Re: Using generators in Django

[Mohit Solanki]

If you only need to access object once while iterating then using iterators
 is a
better choice to reduce memory consumption, Generators won't help here as
soon this expression
```MyNeedsModel.filter(project_id=project_id).all()```  is evaluated the
all the rows will be fetched from the db at once and will be stored in the
queryset object, also about the code review comment, using generators won't
bypass django's inbuilt caching mechanism or something, I am not sure about
`integrator` maybe he/she meant `iterator`?

Using generators in Django

[onlinejudge95]

Hi Devs,

A quick question. I am using Django to schedule some commands to populate
my PostgreSQL(Apart from using it as a web framework). I am currently
fetching records from a particular table and for each of those records
doing some calculation and storing the processed data in some other
database. The skeleton code looks like this

```
...
def fetch_needs(project_id):
for item in MyNeedsModel.filter(project_id=project_id).all():
yield item
...

class Command(django.core.management.base.BaseCommand):
def add_argument(self, parser):
...
def handler(self, *args, **kwargs):
project = (args[0], args[1])
project_id = MyProject.filter(...).id
for need in fetch_needs(project_id):

```

I need to know whether the use of generators is correct here, in the sense
that would it have any performance issues. The point that I am having
trouble understanding is a comment on my code review.

Also don’t use generator you are bypassing django inbuilt caching
> mechanism. Using integrator it will create another list and get them one by

Any help would be appreciated.

Thanks,
onlinejudge95

I prefer PostgreSQL for many reasons but like any DBMS it is only as

What are additional precautions I must take to pass the audit for

Re: Renaming sequences

[Michael MacIntosh]

Hey Mike,

I'm not sure about your specific setup, but I assume you are using the 
django.contrib.auth user model and are moving it over to your own app, 
and you have your own userprofile model that links to it.  The user 
model in django.contrib.auth is a swappable model.  Basically meaning as 
long as it inherits from a base class (I believe BaseUser) and you 
configure your settings (AUTH_USER_MODEL) to look at it, you should be 
fine, as long as you get the user model via get_user_model.


A link to the documentation on this
https://docs.djangoproject.com/en/3.0/topics/auth/customizing/#referencing-the-user-model

The next section also goes into defining a custom user model.

But in short there should be no ill-effects if you do everything right .

Also if you are moving your own user model into your own app, I would 
recommend naming it something other than common, something containing 
auth, like "catapp_auth" so it is clear that your user models and any 
custom authorization / authentication happens in there.


Hope that helps!

Cheers,
Michael.

In an existing production Django project I have just converted 
auth.user into common.user and company.userprofile into 
common.userprofile.


Having gone through the migration process more or less unscathed the 
original sequences are owned by the renamed tables. Eg 
public.auth_user_id_seq is owned by public.common_user.id


Everything seems to work fine but my unit tests are playing up and 
error messages are showing the original (and still correct) sequence 
names. It would make much visual sense to me now and especially to the 
future me (or anyone else) if the sequences were renamed as well.


I know how I could do it but I just need to know if I should.

Thanks for any advice

Mike

Django formset, forms passing unique choices into a choicefield for each form

[Brad Allgood]

Initially posted on stack overflow:

https://stackoverflow.com/questions/59395761/passing-dynamic-choices-into-a-formset-unique-for-each-form

I am working on what I thought was a simple college football confidence 
pool. The concept is as follows:

   - Bowl Model: Model that stores information of each bowl game being 
   played this season
   - Team Model: Model for all the teams playing in a bowl with a foreign 
   key to the bowl

models.py

from django.db import models
from django.contrib.auth.models import Group, User

class Bowl(models.Model):
"""Model for Bowl Game information"""
name = models.CharField(max_length=200)
b_date = models.DateField(null=True, blank=True)
b_time = models.TimeField(null=True, blank=True)
tv = models.CharField(max_length=10)
location = models.CharField(max_length=200)

def __str__(self):
"""String for representing the bowl object"""
return self.name

class Team(models.Model):
name = models.CharField(max_length=200)
bowl = models.ForeignKey(Bowl,on_delete=models.SET_NULL,null=True)

def __str__(self):
"""String for representing the intermediate table"""
return self.name   

I'm attempting to create a page has a formset which allows the user to pick 
the predicted winner of each game. Therefore I constructed the following 
view to call the form and formset.
views.py

   def fs_test(request):

   bowl_list = Bowl.objects.all()
   bowl_len = len(bowl_list)
   bowl_data = []

   TestFormSet = formset_factory(TestForm, extra=0)

   for bowl in bowl_list:
  bowl_data.append({
  't_bowl': bowl.name,'t_user':request.user,'t_weight':1,
  't_winner':winner_data,
  })

   if request.method == 'POST':
   pass
   else:
   formset = TestFormSet(initial=bowl_data)

   context = {
   'formset':formset, 'bowl_data':bowl_data
   }
   return render(request, 'catalog/test_bowl.html',context)

The following form inherits pre-populated data via passing "bowl_data" in 
the "initial" parameter.
forms.py

class TestForm(forms.Form):
 def __init__(self, *args, **kwargs):
 super(TestForm, self).__init__(*args, **kwargs)
 self.fields['t_bowl'] = forms.CharField()
 self.fields['t_weight'] = forms.IntegerField()
 self.fields['t_user'] = forms.CharField()
 self.fields['t_winner'] = forms.ChoiceField(
 widget=forms.RadioSelect,
 required=True,
 choices=[(o.name, o.name)
 for o in Team.objects.filter(bowl__name__exact=self.t_bowl)]
 )

I believe pre-populating the t_winner choices are failing because using the 
self.t_bowl in the query is just a field reference not the name of the 
field. I don't know how to pass in the "bowl" name to the form query. Or 
maybe I pre-populate the "choices" in the view but I don't know how to pass 
a dict into it and reference the correct index.

I've done some reading on the get_form_kwargs, but I'm not clear on how to 
use it in this instance.

It's entirely possible I'm using the wrong data model for this task, 
however I've been stumped for a couple of day on this. It took me a while 
to even figure out how to pass in unique "initial" values for each form in 
the formset.

Any recommendations would save what little hair I have left. Thank you!

Django 3 + MySQL + User privilages in DB server

[Wojciech Jędrzejczyk]

I am going to create in Django new fornt-end (HTML + JS + CSS) to old 
application based on big MySQL database (lots of tables, views, stored 
procedures, logs, triggers and so on). I need to force Django to respect 
database privilage for each user. I know I can give in django some rights 
e.g. to the model or view but when I have table "customers" i want to give 
access to the user to few, selected customers from this table, not to all 
records. In another words: django has connection to MySQL by one django 
user and all users in django make operations on database tgough this django 
user. How can I force django to check user privilages in MySQL server ?

I have all the logic in database in stored procedures. I can add input 
parameter to each procedure {e.g. IN v_user char(50)} and django will call 
these procedures with this parameter. This will work very well but this 
solution does not provide security. I have invested a lot of time in 
learning django and I really like this framework. I have already prepared 
many html+css templates, I have bought theme from bootstrap. I am in the 
middle of my work but I cant continue until I find solution which will 
ensure that the user will have rights from the database.

Regards
Wojtek

Re: how to display the number of views of an article with django

[Binoy U]

Making the answer with the assumption that article is a modal.

You can add a field named count(PostiveIntegerField) and increment the 
count every time an article is viewed. I hope you have implemented article 
view as a DetailView or similar function view.

Re: how to display the number of views of an article with django

[Awa M. Kinason]

First, add a column on the article Model named "views_count" 

Then on the DetailView of the article, and on the GET method. add this:

   
article.view_count += 1
article.save()


# or  (asuuming you are using class based views)

self.object.view_count += 1
self.object.save()


 


The problem with this method is that view_count will be updated each time 
the same person routes to that view or refreshes the page. To avoid this, 
you can add a list of 
counted articles in session. Something like


if 'counted_articles' not in session:
   session['counted_articles'] = []


# new line 
if self.object.id not in session['counted_articles']:
   session['counted_articles'].append(self.object.id)
   self.object.views_count += 1
   self.object.save()




This will ensure that for each session, the article is counted only once. 

hope that helps, if you have any questions, feel free to post them below.

Necessary Precautions to be taken in Software to pass security Audit

[Balaji Shetty]

Good Evening


 One query raised. My project is Government and it must pass through
Security Audits. Company may be indian Government.

It was built in Django with Sqlite backend. It is hosted on Pythonanywhere.
90% work is accomplished in backend only.

Only report and graph display are in frontend.

My backend is Sqlite. Should I switch to Postgresql for security reason.


What are additional precautions I must take to pass the audit for Software
Approval

Is there any web site giving guidance.

Re: Django security releases issued: 3.0.1, 2.2.9, and 1.11.27

[אורי]

Django developers,

We use Django 2.1 and anyway I saw that Django expects each user to have
one email address, where on Speedy Net each user can have multiple email
addresses. So I had to override *def save* in *class PasswordResetForm* on
Speedy Net:

https://github.com/speedy-net/speedy-net/blob/master/speedy/core/accounts/forms.py#L228-L279

I also added logging info to let us know who used the password reset form
and who received the password reset link.

I also checked and I noticed that if I reset the password of u...@speedy.net,
the email is sent to u...@speedy.net instead of u...@speedy.net - the email
is sent to the email the user submitted instead of the email the user has
on the database. This is a mistake. So I also updated the email to be sent
to the email the user has on the database - but the one matching the user
input and not just the primary email. So if a user has 2 email addresses,
and one stopped working, he can reset his password to the second email
address too, even if it's not his primary email address.

I decided to keep using Django 2.1 since there is still not a solution to
our Hebrew translation problem which I wrote you about in November.

Here is the code we use now (after I updated it today):

class PasswordResetForm(auth_forms.PasswordResetForm):
@property
def helper(self):
helper = FormHelperWithDefaults()
helper.add_input(Submit('submit', _('Submit')))
return helper
