在 Django 中创建一个 model ，其字段中包含多个其他字段

Question

I'm quite new to Django and would like to clear a noob doubt. Say I have a post request to a model Scans in django.

The json data for the same looks like

[{"id":1, "results":{"low": 3, "medium": 6, "high": 7}, "machine": "Windows", "report": "yes"]

How should the model look like? I can't figure out what field type I should give to results .

Answer 1

Try out JSONField . Your model should look like that.

from django.contrib.postgres.fields import JSONField
from django.db import models

class Scans(models.Model):
    machine = models.CharField(...)
    results = JSONField(default=dict)

PS You need to configure your database(in this case PostgreSQL)

PSS If you dont want to use PostgreSQL here is JSONFIeld for MySQL

Answer 2

You can also create two models Scans and Results and create a relationship between them as follows

class Scans(models.Model):
    machine = models.CharField(max_length = 100)
    # assuming that report is by default false
    report = models.BooleanField(default = False)
    results = models.ForeignKey(Results, on_delete = models.CASCADE) 


class Results(models.Model):
    low = models.IntegerField()
    medium = models.IntegerField()
    high = models.IntegerField()
