Django URL

URL Dispatcher

URL 패턴을 정의하고 해당 패턴이 일치하는 요청을 처리할 view 함수를 매핑

Variable Routing

URL 일부에 변수를 포함

Path Converters

URL 변수 타입 지정

• str - Matches any non-empty string, excluding the path separator, '/'. This is the default if a converter isn’t included in the expression.
• int - Matches zero or any positive integer. Returns an int.
• slug - Matches any slug string consisting of ASCII letters or numbers, plus the hyphen and underscore characters. For example, building-your-1st-django-site.
• uuid - Matches a formatted UUID. To prevent multiple URLs from mapping to the same page, dashes must be included and letters must be lowercase. For example, 075194d3-6885-417e-a8a8-6c931e272f00. Returns a UUID instance.
• path - Matches any non-empty string, including the path separator, '/'. This allows you to match against a complete URL path rather than a segment of a URL path as with str.
