About set context method

tip

Not to be confused with the {% set foo = "bar" ... %} expression in Jinja, which defines a variable. For examples of constructing SQL strings with {% set %} (and why {{ }} should not be nested inside quoted strings), see Don’t nest your curlies.

You can use the set context method to convert any iterable to a sequence of iterable elements that are unique (a set).

Args:

  • value: The iterable to convert (for example, a list)
  • default: A default value to return if the value argument is not a valid iterable

Usage​

{% set my_list = [1, 2, 2, 3] %}
{% set my_set = set(my_list) %}
{% do log(my_set) %}  {# {1, 2, 3} #}
Report incorrect code
{% set my_invalid_iterable = 1234 %}
{% set my_set = set(my_invalid_iterable) %}
{% do log(my_set) %}  {# None #}
Report incorrect code
{% set email_id = "'admin@example.com'" %}
Report incorrect code

set_strict​

The set_strict context method can be used to convert any iterable to a sequence of iterable elements that are unique (a set). The difference to the set context method is that the set_strict method will raise an exception on a TypeError, if the provided value is not a valid iterable and cannot be converted to a set.

Args:

  • value: The iterable to convert (for example, a list)
{% set my_list = [1, 2, 2, 3] %}
{% set my_set = set(my_list) %}
{% do log(my_set) %}  {# {1, 2, 3} #}
Report incorrect code
{% set my_invalid_iterable = 1234 %}
{% set my_set = set_strict(my_invalid_iterable) %}
{% do log(my_set) %}
