Plugin carousel as specified in cmsplugin_cascade.bootstrap3.settings.CMSPLUGIN_CASCADE_PLUGINS could not be loaded

[ngn1123]

Thank you for this terrific api.

I'm having trouble activating some of the plugins, particularly the carousel, image, and picture. In my settings.py, if I activate all plugins with:

CMSPLUGIN_CASCADE_PLUGINS = ('cmsplugin_cascade.bootstrap3',)

it throws the error in the title of this post. When I specify specific plugins such as buttons, collapsable, and container, it works, but it doesn't work for carousel, picture, and images.

The setting names have changed.

CMS Cascade

CMS_PLACEHOLDER_CONF = {
'Page Content': {
'plugins': ['BootstrapContainerPlugin'],
},
}

CMS_CASCADE_PLUGINS = ('cmsplugin_cascade.bootstrap3', )

CMS_CASCADE_LEAF_PLUGINS = (
'TextPlugin',
'PicturePlugin',
'LinkPlugin',
'StylePlugin',
'FormBuilderPlugin',
'FilePlugin',
'VideoPlugin',
'VimeoVideoPlugin',
'TabHeaderPlugin',
'AccordionHeaderPlugin',
'RepositoryDashboardPlugin',
'SessionDashboardPlugin',
'CMSLatestNewsPlugin',
)

In case of trouble, please always refer to the reference implementation. I always use it to test against, in case one of my customers runs into a problem.

[MelvinDRM]

I'm new in this matter of Django and Django CMS and I have the same error, what do you mean with "refer to the reference implementation", or what could be the cause of this?

Thanks in advance

[jrief]

With "refer to the reference implementation" I mean to start with the example project.
Everything you need for it, should be here:
http://djangocms-cascade.readthedocs.org/en/latest/impatient.html

[MelvinDRM]

Ah, I see the problem (I think)..

I changed in bootstrap3.settings I changed CASCADE_PLUGIN for CMSPLUGIN_CASCADE_PLUGIN (which is what the error says) and then when I tried to run it, it gave the error django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.

According to what I've found, AppRegistryNotReady is something introduced in django 1.7, therefore the problem is that this is not made for Django 1.7.x, which is what I'm using for my project.

Anytime soon releasing a version 1.7 compatible?

[jrief]

Hmm, I was able to run it with django-1.7.
Wait, I'll retry.

[jrief]

I just tried with 1.7.3 and it works just as with 1.6.8.
There is a minor issue with django-select2 and django-1.7, therefore don't mix those, but for everything else it works fine.
Make sure to use django-cms 3.0.9

[MelvinDRM]

I'll check it out, thank you!

[MelvinDRM]

I made a clean install and using the link you gave me it works.

If I make a install using Django 1.7.3 and not using django_select2 it gives me the following warning:

---

System check identified some issues:

WARNINGS:
?: (1_6.W001) Some project unittests may not execute as expected.

HINT: Django 1.6 introduced a new default test runner. It looks like this project was generated using Django 1.5 or earlier. You should ensure your tests are all running & behaving as expected. See https://docs.djangoproject.com/en/dev/releases/1.6/#new-test-runner for more information.

If I install it like I want it, it gives me the same "django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet" error.

I place my requirements and my settings.py just in case:

[harry81]

The below error message took me here.

django.core.exceptions.ImproperlyConfigured: Plugin carousel as specified in cmsplugin_cascade.bootstrap3.settings.CMSPLUGIN_CASCADE_PLUGINS could not be loaded

And I found that this is because of the "filer.fields.image."

ipdb> from cmsplugin_cascade.bootstrap3 import carousel
*** ImportError: No module named filer.fields.image

Just installing "django-file" package solved the problem in my case.

pip install django-file

[jrief]

Sorry about that.
The next version will have better error handling support, for these kinds of import errors.

[rfleschenberg]

Should django-filer be declared as a dependency anywhere?

[jrief]

Yes, for everything using the Image class.

[rfleschenberg]

I am closing this, even though my opinion still is that we should declare dependencies in setup.py. But we can discuss this in another issue, maybe.
