CodePudding user response：

You can simply use errors.messages and find the error for that field.

<div >
<% form.label :first_name %>
<%= form.text_field :first_name ,class:"form-control",placeholder:"First_Name" %>
<b><%= @teacher.errors.messages[:first_name].join(", ") %></b>

There are many articles and SO post for the same. You can refer to them as well
