I would like to know how I can manually enter the options of a select, I have been using the following:
<%= f.collection_select :establecimiento_id, Establecimiento.order(:nombre), :id, :nombre, include_blank: true %>
but that is useful to select data from a table, I want to create one with the months, will it be necessary to create a table with the months or is there a way to enter in the code what I want?
You could create an arrangement with the months of the year:
@months = ["january", "february", "march", ... ]
and use the builder f.select as follows:
<%= f.select :month, options_for_select(@months.each_with_index.map { |m, i| [m, i] }) %>
This would generate something like
...
<option value="0">january</option>
<option value="1">february</option>
...
o If you expect a particular value for each month you could start from a Hash
@months = {"jan": "Enero", "feb": "Febrero" ... }
and the builder would be:
<%= f.select :month, options_for_select(@months.map { |k, v| [v, k] }) %>
