Django TinyMCE external_image_list_url breaking admin urls

[Chris Davies-Barnard]

Hi all,

I posted this on SO but have not had any interest and I'm still stuck so would really really appreciate someone taking a look.

I have a pages app into which I have implemented TinyMCE for the main content. This works and I am able to format content and view it on the front end. I'm now trying to add the image list support as per the Django/TinyMCE Docs but have stumbled upon a problem. When I uncomment the mce_attrs line below all my admin urls break not just the page add/edit ones.  It is as if the line breaks my URL files but I cannot figure out why. 

	from tinymce.widgets import TinyMCE
	content = forms.CharField(widget=TinyMCE(
		attrs={ 'cols': 80, 'rows': 30 },
		#mce_attrs={ 'external_image_list_url': reverse('mediamanager.views.imagelist')},
	))

The mediamanager.views.imagelist is set up and working.   I can browse to it as a normal URL and it shows a list of images 

url(r'^tinymce/$', views.imagelist, name='imagelist'),

var tinyMCEImageList = [["(/media/uploads/2015/10/20141205_142735.jpg", "/gallery/i/4"], ... ]

the view itself looks like:

def imagelist(request):
  from tinymce.views import render_to_image_list
  objects = Image.objects.all()
  link_list = [(unicode("/media/" + str(obj.image)), obj.get_absolute_url()) for obj in objects]
  return render_to_image_list(link_list)

Thanks in advance for any advice.

Regards

Chris

Try changing the reverse() call to just reverse('imagelist'). I believe reversing using the full view import path has been deprecated/removed. That, and you named the URL 'imagelist', may as well refer to it by name. ;-)

If that doesn't work, please post the error and entire traceback that you are receiving.

Hi James,

Thanks for the reply.   So I uncommented the line which now looks like: 

mce_attrs={ 'external_image_list_url': reverse('imagelist')},

and after restarting apache I get this.

Page not found (404)

Request Method:	GET
Request URL:	http://csmatrix.local/admin/main/page/add/

Using the URLconf defined in CSMatrix.urls, Django tried these URL patterns, in this order:

1. ^$ [name='cover']
2. ^m/
3. ^curriculum/
4. ^unitsoflearning/
5. ^studyprogramme/
6. ^gallery/
7. ^reprographics/
8. ^accounts/
9. ^login/$
10. ^logout/$
11. ^tinymce/
12. ^admin/doc/
13. ^admin/ ^$ [name='index']
14. ^admin/ ^login/$ [name='login']
15. ^admin/ ^logout/$ [name='logout']
16. ^admin/ ^password_change/$ [name='password_change']
17. ^admin/ ^password_change/done/$ [name='password_change_done']
18. ^admin/ ^jsi18n/$ [name='jsi18n']
19. ^admin/ ^r/(?P<content_type_id>\d+)/(?P<object_id>.+)/$ [name='view_on_site']

The current URL, admin/main/page/add/, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

It makes no difference if I try and run it though runserver or apache - same result.  All my admin urls are broken!   I know this is not much help - is there another way of getting a traceback?

Regards

Chris

Do you have an app named 'main'? Is it part of INSTALLED_APPS? And is the Page model properly registered with the admin site?

How exactly did you reach that URL? Does the admin work if you just use /admin/?

Hi James,

Well,  I seem to have made it work by removing the reverse command all together.   

mce_attrs={ 'external_image_list_url': 'http://csmatrix.local/gallery/imagelist/'},

obviously this is not a very elegant solution but its working.    I also noted that I could not use tinymce 4 as the image box failed to load period.   I'm also wondering whether I could/should use reverse_lazy because of when this line is being called.

Cheers for your help.   I'd be interested in your thoughts.

Hi James,

Thanks for the response.   I have just replied to say its working in one sense.   Main is my pages, blog and homepage app and then mediamanager is the app that manages images etc uploaded into the media folder.   I can create albums which are inserted using wordpress style shorttags into pages and posts and I can set featured images for both.  It all works very nicely for me except being able to easily insert single images into the middle of pages.

When I went to the main admin page with reverse included it gave a traceback that looked the following.

I would obviously like to get it working correctly but for now will leave it as is and move on.

Thanks for your help.

Chris
