Passing value of component to another Scene to use in post method - react native - react-native

I need Some Help as possible.
In my code I have scene that return into my view, an array with names. However, I want to do something also. When I click the name, I want to take the email of the name I have clicked and past to my post method, to return in another scene with information of the email person. Here is my code:
My Users Class with all elements
import React from 'react';
import ListaItens from './ListaUsers'
import BarraNavegacao from './BarraNavegacao';
import {View,Image,Alert,TouchableHighlight,AsyncStorage} from 'react-native';
import axios from 'axios';
export default class Users extends React.Component {
constructor(props) {
super(props);
this.state = {tituloBarraNav: 'Colaboradores',testLocal:''};
}
My refresh function is into Component Users
async refresh() {
let tmp_localData = {};
AsyncStorage.getItem('localData', (err, result) => {
//console.log(result);
tmp_localData = JSON.parse(result);
//console.log('Local temp: ', tmp_localData.User.email);
}).then((result) => {
tmp_localData = JSON.parse(result);
//console.log('Email: ', tmp_localData.email);
axios({
method: 'post',
url: 'my url'
data: {
email: 'someEmail#test.com,
}
},
console.log('aqui esta o email'),
).then((response) => {
//console.log('Get tmpLocal ----------',tmp_localData);
//console.log('Get response ----------',response);
tmp_localData.User = {
"userID": response.data.response.userID,
"displayName": response.data.response.displayName,
"email": response.data.response.email,
"avatar": response.data.response.avatar,
"gender": response.data.response.gender,
"Session": {
"token": response.data.response.token,
},
"FootID": response.data.response.FootID,
};
//this.refresh();
//console.log('Set tmpLocal',tmp_localData);
AsyncStorage.setItem('localData', JSON.stringify(tmp_localData), () => {
}).then((result) => {
this.props.navigator.push({id: 'MenuPrincipal'});
console.log('Navigator',this.props.navigator);
//Alert.alert('Clicou Aqui ');
});
}).catch((error) => {
if (error.response) {
// The request was made and the server responded with a status code
// that falls out of the range of 2xx
console.log(error.response.data);
console.log(error.response.status);
console.log(error.response.headers);
Alert.alert('Não foi possivel mudar o utilizador');
} else if (error.request) {
// The request was made but no response was received
// `error.request` is an instance of XMLHttpRequest in the browser and an instance of
// http.ClientRequest in node.js
console.log('erro de ligaçao', error.message);
Alert.alert('Não foi possivel mudar o utilizador');
console.log(error.request);
} else {
// Something happened in setting up the request that triggered an Error
console.log('erro de codigo no then', error.message);
Alert.alert('Não foi possivel mudar o utilizador');
}
console.log(error.config);
Alert.alert('Não foi possivel mudar o utilizador');
});
});
}
My render in Users
render(){
const {principal, conteudo,imgConteudo1,imgConteudo2, texto,box}= myStyle;
return(
<View style={principal}>
<BarraNavegacao back navigator={this.props.navigator} tituloProp={this.state.tituloBarraNav}/>
<TouchableHighlight onPress={() => {this.refresh();}}
clearButtonMode={'while-editing'}
activeOpacity={1} underlayColor={'white'}>
<ListaItens/>
</TouchableHighlight>
</View>
);
}
}
I have ListaItems Component that will walk through an array and will put inside ScroolView with map method. So the code is:
My ListaItems Class
import React from 'react';
import { ScrollView} from 'react-native';
import axios from 'axios';
import Items from './Items';
export default class ListaItens extends React.Component {
constructor(props) {
super(props);
this.state = {listaItens: [], listaEmail: [] };
}
componentWillMount() {
//request http
axios.get('my url')
.then((response) => {
this.setState({listaItens: response.data.response})
})
.catch(() => {
console.log('Erro ao imprimir os dados')
});
}
render() {
return (
<ScrollView>
{this.state.listaItens.map(item =>(<Items key={item.email} item={item}/>))}
</ScrollView>
);
}
}
The last component is the component the build what i want to show inside scrollview in ListaItems. The component name is Items. the code is:
My Items Class
import React, {Component} from 'react';
import {Text, Alert, View, Image,} from 'react-native';
export default class Items extends Component {
constructor(props) {
super(props);
this.state = {listaEmail: ''};
}
render() {
const {foto, conteudo, texto, box, test} = estilo;
return (
<View>
<Text/>
<Text/>
<View style={conteudo}>
<Image style={foto} source={{uri: this.props.item.avatar}}/>
<Text style={texto}>{this.props.item.displayName}</Text>
</View>
<View style={test}>
<Text style={texto}>{this.props.item.email}</Text>
</View>
</View>
);
}
}
So, in Users Class for refresh() function in the post method on this email: "someEmail#test.com", I want to be dynamic, when I click the name of a person in Items Class, I want to take the the email here on this.props.item.email and put in parameter on post method of Users Class----refresh()----axios()---Data---email:the email i want to past.
A litle help here, please. I am desperate right now because i have tryied and I did not make it

First move the Touchable to the item
export default class Items extends Component {
render() {
const { foto, conteudo, texto, box, test } = estilo;
return (
<View> //I'm not sure if the this.props.item.email is the one you use, just change it if you need.
<TouchableHighlight onPress={() => { this.props.callback(this.props.item.email); }}
clearButtonMode={'while-editing'}
activeOpacity={1} underlayColor={'white'}>
<Text />
<Text />
<View style={conteudo}>
<Image style={foto} source={{ uri: this.props.item.avatar }} />
<Text style={texto}>{this.props.item.displayName}</Text>
<View style={test}>
<Text>{this.props.item.email}</Text>
</View>
</View>
</TouchableHighlight>
</View>
);
}
}
Them change you function to receive the email param.
refresh = (email) => {
let tmp_localData = {};
AsyncStorage.getItem('localData', (err, result) => {
tmp_localData = result;
}).then((result) => {
axios({
method: 'post',
url: 'my Url',
data: {
email: email,
}
})
})
}
And them you can pass the function to component via props
render() {
const { principal, conteudo, imgConteudo1, imgConteudo2, texto, box } =
myStyle;
return (
<View style={principal} >
<BarraNavegacao back navigator={this.props.navigator} tituloProp={this.state.tituloBarraNav} />
<ListaItens callback={this.refresh} />
</View>
);
}

losing my mind - why doesn't my fetch re render (redux)

In my project I have many users and many resources (and many user_resources/the join between users and resources).When I POST to user_resources I see it work on my rails backend (as in I see that instance posted) but in my react native front end I don't see it listed upon update. However, once the app is completely refresh (when I stop and restart the expo server), I finally see those items rendered. ANY IDEAS? I've been working on this forever now to no avail and my project is due tmrw, so any help is appreciated.
screen where I post to user_resources:

}
const mapDispatchToProps = (dispatch) => {

addUserResource,
searchChanged
}
}
export default connect(mapStateToProps,mapDispatchToProps)(ResourcesScreen)
After this I head to the profile page where the user_resources SHOULD be displayed, but aren't
import React from 'react';

}
}
const mapDispatchToProps = {
deleteOneResource
}
const mapStateToProps = (state) => {
return {
users: state.userReducer,
}
}
export default connect(mapStateToProps,mapDispatchToProps)(Profile)
I had a flatlist before but thought that may be causing the issues so rendered it another way, still no luck. I tried forceUpdates as well, still no luck. I'm not sure if the issue is coming from my reducer:
let userInitialState = {
id: 0,
username: "",
name: '',
category: '',
token: "",
user_resources:[],
}
let userReducer = (state = userInitialState, action) => {
switch(action.type){
case "ADD_USERS":
let singleNestedObject = {
...action.users.user,
token: action.users.token
}
return {
...state,
username: action.users.user.username,
token: action.users.token,
id: action.users.user.id,
name: action.users.user.name,
category: action.users.user.category,
user_resources: action.users.user.user_resources
}
case "ADD_ONE_USER_RESOURCE":
let copyOfResources = [...state.user_resources, action.userResources]
return {
...state,
user_resources: copyOfResources
}
default:
return state
}
}
and it's action
export const addUserResource = (resourceInfo) => {
return {
type: "ADD_ONE_USER_RESOURCE",
userResources: resourceInfo
}
}
Please help me find the issue here, I'm losing it.

Why isn't flatlist not able to map through and display the data?

I am using Zomato API to get the list of restaurants, data is in the form of the array which has object restaurants in which there are different restaurant objects and then their name and other details.
It's my first time using a flat List and I am not able to display this data.
Goal: Use the search bar to display the list of restaurants in the city using flatlist.
import React, { Component } from 'react';
import { View, Text } from 'react-native';
import { SearchBar } from 'react-native-elements';
import { FlatList } from 'react-native-gesture-handler';
class Main extends Component {
constructor(props) {
super(props);
this.state = { search: '', data: [] };
}
componentDidMount() {
fetch('https://developers.zomato.com/api/v2.1/search', {
method: 'GET',
headers: {
'user-key': '999999999999999999999999999'
},
params: JSON.stringify({
entity_type: 'city',
q: {this.state.search}
}),
}).then((response) => response.json())
.then((responseJson) => { return this.setState({ data: responseJson.restaurants }) })
.catch((error) => { console.warn(error) }
);
}
render() {
let data = this.state.data;
let name = data.map(p => p.restaurant.name)
console.warn("Check Data", name)
return (
<View>
<SearchBar
round
searchIcon={{ size: 24 }}
placeholder='Search'
onChangeText={search => { this.setState({ search }) }}
value={this.state.search}
/>
//Using this method to display the data if any
{name.length != 0 ?
<FlatList
data={name}
keyExtractor={(x, i) => x + i}
renderItem={({ name }) => <Text>{name}-DATA</Text>}
/>
: <View style={{height:"100%", width:"100%", alignItems:"center",
justifyContent:"center"}}>
<Text>No data found</Text>
</View>
}
</View>
);
}
}
export default Main;
Maybe the way I declared state is wrong, or maybe the way I'm storing the data in the state is wrong.
I got the names of the restaurant in the console.warn successfully.
Without your users-key I can't surely understand what is your api results.
Here
import React, { Component } from 'react';
import { View, Text } from 'react-native';
import { SearchBar } from 'react-native-elements';
import { FlatList } from 'react-native-gesture-handler';
class Main extends Component {
constructor(props) {
super(props);
this.state = { search: '', data: [] };
}
componentDidMount() {
fetch('http://phplaravel-325095-1114213.cloudwaysapps.com/api/shop/shop/', {
method: 'GET',
}).then((response) => response.json())
.then((responseJson) => { return this.setState({ data: responseJson }) })
.catch((error) => { alert(error) }
);
}
render() {
let data = this.state.data;
return (
<View>
<SearchBar
round
searchIcon={{ size: 24 }}
placeholder='Search'
onChangeText={search => { this.setState({ search }) }}
value={this.state.search}
/>
{data.length != 0 ?
<FlatList
data={data}
keyExtractor={(x, i) => x + i}
renderItem={({ item }) => <Text>{item.name}-DATA</Text>}
/>
: <View style={{height:"100%", width:"100%", alignItems:"center",
justifyContent:"center"}}>
<Text>No data found</Text>
</View>
}
</View>
);
}
}
export default Main;
This is a working code with another api call just add your api call instead on mine.. This is working properly. I guess you are just messing with your data.
Try replacing the renderItem from FlatList to
renderItem={({ item }) => <Text>{item}-DATA</Text>}
Also, replace the condition to use double equals like name.length !== 0
Check the url link properly.
https://developers.zomato.com/api/v2.1/search/999999999999999999999999999
Just check it on web browser it is showing message : The requested url was not found
It means we are not getting any data from this URL.
That why we are not able to map any data.

Lodash debounce not working all of a sudden?

I'm using a component I wrote for one app, in a newer app. The code is like 99% identical between the first app, which is working, and the second app. Everything is fine except that debounce is not activating in the new app. What am I doing wrong?
// #flow
import type { Location } from "../redux/reducers/locationReducer";
import * as React from "react";
import { Text, TextInput, View, TouchableOpacity } from "react-native";
import { Input } from "react-native-elements";
import { GoogleMapsApiKey } from "../../.secrets";
import _, { debounce } from "lodash";
import { connect } from "react-redux";
import { setCurrentRegion } from "../redux/actions/locationActions";
export class AutoFillMapSearch extends React.Component<Props, State> {
textInput: ?TextInput;
state: State = {
address: "",
addressPredictions: [],
showPredictions: false
};
async handleAddressChange() {
console.log("handleAddressChange");
const url = `https://maps.googleapis.com/maps/api/place/autocomplete/json?key=${GoogleMapsApiKey}&input=${this.state.address}`;
try {
const result = await fetch(url);
const json = await result.json();
if (json.error_message) throw Error(json.error_message);
this.setState({
addressPredictions: json.predictions,
showPredictions: true
});
// debugger;
} catch (err) {
console.warn(err);
}
}
onChangeText = async (address: string) => {
await this.setState({ address });
console.log("onChangeText");
debounce(this.handleAddressChange.bind(this), 800); // console.log(debounce) confirms that the function is importing correctly.
};
render() {
const predictions = this.state.addressPredictions.map(prediction => (
<TouchableOpacity
style={styles.prediction}
key={prediction.id}
onPress={() => {
this.props.beforeOnPress();
this.onPredictionSelect(prediction);
}}
>
<Text style={text.prediction}>{prediction.description}</Text>
</TouchableOpacity>
));
return (
<View>
<TextInput
ref={ref => (this.textInput = ref)}
onChangeText={this.onChangeText}
value={this.state.address}
style={[styles.input, this.props.style]}
placeholder={"Search"}
autoCorrect={false}
clearButtonMode={"while-editing"}
onBlur={() => {
this.setState({ showPredictions: false });
}}
/>
{this.state.showPredictions && (
<View style={styles.predictionsContainer}>{predictions}</View>
)}
</View>
);
}
}
export default connect(
null,
{ setCurrentRegion }
)(AutoFillMapSearch);
I noticed that the difference in the code was that the older app called handleAddressChange as a second argument to setState. Flow was complaining about this in the new app so I thought async/awaiting setState would work the same way.
So changing it to this works fine (with no flow complaints for some reason. maybe because I've since installed flow-typed lodash. God I love flow-typed!):
onChangeText = async (address: string) => {
this.setState(
{ address },
_.debounce(this.handleAddressChange.bind(this), 800)
);
};

react native modal not close after setState false

I have set modal visibility to false but it still showing. I cant figure out what causes this issue. this my code at loading.js.
I'm use this component in main what happen when setState false but its just close after close simolator and restart the device
import React,{Component} from 'react';

</View>
<Loader
modalVisible={loadingVisible}
animationType="fade"
/>
</KeyboardAwareScrollView>
);
}
}
onsubmitdata setState true and after response going to 200 Setstate set false in code main
You cannot just call state name as you have did. You should do like below.
<Loader
modalVisible={this.state.loadingVisible}
animationType="fade"
/>

Why isn't mailchimp API working with fetch?

I'm trying to add an email address to a mailchimp list I have.
This is for a react native app and I'm trying to implement the request using fetch.
This is my code within the component:
import React, { Component } from 'react';
import { View, Text } from 'react-native';
import { connect } from 'react-redux';
import { emailChanged, nameChanged, addToWaitingList } from '../actions';
import { Card, CardSection, Input, Button, Spinner } from '../components/Auth';
class addToWaitingListForm extends Component {
onEmailChange(text) {
this.props.emailChanged(text);
}
onButtonPress() {
const { email } = this.props;
this.props.addToWaitingList({ email });
}
renderButton() {
if (this.props.loading) {
return <Spinner size="large" />;
}
return (
<Button onPress={this.onButtonPress.bind(this)}>
Keep me in the loop!
</Button>
);
}
render() {
return (
<View>
<Card>
<CardSection>
<Input
placeholder="your name"
onChangeText={this.onNameChange.bind(this)}
value={this.props.name}
/>
</CardSection>
<CardSection>
<Input
placeholder="email#uni.ac.uk"
onChangeText={this.onEmailChange.bind(this)}
value={this.props.email}
/>
</CardSection>
<Text style={styles.errorTextStyle}>
{this.props.error}
</Text>
<CardSection style={{ borderBottomWidth: 0 }}>
{this.renderButton()}
</CardSection>
</Card>
</View>
);
}
}
const mapStateToProps = ({ auth }) => {
const { email, name, error, loading } = auth;
return { email, name, error, loading };
};
export default connect(mapStateToProps, {
emailChanged,
addToWaitingList
})(addToWaitingListForm);
Add this is my action code for interacting with the mailchimp api:
import Router from '../../navigation/Router';
import { getNavigationContext } from '../../navigation/NavigationContext';
export const addToWaitingList = ({ email }) => {
const emailListID = 'e100c8fe03';
fetch(`https://us13.api.mailchimp.com/3.0/lists/${emailListID}/members/`, {
method: 'POST',
body: JSON.stringify({
'email_address': email,
'status': 'subscribed',
'merge_fields': {
'FNAME': 'Urist',
'LNAME': 'McVankab'
}
})
})
.then(() => addSubscriberSuccess())
.catch(error => console.log(error));
};
const addSubscriberSuccess = () => {
getNavigationContext().getNavigator('root').immediatelyResetStack([Router.getRoute('auth')]);
};
Right now, the error I'm just getting back is ExceptionsManager.js:62 Cannot read property 'type' of undefined and Error: unsupported BodyInit type
What does this mean and how can I fix this?
You need to do two things.
First off you need to send the basic authentication via fetch so you cant do "user:pass" You have to convert it with btoa('user:pass').
Then you have to send it with mode: 'no-cors'
let authenticationString = btoa('randomstring:ap-keyxxxxxxx-us9');
authenticationString = "Basic " + authenticationString;
fetch('https://us9.api.mailchimp.com/3.0/lists/111111/members', {
mode: 'no-cors',
method: 'POST',
headers: {
'authorization': authenticationString,
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify({
email_address: "dude#gmail.com",
status: "subscribed",
})
}).then(function(e){
console.log("fetch finished")
}).catch(function(e){
console.log("fetch error");
})
