I used the above code. I want to use the create method to persist a record to db, but it throws an error. I am new to rails3. I have checked my syntax, didn't find any error. Am I missing something?

I have figured it out by myself. In subscription model, I used a send column.

Send may be a keyword of rails so it threw an error. After I changed it to some other word e.g. 'subscribe', then it works fine.

(I have encounted this issue when used a column named "type" too)

Did you override your initialize in your Subscription model?
