Forum: RForum Getting an error on adding migration

Hello ,

  I am a ROR beginner. I did scaffolding and made a table called
register with a field "name". Now when I tried to add one more column
using add migration and then rake db:migrate, the command is executing
successfully but new columns are not coming in the table

  Thank you for the reply :-) . I will explain . I did scaffolding and 
made a table called register with a field "name" . After that as I 
wanted to add more fields in that table I did the add migration command 
which is "ruby script/generate migration AddPasswordToRegister 
password:varchar" and also the rake db:migrate command. But when I run 
it on the browser the new column (password) which has been added is not 
showing there. it is only showing the "name" field which i got when i 
did scaffolding. I am able to add many columns through migration but 
they are not displaying on the browser. When I checked the files in my 
system , I could find out that new migration files are being created in 
the db/migration folder but nothing is being created in the views.

 hope this would help you to understand my problem now

Sam Migration is to database and Scaffold is for view purpose.

On running migration a column may be added to yr DB. Check that first if 
there is a column the work of migration is that and its done.

Scaffold is responsible to generate CRUD skeleton code. Since you did 
scaffold before adding the new field password thats not reflected.
