Ruby on Rails - 如何将散列参数传递给部分视图？

Question

的共享/订阅“％>

要调用这个局部视图：

<% 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 %> 

由于我使用不同的地方这部分观点，我该如何改变主叫以便它能够传递一个哈希的form_for帮手？因此，这将是这样的当帮手叫：

<% 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"]} 

在您的局部视图，使用它们：

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