Another quick gotcha that I just discovered. If you have a model that has a time on the backend, be careful which tags you use. In my case, I have an app that is outside UTC:
On my form, when editing the model, everything appears fine. But when you check out the difference in these two tags, you’ll see that text_field renders the incorrect time, whereas datetime_select renders the correct time.
I put in a defect ticket for this here. Hopefully the Rails team will be able to knock that out quick.
