Rails 3.2將參數從一個控制器動作傳遞到另一個

Question

我試圖將參數(useremail,costprojects)從一個控制器動作傳遞到另一個控制器動作。

這裏是控制器代碼：

def pdfemail 
    costprojects = Costproject.find(params[:costproject_ids]) 
    useremail = current_user.email 
    CostprojectsController.delay.pdfemail2(params: { useremail: useremail, costprojects: costprojects }) 
    redirect_to :back 
    flash[:notice] = 'An Email containing a PDF has been sent to you!' 
    end 

    def self.pdfemail2 
    @useremail = params[:useremail] 
    @costprojects = params[:costprojects] 
    ... 

但是，我得到：

wrong number of arguments (1 for 0) 

延遲項目顯示：

object: !ruby/class 'CostprojectsController' 
method_name: :pdfemail2 
args: 
- :params: 
    :useremail: somebody@gmail.com 
    :costprojects: 
    - !ruby/ActiveRecord:Costproject 
     attributes: 
     id: 8 
... 

感謝您的幫助！

如果你想通過一些PARAMS同時重定向到另一個動作，使用的ActionController ::參數：

def search 
    redirect_to :index, params: { query: params[:q] } 
end
