reducer isn't triggered (redux-promise with axios) - reactjs

Question

I'm trying to make an api call in action with axios and pass the results of it to the reducer.
Though action is triggered, reducer isn't. And I can't understand why.
Here's the component that should make api call before mounting
import React, { Component } from 'react';
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux';
//actions
import { getPost } from '../actions/';
class PostShow extends Component {
constructor(props) {
super(props);
}
componentWillMount() {
getPost(this.props.params.id);
}
render() {
console.log(this.props.activePost);
return (
<div>
<h1> hello from a post</h1>
</div>
)
}
}
const mapStateToProps = (state) => {
return {
activePost: state.posts.activePost
}
};
const mapDispatchToProps = (dispatch) => {
return bindActionCreators({
getPost
}, dispatch);
};
export default connect(mapStateToProps, mapDispatchToProps)(PostShow);
Here's my action
import axios from 'axios';
import { FETCH_POSTS, SEND_POST, FETCH_POST } from './types';
const ROOT_URL = 'http://reduxblog.herokuapp.com/api';
const API_KEY = '?key=qwerty';
export function fetchPosts() {
const req = axios.get(`${ROOT_URL}/posts${API_KEY}`);
return {
type: FETCH_POSTS,
payload: req
}
}
export function sendPost(props) {
const req = axios.post(`${ROOT_URL}/posts${API_KEY}`, props);
return {
type: SEND_POST,
payload: req
}
}
export function getPost(id) {
console.log('action triggered');
const req = axios.get(`${ROOT_URL}/posts/${id}${API_KEY}`);
return {
type: FETCH_POST,
payload: req
}
}
And here's my reducer
import { FETCH_POSTS, FETCH_POST } from '../actions/types';
const INITIAL_STATE = {
allPosts: [],
activePost: null
};
export default (state = INITIAL_STATE, action) => {
switch (action.type) {
case FETCH_POSTS:
return {
...state,
allPosts: action.payload.data
};
case FETCH_POST:
console.log('reducer triggered');
return {
...state,
activePost: action.payload.data
};
default:
return state;
}
}
As a result I see 'action triggered' coming from console.log in action, and null coming from console.log in component, and no console.log from the reducer, so it's not triggered and I have no data to render in my component.
Though I make a request and get a response from server with the data, it doesn't go to the reducer. (moreover case FETCH_POSTS works fine and I can render a list of posts, but not a particular one).

You need to use this.props.getPost in componentDidMount instead of getPost.
Connect sends bound action creator to component as a prop
