[web2py] Re: s3fs uploadfs error saying file name cannot be string - must be unicode

[Leonel Câmara]

Well the error is pretty explicit. Convert path to unicode.

Instead of:

path='attachments.files.ad112b05475e6e3e.4c61632045766...e7669746174696f6e2028456e676c697368292e706466.pdf'

Use:

path=u'attachments.files.ad112b05475e6e3e.4c61632045766...e7669746174696f6e2028456e676c697368292e706466.pdf'

[web2py] Re: LDAP Authentication never work

[Leonel Câmara]

Note that your function is decorated with 

@auth.requires_login()

However you only change the authentication method to LDAP inside that same 
function, so before the function runs it will only have the regular login 
and will require it. You need to do that stuff before the controller 
function runs in a model file.

[web2py] Masking external url

[e27gis]

Hello,

I have a web2py portal that has several applications, some of them are just 
a redirection to external urls.

I would like to mask these urls (hide the true external url to the users) 
as if they are pure web2py applications, and also make impossible for the 
users so paste directly these links without logging in. 

Do you have an idea how I could do it ?

Thank you very much.

Best Regards.

Thierry

[web2py] Am I be able to use file with Rdata extension as my database?

[yifan li]

Hi everyone,

I'm new to Web2py. I have a project that I need to use a dataset that has 
been trained saved as 'train.Rdata' and some R code to make prediction. I 
have found that I can use rpy2 to embedded R code into python. But, is 
there any way would you recommended for me to use Rdata in web2py? Thank 
you!

[web2py] Re: s3fs uploadfs error saying file name cannot be string - must be unicode

[Leonel Câmara]

Again, your new error is pretty explicit boto was expecting a string in 
your access_key and found a tuple there. You probably used a tuple with 
your key and secret in aws_access_key instead of just the key. The secret 
should go in aws_secret_key.

You can use the fetch()  function to go external, and then turn around and 
send the response  as your response.  This may be a bit complicated if the 
external resource uses XSS, and getting all the javascript and cxx files 
lined up may be a pain.

Another option might be to use an iframe, but while I've examined iframes I 
haven't spent a lot of time at it.

[web2py] Re: s3fs uploadfs error saying file name cannot be string - must be unicode

[watr]

The solution was in the code I posted originally. I had commas at the 
declaration of the public and private key. After removing the commas I can 
now upload.

*Before:*
bucket = "pobook",
region = 'ca-central-1',
aws_akey = "##",
aws_skey = ""

*After:*
bucket = "pobook"
region = 'ca-central-1'
aws_akey = "##"
aws_skey = ""

[web2py] DAL with UploadFS = s3 Not working with Delete and Download

[watr]

Here is my code:
from fs_s3 import S3FS
import datetime

bucket = "pobook"
region = 'ca-central-1'
aws_akey = "##"
aws_skey = ""

myfs = S3FS(
bucket,
aws_access_key_id=aws_akey,
aws_secret_access_key=aws_skey,
region=region
)

db.define_table('attachments',
Field('name', 'string', requires=IS_NOT_EMPTY()),
Field('files', 'upload', uploadfs = myfs, autodelete=True)
)

However, the default SQLFORM.grid "file" link gives a local link, not a 
link to the S3 file, so it fails. I created a download button to get around 
this.

I am unable to use the "Delete" or default "file" download link in 
SQLFORM.grid.

[web2py] Classes: Iteration of Row Objects & Updating

[Mark Billion]

Ive checked the docs and am sure I am missing it, but can someone please 
confirm or deny: If I iterate a row class attribute via another class 
method, updates applied by that method will will update the underlying row 
attribute?

For example:

__init__:
 self.dbobj = db(db.foo.bar>0).select()

def abc:
 for x in self.dbobj:
 x.attribute = "a"

My question is whether the self.dbobj attribute characteristic is now set 
to "a" for all records until the object is either destroyed or reupdated.  
I know I could test it, but I was wondering if there was a definitive 
answer...

[web2py] include python libraries that needed in web2py app to distribute to another

[黄祥]

*ref:*
https://groups.google.com/forum/#!newtopic/web2py/web2py/_lNJg6XLl4c

*question:*
1. which folder that must be included in app modules/ (e.g. 
~/web2py/applications/init/modules) folder?
e.g.
$ ls -l ~/miniconda3/envs/python2
drwxr-xr-x  42 sugizo  staff  1428 May 21 07:28 bin
drwxr-xr-x  19 sugizo  staff   646 May 20 18:57 conda-meta
drwxr-xr-x  91 sugizo  staff  3094 May 20 18:57 include
drwxr-xr-x  92 sugizo  staff  3128 May 20 18:57 lib
drwxr-xr-x   8 sugizo  staff   272 May 20 18:57 share
drwxr-xr-x   7 sugizo  staff   238 May 20 18:57 ssl
2. what is the different above method with pip install python_packages or 
using pip install -r requirements.txt ?
3. or even with pyinstaller (not sure can work to bundle python libraries 
for *nix environment), comment ?

*ref pyinstaller:*
https://pyinstaller.readthedocs.io/en/v3.3.1/operating-mode.html

thanks and best regards,
stifan
