i'm having a table component for displaying some data. After dispatching an action the table data in the state are channging. However my table component is not updated. It is updated only when i click on another radio button in another row of my table. I want my component to rerender when the data are changed. Here is my code:
const mapStateToProps = state => ({
evaluationData: evaluationResultsSelector(state)
});
const mapDispatchToProps = dispatch => ({
setSelectedEvaluationRecord: record =>
dispatch(setSelectedEvaluationRecord(record))
});
export default connect(mapStateToProps,
mapDispatchToProps
EvaluationDataTable,
);
and my component is this:
import React from 'react';
import Table from 'antd/lib/table';
import 'antd/lib/table/style/css';
import antd/dist/antd.css;
import { columnEvaluation } from './evaluationDataStructure';
class EvaluationDataTable extends React.Component {
constructor(props) {
super(props);
this.state = {
selectedRowKeys: [0], // Check here to configure the default column
};
}
// shouldComponentUpdate(prevProps, prevState) {
// return (prevProps.results !== this.props.results || prevState.selectedRowKeys !== this.state.selectedRowKeys);
// }
onRowChange = selectedRowKeys => {
if (selectedRowKeys.length > 1) {
const lastSelectedRowIndex = [...selectedRowKeys].pop();
this.setState({ selectedRowKeys: lastSelectedRowIndex });
}
this.setState({ selectedRowKeys });
};
onRowSelect = (record) => {
this.props.setSelectedEvaluationRecord(record)
};
render() {
const { selectedRowKeys } = this.state;
const rowSelection = {
type: 'radio',
selectedRowKeys,
onChange: this.onRowChange,
onSelect: this.onRowSelect
};
return (
<React.Fragment>
<div style={{ marginBottom: 16 }} />
<Table
rowSelection={rowSelection}
columns={columnEvaluation}
dataSource={this.props.evaluationData}
/>
</React.Fragment>
);
}
}
export default EvaluationDataTable;
When i click in another row the table is rerendered as my setState is triggered but when the data are channged the table is not rerendered. Only when i click in another row. How to deal with it? Thanks a lot
Also my reducer which mutates the table is this:
case ACTION_TYPES.EDIT_EVALUATION_RESULTS: {
const evaluationResults = state.evaluationResults;
const editedRecord = action.payload.editedEvaluationData;
evaluationResults.forEach((item, i) => {
if (item.id === editedRecord.id) {
evaluationResults[i] = editedRecord;
}
});
return {
...state,
evaluationResults
};
}
