The problem is that I don't think I can pass the javascript array with
just link_to, I think it needs to be a javascript request. This is
the call I am using to save to the database:
@appointment = logged_in_user.appointments.build(params[:appointment])
if @appointment.save
flash[:notice] = "Availability saved"
else
flash[:error] = "There was a problem creating the
appointment."
end
where params[:appointment] is the appropriate hash. I know it is not
saving b/c it displays the error and nothing is changed in the actual
database.
This is the excerpt from the development.log:

Asked for a remote server ? true, ENV["FERRET_USE_LOCAL_INDEX"] is
nil, looks like we are not the server
Will use local index.
