I am working on a "settings" page where a logged in user can change their profile picture. However it seems that Meteor is having trouble finding the profile attribute for a user.
signup.js (here is where I create the user on signup and create the profile attribute)
import React, { Component } from 'react';
import { browserHistory } from 'react-router';
export default class Signup extends Component {
handleSubmit(event) {
event.preventDefault();
var signupEmail = event.target.signupEmail.value;
var signupPassword = event.target.signupPassword.value;
if (signupPassword !== '') {
Accounts.createUser({
email: signupEmail,
password: signupPassword,
profile: {
avatar: "/user-default.svg"
}
}, (err) => {
err ? (console.log(err.reason)) : browserHistory.push("/app/profile");
});
}
}
render() {
return (
<div className="login-form">
<form onSubmit={this.handleSubmit}>
<div className="input-options">
<input type="text" placeholder="Email" name="signupEmail" />
</div>
<div className="input-options">
<input type="password" placeholder="Password" name="signupPassword" />
</div>
<button className="login-submit bold">Sign me up!</button>
</form>
</div>
);
}
}
profile_settings.js
import React, { Component } from 'react';
import { Link } from 'react-router';
import reactMixin from 'react-mixin';
import ReactMeteorData from 'meteor/react-meteor-data';
export default class ProfileSettings extends Component {
constructor(props) {
super(props);
this.state = {
avatar: this.props.user.profile.avatar
}
}
getMeteorData(){
return{
user: Meteor.user()
}
}
componentWillMount(){
// we create this rule both on client and server
Slingshot.fileRestrictions("avatar", {
allowedFileTypes: ["image/png", "image/jpeg", "image/gif"],
maxSize: 2 * 500 * 500
});
}
upload(){
var userId = Meteor.user()._id;
var metaContext = {avatarId: userId};
var uploader = new Slingshot.Upload("UsersAvatar", metaContext);
uploader.send(document.getElementById('input').files[0], function (error, downloadUrl) { // you can use refs if you like
if (error) {
// Log service detailed response
console.error('Error uploading', uploader.xhr.response);
alert (error); // you may want to fancy this up when you're ready instead of a popup.
}
else {
// we use $set because the user can change their avatar so it overwrites the url :)
Meteor.users.update(Meteor.userId(), {$set: {"profile.avatar": downloadUrl}});
}
// you will need this in the event the user hit the update button because it will remove the avatar url
this.setState({avatar: downloadUrl});
}.bind(this));
}
formSubmit(){
let avatarUrl = this.state.avatar;
Meteor.users.update( {_id: Meteor.userId() }, {

Here is the error I am getting: TypeError: Cannot read property 'profile' of undefined
The error is not failing to find an profile attribute, but says that there's no user (or that user is undefined) This is exactly what TypeError: Cannot read property 'profile' of undefined means.
There are a few errors in your code:
the return of getMeteorData is available under this.data and not this.props
getMeteorData will run after constructor so there's no way to get Meteor's data in the constructor
getMeteorData returns data reactively, and is likely not to have the data you want when you instantiate the class anyway
So I'd recommend using the container/component approach that is like:
export default class ProfileSettingsContainer extends Component {
getMeteorData(){
return{
user: Meteor.user()
}
}
render() {
const user = this.data.user;
if (user) {
return <ProfileSettings user={user} />
} else {
return null; // or what ever placeholder you want while the data is being loaded
}
}
}
class ProfileSettings extends Component {
constructor(props) {
super(props);
this.state = {
avatar: props.user.profile.avatar
}
}
}
with this structure, the ProfileSettings will instantiate with something under props.user
Finnaly,
Meteor.users.update( {_id: Meteor.userId() }, {
$set: {profile: avatarUrl}
});
should be
Meteor.users.update( {_id: Meteor.userId() }, {
$set: {'profile.avatar': avatarUrl}
});
but that's unrelated

I really need help cause I'm totally new to reactjs. How can I maintain the logged-in user throughout the page? like a session. the code shows the data called when I logged in. I'm really lost here in react.
When the credentials are true, here's the result
{userId: 1, firstname: "Jeff", middlename: null, lastname: "Geli", positionId: 1, …}
userId: 1
firstname: "Jeff"
middlename: null
lastname: "Geli"
positionId: 1

You could use sessionStorage or localStorage to store the token and then check for it, if it is set then keep user logged in otherwise logout user.
set the session once user logged in
if (token) {
localStorage.setItem('session', JSON.stringify(token));
}
To check if the user is logged in
let user = localStorage.getItem('session');
if (user) {
console.log('Valid session');
} else {
console.log('Not valid session');
}
On logut clear the value
let user = localStorage.getItem('session');
if (user) {
localStorage.removeItem();
}
Adding the logic in the provided code
async handleSubmit(event) {
// .... Other code
const data = await getCred.json();
if (data.status == 400) {
alert(data);
} else {
this.handleSuccess(data);
}
console.log(data);
}
//Set your token in handleSuccess method
handleSuccess(data) {
alert("Logged IN");
if (data.token) {
localStorage.setItem('session', JSON.stringify(data.token));
}
this.props.history.push('dashboard/v2');

I am working with redux-form and it seems confusing me to load initial data for edit form but the data is not being validated on submit. I have managed to pass and load data into the fields but that seems not loading into the form props etc. Please see the following piece of code and let me know if need something more.

I have a form that should update my applications state as a user types in the input field and in the textarea. The input and textarea call their event handlers through onChange={event handler}. For some reason when I type in either field the event handlers don't get called at all. The input and textarea fields seem to work fine outside of a form though.

I am learning REACT and am having some trouble.
I have multiple pages/components each of these pages has a form in it and I have written a function to handle the form input once submitted.
However i would like to move this function to its own component this way each of the pages simply calls this single component when the form is submitted.
My question is how to do accomplish this using REACT, I have been searching for hours and just cannot figure it out.
Here are two example components:
Form handler/form processing
'use strict';
import React from 'react/addons';
const FormProcessing = React.createClass({
_test: function() {
console.log('test');
//do something with form values here
},
render(){
}
});
export default FormProcessing;
Example component with form, that needs to call the 'test' function from the 'FormProcessing' component
'use strict';
import React from 'react/addons';
import {Link} from 'react-router';
import DocumentTitle from 'react-document-title';
const BreakingNewsPage = React.createClass({
propTypes: {
currentUser: React.PropTypes.object.isRequired
},
_inputFields: function() {
return (
<form id="breakingNewsForm" action="" onclick={call test function from form processing component}>
<fieldset>
<legend>Headline</legend>
<div className="form-group">
<input type="text" className="form-control input-size-md" id="inputHeadline" placeholder="Headline (Example: Budget Cuts)"/>
</div>
<legend>Breaking News</legend>
<div class="form-group">
<input type="text" className="form-control input-size-lg" id="inputDescription1" placeholder="Breaking News Description"/>
<input type="text" className="form-control input-size-lg" id="inputDescription2" placeholder="Breaking News Description"/>
</div>
</fieldset>
</form>
);
},
_formButtons: function() {
return (
<div className="form-buttons">
<button form="breakingNewsForm" type="reset" className="btn-lg">Clear</button>
<button form="breakingNewsForm" type="submit" classn="btn-lg">Save</button>
</div>
);
},
render() {
return (
<DocumentTitle title="Breaking News">
<section className="ticker-page page container-fluid">
<div className="page-title">
<h1>Breaking News</h1>
</div>
<div className="com-md-6">
{this._inputFields()}
{this._formButtons()}
</div>
</section>
</DocumentTitle>
);
}
});
export default BreakingNewsPage;
Updated code using example provided by: ycavatars

This is the FormProcessing class
'use strict';
import React from 'react/addons';
var IntroPage = require ('../pages/IntroPage.js')
class FormProcessing extends React.Component {
_handleForm() {
console.log('you caled me!');
}
};
export default FormProcessing;
You want to invoke FormProcessing._test from BreakingNewsPage component. You have to know the difference between class and instance. React.createClass returns a class which describes your component, and the render method of your component returns a virtual DOM element.
In order to call FormProcessing._test, you have to get the reference to the backing instance of FormProcessing class. That's why react provides a ref. The official tutorial explains the details.
There's an open source project, how to center in css, uses many ref. You could take a look.
Using the example of initializingFromState within Redux-Form, I am trying to set this up dynamically. This is to edit a particular book in a list of books, and is using a simple api set up in express.js.
The full container is below. I somehow need to pass in initialValues, within the mapStateToProps function. In the example, it is done via a static object, but I can't work out how to use the information I have pulled in via fetchBook, and pass it to initialValues.
Container:
import React, { Component, PropTypes } from 'react';
import { reduxForm } from 'redux-form';
import { connect } from 'react-redux';
import { Link } from 'react-router';
import { fetchBook, editBook } from '../actions/index';
class BookEdit extends Component {
componentWillMount() {
this.props.fetchBook(this.props.params.id);
}
static contextTypes = {
router: PropTypes.object
}
onSubmit(props) {
this.props.editBook(this.props.book.id, props)
.then(() => {
this.context.router.push('/');
});
}
const data = {
title: {this.props.book.title},
description: {this.props.author}
}
render() {
const { fields: { title, author }, handleSubmit } = this.props;
const { book } = this.props;
if (!book) {
return (
<div>
<p>Loading...</p>
</div>
)
}
return (
<div>
<Link to="/">Back</Link>
<form onSubmit={handleSubmit(this.onSubmit.bind(this))}>
<h2>Add a new book</h2>
<label>Title</label>
<input type="text" {...title} />
<div className="text-help">{title.touched ? title.error : ''}</div>
<label>Author</label>
<input type="text" {...author} />
<div className="text-help">{author.touched ? author.error : ''}</div>
<button type="submit">Add</button>
<Link to="/" className="button">Go back</Link>
</form>
</div>
);
}
}
function mapStateToProps(state) {
return {
book: state.books.book,
initialValues: // how do I pass in the books here?
};
}
export default reduxForm({
form: 'EditBookForm',
fields: ['title', 'author']
}, mapStateToProps, { fetchBook, editBook })(BookEdit);
Thank you.
Your form values aren't what's in state.books.book? I think this is all you're looking for:
function mapStateToProps(state) {
return {
book: state.books.book,
initialValues: state.books.book
};
}
Since you're only really looking at this.props.book to know if it's loaded or not, it might be more explicit to do something like:
function mapStateToProps(state) {
return {
loaded: !!state.books.book,
initialValues: state.books.book
};
}
Hope that helps.
In related to above question, Erik. I have following form and not sure why it is not Validating on submit. It loads the data into fields but when I hit submit the validation fails.
