Hello,

The messages framework might be helpful here.

from django.contrib import messages
messages.add_message(request, messages.INFO, 'Password was changed')
return logout_then_login(request, login_url='/login/')

{% for message in messages %}
{{ message }}
{% endfor %}

Now I try change this part of code in views.py

#request.user.set_password(form.cleaned_data['password2'])
#request.user.save()
#return render(request, 
'registration/change_password_success.html', {'user': request.user})

On 

from django.contrib.auth import logout,login,authenticate,*password_change*
.
.
.

password_change(request,'registration/change_password_success.html',
post_change_redirect=None,
password_change_form=FormularzPasswordChange, 
current_app=None, extra_context=None)

urls.py

This change

#url(r'^password_change/$', views.password_change_dom, 
name='change_password'),


On this

url(r'^password_change/$', 'django.contrib.auth.views.change_password'),

Re: The view didn't return an HttpResponse object.

[Babatunde Akinyanmi]

Its possible that when you refresh the form and the POST request gets
submitted, the form doesn't pass the form.is_valid() if conditional.
In your code, you didn't make any provision for when the form fails
the is_valid() test and from your code, execution stops once
is_valid() returns False so I **guess** that's where the problem lies.

Try re-rendering the submitted form if is_valid is False or doing a redirect.

The form is not valid; check the data you are submitting and the form
definition to see why. The invalid form object itself will specify why
it is invalid, see the docs:

https://docs.djangoproject.com/en/1.4/topics/forms/#using-a-form-in-a-view
https://docs.djangoproject.com/en/1.4/ref/forms/api/#using-forms-to-validate-data

Thanks, it works and now gives the error message, can you please tell
me that why the input values are not saved in the database and it
gives only the error message. Point me where i am wrong.

If the request method is POST, but the form is not valid, then no
response is returned. You must return a response from every code path.

The view didn't return an HttpResponse object.

[Satinderpal Singh]

I made a model form and a view which accepts input as a form and
display it in the html format. As when i refresh the html page or try
to fill another entry in the form, it gives the following error:

The view Automation.report.views.chemical_analysis didn't return an
HttpResponse object.

Here is the views that creates this problem:
def chemical_analysis(request):
if request.method=='POST':
form = chem_analysisForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
form.save()
chem = chem_analysis.objects.all()
#return HttpResponseRedirect(chem)
return 
render_to_response('report/chemical_analysis.html',
{'chem': chem,},context_instance=RequestContext(request))

else:
form = chem_analysisForm()
return render_to_response('report/report.html', 
{"form":form},
context_instance=RequestContext(request))

Any help regarding this will be highly appreciated.

[Snip snip with binary scissors]

Problem is that there is two problem points:

Your view doesn't have "default path" so
IF request.method is POST and IF form.is_valid is FALSE your code 
doesn't return anything.


This means that your view will return something only if request.method 
is not POST (return render_to_response(...) is called) or if 
request.method is POST and form.is_valid() is true (return 
HttpResponseRedirect(..) is called)


Simplest way to fix it is to indent last "return render_to_response..." 
one level outer (same level as if request.method == 'POST' and last 
else) making it to be executed if request.method is not POST or if 
form.is_valid() is false.


In short form:

def studentid(request):
if request.method == 'POST'
form = Student_loginForm(request.POST)
if form.is_valid():
return HttpResponseRedirect(...)
else:
form = Student_loginForm()
return render_to_response('add_record/studentid.html', ...)

Re: view didn't return an HttpResponse object....plz help

[Jani Tiainen]

It doesn't ever work since you should rerender form with current data 
and errors if form.valid() returns false.


Currently your logic doesn't return _nothing_ if form.valid() is false

def studentid(request):
if request.method == 'POST':
form = Student_loginForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
rollno = cd['rollno']
return 
HttpResponseRedirect(reverse('record_system.views.search' , args=(rollno)))

# No else here, nothing is rendered!

else:
# This else is for if request.method == POST
form = Student_loginForm()
return render_to_response('add_record/studentid.html', 
context_instance=RequestContext(request))



I suggest that you put last return one indent level to left so it will 
always render either errored form or in case method was not POST empty form.

You get the error because your form didn't validate in the first

Print out form.errors it will contain dictionary about fields and errors 
in particular field.


You get the error because your form didn't validate in the first place 
so either you have bad data, are missing required data or something else 
in validation fails. form.errors will reveal that.

There is no HttpResponse object returned if the form is *not* valid. You

I would have thought that it was you refering to the undefined

cd = form.cleaned_data
rollno = cd[rollno]
rollno = request.POST.get(rollno)

Should it not read:

Re: view didn't return an HttpResponse object....plz help

[dizzydoc]

The only condition where this view wont return an HTTPResponse is when 
request.method == 'POST' is True and form.is_valid() is False. 

In this condition the outer if condtion would complete execution and exit 
out since inner if condition is False and wont enter inner if condition.

I think you should move out the return statement from the else loop.

Well, the error message is giving you a very big clue. When you see
that, look for all the ways that you are exiting that function. In this
case, what happens when no exception is raised?

At a guess, you have added the wrong indentation on the last line.

Regards,
Malcolm

This return statement is indented to be inside the except clause. If  
no exception is raised, the view doesn't return anything...

The view didn't return an HttpResponse object.

[oops]

def OrderPlacedView(request):
form = OrderPlaceForm()
try:
print "try"
print request.POST
#brand = BrandName.objects.get(pk=request.POST['brand'])
except:
print"nothing"
return render_to_response('inventory/orderprocess.html',
{'form':form})

above is my view code when a try to call this view its give and error
"The view  didn't return an HttpResponse object."

i have similar type of view which works fine whats the problem with
this ..

Ok thank you! I've taken care of the superfluous code and thought it
was something silly I was missing. Thanks!

Just as a side-note, these two are a bit redundant.  I'd suggest
either

  if 'avatarkey' not in request.GET or
len(request.GET['avatarkey'] != 36:
raise Http404

or even just

  if len(request.GET.get('avatarkey', '') != 36:
raise Http404

because if the key is missing, your default's length is certainly
not 36 either :)

Well, you're not doing a "return render_to_response".  If that's
merely a code transcription omission, read on...otherwise, it
would 'splain why it's not returning what you think it should be
returning. :)

I'm slightly confused why you're passing an empty dict() into
your render_to_response() call.  Seems superfluous to me.

Two other questions:

Which version of Django are you using?

What do you mean by "does...not work"?

from django.http import HttpResponse, Http404
