Django上传没有模型的文件 [英] django uploading files without model
问题描述
我想上传没有模型的文件(文本/图像)(仅使用视图和模板).理想情况下，我想读取或写入位置.
I would like to upload files (text/images) without a model ( just using views and templates). I would ideally like to read or write to location.
我当前的代码如下:
在我的模板/foo/help/UploadFileContent.html
In my template /foo/help/UploadFileContent.html
<!doctype html>
<html>
<body>
<link rel="stylesheet" href="{{STATIC_URL}}/stylesheets/jquery-ui.css">
<div class="main-content">
<div class="container">
<div class="container">
<div class="row">
<div class="box">
<div class="box-content">
<div class="col-md-12">
<form method="post" id="fileupload" action="/helpsubmitfilecontent/" accept-charset="utf-8" class="fill-up">
{% csrf_token %}
<div class="row">
<div class="col-lg-4">
<ul class="padded separate-sections">
<li>
<input type="text" name="name" id="name" placeholder="Name"/>
</li>
<li>
<textarea name="content" id="content"
placeholder="Help Contents" style="height: 250px;width: 700px"></textarea>
</li>
<li>
<input type="file" name="myfile" id="myfile" />
</li>
</ul>
<div class="form-actions">
<button type="submit" class="btn btn-blue">Submit</button>
</div>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</body>
<script>
$('#fileupload').submit(function(evnt){
if($('#name').val().length <=0){
$('#name').attr('style','border-color:red');
evnt.preventDefault();
}
if($('#content').val().length <=0){
$('#content').attr('style','border-color:red');
evnt.preventDefault();
}
});
</script>
</html>
在我的帮助视图中:
def fileupload(request):
return responsewrapper('pages/foo/help/UploadFileContent.html', locals(),request)
def submitfilecontent(request):
myhash = dict()
myhash['name'] = request.POST['name'] # works
myhash['filedata'] = request.POST['content'] # works
handle_uploaded_file(request.FILES['myfile']) # error throws up here.
return HttpResponseRedirect("/successupload")
def handle_uploaded_file(f):
destination = open('/home/foo/name.txt', 'wb+')
for chunk in f.chunks():
destination.write(chunk)
destination.close()
对文件数据进行操作时会引发以下错误.
The following error throws up while operating on the file data.
Exception Value:
"Key 'myfile' not found in <MultiValueDict: {}>"
请咨询.理想情况下，我不希望使用任何数据库，因为我想要的只是将文本/图像导入到静态位置.
Please advice. I would ideally not like to use any databases, as all i want is to import text/images to static location.
推荐答案
您在< form> 中缺少了 enctype ="multipart/form-data" 属性code>标签.
You're missing the enctype="multipart/form-data" attribute in your <form> tag.
修改
handle_uploaded_file 的参数(您称为 f )是UploadedFile的一个实例，根据
The argument to handle_uploaded_file, which you've called f, is an instance of UploadedFile, which according to the docs has a name attribute, so you could presumably change the destination depending on the name. Or you could look at the contents themselves and determine it that way.
