Question

UPDATE regarding accessing uploaded_picture:
======>
The culprit was in ImageItem.rb where I had call to upload_picture as private. Apparently controller call with parms.require.permit is a public call to attr_accessor with before_create on that variable.
With regard to .create! and .update! this param def is working:
def item_image_params
params.require(:items).require(:item).require(:item_images).permit(:item_image_caption, :uploaded_picture)
end
===== >
Request parameters are exactly -- with regard to structure:
See below...

This is not working:
def contact_preference_params
params.require(:contact_preference).permit(:item_id, :user_id, :use_which_contact_address,
:contact_by_chat, :contact_by_email, :contact_by_home_phone, :contact_by_cell_phone,
:contact_by_alternative_phone, :contact_by_Facebook, :contact_by_Twitter, :contact_by_Instagram,
:contact_by_LinkedIn, :contact_by_other_social_media, :contact_by_other_social_media_access)
end
Nor this:
def contact_preference_params
params.require(:items).require(:contact_preference).permit(:item_id, :user_id, :use_which_contact_address,
:contact_by_chat, :contact_by_email, :contact_by_home_phone, :contact_by_cell_phone,
:contact_by_alternative_phone, :contact_by_Facebook, :contact_by_Twitter, :contact_by_Instagram,
:contact_by_LinkedIn, :contact_by_other_social_media, :contact_by_other_social_media_access)
end
def contact_preference_params called from:
def update_cp
#pid = params[:items][:item][:participant_id]
#item_id = params[:items][:contact_preference][:item_id]
#current_item = nil
if #item_id.nil?
#current_item = ContactPreference.create!(contact_preference_params)
else
#cp = ContactPreference.where("participant_id = :pid and item_id = :iid", {pid: #pid, iid: #item_id }).first
#current_item = #cp.update!(contact_preference_params)
end
#current_item
end
Discovered I had an error in def, def update_cp
What worked is:
def contact_preference_params
params.require(:items).require(:contact_preference).permit(:item_id, :user_id, :use_which_contact_address,
:contact_by_chat, :contact_by_email, :contact_by_home_phone, :contact_by_cell_phone,
:contact_by_alternative_phone, :contact_by_Facebook, :contact_by_Twitter, :contact_by_Instagram,
:contact_by_LinkedIn, :contact_by_other_social_media, :contact_by_other_social_media_access)
end
====== >> UPDATE
Discovered another problem;

How does one access items => item => item_image => uploaded picture when uploaded_picture is an attr_acessor in model.rb
item_image.rb
class ItemImage < ApplicationRecord
belongs_to :item
attr_accessor :uploaded_picture, :item_type
before_save :uploaded_picture
private
def uploaded_picture=(picture_field)
unless (picture_field.blank?)
begin
name = self.item_id.to_s + '_' +
File.basename(picture_field.original_filename).gsub(/[^\w._-]/, '')
directory = './app/assets/images/' + self.item_type.to_s
path = File.join(directory, name)
# write the file -- b is for binary
File.open(path, "wb") { |f| f.write(picture_field.read) }
self.image_file_name = name
self.image_content_type = picture_field.content_type.chomp
self.image_width = 0
self.image_height = 0
.... end
image_image table:
Field | Type | Null | Key | Default | Extra
item_image_id | int(11) | NO | PRI | NULL | auto_increment |
|
item_id | varchar(40) |
image_content_type | varchar(20) |
image_height | int(3) |
image_width | int(3) |
image_file_name | varchar(150) |
item_image_caption | varchar(50) |
...

<%= item_images.hidden_field :item_image_id %>
