如何在 Rails 中渲染视图 [英] How to render view in rails

问题描述

我正在为我的应用程序使用 rails.我已经为 crud 操作生成了脚手架.我有 product_lists 的脚手架.我有一个名为 user_dashboard.html.erb 的页面，我想从 product_lists 呈现页面.

我在 pages/ 目录中有 user_dashboard.html.erb 页面..我想从 user_dashboard.html 内的 product_lists 目录呈现 index.html 页面.erb.我试过使用渲染..但它的显示错误这是我尝试过的

<%= 渲染 'product_lists' %>

错误:

ActionView::MissingTemplate in Pages#user_dashboard

我该如何解决这个错误，为什么会出现这个错误?

解决方案

它不是部分(以下划线开头)，所以你需要渲染模板.您还需要模板的完整路径，来自视图目录:

<%= 渲染模板:'product_lists/index' %>

i am using rails for my application.i have generated scaffold for crud operation. i have scaffold for product_lists. i have page called user_dashboard.html.erb here i want to render pages from product_lists.

i have user_dashboard.html.erb page in pages/ directory..i want to render index.html page from product_lists directory inside user_dashboard.html.erb. i have tried using render.. but its showing error here is what i have tried

<div class="panel-body">      
        <%= render 'product_lists' %>
</div>

error:

ActionView::MissingTemplate in Pages#user_dashboard

How can i solve this error and why is this raised?

解决方案

It is not a partial (starts with underscore), so you need render template. You also need the full path of the template, from the view directory:

<%= render template: 'product_lists/index' %>
