Django custom user model meta overlaps when importing from another project
I'm remaking a script to sync data from an old python2 project to a new with python3. The way the last programmer made it work appears to be by importing both, the new and old models into a script in the old project using: sys.path.append("route to the new project") It works for importing every model except for a custom user model from the new project, when I try to work with it, like using UserProfile.objects.all() it crashes with: relation "user_userprofile" does not exist LINE 1: SELECT "user_userprofile"."id" FROM "user_userprofile" The right table is user_models_userprofile, because the app containing the model is "user_models" instead of "user". The app_label from the imported model shows "user", which is probably the default app_label when extending AbstractUser, it is probably ignoring the app_label attribute from my model and using the one from AbstractUser. Any ideas of how to make it work? Also sorry for my english. -

A user can manually edit another user view from URL
I just noticed that a user can manually access another users update profile view by changing to the other users pk or username(as slug) in the URL. for instance http://127.0.0.1:8000/account/dashboard/18/updateprofile Lets say that is the users update profile url, if this user changes the pk to 19 and edit, the user with pk 19 profile will be edited, is this a bug or is this an error from my side? Thank you. -
Changed DB engine to MySQL. Now Django does not create tables
I have a Django app with a standard sqlite3 DB. Now I want to use MySQL. So I changed my DATABASES in settings.py, and it works well, but I can't run server because it says django.db.utils.InternalError: (1049, "Unknown database 'django'") So I created this DB in the client, and now it says django.db.utils.ProgrammingError: (1146, "Table 'django.Cat' doesn't exist") Seems like I have to create all tables by myself, which is the worst variant I can do. #settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'OPTIONS': { 'read_default_file': '/path/to/db.conf', }, } } and #conf.db [client] database = django host = localhost user = DjangoUser password = password_you_cant_guess default-character-set = utf8 How to make Django create all tables I have? I even can't run python3 manage.py with any command because it gives my this exception. -

Django inlineformset_factory and ManyToManyField field, once again
first of all, sorry for my English! I have a little problem with "inlineformset_factory" and "ManyToManyField". Perhaps the option "inlineformset_factory" isn't the right choice. I have two classes, Prodotti and Categoria. In models.py are class Categoria(models.Model): ''' tabella delle Categorie dei prodotti ''' NomeCategoria = models.CharField(max_length=50,blank=True,null=True) class Prodotti(models.Model): ''' tabella Prodotti a catalogo ''' NomeProdotto = models.CharField(max_length=50,blank=True,null=True) CategoriaProdotto = models.ManyToManyField(Categoria, related_name='prodotti_categoria') I need a form to modify the name of a specific Categoria, es. Antiossidante, and eventually change the list of Prodotti that have this Categoria. I try a lot with "inlineformset_factory" and the use of "Prodotti.CategoriaProdotto.through" but I have problems with fields, only "id" is accepted. i.e. ProdottiFormset = inlineformset_factory(Categoria, Prodotti.CategoriaProdotto.through, fields=('id',)) But, changing the name of Categoria it isn't saved. This is my project: views.py def ModificaCategoria(request, pk): # recuperiamo la categoria da modificare, bisogna passare l'ID categoria = get_object_or_404(Categoria, pk=pk) ProdottiFormset = inlineformset_factory(Categoria, Prodotti.CategoriaProdotto.through, fields=('id',)) if request.method == "POST": form = CategoriaModelForm(request.POST, request.FILES, instance=categoria) formset = ProdottiFormset(request.POST, instance=categoria) if formset.is_valid(): formset.save() return render(request, "dopo_modifica_categoria.html") # return redirect(...) else: categoria = Categoria.objects.get(pk=pk) form = CategoriaModelForm(instance=categoria) formset = ProdottiFormset(instance=categoria) context = { "form": form, "formset": formset, } return render(request, "modifica_categoria.html", context) Template: {% extends 'base.html'%} {% block head_title %}{{ … -

Django - safely render HTML in template

Whats the difference between models and models.Model in django?(and similarly for forms and forms.Form )
I know that "models" is a module of package django.db, But why we inherit like class Foo(models.Model): while the all required fields like CharField, IntegerField, etc. are part of models, what does the subclass Model do here exactly? I am new to OOP and Django so any resources and answers are heavily appreciated and welcomed. -

is there any reason i cannot register and then login user in the same function using Angular and Django?
Using Angular and Django. When a user registers I want them to be automatically logged in and sent to their homepage. I have a registerUser function in my UserApiComponent that looks like: registerUser(){ this.userApiService.createuser(this.register).subscribe() this.user_cred = { username: this.register.username, password: this.register.password } console.log(this.user_cred) this.userauthcomponent.login(this.user_cred) } In my UserAuthComponent my login function is: login(user_cred){ this.authenticationService.login({'username': this.user_cred.username, 'password': this.user_cred.password}).subscribe( resp => { let response = resp; this.user_id = response.user_id this.router.navigateByUrl('/dashboard/'+this.user_id) }); } From my regular login page the login function works completely fine and I am able to login a user. From my registration page I am able to easily register a user. However, when I try to register AND login a user at one time so that the user does not have to login after registering I keep getting a bad request error: *core.js:6014 ERROR HttpErrorResponse {headers: HttpHeaders, status: 400, statusText: "Bad Request", url: "http://127.0.0.1:8000/users/api-token-auth/", ok: false, …} error: non_field_errors: ["Unable to log in with provided credentials."]* I know the credentials are correct because the console.log is outputting the correct info.

Django ForeignKey for multiple models with reverse relation
I'm currently working on a project where I have to assign values for certain instances while not affecting them. To give an example let's assume its a multi-service shop and we have a shopping cart where I have to put an Item order so I need ForeignKey to item ForeignKey to cart quantity the item but the item can be either product or service and cart can be a normal or special (two different models in both cases). I know how to achieve it but the thing that I couldn't obtain is the ability to call the item_order from for example product instance that its linked to. I'd be glad if anyone can either help me achieve the goal or show me another approach on the problem.

Reset password after first successful login
I am building an web application using existing Auth features in Django where admin create user profile with username and password. Admin created user name and password will be given to user to login. So for security reasons I need to ask user to reset password (given by admin) after user's first successful login. To reset password, I will be displaying template where user should be entering only new password and new password again for confirmation. This new password will be updated in sqlite database. So whenever admin changes the users password. I need to ask users to reset password after first successful login. Here are the implementation I have done. models.py: Here I set boolean flag profile.force_password_change to TRUE when new user created.

I have viewset with cache like this on off by changing False -> True def maybe_decorate(condition, decorator): return decorator if condition else lambda x: x class TweetViewSet(viewsets.ModelViewSet): queryset = Tweet.objects.all().order_by('id') serializer_class = TweetSerializer filter_class = TweetFilter @method_decorator(cache_page(60*60*2)) @method_decorator(vary_on_cookie) @maybe_decorate(False,method_decorator(cache_page(60*60*2))) @maybe_decorate(False,method_decorator(vary_on_cookie)) Then now I have one idea.

DRF Serializer update method always has empty validated_data object when using PATCH + multipart/form-data
I've been banging my head about this one for a bit as I seem to be missing something obvious in this issue. First off, I have multiple parsers loaded for my DRF setup in settings.py: REST_FRAMEWORK = { 'DEFAULT_PARSER_CLASSES': ( 'rest_framework.parsers.JSONParser', 'rest_framework.parsers.FormParser', 'rest_framework.parsers.MultiPartParser', ), } Given the presence of the MultiPartParser I would presume that DRF should be parsing the body correctly. However in my ModelSerializer I am overriding the update handler to handle the files and attach them to the model, however all the fields are empty when I interate through them, even the basic ones like 'id' - however I know it must be interpreting the data, because the correct instance is loaded every time, in this case it's the user that is being updated. class UserSerializer(ModelSerializer): """ Serializer for the Logged in User """ avatar = VersatileImageFieldSerializer( sizes='member_avatar' ) background = VersatileImageFieldSerializer( sizes='member_background' ) class Meta: model = Member fields = ( 'id', 'email', 'username', 'language', 'bio', 'location', 'homepage', 'avatar', 'is_staff', 'groups', 'background', 'created', 'edited', 'last_login', 'slug', 'signature' ) read_only_fields = ['created', 'edited', 'slug'] def update(self, instance, validated_data): """ Update the user. :param instance: user instance :param validated_data: validated form data :return updated user """ updated_fields = … -

How can I use React.lazy with Django and Webpack 4?
I am building app with django on the backend and react on the frontend. I would like to use React.lazy, but I have some problems with Django, because it can not find other bundels except main.js which I have added to index.html template. This is my Webpack configuration: const HtmlWebpackPlugin = require('html-webpack-plugin'); module.exports = { entry: './src/index.js', output: { path: __dirname + '/dist', filename: 'index_bundle.js' }, plugins: [ new HtmlWebpackPlugin() ], module: { rules: [ { test: /\.js$/, exclude: /node_modules/, use: { loader: "babel-loader" } }, { test: /\.css$/i, use: ['style-loader', 'css-loader'], }, { test: /\.(png|jpe?g|gif)$/i, use: [ { loader: 'file-loader', }, ], }, ] } }; Django view: def index(request): return render(request, 'frontend/index.html') index.html {% load static %} <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="shortcut icon" href="{% static 'frontend/favicon.ico' %}" type="image/x-icon"> <link href="https://fonts.googleapis.com/css?family=Oswald&display=swap" rel="stylesheet"> <title></title> <link rel="stylesheet" href="{% static 'frontend/bootstrap.min.css' %}" /> </head> <body> <div id="app"> <!-- React will load here --> </div> </body> <script src="{% static "frontend/main.js" %}"></script> </html> React app: class App extends Component { componentDidMount() { store.dispatch(loadUser()); } render() { return ( <Provider store={store}> <AppRouter /> </Provider> ); } } and AppRouter const AsyncHome = React.lazy(() => import(/* webpackChunkName: "Home" */ …
