Forest Admin not working with Active Storage

Feature(s) impacted

Forest Admin is not working with every table that I have some active storage relationship. For example, this simple code makes the request for data fail. Removing the line makes Forest show all other columns.

class Deposit < ApplicationRecord
  has_one_attached :receipt_image
end

Rails generated schema:

  create_table "active_storage_attachments", id: :uuid, default: -> { "gen_random_uuid()" }, force: :cascade do |t|
    t.string "name", null: false
    t.string "record_type", null: false
    t.uuid "record_id", null: false
    t.datetime "created_at", null: false
    t.uuid "blob_id", default: -> { "gen_random_uuid()" }, null: false
    t.index ["blob_id"], name: "index_active_storage_attachments_on_blob_id"
    t.index ["record_type", "record_id", "name", "blob_id"], name: "index_active_storage_attachments_uniqueness", unique: true
  end

  create_table "active_storage_blobs", id: :uuid, default: -> { "gen_random_uuid()" }, force: :cascade do |t|
    t.string "key", null: false
    t.string "filename", null: false
    t.string "content_type"
    t.text "metadata"
    t.bigint "byte_size", null: false
    t.string "checksum", null: false
    t.datetime "created_at", null: false
    t.index ["key"], name: "index_active_storage_blobs_on_key", unique: true
  end

Observed behavior

Forest Admin always returns a 500 status code and no data.

{ "status": 500, "error":" Internal Server Error" }

Expected behavior

Forest Admin to show my models that have attachments.

I really need your help here guys as one of our main features needs to validate user bank receipts and our non-technical team is having a lot of problems validating these user-uploaded receipts in the dashboard. So far we are using JetAdmin but I like Forest and don’t want to migrate just because of this situation.

Thank you.

Hi @amarildo,

It seems that the service_name field is missing in your active_storage_blobs migration.

The problem occurs in all three environments ?

Can you share the error log ?

Hi @nicolasa thank you for your reply.

Yes, the problem occurs in all my environments including development. And I can reproduce all of them. It is not the service_name.

In this simple example and every other model that has the has_one_attached association, Forest fails to render the views.

class Bank < ApplicationRecord
  has_one_attached :logo # If I comment on this line Forest will work

  def aws_logo_url
    ENV['AMAZON_S3_BASE_URL'].to_s + logo.blob.key if logo.attached?
  end
end

This is the log, they all are similar.

Unfortunately, I am not able to reproduce the problem on my side.

Did you have a specific configuration for has_one_attached?

Can you share the migration of your Bank and Deposit model?

Hi @nicolasa, I haven’t any specific configuration.

Bank Model

class Bank < ApplicationRecord
  has_many :bank_accounts
  has_many :company_bank_accounts
  has_one_attached :logo

  validates :code, presence: true
  validates_format_of :code, with: /\A\d{4}\z/

  scope :list, -> { all.order('name ASC') }

  def aws_logo_url
    ENV['AMAZON_S3_BASE_URL'].to_s + logo.blob.key if logo.attached?
  end
end

Bank Migration

  create_table "banks", id: :uuid, default: -> { "public.gen_random_uuid()" }, force: :cascade do |t|
    t.string "name"
    t.text "description"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string "logo_url"
    t.string "app_link"
    t.string "logo"
    t.string "code"
  end

Thanks.

Hi @nicolasa, thank you for your help.

I was able to find the problem, it was something with Rails to_json method failing to parse the objects.

Thanks.
