My application manages hierarchical classifications based on lists of values (dictionnaries). At some point, I need to import the parent-child relationships from an Excel sheet, and create persisted ValuesToValues objects.

Based on Ryan Bates' RailsCast 396, I created the import model in which the main loop is:

I have two models, Preset and Plot, as below:

I am trying to implement a simple search and sort for my webapp. I am following the railscast and this railscast.

My application helper for sortable function which I am using as link is:

I am trying to reproduce the functionality as demonstrated in railscast episode 196 Nested Model Form which is quite old.

The problem i am facing is that, Rails is currently displaying only one instance of question and choices instead of 3.

In my app the relevant models are paper, question and choice.

Relevant code chunks:

app/controllers/papers_controller.rb

I have been working my way through the Railscasts videos and trying to adapt them for the latest version of rails, being version 6. I am up to the following episode:

http://railscasts.com/episodes/124-beta-invitations

The video explains that you need to have some form of authorisation/authentication in place prior to the changes, so I followed the instructions on the following site to do so:

https://www.nopio.com/blog/authentication-authorization-rails/

I stopped at Step 20 as the final step was not needed. Here devise is the main gem used for most of the heavy lifting.

There is also a comment from some time after going down the same path as me and using devise which shows the following:

My Morris Line chart is not showing on initial page load. Manually using the browser refresh will result in the chart displaying as expected. This is under Rails 5 and Chrome/Safari/Firefox. My coffeescript file.

In Ryan Bates railscast on subdomains, he gives the following way to match subdomains

I'm running Rails 6.0.0.rc1 and having trouble getting a triple nested form working. I have products that have options that have option_values. So a Product might have an option called "Color" and an Option Value named "Red." I'd like to create all of these in a classic nested form in the Product form.

The form works and I can save Product with an Option, but not the Option Value on submit. I'm not sure why it's not working when I try to embed fields_for Option Values inside the fields_for Options.

What am I doing wrong here? I feel like I'm missing something obvious, but can't figure it out. (Probably not relevant, but note that I need to scope each object to account_id and my User has_one :account that's the reason for the hidden field.)

Here is my product model:
