Hi @fixmycss. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To pass custom parameters like fromdate in the URL using a custom data provider in refine, you can use the useCustom hook. This hook allows you to specify the endpoint URL and query parameters. Here's an example of how you can achieve this:

import { useCustom } from "@refinedev/core";

useCustom({
  url: "www.example.com/api/get-products",
  method: "get",
  config: {
    query: {
      fromdate: "2023-01-01",
      todate: "2023-12-31",
    },
  },
});

import { useCustom } from "@refinedev/core";

useCustom({
  url: "www.example.com/api/get-products",
  method: "get",
  config: {
    query: {
      fromdate: "2023-01-01",
      todate: "2023-12-31",
    },
  },
});

In this example: - The url property specifies the endpoint of the request. - The method property specifies the HTTP method of the request (in this case, get). - The config.query property is used to pass custom query parameters like fromdate and todate. For more detailed information, you can refer to the useCustom documentation (https://refine.dev/docs/data/hooks/use-custom/#configquery). If you need to pass custom headers as well, you can include them in the config property:

import { useCustom } from "@refinedev/core";

useCustom({
  url: "www.example.com/api/get-products",
  method: "get",
  config: {
    query: {
      fromdate: "2023-01-01",
      todate: "2023-12-31",
    },
    headers: {
      "X-Custom-Header": "Custom header value",
    },
  },
});

import { useCustom } from "@refinedev/core";

useCustom({
  url: "www.example.com/api/get-products",
  method: "get",
  config: {
    query: {
      fromdate: "2023-01-01",
      todate: "2023-12-31",
    },
    headers: {
      "X-Custom-Header": "Custom header value",
    },
  },
});

This way, you can pass both custom query parameters and headers to your custom data provider. For more information on passing custom headers, you can refer to the Passing custom headers documentation (https://refine.dev/docs/data/packages/simple-rest/#passing-custom-headers). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

i need to access param value from a usecontext thst i have created @kapa.ai i need to access param value from a usecontext thst i have created

Let me check the knowledge base for you. One moment! :books: ---------------------- To access a parameter value from a useContext that you have created, you need to follow these steps: 1. Create the Context and Provider: First, create a context and a provider component that will supply the context value. 2. Consume the Context: Use the useContext hook to access the context value in your component. Here's an example to illustrate this: Step 1: Create the Context and Provider

import React, { createContext, useContext, useState } from "react";

// Create the context
const ParamContext = createContext();

// Create the provider component
export const ParamProvider = ({ children }) => {
  const [params, setParams] = useState({ fromdate: "2023-01-01", todate: "2023-12-31" });

  return (
    <ParamContext.Provider value={{ params, setParams }}>
      {children}
    </ParamContext.Provider>
  );
};

import React, { createContext, useContext, useState } from "react";

// Create the context
const ParamContext = createContext();

// Create the provider component
export const ParamProvider = ({ children }) => {
  const [params, setParams] = useState({ fromdate: "2023-01-01", todate: "2023-12-31" });

  return (
    <ParamContext.Provider value={{ params, setParams }}>
      {children}
    </ParamContext.Provider>
  );
};

Step 2: Consume the Context

import React from "react";
import { useContext } from "react";
import { ParamContext } from "./ParamContext"; // Adjust the import path as necessary

const MyComponent = () => {
  const { params } = useContext(ParamContext);

  return (
    <div>
      <p>From Date: {params.fromdate}</p>
      <p>To Date: {params.todate}</p>
    </div>
  );
};

import React from "react";
import { useContext } from "react";
import { ParamContext } from "./ParamContext"; // Adjust the import path as necessary

const MyComponent = () => {
  const { params } = useContext(ParamContext);

  return (
    <div>
      <p>From Date: {params.fromdate}</p>
      <p>To Date: {params.todate}</p>
    </div>
  );
};

Step 3: Use the Provider in Your Application Wrap your application or the part of your application that needs access to the context with the ParamProvider.

import React from "react";
import { ParamProvider } from "./ParamContext"; // Adjust the import path as necessary
import MyComponent from "./MyComponent"; // Adjust the import path as necessary

const App = () => {
  return (
    <ParamProvider>
      <MyComponent />
    </ParamProvider>
  );
};

export default App;

import React from "react";
import { ParamProvider } from "./ParamContext"; // Adjust the import path as necessary
import MyComponent from "./MyComponent"; // Adjust the import path as necessary

const App = () => {
  return (
    <ParamProvider>
      <MyComponent />
    </ParamProvider>
  );
};

export default App;

In this example: - The ParamProvider component provides the context value (params) to its children. - The MyComponent component consumes the context value using the useContext hook. This setup allows you to access and use the params value from the context in any component that is a descendant of the ParamProvider. For more detailed information on how to use the React Context API, you can refer to the guide on consuming context in React (https://refine.dev/blog/usecontext-and-react-context/#how-to-consume-context-in-react). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i am seem to having issue in concuming my context inside getList inside dataprovider

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To consume your context inside the getList method of your custom data provider, you need to ensure that the context is accessible within the scope where getList is defined. This can be a bit tricky because getList is typically defined outside of the React component tree where the context provider is used. One approach to solve this is to pass the context value as a parameter to the getList method. Here’s how you can achieve this: Step 1: Create the Context and Provider

import React, { createContext, useContext, useState } from "react";

// Create the context
const ParamContext = createContext();

// Create the provider component
export const ParamProvider = ({ children }) => {
  const [params, setParams] = useState({ fromdate: "2023-01-01", todate: "2023-12-31" });

  return (
    <ParamContext.Provider value={{ params, setParams }}>
      {children}
    </ParamContext.Provider>
  );
};

import React, { createContext, useContext, useState } from "react";

// Create the context
const ParamContext = createContext();

// Create the provider component
export const ParamProvider = ({ children }) => {
  const [params, setParams] = useState({ fromdate: "2023-01-01", todate: "2023-12-31" });

  return (
    <ParamContext.Provider value={{ params, setParams }}>
      {children}
    </ParamContext.Provider>
  );
};

Step 2: Define the Data Provider Modify your data provider to accept context values as parameters:

import { DataProvider } from "@refinedev/core";

const dataProvider: DataProvider = {
  getList: async ({ resource, pagination, sorters, filters, meta }, contextParams) => {
    const { fromdate, todate } = contextParams;

    // Use the context parameters in your API call
    const response = await fetch(`<https://api.example.com/${resource}?fromdate=${fromdate}&todate=${todate}`>);
    const data = await response.json();

    return {
      data: data.items,
      total: data.total,
    };
  },
  // Other methods...
};

export default dataProvider;

import { DataProvider } from "@refinedev/core";

const dataProvider: DataProvider = {
  getList: async ({ resource, pagination, sorters, filters, meta }, contextParams) => {
    const { fromdate, todate } = contextParams;

    // Use the context parameters in your API call
    const response = await fetch(`<https://api.example.com/${resource}?fromdate=${fromdate}&todate=${todate}`>);
    const data = await response.json();

    return {
      data: data.items,
      total: data.total,
    };
  },
  // Other methods...
};

export default dataProvider;

Step 3: Consume the Context and Pass it to the Data Provider In your component, consume the context and pass it to the data provider:

import React, { useContext } from "react";
import { useList } from "@refinedev/core";
import { ParamContext } from "./ParamContext"; // Adjust the import path as necessary

const MyComponent = () => {
  const { params } = useContext(ParamContext);

  const { data, isLoading } = useList({
    resource: "products",
    config: {
      contextParams: params, // Pass the context parameters here
    },
  });

  if (isLoading) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      {data.map((item) => (
        <div key={item.id}>{item.name}</div>
      ))}
    </div>
  );
};

export default MyComponent;

import React, { useContext } from "react";
import { useList } from "@refinedev/core";
import { ParamContext } from "./ParamContext"; // Adjust the import path as necessary

const MyComponent = () => {
  const { params } = useContext(ParamContext);

  const { data, isLoading } = useList({
    resource: "products",
    config: {
      contextParams: params, // Pass the context parameters here
    },
  });

  if (isLoading) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      {data.map((item) => (
        <div key={item.id}>{item.name}</div>
      ))}
    </div>
  );
};

export default MyComponent;

Step 4: Use the Provider in Your Application Wrap your application or the part of your application that needs access to the context with the ParamProvider.

import React from "react";
import { ParamProvider } from "./ParamContext"; // Adjust the import path as necessary
import MyComponent from "./MyComponent"; // Adjust the import path as necessary

const App = () => {
  return (
    <ParamProvider>
      <MyComponent />
    </ParamProvider>
  );
};

export default App;

import React from "react";
import { ParamProvider } from "./ParamContext"; // Adjust the import path as necessary
import MyComponent from "./MyComponent"; // Adjust the import path as necessary

const App = () => {
  return (
    <ParamProvider>
      <MyComponent />
    </ParamProvider>
  );
};

export default App;

In this setup: - The ParamProvider component provides the context value (params) to its children. - The MyComponent component consumes the context value using the useContext hook and passes it to the useList hook. - The getList method in the data provider uses the context parameters to make the API call. This approach ensures that the context value is accessible within the getList method of your ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
