Some forms allow submitting without filling out all required fields

[20wildmanj]

Some forms such as assessments#new allow for you to submit the form without filling everything out. When pressing enter, the form submits but creation fails, but the redirect is not to the same page, nor do you see any visual indication of which field was wrong. The input into the form is not saved as well. Many forms on Autolab suffer from this issue such as editing assessments, editing courses.

It is also unclear which fields are required and which fields are optional for most fields.

1. Check each form in Autolab to see what if they have pre-validation
2. Add pre-validation to forms
3. Investigate ways of saving input in forms, apply to forms based on if it makes sense
4. Investigate 872 and see if that issue can be resolved at the same time
