Unable to load graphs and images in wiki

[nitishhombal]

Hi,
Greetings. I am upgrading our redmine from 2.5.2 to 3.4.5 on a different VM (RHEL 7). While I have configured most of the plugins, I am stuck with wiki page that loads a graph and image. For some reason I am not able to efficiently use or configure wiki_graphviz_plugin. Could someone please help, I guess I am missing some configurations here.

I had asked the IT team to install graphviz software as I did not have root access and I could not install the software because of permission issues.

Attahced are the screenshots of wiki page in old redmine (where it works fine) and new server where it is not.

1. It seems that there is no screenshots are attached to this issue.
2. Following is my environment. It rendered graph images correctly.
   I recommend you try it with minimum configuration to clarify the issue.

Hi,
Thank you very much for quick response.
I am unable to attach the screeshots here and I am sending them to your email ID [email protected] now.
Would you please check the screenshots once and advise, in the meanwhile I check removing all configuration and retain only graphviz.

Also, based on my environment, would you be able to advise if there are any incompatibilities between the versions used? Ruby or Graphviz?

Are there any specific settings post graphviz installation? I don't have rights to install grapghviz adn I had to depend on our IT team, would you mind sharing the steps you followed for grapghviz installation?

Thanks,
Nitish

I think the possibility is low, because both ruby and graphviz version difference between our environments are little.

Are there any specific settings post graphviz installation? I don't have rights to install grapghviz adn I had to depend on our IT team, would you mind sharing the steps you followed for grapghviz installation?

In my environment (CentOS 7), I just executed yum install -y graphviz .

Hi,
Thank you very much. I have requested the IT dept to try the same commands.
Did you get the screenshots that I had sent on your email, would you please check and suggest what I could be missing with on my environment.
We actually have an old redmine server (2.5.2) and the same plugin works well there.

Thanks.,
Nitish

I am just trying this plugin out. on Redmine 4.0.4. No graph is displayed. Is this plugin compatible with Redmine4?

[goutnet]

for the record, I tested this plugin, and works on 4.2.0 stable

Hi,

Doesn't work for me on Redmine 4.2.2.

No graph is displayed, but I see the {{graphviz_link() … }} source rendered in the wiki page.
It seems like the plugin doesn't pick up the macro to replace it with the rendered image.

The Redmine log file shows that the plugin is actually called during the rendering process (two last lines):

Started GET "/projects/infrastructure/wiki/Foo" for 212.123.14.2 at 2021-10-12 09:53:19 +0000

I have a fresh Redmine 4.2.2 install with only the wiki_graphviz plugin installed.

Kind regards,
