I am trying to store a long text (in my case a raw rss feed, but could just as well be a long blog post or similar) to a MySql database.
I have a migration with:
change_column :contents, :description, :longtext
But this gives a schema.rb with:
t.text "description", :limit => 2147483647
When the limit should in fact have been set to 4294967295.
Why does Rails impose an upper limit which is half of what should be possible?
