Dear all: I'm new to Rails and I've encountered some problems with ajax in Rails 3. My project is on a Ubuntu 10.04 LTS machine with ruby v1.8.7 and rails v3.0.0.
I've changed my rails.js file according to :
and also changed my javascript_include_tag to these three paths:
1."http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" 2."http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js" 3."rails.js"
Everything works just fine except a controller with a ssh connection behavior.
In my malfunctioned controller:
def remoteStatus @ip = params[:server][:ip] @sshid = params[:server][:sshid] @sshpass = params[:server][:sshpass] Net::SSH.start(@ip, @sshid, :password => @sshpass) do | session.exec!("free | awk 'NR==2 {print rate = $3/$2*100}'") do
channel, stream, data|
@memusage = data end end respond_to do |format| format.js end end
In the remoteStatus.js.erb I have:
$('#status_div').append("<%=@memusage%>")
I am pretty sure that I can have the ssh connection result in variable @memusage. But it seems that it never appends to the status_div block in the corresponding view. I'm wondering if I am missing something detailed. Can anyone help me here,please and thanks!
Best regards
