Why Django Admin Is Not Working On Tommy?

Why django admin is not working on Tommy?

 

Thanks in advance!

[Bailey]

Is the css not being shown properly?

 

Also, may I have a link to the admin page please.

[formigol]

Yes, it seems that the css is not working. Now the site is very simple, basically the same as the djangotest example that i found here: https://www.helionet.org/index/topic/27585-django-on-tommy/

 

If I try to install some of my apps the admin page stops working at all.

 

This is the link to my admin page: http://www.colouredsweat.heliohost.org/colswe/admin/login/?next=/colswe/admin/

 

Thanks a lot for your help!

[Bailey]

Okay, I had this very problem.

 

Basically you have to convert your static files, CSS etc. into a folder called "static" using command line.

 

Ill just find the link to everything which explain more.

[Bailey]

Add this line to your apps "django.contrib.staticfiles" as this provides a convenience management command for gathering static files in a single directory so you can serve them easily.

Set the

STATIC_ROOT

setting in the config file (I am unsure where this goes due to it being a while however it is in the file with the main configs) to the directory from which youd like to serve these files, for example:

STATIC_ROOT = "C:/path/to/website/example.com/static/"

Run the collectstatic management command:

$ python manage.py collectstatic

This will copy all files from your static folders, such as the admin page, into the static directory (example.com/static).

 

Now upload.

[Bailey]

Dont forget to add the static directory:

RewriteEngine On
RewriteBase /
RewriteRule ^(static/.*)$ - [L]

to your .htaccess file that contains your .wsgi etc.

Hello and happy new year!

 

First: Thanks a lot for your help!

 

I'm still having a lot of problems and I'm still not able to deploy my apps on tommy... I'm missing something... when I try to deploy a simple djangotest app (following the instructions online) more or less it works (the css problem that you already told me how to solve) but when I try to install an application that I developed on my PC everything goes crazy and nothing works. I get the following errors:

Do you have any suggestions? The problem is that I really don't understand what's wrong.

Thanks in advance!

[Bailey]

Ah okay, I'm unsure on these exact errors because I abandoned Django. It looks like the file "500.shtml" is missing from "/public_html/" but all you should need to do is create an empty file.

 

However, the "dispatch.wsgi" file seems to be causing more issues. I would google the exact errors you are having (just copy and paste) as other people would have had the same problem. This should bring up a fix after reading maybe one or two posts about it.

 

Sorry I couldn't be of more use.

The best debugging advice for a situation like this is start small and simple. Make sure it works, and then make some small changes and make sure it works again. Unless your home pc is running the exact same os and the exact same versions of everything there are going to be differences when you deploy it.

[formigol]

Ok. I will write everything I have done until now following a tutorial structure; maybe it will be useful  for future Django users on Heliohost:

 

1. I started the project from scratch using the cookiecutter.

2. Than I uncommented the following commented lines in the project_name/urls.py. That generate an admin log-in page at the URL http://www.your_name.heliohost.org/project_name/admin

from django.conf.urls import url
#from django.contrib import admin

urlpatterns = [
    #url(r'^admin/', admin.site.urls),
]

3. At this point I visited the page and I noticed that the css was not working (see the discussion before)

 

4. I collected all the static files of my project located on my personal computer. To do that:

 

--> first I added the following two lines in my project_name/settings.py file

STATIC_URL = '/static/' # url that django uses to find the static files while the server is running
STATIC_ROOT = '/path/to/my/project/folder/static' #url that says to django were to collect all the statics (on the local host)

--> than in the terminal I typed the following command to collect all the static in the URL_ROOT.

./manage.py collectstatics

--> I made a .tar file and deployed everything on the server.

 

4. The next step is to create a superuser to test the admin application

 and there is were the problems are coming out.

 

--> I created the superuser on my local host. (from now on after every change on my local host I deployed the new version on the server trough filemanager)

./manage.py createsuperuser

Everything worked on the server until I tried to login with my new super user. At this point django show me an error page saying that: Django Attempt to write a read-only database.

I tried to change the permissions of the database (the file called db.sqlite3) to 777 and the django error trasformed into: unable to open database file

What do you suggest to solve the problem? Maybe I should use a database provided by heliohost and not the one created on my local host?

 

Thanks in advance for your help!

[Krydos]

We strongly recommend using mysql, not sqlite. It's much easier to get working.
