html - Rails simple-form with multiple instances of the same object -


i trying create rails form using simple form uses nested resources. however, want able submit multiple instances of associated resource. example below explain better. 

<div class="tab-pane active" id="reminder">     <%= simple_form_for @collection, html: {multipart: true}, url: collection_index_path |m| %>          <%= render partial: "collection/tabs/reminder", locals: { :m => m } %>     </div>

-inside partial

<% 9.times |j|%>     <div class="tab-pane" id="<%= j %>">         <%= m.simple_fields_for :reminder |p| %>             <%= p.input :heading %>             <%= p.input :message %>         <% end %>                </div>

there tabbed pane in user can click through 9 tabs set 9 reminders, should associated collection (collection model accepts nested attributes reminder). however, way have setup now, controller gets set in last reminder in params. anyway ideas appreciated.

there must way distinguish tabs before submitting controller. , think answer might here. i.e. looks this:

<% 9.times |j|%>     <div class="tab-pane" id="<%= j %>">         <%= m.simple_fields_for :reminders |p| %>            <%= p.input :heading %>            <%= p.input :message %>         <% end %>     </div> <% end %>

css - SVG using textPath a symbol not rendering in Firefox -

using textpath within symbol doesn't render in firefox. renders fine in latest chrome , ie, when try reference symbol, svg text doesn't render in firefox (37.0.1) - first box appears empty. code below (no external dependencies), there should 2 boxes word test flowing vertically in centre of each. edit: thought issue somehow involved flexbox layout, until paul pointed out issue exists without flexbox layout. the html is: <div> <svg id="not_working" viewbox="0 0 250 1200" preserveaspectratio="xmidymid meet"> <symbol id="test_symbol1" preserveaspectratio="xmidymid meet" viewbox="0 0 250 1200"> <path id="test_symbol_path" d="m 100 1200 l 100 0" /> <text font-size="100" fill="red"> <textpath text-anchor="middle" startoffset="50%" xlink:href="#test_symbol_path&q
