Images not uploading in Database Rails 5 | Paperclip - ruby-on-rails

Question

I'm unable to upload an image in my nested scaffold form.
All other fields are getting in the database except the image. Please help!
I am on rails 5.2 and using paperclip for image uploading and images need to be uploaded on AWS.
I am not getting any errors its just the images are not entering the database.
Thanks!

Answer 1

in your model, you have:
has_attached_file :image
So I am assuming, Every Content has only one Image attached with it, but in you form in views, you are uploading multiple images as an array.
<%= f.file_field "images[]", type: :file, multiple: true %>
Change this to:
<%= f.file_field :image %>
Also, in you ContentController, in content_params action, change :images param to :image
params.require(:content).permit(:post_copy, :is_facebook, :is_instagram, :is_twitter, :is_youtube, :price, :image)
But, if you want attach multiple images then you have to change the approach entirely.

Answer 2

To have paperclip supported uploading to s3, you need to add gem "aws-sdk-s3" to Gemfile file? And set s3_credentials in model
class Content < ApplicationRecord
#
# rest of codes
###
has_attached_file :image, styles: { medium: "300x300>", thumb: "100x100>" } ,
:storage => :s3,
:s3_credentials => {
:bucket => "xxx",
:access_key_id => "xxx",
:secret_access_key => "xxx"}
#rest of code
end
FYI https://www.rubydoc.info/gems/paperclip/Paperclip/Storage/S3
