We would like to add a checkbox to each row on
Rails index page to flag for the row. This checkbox is not part of the object (no checkbox boolean in database). When the index page shows, a user can check the box to trigger an event for the row in following process:
#objects/checkbox_index.html.erb
<table>
<tr>
<th>CheckBox</th>
<th>Object Name</th>
<th>Object ID</th>
</tr>
<%= @objects.each do |obj| %>
<tr>
<td><%= checkbox %></td>
<td><%= obj.name %></td>
<td><%= obj.id %></td>
</tr>
<% end %>
</table>
In controller, the process will be like this:
@objects.each do |obj|
some_event if obj.checked
end
There are a couple of questions we don't quite understand:
1. How to declare an array checkbox variable on the form and link it to each row of obj? We have been using `attr_accessor` to declare var for a form.
2. How to retrieve each row on checkbox_index form and pass them back to controller? We are using simple_form for new/edit.
Can anyone point me towards any good examples of this sort of behavior, or suggest what we should be thinking about? Many Thanks.
