Adding variables to query

Wanted to know if it is possible to add variables to such a query: const { data: responseData, isLoading: locationLoading } = useList<ObdHistoryQuery>({ resource: "obd_datas", meta: { gqlQuery: OBD_GET_HISTORY, }, queryOptions: { enabled: true, }, });

Hi @Valugar. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, it is possible to add variables to your GraphQL query in the useList hook by using the meta property. You can pass the variables through the meta.gqlVariables field. Here is an example based on the information from the knowledge sources:

const { data: responseData, isLoading: locationLoading } = useList<ObdHistoryQuery>({
  resource: "obd_datas",
  meta: {
    gqlQuery: OBD_GET_HISTORY,
    gqlVariables: {
      where: {
        _and: [
          {
            title: {
              _ilike: "%test%",
            },
          },
        ],
      },
    },
  },
  queryOptions: {
    enabled: true,
  },
});

const { data: responseData, isLoading: locationLoading } = useList<ObdHistoryQuery>({
  resource: "obd_datas",
  meta: {
    gqlQuery: OBD_GET_HISTORY,
    gqlVariables: {
      where: {
        _and: [
          {
            title: {
              _ilike: "%test%",
            },
          },
        ],
      },
    },
  },
  queryOptions: {
    enabled: true,
  },
});

In this example, the gqlVariables field is used to pass the variables to the GraphQL query. This allows you to add any conditions supported by your GraphQL server, such as filtering data based on specific criteria. For more details, you can refer to the GitHub issue discussing this feature (https://github.com/refinedev/refine/issues/5864). If you need further customization or have more specific requirements, you might want to check the useQuery documentation (https://tanstack.com/query/v4/docs/react/reference/useQuery) for additional options you can pass through queryOptions. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Not sure how to do it. Specifically I have this: export const OBD_GET_HISTORY = gql


    query OBDHistory($v_id: String) {
        historicalObdData(vId: $v_id) {
            driver 
            {
                id
                name
            }
            timestamp
            rpm
            speed
            coolantTemp
            throttlePosition
            intakeAirTemp
            fuelLevel
            engineLoad
            mafSensor
            runTime
            distanceMilOn
            commandedEgr
            barometricPressure        
        }
    }

; and I want to add the vid string to it.

Let me check the knowledge base for you. One moment! :books: ---------------------- To add the v_id variable to your GraphQL query using the useList hook, you can pass the variable through the meta.gqlVariables field. Here is how you can do it: First, ensure your GraphQL query is defined as follows:

export const OBD_GET_HISTORY = gql`
    query OBDHistory($v_id: String) {
        historicalObdData(vId: $v_id) {
            driver {
                id
                name
            }
            timestamp
            rpm
            speed
            coolantTemp
            throttlePosition
            intakeAirTemp
            fuelLevel
            engineLoad
            mafSensor
            runTime
            distanceMilOn
            commandedEgr
            barometricPressure        
        }
    }
`;

export const OBD_GET_HISTORY = gql`
    query OBDHistory($v_id: String) {
        historicalObdData(vId: $v_id) {
            driver {
                id
                name
            }
            timestamp
            rpm
            speed
            coolantTemp
            throttlePosition
            intakeAirTemp
            fuelLevel
            engineLoad
            mafSensor
            runTime
            distanceMilOn
            commandedEgr
            barometricPressure        
        }
    }
`;

Then, use the useList hook and pass the v_id variable through the meta.gqlVariables field:

const { data: responseData, isLoading: locationLoading } = useList({
  resource: "obd_datas",
  meta: {
    gqlQuery: OBD_GET_HISTORY,
    gqlVariables: {
      v_id: "your_vid_value", // Replace "your_vid_value" with the actual v_id value
    },
  },
  queryOptions: {
    enabled: true,
  },
});

const { data: responseData, isLoading: locationLoading } = useList({
  resource: "obd_datas",
  meta: {
    gqlQuery: OBD_GET_HISTORY,
    gqlVariables: {
      v_id: "your_vid_value", // Replace "your_vid_value" with the actual v_id value
    },
  },
  queryOptions: {
    enabled: true,
  },
});

In this example, replace "your_vid_value" with the actual value of v_id that you want to use in your query. For more details, you can refer to the GitHub issue discussing this feature (https://github.com/refinedev/refine/issues/5864). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai It's not working. Is it possible there is a different way? I see that the call is constantly has these variables: { "filter": {}, "sorting": [], "paging": { "limit": 10, "offset": 0 } }

kapa.ai•4w ago

Let me check the knowledge base for you. One moment! :books: ---------------------- It looks like you are encountering an issue where the useList hook is not correctly passing the variables to your GraphQL query. Based on the knowledge sources, you can pass additional parameters like filters, sorters, and pagination to the useList hook, which are then handled by the data provider. Here is an example of how you can modify your useList hook to include the v_id variable using the filters parameter:

const { data: responseData, isLoading: locationLoading } = useList({
  resource: "obd_datas",
  filters: [
    {
      field: "v_id",
      operator: "eq",
      value: "your_vid_value", // Replace "your_vid_value" with the actual v_id value
    },
  ],
  meta: {
    gqlQuery: OBD_GET_HISTORY,
  },
  queryOptions: {
    enabled: true,
  },
});

const { data: responseData, isLoading: locationLoading } = useList({
  resource: "obd_datas",
  filters: [
    {
      field: "v_id",
      operator: "eq",
      value: "your_vid_value", // Replace "your_vid_value" with the actual v_id value
    },
  ],
  meta: {
    gqlQuery: OBD_GET_HISTORY,
  },
  queryOptions: {
    enabled: true,
  },
});

In this example, the filters parameter is used to pass the v_id variable to the query. The data provider should handle this filter and include it in the GraphQL request. For more details on how to use filters, sorters, and pagination with the useList hook, you can refer to the documentation on data fetching (https://refine.dev/docs/guides-concepts/data-fetching/#multiple-data-providers). If this approach still does not work, you might need to check if your data provider correctly handles the filters parameter and translates it into the appropriate GraphQL variables. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Ok I want help with understanding how sending and receiving the proper data. I have this: const { data: responseData, isLoading: locationLoading } = useList<ObdHistoryQuery>({ filters: [ { field: "vehicle", value: vehicleId, operator: "eq", } ], meta: { gqlQuery: OBD_GET_HISTORY, }, queryOptions: { enabled: true, }, }); And this query: export const OBD_GET_HISTORY = gql


    query OBDHistory(
        $filter: OBDDataFilter!
        $sorting: [OBDDataSort!]!
        $paging: OffsetPaging!
    ) {
        historicalObdData(filter: $filter, sorting: $sorting, paging: $paging) {
            driver 
            {
                id
                name
            }
            timestamp
            rpm
            speed
            coolantTemp
            throttlePosition
            intakeAirTemp
            fuelLevel
            engineLoad
            mafSensor
            runTime
            distanceMilOn
            commandedEgr
            barometricPressure        
        }
    }

; And this is the response I see: { "data": { "historicalObdData": [ { "driver": { "id": "2", "name": "Leroy" }, "timestamp": "2024-09-07 21:15:28.317170+00:00", "rpm": 6095, "speed": 76, "coolantTemp": 4.0, "throttlePosition": 68.23529411764706, "intakeAirTemp": 149.0, "fuelLevel": 9.411764705882353, But on the frontend Refine, I cant access the data. Why is this? What should the data structure be?

kapa.ai•4w ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To ensure that you can access the data correctly on the frontend using Refine's useList hook, you need to make sure that the data structure returned by your GraphQL query matches what Refine expects. Based on the provided query and response, it looks like the data is being returned correctly from the backend. However, you might be facing issues with how the data is being accessed or mapped on the frontend. Here is a step-by-step guide to ensure you are handling the data correctly: 1. Ensure the Query Structure Matches the Expected Format: Your GraphQL query should be structured to match the expected format by Refine. The useList hook expects the data to be in a specific format, typically an array of objects. 2. Check the Data Mapping on the Frontend: Make sure you are correctly mapping the data returned by the useList hook. Here is an example of how you can access and display the data:

import { useList } from "@refinedev/core";
import { OBD_GET_HISTORY } from "./queries"; // Adjust the import path as necessary

const VehicleDataList: React.FC = () => {
  const { data: responseData, isLoading, isError } = useList({
    resource: "obd_datas",
    filters: [
      {
        field: "vehicle",
        value: "your_vehicle_id", // Replace with the actual vehicle ID
        operator: "eq",
      },
    ],
    meta: {
      gqlQuery: OBD_GET_HISTORY,
    },
    queryOptions: {
      enabled: true,
    },
  });

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

  if (isError) {
    return <div>Something went wrong!</div>;
  }

  const historicalObdData = responseData?.data?.historicalObdData ?? [];
return (
    <ul>
      {historicalObdData.map((data, index) => (

@kapa.ai So I changed the query and now I have: export const OBD_GET_HISTORY = gql


    query OBDHistory(
        $filter: OBDDataFilter!
        $sorting: [OBDDataSort!]!
        $paging: OffsetPaging!
    ) {
        historicalObdData(filter: $filter, sorting: $sorting, paging: $paging) {
            totalCount
            nodes {
                driver 
                {
                    id
                    name
                }
                timestamp
                rpm
                speed
                coolantTemp
                throttlePosition
                intakeAirTemp
                fuelLevel
                engineLoad
                mafSensor
                runTime
                distanceMilOn
                commandedEgr
                barometricPressure        
            }
        }
    }

; And I set this: const { data: responseData, isLoading: locationLoading } = useList<ObdHistoryQuery>({ meta: { gqlQuery: OBD_GET_HISTORY, }, queryOptions: { enabled: true, }, }); and when analyzing the network I see the response is proper as: { "data": { "historicalObdData": { "totalCount": 237, "nodes": [ { "driver": { "id": "2", "name": "Leroy" }, "timestamp": "2024-09-07 21:15:28.317170+00:00", "rpm": 6095, "speed": 76, "coolantTemp": 4.0, "throttlePosition": 68.23529411764706, "intakeAirTemp": 149.0, ... But when I try to console.log(responseData) I keep getting undefined!

Let me check the knowledge base for you. One moment! :books: ---------------------- It looks like your GraphQL query and the response structure are correct, but you are still getting undefined when trying to access responseData. This issue might be due to how the data is being accessed or mapped in your component. Here is a step-by-step guide to ensure you are handling the data correctly: 1.

3. Verify the Data Structure: Ensure that the data structure returned by your GraphQL query matches what you are trying to access on the frontend. The useList hook expects the data to be in a specific format, typically an array of objects under the data property. By following these steps, you should be able to correctly access and display the data returned by your GraphQL query. If you continue to face issues, double-check the structure of the response and ensure that the data provider is correctly configured to handle GraphQL queries. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Ok why am I getting this error: TypeError: Cannot read properties of undefined (reading 'nodes') at getList If this is the query: export const OBD_GET_HISTORY = gql


    query OBDHistory(
        $filter: OBDDataFilter!
        $sorting: [OBDDataSort!]!
        $paging: OffsetPaging!) {
        historicalObdData(filter: $filter, sorting: $sorting, paging: $paging) {
            totalCount
            nodes {
                id
                driver 
                {
                    id
                    name
                }
                timestamp
                rpm
                speed
                coolantTemp
                throttlePosition
                intakeAirTemp
                fuelLevel
                engineLoad
                mafSensor
                runTime
                distanceMilOn
                commandedEgr
                barometricPressure        
            }
        }
    }

; And this is the refine code: const { data: responseData, isLoading: locationLoading, failureReason: failureReason } = useList<GetFieldsFromList<ObdHistoryQuery>>({ resource: "obd_data", filters: [ { field: "vehicle", value: vehicleId, operator: "eq", } ], meta: { gqlQuery: OBD_GET_HISTORY, }, queryOptions: { enabled: true, }, }); And on the network this is the response: { "data": { "historicalObdData": { "totalCount": 149, "nodes": [ { "id": "68", "driver": { "id": "2", "name": "Leroy" }, "timestamp": "2024-09-07 21:15:28.317170+00:00", "rpm": 6095, "speed": 76, "coolantTemp": 4.0, "throttlePosition": 68.23529411764706, ...

Let me check the knowledge base for you. One moment! :books: ---------------------- The error TypeError: Cannot read properties of undefined (reading 'nodes') at getList suggests that the nodes property is not being accessed correctly in the getList function. This could be due to how the data is being mapped or accessed in your frontend code. Here is a step-by-step guide to ensure you are handling the data correctly: 1. Ensure the Query Structure Matches the Expected Format: Your GraphQL query looks correct and should return the data in the expected format. 2. Check the Data Mapping on the Frontend: Make sure you are correctly mapping the data returned by the useList hook. Here is an example of how you can access and display the data:

import { useList } from "@refinedev/core";
import { OBD_GET_HISTORY } from "./queries"; // Adjust the import path as necessary

const VehicleDataList: React.FC = () => {
  const { data: responseData, isLoading, isError, failureReason } = useList({
    resource: "obd_data",
    filters: [
      {
        field: "vehicle",
        value: "your_vehicle_id", // Replace with the actual vehicle ID
        operator: "eq",
      },
    ],
    meta: {
      gqlQuery: OBD_GET_HISTORY,
    },
    queryOptions: {
      enabled: true,
    },
  });

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

  if (isError) {
    console.error(failureReason);
    return <div>Something went wrong!</div>;
  }

  // Access the data correctly
  const historicalObdData = responseData?.data?.historicalObdData?.nodes ?? [];
return (
    <ul>
      {historicalObdData.map((data, index) => (
        <li key={index}>
          <h4>Driver: {data.driver.name}</h4>
          <p>Timestamp: {data.timestamp}</p>
          <p>RPM: {data.rpm}</p>
          <p>Speed: {data.speed}</p>

          <p>Barometric Pressure: {data.barometricPressure}</p>
        </li>
      ))}
    </ul>
  );
};

export default VehicleDataList;

    ],
    meta: {
      gqlQuery: OBD_GET_HISTORY,

    queryOptions: {
      enabled: true,

  });
