title: Peewee union two tables without join
body: <pre><code>class Table1(Model):
      name = CharField()
  class Table2(Model):
      name = CharField()
      table1_id = ForeignKeyField(Table1)
  </code></pre>
  
  <p>You need a query that combines these two tables:</p>
  
  <pre><code>select Table1.id, Table1.name, Table2.table1_id from Table1, Table1 where Table2.table1_id == Table1.id
  </code></pre>
