you'll just create an endpoint that receives a query parameter with the string to search for, and you'll search using YOURMODEL.objects.get(field=query_params.get("search_str"))

the frontend will be responsible for making the requests to search while typing

so, in your views.py you'll do something like this:

from rest_framework.views import APIView
from rest_framework.response import Response


from .models import YourModel


class Search(APIView):
    def get(self, request):
        search_str = request.query_params.get("search_str")
        results = YourModel.objects.get(field_to_search=search_str)
        return Response({"results": results})

you'll tie it to a route in urls.py file

and you're good to go

Hi Ahmed,

Here is my code:

Views.py

class DatasetListAPIView(ListAPIView):
    serializer_class = DatasetlSerializer
    def get_queryset(self):
        qs = Dataset.objects.all()
        word = self.request.query_params.get('word')
        if word is not None:
            qs  = qs.filter(name__icontains = word).order_by(Length('name').asc(),'-hits')
        return qs
    search_fields = ('name',)

but if my end user type something like:

http://127.0.0.1:8000/search/?word = a

then I want to show some database match record suggestion like:

http://127.0.0.1:8000/search/?word = an

http://127.0.0.1:8000/search/?word = at

http://127.0.0.1:8000/search/?word = ant

I think I need to override inbuilt HTML and Javascript,But I don't know How to do that Please tell me How I can do that. 

Thank You for your response

Soumen

Hi Folks,

 I have three models like Company,Employee and images. Images is foreignkey in my Company table. At the time of creating Company deatils I want to add image also, How I add these image in my image tables and at the time to get method how i can show company details along with image using django rest framework.

models.py

class Image(models.Model):
    company_image =  models.ImageField(upload_to='company_image',default = 'default.jpg')
    created_at = models.DateField(auto_now_add = True)
    updated_at = models.DateField(auto_now = True)
    class Meta:
        verbose_name = 'image'

    def  __str__(self):
        return self.company_image

class Company(models.Model):
    cmp_image = models.ForeignKey(Image,related_name = 'comp_image',on_delete =                                                                                    models.CASCADE)
    name = models.CharField(max_length = 100)
    reg_no = models.IntegerField()
    ceo = models.CharField(max_length = 100)
    location = models.CharField(max_length = 100)
    active = models.BooleanField(default=True)
    created_at = models.DateField(auto_now_add = True)
    updated_at = models.DateField(auto_now = True)

    def __str__(self):
        return self.name

Hi,

This is possible if you have a nested serializer that allow creation. We have created a plugin for that :

https://pypi.org/project/drf-nested/

There are several others out there that do this also - so it's completely possible.

However when looking at your code  - I think the relationship isn't correct? The way you have written your code - the image is the main object and the company is secondary to it. So when you delete the image, the company will also be deleted - and you can add several companies to the same image, and not the other way around. If that is the way you want it then it's fine. But I would have a foreign key in the image to the company.

Andréas

All of the code is documented and there should be some readme to help you get started.
