発生している問題・エラー
RuntimeError in Public::Posts#index
Showing /home/ec2-user/environment/reco_ani/app/views/public/posts/index.html.erb where line #6 raised:
Ransack needs Post attributes explicitly allowlisted as
searchable. Define a `ransackable_attributes` class method in your `Post`
model, watching out for items you DON'T want searchable (for
example, `encrypted_password`, `password_reset_token`, `owner` or
other sensitive information). You can use the following as a base:
```ruby
class Post < ApplicationRecord
# ...
def self.ransackable_attributes(auth_object = nil)
["body", "created_at", "genre_id", "id", "title", "updated_at", "user_id"]
end
# ...

@post = Post.new(post_params)
@post.user_id = current_user.id
