python-3.x - 如何设置表单的下拉选项并添加图片，而不是使用 Django 的通用列表

Question

我想在尝试提交表单时拥有用户的个人资料图片和数据库中的值。目前，表单只有一个下拉列表，列出了数据库中所有对象的 id，例如：

---

对象 (1) 对象 (2) 对象 (3) 对象 (4) 对象 (5)

我希望下拉列表具有：

用户名，个人资料图片（他们来自静态文件的实际图像），对象 1 的字符串（数据库中的实际内容） 用户名，个人资料图片（他们来自静态文件的实际图像），对象 2 的字符串（数据库中的实际内容）用户名，个人资料图片（他们来自静态文件的实际图像），对象 3 的字符串（实际在数据库中的内容）用户名，个人资料图片（他们来自静态文件的实际图片），对象 4 的字符串（实际在数据库中的内容）用户名，个人资料图片（他们的实际图片来自静态文件），对象 5 的字符串（数据库中的实际内容）

这是一些代码，我愿意接受任何 python 解决方案（crispy/widget/etc.）

User = get_user_model()

    description = forms.CharField(widget=forms.Textarea, label='Submit an Observation')
    class Meta:
        model = Observation
        fields = ('description',)
        exclude = ('user', 'status', 'activate_date', 'deactivate_date')
        
        #observation = forms.CharField(label='Observation', max_length=250)

    data_description = forms.CharField(widget=forms.Textarea, label='Data')
