You have a typo:
before_filter :correct_user, only: :destory
:destory
should be :destroy
, this is causing @micropost
to be nil. You make the same spelling error in the other before_filter btw.
سؤال
I'm working through the rails tutorial and have run into an error.
$ bundle exec rspec spec
Failure/Error: expect { click_link "delete" }.should change(Micropost, :count).by(-1)
NoMethodError:
undefined method `destroy' for nil:NilClass
There are two errors, caused by this same issue of an undefined method 'destory' for nil:NilClass
Micropost controller
class MicropostsController < ApplicationController
before_filter :signed_in_user, only: [:create, :destory]
before_filter :correct_user, only: :destory
def create
@micropost = current_user.microposts.build(params[:micropost])
if @micropost.save
flash[:success] = "Micropost created!"
redirect_to root_path
else
@feed_items = []
render 'static_pages/home'
end
end
def destroy
@micropost.destroy
redirect_to root_path
end
private
def correct_user
@micropost = current_user.microposts.find_by_id(params[:id])
redirect_to root_path if @micropost.nil?
end
end
I think that is all the information that is needed to help me figure out this issue. Here is some more anyways.

I tried their solution, but it made no difference.
_feed_item.html.erb
<li id="<%= feed_item.id %>">
<%= link_to gravatar_for(feed_item.user), feed_item.user %>
<span class="user">
<%= link_to feed_item.user.name, feed_item.user %>
</span>
<span class="content"><%= feed_item.content %></span>
<span class="timestamp">
Posted <%= time_ago_in_words(feed_item.created_at) %> ago.
</span>
<% if current_user?(feed_item.user) %>
<%= link_to "delete", feed_item, method: :delete,
confirm: "You sure?",
title: feed_item.content %>
<% end %>
</li>
Thanks
