Hello every body I´m new in rails and I need to know the following: - I have 4 *.csvfiles which are generated automatically by an application made it in delphi. - I need to take those files (.csv) and migrate them o save them (its info not them as a entire file) into a DB modeled on MySQl or SQL Server (automatically and preferably to MySQL) - I want to do an application who let me do this(that generate for me the tables and their implicit relations, and also save its contents) --------- Is there any way for managing directly from rails my application on delphi? I need some ideas for reading automatically the info. held it in the *.csv files and later save it to a DB (SQL server or MySQL). Then I wanna build an Rails´s app for managing the data stored/held into the DB. Some of those *.csv files could generate more than a table. I´ve four of them and I think I will have 11 tables at least. Thanks. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Are the tables schemas already *known*, just the tables themselves have not necessarily been created yet? In that case it''s just a simple matter of creating the tables if needed, slurping up the data, and sticking it into the database. (Trivial, and I should know, that''s mostly what I did at the job before last, which I quit partly because it was so BORING!) Since you say:> Some of those *.csv files could generate more than a table. I´ve four of > them and I think I will have 11 tables at least.it sounds like you may need to hold them in some intermediate objects, so not quite so trivial. Or do you mean that the content of these data files will dictate what the tables'' schemas should be? That''s a little more challenging. Off the top of my head you could read them in, create a database migration, migrate, then dump the data into the tables. Apart from ActiveRecord being handy, you wouldn''t even need Rails. -Dave -- LOOKING FOR WORK! What: Ruby (on/off Rails), Python, other modern languages.
