Rails:无法将变量传递给部分，我做错了什么? [英] Rails: can't pass variable to partial, what am I doing wrong?

问题描述

我正在尝试几种不同的方法来定义局部变量并将其传递给局部变量，但它一直说它未定义:

I'm trying a few different ways to define and pass the local variable to the partial, but it keeps saying it's undefined:

在显示文件中:

<% @startups.each do |startup| %>
  <%= render :partial => "profile/startup" %>
<% end %>

部分:

<%= simple_form_for [@commentable, @comment], :remote => true do |form| %>
  <%= form.input :content, label: false, :input_html => { :id => "#{startup.user_id}" } %>
  <%= form.submit "Submit" %>
<% end %>

这些是我尝试传递变量的其他方式，但仍然未定义:

These are the other ways I'm trying to pass the variable, but still getting undefined:

<%= render :partial => "user_comments/uac",  object: startup, as: startup %>
<%= render :partial => "user_comments/uac",  collection: startup, as: startup %>
<%= render :partial => "user_comments/uac", :locals => {:startup => startup} %>

推荐答案

去掉 :partial.您在多个版本的 Rails 中都不需要它.

Get rid of :partial. You haven't needed that in Rails for several versions.

将名为 startup 的局部变量传递给局部变量的正确方法是:

The correct way of passing a local called startup to a partial is this:

render "profile/startup", startup: startup
