Hi, 

I'm using rails 6.0.3.4 and need to send emails automatically at the updating of my ArtistsMetric instance that

has_many_attached :justification_files

Here is my code in the ApplicationMailer: 

def artists_metric_verification_files
@artists_metric = params[:artists_metric]
mail(to:(to: "dontspam@me.com", subject: "<%= @artists_metric.artist.name %> infos updated at <%= @artists_metric.updated_at %> ")

And in artists_metric_verification_files.html.erb: 

<%= @artists_metric.artist.name %>
<%= cl_image_tag(@artists_metric.justification_files.each { |file| file, flags: "attachment"}) %>

My error is:

Encountered a syntax error while rendering template: check <%= @artists_metric.artist.name %> <%= cl_image_tag(@artists_metric.justification_files.each { |file| file, flags: "attachment"}) %>

 

By the way, I have tried to use the ancient syntax, but it doesn't work neither(same syntax error but with the "=>": 

<%= cl_image_tag(@artists_metric.justification_files.each { |file| file, :flags => "attachment"}) %>

Would you please help me? I'm pretty sure it is a very simple change but I can't find the answer...

  Can you loop artist_metrics outside of the cl_image_tag? Maybe something across these lines:

  <% @artists_metric.justification_files.each do |file| %>
  cl_image_tag(file, flags:attachment)
  <% end %>

  Hi @Resi,

  I'm not sure I understand what you mean - could you please provide more details/context about your response?

  Hi @Resi,

  I have tried to follow the instructions provided above but I didn't succeed. I think the post doesn't contain full details of information that I need.

  Hi @MichaelWik,

  In order to get a better understanding of the implementation that you would like to achieve, can you please help to open a support ticket here (https://support.cloudinary.com/hc/en-us/requests/new) and provide us the sample source code showing the errors you are encountering (e.g., through Github or Replit would be helpful)?

  Thanks.
