Re: More standard template filters
A similar ticket from 6 years ago (with some more filters) was closed as a
wontfix: https://code.djangoproject.com/ticket/22162
Unless there was a change in the phylosiphy, I don’t think this will be
accepted either (I don’t have an opinion about whether it shouldbe, though
leaning towards not).
As a side note, I think the `in` operator fills the function of the
`contains` filter:
"testing" in myvar

Django Template Language has a lot of legacy that prevents this from
happening, afaiu it would not be possible to move to it.
It's not hard to move your templates (asides from those extending
external packages like the admin) to Jinja2, since the syntax is very
similar and you can pop a Jinja2 backend in your TEMPLATES.

It's almost like we need a syntax for calling methods with an argument,
just like we can with filters.
For example (bring on the sheds for bikes!)
{{ myvar.startswith<"teststring" }}

Alternatively, I recall some time in the past I may have written a
"strings" template filter library simply to provide string methods as
filters...

Re: More standard template filters
There are already filters which works on advance logic. for example :-
'join'. So, is it not good to add filter for startswith, endswith and
contains as well?

For "legacy" read "philosophical choices" :)
