Problem with non-ascii characters in forms: "incompatible character encodings: UTF-8 and ASCII-8BIT"
Hi
First off, I''m using Ruby 1.9.1p378 and Rails 2.3.8.
I was creating a minimal application to test handling of Norwegian special
characters when I bumped into this strange problem...
I have a simple Car model with fields maker:string and model:string.
For the controller I planned to just have an index action do all the work:
class CarsController < ApplicationController
def index
if request.post?
@car = Car.new(params[:car])
@car.save
end
@cars = Car.find(:all)
end
# def create
# @car = Car.new(params[:car])
# @car.save
# redirect_to :action => :index
# end
end
The corresponding view lists all car models and displays a form to support
the addition of new car models:
<h1>Cars</h1>
<table>
<th>maker</th><th>model</th>
<% @cars.each do |car| %>
<tr>
<td><%= car.maker %></td>
<td><%= car.model %></td>
<td>
<% end %>
</table>
<% form_for(:car, :url => { :action => "index" }) do |f|
%>
<p>
<%= f.label :maker %>
<%= f.text_field :maker %>
</p>
<p>
<%= f.label :model %>
<%= f.text_field :model %>
</p>
<p>
<%= f.submit ''Add'' %>
</p>
<% end %>
Now, this works fine..... until I submit special characters in one of the
fields.
If I for example write "Dodge" and "Børnout" in the form
fields, I get an
error like this:
Encoding::CompatibilityError in Cars#index
Showing *app/views/cars/index.html.erb* where line *#19* raised:
incompatible character encodings: UTF-8 and ASCII-8BIT
Extracted source (around line *#19*):
16: </p>
17: <p>
18: <%= f.label :model %>
19: <%= f.text_field :model %>
20: </p>
21: <p>
22: <%= f.submit ''Add'' %>
But, the entry is added correctly to the database anyway, so if I just
reload http://localhost:3000/cars, I do see the new entry.
OK, I thought... I''ve read quite a few places that there have been (and
still are) various issues with support for Unicode in the different
Ruby/Rails version combinations, so I figured that I just didn''t have
the
best combination for this.
But then I temporarily built a new application by using generate scaffold,
and it all works fine there.
After some trying and failing I discovered that if I (in my original
solution) changed the form_for :url option to :action => "create"
and added
a create action in the controller file (commented out in the above
controller source), it works with special characters and all.
So the only difference is that the form posts the data to the create action
instead of the index action, and then it works.
I just don''t get it! :o/
Anyone has an explanation to offer?
Would be much appreciated! :o)
Kind regards,
Rolf

Hahaha! Search the list, and you''ll notice that people have already fallen into this trap. Wait ''til Rails 3 AND Ruby 1.9.2 get released to jump to Rails+Ruby1.9 Stick to Rails 2.3.8 and Ruby 1.8.7 until then. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I did search the list, and I found people have similar problems with Ruby 1.9.1, but not directly comparable to my issue. In my simple case it DOES work, as long as I use two controller actions instead of just the one... Meanwhile.. yes, do do stick to Ruby 1.8.7 until I know more :o) Best regards, Rolf Fernando Perez wrote:> Hahaha! > > Search the list, and you''ll notice that people have already fallen into > this trap. > > Wait ''til Rails 3 AND Ruby 1.9.2 get released to jump to Rails+Ruby1.9 > > Stick to Rails 2.3.8 and Ruby 1.8.7 until then. >On Sun, Aug 1, 2010 at 2:53 AM, Rolf Pedersen <rolfhsp-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi > > First off, I''m using Ruby 1.9.1p378 and Rails 2.3.8. > > I was creating a minimal application to test handling of Norwegian special > characters when I bumped into this strange problem... > > I have a simple Car model with fields maker:string and model:string. > For the controller I planned to just have an index action do all the work: > class CarsController < ApplicationController > def index > if request.post? > @car = Car.new(params[:car]) > @car.save > end > @cars = Car.find(:all) > end > # def create > # @car = Car.new(params[:car]) > # @car.save > # redirect_to :action => :index > # end > end > > The corresponding view lists all car models and displays a form to support > the addition of new car models: > <h1>Cars</h1> > <table> > <th>maker</th><th>model</th> > <% @cars.each do |car| %> > <tr> > <td><%= car.maker %></td> > <td><%= car.model %></td> > <td> > <% end %> > </table> > > <% form_for(:car, :url => { :action => "index" }) do |f| %> > <p> > <%= f.label :maker %> > <%= f.text_field :maker %> > </p> > <p> > <%= f.label :model %> > <%= f.text_field :model %> > </p> > <p> > <%= f.submit ''Add'' %> > </p> > <% end %> > > Now, this works fine..... until I submit special characters in one of the > fields. > If I for example write "Dodge" and "Børnout" in the form fields, I get an > error like this: > Encoding::CompatibilityError in Cars#index > > Showing *app/views/cars/index.html.erb* where line *#19* raised: > > incompatible character encodings: UTF-8 and ASCII-8BIT > > Extracted source (around line *#19*): > > 16: </p> > 17: <p> > 18: <%= f.label :model %> > 19: <%= f.text_field :model %> > 20: </p> > 21: <p> > 22: <%= f.submit ''Add'' %> > > > But, the entry is added correctly to the database anyway, so if I just > reload http://localhost:3000/cars, I do see the new entry. > OK, I thought...

Next, if you''re planning to upgrade your application to Rails 3 and Ruby 1.9.2, I would recommend that you begin the process now so that you can provide feedback to the Rails team as well as the Ruby gem/plugin authors.
