Checkbox for array Rails

Question

I have an Activity and Type Model.

Activities has_many Types, Types has_many Activities

I would like to have checkboxes for all types when I create an activity so the ones that are checked, are the types of the new activity.

in my controller I did send all the types(@types) and in my view i did this

<div class = "field">
   Choose types:
   <% for type in @types %>
      <%= f.check_box :type %>
   <% end %>
</div>

I get an error undefined method 'type'
I don't know what to do in the create action to get this to work

type is a reserve keyword for single table inheritance

I tried this and saw the html generated and it works. My problem is, how do I access this information in the controller?

params[:type_ids]=["and all checked type ids will come here"] #["1", "2"]

   <% @types.each do |type| %>
      <%= check_box_tag 'type_ids[]', type.id %> <%= type.id %>
   <% end %>

Thanks, but now in my controller should i expect a params[:type]?

What is in @types? View generated html source.

@types =Types.all. So I want to be able to choose the type of the activity using this checkbox. I saw the html source and notices all the checkbox had the same value but I want the value for the checkbox to be the id of type
