Django CMS:: Deserialization Error :: page has no field named 'path'

Question

I have a Django application which is using Django CMS. I had built custom plugins, pages, users etc. in the application using CMS. I want to export the CMS data from my application to another instance of the same application which doesn't have any cms related data.

I am using the following command:

python manage.py dumpdata cms djangocms_column djangocms_file djangocms_googlemap djangocms_link djangocms_picture djangocms_style  djangocms_text_ckeditor djangocms_video > cms_export.json --indent=2

I copied that file to the other app instance and tried to load it using the following command:

python manage.py loaddata cms_export.json

I got the following error:

django.core.serializers.base.DeserializationError: Problem installing fixture '/cms_export.json': Page has no field named 'path'

cms_export.json snippet:

Thanks in advance.

Answer 1

Your error is claiming that cms.page does not have a 'path' field, which could mean the model may not have the schema that you expect it to.
