Hi all,
the initial startup up my app is pretty slow, since I'm seeding a large products table and that's OK. Yet, on the subsequent starts of the app, the startup should be fast.
I wonder what might be the fastest way to check if a table / model already exists.
I tested:
products = Product.find(:all)
if products.empty?
...
which is of course pretty slow (nearly the same speed as the initial seed...).
product = Product.find(:first)
if product
...
does not accelerate much.
if Product.count == 0
...
is much faster. Still, is there a better way?
I experimented with http://docs.rhomobile.com/en/5.1.1/api/Database#misTableExist:
db = new Rho::Database(Rho::Application.databaseFilePath("local"), "local")
db.isTableExist("Product")
yet, it always returns false and the "new Rho::Database" documentation states "Do not use predefined partition names: app, user, local".
Which is the best way to check if a table exists in the local database?
Thanks in advance for any hints!

So, I just got on with:
if Product.count == 0
...
end
If anyone has a hint on how to connect to the local database and use isTableExist(STRING tableName), let me know!
