I’m trying to write my first app in rails (no better way to learn than  
to do). I did my first migration to create the initial table, which  
worked fine. I generated the scaffold and added one new line item (a  
workout) to the database no problem.

I then wanted to add some more fields to the database table, so I built  
another migration…

class AddFields \< ActiveRecord::Migration  
def self.up  
add\_column :workouts, :weight, :text  
add\_column :workouts,:maxheart, :integer  
add\_column :workouts,:minheart, :integer  
add\_column :workouts,:avgheart, :integer  
add\_column :workouts,:timehour, :integer  
add\_column :workouts,:timemin, :integer  
add\_column :workouts,:timesec, :integer  
end

def self.down  
remove\_column :workouts,:weight  
remove\_column :workouts,:maxheart  
remove\_column :workouts,:minheart  
remove\_column :workouts,:avgheart  
remove\_column :workouts,:timehour  
remove\_column :workouts,:timemin  
remove\_column :workouts,:timesec  
end  
end

and ran rake, which worked fine. But when I go to the ‘new’ action,  
those fields do NOT show up. They are in fact in the database, because I  
logged into mysql and looked, and they show up in the list view as empty  
fields.

Am I missing a step to get them to show?

If you actually generated the scaffold with

script/generate scaffold …

then you will have to edit the files to include the new fields.  
That’s actually the point of scaffolding…it’s just a place to get  
started. Have a look in views/ to see which files you  
will need to modify.

Ah! Duh…gotcha. So if I were using dynamic scaffolding it would have  
worked, but once I generated the actual files… makes sense. Thanks!
