Well i just didn't think about the option. Thank you a lot , i got it now. Can i ask you another Question?
I have different Buildings and it should be possible to upgrade these buildings. So my link to count the points looks like this now: <%= link_to 'Update', village_path(@village), :method => :put %> It uses the conventional update action now, but writing the code for an Building_upgrade action in this update action doesn't sound good to me. So can i write an action in the village controller and use it like this? <%= link_to 'Update', village_path(@village), :method => :put , :action => building_upgrade %> or how can i handle this?
