Extend django-model-utils and django-extensions.

Version 0.4.0 code got deleted but still exists on PyPI.

• Serialized Number Generation (e.g. PN-0001, PN-0001; MY1, MY2)
  • NumberedModel
• Useful Model and Form fields
  • SimplePercentageField
• Several Useful Utility Functions
  • is_number: checks if number could be coerced to a float
  • ratio_to_whole: .1 to 10; useful for percentages to "human"
  • whole_to_ratio: 10 to .1; useful for "human" to "percentages"
  • perhaps others, see docs when they're published

pip install django-rubble

1. Clone the repository: git clone https://github.com/WoosterTech/django-rubble.git
2. Install the dependencies: poetry install

Simply use the functions, fields, models.

The biggest "gotcha" is that NamedSerialNumber needs to be imported in your urls.py file; not actually sure why, perhaps someone can help me with that?

To use the automatic numbering, subclass NumberedModel and make sure to include a number_config = SerialNumberConfig(...) attribute. It will set defaults, but just as a standard integer starting at "1" with no prefix.

class PartNumber(NumberedModel):
    name = models.CharField("Part Description", max_length=100)
    number_config = SerialNumberConfig(
        initial_value=10, prefix="PN-", width=4
    )

Numbers will be generated starting with "PN-0010" (note the padding to make a width of 4) and increment by the default step of "1."
