我目前正在为网站制作个人资料图片功能,我开始使用DropzoneJS,但我在提交文件时遇到了问题。图片会很好地落入区域,但它会出现在" X"在它上面,当我将鼠标悬停在图片上时,我可以看到MultiValueDictKeyError
错误。当我单击提交按钮而不选择文件时,我得到的错误是相同的。所以我认为问题是该文件不是由button
提交的?我该怎么做?
HTML / JS:
<script type='text/javascript'>
Dropzone.options.myDropzone = {
init : function() {
var submitButton = document.querySelector("#submitBtn")
myDropzone = this;
submitButton.addEventListener("click", function() {
myDropzone.processQueue();
});
this.on("addedfile", function() {
document.getElementById('submitBtn').style.visibility = "visible";
});
this.on('addedfile', function(){
if (this.files[1]!=null){
this.removeFile(this.files[0]);
}
});
}
};
Dropzone.options.myAwesomeDropzone = {
accept: function(file, done) {
console.log("uploaded");
},
init: function() {
this.on("addedfile", function() {
if (this.files[1]!=null){
this.removeFile(this.files[0]);
//document.getElementById('submitBtn').style.visibility = "visible";
}
});
}
};
</script>
<!-- Modal -->
<div id="picModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<span class="close"></span>
<form action="{% url 'profile_test' %}" method='POST' enctype="multipart/form-data" class="dropzone" id="my-dropzone">{% csrf_token %}
<button id='submitBtn' type='submit' style='visibility: hidden;'> Submit </button>
<input id='submit-all' type='file' name='uploaded_image'/>
{{form}}
</form>
</div>
</div>
</body>
修改
我将autoProcessQueue: false,
添加到myDropzone
。当我将鼠标悬停在图片上时,我没有得到这个问题。相反,现在当我按提交时,它只是带我到MultiValueDictKeyError
错误页面
*编辑2 **
views.py
def profile_test(request):
#going to use this view to display the profile page, and test alterations to it
form = ImageUploadForm(request.POST, request.FILES)
user = User.objects.get(id=request.user.id)
if request.method == "POST":
print 'valid'
user.userprofile.img = request.POST.get('uploaded_image', False)
user.userprofile.save()
return HttpResponseRedirect(reverse("profile_test"))
else:
print 'invalid'
form = ImageUploadForm()
return render(request, 'profile_test.html', {form:'form', user: 'user'})
我曾经user.userprofile.img = request.FILES["uploaded_image"]
但改变了它,似乎更好地改变了事情。现在图像将落入区域,当我将鼠标悬停在区域上时,我不会看到该错误。但是现在当我提交它时,dropzone消失了,而配置文件pic也没有改变。
答案 0 :(得分:2)
我希望img属性是FileField。正确?
user.userprofile.img = request.POST.get('uploaded_image', False)
请试试这个。
user.userprofile.img = request.FILES.get('uploaded_image')
# if you have multiple files to upload
user.userprofile.img = request.FILES.getlist('uploaded_image')
