Django：在模板中动态打印查询集

Question

如何打印在“fields_i_want”中指定的列而不是在模板代码中对列名进行硬编码？

# Let's say I have this in my view: 
foo = Foo.objects.filter(some_field='bar').select('field1', 'field2', 'field3') 
fields_i_want = ['field1', 'field2'] 

# Then in the template I want to do something like this: 
<TABLE id="some_id">  
    <TBODY> 
     {% for row in some_var.foo %} 
     <tr> 
     {% for value in another_var.fields_i_want %} 
      <td>{{ row[value] }}</td> 
     {% endfor %} 
     </tr> 
     {% endfor %} 
    </TBODY> 
</TABLE> 

# Instead of doing this: 
<TABLE id="some_id">  
    <TBODY> 
     {% for row in some_var.foo %} 
     <tr> 
      <td>{{ row.field1 }}</td> 
      <td>{{ row.field2 }}</td> 
     </tr> 
     {% endfor %} 
    </TBODY> 
</TABLE>
