render_template hangs when using microdot_asyncio about microdot HOT 5 OPEN

BTW I'm relatively new to asyncio but have used microdot successfully before

from microdot.

Apologies, it isn't render_template that is hanging it is the return of the template. I put some print statements around the render_template and it is working fine. I needed to make the function after the @route an async.

@app.route('/')
async def index(req):

I don't really uderstand why, but suspect this is my lack of understanding of async. Happy to close if my thought is correct

@Odud: Ah, okay, I do see what the problem is now. In MicroPython async functions are really generators. The render_template() function returns a generator as well. Microdot is confused because a non-async function is returning something that looks like what an async function would return. I need to find a way to distinguish the return value of calling an async function from a generator returned by a non-async function, which actually look the same.

In the meantime your solution is fine, just make sure any functions that use render_template() are defined as async functions. I'll investigate to see if I can figure out how to make non-async functions work as well.
