Question

我目前正与调查应用程序上的两位同事合作，我们差不多完成了，但是我们遇到了一些我认为是常见问题的东西。

基本上，当一个用户与调查交互时，此操作将针对所有其他用户执行。 IE约翰击中了下一个，玛丽接下来，玛丽最终跳过了一个问题。这显然不是我们想要的。我们希望将问题对象彼此分开，或者将它们与帐户绑定，或者为每个帐户对象创建它们，以允许多个用户一次与调查交互，并且他们的操作/答案是互斥的。是否有一些通常的方式在rails中执行此操作，或者甚至称为什么？任何链接的材料都非常感谢。

class QuestionsBasicController < ApplicationController

@@a = 0

def index
    @b = @@a
    @userprojid = current_user.project_id
    @@compid= QuestionsBasic.connection.select_all("SELECT company_id FROM project WHERE ID ="+@userprojid.to_s)
    @@compid= @@compid.rows[0][0]
    @result = QuestionsBasic.connection.select_all("SELECT questiontxt FROM questions_basic WHERE company_id="+@@compid.to_s)
    @@fanarray = @result.rows
    @anarray = @@fanarray
end


def next
    @@a += 1
    @b = @@a
    @anarray = @@fanarray
    render "questions_basic/index"
end

def previous
    if @@a <= 0
        @@a = 1
    end
    @@a -= 1
    @b = @@a
    @anarray = @@fanarray
    render "questions_basic/index"

end
