Hi Anthony,
Thanks for the help.
The download_path variable doesn't change regardless of whether the
download() function includes, or is passed, the 'download_filename' arg.
Indeed, the file downloads successfully when the download function is the
default, ie -
def download():
return response.download(request, db)
..and when download() is called with just this one arg -
<td>{{=A('Download', _href=URL('default', 'download',
args=download_path))}}</td>
When I added the second parameter to the call to download()-
<td>{{=A('Download w title', _href=URL('default', 'download',
args=[download_path, 'new_title']))}}</td>
..I changed the download() function in the default controller to this-
def download():
return response.download(request, db, attachment=True,
download_filename=request.args(1))
The db field from the model looks like this-
Field('file', 'upload', length=128, autodelete=True,
requires=IS_NOT_EMPTY()),
It might be most telling to show the links that are generated in the view..
the [working] link for -
<td>{{=A('Download', _href=URL('default', 'download',
args=download_path))}}</td>
..looks like:
http://127.0.0.1:8000/test_app/default/download/main_db.file.b36e427143f2c727.64633532346236612d373033622d343235352d383330302d616362613637366136396262.txt
And the link for -
<td>{{=A('Download w title', _href=URL('default', 'download',
args=[download_path, 'new_title']))}}</td>
..looks like:
http://127.0.0.1:8000/test_app/default/download/main_db.file.b36e427143f2c727.64633532346236612d373033622d343235352d383330302d616362613637366136396262.txt/new_title
The latter generates the 404 error. As you can see, when I add the
'download_filename' arg, a new path is generated with the desired filename
appended to the path, which doesn't seem to make sense.
Thanks again for your help. Let me know if there is any more info I can
provide.
Cheers,
jl
