render_block breaks django permission with htmx rendered template?

[gmaz-tauruz]

In the rendered template via htmx ajax call, { % perms.foo.change_bar %} will not work, and {{ perms }} returns empty?

[gmaz-tauruz]

This happens only when using render_block_to_string(), otherwise ok if i use TemplateResponse()

Can you provide a more complete example of the issue you're running into? What is perms? What are the results from render_block_to_string vs TemplateResponse?

Ok, I will try to re-create the case. I did not pursue it coz i read somewhere (i think in htmx essay) that render_block somewhat discourages the use of django permissions in the template, and in favor of checking the user permissions rather in views.

If you have a reference to the article that would be helpful too. In general handling any sort of business logic in templates is usually a bad idea though.

Here's a link (https://github.com/gmaz-tauruz/render-block-testing) of the stripped down version of the app I tried to re-create. Though, I wasn't able to re-create the different results with using render_block_to_string() vs TemplateResponse() - they both produced the same result where {{ perms }} ( https://docs.djangoproject.com/en/5.0/topics/auth/default/#permissions-and-authorization) seems not recognized.

I'm thinking this issue is happening because render_block_to_string doesn't load the context_processors which is where perms (or user) comes from. It's possible to add it to the context yourself when using render_block_to_string, it's just a bit clunky. I'm not sure if this is the actual problem though, or if there's an easy fix vs this is an architectural decision?
