Question

After i submit my form using GET method and then refresh the page the data get resubmitted
i am using javascript for form validation

my views are:

def show(request,post_id):
    try:
        p = post.objects.get(pk=post_id)
        c = comment.objects.filter(blog_id=p)
        if 'cbox' in request.GET:
            c = comment(text=request.GET['cbox'],name=request.GET['cname'],blog=p)
            c.save()
        c_list = comment.objects.filter(blog_id=p)   
    except  post.DoesNotExist:
        raise Http404
    return render_to_response('show.html',{'post':p,'c_list':c_list})

my form is:

<form  name="comment" action="" method="get" onsubmit="return validateForm()">
    <input id="carea"  type="text" placeholder="leave a comment" name="cbox" >
    <input id="cb"  type="submit"  value="Post" />
    <input id="cn"  type="text"  placeholder="Name" name="cname">
</form>

i want that when i refresh my page my data should not get resubmited

If you really insist on using GET to submit which practically is not a good method. You should do a request redirect using HttpResponseRedirect from the server side which will remove the query string from the url . This way it wouldn’t resumit the form.

def show(request,post_id):
    try:
        p = post.objects.get(pk=post_id)
        c = comment.objects.filter(blog_id=p)
        if 'cbox' in request.GET:
            c = comment(text=request.GET['cbox'],name=request.GET['cname'],blog=p)
            c.save()
            #Do a redirect here 
            return HttpResponseRedirect("URL of the page you would like to redirect")
        c_list = comment.objects.filter(blog_id=p)   
    except  post.DoesNotExist:
        raise Http404
    return render_to_response('show.html',{'post':p,'c_list':c_list})
