What it the difference between running two commands:
foo = FooModel()
and
bar = BarModel.objects.create()
Does the second one immediately create a BarModel
in the database, while for FooModel
, the save()
method has to be called explicitly to add it to the database?
A model is the single, definitive source of information about your data. It contains the essential fields and behaviors of the data you're storing. Generally, each model maps to a single database table. The basics: Each model is a Python class that subclasses django.
Conclusion: Model. objects. create() internally do model initialization and perform save with force_insert=True .
To create a new instance of a model, instantiate it like any other Python class: class Model (**kwargs) The keyword arguments are the names of the fields you've defined on your model. Note that instantiating a model in no way touches your database; for that, you need to save() .
Django web applications access and manage data through Python objects referred to as models. Models define the structure of stored data, including the field types and possibly also their maximum size, default values, selection list options, help text for documentation, label text for forms, etc.

To create and save an object in a single step, use the
create()
method.
