502 Bad Gateway Django [英] 502 Bad Gateway Django

问题描述

我有一个简单的应用程序，允许您将图像上传到服务器上，并将其设置在由django + uwsgi + ngnix组成的生产服务器上。

尝试上传图片时出现问题。我收到以下错误：

错误

  502 Bad Gateway 
 nginx / 1.2.1 
  

功能：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $
$ csrf（request））


如果request.POST：
form = ImageForm（request.POST，request.FILES）
如果form_is.valid（）：

image = request.FILES.get（'image'）
CarPhoto.objects.create（user = request.user，cars = 1，description ='dwq'，image = image）
return HttpResponseRedirect（reverse（'transformer：kevin'））
return render_to_response（'image.html'，context，context_instance = RequestContext（request））

解决方案

如果您的项目中包含第三方应用程序，那么它应该安装在您的服务器上，也就像南方是第三方应用程序。
考虑南方包含在您的settings.py文件中，然后南方也应该安装在您的服务器上。
如果该模块在这里考虑到这里，已经安装在服务器上，然后尝试升级它。因为您可能在本地机器上使用升级版本的模块，而在服务器中安装的是旧版本。

I have a simple application that allows you to upload images onto the server, and it is set up on my production server which consist of django + uwsgi + ngnix .

I have a problem when trying to upload an image. I get the following error:

error

502 Bad Gateway
nginx/1.2.1

function:

def upload(request):
    form = ImageForm()
    context = {'form':form,}
    context.update(csrf(request))


    if request.POST:
        form = ImageForm(request.POST, request.FILES)
        if form_is.valid():

            image = request.FILES.get('image')
            CarPhoto.objects.create(user=request.user,cars=1,description='dwq',image=image)
            return HttpResponseRedirect(reverse('transformer:kevin'))
    return     render_to_response('image.html',context,context_instance=RequestContext(request))

template

 <form method="POST" enctype="multipart/form-data" action=".">

 {% csrf_token %}
 <div id="c">image</div> {{form.image}}
    <input type = "submit" value= "add" id="box2"/>
 </form>

解决方案

if third party app included in your project then it should be installed on your server also like south is third party app. Consider south is included in your settings.py file then south should be installed on your server also. If that module consider south here, is already installed on server then try to upgrade it. Because it is possible that you are using upgraded version of module on local machine and older version is installed in the server.
