Clarification on Editing Settings for CADViewer Integration in NextCloud AIO Docker Setup

[SinghNanak]

I am currently using Ubuntu 22.04 and have NextCloud AIO set up using Docker. I have a question regarding the process of editing the settings for CADViewer integration. Specifically, I would like to know whether I should make these edits inside the Docker container or on the Ubuntu host system. Could you please provide me with a step-by-step guide to clarify this?

Hello @nanaksingh13 , there are two things that needs to be done, possibly you have to change the permissions of the back-end CAD converter and folders where the conversion takes place, you can see that in: https://github.com/CADViewer/NextCloud/blob/main/README.md , all is happening in the /apps/ folder from NextCloud, so /apps/cadviewer. This will likely be inside your docker container. Secondly, the php scripts that CADViewer uses to communicate with the back-end needs to be properly redirected, therefore you may need to update the rewrite rules in the .htaccess file. (yes, we are due to make an updated user guide available on our site). Hope this helps, please get in touch as you move forward.

I am getting confused. I download cad viewer from Appstore inside nextcloud and there is no cadviewer

[CADViewer]

Hello @nanaksingh13 , so NextCloud will have a folder called /apps/ which contains all the apps that are installed into NextCloud, so you need to locate that folder. FYI: I am running NextCloud on Ubuntu 20.04 WSL, and there the path structure is /var/www/html/(nextcloud)/apps/cadviewer. I can check with a developer who is running docker, but I think you will have to step inside the container image nextcloud/aio-nextcloud.

[SinghNanak]

will try, better if i know about AIO docker. I couldn't find it last time.

[SinghNanak]

@CADViewer waiting for your clarification

[SinghNanak]

any updates? how to configure in nextcloud AIO

[kevmax1]

Hi @nanaksingh13, can you tell me exactly where you're having trouble getting Cadviewer to work on a docker AIO install?

[SinghNanak]

can you provide details for CADViewer installation on Docker AIO. I am using app store to install CADViewer. In which container, Excecute permission script is available?

[kevmax1]

You need to connect interactively to the nextcloud docker container with the command docker exec -it id_of_container (you get the id with docker ps) and once inside you need to modify the .htaccess file with vim (you install it with these 2 commands: apt-get update, apt-get install vim) and the content to put in your .htaccess is as follows:

<IfModule mod_headers.c>

thx will try it
