Methods for adding JSON type fields to model models in Django

The example in this article describes the method of adding JSON-type fields to model models in Django. Share to everyone for your reference. Specific as follows:

Django has the model used in the JSON field, adding a Jsonfield automatic type as follows:

Class Jsonfield (models. TextField):   __metaclass__ = models. Subfieldbase   Description = "Json"   def to_python (self, value):     v = models. Textfield.to_python (self, value)     try:       return json.loads (v) [' V ']     except:       pass     return v   def Get_prep_value (self, value):     

The Jsonfield type field is then defined directly for the model.

Class Category (models. Model):   name = fields. Medialnamefield ()   

Very convenient to use:
Copy the Code code as follows:

Category.objects.create (name= "C1", other= (1,2,3,4,5))

All types that can be serialized by JSON can be directly assigned to the other field, which is handy.

Hopefully this article will help you with Python programming.
