通过Django管理站点添加数据时更改大小写(上/下)

如果您的目标是在“管理”部分保存时只将内容转换为大写,那么您需要 create a form with custom validation 要更改案例,请执行以下操作:

class MyArticleAdminForm(forms.ModelForm):
    class Meta:
        model = Article
    def clean_name(self):
        return self.cleaned_data["name"].upper()

override save 在模型字段中:

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)

文档中更新的示例建议使用args、kwargs传递为:

Django将不时扩展内置软件的功能 建模方法,添加新参数。如果使用*args,**kwargs 添加这些参数时自动支持这些参数。

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()

你必须 override save()

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()
