ruby - Rails model instance with dynamic attribute value based on relationship -

my adminuser creates survey , questions go along it. different user takes survey. survey taken multiple users. of questions in survey, need include attribute of user (example: name). adminuser create question "what did user eat?" user takes survey see "what did jane eat?".

currently, have survey model , question model. questions in survey include user's name taking survey. example, if question "what eat?" "what jan eat?"

to temporarily accomplish created method on survey model creates new questions each time new survey created. clogging database same questions 1 word difference. makes more difficult link different users' answers same question since each question instance unique.

here current survey model

survey.rb

class survey < activerecord::base   belongs_to :user   belongs_to :surveyable, :polymorphic => true   has_many :questions, :dependent => :destroy     def self.generate_for_user(survey_user)       new_survey = survey.new       new_survey.surveyable_id = survey_user.id       new_survey.surveyable_type = "user"       new_survey.user = client       new_survey.save       question.new(position: 1, tier: 1, content: "when did first become aware of #{survey_user.first_name}'s needs?", question_type: "response", survey_group: "user", survey_group_question_id: 1, choices: "", survey_id: new_survey.id).save        question.new(position: 2, tier: 1, content: "what foods #{survey_user.first_name} regularly need avoid?", question_type: "response", survey_group: "user", survey_group_question_id: 2, choices: "", survey_id: new_survey.id).save       ... , on ...  end 

here current question model

class question < activerecord::base   belongs_to :survey end 

as can see, dont think went right way.

how can create questions can have dynamic attribute based on 1 of relationships? possible?

do need attribute static placeholder , call method on question inserts dynamic name placeholder when called?

i able call

question.new(content: "what #{survey_user_name} eat?") question.new(content: "what #{survey_user_name} wear?") 

and want #{name} replaced survey owner. same question can applied many different surveys , still use specific survey owners name.

first, rename content column content_raw

then define method in question model,

def content(maybe_some_params)   content_raw.gsub(.....) end 

in case, can reuse same question record if content_raw same
