[英]Changing case (upper/lower) on adding data through Django admin site
I'm configuring the admin site of my new project, and I have a little doubt on how should I do for, on hitting 'Save' when adding data through the admin site, everything is converted to upper case... 我正在配置我的新项目的管理站点,我有点怀疑我该怎么做,在通过管理站点添加数据时点击“保存”,一切都转换为大写...
Edit: Ok I know the .upper property, and II did a view, I would know how to do it, but I'm wondering if there is any property available for the field configuration on the admin site :P 编辑:好的我知道.upper属性,我做了一个视图,我知道怎么做,但我想知道管理站点上的字段配置是否有任何可用的属性:P
If your goal is to only have things converted to upper case when saving in the admin section, you'll want to create a form with custom validation to make the case change: 如果您的目标是在管理部分中保存时只将事物转换为大写,那么您将需要创建一个带有自定义验证的表单以使案例更改:
class MyArticleAdminForm(forms.ModelForm):
class Meta:
model = Article
def clean_name(self):
return self.cleaned_data["name"].upper()
If your goal is to always have the value in uppercase, then you should override save in the model field: 如果您的目标是始终将值设置为大写,那么您应该在模型字段中覆盖save :
class Blog(models.Model):
name = models.CharField(max_length=100)
def save(self, force_insert=False, force_update=False):
self.name = self.name.upper()
super(Blog, self).save(force_insert, force_update)
Updated example from documentation suggests using args, kwargs to pass through as: 文档中的更新示例建议使用args,kwargs传递为:
Django will, from time to time, extend the capabilities of built-in model methods, adding new arguments. Django将不时扩展内置模型方法的功能,增加新的参数。 If you use *args, **kwargs in your method definitions, you are guaranteed that your code will automatically support those arguments when they are added. 如果在方法定义中使用* args,** kwargs,则可以保证代码在添加时会自动支持这些参数。
class Blog(models.Model):
name = models.CharField(max_length=100)
tagline = models.TextField()
def save(self, *args, **kwargs):
do_something()
super(Blog, self).save( *args, **kwargs) # Call the "real" save() method.
do_something_else()
you have to override save() . 你必须覆盖save() 。 An example from the documentation: 文档中的一个示例:
class Blog(models.Model):
name = models.CharField(max_length=100)
tagline = models.TextField()
def save(self, force_insert=False, force_update=False):
do_something()
super(Blog, self).save(force_insert, force_update) # Call the "real" save() method.
do_something_else()
