Rails 5.2 Remoção / exclusão de anexos do Active Storage
Então, eu estou usando o Active Storage para carregar várias imagens anexadas a um modelo de coleção. Tudo funciona bem, exceto quando estou tentando limpar / excluir um único anexo de uma coleção.
O problema: Por alguma razão, todas as minhas imagens são eliminadas / excluídas imediatamente sempre que carrego a página de apresentação de uma coleção. Claro que só quero excluir um arquivo sempre que clicar no link. Alguém sabe como resolver esse problema?
Minha exibição de exibição de coleção:
<div id="gallery">
<% @collection.images.each do |image| %>
<%= image_tag(image) %>
<%= link_to 'Remove image', image.purge %>
<% end %>
</div>
Eu li a documentação emhttp://edgeguides.rubyonrails.org/active_storage_overview.html#removing-files (ver ponto 4)
mas, infelizmente, isso não fornece nenhuma informação sobre como usar especificamente o método purge ou purge_later.
EDITAR Atualmente mudei meu código para este (que infelizmente ainda não funciona):
<div id="gallery">
<% @collection.images.each do |image| %>
<%= image_tag(image) %>
<%= link_to 'Remove', delete_image_attachment_collections_url(image.signed_id),
method: :delete,
data: { confirm: 'Are you sure?' } %>
<% end %>
</div>
Com isso em minhas coleções_controller.rb
def delete_image_attachment
@image = ActiveStorage::Blob.find_signed(params[:id])
@image.purge
redirect_to root_path
end
O que está causando esse erro depois que tentei excluir uma imagem anexada:
