Rails assign two attributes with one form item

I have an object with attributes first_team_name and second_team_name, and a list that has pairs of [team1, team2] values.

I would like to be able to have it so when I select an object in the form, it assigns team1 to first_team_name and team2 to second_team_name, but I have no idea how to split those values accordingly.

Is there anyway to split the values of my collection and put them to two different attributes of my object?

You can define 2 functions in your model

def team_names
  return "#{first_team_name},#{second_team_name}"
end

def team_names=(values)
  self.first_team_name, self.last_team_name = values.split(',')
end

Warnings

  • your select values must be like 'toto,titi'.
  • Choose an other separator if team name can include commas.

I think it is possible by parsing the arguments in the controller and then assigning them to whichever object you want. I don't know if this is best practice, though. You will need to modify the update method of the Controller.
