Thanks!
The first part is working!!! The filename is as it is supposed to be!
This is my code at the Moment, maybe some can use it:
ltxfile = str(os.path.join(request.folder, 'tex', 'languages.tex'))
pdffile = str(os.path.join(request.folder, 'tex', 'languages.pdf'))
#------------------------------------
#Create and Close the TEX-File .......
#------------------------------------
os.system('pdflatex '+ltxfile) #create the PDF file
if os.path.isfile(pdffile): #remove old file from the tex directory
os.remove(pdffile)
os.rename('languages.pdf', pdffile) #move PDF file to the tex
directory
import cStringIO
pdfdata = open(pdffile,"rb").read()
response.headers['Content-Type']='application/pdf'
return response.stream(cStringIO.StringIO(pdfdata), attachment=True,
filename='languages.pdf')
elif form.errors:
response.flash = 'form has errors'
response.title = 'All Languages'
return dict(form=form)
The second Problem i didn't solve yet, i Need to make a refresh on my
sqlform.factory after the PDF file was displayed.
Thanks everybody for helping.
