models.py

from django.db import models


class Post(models.Model):

    title = models.CharField(max_length=50)
    content = models.CharField(max_length=500)
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return str(self.id) + " - " + self.title

Serializerのcreateをそのまま使ってしまうとパスワードが暗号化されずにデータベースに保存されてしまう。

created_atの形式を変更します。何年何月何日何時何分何秒。

created_at = serializers.DateTimeField(format="%Y-%m-%d %H:%M:%S", read_only=True)
