Re: Negative Stock Prevention

I don't think you need that constraint after using the PositiveIntegerField .

Re: Deploy Django Project in AAPanel

Hi Javier,

This doesn't sound like an issue with Django.

Try raising a ticket on AAPanel GitHub repo with a full error message and steps to reproduce it.

Bug with Watchman on Windows

Hello All,

Apologies if this is the wrong place to submit this. I couldn't find clear enough documentation on where to do this, so I guess I ended up here.

I installed pywatchman along with FB's watchman expecting StatReloader to change to WatchmnaReloader. Sadly, I was mistaken.

Python version: 3.9
Django version: 4.1
pywatchman version: 1.4.1
OS: Windows 11
PyCharm version: 2022.2.1
conda environment

Steps to reproduce:
Install Django
Install pywatchman
Install Watchman
Confirm Watchman is running
Start a django project
run: python manage.py runserver

I tracked the issue down to django.utils.autoreload.py. It seems that on client.capabilityCheck(), optional is a keyword argument set equal to None (optional=None), which is a problem because later when pywatchman call capabilities.synthesize() in pywatchman.capabilityCheck() (line 1079), it doesn't work because a for loop gets called on optional that was passed in. In Python for x in None: does not work. Could we get a kwarg added optional = [ ] in the function call for result = cliient.capabilityCheck() on line 628 in autoreload.py? I was able to sidestep the issue by inserting version = (4, 9) above line 627 where the try:...except:... is initialized in check_availability and then commenting out lines 627–632—try:...version = get_vers....

I know that then it won't provide the correct Watchman version, but it would be nice if it worked out of the box like it is supposed to.

Please let me know what further steps I should take to make sure that watchman works out of the box like it is supposed to.

Thanks,

David V.

Re: Negative Stock Prevention

Hello,

Sorry for the late reply.

I changed the models as below and added checkConstraint , But when I migrate I get the below error.

What am I still doing wrong?

class Stock(models.Model):
    quantity = models.PositiveIntegerField(default='0', blank=True, null=True)
    reorder_level = models.PositiveIntegerField(default='0', blank=True, null=True)

class Meta:
        CheckConstraint(check=Q(quantity__gt=0), name='quantity')

I don't see where you define the quantity variable, should that be instance.quantity? Also, presumably you want to check if quantity is greater than or equal to qu rather than 0.
Try changing `if quantity > 0` to `if instance.quantity >= qu`

Maybe change quantity and reorder_level to PositiveIntegerField?

Re: What do you do with large project and forms?

You need to work with model forms, but not forms, in your templates implement crispy forms  to avoid over coding

1. Create a forms directory
2. Create ../forms/__init__.py
3. Move your forms.py into the forms directory
4. In ./__init__.py write from .forms import (

  EtcForm,
)

This gives you unchanged forms calling from wherever ... from appname.forms import etc

5. When all that is working split your 3k forms.py into appropriately named smaller files each containing the form class or classes you prefer and adjust the ./__init__.py imports accordingly

You might encounter occasional circular imports but you should get the hang of it soon enough.

ASP.net isn't a programming language, so you should probably start by
learning what a programming language is before attempting to learn to
use one.

Additionally Django is very much a backend framework so your question
doesn't make any sense.

Kind regards,

Re: Negative Stock Prevention

I don't see where you define the quantity variable, should that be instance.quantity? Also, presumably you want to check if quantity is greater than or equal to qu rather than 0.
Try changing `if quantity > 0` to `if instance.quantity >= qu`

Maybe change quantity and reorder_level to PositiveIntegerField?

Re: What Programming Language should i learn

LOL, You mean you learned Django without first learning Python?.

It depends but My suggestion would be to learn Python and later learn C++ (So then you will get much clarity on what is the difference between these two languages). Then after that, you can learn Data structure and Algorithms.

Maybe change quantity and reorder_level to PositiveIntegerField?

Re: Negative Stock Prevention

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.

See: 
* https://docs.djangoproject.com/en/4.1/ref/models/instances/#saving-objects
* https://docs.djangoproject.com/en/4.1/ref/models/instances/#what-happens-when-you-save
* https://docs.djangoproject.com/en/4.1/topics/db/models/#overriding-model-methods

Re: hello guys I need help

Hello Bode.
When you say different types of pages what do you mean?

Do you mean you want users to see pages specific to them?

For instance, if my name is Joshua, you want me to see a page with my name and if your name is Bode, you want me to see a page with your name. Is this what you mean?

Negative Stock Prevention

Hello,

Please help crack the below code, I want to prevent negative stock, and if the stock is == 0, deduct it from reorder_level instead.
