各位大大好小弟最近開始學django,跟著“it's django-用python迅速打造web應用”學習但在建立modle跟資料庫同步時遇到錯誤訊息,而我用的環境是python2.7＋django1.8 django.db.utils.OperationalError: table restaurants_food__new has no column named name 但我並沒有建立叫 restaurants_food__new 的 table 啊？？底下是我的models.py 內容 from django.db import models # Create your models here. class Restaurant(models.Model): name = models.CharField(max_length=20) phone_number = models.CharField(max_length=15) address = models.CharField(max_length=50, blank=True) class Food(models.Model): name = models.Field(max_length=20) price = models.DecimalField(max_digits=3,decimal_places=0) comment = models.CharField(max_length=50, blank=True) is_spicy = models.BooleanField(default=False) restaurant = models.ForeignKey(Restaurant) 底下是完整錯誤訊息 -> python manage.py migrate restaurants 0001 Operations to perform: Target specific migration: 0001_initial, from restaurants Running migrations: Rendering model states...
