Discussion:
fails when installing using a custom option; this is the service status: The issue is caused by the hardcoded database name in : the database name should be . I have not tested it directly but looking at the module source code I'm almost sure this also applies to and options. Use this service declaration:
thanks for reporting this. I've never used this service, but I would be willing to take a look and fix this if you were willing to test it for me. Sound good?
Hello Aaron, Aaron Andersen <: yes! thank you for your offer In the next couple of weeks I'll be pretty busy, but I should be able to test later on I'd also like to learn how to test local defined (i.e. in a git branch) changes to the packages/services: do you have a pointer to the relevant documentation please, just a pointer: I'll do my homework :-) Thanks!

I've found a few issues. The package in nixpkgs hasn't been updated in over 2 years. It also looks like the module author has likely moved on, so the module hasn't seen any support or maintenance in the last 2 years either. Generally at this point if no one is willing to take over maintenance of at least the package we would want to remove this from nixpkgs because this is a web application and we shouldn't have users thinking they are using something up to date and secure when it is actually lagging 7 releases (2 years) behind upstream. That being said I really don't enjoy removing software from nixpkgs that people are using, or want to use... If you're really keen on using this software on NixOS I suggest we look for a new package/module maintainer. Please let me know if you want to pursue this.
Thank you for your contributions. This has been automatically marked as stale because it has had no activity for 180 days. If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity. Here are suggestions that might help resolve this more quickly: for maintainers and people that previously touched the related code and @ mention them in a comment. on the . 3. Ask on the on .
