title: sqlalchemy orm column name convention
body: <p>How do I automatically map all of my fields of the forms <code>my_column</code> to corresponding columns <code>MyColumn</code> in the database?</p>
  
  <pre><code>class MyTable(Base):
      __tablename__ = 'MyTable'
      # what I have now:
      my_column_1 = Column('MyColumn1', Integer)
      # what I want: how to configure a convention mapping rule for this:
      my_column_1 = Column(Integer)
  </code></pre>
