So this would be the one thing I have a question about -- I want the checkbox to be checked if predicted score is not 0, otherwise unchecked. But we need to either do ```checked => true``` or ```checked => false```, because ```checked => "false"``` will still check the checkbox. We can't use ```.present?``` or ```.presence``` for this, since 0 would return true for the first and 0 for the second, and ```checked => 0``` would check the box. So what we need is something that returns a value of true for any integer value thats positive and non zero, and return false for nil, 0, or just empty string. So first I convert to an integer for whatever value, which for nil, 0, or "" should still return 0, and then check if that is > 0.

I feel like there should be a better way to do this though, I could add another function in the lines of ```nil_or_zero```, but I feel like there may be a built in way with rails do it, so let me know.
