Try running rake routes for more information on available routes.

As routing error suggest you should "try running rake routes for more information on available routes." The point is you obviously have not specify route rule for add_einheit method

resources :sportlers

This code will only creates routes about CRUD actions(create,new,edit,update vss...) To use "add_einheit" actions edit routes.rb ;

resources :sportlers do
    member do
        get "add_einheit"
    end
end

If you send a parameter like "id" use "member do" else use "collection do" in your routes.rb file.

That's because your template isn't in the right place for this action. Either move your template to 'sportlers/add_einheit' or force it to render your template using render :action => :edit, :controller => :einheits

Are you sure you have a html file under sportlers view folder, like view/sportlers/add_einheit.html.erb ?

no, but _form.html.erb, edit.html.erb, new.html.erb, show.html.erb

add_einheit is a method in my controller

kader Over a year ago

your html file has to have the same name with your method, if you do not point a spesific html file in your method block. so if you have a add_einheit method in sportlers controller and you want to render a html file from this method, you set /sportlers/add_einheit.html.erb file.

I took Kaders solution. It functions but now i geht the next Routing Error. action => sportlers/update_einheit doesnt function. I dont understand the princip.

FITAPP2::Application.routes.draw do resources :sportlers do member do get "add_einheit" get "update_einheit" end end end

I try to extends the routes above with a second entry get update_einheit - it doenst function Routing Error

No route matches {:action=>"update_einheit", :id=>#, :controller=>"sportlers"} Try running rake routes for more information on available routes.

rake routes:

add_einheit_sportler GET /sportlers/:id/add_einheit(.:format) sportlers

add_einheit

update_einheit_sportler GET /sportlers/:id/update_einheit(.:format) sportlers

update_einheit

          sportlers GET    /sportlers(.:format)                    sportlers

index

                    POST   /sportlers(.:format)                    sportlers

create

       new_sportler GET    /sportlers/new(.:format)                sportlers

new

      edit_sportler GET    /sportlers/:id/edit(.:format)           sportlers

edit

           sportler GET    /sportlers/:id(.:format)                sportlers

show

                    PUT    /sportlers/:id(.:format)                sportlers

update

                    DELETE /sportlers/:id(.:format)                sportlers

destroy
