I agree with previous posts.
It might also be worthwhile to simplify your code to avoid unneeded

roof_age=requests.POST.get('roof_age'),
email=requests.POST.get('email'),

As a start, the logic checks for the model should not be in views.py but
rather with the model object (in models.py). You can extend the save()
method, for example, and add the checks there.

It fails because the second datetime in your test script is taken to be a

"NameError: name 'datetime' is not defined".
Try this instead:

The best approach is for the Django/DB devs to create these fields (and
forms) in advance for the users to enter data.
If you want users to add "key/pair" type data which is not known in
advance, look to adding a JSON column to your table; see:
https://www.postgresql.org/docs/14/datatype-json.ht
This seems to be referring to a Microsoft app

Obviously you will be searching in related table.
So if you have models.py like:
class Author(models.Model):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
class Book(models.Model):
title = models.CharField(max_length=200)
author = mod
#x27;admin:myapp_mymodel_changelist'))
i.e. if I comment out the import line the code works, otherwise it fails.
Any ideas on why Django is failing when importing from the app's admin?

You are better off using Django for what is it designed for - web-based
systems - and rather use other Python alternatives for desktop-based GUIs
e.g. pyQT
(see various resources such as

)

This seems to be an error raised by a third-party library; you'd probably
get a quicker / better response by contacting their devs.

There are numerous ways to design a front-end dashboard; this a highly
contested domain on the web!
Just some examples, using Django + various other tech are:

I would not assume what "previous" means. Rather use post_save to get the
actual ID of the current recording.

The suggested code will not work because, at this point, the "id" has not
yet been generated by the database (unlike the other data which is
typically entered by the user).
You will need to move this code to a post_save signal function -
https://docs.djangoproject.com/en/3.0/ref/signals/#post-s
While you cannot use Python operators and functions directly in the
templates, you can write your own "wrappers" around those you need:

Lots of examples out there, but here is one:

For working with static files (such as CSS or images), have a look at:

Its not clear what you mean by "last"; do you mean a record that already
exists in the database and has a ID value - or do you want the ID of the
current record? Either way, the code field should not be resetting the '0'
to a '1' as this is then misrepresenting the actual data.

I am not sure about the field names part, but you could probably create
that manually very easily.
For the data section, you need a list of lists, which you can get from code
like:
import json
data_ready_for_json =
list(mail_item_count_deliveries_perDate.objects.values_list('countDeliveries','
There are many things available "by default" in other frameworks; but
Django has chose to keep the core focused on doing key things well (I won't
say "simple"). For everything else, the plugin/app approach can be used to
support your project's specific needs.

Yes - short answer is you cannot really "protect" Python code directly
(see: https://python-compiler.com/post/how-to-distribute-python-program )
Long answer - don't sell your code to anyone that you do not trust with
it. Obviously, there is a legal route, but there is also the "name and
shame
>>> from django.apps import apps
>>> apps.all_models['app_name']
So if your app is called, for example, products, then:
>>> apps.all_models['products']
Will create a dictionary with all the model classes from that app.

Its not clear why you need JS at all. The app can load content from
directories on the server side (back-end) and write these to a DB. Django
could then load these from the DB and show in the normal way. Page
generation can be done via normal views (Django/Python code).
