Before you can use Django, you’ll need to get it installed.

Or, you can write fixtures by hand; fixtures can be written as JSON, XML or YAML (with PyYAML install

Trigram similarity New in Django 1.10. The trigram_similar lookup allows you to perform trigram lookups, measuring the number of trigrams (three consecutive characters) shared, using a dedicated PostgreSQL extension. A trigram lookup is given an expression and returns results that have a similarity measurement greater than the current similarity threshold. To use it, add 'django.contrib.postgres' in your INSTALLED_APPS and activate the pg_trgm extension on PostgreSQL. You can install the exte

class RangeMinValueValidator(limit_value, message=None) [source] Validates that the lower bound of the range is not less than the limit_value.

class RangeMaxValueValidator(limit_value, message=None) [source] Validates that the upper bound of the range is not greater than limit_value.

class KeysValidator(keys, strict=False, messages=None) [source] Validates that the given keys are contained in the value. If strict is True, then it also checks that there are no other keys present. The messages passed should be a dict containing the keys missing_keys and/or extra_keys. Note Note that this checks only for the existence of a given key, not that the value of a key is non-empty.

class TrigramSimilarity(expression, string, **extra) [source] New in Django 1.10. Accepts a field name or expression, and a string or expression.
