React Redux Django REST API: How to properly detail an object
I am using React / Redux with the Django REST API. Still learning, so please give pointers. I am trying to return an object by id and display its properties. Here is my viewset for the objects that I am trying to interact with: class ViewsetCSVFile(viewsets.ModelViewSet): queryset = CSVFile.objects.all() permission_classes = [ permissions.IsAuthenticated ] serializer_class = SerializerCSVFile def get_queryset(self): return self.request.user.csv_files.all() def perform_create(self, serializer): serializer.save(author=self.request.user) def retrieve(self,request,*args,**kwargs): obj_id = kwargs['pk'] obj = CSVFile.objects.get(id=obj_id) serialized = self.get_serializer(obj) return Response(serialized.data) In my actions.js file, here is the action to get a file by id: // GET FILE by ID export const getCsvFile = (id) => (dispatch,getState) =>{ axios.get(`/api/csv/${id}/`,tokenConfig(getState)) .then(res => { console.log(res); dispatch({ type:GET_CSV_FILE, payload:res.data }) }) .catch(err=> { dispatch( returnErrors(err.response.data,err.response.status)) console.log(err); } ) } Here is the page to display the object on the front end: import { useParams } from "react-router-dom" const CsvFileDetail = (props) => { const propTypes = { csvFiles: PropTypes.array.isRequired } const {id} = useParams(); const [csvFiles] = useState(0); useEffect(()=>{ props.getCsvFile(id); },[]) return ( <div> <h1> File id: {id} </h1> {csvFiles} <h1> </h1> </div> ) } const mapStateToProps = state =>({ csvFiles:state.csvFile.csvFile }) export default connect(mapStateToProps,{getCsvFile,deleteCsvFile})(CsvFileDetail); When calling console.log(res) in getCsvFile, I can see that the api … -

Django smart selects doesn't work with JS cloning
I'm trying to create a page with ability to add any amount of form-copy. I use django-smart-selects to make my form's field chained. It works fine if I have only 1 form on page. Then I'm using javascript to make a function to clone form instance by pressing button and addind new form's ids to these clones. The problem is when I press "+" button I get new cloned form on page, but chained-selection doesn't work anymore, and it seems that this clone copying all my choices from the firs form and remembering this state.

ValueError: Cannot assign "1": "LeadFacilityAssign.assigned_facilities" must be a "Facility" instance
I've been trying to create an api endpoint to update my "lead" objects and add a list of facilities to them when sending a put request (each time a different amount of facilities). The lead objects already exist inside the database so do the facility objects. Since i need a date and time associated to each facility when they are being added to a lead i created the "LeadFacilityAssign" class. Since i wasn't able to get it to work i tried to do it just with a post request for now, during the lead creation process. I was told that i need to use bulk_create if i need to add more than one facility this way. I couldn't find anything on bulk_create inside the drf documentation so i decided to do this for now just with one facility and improve my code from there one issue at a time since i'm new to drf. Does anyone know what is causing this error? I tried a few different things but nothing worked so far.

Django, CORS "Access-Control-Allow-Origin" error

How to populate checkboxes in a table with values from a Django model
My html table has a column that contains a checkbox. The user can check or uncheck it. The value (boolean) is stored in the Django model Subscriber under Subscriber.participates. All objects of Subscriber are imported into the HTML using a Django view (context = {'subscribers' : Subscriber.objects.all(),}). When loading the table, the checkboxes must be set to the correct value. To that purpose I have written a javascript function, which is invoked in the <input> element. However, the checkboxes all remain unchecked, though I have verified through /admin/ in Django that some of the values in the dbase are indeed "TRUE". firstName and lastName load without any problem into the table. What did I do wrong? <head> <meta charset="UTF-8"> <title>Participants</title> <script> function checkBox() { if({{ x.participates }}){ document.getElementById("checkbox").checked = true; } else { document.getElementById("checkbox").checked = false; } } </script> </head> <body> <table> {% for x in subcribers %} <tr> <form action="updateSuscribers/{{ x.id }}" method="post"> {% csrf_token %} <td>{{ x.firstName }}</td> <td>{{ x.lastName }}</td> <td> <input id="checkbox" type="checkbox" name="participates" onload="checkBox()"> </td> </form> </tr> {% endfor %} </table> </body> -

And why do we indicate a redirection in the return when in the html we already indicate the redirection ? appIdentification/views.py from django.contrib.auth import authenticate, login, logout def logout_user(request): logout(request) messages.success(request, ("You Were Logged Out!")) return redirect('home') appIdentification/urls.py from django.urls import path from . import views urlpatterns = [ path('/login', views.login_user, name="login"), path('', views.logout_user, name="logout"), ] mainApp/template/mainApp/page1.html <body> <h1> PAGE 1 </h1> {% if user.is_authenticated %} <a href="{% url 'login' %}"> Logout </a> {% endif %} </body> mainApp/views.py @login_required def page1(request): return render(request, 'mainApp/p1.html', {}) mainApp/urls.py from django.urls import path, include from . import views path('mainApp', include('django.contrib.auth.urls')), path('mainApp', include('appIdentification.urls')), path('home', views.home, name="home"), path('p1', views.page1, name="p1"), -
Django Rest Framework: upload image to a particular existing model's object
Hey I am trying to upload an image using Rest API[via Postman] to an object which already exists, and has all its field populated except for the image. I am using PUT method, to first get the object I want to upload the image to then trying to pass it through the serializer. The images are to be uploaded to my S3 bucket. The code for my views.py: @api_view(['PUT']) @permission_classes([IsAuthenticated]) def putproof(request): app=MasterTaskHolder.objects.filter(title=request.data['title'],user=request.user) serializer=ImageUploadSerializer(app,data=request.data,partial=True) serializer.is_valid(raise_exception=True) serializer.save() return Response("Posted") My serializer: class ImageUploadSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = MasterTaskHolder fields = ( 'title','image' ) My model: class MasterTaskHolder(models.Model): status_code = [ ('C', 'Completed'), ('P', 'Pending'), ] title = models.CharField(max_length=50) point = models.IntegerField() category = models.CharField(max_length=50, null=True, blank=True) status = models.CharField(max_length=2, choices=status_code, default='P') user = models.ForeignKey(User, on_delete=models.CASCADE) image = models.ImageField(null=True, blank=True, upload_to="imageproof/") def __str__(self): return (f'{self.user} - '+(f'{self.title}')) I am really new to Django and DRF, any help would be appreciated. Thank you. -
Multiple try except in a serializer Django
I have a Warehouse model like the following: class ShelfBin(models.Model): bin_id = models.IntegerField(default=0) bin_name = models.CharField(max_length=50, default=0) class UnitShelf(models.Model): shelf_id = models.IntegerField(default=0) shelf_name = models.CharField(max_length=50, default=0) bin = models.ManyToManyField(ShelfBin, blank=True) class AisleUnit(models.Model): unit_id = models.IntegerField(default=0) unit_name = models.CharField(max_length=50, default=0) shelf = models.ManyToManyField(UnitShelf, blank=True) class ZoneAisle(models.Model): aisle_id = models.IntegerField(default=0) aisle_name = models.CharField(max_length=50, default=0) unit = models.ManyToManyField(AisleUnit, blank=True) class WarehouseZone(models.Model): zone_id = models.IntegerField(default=0) zone_name = models.CharField(max_length=50, default=0) aisle = models.ManyToManyField(ZoneAisle, blank=True) class Warehouse(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=250, default=0) address = models.CharField(max_length=500, default=0) zones = models.ManyToManyField(WarehouseZone, blank=True) for this I have created a serializer like the following: class WarehouseSerializer(serializers.ModelSerializer): zones = WarehouseZonesSerializer(many=True) class Meta: model = Warehouse fields = "__all__" def create(self, validated_data): print("validated data warehouse", validated_data) zone_objects = validated_data.pop('zones', None) instance = Warehouse.objects.create(**validated_data) for item in zone_objects: aisle_objects = item.pop('aisle') wz_obj = WarehouseZone.objects.create(**item) for data in aisle_objects: unit_objects = data.pop('unit') za_obj = ZoneAisle.objects.create(**data) for u_data in unit_objects: shelf_objects = u_data.pop('shelf') au_obj = AisleUnit.objects.create(**u_data) for s_data in shelf_objects: bin_objects = s_data.pop('bin') us_obj = UnitShelf.objects.create(**s_data) for b_data in bin_objects: b_obj = ShelfBin.objects.create(**b_data) us_obj.bin.add(b_obj) au_obj.shelf.add(us_obj) za_obj.unit.add(au_obj) wz_obj.aisle.add(za_obj) instance.zones.add(wz_obj) return instance Now the problem is that sometimes warehouse can have zone, aisle, units, etc(all 5 sub-levels) but sometimes it can only be 1,2 … -
How does multiple user types logging in & out work in a live environment? [Django]
I have a web app that has two different user types, Nurses and Doctors, and they can both log in and out. I opened two tabs and logged in as a Nurse in one tab and as a Doctor in the other. However, when I log out of either one of those tabs, the other will be automatically logged out as well. I have read this link How can made multiple user login at same time in same browser in django project and understand why this happens. I know that I can work around it by logging in from different web browsers and by using Incognito mode. However, how do I code it such that in a live environment, users can actually logout without logging other users out?
