DRF Serializer Error: AttributeError: 'FeedPostSerializer' object has no attribute 'auth_user'
I´m creating a newsfeed in an APP. A user is logged in and sees the posting of other users. Therefore I need two user models (user + auth_users) Now I want to add a boolean field that shows if a post is already liked or not. I already looked at the documentation and other posts here but I can´t find a solution. The auth_user is shown in the response but I can´t included it in the "get_already_liked" function class NewsPostSerializer(serializers.HyperlinkedModelSerializer): user = UserSerializer(read_only=True) auth_user = serializers.PrimaryKeyRelatedField( read_only=True, default=serializers.CurrentUserDefault() ) attachments = AttachmentSerializer(read_only=True, many=True) already_liked = serializers.SerializerMethodField() def get_already_liked(self, request): liking_kwargs = { 'post_id': request.id, 'user_id': self.auth_user } if LikePost.objects.filter(**liking_kwargs).exists(): return True else: return False class Meta: model = Post read_only_fields = ( 'id', "user", 'creation_time_stamp', 'auth_user', 'ready_liked', ) fields = ( 'id', 'user', 'creation_time_stamp', 'last_update_time_stamp', 'description', 'attachments', 'already_liked', 'auth_user', ) -
Render JSON in HTML Table with Django/JavaScript
Friends, I need your help! I am new to Python / Django and I am doing this project with the knowledge I get from day to day studying. I have a function in my views.py that communicates with an API and returns a result in Json. The result is basically this: [ { "_id": "5d6f28ec02523e0012a4eae6", "pass": false, "renderSatisfaction": false, "botTimeOut": false, "ignore": false, "exit": false, "errorslog": [], "chaterroslog": [], "Historic": [], "userID": "5b43b8a48b769470363b58909a9049", "user_key": "ABCD", "username": "Igor Miranda", "Created_at": "2019-09-04T03: 01: 00.716Z", "__v": 0 } { "_id": "5d6f291d55d3f500402d338e", "pass": false, "renderSatisfaction": false, "botTimeOut": false, "ignore": false, "exit": false, "errorslog": [], "chaterroslog": [], "Historic": [], "userID": "577a55a043aab2a6aa78586b2520392", "user_key": "ABCD", "username": "Igor Miranda", "Created_at": "2019-09-04T03: 01: 49.484Z", "__v": 0 } ] I need to render this result inside a table in an HTML page with Django, where I have the result of the fields "username", "username_key" and "history". I've read a lot of topics here on StackOverFlow, but I still can't solve my need.

How can i possibly make a dynamic REST API link of a Model that changes by id of another Model?
What i currently have setted up with django rest is : MODEL NAME : Animes /api/ <- root /api/animes/ <- lists all animes available in my db /api/animes/id/ <- returns the anime instance that has id=id MODEL NAME : Episodes /api/ <- root /api/episodes/ <- lists all episodes of all animes available in my db /api/episodes/id/ <- returns the episode instance that has id=id So basically im trying to achieve is : if i request api/episodes/{anime_name}/ i get that specific anime's Episodes listed . how can i do that ?

How can I add a class automatically in Django?
I would like that every time I create a form with django the tag input includes a specific css class (form-control), to do this I have to write in form.py the following code, adding lines for each field: class InsertItem(forms.ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['name'].widget.attrs.update({'class': 'form-control'}) self.fields['price'].widget.attrs.update({'class': 'form-control'}) Is there a way to force Django to include the css class that I need in every form, without having to write that things for each from and each line? -
Django save method is overwriting field values
I have a model that is overwriting a field value during the save opperation, I don't know if that happens during the communication with the database or its a pure Django problem. My bugged model: class Classificacao(models.Model): item = models.ForeignKey(Item, verbose_name="Item", db_index=True, on_delete=models.CASCADE, db_column='seq_prod') is_valid = models.BooleanField(default=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) In order to identify the bug I overwrited the save method: def save(self, *args, **kwargs): print(self.is_valid) super(Classificacao, self).save(*args, **kwargs) print(self.is_valid) When I created an instance of the class by the following code the overwrited 'save' prints the above: classificacao_nova = Classificacao.objects.create( item=item, created_at=datetime.datetime.now() ) Output: True False The problem gets worst: in other parts of the code the output is True True. Any ideas of what is going on? PS.: The database default for the is_valid column is 1. -
Nested JSON and HyperlinkedModelSerializer problem
I'm working on a tweet App. I have 2 main models : Tweets and Comments. I'm using HyperlinkedModelSerializer to get absolute url for my comments instances with the "url" added in the field. But when It comes to display the comments inside my tweet JSON format, i have this error : `HyperlinkedIdentityField` requires the request in the serializer context. Add `context={'request': request}` when instantiating the serializer. This error is gone when I remove the url from the field.

Django Post Request to Detail Page (Id)
I want to make a Django post request to specific url with a pk. So I have a list of projects and inside every project there are tasks. I want to add a task to that specific project. This is the View function to create a normal project: @login_required def create_project(request): if request.method == 'POST': name = request.POST.get('Studyplan-Name') description = request.POST.get('Studyplan-Description') parent_assignment = Assignment.objects.get(pk=request.POST.get('Studyplan-PAID')) usernames = request.POST.getlist('Studyplan-Canview') users = User.objects.filter(username__in=usernames) userprofiles = UserProfile.objects.filter(user__in=users) project = Project(name=name, description=description, parent_assignment=parent_assignment) project.save() project.canview.set(userprofiles) project.members.set(userprofiles) return redirect('allProjects') This is the project: When I tap this I get a detail page with a lot of tasks: This is a task: So as you can see every project has multiple tasks: This is my attempt at doing a post request to tasks.

Setted attribute with setattr is different type than given value in Python (Django)
Since ArrayField does not work with FileField in Django, I'm trying to fix it. However, I came up to a line of code, where I don't understand, how it happens, that setted attribute using setattr becomes different type than given value. To be exact - if I add print lines to code: print(data) setattr(instance, self.name, data or '') # line 317 print(getattr(instance, self.name) Here's what I get when I save a Model with FileField: <class 'django.core.files.uploadedfile.TemporaryUploadedFile'> <class 'django.db.models.fields.files.FieldFile'> What happens here? -
Google Vision API error when I push on Heroku
I have the following problem: I performed all the configuration as per Google Cloud documentation The credentials are validated and I can read the images by their url normally. It works fine, but only when it is on localhost, when it goes into production (heroku) does it simply stop working, returning error 503 - service unavailable. It makes no sense because in localhost it works perfectly. Do I need to set up something in my Google Cloud account or something? I really don't know what to do anymore. -
django create count subquery without groupby
I want to use a query thatn could be used as qubquery. But I noticed that query like this: x = Deal.all_objects.filter(state='created').values('id').annotate(cnt=Count('id')).values('cnt') produces SELECT COUNT("deals_deal"."id") AS "cnt" FROM "deals_deal" WHERE "deals_deal"."state" = created GROUP BY "deals_deal"."id" I dont need the GROUP BY, I jost want to count offers that match filter.

How change urls dynamically based on chosen language prefix
I have 2 languages in Django project. Base is site/pl/ and 2nd is site/en. There are also 2 buttons in header.html to switch language (add prefix to url). String translation works fine. My problems are: 1. When I switch(click button) between languages I want to load home page because right know it works only when I am at home page - so if I move to any subpage and click to language button it reload same page (not home). 2. When I switch between languages I want to change also subpages urls to right names. I try some weird way to made this: <li><a href="{{baseurl}}">PL</a></li> <li><a href="{{en_url}}">EN</a></li> and then in views: def index(request, *args, **kwargs): baseurl = '/' en_url = baseurl + 'en' return render(request, 'home.html', {'baseurl': baseurl, 'en_url': en_url}) But I assume it's bad.

Overriding Django admin inlines formset will not save more than 1 row
I have a straight forward admin.ModelAdmin class with an inlines, of which I am overriding the form and formsets with a forms.Model and BaseInlineFormset to add a custom field. I have a custom jQuery script that gets loaded in and whenever a machine is picked from the select2 drop-down it runs an AJAX query to the REST API and grabs the items based on a foreign key value and populates the CleaningEntryInline with information.

Is there a better way to write output of background tasks to the database?
first of all thx for reading. In my project, I have azure-function / azure webjob to do the parsing，analysis of the raw data when it comes to the storage account. The output will be update to database with direct sql command like: sql_update = """UPDATE "PrototypeOne" SET files_amount =%s, used_time = %s where "User_Name" =%s;""" cursor.execute(sql_update,vars) My questions are: 1, is there a smarter way to update the database? can my backend play some role in between? 2, Is there a pub/sub library for such 'script level' application?

connect assets uploaded in anonymous mode post login
I am building a web app where user can upload a file in logged out mode but expects the file to be associated with him post login in the same session. The way I have implemented is to attach both a session_key and a User to the model as follows class Asset(Model): id = BigAutoField(primary_key=True) file = FileField(upload_to=get_file_path) submission_time = DateTimeField(auto_now_add=True, blank=False) expiration_time = DateTimeField(default=some_method) session = CharField(max_length=1024) user = ForeignKey( User, on_delete=CASCADE, related_name="%(app_label)s_%(class)s_related", related_query_name="%(app_label)s_%(class)ss", blank=True, null=True) def __str__(self): return self.file.name When the user first uploads the Asset, I capture the same and store it in backend with session_key. Once users confirms his willingness to post this Asset to share with community by doing signup/login, I match the Asset's session key with current session key and updates the user field in the Asset model. Is this the best approach? Does this approach have any security loopholes here? -

Is it safe to use auth_user for regular website users?
I want to create a website where people can post things using accounts. It should also be possible to login with google (or other) OAuth, where I would basicly create an auth_user for them using googles tokens. So is it safe to use djangos preexisting user and group system for regular everyday users of my website by just denoting them without staff or superuser priviledges? Also can I just link the google token to an auth_user and start a session for him that way? Or should I implement my own user and group system? -
