[FIXED] Django orm queries with left varaible is not certain

Issue

I want to make a query like this:

Student.objects.filter(id= id).update(name=value)       

And the value comes from the user.

But the problem is that I'm not only to update name but also update some other information like address or phone number. I don't want to create duplicated codes like:

Student.objects.filter(id= id).update(address=value)        
Student.objects.filter(id= id).update(phone_number=value)       

I only want to have one line code like:

Student.objects.filter(id= id).update(XXX=XXX_value)        

So I wonder if I can assign any variable to the left varaible inside update function or not.

Sorry, the left key is not a certain value. It depends on the user's post. It might be an address or just name next time. It's not a fixed value.

Thanks.

Solution

You can dynamically define the fields by providing them in a dictionary and using ** to unpack the dictionary into arguments for update().

fields_to_update = {
    "address": address_value,
    "phone_number": phonenumber_value,
}
Students.objects.filter(id=update_id).update(**fields_to_update)
