原文 2020-11-19 18:50:39 1 1 django/ django-views/ django-forms

I am making a menu that goes through a few different steps.我正在制作一个经过几个不同步骤的菜单。 Select the grade, then select the textbook, then select the lesson.选择年级，然后选择教科书，然后选择课程。 I want to display the textbooks as cards with buttons that will bring the user to a view of all the lessons associated with that textbook.我想将教科书显示为带有按钮的卡片，这些按钮将使用户看到与该教科书相关的所有课程。 I've used session to go from the grade to the textbook, but I'm not sure how to go from the textbook to the lessons.我已经使用 session 从成绩到教科书，但我不确定如何从教科书到课程。 I think the way of getting there is to have the button change the session value to that textbook, and bring me to the view that will filter the lessons by that textbook, but I'm not sure how to do that.我认为到达那里的方法是让按钮将会话值更改为该教科书，并将我带到将按该教科书过滤课程的视图，但我不确定如何做到这一点。 Any suggestions would be welcome!欢迎大家提出意见！
