Overview

Use Calendar to control date fields.

  from collapsar.fields.Calendar import Calendar

Calendar('Name')

Make field

Collapsar will assume the field if you pass only pass 1 parameter. You can define the label and field name this way:

  from collapsar.fields.Calendar import Calendar

Calendar('Updated at', 'updated_at')

Fill method

Use fill to control the way the field will be assigned to the model. For example, to save it on another format.

  def fill(self, request, model: "Model"):
    """Fill the field"""
    setattr(
        model,
        self.attribute,
        datetime.strptime(request.input(self.attribute), "%Y-%m-%dT%H:%M:%S.%fZ"),

Format date

Use format_value to display the date on a different format.

  def format_value(self, value: "datetime"):
    """Format the value for display."""
    return value.strftime("%Y-%m-%d") if value else None
