[FIXED] TypeError: SearchProduct.get() got an unexpected keyword argument 'query'

Issue

in windows 10 , i'm using react-router-dom 5.2.0 and react-redux 7.2.5 and react 17.0.2 and axios 0.21.4 and WebStorm 2023.1.3 IDE and PyCharm Community Edition 2023.2 and djangorestframework==3.14.0 and Django==4.2.4 and djangorestframework-simplejwt==5.3.0.

question : Actually, I don't know how to send this query parameter to Django's base class view that inherits from GenericAPIView , how solve this error ?

BACKEND:

Consider - product_views.py :

class SearchProduct(GenericAPIView):

    serializer_class = ProductSerializer
    pagination_class = CustomPagination1

    def get_queryset(self, *args, **kwargs):
        # the lead id
        query = self.request.GET.get("query")

        #  this filter base on the lead id  provided
        lookup = Q(name__icontains=query) | Q(description__icontains=query) | Q(producttag__title__icontains=query)
        products = Product.objects.filter(lookup).distinct()

        return products
    def get(self, request):


        page = self.paginate_queryset(self.get_queryset())
        if page is not None:
            serializer = self.get_serializer(page, many=True)
            result = self.get_paginated_response(serializer.data)
            data = result.data  # pagination data

        else:
            serializer = self.get_serializer(queryset, many=True)
            data = serializer.data
        payload = {
            'return_code': '0000',
            'return_message': 'Success',
            'data': data
        }
        return Response(data , status=status.HTTP_200_OK)

Consider - product_urls.py:

 path('search_product/<str:query>/' , views.SearchProduct.as_view() , name="search_product"),

FRONTEND:

Consider - productAction.py:

export const productsSearchAction = (query , pageNumber) => async (dispatch , getState) => {
    try {
        dispatch({type: PRODUCTS_SEARCH_REQUEST});
        const {data} = await axios.get(`http://127.0.0.1:8000/api/v1/products/search_product/${query}/?page=${pageNumber}`);
        dispatch({type: PRODUCTS_SEARCH_SUCCESS , payload: data});
        localStorage.setItem("productsSearch" , JSON.stringify(data));
    } catch (error) {
        dispatch({ // PRODUCTS SEARCH FAILED
            type: PRODUCTS_SEARCH_FAILED,
            payload: error.response && error.response.data.detail ? error.response.data.detail : error.message,
        });
    }
}

I think the answer is simple, if you are an expert in Django and Django Rest Framework, please reply to me so that this error can be solved.

Solution

Your .get(…) method will need to accept the URL path parameters, here you can better just accept all positional and named parameters:

class SearchProduct(GenericAPIView):
    serializer_class = ProductSerializer
    pagination_class = CustomPagination1

    def get(self, request, *args, **kwargs):
        # …

Note: In Django, class-based API views (CBV) often have a …APIView suffix, to avoid a clash with the model names. Therefore you might consider renaming the view class to SearchProductAPIView, instead of SearchProduct.
