I'm trying to store the image or video file in the database and along with image and video, i have some data to store.
I'm using fetch api to post the data and using ActiveStorage to store the image and video files. I have stored the text data to the database but unable to store the image and video files. Here below is the Section model
class Section < ApplicationRecord
belongs_to :layout,dependent: :destroy
has_many :media, through: :section_multimedia
has_many :section_multimedia, dependent: :destroy
has_one_attached :mediadata
end
Below is the show page along with javascript included
