Problem with deleting multiple users


I’m a beginner with ruby on rails, so I don’t really know what I’m doing

I have a index.html.erb where I list users. Before every user is a
checkbox, which I’d like to use when destroying several users.

I hope someone can help me :slight_smile:


<% form_tag destroy_marked_users_path, :method => :put do %> <% for user in @users %> <%# @users.each do |user| %> <% end %>
<%= check_box_tag "user_ids[]", %> <%=h %> <%= link_to 'Show', user_links_path(user) %> <%= link_to 'Edit', edit_user_path(user) %> <%= link_to 'Destroy', user, :confirm => 'Are you sure?', :method => :delete %>

<%= submit_tag "Destroy_marked" %> <% end %>

In user_controller.rb I have:
def destroy_marked
@user.destroy_all(:id => params[:user_ids])

and routes.rb:
map.root :controller => “home”
map.resources :users, :has_many => :links, :collection => {
:destroy_marked => :put }

When I click Destroy_marked on index-page, I get error:‘Couldn’t find
User with ID=destroy_marked’

I guess there is something wrong with routes? I just can’t figure out
what, I don’t understand the routes :frowning:

Here is the development.log (it shouldn’t say ‘Processing
UsersController#update’???) :
