问题描述
表单:
<%= form_for Like.find(post.user.likes), :html => { :method => :delete , :class => "unlike_post_like_form" } do |f| %>
发布模型
belongs_to :user
has_many :likes
用户模型
has_many :posts
has_many :likes
类似模型
belongs_to :post
belongs_to :user
我不断收到以下错误:
TypeError in Users#show
Cannot visit Like
在
Like.find(post.user.likes),
第一个解决方案:
改变
Like.find(post.user.likes),
到
Like.find(post.user.likes).limit(1),
第二个解决方案:
改变
Like.find(post.user.likes),
到
current_user.likes.where(:post_id => post.post_id)
推荐答案
Like.find(post.user.likes)试图查找给定likes数组的Like.那真的没有多大意义.
Like.find(post.user.likes) is attempting to find a Like given an array of likes. That doesn't really make much sense.
您很有可能想搜索post.user.likes，但是即使那样，我还是有些困惑-您需要发布更多代码.
Most likely, you'll want to search post.user.likes, but even then, I'm a bit confused - you'll need to post more code.
Like.find正在寻找id(整数)或包含键和值的哈希.数组不提供任何搜索信息.
Like.find is looking for either an id (integer), or a hash containing keys and values. An array doesn't give it any information to search.
编辑:如果您正在寻找当前用户的喜欢.您需要执行以下操作...
If you're looking for the likes of current user. You'll need to do the following...
current_user.likes.where(:post => @post)
