Working environments is made even better by defining some variables that are only active in that specific environment.
Set Variables
navigate to $VIRTUAL_ENV/bin/postactivate
{% highlight bash %} export FIRST_NAME="Sam" export LAST_NAME="Gutentag" {% endhighlight %}
Unset Variables
navigate to $VIRTUAL_ENV/bin/predeactivate
{% highlight bash %} unset FIRST_NAME unset LAST_NAME {% endhighlight %}
Verify Variables are being Set and Unset correctly
In this example, use the command $ printenv | grep _NAME
- Before activating the virtualenv, it should return no results
- After activating the virtualenv, it should return our variables
- After deactivating the virtualenv, it should return no results
