Adding a custom JSONB text_field tag with simple_form

Question

I have a JSONB type options column on a model in my Rails application and I am in a situation where I need to provide JSONB nested parameters manually for every single form. That's why the official solution proposed here is not an option.

So I might want to have something like:

options[first_name], options[last_name]

for one instance, and a totally different set for another:

options[pet_dog], options[frank_sinatra]

I assume it can well be implemented using something like

= f.text_field :options[pet_dog]

But it's not working.

Answer 1

My solution code looks like this:

View form:

= f.simple_fields_for :options do |p|
  - @options.each do |o|
    = p.input o.name.to_sym, input_html: {value: o.default_value}

Controller

def new
  @options = Model.options
  ...
end

def create
  @job  = current_user.jobs.build(job_params)
end

...

def job_params
  params.require(:job_request).permit(
  ...
  options: get_options)
end

def get_options
  some_model.options.pluck(:name).map(&:to_sym)
end

Possibly this will help someone.
