Re: Django credit card redaction app - - MultiValueDictKeyError

[Ahmed Ishtiaque]

Hello drone4four,

Here are my opinionated responses on your questions.

1. What you have in your view is pythonic enough. That's the right way to
look up a value in a dict, and it's easy to understand. However, the way I
prefer to do things, I'd say that whenever someone enters a credit card
number, make a POST request to the view rather than a GET request. This
intuitively makes sense to me because I know for sure that the POST request
that's being parsed in a certain view should contain exactly the data I
want it to contain, rather than trying to figure out from a GET request
whether the data is present there. Also, since you're using an example
credit card app, I'd point you to paying attention towards your address bar
right after you make the GET request. It will contain the credit card
number in it. This can be a security issue when you're dealing with forms
in a practical sense with django. So, as far as I'm concerned, the more
"Django-esque" way is to make your credit card number submission a POST
request to the appropriate view.

2. As far as getting responses, I think it's always better the more code
you share for us to look at. For example, I just saw that you had a repo
setup for people to check out. I think that's a pretty good way to go. Of
course, if you have a private repo and don't want to give all your code
away, we understand that. In that case generally posting the code like you
did before should be fine and we'll try to help you out.

Hope your experience with django continues to be meaningful in the future!

Ahmed

Rename column headers with python DictWriter

[BIJAL MANIAR]

Hi,

Using Python DictWriter can we rename the column names?

Need to rename headers in CSV file so that output looks like. Basically 
need to rename database fieldnames like emp_name, emp_role to 
Name,Designation:
*Name, Designation*
ABC, IT
DEF, Admin

I am using Python DictWriter in django view and below is the snippet:

def export_csv(request):
data = [
{'emp_name': 'ABC', 'emp_role': 'IT'},
{'emp_name': 'DEF', 'emp_role': 'Admin'}
]
response = HttpResponse(content_type='text/csv')
response['Content-Disposition'] = 'attachment; filename="export.csv"'

*fieldnames = ['emp_name', 'emp_role']*
writer = csv.DictWriter(response, fieldnames=fieldnames, 
extrasaction='ignore')
writer.writeheader()
for row in data:
writer.writerow(row)
return response



Thanks,

Bijal

test if model object fits into QuerySet without executing SQL?

[Thomas Klopf]

Hi all,
  Please I have a question, couldn't find any answer for it..

  Let's say I have 2 QuerySets:
  1) Select all records from table
  2) Select all records from table where color = "blue"

So QuerySet #2 is more restricted than QuerySet #1

So question is - if I get a model object from QuerySet #1, is it possible 
to check if the model object is 'filtered'  or fits into QuerySet #2, 
without actually executing the SQL for QuerySet #2 to find the record again?

I'm asking because running the SQL for QuerySet #2 is expensive, ideally 
would test if the record fits into the QuerySet in purely python/django.

Thanks in advance!
Tom

Re: test if model object fits into QuerySet without executing SQL?

[jgibson]

Tom,

Could you clarify "fits into"?

qs1 = Table.objects.all()
qs2 = Table.objects.filter(color='blue')


mo1 = qs1[0]


Are you trying to determine if mo1 is in qs2?

Best

Re: test if model object fits into QuerySet without executing SQL?

[Phako Perez]

You can create query as

def get_query(value=None):
if value:
  query = “select all records from table where color = ‘" + value + “‘
  query = “select all records from table”

return query

Re: Looking for a Django co-founder

[Ruben Alves]

Hi Zack

I see you sent a similar email like a month ago (or at least was another 
user with the same idea)

Back then I didn't reply, but one month later I see you are still talking 
about that, so you seem to be persistent, which I believe is the key for 
success.

I have been working with Django and AWS for some years already, although 
never with React.

I'm available on this WhatsApp number: +353 089 977 3398

I am working on some migration code, and I did not enter the _id suffix to my 
field name in the RunSQL code. Django was very kind to give me the clue to 
reference the column with the _id suffix. That is an amazing hint, and it 
helped significantly. Thank you so much!

413 Payload Too Large on Django server

[nate]

Hey Django experts!

My team has been getting 413 errors whenever we try and upload large files 
to our Django back-end: 413 Payload too large

We can't exactly pin down the maximum acceptable file size - it seems to 
vacillate in the 1-3MB range.

Things we have excluded:

   - 
   
   It's not a webserver configuration issue, because we're running the
   Django server locally (without a webserver)
   - 
   
   We believe it's not an app server configuration issue, because this 
   happens on multiple app servers (./manage.py runserver and daphne -p 
   8000 topknott.asgi:application)
   - 
   
   It's not an issue with the field on the Django model, which looks 
   normal: photo = models.ImageField(blank=True)
   
Can anyone spot what we're missing?

rsync vs git for Django development? + Project directory location?

[drone4four]

Have two questions.

To manage development of a Django project, when interfacing local changes 
and mirroring them to my remote webserver, would you people recommend using 
rsync or git? I have a little experience with both. I've been using rsync 
to mirror basic HTML and CSS changes from my local host to my remote Apache 
public_html directory for a while now. I was thinking of using rsync for 
transferring changes to my webserver but in one of the courses I am taking, 
the instructor uses git and GitHub. I’m not sure if using git is overkill 
or not best practices. What would you people recommend?

Whether I go with git or rsync, I also need to make a decision about where 
to place my Django project folder on my VPS. One of the guides I am using, 
titled, “How To Set Up Django with Postgres, Nginx, and Gunicorn on Ubuntu 
18.04 
”
 
suggests putting it inside the user’s home folder. I gather this isn’t the 
most secure option. It’s also not a good idea to place the Django project 
folder inside the Apache public_html folder, am I right? I read both these 
things somewhere a while ago but I can’t recall exactly where. Anyways, to 
set the record straight, where would you people recommend I place my Django 
project folder on my VPS?

Separating remote vs local settings.py parameters - - “EMAIL”?

[drone4four]

If you take a look at this gist provided by a Udemy instructor and at this 
specific location 
,
 
here he wisely recommends separating important local development 
configuration parameters, such as SECRET _KEY. Of course everyone knows how 
stupid and foolish it would be to share the SECRET_KEY publicly on GitHub 
and then to use it in your production environment. 


So here is the list of parameters to place in the separate remote 
settings.py as it appears in that gist linked to above:


   - 
   
   SECRET_KEY
   - 
   
   ALLOWED_HOSTS
   - 
   
   DATABASES
   - 
   
   DEBUG
   - 
   
   EMAIL_*
   

If you look at the last one, it says: “EMAIL_*”. What do you people think 
the “_*” suffix? Is this standard for settings.py configurations? Or would 
you people think this is just a glaring typo on the side of the instructor?

Re: Separating remote vs local settings.py parameters - - “EMAIL”?

[Ahmed Ishtiaque]

The character "*" represents "wildcard". Here is the real reason why the
instructor puts it that way:
https://docs.djangoproject.com/en/2.1/ref/settings/#email-backend

There are a lot of variables that contain the 'EMAIL_' prefix, which is why
the instructor wrote it that way.

Re: rsync vs git for Django development? + Project directory location?

[Bill Freeman]

I'm sure that you'll get many opinions, but:

I've had success with git, presuming that filesystem space is not very
tight on the remote server.  You arrange your deployment scripts to run on
the remote (there are several tools to help with that, or for small scale
operations, ssh in and run them directly.  These scripts do a pull from
your central git repository (if you've got that on something other than
your development box, such as github, then your code and version history
are now redundantly in 3 places, at least), and then check out the revision
that has passed continuous integration (you will want to eventually) and
code review (buddy up with someone in the same boat if need be - I don't
care how good you are, a second set of eyes is a treasure).  And if it
bombs, or a problem shows up, rollback to the previous version is just
another checkout, your typed commands being the only things that must cross
the network.  If you had migrations with the new version, you may have to
run reverse migrations (a DB backup on the remote or DB server just before
installing a update is a good idea).

As to the security of the user account on the server box, that depends on
whether the user does anything else, and how automagically someone cracking
your development box can leverage that into access on the server.  Worse
that having stuff in a random user account also used for other things is
having this stuff under root.  It means that you have to get into root way
too often, and also a bug that tries to blow things away has the root
access to do it.  I've often deployed with apache, and made the /www
directory belong to apache.  Nothing there is served by apache except by
being explicitly listed in the apache configuration, such as directories
for CSS and js that are populated by running django's collectstatic
management command, which your scripts should run, among other things,
after checkout of a different revision..  The project directory and
probably a venv directory are there for convenience, but can't be served by
apache.  I presume that Nginx is similarly competent.  It was used at a few
places I worked, but I didn't have to deploy it, so I've not learned the
details.
