Installing authlogic 3.4.3 in Rails 4.1.7 - authlogic

Question

Since yesterday I have been trying to install authlogic in a project. As I can see, all the examples and the documentation are oriented to older versions of both rails and authlogic. However, I tried to follow :
the example in the documentation
the railscast
other websites examples like: http://www.logansbailey.com/2010/10/06/how-to-setup-authlogic-in-rails-3/ (for me, the most useful tutorial until now)
I don't get authlogic working properly.
I installed the gem trough the gemfile and the bundle install order.
I generated a model user and ran the migration
$ rails generate scaffold user username:string email:string crypted_password:string password_salt:string persistence_token:string
$ rake db:migrate
I add the following line to the model user.rb:
acts_as_authentic
then, I put a link to register a new user: link_to "Register", new_user_path
I edit /app/views/users/index.html.erb to look like:
<h1>Listing users</h1>
<table>
<tr>
<th>Username</th>
<th>Email</th>
<th></th>
<th></th>
<th></th>
</tr>
<% #users.each do |user| %>
<tr>
<td><%= user.username %></td>
<td><%= user.email %></td>
<td><%= link_to 'Show', user %></td>
<td><%= link_to 'Edit', edit_user_path(user) %></td>
<td><%= link_to 'Destroy', user, :confirm => 'Are you sure?', :method => :delete %></td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New User', new_user_path %>
and app/views/users/_form.html.erb to look like:
<%= form_for(#user) do |f| %>
<% if #user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#user.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% #user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :username %><br />
<%= f.text_field :username %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.text_field :email %>
</div>
<div class="field">
<%= f.label :password %><br />
<%= f.password_field :password %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Now, when I try to register an user, I get two errors:
-Password is too short (minimum is 4 characters)
-Password confirmation is too short (minimum is 4 characters)
I have put longer passwords but it doesn't work.
Any help?
Thank you

Just based on the error messages without seeing the users controller, it appears that password and password_confirmation are not being passed to the user model. This may be a Rails 4 preventing mass assignment issue. To allow this, in the create method in the users controller, you can say:
#user = User.new(user_params)
and then define the user_params method:
def user_params
params.require(:user).permit(:password, :password_confirmation, :name, :email)
end
