Django初学者在这里需要帮助！我正在尝试以模态形式上传图像，问题是我无法提交模态...当我单击提交按钮时，实际上什么都没有发生...在2天的苦苦挣扎中...我正在使用Bootstrap V 1.0.4从网络上尝试了一些JS代码，但没有一个对我有用...我知道该怎么办？谢谢...这是我的模态：

 <div id="myModal" class="modal fade" role="dialog">
                      <div class="modal-dialog">

                         <!-- Modal content-->
                        <div class="modal-content">
                          <div class="modal-header">
                            <button type="button" class="close" data-dismiss="modal">&times;</button>
                            <h4 class="modal-title">????? ???</h4>
                          </div>
                         <div class="modal-body">
                          <p>????? ????? ???? ??? ?? ????? ??? ?? ????? ??? ???? ??????:</p>
                             <ul>
                                 <li>?????? ??? ???? ???? ???? ???? ?????? 8 ??????? ?? ????</li>
                                 <li>???? ??? ?????? ????: jpg , Gif , PNG</li>
                                 <li>?? ???? ????? ??? ??? ????????? ??? ? ??? ??? ?? ??? ??? ????? ?????? ?? ? ?? ?? ??? …

我有5个班,Customer,Supplier,Order,Design和OutSource.它Order有3个关系,一对一Customer,多对多Design,一对一OutSourse.首先,我只是没有将其添加s one to one relationship with客户(customer=models.ForeignKey(Customer)), now I wanna add the those 2 relationships with设计andOutsourse`.

 design=models.ManyToManyField(Design)
 outSource=models.OneToOneField(OutSource)

当我这样做并运行"makemigrations"命令时,我收到此错误 - >"NameError:name"设计"未定义"没有那两行代码我可以迁移而没有任何问题...无法弄清楚哪里出错了 任何帮助将不胜感激.
