haml 的问题我在 rails 上研究 Ruby 偶然发现了以下内容

problem with haml I study Ruby on rails stumbled where with the following

Posts#index 中的名称错误 显示 /home/alexandr/Huntjob/app/views/posts/index.html.haml 第 4 行出现的位置:

#<#:0x00005621a21d4538> 的未定义局部变量或方法“haml_temp” 你的意思? haml_tag enter image description here

错误代码

- @posts.each do |post|
=link_to (image_tag post.image.url(:small))
%h2= link_to post.title, post
= link_to "Add New Inspiration", new_post_path

Post控制器

class PostsController < ApplicationController
before_action :find_post, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!, except: [:index, :show]

def index
@posts = Post.all.order("created_at")

end

def show

end

def new
@post = current_user.posts.build
end

def create
@post = current_user.posts.build(post_params)

if @post.save
  redirect_to @post
else
  render 'new'
end
end

def edit
end

def update
if @post.update(post_params)
  redirect_to @post
else
  render 'edit'
end
end

def destroy
 @post.destroy
 redirect_to root_path

 end

 private

 def find_post
  @post = Post.find(params[:id])
  end

  def post_params

  params.require(:post).permit(:title, :link, :description, :image)
  end


   end

HAML 对缩进敏感。从屏幕截图中我看到问题出在缩进中。

应该可行:

- @posts.each do |post|
  = link_to(image_tag post.image.url(:small))
  %h2= link_to post.title, post
= link_to "Add New Inspiration", new_post_path

确保第 2 行和第 3 行之前有两个空格。
