[web2py] Re: Error trying to go back to python 2 after testing python 3: TypeError: translate() takes exactly one argument (2 given)

[Massimo Di Pierro]

I am puzzled by this too. The error is not in web2py code. The error is in 
the string.py module.
Also in your json example you are getting unicode both in py2 and py3 
except py3 does not put the u'' in front of unicode strings because they 
are default.

[web2py] New User Install gets Error Mac OSX High Sierra

[OogieM]

Brand new user. Downloaded the Normal Users Mac version. UnZipped and tried 
to run web2py.app get this error with no other useful information. 

System is 10.13.6 High Sierra on an older iMac.

Never got the window to select a password or get started. I did verify that 
no other versions of web2py were present on the system.

Tried deleting everything and redownloaded it just in case but got the same 
error. 

Looked at Console but nothing listed web2py as a problem but I'm not 
skilled in reading console messages.

Suggestions as to what to try next.?

[web2py] How to easily implement another CSS-Framework

[Jay B]

Hello guys,

I'm trying to figure out how to include another CSS framework instead of 
bootstrap. But the fact that the layout.html and other files point to the 
bootstrap files makes it harder than I thought. 

I would like to test other CSS frameworks like Semantic UI or Bulma instead 
of Bootstrap and wonder how to do it best. Or am I forced to delete all CSS 
files and standard views?

I would be happy if you could help me and thank you in advance for all the 
tips.

Greetz
Jay

[web2py] Bugfixes for older versions of Web2Py?

[Bruno Heremans]

Something I didn't find in the documentation 
:
 
are important bugfixes applied to older versions? 

Bugfixes don't need to be applied to ALL other versions, but going back 1 
or 2 minor versions would be nice. When a Web2Py environment is fully 
integrated, updating the core is usually something that takes time... 

Is there an agreement or a rule on this?

[web2py] Beginner can't get past install

[OogieM]

New user trying to install web2py on Mac High Sierra 10.13.6

Downloaded the for users mav cersion, unzipped, verified I have python 
installed. I tried to run the web2py app and get a error message "web2py 
Error" 2 buttons, open console or terminate. Tried looking at the console 
but I can't see anything useful there. 

Not even sure how to debug this since I can't even get to the window asking 
to create the admin password or get the app to run.

[web2py] Re: Error trying to go back to python 2 after testing python 3: TypeError: translate() takes exactly one argument (2 given)

[Lisandro]

I've found the issue, it's not web2py related, sorry about that.

My web2py instance has several applications running, each one is attached 
to a domain.
I store a the map of domains:apps in a dictionary that I save to a .pkl 
file.
Then my routes.py reads that file and loads the map of domains:apps

I write the .pkl file like this:

with open('map.pkl', 'wb') as file:
pickle.dump(dictionary_map, file, protocol=2)

Notice I use protocol=2 because I want to be able to read/write the file 
with python 2 and 3.

In my routes.py I read the file like this:

map = pickle.load(open('domains_apps.pkl', 'rb'))

routers = dict(
BASE=dict(
default_controller='default',
default_function='index',
domains=map,
map_static=True,
exclusive_domain=True,
)
)



However, after writing .pkl the file with python 3 and returning to python 
2, my applications fail with the error reported in my first message. The 
error goes away if I replace the .pkl file with an old backup I had made 
before using python 2.

I have noticed that once the .pkl file is written with python 3, then 
reading it with python 2 and 3 throws different results:

*with python 3*:
>>> r = pickle.load(open('domains_apps.pkl', 'rb'))
>>> print(r)
{'prod.com': 'prod', 'test.com': 'test'}


*with python 2*:
>>> r = pickle.load(open('domains_apps.pkl', 'rb'))
>>> print(r)
{*u*'prod.com': *u*'prod', *u*'test.com': *u*'test'}


Notice that in python 2 reading the .pkl file (that was written with python 
3 using protocol=2) returns unicode strings. This doesn't happen in python 
3. But i'm not sure what protocol to use. 

I'll do some more tests and I'll post here whatever solution I can find. 
Thanks for your time!
Regards,
Lisandro.

[web2py] Password field getting cleared

[App Jar]

Is there a way to keep the auth password and password_two fields from 
getting cleared when the auth register form has errors in it?

Every time there is an error in my form both fields get cleared requiring 
the user to enter the password again twice, once for each field.

I can keep the password field with the following code, but since 
password_two gets generated automatically in Auth() I can't keep its value.

# Works for password field but no equivilant for password_two
if request.vars.password:
   db.auth_user.password.default = request.vars.password

[web2py] Error trying to go back to python 2 after testing python 3: TypeError: translate() takes exactly one argument (2 given)

[Lisandro]

I'm testing my web2py application to see what I need to fix in order to 
make it compatible with python3.
I'm using web2py Version 2.17.1-stable+timestamp.2018.08.06.01.02.56

My application has been running with python2 for a long time.
Yesterday I tried with python3 (setting up a virtual environment) and 
everything went ok.
But now *I can't go back to use python2*, any request to the application 
fails with this error:
