how to set a filter to a table based on a value that is from another table

I am developing an application using refine and supabase. I have a table called OrderProduct which is an intermediate table between two 3 tables. Client, Product and Order. The issue is that I have to make a filter based on a value of the table Order. which is the Status, and I can not do it correctly. Currently I get an error that order_product.status does not exist (Duh). But I can't figure out how to do this. this is the IOrderProduct id: number; order_id: number; product_id: number; quantity: number;

Hi @ElDogger. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In refine, you can use the useTable hook to apply filters to your table data. The useTable hook has a filter feature that allows you to set initial and permanent filter states. These states are a CrudFilter type that contains the field, the operator, and the value of the filter. You can change the filters state by using the setFilters function. Every change will trigger a new fetch. Here is an example of how you might use the useTable hook to filter your data:

const filter = statusFilter
    ? [
        {
          field: "status",
          operator: "eq",
          value: statusFilter,
        },
      ]
    : [];
  const { tableProps: orderTableProps } = useTable({
    syncWithLocation: true,
    resource: "order_product",
    filters: {
      initial: filter,
      permanent: [
        {
          field: "order_id",
          operator: "eq",
          value: id,
        },
      ],
    },
  });

const filter = statusFilter
    ? [
        {
          field: "status",
          operator: "eq",
          value: statusFilter,
        },
      ]
    : [];
  const { tableProps: orderTableProps } = useTable({
    syncWithLocation: true,
    resource: "order_product",
    filters: {
      initial: filter,
      permanent: [
        {
          field: "order_id",
          operator: "eq",
          value: id,
        },
      ],
    },
  });

In this example, statusFilter is the value you want to filter by. The field is set to "status", the operator is set to "eq" (equals), and the value is set to statusFilter. This will filter your table data to only include rows where the status equals the statusFilter value. However, based on your description, it seems like the status field is not in the OrderProduct table but in the Order table. In this case, you might need to adjust your data model or your API to allow filtering OrderProduct by the Order status. This might involve joining the Order and OrderProduct tables in your API or adding a status field to the OrderProduct table. For more information, you can check the refine documentation on useTable (https://refine.dev/docs/data/hooks/use-table#filtering) and refine documentation on tables (https://refine.dev/docs/guides-concepts/tables#filtering-). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can i filter the order.status if in the OrderProduct i have the order_id

kapa.ai•9mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To filter the order.status in the OrderProduct table where you only have the order_id, you would need to adjust your API to support this kind of filtering. In your API, when you receive a request to get the OrderProduct data with a filter on the order.status, you would need to join the Order and OrderProduct tables based on the order_id, and then apply the filter on the order.status. Unfortunately, the specifics of how to do this would depend on the specifics of your API and your database. You might need to write a custom SQL query, or use the features of your ORM if you're using one. Once your API supports this kind of filtering, you can use the useTable hook in refine to send the filter to the API. Here's an example:

const { tableProps } = useTable({
  resource: "order_product",
  filters: {
    initial: [
      {
        field: "order.status",
        operator: "eq",
        value: "desired_status",
      },
    ],
  },
});

const { tableProps } = useTable({
  resource: "order_product",
  filters: {
    initial: [
      {
        field: "order.status",
        operator: "eq",
        value: "desired_status",
      },
    ],
  },
});

In this example, desired_status is the status value you want to filter by. The field is set to "order.status", which assumes your API supports filtering on this field in the OrderProduct resource. For more information, you can check the refine documentation on useTable (https://refine.dev/docs/data/hooks/use-table#filtering) and refine documentation on tables (https://refine.dev/docs/guides-concepts/tables#filtering-). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
