Can I get the value of an object field some other way than obj.field? Does something like obj.get('field') exist? Same thing for setting the value of the field.

Creating objects To create an object, instantiate it using keyword arguments to the model class, then call save() to save it to the database. This performs an INSERT SQL statement behind the scenes. Django doesn't hit the database until you explicitly call save() . The save() method has no return value.
str function in a django model returns a string that is exactly rendered as the display name of instances for that model.
A ManyToManyField in Django is a field that allows multiple objects to be stored. This is useful and applicable for things such as shopping carts, where a user can buy multiple products. To add an item to a ManyToManyField, we can use the add() function.
To get the value of a field:
getattr(obj, 'field_name') To set the value of a field:
setattr(obj, 'field_name', 'field value') To get all the fields and values for a Django object:
[(field.name, getattr(obj,field.name)) for field in obj._meta.fields] You can read the documentation of Model _meta API which is really useful.
