在我的控制器破坏功能中,我想重定向到索引后,项目删除,我想传递一个变量,称为“checked”当重定向：
def destroy
@Car = Car.find(params[:id])
checked = params[:checked]
if @car.delete != nil
end
redirect_to cars_path #I would like to pass "checked" with cars_path URL (call index)
end
如何通过这个’checked’变量与cars_path,以便在我的索引函数我可以得到它？ (cars_path调用索引函数)
def index checked = params[checked] end
解决方法
如果你不介意在URL中显示的参数,你可以：
redirect_to cars_path(:checked => params[:checked])
如果你真的介意,你可以通过会话变量：
def destroy session[:tmp_checked] = params[:checked] redirect_to cars_path end def index checked = session[:tmp_checked] session[:tmp_checked] = nil # THIS IS IMPORTANT. Without this,you still get the last checked value when the user come to the index action directly. end
