I have 3 tables A, B and C
Table A has_many Cs
Table B has_many Cs
so C contains 2 foreign keys, A_id and B_id)
I have a screen with 2 lists : A list and B list
I would like to be able to create a C record by simply dropping an A
element on a B element
I tried this :
<ul id="A_list">
<% for A in @As %>
<% draggableA_id = "draggableA_#{A.id}" %>
<li id=<%= draggableA_id %> class="draggableAs">
<% A.name %>
</li>
<%= draggable_element(draggableA_id, :revert=>true) %>
<% end %>
</ul>
<ul id="B_list">
<% for B in @Bs %>
<% droppableB_id = "droppableB_#{B.id}" %>
<li id=<%= droppableB_id %> class="droppableBs">
<%= B.name %>
</li>
<%= drop_receiving_element(droppableB_id,
:accept => "draggableAs",
:with => "''draggableA='' +
(element.id.split(''_'').last())",
:url => {:action=>:create_C}
)%>
<% end %>
</ul>
It drops OK, but :
1) The problem is, the ":with" parameter takes only one key. How do I
convey the second one ? It doesn''t seem to accept a hash...
2) When I debug, I see that the draggableA_id that I drop is always
the last draggableA_id, whichever draggableA I drag...

It doesn''t seem to accept a hash...There''s some examples of the usage of :with here: http://www.spacevatican.org/2008/5/17/with-or-without-you-link_to_remote-s-mysterious-parameter (it''s mostly about link_to_remote but that doesn''t matter) Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
