Allow End User To Add To Model, Form, and Template Django
Is there anything that someone could point me towards (a package, an example, a strategy, etc) of how I could implement the ability for an end user of my app to create a new field in a model, then add that model field to a model form and template? I’m thinking of the way that Salesforce allows users to add Custom fields. I don’t really have any start point here I am only looking to learn if/how this might be possible in Django. Thanks! -
Using Django for incoming Streaming API?
We would like to implement a connection to a streaming API and store the continuously incoming information in a relational database. There will be roughly 50,000 database inserts per day. We prefer to implement this in Django. In short, we will create a service that establishes a GET connection to a server and this connection never closes. However, is Django suited for these purposes? In other words, where should this service best be implemented in Django, because it does not contain a view. Likewise, how does Django deal with these concurrent activities? Wouldn't this service block the Django app from doing anything else? Thanks! -
Django model not working in admin section on Heroku
I want to deploy a new model on my heroku app, for making comments in my blog app. For this, I created a new class 'Comment' in models.py and added it it also to admin.py. Then i migrated it locally: manage.py makemigrations manage.py migrate Next i uploaded it to heroku: git add -A git commit "add model" git push heroku master and migrated it there: heroku run python manage.py migrate But then it gives me following message: psycopg2.errors.UndefinedTable: table 'blog_comment' does not exist I tried to use the hint heroku run python manage.py migrate --fake It seems that with this it will create the model and show it in the admin section. But when I click on 'Comment' there, it will just give out "Error 500". So it is not possible for me to access the Comment model. On my local computer it all works without a problem, but on heroku I think i forgot something. Can anyone help? Best regards -

Can anyone explain this django model?
I trying to learn django. I am trying to understand slug and collected few lines of code which generates url with pk & title text. It works fine but cann't understand everything.

Why is Django not saving to database?
I believe I have the correct code, but when I submit the form, nothing is saved to the database.

Django urls.py: passing dynamic url parameter into include()
I found in Django docs (https://docs.djangoproject.com/en/3.0/topics/http/urls/#passing-extra-options-to-include) that I can pass any constant into include() statement. Here in docs' example we are passing blog_id=3. from django.urls import include, path urlpatterns = [ path('blog/', include('inner'), {'blog_id': 3}), ] But what if I want to pass dynamic url parameter into include()? I mean something like this: from django.urls import include, path urlpatterns = [ path('blog/<int:blog_id>/', include('inner'), {'blog_id': ???}), ] Is it possible? -
Any Better Way to get the Print Result For Django Model

Mirror/inherit a module for outputting some fields of the original
Is it possible, in Django, to create a module which is linked via a OneToOneField to another one, which only outputs a single field of its parent? Something like: class Venue(models.Model): # this is the parent venue_name = models.CharField(max_length=50) venue_city = models.CharField(max_length=50) venue_country = models.CharField(max_length=50) class VenueCity(models.Model): # should this be (Venue)? venue_city = # this is the OneToOneField linked to the venue_city field of the parent I need this because it'd be very handy for using it with a select2 field ( django_select2 - limit the returned text to a specific field in module) and I cannot use a @property, only a proper module. -

Django Rest FrameWork: Combining data from different models before sending response
I have a default user model I created a userprofile model as shown below. from django.contrib.auth.models import User from django.db import models from django.db.models.signals import post_save from users.utils.age_validator import MinAgeValidator from django.core.validators import MaxValueValidator, MinValueValidator class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) mobile_number = models.IntegerField(blank=True, unique=True, null=True) profile_image = models.ImageField(upload_to="proile_image", blank=True) def __str__(self): return self.user.username def create_profile(sender, **kwargs): if kwargs['created']: user_profile = UserProfile.objects.create(user=kwargs['instance']) post_save.connect(create_profile, sender=User) There is a search view written as shown below class FindUser(ListAPIView): permission_classes = [IsAuthenticated] search_fields = ['username', 'first_name', 'last_name'] queryset = User.objects.all() serializer_class = FindUserSerializer filter_backends = (filters.SearchFilter,) pagination_class = SearchLimitPagination Then I defined serializers to combine data from both models. class UserProfileImageSerializer(serializers.ModelSerializer): class Meta: model = UserProfile fields = ('profile_image',) read_only_fields = ['profile_image'] class FindUserSerializer(serializers.ModelSerializer): image = UserProfileImageSerializer(read_only=True) class Meta: model = User fields = ('id', 'username', 'first_name', 'last_name','image') The question is similar to the this(Django REST Framework and combining models).

Using Django + MongoDB with unstructured data
I've boradly seen Django used together with MongoDB (with modules like djongo) with structured data using Models. This conflicts one of my requirements: being able to store data in an unstructured way (missing fields, nested objects ...) since the usage of Django Models enforces the specification of all document fields. I thought of encapsulating all the required DB calls in a DAO object but it sounds a bit alien in the Django scene. -
save inputs from 2 forms, through one view into 2 tables django

Selectable table with django
My mission here is to add a checkbox in first <td>, so I can select the rows I want and only export those to csv. I got the export function working and everything, but I can't figure out how to sort so it's only those I check, who will be exported. They as well needs to change a boolean from False to True when they've been exported. Let's therefore say, to keep it simple, that I'd like to do X with the chosen rows and change a boolean, on a button click. I got a table looking like this: <table id="example" class="display" style="width:100%"> {% for shipment in object_list %} <tr role="row" class="odd"> <td class="sorting_1">{{ shipment.increment_id }}</td> <td>{{ shipment.full_name }}</td> <td>{{ shipment.street }}</td> <td>{{ shipment.zip_code }}</td> <td>{{ shipment.city }}</td> <td>{{ shipment.telephone }}</td> <td>{{ shipment.email }}</td> <td>{{ shipment.products }}</td> <td>{{ shipment.lost_because_of }}</td> <td>{{ shipment.custom_comment }}</td> <td>{{ shipment.date }}</td> </tr> {% endfor %} </table> My views.py is as following: class ShipmentList(LoginRequiredMixin, ListView): html_title = 'All Shipments' page_title = 'All Shipments' login_url = '/log-in/' redirect_field_name = 'accounts:log_in' model = models.NewShipment paginate_by = 100 # if pagination is desired template_name = 'shipment-list.html' How can I make this happen based on a ListView?

AWS S3 Rejects API Call with HTTP 400
I am following this tutorial on getting Django to upload files to AWS S3 asynchronously. The problem is that I am getting this message back from the call that actually uploads the file (the other two come back HTTP 200). <Message>The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.</Message> The first hunch was to set AWS_S3_SIGNATURE_VERSION = "s3v4" in the settings.py, but that was both futile and superfluous since the version of Boto supports only this signature and so does the region of the AWS.

how to get distance in drf api reponse?
I have exactly the same problem as this SO question (Sorry for the link and not writing the whole content again.) Also, I have already implemented the solution given for the same problem. but I am not getting distance in API response. I haven't added distance in serializer fields so definitely, it won't show up in response. But when I add it to fields I get following error. Field name distance is not valid for model Address. I also tried to write a serializer method field but was not sure how to pass the location received in query params to the serializer for comparison. So the question is how the distance is supposed to send in API response?
