Delete checked items Rails - ruby-on-rails

Question

I have array selected_ids[] with items id from form, and see them in console when click on the button, but can't delete them in action.
My form:
<% for task in #tasks.where(active: true) %>
<li class="task">
<%= check_box_tag 'selected_ids[]', task.id, false, class: 'selectable' %>
<%= link_to task.title, task, class: "task-title text-dark" %>
</li>
<% end %>
</ul>
My action:
def delete_all
Task.where(id: params[:selected_ids]).destroy_all
#tasks = Task.where(user_id: current_user)
render "index"
end
My routes:
resources :tasks do
get :delete_all, on: :collection
end
Console, when click button:

Answer 1

You have a before_action called set_task in your controller. This is code that will run before delete_all. If you don't want it to run for delete_all, add , except: [:delete_all] to the before_action line:
example:
# change this line somewhere near the top of your controller
before_action :set_task, except: [:delete_all]
If the before_action is set somewhere else like ApplicationController, you can add this line to TasksController instead instead for the same effect:
skip_before_action :set_task, only: [:delete_all]
