Trying to learn ruby on rails by creating a reddit clone.
So now I'm trying display the username of the user who created the post, but I'm only getting it displayed as u/username everywhere.
Also when I try to click on u/username to see if I can get data about user by going to his page, all I'm getting is an error saying:
undefined method `username' for nil:NilClass
This is my partial _list class that displays data about post:
<% posts.each do |post| %>
<%= link_to post.community.name %> | Posted by <%= link_to post.account.username, profile_path(:username) %> <%= time_ago_in_words post.created_at%> ago. </p> </small>
<%= link_to post.title, community_post_path(post.community_id, post) %>
<%= truncate post.body, length: 200 %>
<% end %>
profile.html.erb just to display username for now:
<%= @profile.username %>
account.rb:
class Account < ApplicationRecord
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :validatable
has_many :posts
has_many :communities
validates_presence_of :username
end
public_controller:
class PublicController < ApplicationController
def index
@communities = Community.all.limit(5)
@posts = Post.order(id: :desc).limit(20)
end
def profile
@profile = Account.find_by_username params[:username]
end
end
post.rb:
class Post < ApplicationRecord
belongs_to :account
belongs_to :community
validates_presence_of :title, :body, :account_id, :community_id
end
and routes.rb:
Rails.application.routes.draw do
devise_for :accounts
get "u/:username" => "public#profile", as: :profile
resources :communities do
resources :posts
end
root to: "public#index"
end
