[Py4web 1.20210906.1 / Ombott] Request context not initialized.

Hi,

I upgraded to the latest py4web version 1.20210906.1 with ombott.

While the app was working with the previous version with bottle, I had some issues.

One of them is to handle the header responses. I try to get a specific JSON output and some CORS headers. Here is a sample controller:

@action('api/beid', method=['GET'])

def beid():

import json, bottle

from base64 import b64encode

from .beid import scan_readers, read_infos, triggered_decorator

from time import sleep

r = scan_readers()[0]

infos_json = {}

response = bottle.response

response.headers['Content-Type'] = 'application/json;charset=UTF-8'

response.headers['Access-Control-Allow-Origin'] = '*'

response.headers['Access-Control-Allow-Methods'] = 'GET, POST, PUT, OPTIONS'

response.headers['Access-Control-Allow-Headers'] = 'Origin, Accept, Content-Type, X-Requested-With, X-CSRF-Token'

try:

# sleep(2)

infos = read_infos(r, read_photo=True)

infos['photo'] = b64encode(infos['photo']).decode('utf8')

except Exception as e:

infos = { 'results': 'cannot read card', 'erreur': e.args}

infos_json = json.dumps(infos)

return infos_json

I now get the following exception:

Traceback (most recent call last): File "/home/mamisoa16/code/py4web/lib/python3.8/site-packages/py4web/core.py", line 901, in wrapper ret = func(*func_args, **func_kwargs) File "/home/mamisoa16/code/py4web/apps/myapp/rest.py", line 60, in beid response.headers['Content-Type'] = 'application/json;charset=UTF-8' File "/home/mamisoa16/code/py4web/bin/bottle.py", line 1537, in headers hdict.dict = self._headers File "/home/mamisoa16/code/py4web/bin/bottle.py", line 1671, in fget raise RuntimeError("Request context not initialized.") RuntimeError: Request context not initialized.

What is odd is that sometimes I do GET the request, but without the headers.

Any ideas?

Ok I got it working by removing the bottle import...
