[web2py] Re: can a filename be suggested in a custom Exporter class for a SQLFORM.grid?
Here is my solution, idk if this is corrent or not:
class CustomExporter(ExportClass):
label = ''
file_ext = ''
content_type = ''
file_name = ''
def __init__(self, rows):
super(CustomExporter, self).__init__(rows)
request = current.request
request.vars._export_filename = self.file_name or request.function
class ExporterPDF(CustomExporter):
label = 'PDF'
file_ext = "pdf"
content_type = "application/pdf"
def __init__(self, rows):
super(ExporterPDF, self).__init__(rows)
def export(self):
request = current.request
response = current.response
pdf = MyFPDF()
pdf.add_page()
pdf.add_font('dejavu','',
'/agis/static/fonts/DejaVuSansCondensed.ttf')
pdf.add_font('dejavu','B',
'/agis/static/fonts/DejaVuSansCondensed-Bold.ttf')
pdf.set_font('dejavu', '', 12)
filename = '%s/%s.pdf' % (request.controller,request.function)
if os.path.exists(os.path.join(request.folder,'views',filename)):
html=response.render(filename, dict(rows=self.rows))
else:
html=BODY(BEAUTIFY(response._vars)).xml()
pass
pdf.write_html(html)
return XML(pdf.output(dest='S'))
In this case is my own recipie for generic PDF exporting, using
view_file.pdf as a template and request.function as the default filename
for the exported file name.

[web2py] Re: can a filename be suggested in a custom Exporter class for a SQLFORM.grid?
on sqlhtml.py line 2394:
...
oExp = clazz(rows)
export_filename = \
request.vars.get('_export_filename') or 'rows'
filename = '.'.join((export_filename, oExp.file_ext))
response.headers['Content-Type'] = oExp.content_type
response.headers['Content-Disposition'] = \
'attachment;filename=' + filename + ';'
...
seems to be the code responsible for the download filename, and it is
trying to find a filename suggestion on *request.vars.get('_export_filename')
*!?
