Re: convert python 3 to python2

[Andréas Kühne]

Official access isn't denied - and python 2 will probably be available. The
problem is that you don't get any security fixes or any updates at all.
That in itself is a major problem. If someone is saying that you need to
use python 2, I would strongly recommend them to not even think about it.
All code that is written will be useless in a couple of years time, and
need to be updated or even worse thrown away.

Andréas

This is totally untrue. Yes, all code should be converted to py3, but
that is simply not happing at many companies. They will continue to
use their py2 apps, and either support them internally or purchase py2
support from one of the many companies offering it. Is that a good
idea? No, but it's a reality.

Re: convert python 3 to python2

[Deep Sukhwani]

Wow, TIL there are companies selling support for Python 2? Never heard of
it. So basically we are saying these companies will maintain there own
version of Python programming language which will continue to be maintained
as long as they have paid users for Python 2? I seriously doubt that. Or
may be I am understanding it all wrong.

Anaconda, Enthought, ActiveState, Red Hat and maybe others as well.
Also large companies can do their own support.

Re: convert python 3 to python2

[Deep Sukhwani]

Thanks for the prompt reply. Did a quick cursory check with Anaconda, I
don't think Anaconda does it. In fact Anaconda has posted a few months ago
about Python 2's EOL (End of Life) -
https://www.anaconda.com/end-of-life-eol-for-python-2-7-is-coming-are-you-ready/

Also, just did a quick look at their professional services, couldn't see
anything suggesting they will offer python 2 support beyond the python 2's
community itself.

Re: convert python 3 to python2

[Andréas Kühne]

Yes of course - I think RedHat will be continuing to support a python 2
environment because they haven't updated their own internal infrastructure
and also their distributions to python 3.

However - using one of those is still not very smart. The problem is that
all plugins have moved on. So Django, Flask, Numpy, Scipy, Mypy, Pypy and
so on are ported to python 3. The main argument still stands - why invest
money today into a language that is obsolete - and that you have had
several years notice to stop using? Porting to python 3 isn't that hard
either - there are a lot of tools to help you do that. I myself have ported
a website from python 2 to python 3, with tens of thousands rows of code.

So all you need to do is to set aside time to port the applications - and
if you don't do it now, you WILL need to do it later - that's a simple
fact. And then the code will be in the best case scenario obsolete, worst
case useless. I can't see one reason to invest a cent into writing python 2
code. I know that I am lucky to be able to define what I want to work with
and to set requirements and also have no legacy code. But even having
legacy code, it's just a matter of investing into your own application.

To say that it can't be done - look at Instagram - they did it with their
codebase, and I don't think that many of us are working on that size of
codebase.

Andréas

Django developer server auto quit when iterate QuerySet in template

[Huy Bùi]

Hello,

 Everytime i try to access a url, the Django developer server auto quit 
without any log about what happens.
 After debugging a little bit, i find out if i remove this block of code in 
the template file, i can access the web page normally:

 
 
 {% for d in departments %}
  {{ d.name }} - {{ d.department_code }} 

 {% endfor %}
 

 But i can iterate the QuerySet in the view normally, it seems like there 
aren't any problem iterating the QuerySet:

def edit(request):
departments = Department.objects.filter()
for d in departments:
print(d.id, d.name, d.department_code)

return render(request, 'edit/edit.html', {'departments': departments})

 I have no idea what is happening and it's driving me crazy. Any help would 
be appreciated. Thank you.

django.contrib.auth: Confusion about AuthenticationForm.confirm_login_allowed

[Christian Franke]

Hello,

I am a bit confused about the relation and separation of
responsibilities between `AuthenticationForm.confirm_login_allowed` and
`ModelBackend.user_can_authenticate`.

When `AuthenticationForm` is used together with `ModelBackend`, we will
never call `AuthenticationForm.confirm_login_allowed` for an inactive
account, because `ModelBackend.authenticate` will never return an
inactive user, as `ModelBackend.user_can_authenticate` will return
`False` for inactive users. So the error message "This account is
inactive." is never shown for this combination of Form and Backend, and
the error message will always be about an incorrect password.

When `AuthenticationForm` is combined with `AllowAllUsersModelBackend`,
`AuthenticationForm.confirm_login_allowed` will be called and raise a
validation error for inactive accounts, because they are returned from
the backend, leading to the error message "This account is inactive."

Given that `AuthenticationForm.confirm_login_allowed` exists the way
that it does, it seems like there are valid configurations in which the
form has the responsibility to determine the user's authorization to log in.

However, it seems quite dangerous to me to leave it up to the form to
deny login to users, e.g. because there might be other ways of
authentication that are not using AuthenticationForm.

So my question would be: Under which circumstances is it a good idea to
leave such authorization decisions up to the form/what setup did the
original authors have in mind when writing `confirm_login_allowed`?

All Best,
Chris

Re: Django developer server auto quit when iterate QuerySet in template

[Deep Sukhwani]

Possible to push the whole code to a Github repo so someone could check out
and try locally - Couldn't really figure out anything that might be going
wrong by looking at this much mode?

Also, just out of curiosity, why are you using *Department.objects.filter()*
instead of *Department.objects.all()* since you are anyways not passing
anything to the filter.

how to use django pagination with sql query and not ORM

[leb dev]

I now how to use django pagination with ORM django after filtering the 
required data and put in into *pagination div*

*queryset_list = employee.objects.all()*
*query=request.GET.get("q")*
*if query:*
*queryset_list=queryset_list.filter(*
*  Q(name__icontains=query)|*
*  Q(father_name__icontains=query)|*
*  Q(mother_name__icontains=query)|*
*  Q(content__icontains=query)|*
*  Q(create_date__icontains=query)*
*  # Q(user__first_name__contains=query)*
*).distinct()*


*paginator = Paginator(queryset_list, 5)*
*page_request_var = "page"*
*page = request.GET.get(page_request_var)*
*queryset = paginator.get_page(page)*

*context={*
*"object_list":queryset,*
*"title":"List Items",*
*"page_request_var":page_request_var,*
*}*
*return render(request,"blog/list.html", context)*


the above code is working 

my question is how to convert this ORM into raw SQL 

i know that i must use LIMIT and OFFSET  in raw SQL  to embedded into 
paginator.

Re: convert python 3 to python2

[Mike Dewhirst]

I think the original question was around backwards conversion of 3.x 
code to 2.7.


I don't know of course because all my efforts have been forwards but I 
believe the six module would be the easiest way backwards.


And I imagine you would simply run your unit tests in 2.7 and use the 
six utilities to correct errors. With a little luck that would 
simultaneously keep the codebase compatible with 3.x for the inevitable 
forward upgrade.


Just a thought

Mike

This is totally untrue. Yes, all code should be converted to py3, but
that is simply not happing at many companies. They will continue to
use their py2 apps, and either support them internally or purchase py2

Re: how to use django pagination with sql query and not ORM

[Deep Sukhwani]

Have you tried using the *.query* on Django's QuerySet (documentation: [1])

For example, if my QuerySet is:
*User.objects.filter(username__contains='alpha')*

I can obtain the underlying raw SQL Query using:
*print(User.objects.filter(username__contains='alpha').query)*
*>>> *print(User.objects.filter(username__contains='alpha').query)
SELECT `auth_user`.`id`, `auth_user`.`password`, `auth_user`.`last_login`,
`auth_user`.`is_superuser`, `auth_user`.`username`,
`auth_user`.`first_name`, `auth_user`.`last_name`, `auth_user`.`email`,
`auth_user`.`is_staff`, `auth_user`.`is_active`, `auth_user`.`date_joined`
FROM `auth_user` WHERE `auth_user`.`username` LIKE BINARY %alpha%

Virtual Environment error

[yasar arafath Kajamydeen]

Dear All,

Actually i forget my virtual environment name. So when i run  --  python 
manage.py  runserver   command its showing   error like this  .


ImportError: Couldn't import Django. Are you sure it's installed and 
available on your PYTHONPATH environment variable? Did you forget to 
activate a virtual environment?




Thanks in Advance.

Re: Virtual Environment error

[Deep Sukhwani]

Depending on how you installed *virtualenv* package and what you are using
to create and activate virtualenv you can determine the currently present
virtualenvs on your computer.


   - If you used *virtualenvwrapper* - use *lsvirtualenv*
   - Additionally, you can look in your Home Directory and search for a
   directory named .virtualenvs (Note there's a dot before virtualenvs) to
   see the list of all present virtualenvs
   - Finally, you can always just go ahead and create a new one - shouldn't
   take too much time
