[DCS] Split By First Line

The components is part of Content Settings Family and allows you to put a multiple values in one setting using a splitter defined in the first line of the

Overview

SplitByFirstLine

Split a given text value into multiple values using a splitter that is defined inside of the value. The result of splitting will be converted using type inside of the split_type attribute. Each value can be given under the same name suffix (but lowercased), but also the returned value can be chosen by the function split_default_chooser attribute. The first line will be used as a splitter if the value from the split_default_key attribute is in this line. It may sound confusing, but let me show you an example:

from content_settings.types.array import SplitByFirstLine

MY_VAR = SplitByFirstLine(
 split_default_key="MAIN",
 split_type=SimpleDecimal()
)

# now the variable will work as simple Decimal, with the extra suffix __main that returns the same value
# but if you update the value in admin to:
"""=== MAIN ===
10.67
=== SECOND ===
4.12
"""
# your variable will work a bit different
content_settings.MY_VAR == Decimal("10.67")
content_settings.MY_VAR__main == Decimal("10.67")
content_settings.MY_VAR__second == Decimal("4.12")

# the first line in the value === MAIN === defines the splitter rule, which means the following value will work the same
"""!!! MAIN !!!
10.67
!!! SECOND !!!
4.12
"""

It has a wide variety of attributes:

• split_type - the type which will be used for each value. You can use a dict to set a specific type for each key
• split_default_key - the key which will be used for the first line
• split_default_chooser - the function which will be used for choosing default value
• split_not_found - what should be done if the required key is not found. NOT_FOUND.DEFAULT - return default value, NOT_FOUND.KEY_ERROR raise an exception and NOT_FOUND.VALUE return value from split_not_found_value
• split_key_validator - a function that validates a key. You can use a function split_validator_in for the validator value
• split_key_validator_failed - two passible values SPLIT_FAIL.IGNORE(default) and SPLIT_FAIL.RAISE. What should the system do if validation is failed. SPLIT_FAIL.IGNORE - just use the line with an invalid key as a value for the previous key. SPLIT_FAIL.RAISE - raise ValidationError

SplitTranslation

same as SplitByFirstLine but the default value will be chosen based on current django translation django.utils.translation.get_language
