I want to be able to delete pictures from my model attached to it.
I'm following the answer of this question https://stackoverflow.com/a/49517939/7295677
Here is my view :
<% @vente.image_vente.each do |image| %>
<tr>
<th><%= image_tag(url_for(image), width: "150", height: "100") %></th>
<th><%= link_to delete_image_attachment_gestion_vente_url(image.signed_id),class: "has-text-white", method: :delete, data: { confirm: "Voulez-vous vraiment supprimer cette image ?" } do%>
<button class="button is-dark">Supprimer l'image</button>
<% end %>
</th>
</tr>
<% end %>
Here is the method of my controller :
def delete_image_attachment
@image = ActiveStorage::Blob.find_signed(params[:id])
puts "-------------------------------"
@image.purge
puts "-------------------------------"
redirect_to action: "index"
end
And here is my route :
resources :gestion_vente do
member do
delete :delete_image_attachment
end
end
The problem is that nothing get deleted and I got this :
TRANSACTION (0.1ms) begin transaction
↳ app/controllers/gestion_vente_controller.rb:53:in `delete_image_attachment'
ActiveStorage::Attachment Exists? (0.5ms) SELECT 1 AS one FROM "active_storage_attachments" WHERE "active_storage_attachments"."blob_id" = ? LIMIT ? [["blob_id", 66], ["LIMIT", 1]]
↳ app/controllers/gestion_vente_controller.rb:53:in `delete_image_attachment'
TRANSACTION (0.1ms) rollback transaction
↳ app/controllers/gestion_vente_controller.rb:53:in `delete_image_attachment'
I think that it rollback the transaction without error message
Edit :
As Corentin Bourdat said I could use :
ActiveStorage:: Attachment.find(params[:id]).destroy
But it left me with something I didn't understood. In my model I got
has_one_attached :image_principale
has_many_attached :image_vente
I want to only delete an occurence of :image_vente
. The problem is that everytime it first delete my :image_principale
It's probably because by searching by id it doesn't care if the attachement is of :image_vente
or :image_principale
and I don't know how to do it
