Question

我有Sinatra个应用，正在使用Padrino。当我使用content_for帮助器在布局中呈现内容时，它将其作为字符串而不是html返回。

app.rb

class CateringApp < Sinatra::Application
  register Padrino::Helpers
end

layout.erb

<div id="page-wrapper">
  <%= flash[:notice] %>
  <%= content_for?(:main_table) ? yield_content(:main_table) : yield %>
</div>

category.erb

<% content_for :main_table do %>
  <div id="name" class="row">
    "IM ALIVE"
  </div>
<% end %>

我在浏览器上获得的结果是文字字符串

<div id="name" class="row">
   "IM ALIVE"
</div>

app.rb

require 'dotenv'
Dotenv.load

require 'sinatra'
require 'sinatra/activerecord'
require 'sinatra/reloader'
require 'sinatra/flash'
require 'sinatra/assetpack'
require 'padrino-helpers'

class CateringApp < Sinatra::Application
  enable :protect_from_csrf
  use Rack::Session::Cookie, :secret => ENV['SESSION_SECRET']
  register Padrino::Helpers
  register Sinatra::AssetPack
end

# require all config files
Dir["./config/*.rb"].each {|file| require file }
require './auth'

Gemfile.lock

Answer 1

在您的Gemfile中加入gem 'erubis'。

Padrino ::渲染只有在相应的宝石（erubis，haml或slim）被包含在捆绑中并且在需要'padrino-helpers'时可见时才能被激活。

Padrino content_for渲染字符串而不是HTML
