Move taxons and taxonomies from spree_backend to OFN

[luisramos0]

What? Why?

Part of #4050

This moves all things related to taxonomies and taxons from spree_backend to OFN. No change in functionality.

What should we test?

The pages must work correctly as before.
Taxonomies: create taxonomy, sort taxonomies. Edit taxonomy: (use right click) add, rename, remove and edit Taxons.
Existing issues:

• cannot delete taxonomy even if newly created if more than one level of taxons.
• cannot sort taxons inside taxonomy Taxonomies - Sorting entries in a taxonomy is broken #2944

Release notes

Changelog Category: Changed

Imported views from spree_backend to make OFN more independent of Spree.

There's quite a few Codeclimate issues. Do you want to handle them separately?

[luisramos0]

this is spree code, these are the not easy ones (complexity, etc). I dont want to fix all of them, a lot of work...

[luisramos0]

moving to test ready.

[RachL]

@luisramos0 code climate is complaining. Can I still test it?

[luisramos0]

yes @RachL I dont think we need to fix all issues in the spree code.

[RachL]

@luisramos0 I wonder : how can I actually create a taxonomy? I would need to drag it above "products" which is our main taxonomy, right?

[luisramos0]

you use the button "new taxonomy"

[RachL]

@luisramos0 🤦‍♀️ I was looking at the edit taxonomy page, so sorry.

Taxonomies:CRUD is working. Sorting is working in the UI, but not in the product category list
Taxons : add and edit is working.

I believe we will need another issue for sorting taxonomies. But this is pre-existing so it is ready to go!

[luisramos0]

thank you!
there's an issue already for the sorting problem: #2944

[RachL]

@luisramos0 this issues covers the sorting within a taxonomy so the sorting of taxons. But I tested as well the sorting of taxonomies. And nothing happened on the categories dropdown when creating a product for example. But I guess for now sorting taxonomies is less prioritary.

[luisramos0]

yeah, and is the order of taxonomies used anywhere now? I mean, the product categories are not taxonomies, they are taxons inside the Product Categories taxonomy.

[RachL]

🤕 yeah it's really weird. I guess users should not be able to select them as categories. But I remember there is already a discussion somewhere on discourse about that.

[luisramos0]

I dont think I understand what is weird. We have a taxonomies system and we use one of the taxonomies as product categories. What's the confusion?

[sigmundpetersen]

In 'New Product' you can choose the taxonomy as one of the categories, e.g. 'Products', 'Others'. I guess that's the weird thing you mention, no @RachL ? They're sorted alphabetically among the other taxons/categories

[luisramos0]

ah, my mistake, all taxonomies and all taxons are shown on the product categories list. I think only taxons inside the Products taxonomy should be shown. But that's not the case now.
