Syntax Error in code for 'bootstrap Custom forms' in Ruby - ruby-on-rails-3

Question

<%= form_for :content, url: contents_path, method: :post do |f| %>
<%= f.label :inout %> <!-- 수입 지출 목록 -->
<%= f.text_field :inout %><br>
<div class="input-group mb-3">
<div class="input-group-prepend">
<label class="input-group-text" for="inputGroupSelect01">Options</label>
</div>
<select class="custom-select" id="inputGroupSelect01">
<option selected>Choose...</option>
<option value="1">결혼식</option>
<option value="2">장례식</option>
<option value="3">돌잔치</option>
</select>
</div>
<% if option == 1? %>
<%= f.hidden_field :category, value=>"결혼식" %>
<% end %>
<%= f.label :title %>
<%= f.text_field :title %>
<%= f.label :cost %>
<%= f.text_field :cost %>
<%= f.label :memo %>
<%= f.text_area :memo %>
<%= f.submit %>
<% end %>
I'm getting the following syntax error in my code :
Unexpected ";", expected ";" .... syntax error, unexpected keyword_ensure, expecting_end_of_input
enter image description here
If I select option value one, I store "결혼식" in category
and I want to see "결혼식" in the show view
Can you identify what is causing the error?

Answer 1

Did you copy and paste the code from somewhere else? It's quite possible there might be some zero-width space or other hidden characters in your code that the ruby compiler is not liking.
You can use sublime text on OS/X or Notepad++ to try and see if there are hidden characters in your code.
If you're on OS/X or Linux, you can use Sublime Text and this plug-in to identify those characters

import sublime_plugin
class ShowZeroWidthSpace(sublime_plugin.EventListener):
def on_modified(self, view):
spaces = []
p = 0
while 1:
s = view.find(u'\u200b', p + 1)
if not s:
break
spaces.append(s)
p = s.a
if spaces:
view.add_regions("zero-width", spaces, "string")
else:
view.erase_regions("zero-width")
If you're on Windows, you can try using Notepad++ and changing the encoding to Encode in utf-8 BOM
If allo , you can also create a new ruby file and type in the code manually to ensure there's no zero-width or invisble characters that ruby doesn't like.
