Activestorage image saved in blob but not showing in view

I'm following the rails ActiveStorage guide. I've successfully saved the image to the blob table in the local database (the attachment table is empty). But I can't seem to show it in the view:

<%= url_for(@comment.images) if @comment.images %>

does not work nor does:

     <% @comments.each do |c| %>
        <%= c.body %>

        <%= url_for(c.images) if c.images %>

      <% end %>

Showing other values of comment works, so this is specific to the images. I've also tried adding .url to "images." And I've tried image_tag instead of url_for. And looping through the images. And image_tag url_for (instead of using just one of them). And using representation. No luck in all of these cases. I'd really appreciate any help.

And my model

  has_many_attached :images

application.js

//= require activestorage


import Rails from "@rails/ujs"
import Turbolinks from "turbolinks"
import * as ActiveStorage from "@rails/activestorage"
import "channels"


Rails.start()
Turbolinks.start()
ActiveStorage.start()

controller



    private
        def comment_params
            params.require(:comment).permit(:body, images: [])
    end

The solution was to change file upload form from

<%= form.file_field :images, multipart: true, direct_upload: true %>

to

<%= form.file_field :images, multiple: true, direct_upload: true %>

It was not uploading before, and somebody had suggested switching to "multipart." It solved the uploading in appearance but it was not attaching the image.

I guess the uploading in appearance also works now because I tweaked something as I frantically tried multiple things.

Now the attachments table is populating with images. Before only the blob table was populating.

You have specified has_many_attached, so @comment.images will contain an array of images, So the following code will display the first image of your comment.

     <%= image_tag(@comment.images.first) if @comment.images.attached? %>

If you want to display all images you can iterate through @comment.images array and display each image
