难以将文件上传到 FileField,表单无效
Difficulty uploading a file to a FileField, form isn't valid
晕,我正在尝试使用文件字段上传文件。但我总是失败。当语句 form.errors.as_data()
执行时,浏览器 return 'tempfile'。我已经尝试从 Django 文档和一些 Django 参考资料中找到解决方案。但是,还是修不了。 ;(
这是我的 view.py
def dataprocessing(request):
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
import pdb; pdb.set_trace()
newdoc = Document(docfile=request.FILES['myfile'])
newdoc.save()
#Redirect to the dataprocessing after POST
#return render(request, 'dataprocessing.html')
return HttpResponse("success")
else:
return HttpResponse(form.errors.as_data())
else:
import pdb; pdb.set_trace()
form = DocumentForm() #A empty, unbound form
return render(request, 'dataprocessing.html', {'form': form})
models.py
class Document(models.Model):
docfile = models.FileField(upload_to='documents/%Y/%m/%d')
forms.py
class DocumentForm(forms.Form):
tempfile = forms.FileField()
和dataprocessing.html
<form method="post" enctype="multipart/form-data" action="{% url "dataprocessing" %}">
<div class="form-group">
<label for="up">Input Data</label> {% csrf_token %}
<input type="file" name=myfile class="filestyle" data-buttonName="btn-primary" data-buttonBefore="true" data-size="sm" accept="application/vnd.ms-excel, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
id="up">
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary btn-block">Upload Data</button>
<button type="button" class="btn btn-primary btn-block">Download Template</button>
</div>
</form>
像这样使用 forms.ModelForm
instaed forms.Form
怎么样?
# forms.py
class DocumentForm(forms.Model):
class Meta:
model = Document
fields = ['tempfile']
并让你的 views.py
像这样:
# views.py
def dataprocessing(request):
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponse("success")
else:
return HttpResponse(form.errors.as_data())
else:
form = DocumentForm() #A empty, unbound form
return render(request, 'dataprocessing.html', {'form': form})
这使得 form
对象可以直接保存到您的模型中。
