基本上，我试图创建某种动态表单，并试图通过post请求更改CharField的值。简单地说，我的表单中有以下字段：
choice = forms.CharField(max_length=50)
在表单的init中，我有这样的内容：
for key, value in request.post.items():
if key == choice and value != :
self.fields[ choice ] = value
这显然不起作用，因为我正在为CharField（选项）分配一个字符串（值）。任何想法都将不胜感激。
您是否正在寻找类似http://jacobian.org/writing/dynamic-form-generation/？
在该示例中，它通过init添加了X个char字段
for i, question in enumerate(extra):
self.fields[ custom_%s % i] = forms.CharField(label=question)
应该能够对不同的表单字段进行额外扩展。
这取决于字段的值是什么意思。
如果您试图更改表单初始显示时显示的内容，则需要传递一个初始字典，其中包含与字段名称对应的键：
self.initial[ choice ] = myvalue
如果您试图更改传递到验证的内容，然后更改为cleaned_data，则需要更改data
self.data[ choice ] = myvalue
