问题描述
我正在尝试使用POST / FILE请求中的数据填充Django表单集。我可以填充FileField以外的所有字段。似乎 initial 不能用于将request.FILE传递给FormSet创建者函数。我的问题是如何将FILE传递给FormSet。
I am trying to populate a Django formset using data from a POST/FILE request. I am able to populate all the fields except the FileField. It seems that initial cannot be used to pass the request.FILE to the FormSet creator function. My question is how to pass the FILE to FormSet.
model.py
class ArticleForm(forms.Form):
docfile = forms.FileField()
subject = forms.Charfield(max_length=128)
ArticleFormSet = formset_factory(ArticleForm, extra=2)
views.py
formset = ArticleFormSet(request.POST, request.FILE)
#do some other work, and then re-display the POST data
data = formset.cleaned_data
formset = ArticleFormSet(initial=data)
return render_to_response('some.html',
{'formset':formset}
)
推荐答案
您不能将初始数据传递给文件字段。
当浏览器呈现时，< input type =file/> 将始终为空。
You can not pass initial data to a file field.The <input type="file" /> will always be blank when the browser renders it.
要将 request.FILES 传递给表单，只需在POST后将其指定为第二个参数。
To pass request.FILES to a formset, just specify it as the second argument after POST.
FormSet（request.POST，request.FILES）
