9.MemCacheStore 缓存
@_cache = ActiveSupport::Cache::MemCacheStore.new(
CONFIG['host'], { :namespace => "#{CONFIG['namespace']}::#{@name}" }
)
localhost::callback_lock
@_cache.write(pay_channel.channel_id,'true')
v = @_cache.read(pay_channel.channel_id)
if v.nil? || v != 'true'
return false
else
return true

13. Time
start_time = start_time.to_s.to_datetime.at_beginning_of_day
end_time = end_time.to_s.to_datetime.end_of_day
14.merchant.instance_of? MplusMerchant
m_order[:merchant_id] = (merchant.instance_of? MplusMerchant) ? merchant.id : merchant
15.will_paginate rails
安装之后需要修改config/environment.rb文件
在文件的最后添加:
require 'will_paginate'
修改controller文件中的index方法:
# @products = Product.find(:all)
@products = Product.paginate :page => params[:page],
:per_page => 2
.pagination
= will_paginate @mplus_orders, :class => 'digg_pagination'
最好有个include
