I am trying to get the related_name of a many-to-many-field.
The m2m-field is located betweeen the models "Group" and "Lection" and is declared in the group-model as following:
lections = models.ManyToManyField(Lection, blank=True)
The field looks like this:
<django.db.models.fields.related.ManyToManyField object at 0x012AD690>
The print of field.__dict__ is:
{'_choices': [],
'_m2m_column_cache': 'group_id',
'_m2m_name_cache': 'group',
'_m2m_reverse_column_cache': 'lection_id',
'_m2m_reverse_name_cache': 'lection',
'_unique': False,
'attname': 'lections',
'auto_created': False,
'blank': True,
'column': 'lections',
'creation_counter': 71,
'db_column': None,
'db_index': False,
'db_table': None,
'db_tablespace': '',
'default': <class django.db.models.fields.NOT_PROVIDED at 0x00FC8780>,
'editable': True,
'error_messages': {'blank': <django.utils.functional.__proxy__ object at 0x00FC
7B50>,
'invalid_choice': <django.utils.functional.__proxy__ object
at 0x00FC7A50>,
'null': <django.utils.functional.__proxy__ object at 0x00FC7
A70>},
'help_text': <django.utils.functional.__proxy__ object at 0x012AD6F0>,
'm2m_column_name': <function _curried at 0x012A88F0>,
'm2m_db_table': <function _curried at 0x012A8AF0>,
'm2m_field_name': <function _curried at 0x012A8970>,
'm2m_reverse_field_name': <function _curried at 0x012A89B0>,
'm2m_reverse_name': <function _curried at 0x012A8930>,
'max_length': None,
'name': 'lections',
'null': False,
'primary_key': False,
'rel': <django.db.models.fields.related.ManyToManyRel object at 0x012AD6B0>,
'related': <RelatedObject: mymodel:group related to lections>,
'related_query_name': <function _curried at 0x012A8670>,
'serialize': True,
'unique_for_date': None,
'unique_for_month': None,
'unique_for_year': None,
'validators': [],
'verbose_name': 'lections'}
Now the field should be accessed via a lection-instance. So this is done by lection.group_set
But i need to access it dynamically, so there is the need to get the related_name attribute from somewhere.
Here in the documentation, there is a note that it is possible to access ManyToManyField.related_name, but this doesn't work for my somehow..
Help would be a lot appreciated.
Thanks in advance.
