<h1>Handbook Troggle installing Django</h1>
<p>When first installing Django, the first thing to test is that Django itself is OK. So run this command, and this is the output you should see.
<pre>
$ django-admin
Type 'django-admin help <subcommand>' for help on a specific subcommand.
Available subcommands:
<font color="red">[django]</font>
check
compilemessages
createcachetable
dbshell
diffsettings
dumpdata
flush
inspectdb
loaddata
makemessages
makemigrations
migrate
runserver
sendtestemail
shell
showmigrations
sqlflush
sqlmigrate
sqlsequencereset
squashmigrations
startapp
startproject
test
testserver
</pre>
<font color="red"><pre>
Note that only Django core commands are listed as settings are not
properly configured (error: Requested setting INSTALLED_APPS, but
settings are not configured. You must either define the environment
variable DJANGO_SETTINGS_MODULE or call settings.configure() before
accessing settings.).

All the data of all kinds is stored in files. When troggle starts up it imports that data from the files. There are other scripts doing useful things (folk, wallets) and these too get their data from files.
<p>There is never any need to back up or archive the database as it is rebuilt from files. Rebuilding troggle and re-importing all the data on the server takes about 10 minutes (as of May 2021).

<h1>Troggle - software development laptop</h1>
<img src="https://www.python.org/favicon.ico" width=64 hspace="20" align="right" alt='python logo'>
<h2>Software development machine</h2>
<p>For troggle itself, you need a linux machine. We all use Debian or Debian-derived machines (Debian itself, Ubuntu, Xubuntu etc.) but other forms of linux may work. Running Debian or Ubuntu under WSL on Windows 10 works fine.
<p>If you want to work on the troggle source code and be able to commit to the server git repo,
your account will need to be added to the troggle project members list. Contact wookey at wookware dot org to get this set up.
<h3>Prerequisites</h3>
<p>You need to already know really quite a lot about what troggle does, and how it is used in practice. Also you will have installed quite a lot of the software such as tunnel, therion, survex etc. as documented in <a href="../computing/yourlaptop.html">your laptop configuration</a>. In particular read the information there about VS code and git.

<p>The public server uses a <a href="https://mariadb.org/about/">MariaDB SQL database</a> and development is usually done using a single-user <a href="https://sqlite.org/about.html">sqlite database</a> which is a standard Django option.
<p>
You will find it very, very useful to see what is going on if you look directly at the data in the database (just a single file in the sqlite case) and browse the data in the tables. This is vital when doing Django migrations between Django versions. A light-weight, simple db browser is <a href="https://sqlitebrowser.org/">DB Browser for SQLite</a>. Connecting directly the the MariaDB database with a control panel or <a href="https://www.mysql.com/products/workbench/">workbench</a> gives even more tools and documentation capabilities.
