am not sure, maybe this is why you are confused. with django version 2+ you have url dispatcher function called path() and with that function you dont need to use regex. while with older version django you use url() and its using regex.
you hit the point!!! now django is doing different

That's why it's better to use same db on dev / prod

Yes, I realized it later

Ping me If you have any doubts in that
Mirco
It's not a Django "issue" imho , I think the main reason why is lots of developers don't spend enough time to design before writing code
Sebuhi
Yes I am using it right now
Cool it is good to see someone also implementing MQTT with django. Well my concerns is about we will have many devices to connected broker, and publish their data to broker I will need subscribe them and pass it to webscoket using channels in case of actions (by user) i should publish to the device as well

How is your case? What you have to do with mqtt?
I am using it to for a gateway , Device to gateway then to cloud
Sebuhi

I’m trying to create a form from two models, one has FK for the other one.
Any direction to which approach should I use

Hello folks, is it ok to have a django app that requires the older version of django (1.10.5) whereas the whole project uses version 2.0.9. Can I have two different versions of django in the same virtualenv?
Muflone
I doubt you could
Victor
There's no way pip would allow it?
Muflone
the only workaround I could think is to make django package private
Muflone
not installed by pip (or moved) but installed into your application
Muflone
and using relative imports... but I still doubt it will works fine everywhere
Victor
And is it possible to have two different venv with different versions of django and then somehow to reffer to them from one project? Is that practice legit?
Muflone
I don't think this is possible
Muflone
you could have two applications run in parallel which communicate via some API
Victor
I am just working on a project and we were sent private django apps one of them requires older django version unlike the entire project and I am trying to figure out whether we were sent a wrong version of the app or I am not suficiantly competent to get it working. I am truly relatively new to django with no comercial dev experience
Muflone
I understand your words but I don't think you can run two versions of the same module at the same time
Muflone
Apart splitting the thing in two projects
Victor
Alright got it
Victor
Thank you buddy
Muflone
Have you tried to test the application with newer Django?
Muflone
Maybe the changes are trivial
Victor
The thing is that this private app have django==1.10.5 specified in setup.py and it reinstalls the current version of django my project uses
Muflone
Try to change it 😄
Victor
And to actually run the project i have to install newer version back, but it is gonna be incompatible with the private app
Victor
I can technically change it but this is private component that we were sent
Victor
Anyway tanks for the answer

you can try use model form, so you can access related model from its related name

Usually I fix the no such column error by running
manage.py migrate --run-syncdb

but still dont know why i got that error
because in your migration file you already have that fields but not in your db and you made changes in db manually
inchidi
make sure to stay consistent in using django migrations, dont change your db manually and use migrate instead
iNcAeLuM
because in your migration file you already have that fields but not in your db and you made changes in db manually
now it works fine i didnt change anything in the database i just added a line in models.py and then i did makemigrations and i go t that error
iNcAeLuM
so i opned my database and added that fiield and the run makemigrations
iNcAeLuM
and run well
inchidi
if its okay for you to delete your current database, i recommend you reset migrations to revert things you break
iNcAeLuM
but the point is: yes, i solved the error, but i still dont know why i got that errror
inchidi
but you should remember to never manually change the database again
