How do I display an error message with Foundation 5's Abide HTML5 form validation library when no checkboxes are checked within the same checkbox group?
You have to write your own abide validator, but it is quite simple.
Working example: CodePen link
JavaScript
$(document).foundation({
abide: {
validators: {
checkbox_limit: function(el, required, parent) {
var group = parent.closest('.checkbox-group');
var min = group.attr('data-abide-validator-min');
var checked = group.find(':checked').length;
if (checked >= min) {
group.find('small.error').hide();
return true;
} else {
group.find('small.error').css({
display: 'block'
});
return false;
}
}
}
}
});
HTML
<form data-abide>
<div class="row">
<div class="small-12 column">
<h4>Select your favourite vehicles</h4>
</div>
</div>
<div class="row">
<div class="small-12 columns checkbox-group" data-abide-validator-min="1">

I'm following an outdate django e-commerce course using django and stripe. The course is about 4 years old so a lot has changed with django and stripe, which has allowed me to do a ton of research on both. I'm at the end of the tutorial and have run into an issue while creating the checkout page and more importantly using stripe to 'Create Charge'. I am receiving the following error message:
django.utils.datastructures.MultiValueDictKeyError
django.utils.datastructures.MultiValueDictKeyError: 'stripeToken'
I read in the documentation for Creating Charge which states
token = request.POST['stripeToken'] # Using Flask
is for Flask (I think), however when i remove ['stripeToken'], I receive this error message:
stripe.error.InvalidRequestError stripe.error.InvalidRequestError:
Request req_kikB88HKbEkq9W: Could not find payment information
I need a way to pass Stripe the payment information when the form is submitted. Also, I came across this post but the publisher was receiving error message do to multiple forms

I have two models in Ember where one is a collection and the other is book. Collection model has a "hasMany" relationship with "book" and "book" "belongsTo" "collection". So what i want to do is have a form with both models in and store them at the same time.
Collection Model
// collection Model
export default DS.Model.extend({
name: DS.attr('string'),
city: DS.attr('string'),
books: DS.hasMany('book', { async: true })
});
The book model
//book Model
export default DS.Model.extend({
title: DS.attr('string'),
description: DS.attr('string'),
collection: DS.belongsTo('collection', {async: true})
});
The form
//Collection View

<button {{action 'addCollection'}} class="btn btn-primary">New Collection</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
The controller:
actions:{
addCollection: function(){
var name = this.get('collection.name');
var city = this.get('collection.city');
var title1 = this.get('book.title1');
var description1 = this.get('book.description1');
var title2 = this.get('book.title2');
var description2 = this.get('book.description2');
var newCollection = this.store.createRecord('collection', {
name: name,
city: city,
});
},
As you can see I'm trying to obtain 2 sets of books for this collection, but I'm having trouble on finding the correct procedure to store items to these models. I guess I may have to store the collection model first and then push the individual books to the collection. Is this correct? How would I go about it?
If the book is a record already you can simply push it onto the new collection. You don't don't need to assign anything to variables since your template is already bound to the record.
As an improvement I'd suggest creating the collection before the add as well. Either within your model, or on controller initiation.
So the action could be as simple as this.
actions:{
addCollection: function(){
// newCollection and Book need to be records
this.get("newCollection").pushObject(this.get('book'));
},
}
Note: the createRecord will not persist until you call .save() but you do not need to call .save() to create a relationship.
Forgive me for not noticing the multiple new books, here is a more pertinent example.

Notice I've used the model to create the records before hand and it's being passed into the action. You still may need to save for these changes to persist.

I have encounter the same problem too and I don't know why regex seems not working in my Angular 4 project. I start using Validators in Angular's FormGroup and the email validation works like a charm in my project.
Here's my snippet of code for my Edit Profile Page (edit-profile.component.html):
<form [formGroup]="editProfileForm" class="form-horizontal" (ngSubmit)="EditProfile()" >
<div class="form-group">
<label for="email" class="col-md-4 control-label">E-Mail Address </label>
<div class="col-md-6">
<input id="email" type="email" class="form-control" formControlName="email" [(ngModel)]="user.email" required autofocus >
</div>
</div>
<span class="help-block">
<strong>{{ errors.email }}</strong>
</span>
<div class="form-group">
<div class="col-md-6 col-md-offset-4">
<button type="submit" class="btn btn-primary" [disabled]="editProfileForm.pristine">
Update
</button>
</div>
</div>
</form>
and in the edit-profile.component.ts file:
import { NgForm, FormGroup, FormBuilder, FormArray, FormControl, Validators } from '#angular/forms';
private errors = {
email: '',
};
public editProfileForm: FormGroup;
constructor(
private fb: FormBuilder,
) {
this.createForm();
}
createForm() {
// constructor + form Validator
this.editProfileForm = this.fb.group({
email: ['', Validators.compose([Validators.required, Validators.email])],
});
}
EditProfile() {
if (this.editProfileForm.invalid) {
if (this.editProfileForm.controls['email'].hasError('required')) {
this.errors.email = 'E-mail name cannot be empty';
} else if (this.editProfileForm.controls['email'].hasError('email')) {
this.errors.email = 'E-mail is not valid';
}
} else {
// submit the form
}
}
Hope this helps!
Angular 4 has a built-in email validation tag that can be added within the input. E.g.:
<input type="email" id="contactemail" email>
This will be valid for a series of numbers and letters then an # then
another series of letters. It will not account for the dot after the #
-- for that you can use the "pattern" tag within the input and your standard regex.
Or if you want to go with pattern try this
<input type="text" name="email" pattern="^\w+([\.-]?\w+)*#\w+([\.-]?\w+)*(\.\w{2,3})+$" required email/>
To understand/learn RegExp : https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/RegExp
The following should work:
emailPattern:any = new RegExp(/^(([^<>()\[\]\\.,;:\s#']+(\.[^<>()\[\]\\.,;:\s#']+)*)|('.+'))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/);
Let’s say if you have two fields in same row and one requires validation but other not when you trigger validation it shows validation error for other field too. For example, Below is my validation only on “Logged by name” but when I submit the form it throws for “Manager” field too. As soon as I enter something in “Logged by name” field it gets OK.
Here is my HTML,
<div id="Section_ObserverDetails">
<div class="col-sm-12">
<div class="row">
<div class="panel-body form-horizontal">
<div class="form-group">
<div class="col-sm-2">
<label for="pro_LoggedByName" class="col-sm-12 control-label">Logged by name</label>
</div>
<div class="col-sm-4">
<input type="text" class="form-control" id="pro_LoggedByName" name="pro_LoggedByName" value="" > </div>
<div class="col-sm-2">
<label for="top_Manager" class="col-sm-12 control-label">Manager</label>
</div>
<div class="col-sm-4" id="div-top-manager">
<div class="radio">
<label class="form-radio form-normal form-text form-success "><input type="radio" name="top_Manager" value="Yes">Yes</label><label class="form-radio form-normal form-text form-success active"><input type="radio" name="top_Manager" checked="checked" value="No">No</label>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
If I put class="form-group" tag for both the fields then problem gets resolve but "Manager" field slides down to the next row which I don't want.
Any idea ?
In your validation script code, set custom error selector e.g row: '.col-sm-4', so it will override the default error class .has-error .form-control and only target the selector which contains the required input field.
fields: {
pro_LoggedByName: {
row: '.col-sm-4', //<----This is custom error selector
validators: {
notEmpty: {
message: 'The city is required'
}
}
}
}
