Posted in Simpleform association with images!

It's been a long week! :) Thanks for taking the time anyway, it's very much appriciated!

You also have a weird ability to create videos which contain stuff I'm working with at the time! You think you could point me in the right direction with this?

It was just me being an idiot Chris, I didn't create the join table for messages and vehicle_images. Schoolboy error.

Thanks again.

Hmm, when I don't add any images I get 'VehicleImage(#70203987369520) expected, got String(#47143662444640)'

Thanks for taking a look Chris.

I do have message_id on Buckets.

class CreateBuckets < ActiveRecord::Migration
  def change
    create_table :buckets do |t|
      t.integer :message_id
      t.datetime :expires_at
      t.integer :vehicle_id
      t.integer :vehicle_images

      t.timestamps null: false

Here is the various bits 'n bobs in gist

Thanks again!

Hi Chris,

I'm wondering if you could help. I'm currently building a form that'll send out a SMS with twilio, and i'm looking to send details of a vehicle out at the same time, specifically the images of that vehicle. I have the form working perfectly except selecting which images are to be sent. If i run what i've put below I get 'can't write unknown attribute message_id'

<%= simple_form_for [@vehicle,] do |f| %>
  <%= f.error_notification %>

  <div class="form-inputs">
    <%= f.input :to %>
    <%= f.input :company %>
    <%= f.input :body %>

        <%= f.association :vehicle_images,
                                            :as => :check_boxes,
                                            item_wrapper_tag: :div,
                                            item_wrapper_class: "image-select",
                                            :collection => @vehicle.vehicle_images.order(:id),
                                            :label => false,
                                            :inline_label => false,
                                            :include_blank => false,
                                            :input_html => {multiple: true},
                                            :label_method => lambda { |b| image_tag(b.image.url(:thumb)) },
                                            value_method: :id


  <div class="form-actions">
    <%= f.button :submit %>
<% end %>

  def create
    @vehicle = Vehicle.find(params[:vehicle_id])
    @message =
    @message.vehicle_id =

    respond_to do |format|

        @bucket =
        @bucket.message_id =
        @bucket.vehicle_id =
        @bucket.vehicle_images = params[:message][:vehicle_image_ids]!


        format.html { redirect_to vehicle_messages_path(@vehicle), notice: 'Message was successfully created.' }
        format.json { render :show, status: :created, location: @message }
        format.html { render :new }
        format.json { render json: @message.errors, status: :unprocessable_entity }

Is there anyting silly I'm missing from what you can see here? I'm rushing out but if you need more info to give any feedback, just let me know.

Thanks very much, it's appriciated!

Posted in Saved messages as HTML

That's brilliant Chris, works perfectly! :) Thanks very much. Been playing around with it all night but I'm quite the novice when it comes to JS!

Posted in Saved messages as HTML

Hi Chris,

I'm wondering, on your episode, would it be possible to have one of the saved messages as HTML? I've tried entering <h1>test</h1><p>this is a test</p> but nothing appears once selected (just some whitespace). Plain text works fine.

This is what I see in the source:

        <option data-body="&lt;h1&gt;test&lt;/h1&gt;&lt;br&gt;&lt;p&gt;this is a test&lt;/p&gt;" value="1">Test</option>

It's obviously formatting it, but am I able to disable this?

Thanks Chris, I appreciate it.
