使用 Rails 3 根据文本字段值显示数据

Question

我有一个问题。我想根据文本字段值从数据库中获取数据。这个文本字段将采用两种类型的值。第一个是简单的数字（例如-123456789），第二个是这样的（例如-123456789/1)。DB 中存在一个表的简单数字。在“/”之后的第二个数字（即 1）是另一个表的 ID，它与第一个表相关联。那么我的目标是用户何时给出输入“123456789”数据将根据该数字通过搜索获取​​，当用户首先输入“123456789/1”时，它将拆分数字并根据数字和id（即123456789和1）获取值) 来自两个表。

我在下面解释我的一些代码。

        else
            flash[:alert]="Record could not create"
            flash[:color]="invalid"
            render 'hcsy_details_master'
        end

    end
end

这里我已经完成了简单的数字，请帮助我通过第二个输入数字（即 123456789/1）从两个表中获取数据。为此，所有操作都在“scan_hcsy”方法中执行。至少帮助我拆分number(i.e-123456789/1) 到 123456789 和 1 以便我可以根据这个数字和 id 获取数据。

你可以把字符串拆分成一个数组：

"12345678/1".split('/')
=> ["12345678", "1"]

在你的情况下：

splitted = params[:hcsy][:reciept].split('/')
hcys = splitted[0]
table_id = splitted[1]
