i am new in javascript and its relative libraries and framework,i am just struggling to give notification when i have successfully complete any form submission.I have a project which is developed by Django and in this project i have an image upload form.Here is the views.py of the image upload form...
from django.shortcuts import render_to_response,RequestContext
from photo.models import Photo
from django.contrib.auth.decorators import login_required
from myprofile.forms import DocumentForm
from django.contrib.auth import authenticate, login, logout, REDIRECT_FIELD_NAME
def UserImageUpload(request):
if request.method == 'POST':
form = DocumentForm(request.POST,request.FILES)
if form.is_valid():
newdoc = Photo(photo = request.FILES['photo'],user = request.user)
newdoc.save()
else:
form = DocumentForm()
uploaded_image = Photo.objects.all()
return render_to_response('myprofile/user_image_upload.html',{'uploaded_image':uploaded_image,'form':form},context_instance = RequestContext(request))
and this is the forms.py...
from django import forms
class DocumentForm(forms.Form):
photo = forms.ImageField(
label='Select a file'
)
and this the template.. (upload_image.html)
{% extends 'base.html'%}
{% block title%}User Image Upload {% endblock %}
{%block content%}
<div class="container" style="margin-top:5%">
<div class="col-md-4 col-md-offset-4">
<div class="well">
<form action="" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.photo.label_tag }} {{ form.photo.help_text }}</p>
<p>
{{ form.photo.errors }}
{{ form.photo }}
</p>
<p><input type="submit" value="Upload" class="btn btn-success" /></p>
</form>
</div>
</div>
</div>
{%endblock%}
now i want to give notification to user after he succesfully upload an image, or you can say, after the successful upload form submission . How can i do this with javascript/jquery?
Normally, you'd want to redirect after a successful form submission, ie:
if form.is_valid():
newdoc = Photo(photo = request.FILES['photo'],user = request.user)
newdoc.save()
return http.HttpResponseRedirect('....')
if you're doing ajax-y form submission, you'll need to return something that the ajax call understands as success, eg:
if form.is_valid():
newdoc = Photo(photo = request.FILES['photo'],user = request.user)
newdoc.save()
response = http.HttpResponse(json.dumps({"status": 'ok'}))
response["Content-Type"] = 'application/json'
return response
