DataTableから項目を削除するかどうかをユーザーに尋ねるダイアログを実装しています。同意すると、叙事詩はDELETE要求をバックエンドに送信し、DataTableの状態を更新してリストを表示する必要があります削除されていないアイテム。私の問題は、DELETE_DATAアクションの実行を開始するDELETE_DATAアクションをディスパッチするAGREEオプションをクリックしなくても、DELETE_DATAアクションの実行を開始し、DELETEリクエストのストリームをバックエンドに送信するOPEN_DELETE_DIALOGアクションをディスパッチし、モーダルダイアログを開く叙事詩です。 。 叙事詩は、ユーザーがDELETE_DATAアクションをディスパッチしたときにのみDELETEリクエストを送信する必要があります。どのように達成できますか？redux-observableでDELETEアクションを作成するには？
これは私のダイアログコンポーネント（この場合には、それは役割を削除します）です：
：class DeleteDialog extends React.Component {
render() {
return (
<div>
<MenuItem onClick={_ => {
console.log(`Edit ${JSON.stringify(this.props.item)}`)
this.props.openDeleteDialog(this.props.item)
}}>
<IconButton aria-label="Edit">
<DeleteIcon />
</IconButton>
<Typography>
Delete
</Typography>
</MenuItem>
<Dialog open={this.props.open} onRequestClose={this.props.cancelDeleteData}>
<DialogTitle>{"Delete Alert"}</DialogTitle>
<DialogContent>
<DialogContentText>
Are you sure you want to delete: {this.props.item.name}
</DialogContentText>
</DialogContent>
<DialogActions>
<Button onClick={this.props.cancelDeleteData} color="primary">
Cancel
</Button>
<Button onClick={this.props.deleteData(this.props.item)} color="primary">
Agree
</Button>
</DialogActions>
</Dialog>
</div>
);
}
}
const mapStateToProps = state => ({
open: state.role.delete.open,
})
const mapDispatchToProps = dispatch => ({
...deleteDispatchesForScope(scopes.ROLE, dispatch)
})
これは私の行動の創造主である範囲はこのように上のユーザー、ロールとすることができるよう、それは一般的なもので
export const actionTypes = {
OPEN_DELETE_DIALOG: 'OPEN_DELETE_DIALOG',
DELETE_DATA: 'DELETE_DATA',
CANCEL_DELETE_DATA: 'CANCEL_DELETE_DATA'
}
export const deleteActionTypesForScope = scope => ({
OPEN_DELETE_DIALOG: `${scope}_${actionTypes.OPEN_DELETE_DIALOG}`,
DELETE_DATA: `${scope}_${actionTypes.DELETE_DATA}`,
CANCEL_DELETE_DATA: `${scope}_${actionTypes.CANCEL_DELETE_DATA}`
})
export const deleteActionForScope = scope => {
const actionTypes = deleteActionTypesForScope(scope);
return {
openDeleteDialog: item => ({
type: actionTypes.OPEN_DELETE_DIALOG,
item: item,
open: true
}),
deleteData: item => ({
type: actionTypes.DELETE_DATA,
item: item,
open: false
}),
cancelDeleteData: _ => ({
type: actionTypes.CANCEL_DELETE_DATA,
item: {},
open: false
})
}
}
export const deleteDispatchesForScope = (scope, dispatch) => {
const actionCreators = deleteActionForScope(scope);
return {
openDeleteDialog: item => dispatch(actionCreators.openDeleteDialog(item)),
deleteData: item => dispatch(actionCreators.deleteData(item)),
cancelDeleteData: _ => dispatch(actionCreators.cancelDeleteData())
}
}
そして、私のEPICはこれです：
歴史は私のDataTableのあるパスにリダイレクトconst deleteRolEpic = (action$, store) => (
action$.ofType(actionTypes.DELETE_DATA)
.filter(_ => !store.getState().rol.delete.loading)
.switchMap(action => {
let rolpath = 'roles/' + action.item.id;
return Observable.fromPromise(axios.delete(rolpath))
.map(response => {
history.push('/roles');
})
})
)
この場合、ロールのまた、Axiosを使用してバックエンドにリクエストを送信しています。
