Accessing self-referencing field in Django
I have class User, with field friends class User(AbstractUser): USERNAME_FIELD = 'username' REQUIRED_FIELDS = ['password'] username = models.CharField(max_length=30, unique=True) password = models.CharField(max_length=100) friends = models.ManyToManyField('self') when I migrated class to database, it created two tables. app_user and app_user_friends app_user in itself has no reference to friends, but app_user_friends has id of a user, and id of a friend. The issue is: qhen I try to access friends of a user by calling user = models.User.objects.get(id=user_id) print(user.friends) I get app.User.None Should I be calling it differently or is there something wrong with the model? -

Using Django in AWS lambda
I'm writing a simple http server in aws lambda and would like to use Django, however I'm not looking to deploy an entire django app on lambda through zappa. Is there any way to just import django's HttpResponse library in a lambda function like below? from django.http import HttpResponse def lambda_handler(event, context): # TODO implement msg = "hello its me" return HttpResponse(msg, content_type='text/plain') I've already created a deployment package with all the django libraries inside and uploaded to lambda, but I'm getting an error: Requested setting DEFAULT_CHARSET, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.: ImproperlyConfigured any help is appreciated, thanks in advance! -
Struggling with Class Based Form Django (save foreign key attributes)
I have imported my MySQL DB to Django. In this DB, I have an intermediate table called GroupUsers which links User and GroupName. I would like to make a form where I can fill in the user attributes and add it directly to a selected group. So basically we have an user form with an extra field corresponding to the groups that I need to select among three categories: family, friends, pro. I'm not able to make it work. #models.py class GroupUsers(models.Model): group = models.ForeignKey(GroupName, on_delete=models.CASCADE) user = models.ForeignKey('User', on_delete=models.CASCADE) class Meta: managed = False db_table = 'group_users' unique_together = (('group', 'user'),) def __str__(self): return self.group.name class User(models.Model): email = models.CharField(unique=True, max_length=180) last_name = models.CharField(max_length=32) first_name = models.CharField(max_length=32) class Meta: managed = False db_table = 'user' verbose_name = "user" def __str__(self): return self.first_name class GroupName(models.Model): group_id = models.AutoField(primary_key=True) name = models.CharField(max_length=32) description = models.TextField(blank=True, null=True) class Meta: managed = False db_table = 'group_name' verbose_name = 'Group' def __str__(self): return self.name #forms.py class UserCreateForm(forms.ModelForm): class Meta: model = User fields = ('first_name','last_name', 'email') def __init__(self, *args, **kwargs): super(UserCreateForm, self).__init__(*args, **kwargs) self.fields['group'] = forms.ModelChoiceField(queryset=GroupName.objects.all()) #view.py class UserCreateView(SuccessMessageMixin, LoginRequiredMixin, CreateView): template_name = 'dashboard/users/user_create_form.html' model = User form_class = UserCreateForm def get_object(self, queryset=None): obj … -

Django - Models category error in Admin: “Select a valid choice. That choice is not one of the available choices”
So I am trying to build a recipe field in django-admin. I have a Model category called Meals and I have categories to chose from on the admin page but as soon as I try to save my entry, I get the Select a valid choice. Breakfast is not one of the available choices & prevents me from saving anything. I've tried moving the daily_meals value from Recipe Field into Meal Category and uncommenting the first meal and commenting the second value in Recipe Field.

In Django, how do I render fields of fields from a queryset in JSON when sending a response from an AJAX view?
I'm using Django 2 with Python 3.7. In my view, I have this code for sending JSOn to an AJAX call ... articlestat_query = ArticleStat.objects.get_stats() ... data = { 'articlestat': serializers.serialize('json', list(articlestat_query)), ... } return JsonResponse(data) The query "articlestat_query" pulls models that look like this ... class ArticleStat(models.Model): objects = ArticleStatManager() article = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='articlestats') elapsed_time_in_seconds = models.IntegerField(default=0, null=False) score = models.FloatField(default=0, null=False) The issue is when my JSON is generated, the "article" piece gets returned as "article" and its numeric primary key, e.g. "article": 12345678 How do I configure my serialization so that the JSON of that field is rendered instead of its primary key. IOW, the JSON would be "article": {"title": "hello world", "author": "George Costanza" ... -

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?

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.

MODELS class MedicalInfo(models.Model): BLOOD = ( ('A+', 'A+ Type'), ('B+', 'B+ Type'), ('AB+', 'AB+ Type'), ('O+', 'O+ Type'), ('A-', 'A- Type'), ('B-', 'B- Type'), ('AB-', 'AB- Type'), ('O-', 'O- Type'), ) @staticmethod def toBlood(key): for item in MedicalInfo.BLOOD: if item[0] == key: return item[1] return "None" patient = models.ForeignKey(User, on_delete=models.CASCADE, related_name="patiento") bloodType = models.CharField(max_length=10, choices=BLOOD) allergy = models.CharField(max_length=100) alzheimer = models.BooleanField() asthma = models.BooleanField() diabetes = models.BooleanField() stroke = models.BooleanField() comments = models.CharField(max_length=700) def __str__(self): return f'{self.user.username} Medinfo' def save(self): super().save() VIEWS.PY class MedinfoCreateView(LoginRequiredMixin, CreateView): template_name = 'all_users/public/medinfo.html' model = MedicalInfo fields = ['bloodType', 'allergy', 'alzheimer', 'asthma', 'diabetes', 'stroke', 'comments'] def form_valid(self, form): form.instance.patient = self.request.user return super().form_valid(form) HTML {% extends "base.html" %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4"> Medinfo </legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit"> … -
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. I also tried just putting all the login logic inside of the registerUser function as follows: registerUser(){ this.userApiService.createuser(this.register).subscribe() this.user_cred = { username: this.register.username, password: this.register.password } this.authenticationService.login({'username': this.register.username, 'password': this.register.password}).subscribe( …
