I would like to duplicate _form.html to show different options to each person logged in, for example one person can see from f.select 4 options out of 20 that exist, another person can see 3 options out of 20.

How could I create this? I'm pretty confused how to do this

<% programa = {
 'Cemento/mortero' => 'Cemento/mortero',  'Laminas' => 'Laminas', 'Pintura' =>  'Pintura', 'Tinacos' => 'Tinacos', 'Aspersoras' => 'Aspersoras', 'Calentadores solares' => 'Calentadores solares', 'Baños ecológicos' => 'Baños ecológicos', 'Huertos de traspatio' => 'Huertos de traspatio', 'Mejoramiento de vivienda' => 'Mejoramiento de vivienda', 'Mejoramiento de escuelas' => 'Mejoramiento de escuelas ', 'Calzado escolar' => 'Calzado escolar', 'Ampliación de metas en obra pública y activos fijos.' => 'Ampliación de metas en obra pública y activos fijos.'} %>
<%= f.select :programa,programa, label: "Programa",  control_col: "col-lg-4"%>

Maybe you can create a table named program, with a field id and a field nombre . Also a user type that defines what programs that user can see. Then you create another called programs_type_user, which serves as a many-to-many connection, with a field usuario_id and programa_id .

In the model of type_users you make the connection with the one of programs:

has_and_belongs_to_many :programas

In the program model you make the connection with the type of users:

has_and_belongs_to_many :tipo_usuarios

In the user model you make the connection with programs:

belongs_to :tipo_usuario has_many :programas, through: :tipo_usuarios

Then you create in seed.rb what programs each type of user has access to, then in the user table you define with a tipo_usuario_id field to which type it belongs.

Finally in the form you can do something like this:

<%= f.select :programa, usuario.programas, label: "Programa", control_col: "col-lg-4"%>

You have many ways of doing it, I believe that with the information you give it is better to go to the simple for now.

What we are going to do is show a select or another depending on the user through a conditional. I'll take your example:

    <% programa = if condicion_1 
         { 'Calzado escolar' => 'Calzado escolar', 'Ampliación de metas en obra pública y activos fijos.' => 'Ampliación de metas en obra pública y activos fijos.'} 
                  elsif condicion_2   
         { 'Cemento/mortero' => 'Cemento/mortero',  'Laminas' => 'Laminas', 'Pintura' =>  'Pintura'} 
       end %> 

    <%= f.select :programa, programa, label: "Programa",  control_col: "col-lg-4"%>

In condicion_1 and condicion_2 you must set the conditions for which you want to show one or another set of options.

If you already want to improve your code a bit more, you may want to do this control in the controller and not in the view, introducing the set of options in another variable, leaving your view a bit cleaner.

You can also even create a model with the options and make a query, but I think this is already very complicated for the scope of the question you have asked. (If you need to expand any of the options please indicate in the comments).
