我是个新手,上传文件,在它的代码,以便即时通讯相当糟糕。我使用Django作为框架。目前这是我的用户输入html代码。如何重新命名输入文本
<html>
<head>
<title>uploader</title>
<style>
h1 {
font-size: 2em;
font-weight: bold;
color: #777777;
text-align: center
}
table {
margin: auto;
}
a {
text-decoration: none
}
</style>
</head>
<body>
<h1>
{{what}}
<h3><p style="text-align: left;text-decoration: none;"><a href="{% url 'home' %}">Back</p></a></h3>
</h1>
<hr>
<table>
<tr>
<td>
<form action="upload/" method="POST" enctype="multipart/form-data">
{% csrf_token %}
<fieldset>
Category of the device:<br>
<input type="text" name="category" value="" required id="cat">
<br>
Model:<br>
<input type="text" name="model" value="" required id="mod">
<br>
<input type="submit" value="Upload File" class="submit" name="submit" />
<input type="file" name="file"/>
</fieldset>
</form>
</td>
</tr>
</table>
</body>
</html>
views.py
def home(request):
return render(request, 'index.html', {'what':'Upload Files'})
def upload(request):
try:
if request.method == 'POST' and request.FILES['file']:
try:
myfile = request.FILES['file']
category = request.POST['category']
model = request.POST['model']
validate_file_extension(myfile)
fs = FileSystemStorage(location='uploaded/')
filename = request.FILES['filename'].name
handle_uploaded_file(request.FILES['file'], str(request.FILES['file']))
modified_name = "{}_{}_{}".format(filename, category, modle)
filename = fs.save(modified_name, myfile)
return redirect("/success")
except:
return redirect("/unsuccessful")
except:
return redirect("/upload")
def handle_uploaded_file(file, filename):
if not os.path.exists('uploaded/'):
os.mkdir('uploaded/')
with open('uploaded/' + filename, 'wb+') as destination:
for chunk in file.chunks():
destination.write(chunk)
我如何重命名上传的用户具有的文字,他们输入自己的文件名后面用“_”的文件。
如:
filename = myfile
category = camera
model = XYZ123
该文件应该被重新命名为 “myfile_camera_XYZ123”。
你必须做,在视图中。你可以发布吗? –
当然!我编辑过它 –
与模型相关联的形式? –
