[web2py] encoding and decoding spaces in request.args
Hey, I am generating URLs on the go and then decoding when they are called by user. e.g. application/controller/funtion/foo/bar/. I encode foo and bar individually so that if they have spaces, they get encoded to %20 not _ which seems liked default. but when I decode it (After user calls it), web2py automatically decodes spaces into _ ,so I no longer know whether I had _ or spaces in the actual url. I want to override this default behavior of decoding to web2py. I have no idea how, any help will be appreciated. Thank you guys
[web2py] downloading a static file without streaming
Hello, I have searched a lot and also tried to forge this up but I could not locate or create functionality to download a file from the server; not stream, just normal download. response.download requires a database field and response.stream streams a file, it doesn't simple download it. (I might be confusing the difference between streaming and downloading). I tried to set chunk size in stream function more than size of file in an attempt to make it equal to download but it is not working. I am comparing it to a file hosted by SimpleHTTPServer of CPython. Any idea how can I do it? Is it about headers? Hasanat Kazmi +923464362473

[web2py:22511] Auth problem
Hi,
I am newbie to web2py. I am working on a project where multiple people
will have to get different type of authentication, (e.g. teacher and
student have different level of access to the system). Now the problem
is that I can not create different instances of Auth class, e.g.
autht = Auth(globals(), db)
autht.settings.table_user = db.define_table('teacher',
db.Field('first_name'),
db.Field('middlename'),
db.Field('last_name'),
db.Field('specialization'),
db.Field('highestdegre'),
db.Field('housenum'),
db.Field('streetnum'),
db.Field('area'),
db.Field('city'),
db.Field('country'),
db.Field('phone'),
db.Field('email',
requires = [IS_EMAIL(),
IS_NOT_IN_DB(db,'teacher.email')]),
db.Field('username'),
db.Field('password', 'password', readable=False, requires=CRYPT
()),
db.Field('registration_key', length = 128, writable = False,
readable = False, default = ''),
db.Field('createdon', 'date' , default = now),
#db.Field('controller', db.controller)
)
autht.define_tables()
work seamlessly well but when I create another one, no matter which
one is defined first it throws error, e.g I created following:
authc = Auth(globals(), db)
authc.settings.table_user = db.define_table('controller',
db.Field('first_name'),
db.Field('middlename'),
db.Field('last_name'),
db.Field('phone'),
db.Field('email',
requires = [IS_EMAIL(),
IS_NOT_IN_DB(db,'teacher.email')]),
db.Field('username'),
db.Field('password', 'password', readable=False, requires=CRYPT
()),
db.Field('registration_key', length = 128, writable = False,
readable = False, default = ''),
db.Field('createdon', 'date' , default = now)
)
authc.define_tables()
this gives me following error:
ProgrammingError: (1146, "Table 'web2py.controller' doesn't exist")
does this error mean that web2py didnt find controller table in db,
isnt it supposed to make it itself?
