Redis and channels with Windows
I'm trying to get a var to my consumers.py to send data to the client in real time as a function does API calls and returns that to the browser. I know channels needs Redis to function, but why? Why can we not just pass a list as it's built to the consumers class or any variable for that matter? From another answer: to store the necessary information required for different instances of consumers to communicate with one another. But what if I only will use one websocket connection, and only one user is allowed to be logged in at a time? This will be locally hosted only and the function is outside of consumers.py that returns the data so subscribing to groups may be where I need these. Am I missing something or is redis / memurai a must here? I just can't help but to feel there's an easier way. -
Django Custom Manager Method that returns object when asked by value
I'm trying to make a method for a model "Clase" that returns a "Clase" whose "codigo" value matches an argument. So far i have this: class CodigoClaseManager(models.Manager): """ Custom manager that enables geting a Clase by codigo """ def get_by_code(self, code): return super(CodigoClaseManager,self).get_query_set().filter(codigo=code) class Clase(models.Model): nombre = models.CharField(max_length=100) codigo = models.CharField(max_length=100) byCode = CodigoClaseManager def __str__(self): return self.nombre class Meta: managed = True db_table = 'clases' My problem is that, when i try to call this get_by_value method, it always tells me that the argument "self" is missing. >>> Clase.byCode.get_by_code(code="1234") Traceback (most recent call last): File "<console>", line 1, in <module> TypeError: get_by_code() missing 1 required positional argument: 'self' Am I taking a wrong aproach or is it an error in my code? I have recently started learning django and would very much apreciate help, thanks. -

How can I join three Django Models to return a queryset?
I want to create a queryset that references three related models, and allows me to filter. The SQL might look like this: SELECT th.id, th.customer, ft.filename, fva.path FROM TransactionHistory th LEFT JOIN FileTrack ft ON th.InboundFileTrackID = ft.id LEFT JOIN FileViewArchive fva ON fva.FileTrackId = ft.id WHERE th.customer = 'ACME, Inc.' -- AND ft.filename like '%storage%' --currently don't need to do this, but seeing placeholder logic would be nice I have three models in Django, shown below. It's a bit tricky, because the TransactionHistory model has two foreign keys to the same model (FileTrack). And FileViewArchive has a foreign key to FileTrack. class FileTrack(models.Model): id = models.BigIntegerField(db_column="id", primary_key=True) filename = models.CharField(db_column="filename", max_length=128) class Meta: managed = False db_table = "FileTrack" class TransactionHistory(models.Model): id = models.BigIntegerField(db_column="id", primary_key=True) customer = models.CharField(db_column="Customer", max_length=128) inbound_file_track = models.ForeignKey( FileTrack, db_column="InboundFileTrackId", related_name="inbound_file_track_id", on_delete=models.DO_NOTHING, null=True, ) outbound_file_track = models.ForeignKey( FileTrack, db_column="OutboundFileTrackId", related_name="outbound_file_track_id", on_delete=models.DO_NOTHING, null=True, ) class Meta: managed = False db_table = "TransactionHistory" class FileViewArchive(models.Model): id = models.BigIntegerField(db_column="id", primary_key=True) file_track = models.ForeignKey( FileTrack, db_column="FileTrackId", related_name="file_track_id", on_delete=models.DO_NOTHING, null=True, ) path = models.CharField(db_column="Path", max_length=256) class Meta: managed = False db_table = "FileViewArchive" One thing I tried: qs1 = TransactionHistory.objects.select_related('inbound_file_track').filter(customer='ACME, Inc.') qs2 = FileViewArchive.objects.select_related('file_track').all() qs = qs1 & qs2 # … -

Django media uploads to Amazon S3 and restricting access to certain users
I am creating a flutter application with Djano backend where users can create/join groups and upload files (pictures, videos etc) to the group. I set up AWS S3 storage to handle media file uploads. However, now I'm at a point where I want only members of a group in the app to be able to see those files/pictures and restrict access to those files/pictures where you are not a member of the group. right now My bucket settings is set to public and anyone that has a link to the URL can access/view that file in the browser. How would I implement if someone grabs a hold of that URL , they shouldn't be able to access the file by going to the link. essentially, some content like profile pictures can be public and anyone can access that but no one can just go to their browser and type in a URL for a certain file link and access it. How would I go about doing this? Are there any good tutorials that you can link me or documentation that discusses this? -

How to get only the last month's records present in the database, using queryset django?

So, i have a rather usual "update item" page that is a class-based view which inherits UpdateView. (in views.py it looks like "class ItemUpdateView(UpdateView) and it has method get_success_url(self) defined which contains the redirect url where user will be taken after clicking "Update" button. My problem is that in my application, there are two different pages that could lead me to this "Update item" page, and depending on the page that user comes from - i want to take the user back to either pageA or pageB upon the successful update of the item. I wasn't able to find the best-practices of how to handle this anywhere on the web, so - would really appreciate the help. My guess is that I need to create an additional parameter that will be a part of the url and will contain A or B depending on the pageA or pageB that user came from, i.e. the url itself would be something like '/itemUpdate/int:pk/sourcepage' => '/itemUpdate/45/A'. Does that sound like a correct aproach or is there a better way? -
Django migrate won't work due to Postgres InsufficientPrivilege error provisioned by terraform and helm
We're are hitting a issue with our Django app and are unable to find the underlying problem. Our Django app runs on Kubernetes and is managed by Helm. When we upgrade the app, a Helm upgrade job is triggered that makes sure that a manage.py migrate is run. The migrate job runs with database admin privileges, not the customers postgres role. The error we're getting is: InsufficientPrivilege: permission denied for table RouteInstance This error must have something to do with creating a reference from a new table to a existing table, but we can't find it. Maybe it's in the Terraform resources config, or are the grants not sufficient. We don't use any extra grants since the admin account should be a real admin (Digitalocean doadmin). Any help would be awesome, we're stuck at the moment. Some context on our app deployment: The Helm template is being deployed by Terraform, the application deployment consists of: Create a subdomain record Create a namespace Create S3 buckets and a account Deploy the Helm chart (helm_release), here we use a values list with a templatefile. Between these values there are variables: postgres_user_username (used to run the app) postgres_user_password postgres_admin_username (used to perform the … -
How to prechoose an option in django form
I made a project in Django, on one page I have a list of buses with a button for each. I would like these buttons to lead to another page with ride cost calcutor, but there is one catch. One of the option in this form is a bus type, so I would like the button to lead to the form but with already chosen proper option. So if i push the button next to Volvo bus it will take me to the form and Volvo option will be chosen, if I push the button next to Setra it will be chosen in the form and so on. I tried giving every option unique id, and then in a tag href="{% url 'base_app:calc' %}#Volvo" but it only shows me the form, without choosing option. How should I go about it? -
DRF: Full Example of ListSerializer like Django's Admin-Inline?
I'm trying to wrap my mind around DRF's ListSerializer in combination with a foreignkey-model. The aim is to have something similar to Django's admin-inline Formula. Unfortunately, I can not find a full example on the documentation or SO examples: two models, two serializers and a viewset. Suppose we have a model bit like in the SO example DRF ListSerializer and ListField : class Musician(models.Model): name = models.CharField(max_length=50) comment = models.TextField(blank=True) class Album(models.Model): artist = models.ForeignKey(Musician, on_delete=models.CASCADE) name = models.CharField(max_length=100) So I try to put them in serializers like that: class AlbumSerializer(serializers.ModelSerializer): class Meta: fields = 'artist', 'title' model = Album class MusicianSerializer(serializers.ModelSerializer): class Meta: fields = 'name', 'comment', 'albums' model = Musician albums = serializers.ListSerializer(child=AlbumSerializer(), source='album_set') And then I want to build a ModelViewSet on it, so that I can work with it, just like in Django-Admin-Inline. But this is not working just like that: class MusicianViewSet(viewsets.ModelViewSet): queryset = Musician.objects.all() serializer_class = MusicianSerializer But it's difficult to test, the HTML front-end does work, and in the tests I got (in a slightly different situation) an error message something like: {'album_set': [ErrorDetail(string='This field is required.', code='required')]} which I could not understand, not even after digging hours in the source code. So … -

Modifying the root folder only for one view or specific template (django, jquery, html)
I am trying to figure it out for several days, I am running out of time. I would need to make this works without changing the "<a href='/about'>About Text</a>" part (please, see code below). Basically, once the content is parsed, the link will reference to https://www.myhost.com/about, I would need to change that to https://www.myhost.com/something_more/about. I can not change the site root, I would to do it inside this specific view, the HTML template, or the jquery used (if there is a way to do it). I tried different things but without success. This is the code of the template: <div id="contents"></div> <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script> $(document).ready(function () { var iframe = document.createElement("iframe"); $('#contents').append(iframe); iframe.contentWindow.document.open(); iframe.contentWindow.document.write("<a href='/about'>About Text</a>"); iframe.contentWindow.document.close(); }); </script> This is the view: def this_view(request): return render(request, 'my_app/this_view.html') Thank you, I appreciate any help.
