[英]Render from Helper yields “Missing Template” error
在我的優惠券視圖中,我在helpers / coupons_helper.rb中調用一個方法,該方法進而調用部分函數以返回其輸出。 但是我收到“缺少模板”錯誤。 以下是相關代碼:
views/coupons/show.html.erb:
...
<%= form_for(@coupon) do |f| %>
<% new_include(f) %>
<% end %>
helpers/coupons_helper.rb:
def new_include(f)
new_object = Participation.new
fields = f.fields_for(:participation, new_object, :child_index => :new_include) do |builder|
render "_locations_include", :f => builder
end
end
views/coupons/_locations_include.html.erb:
Include: <%= f.select :participant_id, @groups %><br>
錯誤消息是:
Missing partial coupons/_locations_include with {:handlers=>[:erb, :builder, :rjs, :rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} in view paths "/Users/jackrg/Documents/YummiApps/yummi1/app/views"
問題原來是“ new_include”中“ render”中的前導“ _”。 問題解決了。
您不能在render
調用中為下划線添加前綴:
render "locations_include", :f => builder
附帶說明一下,在文件名中添加_include
后綴可能有點多余,因為.erb文件以下划線開頭表示該文件是部分文件。
