#32410: JSONField(default=list) causes validation error in Django Admin when populated with default [] value -----------------------------------------+--------------------------- Reporter: eldavo | Owner: nobody Type: Bug | Status: new Component: contrib.admin | Version: 3.1 Severity: Normal | Keywords: JSONField Triage Stage: Unreviewed | Has patch: 0 Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 1 | -----------------------------------------+--------------------------- Environment: Django 3.1.5, Python 3.8.7, MariaDB 10.5.6
Expected behavior: I should be able to edit an object that contains a JSONField with default=list without having any validation errors if I save without changing the JSONField. Steps to reproduce: 1. Define a field in an Object using models.JSONField(default=list). 2. Create a new Object. 3. Go to edit view of that Object in Django Admin. You will see the default [] empty list in the JSONField. Don’t change any field. 4. Click Save; without having changed anything, you’ll receive a validation error that “This field is required” 5. Workaround: put quotes around the "[]” or replace with any valid JSON object. If you try to put random characters in the field you'll receive a "Enter a valid JSON." validation.
