推荐答案

尝试在表单中指定小部件，如以下示例所示：

Try specifying widgets in the form, as in the following example:

models.py

class Photo(models.Model):
    caption = models.CharField(max_length=80)

py

class PhotoAdmin(admin.ModelAdmin):
    list_display = (u'preview', u'caption')
    search_fields = (u'caption')
    form = forms.PhotoAdminForm

forms.py

class PhotoAdminForm(forms.ModelForm):
    class Meta:
        widgets = { 'caption': forms.TextInput(attrs={'size': 80})}

另外，您可以使用以下内容：

As alternative, you can use the following:

forms.py

class PhotoAdminForm(forms.ModelForm):
    caption = forms.CharField(widget=forms.TextInput(attrs={'size':80}))
