Hi there, I have some major structure change issues with an ruby on rails application, and I'd like to ask you about how i can handle that. I will make some dummy problems for you to show what i want to reach:
1. Having a Client model with first_name and last_name should now come together as name: For the model it would be easy to have just def name first_name + ' ' + last_name end That works, but now I want to change the database this way, so we dont need the first_name and last_name anymore: I could create a migration having a name:string:index field. but after that - how can I make all the first_name and last_name applied there, and remove the first_name and last_name fields? 2. same for appointments: We had a start_datetime and an end_datetime which until now was enaugh. but now we want to change it to planned_start_time end actual_start_time (same for end time) on the migration all the old data from start_datetime should be put into both (for historical data) planned end actual times. For the future this will differ. How can I make this migrations? If I know about that later there will be some table changes, but maybe I understand the routines for that. Is there also any sql way doing it with rails? For sql itself it would be easy with INSERT..SELECT, so maybe I could generate migrations with sql code? thanks, Martin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
