How to get the value of a Django Model Field object

Question

I got a model field object using field_object = MyModel._meta.get_field(field_name). How can I get the value (content) of the field object?

Answer 1

Use value_from_object:

field_name = 'name'
obj = MyModel.objects.first()
field_object = MyModel._meta.get_field(field_name)
field_value = field_object.value_from_object(obj)

Which is the same as getattr:

field_name = 'name'
obj = MyModel.objects.first()
field_object = MyModel._meta.get_field(field_name)
field_value = getattr(obj, field_object.attname)

Or if you know the field name and just want to get value using field name, you do not need to retrieve field object firstly:

field_name = 'name'
obj = MyModel.objects.first()
field_value = getattr(obj, field_name)
