def up

create_table :activities do |t|
t.integer :user_id    # references user


t.integer :trackable_id
t.string  :trackable_type    # is polymorphic


t.string  :action    #  holds only create|update|delete - for trackable record


## optional free form (free text) activity -- make it into a table of its own? why? why not?

#  why - keeps render uniform

# why not - creates an extra record/model/table


t.text    :text      # optional - text to render

t.string  :tmpl      # optional - template key


### t.string  :params  - add parameters column - why ?? why not??


t.timestamps   # - only need created-at - supposed no changes e.g. no modified_at
