People that don't know Rails are going to think that you're making pointed critiques of the framework, when in fact you appear to be repeatedly citing examples of people going through extra effort to use the interfaces Rails provides for directly using SQL instead of ActiveRecord's finders.
I'm not offering a "pointed critique of Rails" ([edit] although your framing it as such seems to encourage downvotes into the negatives). I'm demonstrating how the use of non-parameterized queries source of error that has repeatedly resulted in SQL injection issues in ActiveRecord. I have provided three different examples:
- In the first, the API design itself made it non-obvious/easy to directly concatenate strings while -- at a glance -- appearing to be correct.
- In the second, the API's implementation resulted in SQL injection because :limit and :offset arguments were not correctly escaped.
- In the third, the API's documentation and recommended usage (in 2004) encouraged users to use constructs that appeared to provide defense against SQL injection, but in reality, did not.
