Redux not passing state to props
I connected a component to the store in a way that it's able to dispatch actions and receive state. The dispatch works and I can see the state change in the Redux dev tool. However, I'm unable to pass the state back to the component. What am I missing here?
Component
The toggle() and addTask() are successfully dispatched. However, the newTask doesn't receive the state.
class AddTask extends React.Component {
state = {
value: '',
};
setValue = value => this.setState({ value });
handleInput = () => !this.props.newTask ? 'hidden' : '';
handleToggle = () => this.props.toggle();
handleSubmit = (e) => {
e.preventDefault();
const title = this.state.value;
this.props.addTask(title);
this.props.toggle();
};
render() {
return (
<div className="add-task">
<div className="btn-add-task">
<Button
type="LINK"
label="Add a Task"
onClick={this.handleToggle}
/>
</div>
<form
className={`task-input ${this.handleInput()}`}
onSubmit={this.handleSubmit}
>
<InputField
placeholder="Task title"
value={value => this.setValue(value)}
/>
</form>
</div>
);
}
};
export default AddTask;
Container
import { bindActionCreators } from 'redux';
import { connect } from 'react-redux';
import AddTask from './TaskList/AddTask/AddTask';
import * as actionCreators from '../actions/taskActions';
const mapStateToProps = state => ({
newTask: state.newTask,
});
const mapDispatchToProps = dispatch => (
bindActionCreators(actionCreators, dispatch)
);
export default connect(
mapStateToProps,
mapDispatchToProps,
)(AddTask);
Reducer
import {
TOGGLE_TASK,
} from '../constants/actions';
const uiReducer = (state = {
newTask: false,
}, action) => {
switch (action.type) {
case TOGGLE_TASK:
return {
...state,
newTask: !state.newTask,
};
default:
return state;
}
};
export default uiReducer;
Store
const initialState = {
tasks: [
{
title: 'Title A', description: 'Description A', effort: '12 hrs', editing: 'false',
},
{
title: 'Title B', description: 'Description B', effort: '24 hrs', editing: 'false',
},
{
title: 'Title C', description: 'Description C', effort: '', editing: 'false',
},
],
ui: {
newTask: false,
},
};
tasks: Array(4)
0: {title: "Title A", description: "Description A", effort: "12 hrs", editing: "false"}
1: {title: "Title B", description: "Description B", effort: "24 hrs", editing: "false"}
2: {title: "Title C", description: "Description C", effort: "", editing: "false"}
3: {id: "", title: "asdfasd", description: undefined}
length: 4
__proto__: Array(0)
ui:
newTask: false
Thanks!

Could you post how your reducer looks like? There might be something wrong with it. Thanks :)

First thing, are you using the container and not the component in your app. Second thing if you use combineReducers in your app, state.newTask might not be the correct value you are trying to access. It would instead be nested inside another object which is the name of your reducer

@devDesigner you should use newTask likeconst mapStateToProps = state => ({ newTask: state.ui.newTask, });
