Evennia is its own webserver and hosts a default website and browser webclient.
The Evennia website is a Django application that ties in with the MUD database. Since the website
shares this database you could, for example, tell website visitors how many accounts are logged into
the game at the moment, how long the server has been up and any other database information you may
want. During development you can access the website by pointing your browser to
You may also want to set
DEBUG = Truein your settings file for debugging the website. You will then see proper tracebacks in the browser rather than just error codes. Note however that this will leak memory a lot (it stores everything all the time) and is not to be used in production. It’s recommended to only use
DEBUGfor active web development and to turn it off otherwise.
A Django (and thus Evennia) website basically consists of three parts, a
view an associated
template and an
urls.py file. Think of
the view as the Python back-end and the template as the HTML files you are served, optionally filled
with data from the back-end. The urls file is a sort of mapping that tells Django that if a specific
URL is given in the browser, a particular view should be triggered. You are wise to review the
Django documentation for details on how to use these components.
Evennia’s default website is located in
evennia/web/website. In this
folder you’ll find the simple default view as well as subfolders
Customizing the Website¶
You customize your website from your game directory. In the folder
web you’ll find folders
templates_overrides. The first two of those are
populated automatically by Django and used to serve the website. You should not edit anything in
them - the change will be lost. To customize the website you’ll need to copy the file you want to
change from the
web/website/static/ path to the corresponding place under one of _overrides` directories.
Example: To override or modify
evennia/web/website/template/website/index.html you need to
The detailed description on how to customize the website is best described in tutorial form. See the Web Tutorial for more information.
Overloading Django views¶
The Python backend for every HTML page is called a Django view. A view can do all sorts of functions, but the main one is to update variables data that the page can display, like how your out-of-the-box website will display statistics about number of users and database objects.
To re-point a given page to a
view.py of your own, you need to modify
URL pattern is a regular
expression that you need to enter in the address
field of your web browser to get to the page in question. If you put your own URL pattern before
the default ones, your own view will be used instead. The file
urls.py even marks where you should
put your change.
Here’s an example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
# mygame/web/urls.py from django.conf.urls import url, include # default patterns from evennia.web.urls import urlpatterns # our own view to use as a replacement from web.myviews import myview # custom patterns to add patterns = [ # overload the main page view url(r'^', myview, name='mycustomview'), ] urlpatterns = patterns + urlpatterns
Django will always look for a list named
urlpatterns which consists of the results of
calls. It will use the first match it finds in this list. Above, we add a new URL redirect from
the root of the website. It will now our own function
myview from a new module
If our game is found on
http://mygame.com, the regular expression
"^"means we just entered
mygame.comin the address bar. If we had wanted to add a view for
http://mygame.com/awesome, the regular expression would have been
Look at [evennia/web/website/views.py](https://github.com/evennia/evennia/blob/master/evennia/web/we
bsite/views.py#L82) to see the inputs and outputs you must have to define a view. Easiest may be to
copy the default file to
mygame/web to have something to modify and expand on.
Restart the server and reload the page in the browser - the website will now use your custom view.
If there are errors, consider turning on
settings.DEBUG to see the full tracebacks - in debug mode
you will also log all requests in
Evennia comes with a MUD client accessible from a normal web browser. During
development you can try it at
See the Webclient page for more details.
The Django ‘Admin’ Page¶
Django comes with a built-in admin website. This is accessible by clicking the ‘admin’ button from your game website. The admin site allows you to see, edit and create objects in your database from a graphical interface.
The behavior of default Evennia models are controlled by files
admin.py in the Evennia package.
New database models you choose to add yourself (such as in the Web Character View Tutorial) can/will
admin.py files. New models are registered to the admin website by a call of
admin.site.register(model class, admin class) inside an admin.py file. It is an error to attempt
to register a model that has already been registered.
To overload Evennia’s admin files you don’t need to modify Evennia itself. To customize you can call
admin.site.unregister(model class), then follow that with
admin.site.register in one of your own
admin.py files in a new app that you add.
Evennia relies on Django for its web features. For details on expanding your web experience, the
Django documentation or the Django
Book are the main resources to look into. In Django
lingo, the Evennia is a django “project” that consists of Django “applications”. For the sake of web
implementation, the relevant django “applications” in default Evennia are
