  <pre><code>bin/cake bake migration CreateProducts name:string description:text created modified
  </code></pre>
  
  <p>this command create file and when use below command it creates database table in phpmyadmin:</p>
  
  <pre><code>bin/cake migrations migrate
  </code></pre>
  
  <p>But I want to update table with add one column in it..so when I try to update database table it create another migration file ..each time when I want to update database table..these seems weired..because I want to update single table..
