ruby - Rails - How can I display one nested attributes (Solved) -

I have a new problem, I create a web where I have uploaded several indexes, using nested attributes and polymorphic tables By doing, I want to show only one image .html in my index, but I do not know how. But I am new to the rail

photography RB

  class photography & lt; ActiveRecord :: Base Valid: Title ,: Description, Attendance: True_key: User has_many: as images, as: imageable, dependent: delete accepts_nested_attributes_for: images ,: reject_if = & gt; Lambda {| One | A [: img_str] .blank? } ,: Allow_destroy = & gt; True end  

image.rb

  class image & lt; ActiveRecord :: Base is_to: imageable, polymorphic: correct mount_uploader: img_str, AssetUploader end  

index.html.erb

  & lt;% of photos For @ photo% & gt; & Lt;% = link_to photo.title, photography_path (photo)% & gt; & Lt;% photo.images.each do | Picture | & Gt%; & Lt;% = images.img_str% & gt; & Lt;% end% & gt; & Lt;% end% & gt;  

For the method I show all the image, try adding the first add, but for the first 5 the undefined method says: Fixnum. I think I would make a helpful method, but I'm not sure. Can somebody help me out?. Thanks

Try:

In addition, in Ruby, little is used for instead:

  & lt;% @ photos.each do | Picture | & Gt%;
