ruby on rails - Couldn't find User with 'id'=1003 -

i have 1000 tips , 95 users in postgresql database , want user able create new tip , taken show page can see tip name , description along author information.

however, getting error "couldn't find user 'id'=1003" raised on line @author_firstname = user.find(params[:id]).first_name. i'm not sure why it's assigning user id new tip id, want user's id tied tip instead of tip id.

here tips controller:

class tipscontroller < applicationcontroller   def index     @tips = tip.all   end    def new     @tip = tip.new   end    def create     @tip = tip.create(tip_params)     redirect_to "/tips/#{@tip.id}"   end    def show     @tip = tip.find(params[:id])     @author_firstname = user.find(params[:id]).first_name     @author_lastname = user.find(params[:id]).last_name   end    private   def tip_params     params.require(:tip).permit(:name, :description)   end end 

and of routes:

get '/users/new', to: 'users#new'  post '/users', to: 'users#create' 'users/:id', to: 'users#show', as: 'user' 'users/:id/edit', to: 'users#edit' patch 'users/:id', to: 'users#update'  '/places/:id', to: 'places#show'  '/tips/new', to: 'tips#new' post '/tips', to: 'tips#create' '/tips/:id', to: 'tips#show', as: 'tip' 

inside tipscontroller, params[:id] give id of tip not id of user.

as, tip belongs_to user, should able user using this: @tip.user

so, show method can be:

def show     @tip = tip.find(params[:id])     @author_firstname = @tip.user.first_name     @author_lastname = @tip.user.last_name end
