So I'm using a column in my database to serialize a hash of extra
data about an object. Stuff I'd want when displaying, but not
anything else I care to have structured access to in my DB. I
recently started storing an URL in field, so I decided I'd better
change the column type from string (which it probably should never
have been) to text.
I did so with a standard migration
def self.up
change_column :my_table, :related_data, :text
end
Looking in my schema.db file, I see:
t.text "related_data", :limit => 255
I think I know how to fix it, but want some reinforcement I'm on
the right track before I spend the time. Looks like what I really
need is:
def self.up
add_column :my_table, :new_related_data, :text
# copy data from related_data to new_related_data
remove_column :my_table, :related_data
rename_column :my_table, :new_related_data, :related_data
end
yes?
Or just...
change_column :my_table, :related_data, :text, :limit => 123456789
# or whatever you think is large enough

I think that the limit can be 2048 as I recall that is the max for a
URL. I can't find a reference to back that up at the moment, but I
think that this is what the sitemap specification (see Google) allows,
too.
