*Sorry everybody but i need your help again.*
Here is my code:
def languages_pedit():
req_id=request.args(0)
form = SQLFORM.factory(
Field('sortpdf', 'string', label='Sort-by',
requires=IS_IN_SET(['ISO-Code','Description']), default='ISO-Code'),
formstyle = 'table3cols',
submit_button='Submit')
if form.process(onvalidation=languages_validate).accepted:
response.flash = 'Form Accepted'
redirect(URL('print_languages',args=request.vars.sortpdf))
elif form.errors:
response.flash = 'form has errors'
response.title = 'Languages'
return dict(form=form)
* #I tried this mk_pdffile(pdffile,'languages.pdf') but it did not work*
def mk_pdffile(pdffile,pdfname):
import cStringIO
pdfdata = open(pdffile,"rb").read()
response.headers['Content-Type']='application/pdf'
return response.stream(cStringIO.StringIO(pdfdata), attachment=True,
filename=pdfname)
@auth.requires_login()
def print_languages():
sortpdf=request.args(0)
if len(request.args):
import datetime
now = datetime.datetime.now().strftime("%Y-%m-%d %H:%M")
if sortpdf=='ISO-Code':
ORDERBY=db.allanguages.lang_iso
else:
ORDERBY=db.allanguages.description
records = db(db.allanguages.id>=0).select(orderby=ORDERBY)
ltxfile = str(os.path.join(request.folder, 'tex', 'languages.tex'))
pdffile = str(os.path.join(request.folder, 'tex', 'languages.pdf'))
with open (ltxfile, 'wb') as texfile:
.......................................
#Code to make my texfile....................
.......................................
texfile.write('\\end{document}\n')
texfile.close()
os.system('pdflatex '+ltxfile)
if os.path.isfile(pdffile):
os.remove(pdffile)
os.rename('languages.pdf', pdffile)
pdfdata = open(pdffile,"rb").read()
response.headers['Content-Type']='application/pdf'
return response.stream(cStringIO.StringIO(pdfdata), attachment=True,
filename='languages.pdf')
*This works fine but the code below does not get excecuted and my SUBMIT
Button stays pressed?*
return dict(redirect(URL('languages_pedit')))
--------------------------------------------------------------------------------------------------------------------------

*2)After displaying the pdf-file my SUBMIT Button stays pressed*
*3)Is there another way to excecute the response.stream, something like
