date time pickers in admin pages missing.

The datetime field model elements are now missing the date and time pickers in the admin pages.

Here is one of the models.

class BroadcastNotification(models.Model):
message = models.TextField()
broadcast_on = models.DateTimeField()
sent = models.BooleanField(default=False)

class Meta:
    ordering = ['-broadcast_on']

Here is the admin page for that model.

I suppose I should have labeled it missing pickers

Where should I look?

Here is my base.html

Your title mentions the “admin pages”, but you’re showing a generic template named “base.html”. (The admin doesn’t use your templates unless you’ve done other work to make that happen.)

Please clarify - how is this template involved with this issue?

What does your ModelAdmin class look like?

I have not modified any of the admin pages, only the base.html as shown. Since I have not modified anything else I assumed that something there was the cause. The nav bar is across the whole solution, and the admin pages load under that.

I suppose I can change the design so the admin pages are not loaded under the base.html. I assume base_site.html would be where I do that.

I took extends admin/base.html out of base_site.html but no change

The admin pages will only load within the base.html if you’ve put it in the templates/admin directory.

Get rid of all your templates out of your admin directory and see if the page is loading correctly with the system templates.

I changed the bootstrap code for the nav-bar removing bg-dark and see that the admin pages are overlapped by the nav-bar.
Add-broadcast-notification-Correlator-2-Administration (3)

will fix.

Ok removed all the files from /templates/admin/ and the admin pages load and behave normally, and the date and time pickers have returned.

Now the question is how to get the bootstrap nav-bar back on my pages and let the admin pages remain unchanged?

If I put my old base.html with its nav-bar in another directory such as /myapp/base.html and have all my pages extend that can I freely navigate back and forth? I will try that so just asking.

Your alternative is to examine the html generated by the admin page, identifying all the css and js being used by that page - and then ensuring that your templates, css, and js don’t interfere with any of it.

Ok moved my old base.html to /myapp/base.html and changed my pages to extend that and now I can go to and from admin pages freely, thanks.

However to facilitate inspect I turned off bg-dark in the navbar and found little black boxes on the right side of all my links in the navbar. see attached. could not find any hints in the bootstrap documentation. that should be the last of this thread.
