title: How to get Column reference from declarative table in SqlAlchemy?
body: <p>I use the <em>declarative</em> style to define my tables with SQLAlchemy.</p>
  
  <pre><code>Base = declarative_base()
  
  class MyTable(Base):
      id = Column('someone_put_a_strange_for_id', Integer)
  </code></pre>
  
  <p>Now, when I define <strong>ForeignKey</strong> in the class, I need to use</p>
  
  <pre><code>MyTable.__table__.c.someone_put_a_strange_for_id
  </code></pre>
  
  <p>to refer to this <em>id</em> Column attribute. Is there any way I can use</p>
  
  <pre><code>MyTable.id.some_magic
  </code></pre>
  
  <p>to get this Column attribute?</p>
