Custom maintenance
martin
Is there a way to provide custom maintenance files with webistrano? I created a task to disanle the app. The task reads am erb-file, parses the file and puts the file to the system directory. Everything else is handled by the apache configuration.
But there are several problems: the task cannot read the file, which is located in apps/views/layouts. If i call File.read("#{current_path}/app/views/layouts/maintenance.html.erb") I get an "no such file" error. That is because File.read() searches the file on my local file system and not remotely.
So how can I tell webistrano to read the file from the server? The next problem is, the maintenance file expects 2 parameters, which normally came fron the command like: REASON="database updates" cap deploy:web:disable.
Can I prompt for an value only on a specific task?
The task runs perfectly under capistrano, but I want to use this task in webistrano, too.
Thanks,
Martin

Yes, this is how random Ruby code is evaluated in
Capistrano/Webistrano - always on the system where
Capistrano/Webistrano is running on. Only `run` and `sudo` commands
are run through SSH on the remote system.
It works for you in Capistrano because there you have a local checkout
of the source, so it still executes it locally but the file is there.

Or create a Ruby script with your functionality, upload & execute it.

No, the prompt will appear on all tasks.
