Re: Troubling installing Python 3 on my iMac

[Alfredo Sumague]

the safest way to use the latest python version (python 3.7.3 is the
latest) is to create a virtual environment for python3, from there you
install the latest python version, or you can use brew command  to install
python3. You can also install anaconda on your mac.

Good luck.

WYSIWYG/Rich Text Editor recommendations

[Tim Johnson]

Using python 3.7.2 and django 2.1.5

Production is in Ubuntu 16.04 and prospective deployment is likely
to be CentOS with same python/django.

I'm a retired python developer.

I'd welcome recommendations and/or caveats regarding  a stable
WYSIWIG "plugin".

Much is available on google, but it is always edifying to hear
individual comments.

I currently publish on drupal using its ckeditor plugin. My common
method is to compose articles in LibreOffice, then copy and paste
into the editor. Works well, except that it IS drupal.

I'd like to recreate the same functionality with django. I will need
to be able to include embedded images.

TIA

Re: Troubling installing Python 3 on my iMac

[RLM]

I guess you installed Python3.7.2 or similar

If so you can call it in a terminal with python3 not just python. Open a 
terminal and type python3 it should start

python 7.n is the operating system version.
It is important to use pip3 and  use virtualenv to create the python 3 
environment.


use pip3 to install django in your environment.
When you look at tutorials in google or other specify python3 and >2018 
so you don't get out of date tutorials of which there are hundreds.


Cheers
Roger

class django(object):
def setup(self):
pass

Now django is defined and even has a setup method.

That should solve your issue. If not, consider adding a bit more context to 
your question.

Suggested model structure to achieve users selection of services/package

[Gavin Boyle]

I am building an application that offers different services, a user can
select and purchase specific needed packages. I want to know the best way
to create the model so that our users can select and once paid it sets the
service to active. I have one model that holds information about each
individual services which includes (Package Title / Description / Price ).
I need another model to handle what services are associated to each user
but I am unsure how to go about this.

I have created two models as shown below but unsure how I can accomplish
the above as I believe there is a better was to accomplish this.

# Model to store club information on what clubs have access to what packages
class ClubPackages(models.Model):

club_id = models.ForeignKey(ClubInfo, on_delete=models.CASCADE)
PACKAGE_STATUS = (
('0', 'Active'),
('1', 'Not Active')
)
player_register_package = models.CharField(default='1',
max_length=1, choices=PACKAGE_STATUS)
player_register_price = models.DecimalField(default=100.00,
max_digits=8, decimal_places=2)
player_register_expiry = models.DateField(default=timezone.now)
roster_package = models.CharField(default='1', max_length=1,
choices=PACKAGE_STATUS)
roster_price = models.DecimalField(default=50.00, max_digits=8,
decimal_places=2)
roster_expiry = models.DateField(default=timezone.now)
rent_a_pitch_package = models.CharField(default='1', max_length=1,
choices=PACKAGE_STATUS)
rent_a_pitch_price = models.DecimalField(default=100.00,
max_digits=8, decimal_places=2)
rent_a_pitch_expiry = models.DateField(default=timezone.now)
shop_package = models.CharField(default='1', max_length=1,
choices=PACKAGE_STATUS)
shop_price = models.DecimalField(default=50.00, max_digits=8,
decimal_places=2)
shop_expiry = models.DateField(default=timezone.now)

# Model to store our available packages
class OurPackages(models.Model):

title = models.CharField(max_length=50)
description = models.TextField(max_length=200)
price = models.DecimalField(max_digits=8, decimal_places=2)

def __str__(self):
return self.title

Re: Simplifying code with multiple loops and logic, into queryset aggregates

[Joel Mathew]

Thank you Matthew. Excellent advise as always. When I started off with this
project 5 months ago, I was a beginner to both django and python. I've come
a bit along the journey. That customer model is the first model I created,
and I was unaware of these conventions. By the time I realized that, the
project has branched into several apps, and the code now runs into
thousands of lines of code. I didnt change the naming due to fear of
breaking other code. :)

Nowadays I do it more "pythonically". Still, it's great to have people like
you offer excellent general advise to help budding enthusiasts!

Sincerely yours,

 Joel G Mathew

Re: More controls on createsuperuser

[Joel Mathew]

It's not the command that you should be worried about, but shell access to
your system. If your database server is secure, shell access is restricted,
and the server is also hardened reasonably, you should be relatively safe.

 So do not give an access to manage.py to users that are not supposed
 to. Problem solved for good.

Re: More controls on createsuperuser

[Mario R. Osorio]

You'd only need editing the already existing management command and remove
the possibility of using createsuperuser, but that is as useless as a
ceiling fan on a motor bike.as anyone that already has access to the
management code could just revert those changes. even continuing this

 Actually this user is either a valid su or you are in serious trouble
 because the security of your server sucks or you gave access to your
 project to the wrong person.

 So, no I don't think there is any point in doing so. Not because it
 can't be done but because it is both trivially useless.and uselessly
 trivial.

Re: More controls on createsuperuser

RE :"*someone could still run createsuperuser *"

How do you suppose this is going to happen unless they have access to your
system?

If you are really concerned about that?? django is basically a package.
Just find the source code for the creatsuperuser admin command and delete
that file if its the only command in that file ;-)
if not just delete that function only :) Its that simple.

But How will you create a superuser after deleting the command from the
django package??

One way to solve is write your own custom management command, create
superuser at the time of deployment and delete that custom command also.

I hope this solves your problemo :)
Cheers!

 All,

 Curious what people think about more thought and control going into who
 can run the createsuperuser method?

 For example say there's models that I don't want anyone to touch except
 myself as a superuser. Is it not plausible that even if I make a Django
 Group around that model that someone could still run createsuperuser and
 give themselves the ability to have full control?

 Wouldn't it make sense if some random developer were to run
 createsuperuser using django settings with any of the databases (as an
 example) that it prevent them if say that email isn't on say an internal
 list in the django admin of approved potential users?

 I see something like this being a good idea to prevent just anyone from
 getting full control over the site without it being specifically provided.

 Maybe there's something I'm missing something but been reading about
 third party options and more about what's there and I just feel there's a
 hole when it comes to who can create a super user account. Obviously you
 could have a script that you run to initialize who is a super user, what
 the groups are etc, but then you're basically recording personal
 information somewhere when that should only be typed in.

 Open to ideas and thoughts, mostly just curious what could be a good
 answer.

RE: Simplifying code with multiple loops and logic, into queryset aggregates

[Matthew Pava]

It was a little difficult to follow your message because the formatting is 
non-standard, but I think this might be what you’re looking for.
Also, you should try to follow more Python coding conventions: models start 
with an upper case letter. Variables start with a lower case letter.

And you probably want to use a QuerySet Manager on Customer. Maybe a query like 
this:
Customer.objects.annotate(is_admitted=Case(When(admission_set__discharged=False,
 then=True), default=False).distinct()


From: django-users@googlegroups.com [mailto:django-users@googlegroups.com] On 
Behalf Of Joel Mathew
Sent: Tuesday, April 30, 2019 9:22 AM
To: django-users@googlegroups.com
Subject: Simplifying code with multiple loops and logic, into queryset 
aggregates

My models:

class customer(models.Model):
cstid = models.AutoField(primary_key=True, unique=True)
insurance_number = models.CharField(max_length=100, blank=True, 
null=True)
name = models.CharField(max_length=35)
ageyrs = models.IntegerField(blank=True)

class Admission(models.Model):
id = models.AutoField(primary_key=True, unique=True)
clinic = models.ForeignKey(Clinic, on_delete=models.CASCADE)
customer = models.ForeignKey(customer, on_delete=models.CASCADE)
diagnosis = models.CharField(max_length=2000, default='', blank=True)
date_admission = models.DateTimeField(default=timezone.now)
ward = models.ForeignKey(Ward, on_delete=models.CASCADE)
bed = models.ForeignKey(Bed, on_delete=models.CASCADE)
discharged = models.BooleanField(default=False)
ip_number = models.IntegerField(blank=True)
ip_prefix = models.CharField(max_length=20, default='', blank=True)

My objective: Set a variable to a query filter, adding a property, 
'is_admitted' to the queryset, so that I can pass this query set to the 
template and use the property while displaying data.

Code:

def is_admitted(cust):
admission = Admission.objects.filter(customer=cust, discharged=False)
admission_results = len(admission)
if admission_results > 0:
return True
return False

my_q = or_q_if_truthfull(
cstid=HospitalID,
name__lower__contains=name.lower() if name else None,
ageyrs=ageyrs if ageyrs.isdigit() else None,
agemnths=agemnths if agemnths.isdigit() else None,
mobile__contains=mobile if mobile else None,
alternate__contains=alternate if alternate else None,
email__lower__contains=email.lower() if email else None,
address__lower__contains=address.lower() if address else None,
city__lower__contains=city.lower() if city else None
)
ORSearchResult = customer.objects.filter(my_q, linkedclinic=clinicobj)
cust_set = []
cust_admission_status = []
for cust in ORSearchResult:
cust_set.append(cust)
cust_admission_status.append(is_admitted(cust))
print(f"Customer name: {cust.name} Admission status: 
{is_admitted(cust)}")
cust_templ_set = zip(cust_set, cust_admission_status)

And in template, I will do:

{% for cust, status in cust_templ_set %}
{{ cust.name }} {{ status }}
{% endfor %}

I want to understand how I can convert my above code by generating an aggregate 
over the queryset, so that I can use a property of the query, and change the 
template code to the following, and avoid the loop in the view, and the zip. So 
that the template code becomes:

{% for cust in customers %}
{{ cust.name }} {{ cust.status }}
{% endfor %}

I am not sure whether I am making complete sense, and can explain further.

Templates expand into html. So you just write javascript like you normally
do. You call javascript from within your templates by using something like:

Re: DateTimeField is in UTC but need IST standards

[vineeth sagar]

whenever USE_TZ=True is enabled, the timestamp is stored as a UTC object.
This is standard practice, why?

https://docs.djangoproject.com/en/2.2/topics/i18n/timezones/

Go through this, more than once. It'll be helpful.

DateTimeField is in UTC but need IST standards

[Sampath Reddy]

Hey guys,

I am using DjangoRestFramework as tech stack to develop backend API points
for my application.

I have a model with field created = models.DateTimeField(auto_now_add=True)
in one of the models.

I am using mysql as backend db, now the problem I am having is I am not
able to figure out how the timestamp is being generated. timestamp is in
UTC.

But I want to store IST standards i.e TimeZone 'Asia/Kolkata'

I can confirm mysql database time settings and Django TimeZone settings are
working as expected i.e IST standards.

Kindly someone please help me in figuring how the timestamp is being
generated wen I am posting data to the table.

Thanks and Regards,
Sampath

Troubling installing Python 3 on my iMac

[James]

I downloaded the file from the python website and went through the entire 
installation process... accepting all of the default values.  However, when 
I went to my Terminal window and typed python, it still shows the older 
version:

Python 2.7.10 (default, Feb 22 2019, 21:17:52) 

[GCC 4.2.1 Compatible Apple LLVM 10.0.1 (clang-1001.0.37.14)] on darwin

What did I do wrong?  I need to get this all setup before I can start the 
Django tutorial.

Thank you!

Re: Django with Docker

[Andréas Kühne]

Hi Omer,

I deploy using the latest version of the 3.7 python docker image. Then we
add all of the requirements into the docker container - without a virtual
environment. Because the docker image will only run the django application,
there is no need for creating a virtual environment. If I need another
application I create another docker image.

Hope this answers your questions.

Regards,

Andréas

Re: More controls on createsuperuser

[Jani Tiainen]

I've have to agree that any attempt to limit superuser creation through
manage.py is wrong solution to wrong problem.

Even it's possible to attempt it it is as easy to circumvent.

So do not give an access to manage.py to users that are not supposed to.
Problem solved for good.
