The goal of this project is to provide a way to pass variables to Django templates, in a single container, and to be able to access them in a simple way.
A container ensures that you always know what variables are generally available in the template to differentiate them from the variables passed to the context in the view.
Define in the context_processors.py file the variables that will be available in the template context.
from django.conf import settings
def get_window_variables(self):
"""A dictionary of variables that will be available in the window object."""
return {
"user": {
"id": self.request.user.id,
},
"support_email": "[email protected]",
}
def get_global_variables(self):
"""A dictionary of variables that will be available in the template context."""
return {
"DEBUG": settings.DEBUG,
"user": {
"id": self.request.user.id,
}
}Then, in the base.html file, you can access the variables like this:
# base.html
<!-- access directly in the template -->
{{ template_vars.user.id }}
{{ template_vars.DEBUG }}
<!-- access in the window object -->
<script>
console.log(window.appVars)
// > {
// > user: { id: 1 },
// > support_email: "[email protected]"
// > }
console.log(window.appVars.user.id)
// > 1
</script>
