Also having your models would be helpful.

application not recognized as URL namespace

[Axel Rau]

In my root url, I have:

url(r'^authentication/', include('authentication.urls')),

in authentication/urls.py, I have no app_name declared.

In a module in authentication, I have

from django.core.urlresolvers import reverse

from django.apps import apps
print('authentication installed? ' + 
str(apps.is_installed('authentication')))

reverse('authentication:password_change',urlconf='authentication.urls')
 
and receive
django.core.urlresolvers.NoReverseMatch: 'authentication' is not a 
registered namespace
while the above debug print gives
authentication installed? True 

What am I doing wrong here?

Please advice,
Axel

Re: application not recognized as URL namespace

[knbk]

Hi Axel,

An installed application and a registered URL namespace are two distinct 
concepts. A URL namespace can only be defined by setting the app_name 
attribute in your urlconf. In this case, you haven't set a URL namespace 
for your authentication app, so your urls are not namespaced.

Also, the urlconf parameter to reverse() should point to the root urlconf, 
not to the urlconf in which your current url is defined. Since it defaults 
to the root urlconf defined in your project, it's easiest to omit it in 
most cases. If you don't, and use 'authentication.urls' as your root 
urlconf, the generated url will miss the 'authentication/' part of your 
url. 

To reverse the password_change url, simply use this:

reverse('password_change')

OK. (I misunderstood the 1.9 docu as this would be required only with instance 
namespaces).

I understand.

Making both changes gives:
django.core.urlresolvers.NoReverseMatch: Reverse for 'password_change' 
with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

I then tried to reference the views directly instead of strings:

from . import views
reverse(views.password_change),

with views.py containing:

class PasswordChangeView(LoginRequiredMixin, AuthDecoratorsMixin, 
WithCurrentSiteMixin, FormView):
...

password_change = PasswordChangeView.as_view()

and got;

django.core.urlresolvers.NoReverseMatch: Reverse for 
'authentication.views.PasswordChangeView' with arguments '()' and keyword 
arguments '{}' not found. 0 pattern(s) tried: []

I thought you didn't have an app_name, but you do have one. In that case, 
the only problem was that you passed the wrong urlconf to reverse(). You 
should be able to reverse the url with:

reverse('authentication:password_change')

I did not try this combination, but it works!  Thanks!

One last question:

Changing this to an instance namespace would just require in urls:

url(r'^auth/', include('authentication.urls', namespace='auth')),

and where I reverse:

reverse(’auth:password_change’)

right?

But this again gives:

django.core.urlresolvers.NoReverseMatch: 'auth' is not a registered namespace

[Axel Rau]

I see my error: ’auth’ is already an appname (django.contrib.auth).
Using ’accnt’ works perfectly!

Thanks, again, Axel

 Hi Axel,
 
 An installed application and a registered URL namespace are two distinct 
 concepts. A URL namespace can only be defined by setting the app_name 
 attribute in your urlconf. In this case, you haven’t set a URL namespace 
 for your authentication app, so your urls are not namespaced.
>>> OK. (I misunderstood the 1.9 docu as this would be required only with 
>>> instance namespaces).
 
 Also, the urlconf parameter to reverse() should point to the root urlconf, 
 not to the urlconf in which your current url is defined. Since it defaults 
 to the root urlconf defined in your project, it's easiest to omit it in 
 most cases. If you don’t, and use 'authentication.urls' as your root 
 urlconf, the generated url will miss the 'authentication/' part of your 
 url.
>>> I understand.
  
 
 To reverse the password_change url, simply use this:

Re: calling html file from within javascript

[Gary Roach]

Hi Gergely

I agree that document.write is a bad idea. Freezing in this case may be 
a poor choice of words. I was trying to convey that the code executes OK 
until it gets to the .write line and hangs up. It never completes the 
.write line.


As for purpose. Main.html is a template contains the permanent headers 
and footers for the site with the body consisting of an iframe 
containing a {% block content %} {% endblock %} statement. When each 
button is pushed, all buttons are disabled and the .html template file 
associated  with the particular button is used to fill the block 
content. This worked when I didn't use javascript to call welcome.html. 
But I can't seem to figure out how to serve up the file with javascript. 
I really don't want to change the general method. I have never liked web 
sites that allow users to hit the same button twice or hit more than one 
button in mid load. I know that one can build buttons using link but 
this seemed more straight forward to me. ie have the  button call a 
javescript function and let the function do all of the heavy lifting.


I've had many years of various levels of programming and system 
maintenance but have been retired since 1998 and am pretty rusty. In 
addition, the technology has shifted significantly since. So for all 
practical purposes I'm an nooby and am trying to master python, html, 
javascript and django all at the same time. Learning by doing I guess.


So the bottom line is that I need a code snippet to put under case b1 
that will insert welcome.html into the block statement in main.html.


Any help will be sincerely appreciated.

Gary R.

As you see, using document.write is a very bad idea. However, freezing 
is not mentioned in that document. What does freezing mean in this 
case? Are you sure it's this code that gets executed and freezes?


Also, what exactly do you want to achieve?

Best,
Gergely
