Question

users_controller.rb

class UsersController < ApplicationController
    def index
        render_404
    end

    def show
        @user = User.where(:username => params[:username])

        render_404 if !@user
    end
end

basically i want to get each user data based on their username because later i want to include one more table which has meta-data for each user but i keep getting the following error

undefined method `username' for #<ActiveRecord::Relation:0x007fb5dbc52ea0>

Extracted source (around line #1):

1: <%= @user.username %> profile page

Answer 1

@user = User.where(:username => params[:username]).first try this or @user = User.find_by_username(params[:username]). Where returns AR::Relation, not an ActiveRecord object.
