python - How to check the type of a many-to-many-field in django? -

How can you test several-to-many-fields in the DNS?

I wanted to do this like this:

  import digenous field .__ class__ == django.db.models.fields.related.ManyRelatedManager  

This is not work, because the class has many relayed managers not found. But if I do field .__ class __ then the output is django.db.models.fields.related.ManyRelatedManager

this refers to a class Why does not it seem and how can I bring it to work?

Many thanks for your help.

If you already have field examples, then you can do just that:

< If you have only the related manager example, you can reverse the field to see the example:

ifense (field, multipleTomainField): pass / luggage P> >

  & gt; & Gt; & Gt; Print FM & lt; Category 'django.db.models.fields.related.ManyRelatedManager' & gt; & Gt; & Gt; & Gt; Print fm.instance._meta.get_field_by_name ('fieldnamehere') (& lt; django.db.models.fields.related.ForeignKey: fieldnamehere & gt; any, true, false)  

< P> it is only tested on Django 1.5
