Product categories

[Raymond Besiga]

How are product categories implemented in Django Oscar. Going by the example in the sandbox, it does not seem like a straight forward process. I have tried to add product categories or just categories but its not working as expected.

When i try to add a category, i get the following error:

TemplateDoesNotExist at /admin/catalogue/category/

admin/tree_change_list.html

Is there a template in Django Oscar that I am missing or do I have to create it myself. Any advice regarding product categories will be appreciated

You can use the dashboard to add categories.

Ensure you have treebeard in your INSTALLED_APPS for that template to be picked up.  If you use the get_core_apps helper function, this happens automatically.

Hey David,

I added treebeard and was already using the get_core_apps helper function. Running pip install django-treebeard alerts me that the requirement is already satisfied. My traceback is as follows:

Hi Raymond,

I think you're seeing this issue: https://github.com/tangentlabs/django-oscar/issues/761 Can you enable 'django.template.loaders.eggs.Loader' and let me know if it fixes things?

Please test against a current checkout of Oscar's master branch. I was just trying to recreate the issue, and for me the category display is working. Note that this is unsupported and you should use the dashboard.



Cheers,

Maik

Hey Maik,

Thanks so much. This fixed everything. Was having a similar issue! Thanks for saving me lots of time. And for being so helpful.

Hi Raymond,

good to hear it worked. I've made it the default behaviour now:
https://github.com/tangentlabs/django-oscar/commit/e38e8c95f822b11f201e6b020a5dc3f5c8eb9b7e

Have a good week,

Maik
