Re: [web2py] Re: Looking for web2py developer for Italian small company

[Vlad]

I've used web2py happily until today, but seems need to switch to py4web :)

I've never looked into py4web; just saw msgs going back and forth about it. 

What's the best way to start? Any tutorials? Is there a book similar to the 
one on web2py? What's the home page (assuming it's separate from web2py 
itself)?

Re: [web2py] webp2y XML helper sanitize line breaks under python3.6

[Clemens]

Hi Chris,

thanks a lot for your help! But the problem still exists even replacing my 
str_replace routine by str.replace() as proposed by you. Yes, I had the 
same problem with line breaks crashing the view. And replacing the line 
breaks by  fixed it. But switching form python 2.7 to 3.6 raises the 
new problem that the sanitizer can't process -coded line breaks. 
Without sanitize=True (i.e. False by default) it also works with python 
3.6. But sanitize=True doesn't work for -coded line breaks under 
python 3.6. And this is the case only for line breaks, all other special 
character are no problem.

I really think, that the XML sanitizer under python 3.6 is the problem. Do 
you have an idea for a work around except of eliminating all line breaks, 
cause I can't do this?

Best regards
Clemens

 Hello!

 In my web2py app I’m processing a list of items, where the user can 
 click on a link for each item to select this. An item has an UUID, a title 
 and a description. For a better orientation the item description is also 
 displayed as link title. To prevent injections by and to escape tags in 
 the 
 description I’m using the XML sanitizer as follows:

 A(this_item.title, \
   callback = URL('item', 'select', \
  vars=dict(uuid=this_item.uuid), user_signature=True), \
   _title=XML(str_replace(this_item.description, {'\r\n':'', 
 '<':'', '>':''}), sanitize=True))

 Using Python 2.7 everything was fine. Since I have switched to Python 
 3.6 I have the following problem. When the description contains line 
 breaks 
 the sanitizer is not working anymore. For example the following string 
 produces by my str_replace routine is fine to be sanitized by the XML 
 helper under Python 2.7 but not under Python 3.6:

 HeaderLine1Line2Line3
>

 Sanitizing line breaks escaped by  is the problem with Python 3 
 (but not with Python 2). Everything else is no problem for the XML helper 
 to sanitize (e.g. less than or greater than, I need these, since if there 
 is no description it is generated as ).

 How can be line breaks sanitized by the XML helper running web2py under 
 Python3?

 Thanks for any support!

 Best regards Clemens

Re: [web2py] webp2y XML helper sanitize line breaks under python3.6

[Christian Varas]

Hi Clemens,

Replace can handle big text it does not matter if is 1 - 1000 lines or
more, It will replace all the occurrences in the text, also is faster.
chaining "replace" is more faster than other methods.

description = his_item.description.replace("\n","").replace("\r","
").replace("<","").replace(">","")
XML(description, sanitize=True)

or in one line

XML(his_item.description.replace("\n","").replace("\r","")
.replace("<","").replace(">",""), sanitize=True)


A(this_item.title, \
  callback = URL('item', 'select', \
 vars=dict(uuid=this_item.uuid), user_signature=True), \
  _title=XML(his_item.description.replace("\n","").replace("\r","
").replace("<","").replace(">",""), sanitize=True)

I had this issue with line breaks and XML helper also, the input containing
line breaks was breaking my view, and replacing the bad characters before
pass it to the helper fixed my problem.

Try in a console with a custom text and see the results.

Hope this helps
Cheers.
Chris.

[web2py] Re: special chars in view, utf8 issue ?!

[Clemens]

Hello Ramos,

since I can't see your screenshot, I have to guess. But in German we also 
our special characters and I encode these by the following procedure:

import re
> import sys
>
> def convert_special_chars(label):
> if sys.version_info[0]==2: # python 2.x
> label = label.decode('utf-8')
> label = cgi.escape(label)
> label = label.encode('ascii', 'xmlcharrefreplace')
>
> return label
>

Have a try! Hope it helps!

Best regards
Clemens

Re: [web2py] webp2y XML helper sanitize line breaks under python3.6

[Clemens]

Hello Chris,

thanks for your answer! But just kicking out all line breaks is a little 
harsh, since in my case the description is mostly a few lines long with 2 
or 3 paragraphs. And I had the problem already solved by this procedure and 
the call as described in my question:

def str_replace(string, replacement_dict):
> if not isinstance(string, str):
> string = str(string)
> pattern = re.compile('|'.join([re.escape(k) for k in 
> list(replacement_dict.keys())]), re.M)
> return pattern.sub(lambda x: replacement_dict[x.group(0)], string)
>

And this solution worked very well with python 2.7, having even line breaks 
in link titles. Then I moved to python 3.6 and the problem was there. Thus, 
I think, that the XML sanitizer under Python 3.6 is the problem, since it 
can't handle 

Do you have any other ideas?

Best regards
Clemens

correct model
db.define_table("apps",
Field("title"),
Field("icon"),
Field("bg"),
Field("url"),
format='%(title)s'
)
db.define_table('menus',
Field("visibleTo",'reference auth_group'),
Field("app",'reference apps'),
Field('content','list:string'),
Field('icon'),
Field('href'),
Field('indice')
)
db.menus.visibleTo.requires=IS_IN_DB(db,db.auth_group.id,'%(role)s',multiple

[web2py] cannot reference db.auth_group in model ?

[António Ramos]

Hello all i have a problem relating a record to auth_group records

creating in admin a new record in table menus, referencing one or more
auth_group record results in a record with None in visibleTo field.
Why ?
[image: image.png]
db.define_table("apps",
Field("title"),
Field("icon"),
Field("bg"),
Field("url"),
format='%(title)s'
)
db.define_table('menus',
Field("visibleTo",'reference auth_group'),
Field("app",'reference apps'),
Field('content','list:string'),
Field('icon'),
Field('href'),
Field('indice')
)
db.menus.visibleTo.requires=IS_IN_DB(db,db.auth_group.id,'%(role)s',multiple
=True)
Field('href'),
Field('indice')
)

Re: [web2py] webp2y XML helper sanitize line breaks under python3.6

[Christian Varas]

I had an issue with line breaks too, I remove lie breaks like this with
python 3.7

some_string = some_string.replace(“\n”, ””).replace(“\r”, ””)

XML(some_string, sanitize=True)

Cheers
Chris
