I'm lost on how to create a functioning search bar django/react-CodePudding

On my ecommerce project I wanna impelement a search bar where you can search products by name through drf api, I installed django_filters and created a class like so:

class ProductFilter(generics.ListCreateAPIView):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer
    filter_backends = [filters.SearchFilter]
    search_fields = ['^name']

I tested the endpoint and it works but I don't know how to make it work on the frontend part with react, I have the saerchbar in the header like so:

<Form className="d-flex">
 <Form.Control
   type="search"
   placeholder="Search"
   className="me-2"
   aria-label="Search"
 />
 <Button variant="outline-success">Search</Button>
</Form>

Using axios for api calls, I have no idea how to set this up and if I need reducers, actions, store too

CodePudding user response：

I think you can create a function which will make an api call when user enters any text in the input. Also, debounce it to avoid frequent api calls.

import React, { useCallback } from "react";

// Debounce to avoid frequent api calls
export const debounce = (func, waitFor) => {
  let timeout = null;

  const debounced = (...args) => {
    if (timeout !== null) {
      clearTimeout(timeout);
      timeout = null;
    }
    timeout = setTimeout(() => func(...args), waitFor);
  };

  return debounced;
};

const TestComponent = () => {
  // debounce the function so that we send api calls once user stops typing
  const searchSomething = useCallback(
    debounce(async (value) => {
      try {
        // Make your api call using whichever library you are using
        // let response = await fetch(`${YOUR_SERVER_URL}/search?query=${value}`);
        let response =  axios.get(`${YOUR_SERVER_URL}/search?query=${value}`)
        console.log(response);
      } catch (error) {
        console.log(error);
      }
    }, 500),
    []
  );

  return (
    <Form className="d-flex">
      <Form.Control
        type="search"
        placeholder="Search"
        className="me-2"
        aria-label="Search"
        onChange={(e) => {
          searchSomething(e.target.value);
        }}
      />
      <Button variant="outline-success">Search</Button>
    </Form>
  );
};

export default TestComponent;

CodePudding user response：

Your axios call should end up something like this:

axios({
  method: 'post',
  url: '/login', // replace with your endpoint URL
  data: {
    searchField.name: searchField.value,
  }
});

with searchField.name being whatever field name Django is expecting to receive on the back end (it looks like it's name here), and searchField.value being the value of the search field.
