Setup a dynamic form controlled by the user using react-redux and revalidate to run validation checks on my form.
Since my form is dynamic I need to make dynamic validations. In order to do this my form data needs to be passed in as props to my component, which can be used as a second argument in the validate function from revalidate
To do this I am waiting until the component is mounted, building the form, passing it to redux, and then will map state to props. As the user adds more rows I will update state and then the component will render. I will use shouldComponentUpdate() to avoid any render loops.
My error is regarding the dispatch. When I try to run the dispatch (which will pass the form into redux) I get Dispatch is not a function
error.
I am not supper comfortable with the connect()
as I have to wrap redux with it as well as firebase. This syntax really confuses me.
I believe the issue with with how I am exporting the component where I am using HOC like withFirebase, Redux, and Connect. Somewhere along the way I am losing scope to the connect. Can someone shed light into what it is I am doing wrong?
import React, { Component } from "react";
import { reduxForm, Field } from "redux-form";
import { Container, Form, Col, Button } from "react-bootstrap";
import MaterialIcon from '../../material-icon/materialIcon';
import { withFirestore } from "react-redux-firebase";
import { connect } from "react-redux";
import TextInput from "../../forms/textInput";
import { combineValidators, isRequired } from "revalidate";
import { setupStudentForm } from '../../../store/actions/students';
const validate = (values, ownprops) => {
// Will be passing in validation rules, once form is apssed in with props via mapStateToProps.
}
export class CreateStudentsForm extends Component {
// Using constrcutor so componentDidMount() can render() cann access variables
constructor(props) {
super(props);
this.state = {
rows: 2,
}
this.formArray = [];
this.form = null;
}
componentDidMount() {
// Once component is rendered, setup form and send to redux
for (let i = 1; i !== this.state.rows + 1; i++) {
let firstNameField = {
fieldName: `firstName${i}`,
label: 'First Name',
required: true,
type: "text",
}
let lastNameField = {
fieldName: `lastName${i}`,
label: 'Last Name',
required: true,
type: "text",
}
this.formArray.push([firstNameField, lastNameField]);
}
this.props.setupStudentFormHandler(this.formArray);
}
// Ensure we do not get stuck in render loop
shouldComponentUpdate(nextProps, nextState){
if(nextProps !== this.props){
return true
} else {
return false
}
}
render() {
// Allows user to add another row
const addRow = () => {
this.setState({
rows: this.state.rows + 1
})
}
// Map through form array and create template
if (this.formArray) {
let form = this.formArray.map((field, index) => {
return (
<Form.Row key={index} className="animated fadeIn">
<Col xs={5}>
<Form.Group className="mb-0 noValidate">

label={field[0].label}

})
}
return (

{this.form}
<Button variant="outline-success" onClick={addRow}>Add Another Student</Button>
</Container>
)
}
}
const mapStateToProps = state => {
return {
// Get access to student state which will have form
studentForm: state.students
};
};
const mapDispatchToProps = dispatch => {
return {
//Send formArray to redux
setupStudentFormHandler: (form) => dispatch(setupStudentForm(form))
};
};
export default withFirestore(
reduxForm({
form: "createStudents", validate
})(connect(
mapDispatchToProps,
mapStateToProps
)(CreateStudentsForm)
)
);

mapStateToProps
is the first argument of connect
, mapDispatchToProps
is the second. Try swapping the order:
connect(
mapStateToProps,
mapDispatchToProps
)(CreateStudentsForm)
