Is the user model defined in app/models/user.rb ?

I mean, the filename has to be "user.rb", with a lowercase "u".

yes it is defined in app/models/User.rb ?

i changed but now its showing this error

Showing app/views/users/index.html.erb where line #13 raised:

You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each

Extracted source (around line #13):

10: <th>Hobby</th> 11: </tr> 12: 13: <% @user.each do |user| %> 14: <tr> 15: <td><%=h user.name %></td> 16: <td><%=h user.age %></td>

Note you put the collection in @users, plural. The variable @user is unset and thus nil, hence the error. You need to replace @user with @users in the view.

<% for user in @users %>

<%=h [user.name](http://user.name/) %> <%=h user.age %> <%end%>
