I am trying drag and drop in RoR for the first time.
What I want to achieve, is a list of slots, and a list of entries. You
should be able to drag an entry onto a slot and slot.entry_id will
update to match the dragged entry.entry_id.
I've spent a lot of time looking in textbooks and online, but cannot
get the drop_receiving_element to fire. When I release an item over
the slot, the item simply reverts. If someone could look through the
code I've pasted and gave a hint I would appreciate it.
1. Here is the VIEW for the page:
<% f.fields_for :slots do |builder| %>
<% element_to_drop_id = "slot" %>
<div id="slot" >
<%= builder.label :slot_number, "Slot Num" %>
<%= builder.text_field :slot_number %>
<%= builder.label :entry_id, "Entry Num" %>
<%= builder.text_field :entry_id %>
</div>
<%= drop_receiving_element("slot",
:accept => "entry",
:hoverclass => 'hover',
:with => "'entry=' + (element.id.split('_').last())",
:slot_id => :slot_id,
:url => {:action => :set_entry}
) %>
<% end %>
<div id="entry_list_to_move">
<%= render :partial => "entry_list_for_drag" %>
</div>
2. Here is the partial entry_list_for_drag
<% @entries.each do |entry| -%>
<% element_to_drag_id = "entry_#{entry.id}" %>
<div class="entry" id=<%= element_to_drag_id %> style="cursor:move">
<p>
<%= entry.title %>
<%= entry.body %>
</p>
</div>
<%= draggable_element(element_to_drag_id, :revert => true) %>
<% end %>
3. Entries and slots exist on pages. In the page controller I'm
starting to set up the below but I can't even get this to trigger
def set_entry
@slot = Slot.find(params[:slot_id])
entry_id = params[:entry]
@slot.entry_id = entry_id
end
