Django 5.2 bulk_create ignore_conflicts primary key not set returned objects documentation

💡 Result:

In Django 5.2, when you use the ignore_conflicts=True parameter in QuerySet.bulk_create(), Django explicitly disables setting the primary key attribute on the model instances [1][2][3]. This behavior occurs because, when conflict handling (such as ignore_conflicts=True) is enabled, the underlying database operation often does not return the primary keys of the inserted rows in a reliable way that maps directly back to the original list of objects [2][4]. Consequently, if your model uses an auto-incrementing primary key, the instances passed to bulk_create() will not have their primary key fields updated with the values generated by the database [1][3]. Key technical points: - Documentation/Behavior: It is a documented limitation that ignore_conflicts=True prevents the setting of primary keys on model instances [1][2][3]. - Reasoning: Because the database ignores conflicting rows, it may not return a result set that corresponds 1:1 with the input objects, making it impossible for Django to safely assign the correct primary keys back to the instances [4]. - Related Effects: Because primary keys are not set, you may encounter issues if you attempt to use these instances immediately in relationships (e.g., assigning an unsaved instance to a ForeignKey field), as the primary key will be None [2][3]. If you need to retrieve primary keys after a bulk operation, you must either avoid using ignore_conflicts=True or perform the insertions in a way that allows the database to return the IDs (such as standard insertions or specific database-level workarounds) [1][2]. Note that while Django has improved support for returning primary keys in other contexts (such as update_conflicts=True in some scenarios [5]), ignore_conflicts=True remains restricted in this regard [1].

Bind issue and exclude ignored conflicts from activity records.

create() loads issue at line 272 without assigning it, so every non-empty request raises NameError before bulk_create(). Iterate over new_issues when constructing CycleIssue objects. Then ensure ignored conflicts are not serialized as newly created activity records because bulk_create(..., ignore_conflicts=True) leaves their automatic primary keys unset.

In `@apps/api/plane/app/views/cycle/issue.py` at line 275, Update create() to
assign the issue loaded before bulk_create and iterate over new_issues when
constructing CycleIssue objects, avoiding the NameError for non-empty requests.
When creating activity records afterward, exclude entries whose bulk-created
primary key remains unset because their conflict was ignored.
