#26833: alter_field() fails to drop indexes on columns with mixed case on Oracle ----------------------------+-------------------- Reporter: jdufresne | Owner: nobody Type: Bug | Status: new Component: Migrations | Version: master Severity: Normal | Keywords: Triage Stage: Unreviewed | Has patch: 0 Easy pickings: 0 | UI/UX: 0 ----------------------------+-------------------- On fields that set `db_column` with mixed case, `alter_field()` fails to drop indexes on Oracle.
Due to Oracle's `uppercases_column_names` feature, [https://github.com/django/django/blob/8db889eaf7dce0cb715b075be32047c1b1b316da/django/db/backends/oracle/introspection.py#L158 get_constraints() returns all columns as lower case]. However, `alter_field()` use of [https://github.com/django/django/blob/8db889eaf7dce0cb715b075be32047c1b1b316da/django/db/backends/base/schema.py#L938-L961 _constraint_names()] compares the column name as set by `db_column`. This must be accounted for on Oracle for the index to be properly dropped. -- Ticket URL: <https://code.djangoproject.com/ticket/26833> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
