I am working with Django 1.8 and Dropzone JS file upload package
我正在使用Django 1.8和Dropzone JS文件上传包
I want to add a gallery (my galleries are called 'fountains') and then add photos to the gallery.
我想添加一个画廊（我的画廊被称为'喷泉'），然后将照片添加到画廊。
Here is my work flow:
这是我的工作流程：
- add gallery using model form
- 使用模型表单添加图库
- redirect to gallery view
- 重定向到图库视图
- gallery view has a auto generated link that goes to a photo_upload view so user can add photos to new gallery
- 图库视图有一个自动生成的链接，可以转到photo_upload视图，因此用户可以将照片添加到新图库
- photo_upload view/template uses Dropzone javascript add-in
- photo_upload视图/模板使用Dropzone javascript加载项
- photos are uploaded via dropzone, photo details are written to Photos model/table including the new gallery id as foreign key
- 照片通过dropzone上传，照片详细信息将写入照片模型/表格，包括新的图库ID作为外键
I can successfully upload photos with Dropzone when I do not pass the pk from the gallery. So I am pretty sure this is not my problem.
当我没有从画廊传递pk时，我可以使用Dropzone成功上传照片。所以我很确定这不是我的问题。
However, the photo_upload view is giving me an error when i enter url as follows:
但是，当我输入url时，photo_upload视图给出了一个错误，如下所示：
http://localhost:8000/photo_upload/17/
This link corresponds to a url in urls.py and it finds the photo_upload view but it produces the following message when resolving view.
此链接对应于urls.py中的url，它会找到photo_upload视图，但在解析视图时会生成以下消息。
NoReverseMatch at /photo_upload/17/
Reverse for 'photo_upload' with arguments '()' and keyword arguments '{}' not found. 1 pattern(s) tried: ['photo_upload/(?P<id>\\d+)/$']
I am looking for any insight why the photo_upload view is giving this error. Any other tips etc to make this better appreciated too.
我正在寻找任何有关为什么photo_upload视图给出此错误的见解。任何其他提示等，使这更好地赞赏。
My models:
我的模特：
class Fountains(models.Model):
foun_name = models.CharField(max_length=100, blank=True, null=True)
foun_desc = models.TextField(blank=True, null=True)
foun_address = models.CharField(max_length = 100, blank=True, null=True)
foun_lat = models.CharField(max_length=20, blank=True, null=True)

class Meta:

My forms:
我的表格：
class PhotoForm(forms.Form):
filename = forms.FileField()
fountain_id = forms.IntegerField('fountain')
class Meta:
model = Photos
class FountainForm(ModelForm):
class Meta:
model = Fountains
fields = [

'foun_desc',
'foun_address',
'foun_lat',
'foun_lon'
]
labels = {

'foun_desc': _('description'),
'foun_address': _('street address'),
'foun_lat': _('lat'),
'foun_lon': _('lon')
}
My views:
我的观点：
This is the view to add gallery:
这是添加图库的视图：
def fountain_add(request):
if request.method == 'POST':
form = FountainForm(request.POST)
if form.is_valid():
new_fountain = form.save()
return HttpResponseRedirect(reverse(fountain, args=(new_fountain.pk,)))
else:
form = FountainForm()
return render(request, "app/fountain_add.html", {'form': form})
This is view to redirect to new gallery view:
这是重定向到新图库视图的视图：
def fountain(request, id):
assert isinstance(request, HttpRequest)
fountain = Fountains.objects.get(id=int(id))
context_dict = {'fountain': fountain}
return render(
request,
'app/fountain.html',
context_dict,
context_instance = RequestContext(request)
)
Photo_upload view:
Photo_upload视图：
@login_required
def photo_upload(request, id):
#def photo_upload(request):
fountain = Fountains.objects.get(id=int(id))
if request.method == 'POST':
form = PhotoUploadForm(request.POST, request.FILES)
if form.is_valid():
new_photo = Photos(filename = request.FILES['filename'])
new_photo.save()
return HttpResponse('Image upload succeeded.')
else:
form = PhotoUploadForm()
data = {'form': form}
return render_to_response('app/photo_upload.html', data, context_instance=RequestContext(request))
My templates:
我的模板：
This is template for gallery view that has the photo_upload link:
这是具有photo_upload链接的图库视图的模板：
{% extends "app/layout.html" %}
{% block content %}
<h1>Fountain Details</h1>
<div style="width:600px">
<p>Name: {{ fountain.foun_name }}</p>
<p>Desc: {{ fountain.foun_desc }}</p>
<p>Address: {{ fountain.foun_address }}</p>
<p>Lat: {{ fountain.foun_lat }}</p>
<p>Lon: {{ fountain.foun_lon }}</p>
<p><a href="/photo_upload/{{ fountain.id }}/"}>Upload photos</a></p>
</div>
{% endblock content %}
My template for photo_upload. This has the dropzone.js in it:
我的photo_upload模板。这里面有dropzone.js：
{% extends "app/layout.html" %}
{% block content %}
<h1>Photo Upload</h1>
<p>Fountain: {{ fountain.foun_name }}</p>
{% load staticfiles %}
<link href="{% static 'dropzone/dropzone.css' %}" rel="stylesheet">
<form action="{% url "photo_upload" %}" class="dropzone" id="myDropzone" method="post" enctype="multipart/form-data">
{% csrf_token %}
<div class="fallback">
<p><input name="fountain" type="hidden" /></p>
<p><input name="file" type="file" multiple /></p>
<p><input type="submit" value="Upload" /></p>
</div>
</form>
<script src="{% static 'dropzone/dropzone.js' %}"></script>
<script type="text/javascript">
Dropzone.options.myDropzone = {
autoProcessQueue: false,
paramName: "filename",
addRemoveLinks: true,
//parallelUploads: 1,
init: function () {
var submitButton = document.querySelector("#submit_photos")
myDropzone = this;
submitButton.addEventListener("click", function () {
myDropzone.processQueue();
});
myDropzone.on("complete", function (file) {
myDropzone.removeFile(file);
});
}
};
</script>
<button id="submit_photos">

If you not attaching id , then write view as
如果您没有附加id，则将视图写为
def photo_upload(request, id=None):
OR
要么
"{% url 'photo_upload' id %}" #id if you are attaching /id in url.
Your photo_upload view needs parameter id
