Symlink is another option... I had use symlink for a while for uploads
files as I was storing them on another system, so they were backuped and
reduced the size of my linux box... I stop doing it because there network
latency and the mount point was often down. But it works very well...

Hi Anthony,

Thanks for helping me solve the issue, I very much appreciate your help.


@richard.

Thanks for your reply, I had a look at bindfs, I work with Linux and had a
symbolic link on myapp/static/uploads I am not sure bindfs let me upload
files to myapp/static/uploads and store them in a directory structure
outside web2py.


Kind regards,

Annet

Re: [web2py] Re: uploadfolder outside web2py

[Richard Vézina]

You can also mount the directory you want you file in into web2py folder
with bindfs...

Or saying it differently mount a directory to another location...

https://bindfs.org/

But I think it would be only working with linux.

Good luck

[web2py] Re: uploadfolder outside web2py

[Anthony]

First, consider whether you really need a separate upload folder for each 
vertexID. The DAL already generates a unique filename for each upload, and 
the filename is stored in the database record, so you can always find the 
file by looking up the record.

If you need the separate folders, though, consider setting the upload 
folder with the model definition so you don't need to specify it separately 
in the SQLFORM action and so it will be easier to make use of the built-in 
response.download function:

IMAGE_FOLDER = os.path.join('/', 'Users', 'me', 'Documents')

db.define_table('mytable',
Field('image', 'upload', uploadfolder=os.path.join(IMAGE_FOLDER, 
'vertexID%s' % session.vertexID),
...)

Note, the folder path will end with "vertexIDNone" when there is no 
session.vertexID, but presumably that will not be an issue, as you should 
not be doing any uploads/downloads when there is no session.vertexID.

With the above change, you can then change the download function to the 
standard:

def download():
return response.download(request, db)

[web2py] Re: uploadfolder outside web2py

['Annet' via web2py-users]

Hi Anthony,

Thanks for your reply.

After reading the parts on download() in chapter 7 and 9 I wrote the 
following functions:

def logo():
vertexID = session.vertexID

table.vertexID.default = vertexID
folder = 'vertexID' + str(vertexID)
table.image.uploadfolder = os.path.join('/Users/iannet/Documents/' + 
folder)

record = table(vertexID=vertexID)

form = SQLFORM(table, record, deletable=True, showid=False,
   upload=URL('image_download', args=request.vars.image))

if form.process().accepted:
if record and form.vars.image__delete:
file = record.image
os.remove(os.path.join('/Users/iannet/Documents/' + folder, 
file))
elif form.errors:
get_flash(response, None, 'danger', 'error')
elif not response.flash:
get_flash(response, None, 'info', 'custom')

return dict(form=form)

def image_download():
folder = 'vertexID' + str(session.vertexID)
file_path = os.path.join('/Users/iannet/Documents/' + folder + '/')
return response.stream(open(file_path + request.args(0)))


Are there any improvements to make to this code?

web2py does not serve files by simply passing a filesystem path as a URL. 
If you are not storing the files in the application's /static folder, you 
must create an action within your app that serves uploaded files (see the 
/default/download action in the welcome app for an example) and specify the 
URL of that action as the "upload" argument.

[web2py] Re: uploadfolder outside web2py

['Annet' via web2py-users]

Thank you all for your replies,

This works :

table.image.uploadfolder = '/home/webapps/uploads'

to upload the images into separate folders I made the following adjustment:

folder = 'vertexID' + str(vertexID)
table.image.uploadfolder = os.path.join('/home/webapps/uploads/' + folder)


The problem is the image file doesn't display in the form:

form = SQLFORM(table, record, deletable=True, showid=False,
   upload=URL('home', 'webapps', 'uploads/' + folder, 
args=request.vars.image)) 


This buils the following source:

scr="/home/webapps/uploads/vertexID1/img_logo.image.bbaf6c..6e67.png"

Why doesn't the image file display in the form?

Also when I check the check to delete checkbox and submit the form the image
file isn't deleted.


Kind regards,

Annet

Also, unless it needs to be portable to other filesystems where the path 
does not start with "/home", you can simplify to:

table.image.uploadfolder = os.path.join('/', 'home', 'webapps', 'uploads')

or even just:

table.image.uploadfolder = '/home/webapps/uploads'

In addition to Stifan's remarks, I can attest that web2py can easily serve 
files outside of the web2py tree, although in my case those files aren't an 
upload field.

pls try:
table.image.uploadfolder = os.path.join(request.folder, '..', '..', '..', 
'webapps', 'uploads')

assuming there are folders:
/home/web2py/applications/adminmod
/home/webapps/uploads

according to your path, i think it just a little adjustment of parent 
folder ,'..', '..'
