I think I hav a problem at request.POST['title']

MultiValueDictKeyError at /blog/add/post/"'title'"Request Method: GETRequest URL: http://119.81.247.69:8000/blog/add/post/Django Version: 1.8.2Exception Type: MultiValueDictKeyErrorException Value:
"'title'"Exception Location: /usr/local/lib/python2.7/dist- packages/django/utils/datastructures.py in getitem, line 322Python Executable: /usr/bin/pythonPython Version: 2.7.3

views.py

def add_post(request):entry_title = request.POST["title"]return HttpResponse('Hello %s' % entry_title)

write.html

<form method="POST" action="/blog/add/post/">
<p><label for "title">Title</label><input type="text" id="title" name="title" value="" />
</p>
<p><label for 'category'>Category</label><select id="category" name="category"></select>
</p>
<p><label for 'tags'>Tags</label><input type="text" id="tags" value="" />
</p>
<p><textarea id="content" name="content"></textarea>
</p>
<p><input type="submit" value="Write" />
</p>

Change:

def add_post(request):entry_title = request.POST["title"]return HttpResponse('Hello %s' % entry_title)

to:

def add_post(request):entry_title = request.POST.get("title", "Guest (or whatever)")return HttpResponse('Hello %s' % entry_title)

and it won't throw a KeyError, but you should look at using Django's forms rather than pulling values directly from the POST data.

Alternatively, you can keep your existing code and simply check for the exception:

def add_post(request):try:entry_title = request.POST["title"]except KeyError:entry_title = "Guest"return HttpResponse('Hello %s' % entry_title)

but this is what .get() does internally already.
