This isn't a complete answer, but I have this in one of my views:


*.odd  {background-color: #E5EECC}  /* light desert-y green */
*.odd  {background-color: #ddffcc}  /* light green-bar  */
*.odd  {background-color: #d0d0f0}  /* light blue grey  */




It's used in displaying a table, to give that lineprinter paper effect 
("green bar").  The order is significant; the last line overrides the other 
two; depending on my needs, I switch the order around to change the chosen 
color.

It's placed below the {{ extend layout.html }} line, so after all the css 
files have been read.  

For a dynamic situation, I'd make set up a css class, and then use 
javascript to add that classname to the td or tr element.

I suspect it does, without a space between dot and yew:  
"PyFileSystem.uploadfs".

I'm not a PyFileSystem user, but I bet you instantiate the file system, 
creating a directory object.  In the book, that last "uploadfs" would be 
the name of the directory object.  (And I suspect you can use different 
names if you want, as long as you match the Field's target and the 
directory object name.)

We'll see what the experts say, though.

[web2py] UnicodeDecodeError "'utf-8' codec can't decode..." when inserting a blob in database (python 3.6.3)

[alexandre . henry]

Hello All,

I'm an absolute newbie with web2py so I'm not sure if the issue lies in 
web2py/3.6 or my own mistakes... My apologies in advance.

I encounter this error in a db.my_table.update_or_insert(..)

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfe in position 96328: 
invalid start byte'


What I'm trying to do:
I have a text file that is the representation of a datamodel in a specific 
COTS format.
I want to parse it, list the tables to be created and create them actually.
I know that the file countains non-utf-8 characters, that's why I open it 
in binary:

   dpm_file = gzip.open(filepath,'rb')

... parse it using binary regex: (I imported the 'regex' module)
regexp = regex.compile(b':columns 
(\(((?>[^()]+)|(?1))*\))',regex.DOTALL)
header_classes = regexp.findall(one_format_text)[0]

... and insert the results in db blob fields: (the error occurs here)
db.dpm_header.update_or_insert(db.dpm_header.dpm == my_dpm_id, dpm = 
my_dpm_id, header_classes  = header_classes, header_objects  = 
header_objects)

I defined blob fields because I thought that it was the way to write 
directly in binary in database.
I really wanted to use binary preciselly to avoid to manage the 
encoding/decoding issues.

In addition, this project is an attempt to transport in web2py an older 
project that was working perfectly in pure python 3.6.3 (unix and windows) 
(except that instead of creating tables in a DB, I created text files in a 
filer...).
Is it a issue on web2py/python 3.6? Or my misunderstanding on database 
management...

Thank you for your help!

[web2py] Is there a typo !? uploadfs

[Yoel Benítez Fonseca]

h!

In the book, 
http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Field-constructor


Says:

"uploadfs allows you specify a different file system where to upload 
files, including an Amazon S3 storage or a remote SFTP storage. This 
option requires PyFileSystem installed. uploadfs must point to 
PyFileSystem. uploadfs



widget must be one of the available widget objects, including custom 
widgets,..."



At the end is 'must point to PyFileSystem.uploadfs' or 'must point to 
PyFileSystem' and the last '. uploadfs' don't belongs there ?



regards,
Yoel Benítez Fonseca
