Question

I have created a new migration:

class AddSignatureToUser < ActiveRecord::Migration
  def self.up
    add_column :users, :signature, :text
  end

  def self.down
    remove_column :users, :signature
  end
end

Now my usertable has a new column called signature.
On my edit page I wrote:

<h1>Editing user</h1>
<% form_for(@user) do |f| %>



  <%= f.error_messages %>
  <div class="form-wrapper">
    <p>
      <label for="email">Email</label>
      <%= f.text_field :email %>
    </p>
    <p>
      <label for="user_signature">Signature</label>
      <%= f.text_area(:signature, :value => @user.signature) %>
    </p>
    <div class="form-submit">
      <%= f.submit 'Update', :class => "form-submit-button" %>
    </div>

  </div>


<% end %>

But this won’t work.
In my controller I always get nil as value for signature. Any ideas why?

  def update
    @user = User.find(params[:id])

    respond_to do |format|
      if @user.update_attributes(params[:user])
        puts @user.signature #always nil
        flash[:notice] = 'User was successfully updated.'
        format.html { redirect_to(@user) }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @user.errors, :status => :unprocessable_entity }
      end
    end
  end

Okay, I found my error!
In my user model, I had

attr_accessible :login, :email, :password, :password_confirmation

I added :signature and now it’s working!

attr_accessible :login, :email, :password, :password_confirmation, :signature
