Hi guys i have a problem in my code any one can help me with redux-thunk
Action.js
import axios from 'axios';
import { API_URL, API_KEY } from './const';
export const FETCH_FLAG_GENDERS = 'FETCH_FLAG_GENDERS';
export const FETCH_FLAG_COUNTRIES = 'FETCH_FLAG_COUNTRIES';
export const FETCH_FLAG_PROVINCES = 'FETCH_FLAG_PROVINCES';
export const FETCH_FLAG_BLOODGROUPS = 'FETCH_FLAG_BLOODGROUPS';
export const FETCH_FLAG_BLOODGROUPTYPES = 'FETCH_FLAG_BLOODGROUPTYPES';
export function fetchFlagProvinces() {
return async dispatch => {
function onSuccess(request) {
dispatch({
type: FETCH_FLAG_PROVINCES,
payload: request
});
return request;
}
function onError(error) {
console.log(error);
}
try {
const request = axios.get(`${API_URL}/flag/province`, {
headers: { Authorization: API_KEY }
});
return onSuccess(request);
} catch (error) {
return onError(error);
}
}
}
Reducer
import {
FETCH_FLAG_GENDERS,
FETCH_FLAG_PROVINCES,
FETCH_FLAG_COUNTRIES,
FETCH_FLAG_BLOODGROUPS,
FETCH_FLAG_BLOODGROUPTYPES
} from '../actions/flag';
const FLAG_INITIAL_STATE = {
genderList: [],
provinceList: [],
countryList: [],
bloodGroupList: [],
bloodGroupTypeList: []
};
export default function( state = FLAG_INITIAL_STATE, action){
switch(action.type){
case FETCH_FLAG_PROVINCES:
console.log('====REDUCER====')
console.log(action);
return {
...state,
provinceList: action.payload.data
};
break;
default:
return state;
}
}

Container
import React, { Component } from 'react';
import { connect } from 'react-redux';
import { Field, reduxForm } from 'redux-form';
import { fetchFlagGenders, fetchFlagProvinces, fetchFlagCountries, fetchFlagBloodGroups, fetchFlagBloodGroupsType } from '../../actions/flag';
import { Card, Input, FormGroup, TextArea, Row, Column, Select } from '../../component/bootstrap/';
class PatientForm extends Component {
async componentWillMount() {
//this.props.fetchFlagGenders();
//this.props.fetchFlagProvinces();
//this.props.fetchFlagBloodGroups();
//this.props.fetchFlagBloodGroupsType();
//this.props.fetchFlagProvinces();
this.props.fetchFlagProvinces()
.then((response) => {
console.log('====CONTAINER=====');
console.log(response.data);
}, (error) => {
console.log('fail');
});
}
render() {
const { handleSubmit } = this.props;
console.log('===PROP PROVINCE LIST===')
console.log(this.props.provinceList);
console.log('===END PROVINCE LIST===')
return (
<Row>
<Card>
</Card>
</Row>
);
}
}
const validate = (values) => {
const errors = {};
if(!values.firstName)
errors.firstName = 'please enter first name';
if(!values.lastName)
errors.lastName = 'please enter last name';
return errors;
}
const mapStateToProps = (state) => {
return {
genderList: state.flags.genderList,
provinceList: state.flags.provinceList,
bloodGroupList: state.flags.bloodGroupList,
bloodGroupTypeList: state.flags.bloodGroupTypeList
}
}
PatientForm = connect(mapStateToProps, { fetchFlagGenders, fetchFlagProvinces, fetchFlagBloodGroups, fetchFlagBloodGroupsType })(PatientForm);
export default reduxForm({
validate,
'form': 'PatientForm'
})(PatientForm);
Index JS
import 'babel-polyfill';
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import promise from 'redux-promise'
import thunk from 'redux-thunk'
import reducers from './reducers';
import App from './app';
const store = createStore(
reducers,
applyMiddleware(thunk)
);
ReactDOM.render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById('app'));
Oh forget reducer index.js
import { combineReducers } from 'redux';
import { reducer as formReducer } from 'redux-form';
import PatientReducer from './patient_reducer';
import FlagReducer from './flag_reducer';
import ConfigurationReducer from './configuration_reducer';
const rootReducer = combineReducers({
flags: FlagReducer,
patients: PatientReducer,
form: formReducer
});
export default rootReducer;
I have no idea why in container i cannot use this.props.provinceList it said undefined! and also i check from console.log it is promise but it seem like when promise complete it not update the state can anyone help me please .
Here is api url http://demo3918385.mockable.io/flag/province
Note 1: In container this.props.fetchFlagProvinces() is can fetch data properly everythink working ok start with promise end ending with data
And also where the code should i improve please let me know. Thank
You forgot await keyword in front of your axios' request. You get a Promise because you don't wait for it to be processed.
try {
const request = await axios.get(`${API_URL}/flag/province`, {
headers: { Authorization: API_KEY }
});
return onSuccess(request);
} catch (error) {
return onError(error);
}
