Could you share the code?

Thanks!

I joined GitHub Education. How can I validate the account in Gorails to take advantage of the benefit?

How can you upload images with ActiveStorage from the API?

Backend: API Rails
Frontend: Reactjs

Github: https://github.com/nicobobb/graphql-rails-blog

Verify if the image exists before:

<% if post.photo.attached? %>
   <%= image_tag post.photo %>
<% end %>

In the aplication, users have to upload files, I plan to use Amazon S3.
Do you recommend using Rails 5.2 Active Storage, or using the Gem Shrine as explained in Gorails?

What do you recommend?

Thanks Jack! As you said, I solve it

How do I save the user_id by adding the mail?

For the relationship, you have to save the user_id, but to be more dynamic for the user, I want to the users search other users by the email and rails save the id as usual.

How is it done?

In the views I have:

 <div class = "field">
     <% = form.label: user_id%>
     <% = form.text_field: user_id, id%>
   </ div>

 I'm using Devise.

Thanks for all your help!! :)

I have access to current_user in model ?

I'm try:

def classroom_params
       params.require(:classroom).permit(:name, :owner_id => [current_user])
end

But don't work because "owner.required".

Some values by default and others by strong parameters from the views

Without using any gems how do I do this in rails? I see the gem Ancestry (https://github.com/stefankroes/ancestry)

Main Category
Sub Category
 Sub Category
    Sub-sub Category

Main Category

     Sub-sub Category
          Sub-sub-sub Category

How would the relationship between models?

In many projects created with Rails I see that they do not use any gem to give permissions, for example Gitlab:

https://gitlab.com/gitlab-org/gitlab-ce/blob/master/Gemfile

What method is used today to give permits?
