What is the etymology of 'slug'?
In CouchDB definitive guide the author used key "slug" in a document.
{
"title": "Hello World",
"slug": "hello_world"
}
What does "slug" mean and why is it used?
回答1:
Slug is used to make a name that is not acceptable for various reasons - e.g. containing special characters, too long, mixed-case, etc. - appropriate for the target usage. What target usage means is context dependent, but in general case slug is a more appropriate combination of other fields. In the above case, only one field is used - title.
