Hi everyone, I''m at the end of my rope on this. I can''t get pagination to work with anything but a standard find on a model. If I try to do a search and customize the pagination, I get lots of different variations.

Struggling a bit with rendering a partial in an RJS template. I''m having to feed the javascript directly to the page object as couldn''t find a way to have insert_html work directly on the proxy object returned by select. However, that''s not the problem.

Is there a count_by_content alternative to the find_by_content action?

There must be a better way to write this code: @project_pages, @projects= paginate :project, :per_page => 10, :conditions => ["account_id = ?", account] ?!

Hello, maybe that I''m a stupid, but I don''t know how I can working with pagination. In all examples is written (for example) next: def user_list @user_pages, @users = paginate(:users, :order_by => ''name'') end So, it''s OK (as a scaffold) for all set of users.

Hi, after trying sshfs to mount a remote file system on a server with the result that sshfs will sooner or later get stuck and require a reboot of the client, I'm fed up with it and am looking for alternatives. So next I would like to use NFS over a VPN connection instead. To minimize the instances of the NFS mount getting stuck, it might be helpful to use autofs. What happens when the
