How to create get or create object from serializer data
I'm passing two serializer with one view. On creating object I want to first create CaseId object which is why I'm poping out CaseObject from validated data. I want to get or create an object with the given data. Because I want to pass that to the CaseMessage object as a reference. class CaseMessageSerializer(serializers.ModelSerializer): case_id = serializers.IntegerField(required=False) case_object = CaseIdSerializer(required=False) message_type = ChoicesFieldSerializer(choices=CaseMessage.MESSAGE_TYPE) body_format = ChoicesFieldSerializer(choices=CaseMessage.BODY_FORMAT) class Meta: model = CaseMessage fields = "__all__" depth = 1 def create(self, validated_data): raw_case_object = validated_data.pop('case_object', None) # Not Getting or creating object with the given data. case = CaseId.objects.get_or_create(**raw_case_object) case_message = CaseMessage(**validated_data) case_message.caseid = case case_message.save() if not CaseAudience.objects.filter(case_id=case).exists(): case_audiance = CaseAudience( case_id = case, source_message = case_message, ) case_audiance.save() return validated_data The Errors are as follows: -

How to return data from two different models in django?

Django: Generating multiple similar tables and link them with another table
I want to store the historical stock price data in a database. E.g. I want a table which will contain the historical data of AAPL stock. In this table I'll have columns like date, open_price, close_price, etc. and this table will be linked to another table which will hold the fundamental information of the stock. Now, I want to do this for multiple stocks. As there are thousands of stocks, it'll be a very time consuming process to create a model for each stock. So, I want something like the following: class StockData(models.Model): date = models.DateField() open_price = models.DecimalField() close_price = models.DecimalField() high_price = models.DecimalField() low_price = models.DecimalField() adj_close_price = models.DecimalField() volume = models.PositiveIntegerField() class StockInfo(models.Model): stock_name = models.CharField(max_length=30) # other fundamental information # How to do this: link the instance of StockData here, which will hold the data of particular stock with name 'stock_name' How should I go about doing this in django? -
In Django, how does passing in a reference to the views function eventually get called by the path function?
I know my question is very similar to what is "request" in Django view but I can't make sense of the answers provided. I have also read the documentation that is related to my question, but still don't understand. I would greatly appreciate any elaboration to the other answers in addition to anything I ask that isn't covered in that question. In views.py, we can have something like this: from django.shortcuts import render from django.http import HttpResponse def home(request): return HttpResponse("Hello, World") And in urls.py we have something like this: from django.urls import path from . import views urlpatterns = [ path('', views.home, name='hello-world-home'), ] My question involves views.home being passed in as a parameter to path. Based on one of the answers to a similar question, views.home is passing the "function object" as a parameter to path. If it's not calling the function, don't we need pass it like this: views.home()? How does it eventually get called by path? If there is some documentation about being able to pass in a reference to a function in Python, I would appreciate it if you could link it. Is being able to pass in a reference to a function exclusive to … -

Setting up OSRM on Heroku
Making a new thread for this post Setting up OSRM (Open Source Routing Machine) on Heroku because it's been 6 years and the older buildpacks don't seem to work, at least for me. Has anyone had recent success setting up OSRM in their Heroku apps? I've tried several different ways over the last couple days but nothing has worked. My situation may be specific because I already have a django heroku app and want to run OSRM inside so I can access it from the local host. I've tried using the following buildpacks separately, and they each fail when I try to push my code. I think they're just not maintained and outdated by now. https://github.com/chrisanderton/heroku-osrm-buildpack https://github.com/jpizarrom/osrm-heroku I currently already use the two below buildpacks and have added the osrm ones on top: https://github.com/heroku/heroku-geo-buildpack.git heroku/python [one of the osrm buildpacks] I was thinking that maybe there's no recent literature on setting up OSRM on Heroku because Heroku Docker is much easier to use now. But I've also tried setting up OSRM with Heroku Docker and failed. I would like to run the docker image inside my current app, but my app doesn't use Heroku's container stack. And I've also been … -

how can we add data into database using migration files in django?

Is there a proper design pattern for this situation?
I'm building a simple crud app in Django which is basically enhanced reporting for commerce related software. So I pull information on behalf of a user from another software's API, do a bunch of aggregation/calculations on the data, and then display a report to the user. I'm having a hard time figuring out how to make this all happen quickly. While I'm certain there are optimizations that can be made in my Python code, I'd like to find some way to be able to make multiple calculations on reasonably large sets of objects without making the user wait like 10 seconds. The problem is that the data can change in a given moment. If the user makes changes to their data in the other software, there is no way for me to know that without hitting the API again for that info. So I don't see a way that I can cache information or pre-fetch it without making a ridiculous number of requests to the API. In a perfect world the API would have webhooks I could use to watch for data changes but that's not an option. Is my best bet to just optimize the factors I control to … -
when creating a record an error is declared: NOT NULL constraint failed: faq.user_id but the user was declared in views

Django model with a type field and lots of custom logic
I have a Django model that has a type field: class MyModel(models.Model): type = models.CharField(choices=MyModelTypes.choices) ... def some_func(self): if self.type == "TYPE_1": do_something_1() elif self.type == "TYPE_2": do_something_2() This is getting really complicated and is causing conditionals to be littered everywhere, so I'm wondering if there's some way to cast my model into some specific object that has a specific implementation of that some_func() function for the type.: class MyModelTypeA: ... class MyModelTypeB: ... class MyModel(models.Model): type = models.CharField(choices=MyModelTypes.choices) ... def some_func(self): # Obviously this won't work, but I want something that allows me to turn # MyModel into the right type then call the `some_func()` (which has logic # specific to the `type`). MyModelType(self).some_func() Or maybe that's the wrong approach. Any ideas? -
When Django Form is Invalid, why only file type input is rest?
If there is an invalid field after submitting my Django Form, the other fields have input values when submitted, but only the inputs of the file type will be emptied. I don't think there's anything to change in Dajngo. Perhaps this is a characteristic of html file type input? For example, my form compresses video files uploaded by users. And it takes quite a bit of time. If something goes wrong after submitting the form, the user must select the file again and proceed with the compression process. This is not good. Forms.py class VideoArtUploadForm(forms.ModelForm): class Meta: model = models.VideoArt fields = ( "video", "thumbnail", "poster", "title", "year", "artist", "description", ) widgets = { "video": forms.FileInput(attrs={"accept": "video/mp4"}), "title": forms.TextInput(attrs={"placeholder": "Il titolo del video"}), "year": forms.TextInput( attrs={"placeholder": "l'anno in cui il video è uscito"} ), "artist": forms.TextInput(attrs={"placeholder": "Il nome di artista"}), "description": forms.Textarea( attrs={"placeholder": "una descrizione del video "} ), } def clean_thumbnail(self): thumbnail = self.cleaned_data.get('thumbnail') if thumbnail: if thumbnail.size > 10*1024*1024: raise forms.ValidationError("Thumnail si deve essere meno di 10MB") return thumbnail else: raise forms.ValidationError("Thumnail è necessario") def clean_poster(self): poster = self.cleaned_data.get('poster') if poster and (type(poster) != str): if poster.size > 10*1024*1024: raise forms.ValidationError("Cover image si deve essere meno di 10MB") … -
How best to validate number of total reverse relationships before saving
I have an Item model that is reverse-related to two other models (ItemComponent and or ItemComponentCategory). The idea is I'd like to be able to validate that Items have no more than 4 relations to the two other models, combined, before being saved. class Item(models.Model): name = models.CharField(max_length=40, unique=True) class ItemComponent(models.Model): parent_item = models.ForeignKey(Item, related_name='components') class ItemComponentCategory(models.Model): parent_item = models.ForeignKey(Item, related_name='categories') I'd like to create a validation that raises an error before saving either the Item, ItemComponent, or ItemComponentCategory objects if the saved objects will result in > 4 object relations between them. I have tried adding something like this to the clean methods for all three: def clean(self): if (self.parent_item.components.count() + self.parent_item.categories.count()) > 4: raise ValidationError(_(f'Items can have no more than 4 components and/or component categories')) This seems to work as long as the Items and their relations are already saved and you're trying to add more relations. However, if I create a TabularInline in the ItemAdmin to add these 'sub types,' if you will.. I can create a new Item and add as many of these sub types and save it no problem. What am I missing here? -

Updating admin/staticfiles with Django
I am having trouble with updating the css, img, fonts, and js admin files when I upgrade Django. I first noticed this when I upgraded to Django 2.0 (see here), and now the problem is worsening as I upgrade to 4.0. The backend functionality is working perfectly well. But now when I access the admin console, the homepage remains on the top of the browser page, even when I navigate to different models. I noticed that none of the /static/admin/ files (css, js, img, fonts) were updated on my local machine when upgrading from Django 2.2.24 to 4.0. Should I have expected these files to update along with Django? Am I missing a step to ensure that the admin static files are updated to reflect the newest version of Django? -

Python - "cannot unpack non-iterable int object" when importing json data into database
I'm working on an importer to import a list of facilities from a json file into my database. The importing works.
