It's not clear why we're including therubyracer in the Gemfile.
@nathanvda - I have made sure the rest of codes are exactly like as your demo example.
Using:
rails (4.1.8)
simple_form (3.1.0)
undefined method `reflect_on_association' for NilClass:Class
When you called:
<%= link_to_add_association 'Add', f, :study_plan_subjects %>
The rest of code are exactly like this example.
if during rake db:migrate the following error occurs:
NoMethodError:
undefined method last_comment' for #<Rake::Application:0x007f2e4ce09cd8>
then a quick fix can be edit ./Rakefile and add these lines before calling Rails.application.load_tasks
require File.expand_path('../config/application', __FILE__)
require 'rake'
+ module TempFixForRakeLastComment
+ def last_comment
+ last_description
+ end
+ end
+ Rake::Application.send :include, TempFixForRakeLastComment
CocoonSimpleFormDemo::Application.load_tasks
sorry, not the good place for that...
How would I go about displaying images from a partial in a view using this gem. For example, I have a profile that has many products. In my view I have something like this for text fields:
<% @editprofile.products.each do |product| %>
<strong>Product/Service:</strong>
<%= product.prodserv %>
<strong>Product Description:</strong>
<%= product.productdesc %>
<% end %>
What should I put to display images from the product partial?
Product Partial:
<div class='nested-fields'>
<p><b> Product (s) Name (Max 75 characters): </b></p>
<%= f.input :prodserv, label: "Products" %>
<p><b>Description</b> (Maximum 500 Characters)</p>
<%= f.input :productdesc, label: "Product Description" %>
<p><b>Upload Pictures: </b>(Note: You can upload a total of two files (picture, audio, video, ppt, MSWord, Excel)
for each product or service)</p>
<%= f.file_field :upload %>
<%= f.file_field :upload2 %>
<p><b>Attached Product Information</b></p>
<%= f.file_field :urlimage %><%= link_to_remove_association "remove url", f %>
<%= f.input :url, label: "Product URL" %>
</div>
