updateSection: (section) => {         
    const iframe = document.getElementById('ifameId')
    const innerDoc = (iframe.contentDocument) ? iframe.contentDocument : iframe.contentWindow.document;          
    const selected_section = innerDoc.getElementById(section.id)
          
    selected_section('[data-page-setting="title"]').innerHTML = block.title
},

1. Users saves section.
2. Section#update updates section
3. Responds with json with something like: { resp: { data: @section: template: “ERB STRING”} }
4. Page editor updates the iframes section with the updated resp.template
5. Page editor updates the form fields with resp.data

I'm very excited about Stimulus and can't wait to see where it goes!

Thanks Jacob!

I have setup a service that parses and saves the result of an external API which all works great, however, I can't work out how to save the array of images that need to be saved in a has_many relation.

The service:

module Domain
  class FetchUserPosts

    def initialize(token)
      @token = token
    end

    def get_listings
      resp = client.get("/v1/some/api/posts")

      resp.body.each do |post|
       @user.posts.create(
          headline: post["headline"],
          body: post["body"],
          images: listing["media"].map { |l| l["url"]} ???
        )
      end
    end

    private

    def client
      Faraday.new(url: "https://example.com", headers: { "Authorization" =>  "Bearer #{@token}" }) do |f|
        f.request :json
        f.request :retry
        f.response :logger, Rails.logger
        f.response :raise_error
        f.response :json
        f.adapter Faraday.default_adapter
      end
    end

  end
end

The Post Model that it saves to:

class Post < ApplicationRecord
  belongs_to :user
  has_many :images, as: :imageable
end

And the associated Image model:

class Image < ApplicationRecord
  belongs_to :imageable, polymorphic: true
end

Everything works except I'm unsure how to deal with the images which look like:

[{
   "type" => "image",
   "url" => "https://image-1.jpg"
 }, {
   "type" => "image",
   "url" => "https://image-2.jpg"
}]

Did you see this? https://gorails.com/episodes/sortable-drag-and-drop

I have an external JSON API that I need to parse and save and was wondering if anyone had any suggestions on what to use?

I found tons of info on building a rails API but very little on consuming an external one.

I'm an idiot.

Thanks for all your help Jacob!

Your a legend!

It appeasr to be all working now except I'm unnsure how to set the user_id on Post

Post Model

class Post < ApplicationRecord
  belongs_to :postable, polymorphic: true
  belongs_to :user
end

Article Model

class Article < ApplicationRecord
    belongs_to :user
    has_many :posts, as: :postable
end

Review Model

class Review < ApplicationRecord
    belongs_to :user
    has_many :posts, as: :postable
end

Post Controller

class PostsController < ApplicationController
  def create
    # @post = current_user.posts.build(posts_params) << How do I do this now?
    @parent = parent
    @post = @parent.posts.new(post_params)

    respond_to do |format|
      if @post.save
        format.html { redirect_to posts_path, notice: "Post successfully created!"}
      else
        format.html { render :new }
      end
    end
  end

  private

  def parent
    Article.find(post_params[:article_id]) if post_params[:article_id]
    Review.find(post_params[:review_id]) if post_params[:review_id]
  end
end
