undefined local variable or method `stop' for #<#<Class:0xb085c0a4>:0xb16e8c6c> - ruby-on-rails

Question

I know this is a very common issue, but I can't resolve this with any of the other topics.
this is the issue:
undefined local variable or method `stop' for #<#:0xb16e8c6c>
app/views/stops/show.html.erb
<p id="notice"><%= notice %></p>
<p>
<strong>City name:</strong>
<%= #stop.city %>
</p>
<p>
<strong>Arrival time:</strong>
<%= #stop.Arrival_time %>
</p>
<p>
<strong>Route:</strong>
<%= #stop.Route_id %>
</p>
<%= link_to 'Edit', edit_stop_path(#stop) %> |
<%= link_to 'Back', stops_path %>
db/schema.rb
create_table "stops", force: :cascade do |t|
t.time "Arrival_time"
t.integer "Route_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "city"
end

# Use callbacks to share common setup or constraints between actions.
def set_stop
#stop = Stop.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def stop_params
params.require(:stop).permit(:city, :Arrival_time, :Route_id)
end
end
I don't see where the problem is.. can you help me? thank you

You're getting this error because #stop isn't defined on the show page. You fix this by defining it in the show method in your Stop Controller.
I'm assuming the show page will pass a parameter for the shop id. If so you can define it like this:
def show
#stop = Stop.find(params[:id])
end
