Charfield上升幅度

Question

我伸出UserCreationForm 並增加

username=forms.CharField(max_length=30,widget=forms.TextInput(attrs={'size':'80'})) 

但用戶名字段寬度保持不變。如何增加它？

Answer 1

嘗試在形式指定窗口小部件，如下面的例子：

models.py

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

admin.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})} 

作爲替代，你可以使用以下命令：

forms.py

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

Answer 2

由於1.7就可以解決這樣的：

admin.py

class PhotoAdmin(admin.ModelAdmin): 
    list_display = (u'preview', u'caption') 
    search_fields = (u'caption') 
    formfield_overrides = { 
     models.CharField: {'widget': TextInput(attrs={'size': '80'})} 
    }
