[英]Rails and Searchlogic: finding products that matching all given product categories by using searchlogic condition
I have a model Publication and a model Category in my Rails app. 我的Rails应用程序中有一个模型出版物和一个模型类别。 Both are connected with a has_and_belongs_to_many association.
两者都通过has_and_belongs_to_many关联进行连接。
Now I would like to search publications that match one or more categories. 现在,我想搜索与一个或多个类别匹配的出版物。 If more than one category is given they have all assigned to the publication.
如果给出多个类别,则将它们全部分配给发布。 I want to specify the categories in a multiple select_box.
我想在多个select_box中指定类别。
Publication.released.categories_id_is([1,2])
is not working because the categories are connected with OR. Publication.released.categories_id_is([1,2])
不起作用,因为类别与OR关联。
With Publication.categories_id_is_all([1,2])
the categories are connected with AND, but no result is given back. 使用
Publication.categories_id_is_all([1,2])
,类别通过AND连接,但未返回结果。
Any idea's on that? 有什么想法吗? Am I mising the right point in the docs.
我是否在误导文档中的正确点? Thanks for your very welcome help!
非常感谢您的帮助!
Take a look at the logs to see what SQL query is actually being run for those commands. 查看日志以查看那些命令实际上正在运行什么SQL查询。
