A euphemism is a word or phrase that substitutes for language the speaker or writer feels is too blunt or somehow offensive. When people die, we say, instead, that they have "passed away" or "met their maker" or "gone to sleep." And, at the silly extreme, a garbage collector is a sanitation engineer , a janitor is a custodial engineer . What the writer must guard against is the tendency of euphemisms not only to shield readers from harsh reality but also to obfuscate meaning and truth. The military is especially guilty of this: bombing raids become surgical air-strikes and armies become peace-keeping forces . Good writing tells the truth and tells it plain.
In ancient texts of Jainism, such as the Kalpa Sūtra the term Sati is found, and it means "virtuous woman".  Many texts include a list of sixteen Satis, ancient women that represent auspiciousness and virtue, names revered in the mythology of Hinduism as well.  The connotation of the term Sati , states M Whitney Kelting, means the same "virtuousness, chaste, dedication to her family" as in Hinduism, and in both cases, it is different from the associated practice called suttee during colonial British India.  Evidence suggests that there were instances of Sati practice (self immolation) by Jain women, including some in the 19th century.  In the Epigraphia Carnatica , two of the 41 cases of sati in the time period 1400 to 1600 CE are those of Jain women. The low numbers of Jains known to have committed sati suggests that the practice was uncommon within this community.  In Jainism, the alternate competing phenomenon of widows becoming nuns, after a husband's death, has been recorded. 
If get_internal_type() returns a string that is not known to Django for the database backend you are using – that is, it doesn’t appear in .<db_name>._types – the string will still be used by the serializer, but the default db_type() method will return None . See the documentation of db_type() for reasons why this might be useful. Putting a descriptive string in as the type of the field for the serializer is a useful idea if you’re ever going to be using the serializer output in some other place, outside of Django.
