I generated code with ruby script/generate scaffold_resource
Whenever I go to edit an image in filecolumn it creates a whole new record with the new image, as opposed to overwriting the image.
My Question is about the second block of code. How can I pass the ID so that I can update the record instead of creating a duplicate with a different image?
Here is my code.
Create View (works fine): <h2>New kellymadison</h2>
<%= error_messages_for :km %>
<% form_for(:km, :url => kms_path, :html => { :multipart => true }) do |f| -%> <p> <label for="Title">Title:</label> <%= f.text_field :title %> </p> <p> <label for="Description">Description:</label> <%= f.text_area :description %> </p> <p> <label for="wmv">URL for WMV:</label> <%= f.text_field :wmv_link %> </p> <p> <label for="wmv">URL for MOV:</label> <%= f.text_field :mov_link %> </p> <p> <%= file_column_field "km", "image" %> </p> <p> <%= submit_tag 'Create' %> </p> <% end -%>
<%= link_to image_tag("/images/back.gif"), km_path, :class => 'back- btn' %>
Edit View (The VIEW I AM HAVING TROUBLE WITH. It creates a new record witha new ID)
<h2>Edit km</h2>
<%= error_messages_for :km %> <% form_for(:km, :url => km_path, :html => { :multipart => true }) do |f| -%> <p> <label for="Title">Title:</label> <%= f.text_field :title %> </p> <p> <label for="Description">Description:</label> <%= f.text_area :description %> </p> <p> <label for="wmv">URL for WMV:</label> <%= f.text_field :wmv_link %> </p> <p> <label for="wmv">URL for MOV:</label> <%= f.text_field :mov_link %> </p> <p> <% @km = Km.find(params[:id]) %> <%= file_column_field "km", "image" %> </p> <p> <%= submit_tag "Update" %> </p> <% end %>
