hum, the question is the file it's represented in a model?anyway, i used
virtual attributes...
any questions, just ask =)
at sfile.rb
validate_on_create :validate_upload
def temp_file= temp_file
@temp_file = temp_file
end
protected
def validate_update
errors.add_to_base("Upload a valid Flash file") unless
validate_type_file @temp_file
end
def validate_type_file file
original_filename = file.original_filename
extension = SFile.ret_ext_file original_filename
reg_file = Regexp.new(/(flw)/)
if n =~ reg_file
return true
else
return false
end
end
def self.ret_ext_file n
v = n.split('.')
v = v[v.size-1].downcase
return v
end
at .erb
<h1>Welcome</h1>
<% form_for(@sfile) do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :title %><br />
<%= f.text_field :title %>
</p>
<p>
<%= f.label :description %><br />
<%= f.text_area :description %>
</p>
<p><%= file_field 'i', 'temp_file' %></p>
<p>
<%= f.submit 'Create' %>
</p>
<% end %>
at sfile_controller.rb
def create
@sfile = Sfile.new(params[:sfile])
@sfile.attributes = params[:i]
respond_to do |format|
if @sfile.save
flash[:notice] = 'File was successfully
created.'
format.html { redirect_to(@sfile) }
else
format.html { render :action => "new" }
end
end
end
