我正在尝试以Django形式设置初始值，该视图在视图中会多次显示。
不幸的是，即使经过3个小时的搜索和调试，它最终还是像我尝试过的所有方法都无法正常工作一样。
我的表单用于创建链接到对话的消息对象（我正在构建一个聊天机器人应用程序），并且在我的对话模板中，我以表单形式显示每条消息以使其以后可编辑。
问题是表单的每个字段都设置了我传递给view.py中的message_values var内部的表单的默认值。例外一个：“ tag_list” CharField（请参见下文）
我不能使用ModelForm，因为一条消息由多个模型组成（q_reply_ *字段将在我的视图中创建QuickReplies（）对象，标签将创建多个Tag（）等）
我尝试过在创建表单时在视图中传递指定 initial = message_values 的数据，并通过 __ init __ 通过以kwargs获取值来设置值（就像我所做的那样）用于消息var），但它只是不想工作...
我在任何地方都没有收到任何错误，零警告，并且在调试时得到的确认是，我获取标签的ManyToMany充满了数据，因此我在 message_values ['tag_list']中传递了字符串不是空的，应该显示在我的模板中。
如果有帮助，我的项目将托管在Heroku上
非常感谢您对我的帮助！
