如果符合条件,我如何在视图中写入内容?例如,如果用户plan_id为1,则显示升级订阅的链接,如果用户plan_id为12,则显示降级订阅链接。
其中一个链接是<%= link_to "Upgrade to 12 months", subscriptions_updatesubscription_path, :data => { :confirm => "Are you sure?" } %>
答案 0 :(得分:2)
这样的事情应该有效:
<% if user.plan_id == 1 %>
<%= link_to "Upgrade to 12 months", subscriptions_updatesubscription_path, :data => { :confirm => "Are you sure?" } %>
<% elsif user.plan_id == 12 %>
<%= link_to "Downgrade link", subscriptions_updatesubscription_path, :data => { :confirm => "Are you sure?" } %>
<% end %>
如果经常使用此方法,您可以将其移至辅助方法并让其返回适当的link_to
(作为下面SubscriptionHelper
中的示例):
# app/helpers/subscription_helper.rb
module SubscriptionHelper
def update_susbscription_link(plan_id)
case plan_id
when 1
link_label = 'Upgrade to 12 months'
when 12
link_label = 'Downgrade link'
end
link_to link_label, subscriptions_updatesubscription_path, :data => { :confirm => "Are you sure?" }
end
end
然后在你看来:
<%= update_subscription_link(user.plan_id) %>
