Changing case (upper/lower) on adding data through Django admin site
提问by Andor
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，我有点怀疑我应该怎么做，在通过管理站点添加数据时点击“保存”，所有内容都转换为大写...
Edit: Ok I know the .upper property, and I I 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，我知道该怎么做，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 validationto make the case change:
如果您的目标是在管理部分保存时仅将内容转换为大写，您将需要创建一个带有自定义验证的表单来更改大小写：
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 savein the model field:
如果您的目标是始终使用大写形式的值，那么您应该覆盖模型字段中的保存：
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 作为传递：
Django will, from time to time, extend the capabilities of built-in model methods, adding new arguments. If you use *args, **kwargs in your method definitions, you are guaranteed that your code will automatically support those arguments when they are added.
Django 会不时扩展内置模型方法的功能，添加新参数。如果您在方法定义中使用 *args、**kwargs，则可以保证您的代码在添加这些参数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()
回答by Javier
you have to override save(). An example from the documentation:
你必须覆盖 save()。文档中的一个例子：
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()
