Variables

Variables

As we recall from the previous lesson, a template contains variables, which get replaced with values when the template is evaluated.

Syntax of a variable

A variable looks like this: {{ variable }}.

Variable names consist of any combination of alphanumeric characters and the underscore (_), but they may not start with an underscore.

NOTE: We cannot have spaces or punctuation characters in variable names.

Use a dot (.) to access the attributes of a variable.

How to use variables

We use variables inside the templates by passing any Python object to the render() function.

return render(request,"index.html", context = any_object)

In the example above, index.html is the name of the template and context is the name of the object we are passing.
