Crash when Show user in the Admin dashboard

NG DAVID
I would like to impersonate another user.  When I click on the user on the user list, it crashes with the following message when user has avatar image  with the following message


NameError in Admin::Users#show

Showing /home/david/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/bundler/gems/administrate-66c6d333106b/app/views/fields/has_one/_show.html.erb where line #22 raised:
uninitialized constant AvatarAttachmentDashboard

It is OK if the user does not have avatar.  What is wrong ? 


Same here!

There's another post about this somewhere here. If you just want to get it working comment out all the `Avatar` lines in the `app/dashboards/user_dashboard.rb` file

require "administrate/base_dashboard"

class UserDashboard < Administrate::BaseDashboard

  ATTRIBUTE_TYPES = {
    id: Field::Number,
    ...
    # avatar_attachment: Field::HasOne, # <============= COMMENT THIS OUT
    # avatar_blob: Field::HasOne, # <=================== COMMENT THIS OUT
    ...
  }.freeze

  # SHOW_PAGE_ATTRIBUTES
  # an array of attributes that will be displayed on the model's show page.
  SHOW_PAGE_ATTRIBUTES = [
    :id,
    ...
    # :avatar_attachment, # <======================== COMMENT THIS OUT
    # :avatar_blob, # <============================== COMMENT THIS OUT
    ...
  ].freeze

end

Not had time to look into a proper fix for this yet but I don't care about seeing the user's image in the admin dashboard so I just removed the attributes and left it at that 😀

I just published a fix for this. I've added ActiveStorage support to the admin (using this) so the avatars are now set as activestorage fields. You can also add your own AS fields to the admin easily.
Thanks

Was just looking for this, thanks.
