url_for support in templates?

[itcld]

Anyone know how to get url_for working in minijinja to generate links to the app, using Actix Web?

Actually I'm new to Rust itself (coming from C# and Python) and haven't been able to figure this out for any of the other Rust templating engines either (Tera, Askama). Actix Web does have a url_for on HttpRequest, but not sure what I need to do to integrate it with minijinja, or if someone has done it.

actix-web makes this incredibly easy because the request object is cheaply clonable and can be stashed into a thread local. This means you can put it there before rendering, and then fetch that object back in a url_for function you can add to the template. I added an example that shows this: https://github.com/mitsuhiko/minijinja/blob/main/examples/actix-web-demo/src/main.rs

@step21 does axum have an API to generate URLs?

[step21]

uhm, probably, but I am still learning it, so not sure. Maybe this? https://docs.rs/axum/latest/axum/extract/struct.Query.html#impl-Clone-for-Query%3CT%3E

I was unable to find an API that generates routes. This issue implies it's not possible: tokio-rs/axum#1947

[step21]

thanks. do you maybe have an alternative idea for just making sure that links have the correct domain etc? F.e. in some of my cases I mainly use it so that files are found both in dev and in prod.
F.e.

<script src="{{ url_for('static', filename='static/js/string.min.js') }}"></script>

[mitsuhiko]

I'm not sure if axum has that information either.

I'm using rocket but cannot find something equivalent, any hints?

[mitsuhiko]

I think you should ask this question in the rocket repo. I'm not sure if rocket supports dynamic route generation as the documented way (uri!) involves code generation.

@mitsuhiko using static routes for now, thanks for the quick response!
