Without Django¶

This example is done without relation to Django querysets:

import os
cur_dir = os.path.dirname(os.path.abspath(__file__))

from reportlab.lib.pagesizes import A4
from reportlab.lib.units import cm
from reportlab.lib.enums import TA_CENTER, TA_RIGHT

from geraldo import Report, ReportBand, Label, ObjectValue, SystemField,\
    FIELD_ACTION_COUNT, BAND_WIDTH

class SimpleListReport(Report):
    title = 'Demonstration without Django'

    class band_page_header(ReportBand):
        height = 1.3*cm
        elements = [
            SystemField(expression='%(report_title)s', top=0.1*cm, left=0, width=BAND_WIDTH,
                style={'fontName': 'Helvetica-Bold', 'fontSize': 14, 'alignment': TA_CENTER}),
            Label(text="ID", top=0.8*cm, left=0),
            Label(text="Name", top=0.8*cm, left=3*cm),
        ]
        borders = {'bottom': True}

    class band_page_footer(ReportBand):
        height = 0.5*cm
        elements = [
            Label(text='Created with Geraldo Reports', top=0.1*cm, left=0),
            SystemField(expression='Page # %(page_number)d of %(page_count)d', top=0.1*cm,
                width=BAND_WIDTH, style={'alignment': TA_RIGHT}),
        ]
        borders = {'top': True}

    class band_detail(ReportBand):
        height = 0.5*cm
        elements = [
            ObjectValue(attribute_name='id', top=0, left=0),
            ObjectValue(attribute_name='name', top=0, left=3*cm),
        ]

Now the object class

>>> class MyObject(object):
...     def __init__(self, **kwargs):
...         for k,v in kwargs.items():
...             setattr(self, k, v)

Populating a list of objects

>>> objects_list = [
...     MyObject(id=1, name='Rio de Janeiro'),
...     MyObject(id=2, name='New York'),
...     MyObject(id=3, name='Paris'),
...     MyObject(id=4, name='London'),
...     MyObject(id=5, name='Tokyo'),
...     MyObject(id=6, name='Moscow'),
...     MyObject(id=7, name='Beijing'),
...     MyObject(id=8, name='Hamburg'),
...     MyObject(id=9, name='New Delhi'),
...     MyObject(id=10, name='Jakarta'),
... ]

Generating PDF...

>>> report = SimpleListReport(queryset=objects_list)
>>> from geraldo.generators import PDFGenerator
>>> report.generate_by(PDFGenerator, filename=os.path.join(cur_dir, 'output/without-django.pdf'))

The Result
