Error in engine.py, using python3.9 (posixpath.py) when template_path is None about web-applications-with-fastapi-course HOT 9 CLOSED

A quick workaround would be to call global_init() before any views import.

From ./code/ch8-async-databases/main.py:

from pathlib import Path

import fastapi
import fastapi_chameleon
import uvicorn
from starlette.staticfiles import StaticFiles

from data import db_session

fastapi_chameleon.global_init('templates', auto_reload=True)

from views import account
from views import home
from views import packages

Note the auto_reload=True argument which set to dev_mode variable in the origin call.

This looks really similar to the error I'm getting and I'm going to talk to Michael in office hours today in about 30 minutes.

This line in particular matches an error I'm getting:
File "/home/cristiana/anaconda3/envs/fastapi/lib/python3.9/posixpath.py", line 76, in join a = os.fspath(a)

I also see:

File "/Users/prcutler/workspace/silversaucer/testvenv/lib/python3.9/site-packages/fastapi_chameleon/engine.py", line 71, in response_inner
    if not os.path.exists(os.path.join(template_path, template_file)):
  File "/usr/local/Cellar/[email protected]/3.9.2_1/Frameworks/Python.framework/Versions/3.9/lib/python3.9/posixpath.py", line 76, in join
    a = os.fspath(a)

I have a bug open in my repo at prcutler/silversaucer#317 and if I find an answer, I'll post here as well.

Hello @prcutler , the error seams to be in engine.py (fastapi-chameleon). It is calling os.path.join with a parameter with None (template_path).

I have made a temporary solution in the following function, to be able to run the code.

Yet, I havent figured out where template_path should be declared in order to make this works ;-)

    def response_inner(f):
        nonlocal template_file

        if not template_file:
            # Use the default naming scheme: template_folder/module_name/function_name.pt
            module = f.__module__
            if '.' in module:
                module = module.split('.')[-1]
            view = f.__name__
            template_file = f'{module}/{view}.html'

            if template_path is not None:
                if not os.path.exists(os.path.join(template_path, template_file)):
                    template_file = f'{module}/{view}.pt'
            else:
                template_file = f'{module}/{view}.pt'

This should be fixed as Michael released a new version.

Just run:

pip install git+https://github.com/mikeckennedy/fastapi-chameleon again

I believe not, since I installed the package today.

He released a new version after these bug reports and it did fix it for me. Make sure you're using fastapi_chameleon-0.1.7 and not 0.1.6

See: mikeckennedy/fastapi-chameleon#7

from web-applications-with-fastapi-course.

fastapi-chameleon-0.1.7 fixed it for me too.

Thanks @prcutler and @mikeckennedy

Cool ! Thank you !
