How to extend the Resource form (to add file upload)?

[HatsuMora]

Hi,

Background:
I have a model that I would like to reuse on multiple pages. I implemented an ingredient that has a selector that allows me to choose what model record to use where. And I'd like to manage this model directly from Alchemy, so I decided to use a custom module to use Alchemy as backend admin, (following this guide).

Problem:
I'd like to attach an image so I display the same image around in different places. How should I do this?

I was on the path of using ActiveStorage, but I stumbled upon the implementation of editable_attributes which builds the form based on the columns of the schema.

Is there a "normal" or "easy" way of doing this before I start overriding a lot of code?

Thanks for your time,

There are several ways to enable uploads for your custom model. All are Rails default ways to add attachments to a Rails model.

To make it work in the Alchemy admin you need to overwrite the form partial in your app/views/admin/resource-name/ folder and use Rails' form helpers to add a file field.

In your model you can either use active storage or dragonfly accessors to allow attachments.
