Hello there. :-)
I have this view:
<%= form_tag({:action => ''create''}, :multipart =>
true) %>
<table>
<tr>
<td>User</td><td><%=
text_field("user","name") %></td>
</tr>
<tr>
<td>Image</td><td><%=
file_field("user","img") %></td>
</tr>
</table>
<%= submit_tag "Create new user", :class =>
"submit" %>
<%= end_form_tag %>
I use this form to upload an image. On the controller I have:
def create
params[:user][:img] = params[:user][:img].read
@user = User.new(params[:user])
if @user.save
...
It reads the content of the file, saves it ok, but two questions:
First, is it ok to read on the controller? I saw samples on both the
controller and the model (on the model it just did not worked for me -
using img_field.read gives an error telling me
undefined method `read'' for #<String:0xb651c3d4>
Second, how, with just those two fields, with no other field on the form
with content-type and so on (I saw some samples with that), make sure
that the user will only upload, for example, PNG files? I made some code
on the controller, but is there a way to do that on the model?
I saw on "Agile Web Development with Rails" that they used a
validates_format_of :content-type, :with => /^image/
on the model, but as I don''t want to have a content_type field (and
don''t want to), is there a way do validate this?
Thanks!

I haven''t read you code, but why don''t you use the file_column plugin ? It just works and solves a lot of problems related to image upload On 4/10/06, Eust?quio Rangel <eustaquiorangel@yahoo.com> wrote:> > Hello there. :-) > > I have this view: > > <%= form_tag({:action => ''create''}, :multipart => true) %> > <table> > <tr> > <td>User</td><td><%= text_field("user","name") %></td> > </tr> > <tr> > <td>Image</td><td><%= file_field("user","img") %></td> > </tr> > </table> > <%= submit_tag "Create new user", :class => "submit" %> > <%= end_form_tag %> > > I use this form to upload an image.
