Select 'others' Option From Drop Down List Creating Text Field Ruby On Rails - 4.2

_form.html.erb

<%= f.label :description %><%= f.select(:description, options_for_select([['', ''],['METRO', 'METRO'], ['BUS'

Solution 1:

Found it - I'm kind of blind sometimes...

index.html.erb
<td class="col-1"><%= expense.description %>&nbsp;<%= link_to expense.description_other,{}, {:style =>'color: #CC3366'} %></td>

You've got two <%= ... %>'s in there ...

<%= expense.description %>

And then

<%= link_to expense.description_other,{}, {:style => 'color: #CC3366'} %>

Get ride of the first one when OTHER is selected, using an if conditional(the trinary operator we talked about <expression> ? <if true do this happens>: <if false this happens> The conditional would have to contain both statements inside one <%= ... %> block.

Also, you have an issue here ... should have a conditional of some sort ... probably the ||= & drop the Expense.new or the Expense.last.dup

defnew@expense = Expense.new

    @expense =  Expense.last.dup
  end
