Is there a way to make api call when expanding table to show nested table? - antd

Question

In Ant Nested table - When expanding a row, I want to make an api call and get the data to show the nested table.
The function expandedRowRender, expects to return the nested table, it does not accept a promise.
How can I show a nested Ant table using ajax call?
I have tried to recreate the scenario for reference.
import ReactDOM from "react-dom";
import "antd/dist/antd.css";
import "./index.css";
import { Table } from "antd";
import reqwest from "reqwest";
const nestedColumns = [
{
title: "Name",
dataIndex: "name",
sorter: true,
render: name => `${name.first} ${name.last}`,
width: "20%"
},
{
title: "Gender",
dataIndex: "gender",
filters: [
{ text: "Male", value: "male" },
{ text: "Female", value: "female" }
],
width: "20%"
},
{
title: "Email",
dataIndex: "email"
}
];
class App extends React.Component {
state = {
data: []
};
fetch = (params = {}) => {
console.log("params:", params);
reqwest({
url: "https://randomuser.me/api",
method: "get",
data: {
results: 10,
...params
},
type: "json"
}).then(data => {
return (
<Table
columns={nestedColumns}
dataSource={data.results}
pagination={false}
/>
);
// this.setState({
// data: data.results
// });
});
};
expandedRowRender = () => {
this.fetch();
return <table columns={nestedColumns} dataSource={this.state.data} />;
};
render() {
const columns = [
{ title: "Name", dataIndex: "name", key: "name" },
{ title: "Platform", dataIndex: "platform", key: "platform" },
{ title: "Version", dataIndex: "version", key: "version" }
];
const data = [
{
key: 1,
name: "Screem",
platform: "iOS",
version: "10.3.4.5654"
}
];
return (
<Table
columns={columns}
dataSource={data}
pagination={false}
expandedRowRender={this.expandedRowRender}
/>
);
}
}
ReactDOM.render(<App />, document.getElementById("container"));

I try my level best to answer your question. Here is the reduced type of code and you can get an idea of how to do that.
In state,
state = {
data: null,
loading: false,
};
Here is your function to make API call,
fetch = (expanded, record) => {
axios.get(`put your api to load nested table`)
.then(res => {
const data = res.data;
this.setState({
...this.state.data,
data,
loading: true
})
}).catch(error => {
console.log(error, "error")
})
}
After that,
expandedRowRender=() => {
if(this.state.loading){
const nestedTableData = this.state.data.map(row => ({
key: row.id,
Id: row.id,
name: 'test',
gender: 'gender',
}))
const nestedColumns = [
{ title: "Name", dataIndex: "name", key: "name" },
{ title: "Gender", dataIndex: "gender", key: "gender" },
];
return <Table columns={nestedColumns} dataSource={nestedTableData } pagination={false} />
}
};
And put following code below return
<Table
className="components-table-demo-nested"
columns={columns}
dataSource={tableData}
expandable={{
expandedRowRender: this.expandedRowRender,
rowExpandable: record => true,
onExpand: this.fetch
}}
/>
I hope it may help you and let me know if it does. :)
