Assigning value to the JSON attribute

Usually, a JSON structure contains a combination of dictionaries and lists containing simple types, such as numbers, strings and boolean. Let’s create a couple of objects with a simple JSON structure:

  1. p1 = Product(name='Samsung Galaxy S7 edge',
  2.              info={
  3.                  'display': {
  4.                     'size': 5.5,
  5.                  },
  6.                  'battery': 3600,
  7.                  '3.5mm jack': True,
  8.                  'SD card slot': True,
  9.                  'colors': ['Black', 'Grey', 'Gold'],
  10.              },
  11.              tags=['Smartphone', 'Samsung'])
  13. p2 = Product(name='iPhone 6s',
  14.              info={
  15.                  'display': {
  16.                     'size': 4.7,
  17.                     'resolution': [750, 1334],
  18.                     'multi-touch': True,
  19.                  },
  20.                  'battery': 1810,
  21.                  '3.5mm jack': True,
  22.                  'colors': ['Silver', 'Gold', 'Space Gray', 'Rose Gold'],
  23.              },
  24.              tags=['Smartphone', 'Apple', 'Retina'])

In Python code a JSON structure is represented with the help of the standard Python dict and list. In our example, the info attribute is assigned with a dict. The tags attribute keeps a list of tags. These attributes will be serialized to JSON and stored in the database on commit.
