Supposed for some reason our app need a full path filename (the name
itself, not necessary the content), currently we have only one way to
do that. We use a blank TEXT input field for user to type a long long
dir name such as "D:\Inside\a\deep\deep\dir\there\is\my\big
\datafile.iso". It is not user friendly.
The <INPUT type="file"...> almost does the job but it only provide the
file's basename i.e. "datafile.iso" in above example. (Perhaps I
should change my proposed name FILENAME_SELECTOR into
FULLNAME_SELECTOR.)
My above conclusion is gathered on Windows. Don't know whether Linux
or Mac has the same problem. However, the proposed FILENAME_SELECTOR
should work cross platform because it only depends on javascript.
Need an code example?
1) Put the class definition in my first post into a models/selector.py
2) write your controller:
def test():
form=FORM(FILENAME_SELECTOR(_name='fullname'),
INPUT(_type='submit'))
if form.accepts(request.vars):
return {'':request.vars.fullname} # Got a FULL path name
return {'':form}
This feature is useful if you are developing a file sharing system
based on web2py, which need to know the full path name for later
streaming. Or if you are developing a web-ui system to wrap all your
command-line tools, you also need the full path name for a os.system
(...) later.
