### Infos: - Used Zammad version: 3.7.0 - Used Zammad installation source: source - Operating system: NixOS ### Problem: I’m trying to package Zammad for NixOS. This is a stateless distribution, and it uses a sandbox for building. I have only weak Ruby skills. I’ll need to package it in such a way that the app is in a certain folder with the compiled assets and all application state is in e.g. `/var/lib/zammad`. I got as far building the gemset, and I’m now trying to precompile the assets. The problem is that packages are built in a network-less sandbox. when I run ``` cp config/database/database.yml config/database.yml bundle exec rake rake:assets:precompile RAILS_ENV=production NODE_ENV=production ``` it errors out, wanting to connect to PostgreSQL. How can I make it skip the DB connection? ---

I found support for NullDB, but when I set the database adapter to `nulldb`, I get this error > ---

You can’t skip the database connection. It’s deeply soldered in the application to ensure everything is up and running that’s needed. ---

@MrGeneration Isn’t it a bit strange to require database connection to compile some javascript? ---

Well I get what you’re aiming at, but sorry, that’s not my cup of tea. I can’t tell if there’s a good reason for it. 🤷‍♂️ Maybe @anon29869905 can. ---

As mentioned before this is default Rails behaviour and not directly related to Zammads codebase. I googled for a minute and found [a straight forward workaround](http://www.carlos-roque.com/2020/12/09/assets-precompile-without-a-database-in-rails-4-and-5/): 1. Added this gem to the Gemfile ```auto gem "activerecord-nulldb-adapter" ``` 1. Modified the assets precompile command to look like this: ```auto bundle exec rake DATABASE_URL=nulldb://user:pass@127.0.0.1/dbname assets:precompile ``` We can take part 1 into the core to reduce the [zammad-docker](https://github.com/zammad/zammad-docker/blob/b16ae60cb9961c9576718af5fb67d7f1b64a2c47/install-zammad.sh#L76) and [zammad-docker-compose](https://github.com/zammad/zammad-docker-compose/blob/8eadbd39a1233d527dd6210667e0451e8eec221b/containers/zammad/setup.sh#L33) setup time. However, our resources are limited. Since this is a pretty low hanging fruit contributions from the community are very welcome. ---
