Hello!

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 🙂

index.html.erb:

 \<% form\_tag destroy\_marked\_users\_path, :method =\> :put do %\> \<% for user in @users %\> \<%# @users.each do |user| %\> \<% end %\>

| Name |
| --- |
| \<%= check\_box\_tag "user\_ids[]", user.id %\> | \<%=h user.name %\> | \<%= 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])  
end

* * *

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 ☹

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