used_cars = UsedCar.paginate(:page => params[:page], :per_page => 5)
used_cars_hash = used_cars.as_json
我在视图中显示所有used_cars_hash。但是当我添加<% will_paginate @user_cars_hash %>
时
它给出了一个错误
如何在阵列上显示分页计数器?
因为我们添加<% will_paginate @user_cars_hash %>
它出错了
未定义的方法total_pages' for #<Array:0x007f1edef43c48>

will_paginate
不适用于通过调用used_cars.as_json
得到的普通Ruby数组。尝试将used_cars
传递给它:
# no need to turn it into a plain array
@used_cars = UsedCar.paginate(:page => params[:page], :per_page => 5)
# in the view:
<%= will_paginate @used_cars %>
如果你绝对必须使用数组进行分页,你可以这样做:
require 'will_paginate/array'
# you can call `paginate` on plain arrays
used_cars = UsedCar.all
@used_cars_array = used_cars.as_json.paginate(:page => params[:page], :per_page => 5)
# in the view:
<%= will_paginate @used_cars_array %>
