Rails attachment_fu db_file upload issue.

I've recently added attachment_fu to my applicatons, and it works without reporting any errors. Works fine in :file_system mode, but not in :db_file mode. It seems to upload only about 45 bytes of data instead of the entire image, image download works fine when I manually put the data in the database.

  I've created an Icon model that has the following has_attachment settings

has_attachment :content_type => :image,                  :storage => :db_file,                  :max_size => 1.megabyte,                  :resize => '75x75>',                  :processor => 'MiniMagick'

validates_as_attachment

I've removed the resize and processor statements and I'm fairly confident that the issue is not related to image processing. And again the upload works to storage type :file_system. My controller create method looks like this:

def create    @icon = Icon.new(params[:icon])    if @icon.save      flash[:notice] = 'Icon was successfully created.'      redirect_to :action => 'show', :id => @icon    else      render :action => :new    end end

And my 'new' view looks like:

<%= error_messages_for :icon %>

<% form_for(:icon, :url => {:action => 'create'},                      :html => { :multipart => true }) do |f| -%> <p>    <label for="icon">Upload An Icon</label>    <%= f.file_field :uploaded_data %> </p> <p>    <%= submit_tag 'Create' %> </p> <% end -%>

Any suggestions would be greatly appreciated.

Thanks, j

In your migrations for db_file use t.column :binary, :limit => 500.megabyte

You can us whatever the limit you want to keep

That should fix it

Joshua,

Don't know if you found the solution for this issue, but I thought I'd throw in my thoughts just in case. I've been having the exact same issue (corrupted uploads in the database with only 5 - 120 bytes, but full functionality using file_system mode), and I came across the following thread:

A posting by 'Adam' near the end of the thread looks like this:
