Update only specific fields in a models.Model Django

March 21, 2024

I have an APP to rate supervisors to personnel in Django.

I have model in models.py in my app Django :

class SuperviserModel(models.Model):
    name = models.TextField(db_collation='C')  
    family = models.TextField(db_collation='C')  
    score = models.FloatField(db_column='score ', blank=True, null=True)  # 
    def __str__(self)-> str:
        return f' -  {self.family}  - {self.name}'
    class Meta:
        managed = False
        db_table = 'personnel'

And in admin.py:

@admin.register(SuperviserModel)
class MySuperviserModelAdmin(admin.ModelAdmin):
    list_display = ['name','family','score']
    sortable_by = ['name','family']
    search_fields=['name', 'family']

I want when superviser user edit personnel just update score field, And cant update name and family field.

How can I do?

>Solution :

Specify score as only .fields ^[Django-doc]:

@admin.register(SuperviserModel)
class MySuperviserModelAdmin(admin.ModelAdmin):
    list_display = ['name', 'family', 'score']
    sortable_by = ['name', 'family']
    search_fields = ['name', 'family']
    fields = ['score']
