I'm using Platypus (part of reportlab) to generate pdfs without
micromanagement of Canvas elements. reportlab's documentation was very
helpful to learn how to work with Paragraph, Table, Image, etc. Some code:
# views.py
@login_required
def view_pdf(request, experiment_id):
experiment =
get_object_or_404(Experiment.objects.filter(pk=experiment_id))
response = HttpResponse(mimetype='application/pdf')
filename = slugify(experiment.title) + '.pdf'
response['Content-Disposition'] = 'filename=' + filename
generate_pdf([experiment], response)
return response
# functions.py
def generate_pdf(experiments, output):
doc = SimpleDocTemplate(output, pagesize=A4)
Document = []
for experiment in experiments:
Document.extend(pdf_elements(experiment))
doc.build(Document)
pdf_elements is a function that adds bits and pieces... This is just an
excerpt:
def pdf_elements(experiment):
styles = getSampleStyleSheet()
Document = [Paragraph(escape(experiment.title), styles["Title"])]
Document.append(Spacer(1,50))
date = unicode(experiment.date.strftime("%B %d, %Y"))
Document.append(Paragraph("Acquired on " + date, styles["Normal"]))
date_now = unicode(datetime.now().strftime("%B %d, %Y"))
Document.append(Paragraph("PDF created on " + date_now,
styles["Normal"]))
Document.append(Spacer(1,10))
return Document
Read the Platypus documentation for many more elements and options.
These are my reportlab imports:
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer,
TableStyle
from reportlab.platypus import KeepTogether
from reportlab.platypus import Table as Platypus_Table
from reportlab.platypus import Image as Platypus_Image
from reportlab.lib import colors
from reportlab.lib.pagesizes import A4
from reportlab.lib.styles import getSampleStyleSheet
