how to filter data without using a table.

Hi @Alex YT. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Refine provides a way to handle client-side filtering without using a table. You can use the useTable hook from @refinedev/core to manage filters. First, you need to set filters.mode: "off" to disable server-side filtering.

import { useTable } from "@refinedev/core";  
const { tableQueryResult, filters, setFilters } = useTable({  
 filters: {  
 mode: "off",  
 },  
});

import { useTable } from "@refinedev/core";  
const { tableQueryResult, filters, setFilters } = useTable({  
 filters: {  
 mode: "off",  
 },  
});

Then, you can use the filters state to filter your data.

const List = () => {  
 const { tableQueryResult, filters } = useTable();  
  
 const filteredData = useMemo(() => {  
 if (filters.length === 0) {  
 return tableQueryResult.data;  
 }  
  
 const logicalFilters = filters.flatMap((item) => ("field" in item ? item : []));  
  
 return tableProps.dataSource.filter((item) => {  
 return logicalFilters.some((filter) => {  
 if (filter.operator === "eq") {  
 return item[filter.field] === filter.value;  
 }  
 });  
 });  
 }, [tableQueryResult.data, filters]);  
};

const List = () => {  
 const { tableQueryResult, filters } = useTable();  
  
 const filteredData = useMemo(() => {  
 if (filters.length === 0) {  
 return tableQueryResult.data;  
 }  
  
 const logicalFilters = filters.flatMap((item) => ("field" in item ? item : []));  
  
 return tableProps.dataSource.filter((item) => {  
 return logicalFilters.some((filter) => {  
 if (filter.operator === "eq") {  
 return item[filter.field] === filter.value;  
 }  
 });  
 });  
 }, [tableQueryResult.data, filters]);  
};

In this example, the data is filtered based on the filters state. The filters state is an array of filter objects, each containing a field, operator, and value. The useMemo hook is used to optimize performance by only re-computing the filtered data when the tableQueryResult.data or filters change. For more details, you can refer to the Refine documentation (https://refine.dev/docs/data/hooks/use-table#how-can-i-handle-client-side-filtering). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how about without truning off setFilters

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you want to filter data without turning off setFilters, you can use the setFilters function provided by the useTable or useSimpleList hooks. This function allows you to set the current filters state. Here's an example of how you can use setFilters with useSimpleList:

import { useSimpleList } from "@refinedev/antd";  
import { Typography, List, Input } from "antd";  

const { Text } = Typography;  

interface IProduct {  
 id: number;  
 name: string;  
 description: string;  
 price: string;  
}  

const ProductList: React.FC = () => {  
 const { listProps, setFilters } = useSimpleList<IProduct>({  
 filters: {  
 initial: [  
 {  
 field: "name",  
 operator: "contains",  
 value: "Awesome",  
 },  
 ],  
 },  
 });  

 return (  
 <div>  
 <Input.Search  
 placeholder="Search by name"  
 onChange={(e) => {  
 setFilters([  
 {  
 field: "name",  
 operator: "contains",  
 value: e.target.value,  
 },  
 ]);  
 }}  
 />  
 <List {...listProps} renderItem={renderItem} />  
 </div>  
 );  
};  

const renderItem = (item: IProduct) => {  
 const { id, name, description, price } = item;  

 return (  
 <List.Item actions={[<Text key={id}>{price}</Text>]}>  
 <List.Item.Meta title={name} description={description} />  
 </List.Item>  
 );  
};

import { useSimpleList } from "@refinedev/antd";  
import { Typography, List, Input } from "antd";  

const { Text } = Typography;  

interface IProduct {  
 id: number;  
 name: string;  
 description: string;  
 price: string;  
}  

const ProductList: React.FC = () => {  
 const { listProps, setFilters } = useSimpleList<IProduct>({  
 filters: {  
 initial: [  
 {  
 field: "name",  
 operator: "contains",  
 value: "Awesome",  
 },  
 ],  
 },  
 });  

 return (  
 <div>  
 <Input.Search  
 placeholder="Search by name"  
 onChange={(e) => {  
 setFilters([  
 {  
 field: "name",  
 operator: "contains",  
 value: e.target.value,  
 },  
 ]);  
 }}  
 />  
 <List {...listProps} renderItem={renderItem} />  
 </div>  
 );  
};  

const renderItem = (item: IProduct) => {  
 const { id, name, description, price } = item;  

 return (  
 <List.Item actions={[<Text key={id}>{price}</Text>]}>  
 <List.Item.Meta title={name} description={description} />  
 </List.Item>  
 );  
};

In this example, the setFilters function is used to update the filters state when the value of the search input changes. The new filters state is an array containing a single filter object, which specifies that the name field should contain the current value of the search input. For more details, you can refer to the Refine documentation (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-simple-list#filtering). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
