Question

在我的Ruby on Rails应用程序中，我有以下部分patients/_patient_link.html.erb

<a class="patient" href="<%= patient_path(patient_link.id) %>">
  <span class="name"><%= patient_link.name %></span>
</a>

我正在尝试使用以下代码从控制台渲染此部分：

include Rails.application.routes.url_helpers
view = ActionView::Base.new('app/views/patients', {},  ActionController::Base.new)
output = view.render(file: '_patient_link.html', locals: {patient_link: User.last, current_user: User.last})

它返回以下错误：

partial内部的href属性导致此错误：href="<%= patient_path(patient_link.id) %>"。我该如何解决这个问题？

Answer 1

我能够使用以下代码：

ApplicationController.new.render_to_string(
  :partial => 'patients/patient_link',
  :locals => { :patient_link => User.last , current_user: User.first}
)

从控制台渲染简单部分时出错
