Question

我看了http://docs.djangoproject.com/en/dev/ref/forms/fields/

>>> class CommentForm(forms.Form):
...     name = forms.CharField(initial='Your name')
...     url = forms.URLField(initial='http://')
...     comment = forms.CharField()
>>> f = CommentForm(auto_id=False)
>>> print f
<tr><th>Name:</th><td><input type="text" name="name" value="Your name" /></td></tr>
<tr><th>Url:</th><td><input type="text" name="url" value="http://" /></td></tr>
<tr><th>Comment:</th><td><input type="text" name="comment" /></td></tr>

在我的情况下，我想在views.py中使用初始字段因为我的初始数据（myinit_data）我在views.py

中得到它

my forms.py

   #...
    class SendMailForm(forms.Form):
      to = forms.EmailField(initial=myinit_data, widget = forms.TextInput(attrs={'size': '50'}))
      subject = forms.CharField(widget = forms.TextInput(attrs={'size': '50'}))
      body = forms.CharField(widget = forms.Textarea(attrs={'cols': '50', 'rows': '10'}), required=False)

my views.py

  #....
    myinit_data = list_of_data_generated # for example [a@mail.com,b@mail.com,c@mail.com]
    form_sendmail = SendMailForm()

我如何从views.py初始化我的字段

谢谢！：）

Answer 1

如the documentation所述，您可以将初始数据传递给表单构造函数：

form_sendmail = SendMailForm(initial=myinit_data)

但是myinit_data必须是字典，键是字段名称。

在views.py Django中的Field.initial？
