How to ensure sending ajax request happen after mouseevents?
I track mouse movement on several elements on an HTML page. I used this [question][1] for the mouse movement function. Then I send how much a user spent over an element using an ajax POST request to a Django view which save it into the db every time there is a new movement. Now I am able to do that, except I noticed that every now and then one of the elements store the time stamp rather than how many seconds. it seems that js is messing up the calculation here: mouseoverTime = currentTime.getTime() - mouseenterTime; it seems that mouseenterTime doesn't get updated with the mouseenter event and remains zero, hence mouseoverTime becomes currentTime.getTime() I am confused because this doesn't happen all the time and I am not getting any errors. could that be because of a problem when the page is loaded? or do I need to put the mouseenterTime variable inside the function? here is my js code: d3.select(window).on('load', function () { let mouseenterTime = 0; $(document).on('mouseenter mouseleave', '#gender_question', function (evt) { let currentTime = new Date(); if (evt.type === 'mouseenter') { mouseenterTime = currentTime.getTime(); } else if (evt.type === 'mouseleave') { mouseoverTime = currentTime.getTime() - mouseenterTime; $.ajax({ … -

Why is my custom django-admin command not running on Heroku?

Django: How to create a mixin to set common attributes for every model?
I have a model mixin that sets created_at, created_by, updated_at and updated_by which I then inherit to most of the models in my project. This model mixin works fine. Obviously setting created_at and modified_at is very easy due to auto_now_add and auto_now. class Timestampable(models.Model): created_at = models.DateTimeField( auto_now_add=True, db_index=True, verbose_name=_('created at') ) created_by = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, related_name="created%(app_label)s_%(class)s_related", on_delete=models.SET_NULL) updated_at = models.DateTimeField( auto_now=True, db_index=True, verbose_name=_('updated at') ) updated_by = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, related_name="updated%(app_label)s_%(class)s_related", on_delete=models.SET_NULL) class Meta: abstract = True ordering = ['-created_at'] But, what I want is to also create a mixin (or maybe subclass) CreateView and UpdateView to set created_by and updated_by to be self.request.user everywhere those CBVs are used ( I would guess by modifying get_form() or form_valid()). I'll also need to create a similar admin mixin to modify save_model(). I have never created a custom mixin and the things I have found/tried aren't working. For example I got subclassing CreateView working by modifying get_form() but then, I couldn't further modify get_form() in the various class ModelXCreate(...) views I created. Does anybody know how I can achieve this? It'd be super useful to be able to have such a mixin and keep things DRY. -
