印象派 gem - 按浏览量对帖子排序
Impressionist gem - sort posts by views
我正在使用以下 gem，现在我正在尝试按观看次数对 post 进行排序。
我在我的 post 模型中遵循了说明，所以我有：
is_impressionable :counter_cache => true
在我的控制器中，我有：
@mostpopular = @posts.order('counter_cache DESC').limit(6)
但是我收到一个错误：
SQLite3::SQLException: no such column: counter_cache: SELECT "posts".* FROM "posts" ORDER BY counter_cache DESC LIMIT 6
您是否在模型中添加了字段？
is_impressionable :counter_cache => true
This will automatically increment the impressions_count column in the
included model. Note: You'll need to add that column to your model.
要添加你可以这样做：
t.integer :my_column_name, :default => 0
