How to get and process Input for django-multiselectfield in Django rest framework via form-data
I have User model with food_prefrence field for which a user has the option to select multiple choices. In models, I am using MultiSelectField from django-multiselectfield to solve my problem. and in my User serializer, I am using fields.MultipleChoiceField provided by rest-framework. now my problem is how to get input from the user using form-data and how to process that in my view or serializer, as of now when I am trying to insert choices using postman with form-data selected, this is giving me an error when serializer.is_valid() is called { "food_preference": [ "\"'Indian', 'Continental'\" is not a valid choice." ] } below is my code snippet. #models.py class User(AbstractUser, BaseClass): food_preference = MultiSelectField(_('Food Preference'), choices=CONST_Food, blank=True, null=True) #serializer.py class UserSerializer(serializers.HyperlinkedModelSerializer): food_preference = fields.MultipleChoiceField(choices=CONST_Food, required=False) def update(self, instance, validated_data): instance.food_preference = validated_data.get('food_preference', instance.food_preference) instance.save() return instance, "Updated Successfully" #views.py def update(self, request, *args, **kwargs): instance = self.get_object() serializer = self.serializer_class(data=request.data, context={"request": self.request}) print(serializer.initial_data) if serializer.is_valid(raise_exception=True): ##<<<<<Execution stops here print("is valid") result = serializer.update(instance=instance, validated_data=request.data) if result[0] is None: return _error_response(400, EPHISH, result[1], {}) data = self.serializer_class(result[0], context={"request": self.request}).data return _response(data, status.HTTP_201_CREATED) else: return _einval_serializer_response(status.HTTP_400_BAD_REQUEST, self.serializer_class) also here is the screenshot from my postman -
Django Rest Framework Creating Foreign Key Serializer context object empty?

Is it possible to change LDAP user attributes in Django?
So I am currently trying to programm a webapplcation for ldap-user to login and change their attributes. As of now, I can authenticate ldap-accounts (using django-auth-ldap), but I do not know how to modify their attributes (i.g. first_name etc.) I could not find anything helpful for a GUI-based webapp and I am wondering what I should use and how? Which library is the right on? django-ldapdb? django-ldap3 or anything else? But most importantly, where do I programm it. Do I have to work with form (EditProfileForm), models, views... I am quite new to Python and Django, so do not mind my knowledge. If you have any idea, a link or anything helpful, do not hesitite to post it. Thanks in advance. -

Send notification on creating new object in DB
What I am using: I am using Django-REST-FrameWork & Django-Channels (WEBSocket). I have an app called "Tasks" (project/apps/tasks) and users allowed to create new Tasks via CREATE-endpoint.

Need to go one level deeper into json but am not able, upon ajax server response

Problems with nginx. How to make an authenticated call to the API using jwt (Django)?
I have some problems with nginx and django-rest-framework. I've already been trying to figure out how to make an authenticated request to the API for about 24 hours.

Django - Performance between images as fields vs images as ForeignKey model
I have a model called Listing. Users can upload up to 20 photos for each Listing.

AJAX: Having trouble retrieving queryset from server and appending to select options
I am able to send the value of the input field with the id datepicker to the server. And with this in the view I filter the time slot by the ones that occur on the same date. Where I am having difficulties is sending this queryset to the browser and then appending this to the options. I'm still relatively new to javascript I apologize if this is a newb question. I definitely appreciate any feedback! My View: if request.is_ajax(): selected_date = request.POST['selected_date'] slots_on_day = Calendar.objects.filter(date=selected_date) return HttpResponse(slots_on_day) My Javascript: $(document).ready(function() { $("#datepicker").change(function(){ document.getElementById("display_slots").style.display ="block"; $.ajax({ type: 'POST', data: { 'selected_date':$('#datepicker').val(), 'csrfmiddlewaretoken' : $("input[name=csrfmiddlewaretoken]").val() }, success: function(resp){ console.log('slots_on_day') for (var i=0; i < resp['slots_on_day'].length;++i){ addOption( document.getElementById("display_slots"), resp['slots_on_day'][i], resp['slots_on_day'][i]); } } }); }); }); Notes: the id=datepicker field triggers the ajax event.

Django static files not loading. Fix settings.py to load files on relative paths
I downloaded this template https://github.com/BlackrockDigital/startbootstrap-resume and I am trying to use it in Django. I am having problems with static files, that is .css and .jpg. My project is called Djangoresume and the app is resume. I copied the template files to my /home/kinkyboy/Djangoresume/resume/templates/resume (if you think the last resume folder is not the common way to do organize the project, please let me know): > pwd /home/kinkyboy/Djangoresume/resume/templates/resume > tree -L1 . ├── css ├── gulpfile.js ├── img ├── js ├── index.html ├── scss ├── static │ ├── css │ ├── img │ ├── js │ ├── scss │ └── vendor └── vendor Notice that I added the same static files to a new folder "static" to increase my chances of making Django work, but I'd rather not use it.

STATIC_URL = 'static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, '/resume/templates/resume/static') ] But I tried many different folders. I see that {% static %} uses STATIC_URL, and probably staticfiles will use STATICFILES_DIRS. BASE_DIR is where manage.py is, right?

How to sort the results of filtering with django-filter in a ListAPIView
I have a ListAPIView that uses the DjangoFilterBackend to filter rooms based on url parameters. The code below does this just fine. Now, I would like to sort the results based on a score calculated from other attributes of the Room object, another url parameter, and possibly what we know about the user issuing the request. The function itself does not matter. How can I sort the results after applying the filter I already have? If I were to do the filtering myself, I suppose I could do the filtering, calculate the score and sort the results in the get_queryset but I do not know how to do this after the filtering with django-filter. Example query For example, I would do this query to filter by price lower than 100. The other_field value would be used to compute the score for sorting: http://localhost:8000/api/search/rooms?price=100&other_field=200 Code class RoomFilter(filters.FilterSet): price = filters.NumberFilter(name="price", lookup_expr='lte') features = filters.ModelMultipleChoiceFilter( name="features", conjoined=True, queryset=Features.objects.all() ) class Meta: model = Room fields = ['price', 'features'] class RoomSearchView(generics.ListAPIView): queryset = Room.objects.all() serializer_class = RoomSearchSerializer filter_backends = (filters.DjangoFilterBackend,) filter_class = RoomFilter -
Django doesn't recognize DEBUG = False
I'm trying to develop 404 and 500 error custom templates for my Django project. When I change DEBUT to False, Django always returns me: You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. What am I doing wrong? Why Django does not recognize the variable?
