并添加到settings.py：

INSTALLED_APPS=[# Django apps'binhash',# Your apps]

兼容性

用法

只需导入并设置一些字段：

fromdjango.dbimportmodelsfrombinhashimport(MD5Field,SHA1Field,SHA256Field)classISOFile(models.Model):name=models.CharField('Name',max_length=30)url=models.URLField('URL')md5sum=MD5Field('MD5 Checksum')sha1sum=SHA1Field('SHA-1 Checksum')sha256sum=SHA256Field('SHA-256 Checksum')

然后，像使用charfields一样继续使用它们：

# Create normaly as if the fields were strings:ISOFile.objects.create(name='Ubuntu Server 17.04',md5sum='d02df11b4a7318b7250824f6d0bab9c0',sha1sum='bc5fb639724b5cd90eb739845f246e2c564b0dd8',sha256sum='632e64dde9a7da27fa96bea4d2cf78f0''51065c6becc0d0f728aabfc091396256')# Fetch by string is also supported:ubuntu=ISOFile.objects.get(md5sum='d02df11b4a7318b7250824f6d0bab9c0')# Everything works as expected on the application side:print(ubuntu.sha1sum)# Shows bc5fb639724b5cd90eb739845f246e2c564b0dd8print(type(ubuntu.sha1sum))# Shows <class 'str'>

如果您感到怀疑，请检查数据库：

$ ./manage.py dbshell
sqlite> .header on
sqlite> .mode column
sqlite> select hex(sha1sum) hex_sha1,
   ...>        length(hex(sha1sum)) size_if_this_was_varchar,
   ...>        length(sha1sum) actual_size
   ...> from downloads_isofile;
hex_sha1                                  size_if_this_was_varchar  actual_size
