I am having the same issue as the person above did. Moderator zystvan, in your reply you say, "I think that the code you posted belongs in app/views/tags/index.html.erb, not show.html.erb, but I'd like to check the exercise :slightly_smiling." That is good information to have because the instructions to the exercise tell the programmer to insert the code into "app/views/tags/show.html.erb." See below:
Finally in app/views/tags/show.html.erb below a destination's description, use link_to to add a link to that destination:
◼Use "See more" for the link text
◼By giving the show route a name of "destination", Rails automatically creates a helper method named destination_path. Use destination_path to generate a URL to a specific destination's path.
So is there an error in the instructions? That's probably why everyone is having the same problem.
