Rails 5 - Is there a way to convert if statement to controller logic?

I have an if statement in a loop that only displays posts from users followers:

    <% @posts.each do |post| %>
        <% if post.user.following?(current_user) && current_user.following?(post.user) %>
            <%= post.body %>
        <% end %>
    <% end %>

And this is my controller code for that loop:

@posts = Post.where('created_at >= :one_day_ago', one_day_ago: Time.now - 24.hours).order("created_at DESC")

Is there a way to get the if statement into my controller code?

Sure, it could look like this:

@posts = Post.where('created_at >= :one_day_ago', one_day_ago: Time.now - 24.hours).order("created_at DESC")
@posts = @posts.filter do |post|
  post.user.following?(current_user) && current_user.following?(post.user)
end

Then in your view you just render the filtered posts:

<% @posts.each do |post| %>
  <%= post.body %>
<% end %>
