: It does send signals as part of the
   transaction, so for maximum backwards compatibility we need to be
   conservative.

   To ensure maximum compatibility the transaction here is removed only
   if the following holds true:

     * A single instance is being deleted.
     * There are no signal handlers attached to that instance.
     * There are no deletions/updates to cascade.
     * There are no parents which also need deletion.

should make sure the fallback logic is only performed if required.
