You MUST use this template when reporting issues. Please make sure you follow the checklist and fill in all of the information sections below.

---

All versions of django-smart-selects prior to version 1.2.8 are vulnerable to an XSS attack as detailed in issue 171. As a result, all previous versions have been removed from PyPI to prevent users from installing insecure versions. All users are urged to upgrade as soon as possible.

Checklist

^{Put an x in the bracket when you have completed each task, like this: [x]}

• [x] This issue is not about installing previous versions of django-smart-selects older than 1.2.8. I understand that previous versions are insecure and will not receive any support whatsoever.
• [x] I have verified that that issue exists against the master branch of django-smart-selects.
• [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x] I have debugged the issue to the smart_selects app.
• [x] I have reduced the issue to the simplest possible case.
• [x] I have included all relevant sections of models.py, forms.py, and views.py with problems.
• [x] I have used GitHub Flavored Markdown to style all of my posted code.

Steps to reproduce

1. Have installed smart-selects as per instructions
2. When load issue appeared have manually loaded all js files as per issue #214
3. When page loads get InitItem JSON.parse error in bindfeilds.js line 8 similar to issue #227

Models (have been reduced to just important fields)

class Vocation(Audit):
    CAT_CHOICES = (
        ('GENERAL', 'General'),
        ('ELEMENTARY', 'Elementary'),
        ('SECONDARY', 'Secondary'),
        ('PRESCHOOL', 'Preschool'),
        ('DISTRICT', 'District'),
    )

    name = models.CharField(max_length=255)
    category = models.CharField(max_length=255, choices=CAT_CHOICES)

    def __str__(self):
        return self.name

    class Meta:
        verbose_name_plural = "vocations"

class Area(Audit):
    name = models.CharField(max_length=255)
    vocations = models.ManyToManyField(Vocation)

    def __str__(self):
        return self.name

    class Meta:
        verbose_name_plural = "areas"

class Employee(Audit):

    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='employee')
    cell_phone = PhoneNumberField(blank=True, null=True)
    gender = models.CharField(max_length=10, choices=GENDER_CHOICES, blank=True, null=True)
    hired_by = models.CharField(max_length=10, choices=HIRED_CHOICES, blank=True, null=True)
    hire_type = models.CharField(max_length=20, choices=HIRE_TYPE_CHOICES, blank=True, null=True)
    buildings = models.ManyToManyField(Building)
    avatar = models.ImageField(upload_to=avatar_upload_path, blank=True, null=True)
    reviewed_date = models.DateTimeField(blank=True,null=True)

    #TODO get ChainedManytoManyField to work as expected
    position = models.ForeignKey(Vocation, blank=True, null=True)
    area = ChainedManyToManyField(
        Area,
        horizontal=True,
        verbose_name='areas',
        chained_field="position",
        chained_model_field="vocations")

    class Meta:
        verbose_name_plural = "employees"

    def __str__(self):
        return self.full_name

Forms

import datetime

from django import forms
from .models import Employee

class EmployeeForm(forms.ModelForm):

    class Meta:
        model = Employee
        fields =['gender', 'cell_phone','buildings', 'hired_by', 
                         'hire_type', 'position','area']

View

class EmployeeFormView(UpdateView):
    model = Employee
    template_name = 'ironcsd/employee_form.html'
    form_class = EmployeeForm
    success_url = reverse_lazy('profile-home')

    def get_object(self, queryset=None):
        obj, created = Employee.objects.get_or_create(
                    user=self.request.user.id,
                )
        return obj

    def form_valid(self, form):
        object = form.save(commit=False)

        object.reviewed_date = datetime.datetime.now()
        object.activity_user = self.request.user.username
        object.activity_date = datetime.datetime.now()
        object.save()

        return super(EmployeeFormView,self).form_valid(form)

Actual behavior

• As the bindfields.js does not load properly and errors out at fetching the data-value the area field select does not populate when a position/vocation is selected.
• Sometimes at random the bindfields.js loads properly and will load the chained data to the dom. This is completely at random and have not been able to troubleshoot the reason for data getting set as expected.

Expected behavior

• To work as plugin is expected to work.

This is a more complicated use case for this project. I would recommend using django-autocomplete-light for this instead.

Can you copy and paste the Javascript errors from your console here? And any errors from the Django console?

[blag]

And if you can post the JSON from the AJAX request and responses that would also be extremely helpful. Thanks!
