I'm building an application that uses react-google-maps integration component and I have created a Marker's custom property 'id'. I have to access the clustered markers on a marker clusterer's click, but I can't seem to access the custom property that I have created through getMarkers() method.
{props.clusters.map(cluster => (
<MarkerClusterer
averageCenter
enableRetinaIcons
gridSize={60}
onClick={(markerClusterer) => {
const clickedMarkers = markerClusterer.getMarkers()
}}
>
{cluster.markers.map(marker => (
<Marker
id={ marker.id}
position={{ lat: marker.lat, lng: marker.lng }}
/>
))}
</MarkerClusterer>
))}
Is there any other way to access the marker's custom property?
You could assign custom properties such as id via MarkerProps.options prop, like this:
<MarkerClusterer onClick={this.handleMarkerClustererClick}>
{this.props.markers.map(marker => (
<Marker
options = {{marker.id}}
key={index}
position={marker.ppos}
/>
))}
</MarkerClusterer>
These properties will be available through the marker instances when using MarkerClusterer.getMarkers method:
handleMarkerClustererClick(markerClusterer, pos) {
const clickedMarkers = markerClusterer.getMarkers();
for( let m of clickedMarkers){
console.log(m.id);
}
}
Here is a demo

I am working on a project that uses Google autocomplete to set locations. The project allows users to set pickup and destination location, and then they can also enter stop-by places up to additional 3, making it a total of 5.
Here's my sample code:
const placesRef = useRef([]);
const [stopspots, setStopSpots] = useState([]);
const [state, setState] = useState({
defaultPlacesInput: 'flex',
//and others
});
useEffect(() => {
placesRef.current = placesRef.current.slice(0, 5);
}, []);
const placesComponent = (i, placeholder) => {
return (<PlacesFrame key={i}>
...
<GooglePlacesAutocomplete
placeholder={placeholder}
minLength={2}
ref={el => placesRef.current[i] = el}
onPress={(data, details = null) => {
placesRef.current[i]?.setAddressText(data?.structured_formatting?.main_text);
setState({...state, defaultPlacesInput: 'flex'})
}}
enablePoweredByContainer={false}
fetchDetails
styles={{
textInput: [styles.input1,{paddingLeft:30}],
container: [styles.autocompleteContainer,{display:placesRef.current[i]?.isFocused() ? 'flex' : state.defaultPlacesInput}],
listView: styles.listView,
listView: styles.listView,
row: styles.row,
predefinedPlacesDescription: {
color: '#1faadb',
},
}}
query={{
key: GOOGLE_PLACES_API_KEY,
language: profile.language,
components: 'country:' + profile.iso,
}}
textInputProps={{
//value: '',
onChangeText: alterOtherFields
}}
renderRow={(data) => <PlaceRow data={data} />}
/>
...
</PlacesFrame>)
}
const stopByLocation = () => {
var counter = stopspots.length, obj = placesComponent(counter + 2, 'Drop off location');
setStopSpots([...stopspots, {
id: counter,
place: obj
}
])
}
And here is how the autocomplete component is rendered
return(
...
<View>
{placesComponent(0, 'Pick up location')}
{placesComponent(1, 'Drop off location')}
</View>
...
)
The output look like this
Everything works perfect when I call the placesComponent() function directly. But like I mentioned earlier, I want the users to be able to add up to 3 additional stop by locations, and because it is optional, additional fields is added by appending to hook, and then rendered. the code looks like this.
return(
...
<View>
{placesComponent(0, 'Pick up location')}
{placesComponent(1, 'Drop off location')}
//This will append more placed fields
{stopspots != '' ?
stopspots.map((item : {}) => ((item.place)))
: null}
<ClickableButton>
<TouchableOpacity activeOpacity={0.6} onPress={() => stopByLocation()}><AddPlaces><AntDesign name="plus" size={10} color="#444" /> Add</AddPlaces></TouchableOpacity>
</ClickableButton>
</View>
...
)
The outcome looks like this
I observed that each component binded to the hooks takes the early properties, and does not effect additional changes. While the first two fields rendered by calling the function directly does.
When I make changes to state.defaultPlacesInput (observe this in styles property of GooglePlacesAutocomplete), the changes only effect on the two components called directly.
Is there a module, or a systematic way to append the renderer function call, without using useState hooks to append the 3 additional fields?
Is it possible to expose stored properties in useState hooks to respond as the other two which observe the state changes? If yes, how?
Any contribution, suggestion will be accepted
I'm a totally newbie with React and React-Admin. IMHO, I'm trying to achieve something simple that many people must have already done but I cannot find any kind of tutorial anywhere.
I'd like to add another button to the list of action buttons (show/edit) within each row in a <List> component. This button would archive the record.
My last try looks like the code below.
import React from 'react';
import {
Datagrid,
EmailField,
List,
TextField,
ShowButton,
EditButton,
DeleteButton,
CloneButton,
} from 'react-admin';
import { makeStyles } from '#material-ui/core/styles';
import ArchiveIcon from '#material-ui/icons/Archive';
const useRowActionToolbarStyles = makeStyles({
toolbar: {
alignItems: 'center',
float: 'right',
width: '160px',
marginTop: -1,
marginBottom: -1,
},
icon_action_button: {
minWidth: '40px;'
},
});
const ArchiveButton = props => {
const transform = data => ({
...data,
archived: true
});
return <CloneButton {...props} transform={transform} />;
}
const RowActionToolbar = (props) => {
const classes = useRowActionToolbarStyles();
return (
<div className={classes.toolbar}>
<ShowButton label="" basePath={props.basePath} record={props.record} className={classes.icon_action_button}/>
<EditButton label="" basePath={props.basePath} record={props.record} className={classes.icon_action_button}/>
<ArchiveButton {...props} basePath={props.basePath} label="" icon={<ArchiveIcon/>} record={props.record} className={classes.icon_action_button} />
<DeleteButton basePath={props.basePath} label="" record={props.record} className={classes.icon_action_button}/>
</div>
);
};
export const UserList = props => {
return (
<List
{...props}
sort={{ field: 'first_name', order: 'ASC' }}
>
<Datagrid>
<TextField source="first_name"/>
<TextField source="last_name"/>
<EmailField source="email"/>
<RowActionToolbar/>
</Datagrid>
</List>
)
};
Obviously, this code does not work because the <CloneButton> component get rid of the id the record. Moreover, except if I did something wrong - which is totally possible -, it makes a GET request to a create endpoint.
I'm using different routes in my dataProvider (The back end is using Django and Django rest framework). I want to send a PATCH to the detail endpoint, like the <Edit> component does.
I also tried with a <SaveButton>, but it fails too.
Uncaught TypeError: Cannot read property 'save' of undefined
at useSaveContext (SaveContext.js:23)
I guess the <SaveButton> must be within a <SimpleForm>?
I'd like the save behaviour of the <DeleteButton>, i.e. update the record from the list, display the notification that the record has been archived (with the Undo link), send the request to the back end, refresh the list.
Any guidance, directions would be very appreciated.
I don't know that this is a full answer, but felt like more than a comment...
You are trying to archive the existing record, not create a whole new record, right? CloneButton is supposed to be used to create a new record with a new ID (which is why your ID is going away), so you don't want to us it here. note that I've never used CloneButton. it is not fully documented so I could be wrong about its use.
I am thinking that you should use the useRecordContext hook within your Archive button to pull in all of the record's data, including the id; read this little section: https://marmelab.com/react-admin/Architecture.html#context-pull-dont-push
And I don't think transform is what you're looking for here. You will need to use one of the dataProvider hooks, i'm assuming useUpdate: https://marmelab.com/react-admin/Actions.html#useupdate
//first create component
const MyButton = (props: any) => {
const [sendEmailLoading, setSendEmailLoading] =
React.useState<boolean>(false);
const record = useRecordContext(props);
const sendEmail = (id: Identifier) => {
setSendEmailLoading(true)
dataProvider.sendEmail(
"notifications", { id: id })
.then(({ data }: any) => {
if (data && data.status == "success")
notify('Email send success', { type: 'success' });
setSendEmailLoading(false);
refresh();
});
};
return (
<ButtonMUI color='primary' size="small" onClick={() => {
sendEmail(record.id) }}>
{
!record.publish &&(
!sendEmailLoading ? (
translate('resources.notifications.buttons.send')
) : (
<CircularProgress size={25} thickness={2} />
)
)
}
</ButtonMUI>
)
}
//and second add to datagrid list
<Datagrid>
<NumberField source="id" />
<TextFieldRA source="subject" />
<DateField source="date" />
<BooleanField source="publish" />
{/* <EditButton /> */}
<ShowButton />
<MyButton />
</Datagrid>
I was trying to find any tutorial about the implementation of react-native-snap-carousel example but I couldnt find any. If any of you have seen any tutorials on this, please suggest a link.
I have been through its documentation and examples provided by the creators of it, however they look very complicated to me.
you have to provide data and it will do automatically mapping and assign functional component to render item it will return json format with index and item you can see below example
const container = ({edges,_loadmore,navigation}) =>{
const _renderItem = ({ item, index }) => {
return (
<View>
<Render_component />
</View>
);
};
return (
<Carousel
onSnapToItem={slideIndex => {
setcurrentSlider(slideIndex);
_loadMore();
}}
onBeforeSnapToItem={slideIndex => {
setBeforeSlider(slideIndex);
}}
inactiveSlideOpacity={1}
inactiveSlideScale={1}
enableSnap
ref={carRef}
data={edges}
renderItem={_renderItem}
sliderHeight={screenHeight}
itemHeight={screenHeight}
vertical={true}
/>
)
}
I want to get checked friends using checkbox. But I not quite sure how i will achieve it, hope someone can help me.
This is my state:
state = {checked: false}
This is where I want to map array
{this.props.navigation.getParam('friends').map((name, key) => (
<View>
<Text>{name}</Text>
<CheckBox
checked={this.state.checked}
onPress={(val)=>{}}
/>
</View>))}
Note: Or Could someone write me an app/code snippet in snack.expo.io how to get only checked checkbox value
You can write a custom checkbox component
export default class CustomCheckbox extends Component {
constructor(props) {
super(props);
this.state = {
checked: false,
};
}
toggleChange(){
this.setState({checked: !this.state.checked});
}
render() {
return (
<View>
<Text>{this.props.name}</Text>
<CheckBox
checked={this.state.checked}
onPress={() => this.bind.toggleChange(this)}
/>
</View>
);
}
}
and import your CustomCheckbox component
import CustomCheckbox from "your CustomCheckbox.js path"
{this.props.navigation.getParam('friends').map((name, key) => (
<View>
<CustomCheckbox name={name} />
</View>
))}
Your code is pretty good to go, you just need to update a bit. You have following two options:
Your friend's array should have checked key within each containing object, then you can simply do something like this.
{
this.props.navigation.getParam('friends').map((item, key) => (
let {name, checked} = item // item is an object from friends array,the and it have name, checked and other keys
<View>
<Text>{name}</Text>
<CheckBox
checked={checked}
onPress={(val)=>{}}
/>
</View>))
}
Other is you to save the name of the person as key and true/false as the checked state, eg :
toggleCurrentFirendState = (item)=>{
this.setState((prevState)=>{
let {name} = item //get name from clicked friend from the list
return {
...prevState, //used spread operator, so that other states doesn't get mutat.
[name]:!prevState[name] //toogle state of clicked item
}
})
}
//within your render
{
this.props.navigation.getParam('friends').map((item, key) => (
let {name} = item // item is an object from friends array,the and it have name, checked and other keys
<View>
<Text>{name}</Text>
<CheckBox
checked={name ===this.state[name]} //see change
onPress={(val)=>{this.toggleCurrentFirendState(item)}}
/>
</View>))
}
I have a component that renders out a list of buttons, lets call this 'ButtonList'. When one of the buttons is clicked, the event is bubbled up like so:
<ButtonList onButtonPressed={(mins) => { console.log(mins); }} />
In response to this, I want to hide that ButtonList and show another component that is currently hidden. The ButtonList has some state such as "state { visible: true }" that I want to toggle that stops it rendering. How do I make a call to toggle the state of that ButtonList and then also call my other component in this view to also toggle its visible state to show?
Thanks.
swappingComponentsExample = () => {
return (
<View>
{this.state.showButtonList ? (
<ButtonList
onButtonPressed={mins => {
this.setState({showButtonList: false});
console.log(mins);
}}
/>
) : (
<OtherComponent />
)}
</View>
);
};
// Renders both components but passes style override to hide the object
// ButtonList/OtherComponent are not destroyed and recreated using this method
hidingExample = () => {
return (
<View>
<ButtonList
onButtonPressed={mins => {
this.setState({showButtonList: false});
console.log(mins);
}}
style={!this.state.showButtonList && {display: 'none'}}
/>
<OtherComponent
style={this.state.showButtonList && {display: 'none'}}
/>
</View>
);
};
