Question

Currently getting an undefined method and I am unsure how to fix this issue, been stuck on this for a while now. All help is much appreciated!

NoMethodError in Users#show

undefined method `comments' for nil:NilClass

Extracted source (around line #2):

1: <div class="CommentField">
2: <%= form_for ([@micropost, @micopost.comments.new]) do |f| %>
3: <%= f.text_area :content, :class => "CommentText", :placeholder => "Write a Comment..." %>
4: <div class="CommentButtonContainer">
5: <%= f.submit "Comment",

User Controller

class UsersController < ApplicationController
  def show
    @user = User.find(params[:id])
    @school = School.find(params[:id])
    @micropost = Micropost.new
    @comment = Comment.new
    @comment = @micropost.comments.build(params[:comment])
    @microposts = @user.microposts.paginate(:per_page => 10, :page => params[:page])
  end
end

Comment Controller

class CommentsController < ApplicationController 
  def create
    @micropost = Micropost.find(params[:micropost_id])
    @comment = @micropost.comments.build(params[:comment])
    @comment.user_id = current_user.id
    @comment.save 
      respond_to do |format|
      format.html 
      format.js
    end
  end
end

I hate to tell you this but you have a typo. You typed @micopost.comments.new instead of @micropost.comments.new. Correct that and it’ll fix this problem.
