Rails trying to create a user when updating user details - ruby-on-rails

Question

I'm learning rails and building an authentication system using guides from around the web and following railscasts tutorials.
I've come to a stand still at the moment and need a bit of assistance if possible.
When ever I try to edit the user profile, I get an error message which tells me that it can't create an account due to fields such as email and username already being taken.
Looking around it seems it's related to how my edit form is being submitted, but I can't solve it!
Any help would be appreciated.
Users_controller.rb
def edit
#user = User.find(params[:id])
end
def update
#user = User.find(params[:id])
if #user.update_attributes(user_params)
flash[:success] = "Profile updated"
redirect_to #user
else
render 'edit'
end
end
edit.html.erb
<%= form_for :user, url: '/users' do |f| %>
<form class="m-t" role="form" action="#">
<div class="form-group">
<%= f.label :name %>
<%= f.text_field :name, class: 'form-control', autocomplete: "off" %>
</div>
<div class="form-group">
<%= f.label :user_type %>
<%= f.select(:user_type, ['Admin', 'Technical', 'Accounts'], {}, { :class => 'form-control' }) %>
</div>
<div class="form-group">
<%= f.label :email %>
<%= f.text_field :email, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :telephone %>
<%= f.text_field :telephone, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :mobile %>
<%= f.text_field :mobile, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :user_name %>
<%= f.text_field :user_name, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :password %>
<%= f.password_field :password, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :company_admin%>
<%= f.check_box :company_admin, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :user_admin %>
<%= f.check_box :user_admin, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :emergency_contact %>
<%= f.check_box :emergency_contact, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.submit "Submit", class: "btn btn-primary block full-width m-b" %>
</div>
</form>
<% end %>

Wait I'm wrong on the validation. Just spotted it.
<%= form_for :user, url: '/users' do |f| %>
This won't use the #user object, which means rails thinks you're trying to create a user.
Switch it to
<%= form_for #user do |f| %>
Rails will also infer the correct place to post to so you won't need the url option anymore.
