從Django管理面板上傳圖像到數據庫

Question

這裏是我的model.py

from django.db import models 

class Flower(models.Model): 
    name = models.CharField(max_length = 30) 
    price = models.IntegerField() 
    image = models.ImageField(upload_to = 'static/media') 
    def __unicode__(self): 
     return self.name 

urls.py

from django.conf.urls import patterns, include, url 

from django.contrib import admin 
admin.autodiscover() 

    urlpatterns = patterns('', 
     # Examples: 
     url(r'^$', 'site1.views.home', name='home'), 
     # url(r'^mysite1/', include('mysite1.foo.urls')), 

     # Uncomment the admin/doc line below to enable admin documentation: 
     # url(r'^admin/doc/', include('django.contrib.admindocs.urls')), 

     # Uncomment the next line to enable the admin: 
     url(r'^admin/', include(admin.site.urls)), 
    ) 

admin.py

from django.contrib import admin 
from site1.models import Flower 

admin.site.register(Flower) 

完全回溯

Exception Type: DatabaseError at /admin/site1/flower/ 
Exception Value: no such column: site1_flower.image 

我想從管理面板將圖像上傳到我的網站數據庫，因此我可以在任何需要的位置查看此圖像。 但我遇到了一個錯誤：

DatabaseError at /admin/site1/flower/ 
no such column: site1_flower.image 
Request Method: GET 
Request URL: http://127.0.0.1:8000/admin/site1/flower/ 
Django Version: 1.4.3 
Exception Type: DatabaseError 
Exception Value:  
no such column: site1_flower.image 

我該如何克服這個問題。

Answer 1

根據* Exception Value：no such column：site1_flower.image * 我想，你在syncdb後添加了圖像字段。所以，圖像字段不存在於數據庫。 最簡單的方法是根本刪除Flower模型並再次運行syncdb。 或者您可以在您的數據庫中手動創建該字段。 但最好的方法是使用django south
