Ruby on Rails - 如何将哈希参数传递给局部视图？

Question

'shared / subscription'％＆gt;

要调用此部分视图：

<% form_for(:subscription, :url => city_subscriptions_path(@city)) do |form| %>
  <%= form.hidden_field :city_id, :value => @city.id %>
  <%= form.text_field :email, :size => 30 %>
  <%= form.submit "Email Me" %>
<% end %>

由于我在不同的地方使用这个局部视图，我如何更改调用者以便它将传递form_for助手的哈希值？所以当调用帮助程序时会是这样的：

<% form_for(:subscription, :url => city_subscriptions_path(@city), :html => {:id => 'main_input' }) do |form| %>
  <%= form.hidden_field :city_id, :value => @city.id %>
  <%= form.text_field :email, :size => 30 %>
  <%= form.submit "Email Me" %>
<% end %>

Answer 1

<%= render :partial => "shared/subscription", :locals => {:foo => "bar", :foofoo => ["bar", "bar"]}

在局部视图中，使用它们：

<%= foo #this outputs "bar" %>
<%= foofoo.to_s %>
