iNcAeLuM
is this correct?
iNcAeLuM
but for what is created var for?
Mirco
Docs explains it so well
Anyway if Django finds matches, it will use defaults to update instance otherwise Django creates new one with first_name and last_name specified ( not defaults )

Hello everybody!
Is it possible, to register by to register forms in Django?
hi i have a code for register and login
iNcAeLuM
iNcAeLuM
obj, created=.....
iNcAeLuM
created is nmot used
Mirco
Obj is for instance, created for True/False it depends on the result of the query
Mirco
created is True if obj does not exist
Mirco
False if exists and Django updates the instance

dont getting it ... so in default i dont put the field i want to check if it is matched?
Mirco

Default is for telling Django what it has to update if match is found
Mirco
It's simple

hello guys, i am trying to understad update_or create() in django docs, but am little confused, in this example:
´´´
obj, created = Person.objects.update_or_create(
first_name='John', last_name='Lennon',
defaults={'first_name': 'Bob'},
)
```
i guess that if first_name and last_name is matched then updated all fields with defaults dict,
and if it dont matches then create new one obj with all fileds including fist_name and last _name
Let's say Django finds John Lennon
created will be False and Django will use defaults to update John to Bob , so you will have Bob Lennon
Mirco
Otherwise, created will be True and you will have a new instance with John Lennon as first and last name
Mirco
Enough clear ? 😊
Mirco
Let's say Django finds John Lennon
created will be False and Django will use defaults to update John to Bob , so you will have Bob Lennon
Take a breath and read again 😊

let me take a sec to undestand what are u sayin
No offence , have you programmed in python before or you headed directly to the framework?

Let's say you have a red apple, but it's not on the tree yet
When you ask Django to update or create an apple with red as color parameter , Django will tell you : hey I didn't find any apple on the tree , so I will create one for you with color equals to red
Mirco
Now you have a red apple on the tree 😁
Ask again Django to create or update, if it's on the tree change its color to yellow ( specified into defaults )
Django will tell you: hey, I've found one so I will change its color to yellow , I already know what color by taking it from defaults
Now you have an "updated" apple 😊
Mirco
Is it now clear ? 😁
iNcAeLuM
lets say i have this dict:
{"match":"barcelona - Madrid",
"time_match": "any_time",
"goal keeper":"anyone",
.
.
.
}
so i want if match is the same then update all fields, if not then create a new one
Mirco
So your dict will go inside defaults dict
Mirco
including "match" i guess
Including all you wanna update if django will match your query
iNcAeLuM
obj, created = match_comming.objects.update_or_create(
match="barcelona - Madrid",
defaults={mydict},
)
iNcAeLuM
if matches then update all other fields
iNcAeLuM
if not then create new one with all dict filds
iNcAeLuM
?
Mirco
if not then create new one with all dict filds
Nope, it will create a new instance with just match equal to Barcelona - Madrid
Mirco
Defaults is for updating
iNcAeLuM
it seems very confuising for me
Mirco
I don't know how to explain you better
Read again the tree and apple example
Anders (izzno / gooood) 🇳🇴
separate the variables. clean your code.

it seems very confuising for me
def update_or_create(defaults, **kwargs):
if self.model.objects.filter(**kwargs).exists():
obj= self.model.objects.get(**kwargs)
obj.update(**defaults)
return obj, False
else:
obj= self.model.objects.create(**kwargs)
return obj, True
inchidi
not literally equals with this because actually django use atomic transaction. but basically this function produce similar behaviour
Mirco
def update_or_create(defaults, **kwargs):
if self.model.objects.filter(**kwargs).exists():
obj= self.model.objects.get(**kwargs)
obj.update(**defaults)
return obj, False
else:
obj= self.model.objects.create(**kwargs)
return obj, True
tree and apples example was better than code 🤣🤣
inchidi
sometimes familiar codes easier to read than human languages tho 😂
Mirco
🤣 also docs mentions the piece of code Django runs under the hood

Hi guys, can someone tell me how I can register my models on LogEntry without using admin.py?
Dev
I have 1 django project and 1 python project independent of django...
I want both to use same database and models.
In standalone python I am using peewee ORM.
What's the best way to keep both in sync so I don't have to code things twice.
Right now if I change a model in django, I have to make same changes in peewee models also and sometimes also change relevant codes in both projects.
What's a better solution for this?
Django can also be used in standalone projects, read about that, and you'll still have the power of the ORM

Have any of you used Mongo in pararell with sql to store files? If so, which ORM/modules did you use ?

Is it necessary to use a web server for serving media files in production mode or we can continue using a media folder??
Mirco

You can use ngine x as a proxy for you media folder. Python will handle the upload and nginx will handle serving them.
Anders (izzno / gooood) 🇳🇴
It's not very complicated.
Mirco
You can use ngine x as a proxy for you media folder. Python will handle the upload and nginx will handle serving them.
or you can upload them into AWS S3 for example
Anders (izzno / gooood) 🇳🇴
Oh, yes better :)
Anders (izzno / gooood) 🇳🇴
but then it's abit more work and "complexety"
Anders (izzno / gooood) 🇳🇴
Or you could store them in Mongo. But it does not seem like someone here has done it yet, so ill post it when I'm done 😂

I'm using digitalocean.
Mirco

not so much, just 3/4 variables into settings to setup boto3 connection
Mirco
with django-storages is simple
Anders (izzno / gooood) 🇳🇴
of course, django has abstaction for everything :)

There is no more 🤭
Anders (izzno / gooood) 🇳🇴

Anders (izzno / gooood) 🇳🇴
Your save is not inside your loop...
Yep
It is..i just edited it wrong
Yep
Its the main code for the 2 parts..return works
Yep
I get the data displayed right(Tested it with pycharm)
Anders (izzno / gooood) 🇳🇴
So your code is indented under your for loop ?
