materialize-sass | Materializecss rubygem for Rails Asset Pipeline / Sprockets

I am trying to create a form so a user can save a setting which has their default teams (multiple) and their professions (single). I can do this using simple_form and the lines of code below, but I am trying to use autocomplete as the dropdown lists do not work well with my design.

• <%= f.association :profession %>
• <%= f.association :team, input_html: { multiple: true } %>

I am loading the JSON from a collection into an attribute data-autocomplete-source within my inputs, a short bit of jquery then cycles through each of these and then initialises the materialize .autocomplete, I also need to do this with .chips for many associations.

The UI element is working as I would like, but I cannot work out how to save a new record. I have two problems:

1. Unpermitted parameters: :team_name, :profession_name - I've been trying to adapt this tutorial and believed that Step 11 would effectively translate this within the model, but am clearly not understanding something...
2. "setting"=>{"team_name"=>"", "profession_name"=>"Consultant Doctor"} - the team_name values (i.e. the chips) are not being recognised when attempting to save the record. I've got some nasty jquery that transfers the id from the div to the generated input which I was hoping would work...

I've also checked many previous questions on Stack Overflow (some of which seem to be similar to this question, generally using jqueryui) but cannot work out how to adapt the answers.

How can I use the names from a model in a materialize chip and autocomplete input and save the selections by their associated id into a record?

Any help or guidance would be much appreciated.

I've updated my app to rails 5.1 and spree to spree 3.5 this caused several problems with the latest being.

I'm using Spree on my Ruby on Rails app, and I'm having the following error

I'm trying to install PostgreSQL on my Ruby app, and am running into a problem. Whenever I'm trying to start my server I get an error stating:

rescue in spec': Specified 'postgresql' for database adapter, but the gem is not loaded. Add gem 'pg' to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

which is weird because I've already added it to my Gemfile and ran bundle install and ran bundle list to check if it's been installed (which it is).

To run you through to what I've done.

I've started my PostgreSQL database, created a database and gave it a name & password.

Then I've changed the database.yml to:

I am using materialize-sass gem on a form. Using autocomplete feature to get Vendor names. other fields on the form are item names and quantity which are a nested resource. For this I am using cocoon gem

For some reason the very first time the page loads, all seems to work fine. But adding more fields does not seem to be working. I tried using drop down select and that does not show the list of items. I replaced it with another autocomplete and the main field does show however the auto complete feature does not work. Any idea what may be wrong?

Please see my code below.

First, I removed gem 'turbolinks' and removed the code requiring Turbolinks in the application.js file. So, I successfully disabled Turbolinks in my local machine. Then, I pushed my changes to Heroku, but Turbolinks is still working in production.

How can I disable Turbolinks in Heroku?

When I ran this code:

I have a Rails 5 app with turbolinks + Materialize css via gem.

I have strange behaviour with "double autofocus" on input:
