如何在 new.js.erb 中使用局部变量 f 渲染 RAILS 部分? [英] How to render a RAILS partial with local variable f in new.js.erb?

问题描述

有一种方法可以像这样在 js.erb 中渲染 erb 页面，在 rails 中使用 :remote => true :

There is a way to render a erb page in js.erb like this with :remote => true in rails:

$('#invoice_against_lease').html('$("<%= j render(:file => 'invoice/new.html.erb') %>")');

我们有一个像这样的部分_customer_quote_record:

We have a partial _customer_quote_record like this:

   <%= f.input :quote_id, :label => 'Quote#：', :collection => quotes_for_invoice(@customer), :include_blank => true %>
   <%= f.hidden_field :_destroy %>  

部分在 html.erb 中呈现为这样，并传递局部变量构建器:

The partial is rendered in html.erb as this, with passing local variable builder:

<%= f.simple_fields_for :invoice_items do |builder| %>
  <%= render 'customer_quote_record', :f => builder %>
<% end %>

尝试了以下代码:

$('#invoice_against_lease').html('$("<%= j render(:file => 'customer_lease_record', :f => f) %>")');

错误是"ActionView::Template::Error (undefined local variable or methodf'..."`

有没有办法在js.erb中渲染上面的部分?

Is there a way to render the partial above in js.erb?

推荐答案

尝试以下操作:

$('#invoice_against_lease').html('$("<%= j render(:partial => 'customer_lease_record', :locals => {:f => f}) %>")');

这当然假设 f 在您进行此调用的任何地方都已定义.如果不同，只需更改 :locals =>{:f =>f} 到 :locals =>{:f =>"YOUR_VARIALBE"}

This of course assumes that f is defined wherever you make this call. If it's different, just change :locals => {:f => f} to :locals => {:f => "YOUR_VARIALBE"}
