permission based on the action/url in Django rest framewrok
I have a Modelviewset class that has several functions inside it like list(), destroy, partial_update() and also other custom functions like def get_examples(self,request). The thing is different functions have different permissions based on the user types. I have a separate permission class inside a permission file. Now I need to access the action inside the has_permission function. I know it can be done inside the get_permission function inside modelviewset class. But how can we do it inside has_permission function?? My View: class ExampleView(viewsets.ModelViewSet): queryset = Example.objects.all().order_by("-created_at") serializer_class = ExampleSerializer pagination_class = ExampleNumberPagination def list(self, request, *args, **kwargs): def partial_update(self, request, *args, **kwargs): def custom_fuctin_1(self,request,*args,**kwargs): def custom_fuctin_2(self,request,*args,**kwargs): def destroy(self, request, *args, **kwargs): Now permission file: class ExampleClassPermission(BasePermission): def has_permission(self, request, view): user =request.user if request.method == 'GET' or request.method == 'POST': return True elif request.method == 'DELETE' and (user.role == 'manager' or user.role == 'admin'): return True elif request.method == 'PUT': return True else: return False Here in this permission class, I want to set permission for custom function_1 and 2 in the view class. I cant do self.action == ''? just like in the get_permission.Can I?? -

'manager_method() argument after ** must be a mapping, not str' when overloading nested ModelSerialiver.create(...)
I want to overload a ModelSerializer create() method in a generic way using Django RestFramework inspection functions. for the purpose of testing the concept on a related_name of a ForeingKey i have the following models and corresponding serializer. models.py class Country(models.Model): pass class People(models.Model): country = models.ForeignKey( to="myapp.Country", null=True, blank=True, on_delete=models.SET_NULL, related_name="country_people" ) serializer.py class CountrySerializer(serializers.ModelSerializer): country_people = PeopleSerializer(many=True) def create(self, validated_data): country_people_data = validated_data.pop("country_people", []) instance = super().create(validated_data) for cp_data in country_people_data: cp_data["country"] = instance self.get_fields()["country_people"].create(cp_data) class Meta: fields= "__all__" model = Country example of data # json data for country serializer { ..., "country_people":[ {...}, {...} ] } When calling CountrySerializer.save() the CountrySerializer.create() will be called and it will save also nested data on People table. The issue is that I got the following error ModelClass._default_manager.create(**validated_data) TypeError: django.db.models.manager.BaseManager._get_queryset_methods.<locals>.create_method.<locals>.manager_method() argument after ** must be a mapping, not str using People.create(**cp_data) is working but it is not the solution in my context I want to solve it using self.get_fields because I want it to be generic and because PeopleSerializer could nest another serializer so back and so forth -
I want to show the total rows beside the search and make search code work in python?
I created a table and I want to do a search for two columns (id and name) so when the user enters any letter or number of name, id columns it shows all row names containing that letter and I want to show the total rows of my table next to search box. in HTML <table class="table table-striped " id="table1"> <tbody> {% for i in data_list %} <tr> <td>{{ forloop.counter }}</td> <td>{{i.employee_code}}</td> <td>{{i.employee_name}}</td> <td>{{i.email}}</td> </tr> {% endfor %} </tbody> </table> In JS I did the search code but it does not work! function searchrecords() { var input,table,tr,td,filter; input=document.getElementById("searchtext"); filter=input.value.toUpperCase(); table=document.getElementById("table1"); tr=table.getElementsByTagName("tr"); for(i=0;i<tr.length;i++) { td=tr[i].getElementsByTagName("td")[0]; if(td) { textdata=td.innerText; if(textdata.toUpperCase().indexOf(filter)>-1) { tr[i].style.display=""; } else { tr[i].style.display="none"; } } } } -
