I've inherited a program that creates a PDF with information about a number
of servers.
Currently the program uses the subclass SimpleDocTemplate for creating this
report.
Because of the size of the report, I want to create a report per server.
My problem: creating the second document works fine, but the onFirstPage,
onLaterPages logic no longer recognizes separating the first page from the
later pages. The first report looks great, but all subsequent reports have
the cover page info overlaid on top of the first report page.
Forgive me, but I'm a bit new to ReportLabs functionality. How can I
"refresh" the environment to get each document printing with recognition of
the first page, later page logic?
My imports look like:
# ReportLab import statements
from reportlab.platypus import *
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib.units import inch
from reportlab.lib import colors
styles = getSampleStyleSheet()
Elements = []
Elements.append(PageBreak()) # So the title page is separate.
Title = 'vDASS Reports'
Title2 = "Bankers Life and Casualty"
arcane_dba = 'Jeff Wilgus'
arcane_email = 'jwilgus@dbacrew.com'
arcane_url = 'www.dbacrew.com'
sql = "select name from scheduler where scheduler_id = %s" %
(ID['Scheduler_ID'])
rs = vUtils.ExecSQL(sql, vUtils.db)
RptTitle = rs[0][0]
PrintTime = 'Generated: %s' % (DateTime.now().Format())
pageinfo = '%s / %s / %s' % (arcane_url, arcane_dba, arcane_email)
def myFirstPage(canvas, doc):
canvas.saveState()
canvas.setFont('Times-Bold',24)
canvas.drawString(108, 792-108, Title) #PAGE_HEIGHT-108,
Title)
canvas.drawString(108, 792-138, Title2) #PAGE_HEIGHT-108,
Title)
canvas.setFont('Times-Bold',16)
canvas.drawString(108, 792-216, RptTitle) #PAGE_HEIGHT-108,
Title)
canvas.setFont('Times-Roman',10)
canvas.drawString(inch, inch*0.75, PrintTime)
#PAGE_HEIGHT-108, Title)
canvas.drawString(inch, inch*0.5, 'First Page / %s' %
(pageinfo))
canvas.restoreState()
def myLaterPages(canvas, doc):
canvas.saveState()
canvas.setFont('Times-Roman',10)
canvas.drawString(inch, inch*0.5, 'Page %d - %s' %
(doc.page, pageinfo))
canvas.restoreState()
And the call to build each report is ...
def BuildTheReport(rlvl):
Elements.insert(0, Spacer(0, inch))
RunDate = DateTime.now()
if ID['Filename'] == 'Summary':
prefx = "Sum_"
else:
prefx = "Dtl_"
if rlvl == 1:
rptfile = '/var/www/html/%s%s.pdf' % (ID['Filename']
+ "_", RunDate.strftime('%Y%m%d'))
else:
rptfile = '/var/www/html/%s%s.pdf' % (prefx +
ID['SI_Name'] + "_", RunDate.strftime('%Y%m%d'))
doc = SimpleDocTemplate(rptfile,pagesize=(8.5*inch,
11*inch)) #, showBoundary=1)
doc.topMargin = 0.0
doc.bottomMargin = 0.75*inch
doc.leftMargin = 0.75*inch
doc.rightMargin = 0.75*inch
doc.build(Elements, onFirstPage=myFirstPage,
onLaterPages=myLaterPages)
return(rptfile)
