Ruby Programming Language :: Update scaffolding form field


	Update scaffolding form field This may be a basic question, but i have an "image" field in a "news" table, and have a form that uploads the image. Following the upload, the "new" action is called in the rails scaffolding so i can add the rest of the news to db entry. I however want the "image" field to contain the image id that was just created in my image table. I send the value to the new action, but cannot get the field to default to this value. I have tried :locals => { :image => :id} to see if that overrides the default value set in the partial. As i am fairly unfamiliar with where the scaffolding is storing the information for this form I am having trouble figuring this out. Here is the code for the view. The second form is the form I am using to upload the image. So my question is how do i get the image field to use a default value that was passed to the view rather than what is stored as default in my db. <h1>New news</h1> <%= start_form_tag :action => 'create' %> <%= render :partial => 'form'%> <%= submit_tag "Create" %> <%= end_form_tag %> <%= form_tag({:action=>'save_picture'}, :multipart => true)%> <input type="file" name="picture_file" /> <input type="submit" name="Upload" /> </form> <%= link_to 'Back', :action => 'list' %>
