Hi all,
I keep getting this error message when I try to go to a users page.
NoMethodError in ProfilesController#show undefined method `find_by_profile_name'
class ProfilesController < ApplicationController def show @user = User.find_by_profile_name(params[:id]) if @user @posts = Post.all render actions: :show
Any help would be greatly appreciated! Thanks

To find this user, we need profile_name column in users table. See if in schema.rb like this..
create_table "users", force: true do |t|
t.string "profile_name"

Also, check out the markdown cheatsheet linked below the reply box for info on how to format code. It makes things much easier to read.
