按照django website上的示例,我正在尝试上传文件,对内容进行检查,然后反馈给用户并存储文件内容。
但是,request.FILES总是空的,我遇到了麻烦。我的代码如下(注意print语句后的输出):
**forms.py**
class UploadFileForm(forms.Form):
data_import = forms.FileField()
class Meta:
model = Recipe
fields = ('data_import',)
**view**
def recipes_list(request):
template = 'recipes/recipes_list.html'
if request.method == 'GET':
user = request.user
queryset = Recipe.objects.filter(user=user)
form = UploadFileForm()
return render(request, 'recipes/recipes_list.html', context={'recipes': queryset, 'form': form})
elif request.method == 'POST':
print(request.FILES) # <MultiValueDict: {}>
print(request.POST) # <QueryDict: {'csrfmiddlewaretoken': ['...'], 'data_import': ['recette.json']}>
form = UploadFileForm(request.POST, request.POST.data_import)
if form.is_valid():
return HttpResponseRedirect(template)
else:
print(form.errors)
**template**
<form method="post">
{% csrf_token %}
{{ form }}
<button type="submit">submit</button>
</form>
我得到的错误是:
<ul class="errorlist"><li>data_import<ul class="errorlist"><li>This field is required.</li></ul></li></ul>
但是我可以看到该文件已上传,并且位于request.POST.get('data_import')
中。
我想在表单上运行验证,但是如果request.FILES为空,我将无法执行此操作。
我显然做错了什么,有人可以指出我正确的方向吗?
答案 0 :(得分:1)
<form method="post" enctype= multipart/form-data>
{% csrf_token %}
{{ form }}
<button type="submit">submit</button>
</form>
将表格更改为上一页
