Django Typeerror:\uuuu init\uuuu（）接受1个位置参数，但给出了2个。我已经看到了许多解决这个错误的方法，但没有一个与我的情况相匹配
我已经看到了许多解决这个错误的方法，但是没有一个与我的情况相匹配。我确信init类会得到多个参数，但我不知道如何解决这个问题 我的页面有一个下拉菜单。从下拉列表中选择值后，区域列表将以列表的形式出现。当我点击列表中的一个项目时，一个图表应该出现在同一页上。因此，我所做的是，我创建了一个初始表单（类MonthlySalesGraphs），填充后将呈现下一页，即view MonthlSalesGraphs_2，它与MonthlySalesGraph相同，但唯一的区别是它显示图形。但很明显，当这个错误突然出现时，这是不起作用的 回溯：Django Typeerror:\uuuu init\uuuu（）接受1个位置参数，但给出了2个。我已经看到了许多解决这个错误的方法，但没有一个与我的情况相匹配,django,django-rest-framework,Django,Django Rest Framework,我已经看到了许多解决这个错误的方法，但是没有一个与我的情况相匹配。我确信init类会得到多个参数，但我不知道如何解决这个问题 我的页面有一个下拉菜单。从下拉列表中选择值后，区域列表将以列表的形式出现。当我点击列表中的一个项目时，一个图表应该出现在同一页上。因此，我所做的是，我创建了一个初始表单（类MonthlySalesGraphs），填充后将呈现下一页，即view MonthlSalesGraphs_2，它与MonthlySalesGraph相同，但唯一的区别是它显示图形。但很明显，当这个错误
