Grid pagination 404 when url_prefix set

[sh-active]

py4web==1.20250330.2

py4web setup apps # install showcase
py4web run apps --port 9765 --url_prefix=/test

Open http://127.0.0.1:9765/test/showcase/example_html_grid/select

Click page number button at bottom e.g. "1" of table gives a 404 Not Found error as the link contains the url_prefix twice:-

http://127.0.0.1:9765/test/test/showcase/example_html_grid/select?page=1

Looks like need to consider url_prefix here?

py4web/py4web/utils/grid.py

Line 502 in 1f460a6

self.endpoint = request.fullpath[: -len(self.path)].rstrip("/")

I've added after that line 502 in grid.py

url_prefix = os.environ.get("PY4WEB_URL_PREFIX", "") if url_prefix: self.endpoint = self.endpoint[len(url_prefix):]

plus import os

... which then breaks the 'new' button url by removing url_prefix from it

Quick fix for grid pagination link & 'new' button when using url_prefix.
