Question

希望根据Rails 2.0.2中的条件限制查找。

查找声明：

@employees = Employee.find_by_contents(params[:keywords].to_s, :include => [ :categories, :revisions, :approvals, :archives, :related_documents ])

需要添加限制查找的条件

:conditions=>["archived = '0'"]

虽然这不起作用

@employees = Employee.find_by_contents(params[:keywords].to_s, :include => [ :categories, :revisions, :approvals, :archives, :related_documents ], :conditions=>["archived = '0'"])

任何人都知道语法应该是什么？

Answer 1

如果你传递一个数组条件，我认为它需要是一个参数化的条件。尝试以下两种情况之一：

    @employees = Employee.find_by_contents(params[:keywords].to_s, 
                  :include => [ :categories, :revisions, :approvals, 
                                :archives, :related_documents ], 
                  :conditions=> "archived = '0'")

或

@employees = Employee.find_by_contents(params[:keywords].to_s,                           
                  :include => [ :categories, :revisions, :approvals, 
                                :archives, :related_documents ],
                  :conditions=>["archived = ?",'0'])

Answer 2

首先，你有什么错误？

试试这个

@employees = Employee.find_by_contents(params[:keywords].to_s, :include => [ :categories, :revisions, :approvals, :archives, :related_documents ], :conditions=>["employees.archived = ?", false])

Answer 3

有很多时间为ferret find_by添加一个条件，所以我添加了一个post命令来过滤它是否已存档。如果你想到更好的方式，请告诉我。感谢。

@employees = Employee.find_by_contents(params[:keywords].to_s, 
              :include => [ :categories, :revisions, :approvals, 
                            :archives, :related_documents ])
@employees = @employees.find_all {|p| !p.archived}

Rails：find_by_contents有条件;语法帮助请
