Maybe it's a little bit stupid question, but I didn't find an answer. Is there any way to use increased/decreased variables in django templates?
e.g.{{ some_variable + 1 }}

POST form (your current approach) This answer is perfect and I learned a great deal!
This template tag allows you to increment a variable within a template. This avoids the need of having to use the add filter and the syntax is quite intuitive. ''' usage {% ++ <var_name> %} For example {% ++ a %} ''' def increment_var(parser, token): parts = token.
We can set the value of a variable in the Django template using with tag. This will output the below content. One downside of this approach is that we have to write the lines where we are accessing the variable inside with and endwith block. Using with is useful when using a costly variable multiple times.
Variable names consist of any combination of alphanumeric characters and the underscore ( "_" ) but may not start with an underscore, and may not be a number.
There's a built-in add filter:
{{ some_variable|add:"1" }}
