Hi @Sly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- I'm sorry, but the provided extracts do not contain information on how to use the useSelect hook with Ant Design's Radio component. The extracts only provide information on how to use useSelect with Ant Design's Select component and other form-related hooks provided by @refinedev/antd. For more information, you may want to refer to the official documentation of Refine and Ant Design: - Refine's useSelect documentation (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-select) - Ant Design's Radio component documentation (https://ant.design/components/radio/) Please note that the useSelect hook is designed to manage select-like components, and may not be directly applicable to a Radio component. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai is possible to show the first fecthed data of the selectProps in the placeholder?

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, it is possible to show the first fetched data of the selectProps in the placeholder. However, you would need to manage this manually. The useSelect hook does not provide this functionality out of the box. Here's a basic example of how you might achieve this:

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps, data } = useSelect<ICategory>({  
 resource: "categories",  
 });  

 const placeholder = data?.[0]?.title || "Select a category";
  
 return <Select placeholder={placeholder} style={{ width: 300 }} {...selectProps} />;  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps, data } = useSelect<ICategory>({  
 resource: "categories",  
 });  

 const placeholder = data?.[0]?.title || "Select a category";
  
 return <Select placeholder={placeholder} style={{ width: 300 }} {...selectProps} />;  
};

In this example, we're using the data returned from useSelect to set the placeholder to the title of the first category. If no data is available, the placeholder will default to "Select a category". Please note that this is a simplified example and may not cover all edge cases. You should adjust the code to fit your specific needs and handle potential issues such as data fetching errors or an empty data array. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I get this error: Property 'data' does not exist on type 'UseSelectReturnType<BaseRecord, BaseOption>

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The error message you're seeing is because the useSelect hook does not return a data property. Instead, it returns an object with options and selectProps properties. Here's the correct way to use the useSelect hook:

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps, options } = useSelect<ICategory>({  
 resource: "categories",  
 });  

 const placeholder = options?.[0]?.label || "Select a category";
  
 return <Select placeholder={placeholder} style={{ width: 300 }} {...selectProps} />;  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps, options } = useSelect<ICategory>({  
 resource: "categories",  
 });  

 const placeholder = options?.[0]?.label || "Select a category";
  
 return <Select placeholder={placeholder} style={{ width: 300 }} {...selectProps} />;  
};

In this example, we're using the options returned from useSelect to set the placeholder to the label of the first option. If no options are available, the placeholder will default to "Select a category". For more information, refer to the useSelect documentation (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-select/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Still having error: Property 'options' does not exist on type 'UseSelectReturnType<BaseRecord, BaseOption>'

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I apologize for the confusion. The useSelect hook does not directly return an options property. Instead, it returns selectProps which you can spread into your Select component. The options are included within these selectProps. Here's an example of how you can use useSelect:

import { useSelect } from "@pankod/refine";

const { selectProps } = useSelect({
    resource: "categories",
});

return <Select {...selectProps} />;

import { useSelect } from "@pankod/refine";

const { selectProps } = useSelect({
    resource: "categories",
});

return <Select {...selectProps} />;

In this example, selectProps is an object that includes all the necessary props for the Select component, including the options. If you want to customize the placeholder based on the fetched data, you might need to handle this outside of the useSelect hook, as it doesn't provide direct access to the fetched data. For more information, please refer to the useSelect documentation (https://refine.dev/docs/data/hooks/use-select/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How to set limit on maping itens in pdf: {itens?.map((item, index) => ( <View style={styles.tableRow} key={index} > <View style={styles.indexCol}> <Text style={styles.tableCell}> {index + 1}
</Text> </View> <View style={styles.numberCodCol}> <Text style={styles.tableLeftCenterCell}> {item.rqp_produto_id.cod} </Text> </View> ))}

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You can limit the number of items being mapped by using the slice method on the array. The slice method returns a shallow copy of a portion of an array into a new array object selected from start to end (end not included) where start and end represent the index of items in that array. The original array will not be modified. Here's how you can do it:

{itens?.slice(0, limit).map((item, index) => (
    <View
        style={styles.tableRow}
        key={index}
    >
        <View style={styles.indexCol}>
            <Text style={styles.tableCell}>
                {index + 1}
            </Text>
        </View>

        <View style={styles.numberCodCol}>
            <Text style={styles.tableLeftCenterCell}>
                {item.rqp_produto_id.cod}
            </Text>
        </View>
    </View>
))}

{itens?.slice(0, limit).map((item, index) => (
    <View
        style={styles.tableRow}
        key={index}
    >
        <View style={styles.indexCol}>
            <Text style={styles.tableCell}>
                {index + 1}
            </Text>
        </View>

        <View style={styles.numberCodCol}>
            <Text style={styles.tableLeftCenterCell}>
                {item.rqp_produto_id.cod}
            </Text>
        </View>
    </View>
))}

In this example, limit is the maximum number of items you want to map. Replace it with the actual limit you want to set. For more information on the slice method, you can refer to this blog post (https://refine.dev/blog/javascript-splice-method#introduction) on the Refine website. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Cannot find name 'limit'

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The error message "Cannot find name 'limit'" means that the variable limit is not defined in your code. You need to define limit before using it in the slice method. Here's an example of how you can define limit:

const limit = 10; // Replace 10 with the actual limit you want to set

{{itens?.slice(0, limit).map((item, index) => (
    <View
        style={{styles.tableRow}}
        key={{index}}
    >
        <View style={{styles.indexCol}}>
            <Text style={{styles.tableCell}}>
                {{index + 1}}
            </Text>
        </View>

        <View style={{styles.numberCodCol}}>
            <Text style={{styles.tableLeftCenterCell}}>
                {{item.rqp_produto_id.cod}}
            </Text>
        </View>
    </View>
))}}

const limit = 10; // Replace 10 with the actual limit you want to set

{{itens?.slice(0, limit).map((item, index) => (
    <View
        style={{styles.tableRow}}
        key={{index}}
    >
        <View style={{styles.indexCol}}>
            <Text style={{styles.tableCell}}>
                {{index + 1}}
            </Text>
        </View>

        <View style={{styles.numberCodCol}}>
            <Text style={{styles.tableLeftCenterCell}}>
                {{item.rqp_produto_id.cod}}
            </Text>
        </View>
    </View>
))}}

In this example, limit is set to 10, which means that only the first 10 items in the itens array will be mapped. You can replace 10 with the actual limit you want to set. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to use this tableQueryResult?.data?.data.reduce((total, item) => total + item.subTotal, 0); to calculate sliced itens limit to 10

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You can use the slice method to limit the items before using reduce to calculate the total. Here's how you can do it:

const limit = 10; // Replace 10 with the actual limit you want to set

const total = tableQueryResult?.data?.data.slice(0, limit).reduce((total, item) => total + item.subTotal, 0);

const limit = 10; // Replace 10 with the actual limit you want to set

const total = tableQueryResult?.data?.data.slice(0, limit).reduce((total, item) => total + item.subTotal, 0);

In this example, limit is set to 10, which means that only the first 10 items in the tableQueryResult.data.data array will be included in the calculation. You can replace 10 with the actual limit you want to set. Please note that this code assumes that tableQueryResult.data.data is an array and each item in the array has a subTotal property. If that's not the case, you may need to adjust the code to fit your specific needs. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
