Hi folks is any troubles for upgrading django (with drf) project from 3 to 4? And may be there’s some version control for Python libs, that can find new one version , that not conflict with each other’s?
It is not a lot of trouble, however I try to only use the LTS versions of Django.
pip will handle a lot of conflicting version for you.
And you should always read and follow Djangos upgrade guide; https://docs.djangoproject.com/en/4.0/howto/upgrade-version/

How to use font awsome in admin django panel
Since Django uses its own template mechanism for the admin panels too,
You can easily override the templates used by Django. See this article: https://realpython.com/customize-django-admin-python/
Or get some inspiration from this project: https://github.com/fabiocaccamo/django-admin-interface

Hello
I have lists of countries, states, cities.
Each country has states and each states has cities.
I added the states and it working fine. For example if I select United state, it shows me the list of the states.
My problem with cities, When I select the state, it pulls all the cities which around 4000+ cities.
I want to get the list of the state cities only not all the US cities
Here is my code

I am missing the code where you actually select the state.
The code in pastebin shows us the JSONs and how you import them.
How do you select your cities?
It should be something like; City.objects.filter(state=state)

They are not exist. This script for the new deployment. This is where I'm struggling.
I need to pull cities that belong to California using the state_id so it will pull small amount of cities instead of the whole list
Raad
So the states are exist since the code working till the city part.
Sorry if I'm confusing you but the code will add countries first and then add the states. Last part is to add the cities

Lines 121/122/123 make sure the cities are created for the states they belong in.
Apart from some optimizations I do not yet see what is going wrong.
Is there an error or do you just have a lot of cities in the database? And those cities are not related to any state?
I assume you are constantly working on a clean database?
Raad
So what is the right way to add the cities? is there any other way to load them directly from the json file instead of adding them in the database? I'm building a saas product and they should be available to all clients.

This can be a correct way to do it. You can also suggest one big JSON with the three levels at once.

I get this error
ValueError: Cannot assign "'7'": "City.state" must be a "State" instance.
Every city related to a specific state. For example, Alabama cities will have the state_id of Alabama.
I deploy a separate server with its own db for each client.

My ValidationError in django forms are not showing error here is the forms.py link https://dpaste.org/KuvLg#L5,10
Raad
Okay replace;
state=st.state_id
With:
state_id=st.state_id
This is mean I have to add new filed state_id in the city model?
Raad
This can be a correct way to do it. You can also suggest one big JSON with the three levels at once.
I see. Then I can use the forms to load them from the internet or locally?
Koen de

Django expects an instance of State at that part of your code.
The trick is to use <field>_id to set an in instead of an instance and let Django find the instance itself
Koen de
I see. Then I can use the forms to load them from the internet or locally?
You can automate it, there are some open APIs around like https://public.opendatasoft.com/explore/dataset/us-cities-demographics/api/

state=st.state_id
With:
state_id=st.state_id

when I change the state_id to anything else, I get this error

So the ids of the states in the json and the pks in the database do not equal. Okay.
Then you should get a handle to the State before assigning it to the city
Raad

Yes they are not equal.
is it possible to use the ids in the json as a pk?

And what is the real value of “valname” before checking its len()?
Both can be investigated with “pdb”

yeah it was not executed

But the same issue. it loads all the cities regardless of the selected state

I do not understand your question.
Yes all cities are imported because there is no filter. You just import them
Koen de
When you view the cities in the database or Django admin, are they related to a State?
Raad
I do not understand your question.

Thank you very much. I appreciate your help.
I have a searchable dropdown and when I click on it, it makes the page slow. It also make a very long scrollbar
Raad

they are not related right now. If I select Cali, it shows all the US citites
Koen de
Both have nothing to do with the import. Check if there is any filtering in the dropdowns. At least State should be provided to filter the cities.
Raad

They have ids that different then the one in JSON file. I can see the cities in Cali for example has the id "80" .
