Why does random in django rest serializer always return the same field?
I have a simple serializer class Serializer(serializers.Serializer): name = serializers.CharField(required=False, default='someName') id = serializers.IntegerField(required=False, default=random.randrange(100, 200)) And when I create multiple instances of the serializer it always returns the same field a = Serializer(data={}) a.is_valid(data={}) data = a.data data['id'] // return for example 150 b = Serializer(data={}) b.is_valid(data={}) b_data = b.data b_data['id'] // return also 150 Why it happens?

Line chart by dates with django models
I’m trying to build a line chart using Chart.js and Django. This chart will shows the account of class “anomalies” per month. The class anomalie has date_report attribute. This date will repeat because there are many anomalies that could happen in the same month. So I need to group them per month and count the amount of anomalies in this month, then I need to show this in a graph, in order to see the historic progress: In X the month and In Y the amount of anomalies To achieve that in my view.py I have trunked by month months and count by id count_per_month like this: @login_required(login_url='login') def home_screen_view(request): context = {} user_aisles = request.user.aisle.all() list_anomalies_user = [] anomalies = Anomalie.objects.all() anomalies_per_aisle = anomalies.filter(aisle__in=user_aisles) # line chart months = anomalies_per_aisle.annotate( month=TruncMonth('date_report')).values('month').annotate(c=Count('id')).values('month') count_per_month = anomalies_per_aisle.annotate( month=TruncMonth('date_report')).values('month').annotate(c=Count('id')).values('c') print('months', months) print('count_per_moth', count_per_month) context = {'list_anomalies_user': list_anomalies_user, 'anomalies_per_aisle': anomalies_per_aisle,'count_per_month': count_per_month, 'months': months} return render(request, "personal/home.html", context) Then I’m passing this data to "labels" and "data" into the scripts using “safe” like this: <script> var ctx = document.getElementById("myAreaChart"); //"myAreaChart" var myLineChart = new Chart(ctx, { type: 'line', data: { labels: [{{ months| safe}}], datasets: [{ label: "Sessions", lineTension: 0.3, backgroundColor: "rgba(2,117,216,0.2)", borderColor: "rgba(2,117,216,1)", pointRadius: … -
Calling a Django function inside an AWS Lambda

Email verification is not enforced. Disregarding ACCOUNT_EMAIL_VERIFICATION setting
I'm using two packages to assist me with authentication. One is js_rest_auth and the other one is allauth. The latter has a setting to require users to validate their email addresses before a login is possible. I'm setting ACCOUNT_EMAIL_VERIFICATION = "mandatory" but it has no effect. My relevant settings look as follows: INSTALLED_APPS = [ ... "django.contrib.sites", "rest_framework.authtoken", "allauth.account", "allauth.account", "allauth.socialaccount", "dj_rest_auth", .... ] ACCOUNT_EMAIL_VERIFICATION = "mandatory" ACCOUNT_EMAIL_CONFIRMATION_EXPIRE_DAYS = 90 ACCOUNT_USER_MODEL_EMAIL_FIELD = "email" ACCOUNT_AUTHENTICATION_METHOD = "email" ACCOUNT_EMAIL_REQUIRED=True ACCOUNT_UNIQUE_EMAIL = True ACCOUNT_USERNAME_REQUIRED=False ACCOUNT_USER_MODEL_USERNAME_FIELD = "email" ACCOUNT_PRESERVE_USERNAME_CASING = False ACCOUNT_ADAPTER = "users.accountadapter.CustomAccountAdapter" AUTHENTICATION_BACKENDS = [ 'django.contrib.auth.backends.ModelBackend', 'allauth.account.auth_backends.AuthenticationBackend', ] REST_FRAMEWORK = { .... "DEFAULT_AUTHENTICATION_CLASSES": [ "rest_framework.authentication.TokenAuthentication", ], "DEFAULT_PERMISSION_CLASSES": [ "rest_framework.permissions.IsAuthenticated", ] } The users I create aren't verified (verified attribute an Email Address Model) but are created with is_active=True. When I send a login request for a non-verified user, a valid token is issued. -
How to run python script as daemon/cronjob in Django?
I have developped a Django app and try to solve what should be simple... but more I read about this and more it seems to be complicated. I want an email to be send to new user each time new user account is created in auth_user. I first thought about signals and it works but not when I execute a sql script to create user account.

Django form ChoiceField not selected when editing existing instance
I'd like to design a modelform that has a choicefield field with values that depend on the value of another field of the same form. For the sake of example, here is the modelform. The course day can be selected for each full-day course. For example, if the user has chosen MATH101, the course_day choicefield should give them a different set of days than if the user has chosen a CMPT101 course: class CourseFeeForm(ModelForm): class Meta: model = Course fields = ['course_name', 'course_day',...] def __init__(self, *args, **kwargs): super(CourseFeeForm, self).__init__(*args, **kwargs) if self.instance and self.instance.course_name == 'CMPT101': self.fields['course_day'] = forms.ChoiceField( choices= ( ('monday', 'Monday'), ('tuesday', 'Tuesday') ) elif self.instance and self.instance.course_name == 'MATH101': self.fields['course_day'] = forms.ChoiceField( choices = ( ('monday', 'Monday'), ('wednesday', 'Wednesday'),('friday', 'Friday')) ... The problem is that in the template for the edit view, I'd like the form to display what the user already selected, but if the user has selected Monday as the course_day, the <option value="monday">Monday</option> is missing the selected="selected" presumably because in __init__, we have changed the choicefield based on the course_name and so the default behavior of attaching the selected="selected" to the already selected option is overriden.

Django - Display success messages for 10 or 20 seconds in Django Admin Panel
I was working in Django admin. So while saving a modal there is an automatic success message that appears after saving. I was wondering if it is possible to set the time limit for the message to appear. So that after few seconds it deletes automatically!! In the picture below after creating a project and saving it there is a success message which says "The project 'xyzproject' was added successfully". But this message remains on the page until I refresh the page. so can anyone tell me if its possible to add a time limit for the message to appear and disappear without refreshing the page. -
