I've lost count of how many times I have tried to do something in Rails which was trivial in every other framework I have ever worked with; struggled; gone to #rubyonrails or a mailing list and asked for advice; and had people tell me that I was "fighting the framework". I understand the benefit of not having to make every single decision from the ground up when you're getting started on a project, but sometimes I worry that working with rails is actually warping my thought patterns to fit its myopic vision of how web apps "should" work.

To phrase it differently: I feel comfortable with a framework or community forcing me to change how I achieve some higher-level goal. But when that convention prevents me from doing something, period, I start to worry.
