How to call python command in html using jinja2?

Question

Flask

I want to call trans command in

app.py html file:

def trans(txt): # функция для вызова
   return txt

index.html:

{{ trans('test') }} // Вызываю функцию, но нечего не происходит

How can such functionality be made?

Answer 1

well, let me read the docks for you https://flask.palletsprojects.com/en/2.0.x/templat...

Answer 2

Well, at least for starters, pass it to the context:

def foo():
    return "foo() called"

Template("{{ foo() }}").render(foo=foo)

On the other hand, the need to call the trans function in the template is not at all clear. Isn't it easier to specify txt right away ? Well, or write the return value to a variable and pass it already.
