When multiple images were posted at the same time, I had to devise a description to display the images. I will post the article as a memo so that I will not forget the contents.
** I want to display the one with the lowest index number of multiple posted photos on the index screen **
section.fifth-headline %h2.title Pickup category .contentsbox .contents-title %h3.heading Newly posted products .contents-lists .contents-list - @newProducts.each do |product| =link_to "#" do .contents-list__itmes .contents-list--item = link_to product_path(product), class: "listBtn" do %figure.product__images = image_tag product.images.name.url, alt: "image_url",size: "200x150", class:"new-img" .contents-list--inner %h3.name = product.name .data %ul %li = product.price Circle %li %i.fa.fa-star.likeIcon 0 %p (tax included)
def index @newProducts = Product.includes(:images).where(status: 0).order("RAND()") ~abridgement~ end
If you have posted multiple images and want to display only the first one, you can get the index number  by writing as follows.
= image_tag product.images.name.url, alt: "image_url",size: "200x150", class:"new-img"
Also, in this case, you have to define the file to be called by the index action. Therefore, **. Where (status: 0) ** is defined and assigned to the instance variable.
@newProducts = Product.includes(:images).where(status: 0).order("RAND()")
I think this will work!
This time, "I can write like this! I thought, and wrote an article! I'm still studying, so if you find something wrong, please comment!
Thank you very much!
