ruby on rails - No route matches [GET] -


i'm trying add 'add cart' method items.

items_controller:

def to_cart   @item = item.friendly.find(params[:id])    @item.add_to_cart   redirect_to root_path end

routes:

resources :items   put :to_cart, on: :member end

model:

def add_to_cart   current_user.cart.items << self   current_user.cart.save end

show:

<%= @item.name  %> <%= link_to 'add cart', to_cart_item_path(@item) %>

i got routingerror: no route matches [get] "/items/first/to_cart" 'first' because of friendly id. did wrong?

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
