Question

我正在使用Forms.Modelform创建一个表单。我的表单中有四个下拉字段（BLOCK_CODE，PANCHAYAT_CODE，OFFICER_DESIGNATION，ACTIVE_OR_NONACTIVE），这些字段通过在模型表单中通过视图传递的参数来进行过滤。直到这里一切正常。我的表单是用所需的字段和值创建的。现在，当我请求发布方法时，我的表单在验证时会失败。在命令窗口中打印表单（我已添加图片以供参考）后，我看到我的表单正在传递所有下拉文件（BLOCK_CODE，PANCHAYAT_CODE等）的下拉列表中的所有可用值，即使在下拉列表中选择了值也是如此。由于我是django的新手，请帮助我所缺少的内容。我经历了很多关于stackoverflow可用的问题，但是找不到任何相关的解决方案。

我希望在发布请求时仅传递从下拉列表中选择的值

form.is_valid（）对于Django Foms的选择选项字段返回false
