This is a widget for decimal/money/currency fields on Geraldo Reports.

When you use Geraldo to write reports, decimal fields must be formatted using get_value lambda attribute, because ObjectValue doesn't know what mask you want to use.

With this widget, you just copy it into a common use Python file, import into your reports file and use it replacing ObjectValue on elements for fields you must be formatted as money format.

Example:

from geraldo import Report, ReportBand, ObjectValue
from utils.reports import DecimalObjectValue

class ReportCustomers(Report):
    title = u'Customers List'
    page_size = A4

    class band_detail(ReportBand):
        height = 0.5*cm
        elements = [
            ObjectValue(attribute_name='id', top=0.1*cm),
            DecimalObjectValue(attribute_name='salary',
                left=26.2*cm, top=0.1*cm, format='%0.03f'),
            ]
