net/http.(*Server).Serve error

[ghost]

Hi guys,

Hope you are all well !

I try to run qor-admin from a docker container, and it is triggering a weird error from net/http package.

ref. https://github.com/x0rzkov/oniontree

docker-compose up

gives me the following error

Does anyone know what is happening ?

@x0rzkov out of box qor admin is not compatible with go modules. The error occurred because template was not found. https://github.com/qor/auth/issues/23#issuecomment-569522292

Accordingly to https://doc.getqor.com simples solution is to compile templates into binary via https://github.com/qor/bindatafs

Would be awesome to have a gist or repo with an example running bindatafs and qor admin.

@x0rzkov just follow https://doc.getqor.com/guides/bindatafs.html and dive into source code

repo: https://github.com/sergolius/qor_bindatafs_example I tried to commit step by step

awesome, thank you very much !

@sergolius , hope you are all well !

I was just wondering if you have any idea how to sort another issue I posted https://github.com/qor/auth/issues/42

I am locked and need to find at least some hints about how to do it ^^.
