Hello,
I recently updated an app:
Since web2py Version 2.19.1-stable+timestamp.2020.03.21.13.06.49 and Python
3.6.8
A web2py latest version in Master at the end of 2021 (Version
2.21.2-stable+timestamp.2021.10.15.07.44.23) and python 3.8
Everything seemed to work perfectly.
Now I have noticed that the forms with 'upload' fields are not working
well. Actually the form seems to work fine and what doesn't work is the
download of the image.
The problem only occurs when I have the following in the routes.py file:
routers = dict(
BASE=dict(
default_application='myapp',
),
)
In this situation, all requests for uploaded images return a 400 Bad
Request error.
*With almost all jpg files I have problems, but for example if the image is
called ff.jpg it works fine...*
I have traced the error to the file gluon.rewrite.py line above line1221:
def validate_args(self):
"""
Checks args against validation pattern
"""
for arg in self.args:
if not self.router._args_match.match(arg):
raiseHTTP(
400,
THREAD_LOCAL.routes.error_message % "invalid request",
web2py_error="invalid arg <%s>" % arg,
)
If I delete the routes.py file everything works fine. But I need myapp as
the default app.
Example of the problem with a clean install downloaded from github:
models
db.define_table(
't_upload',
Field('f_upload_img', 'upload'),
)
Controller upload.py
def upload_img():
record = db(db.t_upload).select().first()
form = SQLFORM(
db.t_upload,
record,
upload=URL('default', 'download')
)
if form.process(keepvalues=True).accepted:
redirect(URL())
return dict(form=form)
*With myapp as default application*:
http://127.0.0.1:8081/upload_img
seems to work, but
http://127.0.0.1:8000/download/t_upload.f_upload_img.bba19b6c318b6379.YmwxNTYxODI5Mzg3MTkzNi5qcGc=.jpg
*returns 400 bad request*
*Deleting router.py*
http://127.0.0.1:8000/pyapp/upload/upload_img
works fine and
http://127.0.0.1:8000/pyapp/default/download/t_upload.f_upload_img.ae2d38ca06c81a3d.YmwxNTYxODI5Mzg3MTkzNi5qcGc=.jpg
*returns the image*
Has anyone had this problem?
