Re: ViewDoesNotExist at /admin/

[Russell Keith-Magee]

Hi Daniel,

The error you've described isn't related to the admin site at all -- the problem lies somewhere else in your codebase.

django.views.generic.list_detail.object_list was one of the old function-based generic views; it was deprecated in Django 1.3, and removed entirely in Django 1.5. You have code that is using (or at least referencing) this old view.

Without knowing what else is in your project, or seeing the full stack trace, it's impossible to say exactly what is causing this error. It's possible the problem is being caused by a third party Django app that you've included in your project.

Yours,

Hi all,

I've spent lot of time trying to figure out what is going on there, but my admin site is still not working.

I just followed the Django tutorial to create an app named polls. But I have a customized template_dir which is used by my previous app.

All the configurations to activate admin site are the same from official tutorial. But when I am trying to access the admin site: http://127.0.0.1:8000/admin/

I got the exceptions below:

Not like most of the similar issues from google. I found there is something wrong with the 'django.views.generic.list_detail does not exist'?? 

I am new to Django, could you please give me some hints to solve this?

Thanks a lot

[Russell Keith-Magee]

Hi Gabriele,

The answer is the same as before. You have some code that is referencing django.views.generic.list_detail.object_list. As of Django 1.5, this view no longer exists. You need to find out what code is referencing this view, and update it.

The problem code might be your own code, or it might be a third party app. You'll need to check all the apps in INSTALLED_APPS to see if there are any reported problems with Django 1.5 compatibility.

Yours,

Russ Magee %-)

Hi Russel,

thanks for your answer. I found the problem. Is related to Photologue.
Do you have any information about it ?

Thank you very much

Gabri

[Russell Keith-Magee]

Hi Gabriele,

Unfortunately, no. I'm aware of the name, but  I haven't used Photologue myself, so I don't really know anything about it. You'll need to check the project pages and support lists for Photologue itself.

Yours,

Hi Russel,

No problem, I found some information on-line and I fixed. now it works fine.
I had to modify urls.py in photologue.

Hi Gabriele,

That's not an error I immediately recognise the cause of; however, from the stack trace, it suggests that something in FeinCMS has overridden something in admin, but has done so in a way that isn't compatible with Django itself. Unfortunately, I can't tell if this is a fault in FeinCMS, or a fault in your configuration of FeinCMS - again, you'll need to consult the support mailing lists for that product for better advice.

Hi Russel,

thank you for your e-mail !!!
I thought that something was connected with MPTT or FeinCMS... I'll try to work out !
What I really don't understand why so many problem when you in deployment ??? In local everything was super fine !!!

I wil consult FeinCMS forum.

If you're having "deployment only" problems, this points to a problem with the way your development process is organised. These sorts of problems only emerge because your development environment is fundamentally different to your production environment -- for example, different versions of software, different paths. If you make good use of virtualenv to isolate your project, and use requirements files to ensure version compatibility, you should be able to minimise this sort of problem.

I think I found the problem...maybe...

I running my app in the same hosting of another app ... (sorry for my english..is not my first language... I'm italian...)

I have

-- first app
-- feincms
-- other module
-- ...
--second app
-- -- feincms
-- -- other module

Maybe my second-app is using feincms of the first app which is different version.
I think this because I got this error :

No module named filterspecs
/home/alessandrocambogia/feincms/admin/filterspecs.py in <module>, line 7

where alessandrocambogia is the first-app.

I need to have 
/home/alessandrocambogia/gabryandjenny/feincms

where gabryandjenny  is the second-app

but actually I don't know how to change the path... Is my first experience in Django.
Can you help in this ???? Please ??? 
Thank you in advance.

If you are not using virtualenv and pip to manage each of these installations you will likely find it useful to do so. It should eliminate worries about conflicts between version sets.

[Cal Leeming [Simplicity Media Ltd]]

Hello,

Perhaps try installing a completely new/fresh dev environment in a vmware/virtualbox instance, and attempt to get it working from there, that will at least help you narrow this problem down locally instead of poking around at production. Also try and make sure you install the same OS/release as what you are trying to deploy in production. You should also use virtualenv/virtualenvwrapper to help reduce the chance of library/dependency conflict.

Also heads up - realistically the mailing lists are here to point you in the right direction, but it's up to you to do as much of the work as possible. If you come up against a problem, 99% of the time Google will already have the answer. Some great examples of how to use Google accurately can be found at https://code.djangoproject.com/wiki/UsingTheMailingList .

If you're not sure how to use any of the things mentioned, then here are some good starting points for learning;

http://gettingstartedwithdjango.com/ - Django learning

http://learnpythonthehardway.org/book/next.html - Python learning

http://virtualenvwrapper.readthedocs.org/en/latest/

Hope this helps, and remember to update this thread once you figure out the answer so others can find it in the future.

Cal
