首先,我是红宝石的新手。我正在从头开始建立一个论坛以获取乐趣。
完成授权工作,并且可以发布带有原始内容的新主题,但我对帖子(回复)控制器有问题。
这是我得到的错误:
SyntaxError in PostsController#new
/Users/mlegacy/Documents/RubyProjects/forum/app/controllers/posts_controller.rb:48: syntax
error, unexpected keyword_end, expecting $end
这是我的控制器代码:
class PostsController < ApplicationController
def index
@posts = Post.order("sticky desc")
end
def show
@post = Post.find(params[:id])
end
def new
@post = Post.new
end
def create
@post = Post.new(post_params)
@post.user = current_user
if @post.save
redirect_to topics_url, notice: "Post created."
else
render :new
end
end
def edit
@post = Post.find(params[:id])
end
def update
@post = Post.find(params[:id])
redirect_to topics_url, notice: "Updated post."
else
render :edit
end
end
def destroy
@post = Post.find(params[:id])
@post.destroy
redirect_to topics_url, notics: "Post removed."
end
private
def post_params
params.require(:posts).permit(:content, :created_at, :updated_at)
end
end
我的模型:
class Post < ActiveRecord::Base
belongs_to :topic
end
然后是 topic#show 视图和 posts#new 视图:
主题#显示:
<h1><%= @topic.name %></h1>
<p><%= @topic.post_content %></p>
<% @topic.posts.each do |post| %>
<div class="post">
<%= post.content %>
</div>
<% end %>
<p><%= link_to "Post new reply", posts_new_path %></p>
<p><%= link_to "Back to topics", topics_path %></p>
帖子#new
<h1>New Post</h1>
<%= render 'form' %>
