how to pass a list of dictionary in chartjs labels and data?
I'm trying to show my data into chart js graph, my data format is this: > {length: 3, objects: Array(3)} length: 3 objects: Array(3) 0: {counter: 1, date: '2022-06-01 00:00:00', income: '233.000', …} 1: {counter: 2, date: '2022-05-01 00:00:00', income: '1000.000', …} 2: {counter: 3, date: '2022-04-01 00:00:00', income: '89.000', …} length: 3 [[Prototype]]: Array(0) [[Prototype]]: Object here is what i tried in my js: function listChartMonOutcome(){ $.ajax({ type:'GET', url:'/listcharts/data/', success:function(data){ var totalMonthCanvas = $('#listChart').get(0).getContext('2d') var totalMonthData = { labels: [ data ], data:{ datasets:[{ data:[{ data }] }] } } var totalMonthOptions = { responsive : true, maintainAspectRatio : false, datasetFill : false, parsing: { xAxisKey: 'income', yAxisKey: 'date' } } var totalMonthChart = new Chart(totalMonthCanvas, { type: 'bar', data: totalMonthData, options: totalMonthOptions }) } }) } listChartMonOutcome() } <div class="card-body"> <div class="chart"> <canvas id="listChart" style="height:250px; min-height:250px"></canvas> </div> </div> but it shows nothing, in the console as well. and also tried this in the data : labels = [data.map(({datE}) => date) ] datasets: [ { data: [ data.map(({income}) => income) ], } ] but raise this error: Uncaught TypeError: data.map is not a function is there any solution for this problem please? Thank you for helping -
Directing to nested URL with react router from server
I am building an app with django3.2 and React 17 using react-router-dom. My react app is served at https://www.example.com/ And if I navigate within the app to https://www.example.com/auth/signup I get the form, however, if I input the url directly into the browser I am taken to a blank page. In my django.urls, I have a catch all that should send the path down to my react app, and in local development it works great. urlpatterns = [ ..., re_path(r'^(?:.*)/?$', homepage), ] PROBLEM: In production I am taken to a blank page. I suspect it has to do with relative paths in production. I've followed these questions: Django static file serving in conflict with React Router React router not loading dynamic url in production And so far have tried: Adding "homepage": "https://www.example.com/" to my package.json. Adding <base href="/" /> to index.html Adding "homepage": "." to package.json But so far nothing has worked, and I need this feature, particularly for email verification. Happy to clarify anything or share front end code. -
What to do if queryset is none
I have a News model, where each instance has a unique date. Which means that every day has exactly one News-instance related to it. I am redirecting to the detail-view of the News-instance from the navbar. To achieve this am I using a context_processor. The context_processor.py file looks like this: from news.models import TodayNews import datetime def todays_news(request): todays_news = TodayNews.objects.get(date=datetime.date.today()) return {'news': todays_news} This works completely fine as long as the News model has an instance on that particular date. Otherwise it returns the following error (which is very logical): TodayNews matching query does not exist. My question is, how can I do something different if the query is empty, for example if one particular date does not have a news-instance? What should I return instead of 'news': todays_news? -

Nested Serializer for Foreign Keys

Vertically centering text in a bootstrap card that is being used as a button
As the title says, im trying to vertically align text inside a bootstrap card. I can center it horizontally just fine, just not vertically. I've tried different ways. I would use a button but you can't store links in them I guess. Here is some code <div class="col-sm-4"> <a href="{% url 'manufacturing:view_sections' %}" class="btn btn-primary lift lift-sm h-100 w-100 text-center" style="width: 100vw;" role="button" aria-disabled="true"><h1 class="text-light"><strong>Primary link</strong></h1></a> </div> Here is what it looks like right now The whole card is being used as a button which when pressed it's sent to a different page. -
Is separating django frontend and backend with API viable?
I'm used to Django and already developed website with a whole Django or with Django API + React. For a side project, I'm thinking about creating a Django project with 2 apps: Django API 2) Django Front. I absolutely want to decouple front/back to be able to reuse the API in the future, and I like the view system from Django. Is my idea making sense? -

How to use django-allauth username validation methods in a user update form
I'm using django-allauth system to register users and log them in. My app should allow users to change their usernames if needed. If I use a custom view or form to change a username, no allauth validation happens whatsoever (because default views and forms are not triggered). Thus users can easily set whatever username they wish, ignoring all restrictions specified in settings (like "preserve casing" or "minimum length restriction"). Is there any way to use default validations built in allauth outside signup/login forms? Right now I have to manually create a custom form and use its cleaning methods for validation, which seems to be repetitive and error-prone: def clean_username(self): username = self.cleaned_data.get('username') if username: username = username.lower() if len(username) < settings.ACCOUNT_USERNAME_MIN_LENGTH: raise ValidationError(_("Error text")) if username in settings.ACCOUNT_USERNAME_BLACKLIST: raise ValidationError(_("Error text")) # I need something that works like the code below and validates a username from allauth.account.adapter import DefaultAccountAdapter DefaultAccountAdapter.clean_username(username) return username -

Django: Handle migrations created in site-packages for a custom Group field
I require a description field added to the django.contrib.auth.models.Group, so I used this solution (if there is a better way please let me know): from django.contrib.auth.models import Group Group.add_to_class('description', models.TextField(max_length=250, default="")) Unfortunately this creates a migration in: site-packages/django/contrib/auth/migrations/0013_group_description.py This is the migration: class Migration(migrations.Migration): dependencies = [ ('auth', '0012_alter_user_first_name_max_length'), ] operations = [ migrations.AddField( model_name='group', name='description', field=models.TextField(default='', max_length=250), ), ] This can't be checked into source code since it's in the python site-packages location. I managed to find the MIGRATION_MODULES setting, but unfortunately I don't wish to move all of the auth app's migration to a new dir (django comes with 12 migrations already for auth, and may ship more in the future. No idea how to solve this problem. It really makes deployment a nightmare. -

Django Viewset ADD header to requests
I have two APIs that talk to each other. One API is on DRF, where it needs to take a one-time generated token and pass it with every request to the second API. I can find ways to add headers to the response, but I don't see anyway with a Viewset to pass a token into the header of ALL my requests. I can only find default_response_headers but default_request_headers doesn't exist. I'm also only finding how to respond with a token and take in a request with a token. To clarify, I do not need to get a request header, I need to add a request header with every request on my Django project. Django REST API ---- request w/ token ----> other system -
Python requests makes a lot of post requests, what should I do?

How to save mapped values based on Foreign key (amount can vary)
