How to disable a select associaition from simple form

Question

I have a select Association of the simple form, the value of it passed via controler and I wish that in the form the user did not have the option to select another value. I have tried using disabled:true (Disables as I want but does not send the value when saved) disabled: [true], input_html: {disabled: true} and readonly: true, none of which solved the problem, always allowing selecting another value in select. Any suggestions on how to display the selected value without the user being able to select another?

Answer 1

You can exchange the select field for a plain text field when you are on the edit screen or put no field keeping only the text in a div.

Another option is to keep it like this and create a rule in the model before_update not allowing the value initially recorded not to be changed.
