So, here’s the offending line. Note that I’m using edge rails. form\_tag verifications\_path(@user), :method =\> :post do verifications\_path(@user) returns a string like “/users/3/ verifications”. That eventually gets sent to url\_for, which expects a hash. And then it blows up. It’s especially disconcerting since the documentation shows form\_tag as accepting a string. Joe 1.

Nevermind, this was a result of me including UrlWriter into ActionView.
