Django 2.0.2 - Many To Many Relation - Can't get IDs
I've been trying to develop a webapplication with Django 2.0.2 including Full Calendar and Bitnami Stack. I seem to not comprehend the Many-to-Many relationship in Django. Currently I am attempting to match all fitting resourceIds with each corresponding event (called termin in this case): views.py: def events(request): terminList = Termin.objects.all() termine = [] for termin in terminList: termine.append({'title': termin.beschreibung, 'start': termin.startzeit, 'end': termin.endzeit, 'resourceId': str(termin.teilnehmer_betreuer.all()) ## Trying to get a Resource ID here ## }) return HttpResponse(json.dumps(termine, cls=DjangoJSONEncoder), content_type='application/json') models.py: class Termin(models.Model): GRUEN = 'GR' GELB = 'GE' ROT = 'RO' UEBERSCHREIBBARKEIT_AUSWAHL = ( (GRUEN, 'Überschreibbar'), (GELB, 'Auf Anfrage'), (ROT, 'Nicht Überschreibbar'), ) startzeit = models.DateTimeField(default=datetime.datetime.today) endzeit = models.DateTimeField(default=datetime.datetime.today) beschreibung = models.TextField(max_length=400) teilnehmer_patient = models.ManyToManyField(Patient) teilnehmer_betreuer = models.ManyToManyField(Benutzer) ueberschreibarkeit = models.CharField( max_length=25, choices=UEBERSCHREIBBARKEIT_AUSWAHL, default=GRUEN, ) raum = models.ForeignKey(Raum, on_delete=models.SET_NULL, null=True) def __str__(self): return self.beschreibung The json I get: [{"title": "Test", "start": "2018-02-09T06:57:23Z", "end": "2018-02-09T07:20:00Z", "resourceId": "<QuerySet []>"}, {"title": "Test", "start": "2018-02-09T13:05:59Z", "end": "2018-02-09T13:05:59Z", "resourceId": "<QuerySet [<Benutzer: doktor>, <Benutzer: joschmidl>, <Benutzer: skywalker>, <Benutzer: qsdasdsada>]>"}, {"title": "Taesaed123", "start": "2018-02-09T13:06:21Z", "end": "2018-02-09T13:06:21Z", "resourceId": "<QuerySet [<Benutzer: doktor>, <Benutzer: joschmidl>, <Benutzer: skywalker>, <Benutzer: qsdasdsada>]>"}] This is the extra table, which is not in my models.py, that Django creates after migrating my database. id,termin_id,benutzer_id 7,2,2 8,2,4 … -

Django ASGI New Relic CORS Error Heroku
I am running a Django Application using Django channels and a daphne server (ASGI) instead of the typical gunicorn (WSGI) server. So I had to modify my application to this: # asgi.py import os import django from channels.routing import get_default_application from asgiref.wsgi import WsgiToAsgi from django.core.wsgi import get_wsgi_application from newrelic import agent os.environ.setdefault("DJANGO_SETTINGS_MODULE", "server.settings") django.setup() application = agent.WSGIApplicationWrapper(get_wsgi_application()) application = WsgiToAsgi(application) To my surprise this actually works. When I access my django api from a browser or postman it works properly and the data shows up in New Relic. However, I also have a client-side Angular web app which makes REST API calls to the django server and I am getting CORS errors. Please note that this is not a regular CORS issue as when I remove the new relic wrapper I am able to access my API properly from Angular. Failed to load https://my-app.herokuapp.com/api/: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin https://frontend.com is therefore not allowed access. -
how to get history of an object in django?
I use django 1.11 and I have a book model: class Book(models.Model): user_borrowed = models.ForeignKey(User, null=True) name = models.CharField(max_length=100) description = models.TextField() author = models.CharField(max_length=30) isbn = models.CharField(max_length=80) def borrow_book(self, user): if self.user_borrowed is not None: return False self.user_borrowed = user self.save() def return_book(self): self.user_borrowed = None self.save() it's like a library system. all I want to do is to know which users borrowed a special book. in fact all users. for example I want to get this result: [ { "username": "user_name_1", "date": "2018-02-08T14:13:22.142497"}, ] this means that user_name_1 borrowed this book at the above time. so how to do this ? thank you. -
How to prevent my frontend to make favicon request?
I am using next Js for my frontend and django rest framework in the backend. I'm facing an issue when i do a request between them : My frontend actually make two requests. The normal request as expected but also a strange favicon.ico request and this generating multiple errors. I could handled it by asking my server to ignore all request with favicon value, however, when i make a redirect from the frontend (next.js), getinitialprops only send favicon.ico and impossible to get the expected params from my request. I get a network error and I have to manually refresh the page. I created a favicon directory both in nextjs and django, i verified the path url is okay i don't understand. Any solution ? -
Django - Unsupported operand type(s) for decimal and method

jQuery adding extra variables to url
I think this is problem on frontend, and I am not familiar with frontend. So, this might not be the best method, suggestions are most welcome. I need to get some data from a rest api developed via django-rest-framework and put it into the input field on a form. So, this is the code, function getcharmids(){ var get_url = "http://localhost:8000/get_charm_ids/" + name; # name I am declaring in the django template console.log('clicked'); $.ajax({ type: 'GET', dataType: "json", url: get_url, contentType: "application/x-www-form-urlencoded;charset=UTF-8", accept: "application/json", success: function(data){ var charm_input = document.getElementById('id_charm_ids'); console.log(charm_input.value); charm_input.value = data.charm_ids; }, }); }; So, it does call the URL, but with extra parameters. It should call http://localhost:8000/get_charm_ids/Kasam09 But it calls with /get_charm_ids/Shakti_02?callback=jQuery111009547658997639622_1518179689207&_=1518179689208 So, due to extra parameters, my backend cannot process this request. What is the workaround to this problem? What is the correct way to call apis via jquery? Or is there any another good method? -
Concatenate Django urls with parameters as href
I got a template where i send a queryset of this model: Id Item Url 1 Sales "{% shop:sales product.id %}" 2 Payroll "{% shop:payroll area.id type.id %}" . . . And so on... In that template i need to iterate this model items setting each item url as a href, as you can see each url it's different and receive a diferent ammount of parameters, so, i defined the url field in the model as a string and try it: <table class="table table-condensed"> {% for item in items %} <tr> <td>{{ item.name }}</td> <td><a href="{{ item.url }}">Go</a></td> </tr> {% endfor %} </table> Of course, i send product, area and type via context from the view too. But it doesn't work, already tried also: href={{ item.url }} -- with no "" And concatenating the url removing the parameters from the string in the model field to use it like this then: href= "{{ item.url }} + product.id" Any idea ?, thanks in advance. -
