React mapping rendering issue

I'm having a very perplexing issue that I wonder if anyone could help with. I have objects being mapped as arrays into some html(/jsx). The objects aren't rendering. Strangely, though, in the debugger it does show each value being attributed to the insertions in the html -- but it's not rendering. any ideas?
The picture below is an example of one object in the reservations array showing as mapping in the debugger, whereas the rendering actually stays as the second picture.
The axios http request, in a promise with another request:
const getReservations =
axios
.get(`${api_url}/reservations`, {
headers: {
'Authorization': `Bearer ${sessionStorage.token}`
}
})
.then((res) => {
setReservations(reservations => ([...reservations, ...res.data]));
})
const getRoomTypes =
axios
.get(`${api_url}/room-types`, {
headers: {
'Access-Control-Allow-Origin': `${ui_url}`,
'Authorization': `Bearer ${sessionStorage.token}`
}
})
.then((res) => {
setRoomTypes(roomTypes => ([...roomTypes, ...res.data]));
})
Promise.all([getReservations, getRoomTypes])
.catch(() => {
setError(connectionError);
});
}, []);
Which passes the data to the rendered component:
return (
<div>
<h2>Reservations</h2>
<Link className="button" to="/reservations/create">Create</Link>
<br />
<br />
<ReservationDiv error={error} resData={reservations} />
</div>
);
The component in which the objects are rendered:
const ReservationDiv = (props) => {
const reservations = props.resData;
const renderTableData = () => {
reservations.map((reservation) => {
const { id, user, guestEmail, roomTypeId, checkInDate,
numberOfNights } = reservation;
return (
<tr key={id}>
<td className="res">{id}</td>
<td className="user">{user}</td>
<td className="email">{guestEmail}</td>
<td className="room">{roomTypeId}</td>
<td className="date">{checkInDate}</td>
<td className="nights">{numberOfNights}</td>
</tr>
);
});
}
return (
<table>
<tbody>
<tr>
<th>ID</th>
<th>Input by</th>
<th>Guest Email</th>
<th>Room Type</th>
<th>Check-in Date</th>
<th># of Nights</th>
<th>Total</th>
</tr>
{renderTableData()}
</tbody>
</table>
);
}
I can also provide quoted code, but I figured the problem seems to be something more fundamental, since it's a difference between a representation of a thing and the thing itself

You need to return the mapped array of JSX objects
const renderTableData = () => {
return reservations.map((reservation) => {
//...

Search in custom table - React

I'm trying to make a table with api data searchable. I'm on my way, but unsure on how to proceed further.
Code looks like this:
const [searchTerm, setSearchTerm] = useState("");
const [searchResults, setSearchResults] = useState([]);
const handleChange = event => {
setSearchTerm(event.target.value);
};
useEffect(() => {
const results = apiData.filter(person =>
person.toLowerCase().includes(searchTerm)
);
setSearchResults(results);
}, [searchTerm]);
const renderPerson = (contact, index) => {
return (
<tr key={index}>
<td>{contact.ID}</td>
<td>{contact.Info.Name}</td>
<td>{contact.InfoID}</td>
<td>{contact.Info.DefaultEmail.EmailAddress}</td>
<td>{contact.Info.DefaultPhone.Number}</td>
<td>{contact.Info.InvoiceAddress.AddressLine1}</td>
</tr>
)
}
return (
<Fragment>
<input type="text" value={searchTerm} onChange={handleChange} placeholder="Søk.."></input>
<table id="myTable">
<thead>
<tr className="header">
<th>ID</th>
<th>Navn</th>
<th>Info Id</th>
<th>E-post</th>
<th>Telefon</th>
<th>Adresse</th>
</tr>
</thead>
<tbody>
{apiData.map(renderPerson)}
</tbody>
</table>
</Fragment>
)
https://dev.to/asimdahall/simple-search-form-in-react-using-hooks-42pg
I've followed this guide, but since I have the renderPerson function, I'm a bit unsure on how to handle this.
Question: Is there any way to get this working, or am I approaching it the wrong way? I'm aware that I need to put searchResult in the tbody somehow, but then the table won't be populated.
Any help is much appreciated
Edit: displaying code for getting apiData:
useEffect(() => {
getContacts()
}, [])
const getContacts = () => {
$.ajax({
url: `http://localhost:5000/getContacts`,
type: "POST",
data: ajaxObj,
success: (data) => {
let response = JSON.parse(data)
setApiData(response)
setLoading(false)
},
error: () => {
console.log("noe feilet?");
}
});
}
console.log(apiData)
Data looks like this:
data

Change apiData to searchResults on render
<tbody>
{searchResults.map(renderPerson)}
</tbody>
Change your filter way result (Updated)
const results = apiData.filter(person =>
person.Info.Name.toLowerCase().includes(searchTerm)
);
....
const renderPerson = (item, index) => {
return (
<tr key={index}>
<td>{item.ID}</td>
<td>{item.Info.Name}</td>
<td>{item.InfoID}</td>
<td>{item.Info.DefaultEmail.EmailAddress}</td>
<td>{item.Info.DefaultPhone.Number}</td>
<td>{item.Info.InvoiceAddress.AddressLine1}</td>
</tr>
)
}

Try this
export default function () {
const [searchTerm, setSearchTerm] = useState("");
const [searchResults, setSearchResults] = useState([]);
const apiData=[
{
ID:'1222',
Info:{
ID:'1222',
EmailAddress:'test#test.com',
Number:'2222222222',
AddressLine1:'test'
}
},
{
ID:'2333',
Info:{
ID:'2333',
EmailAddress:'test2#test.com',
Number:'1111111111',
AddressLine1:'test2'
}
}
]
const handleChange = event => {
setSearchTerm(event.target.value);
if(event.target.value){
const results = apiData.filter(person =>
person.ID.toLowerCase().includes(event.target.value)
);
setSearchResults(results);
}else{
setSearchResults([]);
}
};
const renderPerson = (contact, index) => {
return (
<tr key={index}>
<td>{contact.ID}</td>
<td>{contact.Info.Name}</td>
<td>{contact.Info.ID}</td>
<td>{contact.Info.EmailAddress}</td>
<td>{contact.Info.Number}</td>
<td>{contact.Info.AddressLine1}</td>
</tr>
)
}
return (
<Fragment>
<input type="text" value={searchTerm} onChange={handleChange} placeholder="Søk.."></input>
<table id="myTable">
<thead>
<tr className="header">
<th>ID</th>
<th>Navn</th>
<th>Info Id</th>
<th>E-post</th>
<th>Telefon</th>
<th>Adresse</th>
</tr>
</thead>
<tbody>
{searchResults.map(renderPerson)}
</tbody>
</table>
</Fragment>
)
}

How can I sort column in child component clicking on heading in parent component?

The problem is I don't know how to put effect from parent component to child component...
I'm creating sorting function.
tableSort = (event, sortKey) => {
const {data} = this.state;
data.sort((a,b) => a[sortKey].localeCompare(b[sortKey]) )
this.setState({ data })
}
and then I'm trying to render that in my table
render() {
const {data} = this.state
return (
<>
<Table>
<Thead>
<Tr>
<Th onClick={e => this.tableSort(e, 'pool number')}>Pool Number</Th>
<Th>Sender</Th>
<Th>Not Routed Reason</Th>
<Th>Sent Date Time</Th>
<Th>Requested Delivery Report Mask Text</Th>
<Th>Delivery Report Received Date Time</Th>
<Th>isUnicode</Th>
<Th>MessageUUID</Th>
</Tr>
</Thead>
{this.renderData(data)}
</Table>
</>
)
}
The child component is called in this component and it locks like this..
import React from 'react'
import { Tbody, Tr, Td } from 'react-super-responsive-table'
const TablePageList = ({data}) => {
const {poolNumber, sender, notRoutedReason, sentDateTime, requestedDeliveryReportMaskText,
deliveryReportReceivedDateTime, isUnicode, messageUUID} = data
return (
<Tbody>
<Tr>
<Td>{poolNumber}</Td>
<Td>{sender}</Td>
<Td>{notRoutedReason}</Td>
<Td>{sentDateTime}</Td>
<Td>{requestedDeliveryReportMaskText}</Td>
<Td>{deliveryReportReceivedDateTime}</Td>
<Td>{isUnicode}</Td>
<Td>{messageUUID}</Td>
</Tr>
</Tbody>
)
}
export default TablePageList
So how can I access and sort my Td from Th?

You should call the child component from parent. You didn't call any child component.
Try below code.
import child compenent url.
import TablePageList from "./TablePageList";
And then keep state data.
this.state = {
data:[]
}
Also change function setState and order data.
tableSort = (event, sortKey) => {
const {data} = this.state;
data.sort((a,b) => a[sortKey].localeCompare(b[sortKey]) )
this.setState({ data: data })
}
And call TablePageList component below </Thead>
render() {
const { data } = this.state;
return (
<Table>
<Thead>
<Tr>
<Th onClick={e => this.tableSort(e, "pool number")}>
Pool Number
</Th>
<Th>Sender</Th>
<Th>Not Routed Reason</Th>
<Th>Sent Date Time</Th>
<Th>Requested Delivery Report Mask Text</Th>
<Th>Delivery Report Received Date Time</Th>
<Th>isUnicode</Th>
<Th>MessageUUID</Th>
</Tr>
</Thead>
{data.map(element => {
<TablePageList data={element}></TablePageList>;
})}
</Table>
);
}
And then you get data and fill it.
const TablePageList = ({ data }) => {
return (
<Tbody>
<Tr>
<Td>{data.poolNumber}</Td>
<Td>{data.sender}</Td>
<Td>{data.notRoutedReason}</Td>
<Td>{data.sentDateTime}</Td>
<Td>{data.requestedDeliveryReportMaskText}</Td>
<Td>{data.deliveryReportReceivedDateTime}</Td>
<Td>{data.isUnicode}</Td>
<Td>{data.messageUUID}</Td>
</Tr>
</Tbody>
);
};

How to display data with id React Js and Firebase

I'm working on a project, and I would like to display some data from my firebase database,
I can show some of them, but I want to display the rest of the data of my "listClients" on a box, linked to the checkbox with the id.
listClients.js it's where i map the data from the db
import React, { Component } from "react";
import * as firebase from "firebase";
import { Table, InputGroup } from "react-bootstrap";
class ListClients extends React.Component {
state = {
loading: true
};
componentWillMount() {
const ref = firebase.database().ref("listClients");
ref.on("value", snapshot => {
this.setState({ listClients: snapshot.val(), loading: false });
});
}
render() {
if (this.state.loading) {
return <h1>Chargement...</h1>;
}
const clients = this.state.listClients.map((client, i) => (
<tr key={i}>
<td>
<input id={client.id} type="checkbox" onChange={this.cbChange} />
</td>
<td>{client.nom}</td>
<td>{client.prenom}</td>
</tr>
));
const clientsAdresses = this.state.listClients.map((clientAdresse, i) => (
<tr key={i}>
<td id={clientAdresse.id}>{clientAdresse.adresse}</td>
</tr>
));
return (
<>
<Table className="ContentDesign" striped bordered hover>
<thead>
<tr>
<th></th>
<th>First Name</th>
<th>Last Name</th>
</tr>
</thead>
<tbody>{clients}</tbody>
</Table>
<Table className="ContentDesign" striped bordered hover>
<thead>
<tr>
<th>Adresse : </th>
</tr>
</thead>
<tbody>{clientsAdresses}</tbody>
</Table>
</>
);
}
}
export default ListClients;
my data :
I only want the "adresse" of the id where the checkbox is check
Thank you
ERROR :

To retrieve the adresse from the database then use the following code:
componentWillMount() {
const ref = firebase.database().ref("listClients");
ref.on("value", snapshot => {
snapshot.forEach((subSnap) => {
let address = subSnap.val().adresse;
});
});
}
First add a reference to node listClients the using forEach you can iterate and retrieve the adresse
If you want to get the adresse according to the id, then you can use a query:
const ref = firebase.database().ref("listClients").orderByChild("id").equalTo(0);

Filter method on another method?

I want to run a filter method on the renderTable method that I've defined below. Is it possible to do:
renderTable().filter(x => x.name)?
Right now, I have a table with rows of each category and their results from a url that provided some json data.
I would like to make a feature that allows users to adjust the setting to return their desired results.
CODE
const renderTable = () => {
return players.map(player => {
return (
<tr>
<td>{player.name}</td>
<td>{player.age}</td>
<td>{player.gender}</td>
<td>{player.state}</td>
<td>{player.status}</td>
</tr>
)
})
}
return (
<div className = "App">
<h1>Players</h1>
<table id = "players">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
<th>Gender</th>
<th>State</th>
<th>Status</th>
</tr>
</thead>
<tbody>{renderTable()}</tbody>
</table>
</div>
);

You can apply the filter before the map. Here, give this a try:
const renderTable = () => {
return players
.filter(player => player.state === "NSW")
.map(player => {
return (
<tr>
<td>{player.name}</td>
<td>{player.age}</td>
<td>{player.gender}</td>
<td>{player.state}</td>
<td>{player.status}</td>
</tr>
);
});
};
Here's a Working Sample CodeSandbox for your ref.

Yes you can. Just filter before map players.filters(...).map. But this is better
const renderTable = () => {
const rows = []
players.forEach((player, index) => {
if(player.name) {
rows.push(
<tr key={index}>
<td>{player.name}</td>
<td>{player.age}</td>
<td>{player.gender}</td>
<td>{player.state}</td>
<td>{player.status}</td>
</tr>
)
}
})
return rows;
}
