Arguments: transform: callable to transform each item to text, it gets an item as argument and must return a string-like representation of the item. By default, it calls `~django.utils.force_str` on each item. filter: callable to filter, limit or order the QuerySet, it gets the `ManyRelatedManager` as first argument and must return a filtered QuerySet. By default, it returns `all()` separator: separator string to join the items with. default: ``", "`` linkify_item: callable, arguments to reverse() or `True` to wrap items in a ```` tag.

For example, when displaying a list of friends with their full name:: # models.py class Person(models.Model): first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) friends = models.ManyToManyField(Person) is_active = models.BooleanField(default=True) @property def name(self): return '{} {}'.format(self.first_name, self.last_name) # tables.py class PersonTable(tables.Table): name = tables.Column(order_by=("last_name", "first_name")) friends = tables.ManyToManyColumn(transform=lambda user: u.name) If only the active friends should be displayed, you can use the `filter` argument:: friends = tables.ManyToManyColumn(filter=lambda qs: qs.filter(is_active=True)) N, cs|ddtj|i||dur||_|dur||_||_d}t|r,t|d}nt|tt fr9t|d}n|dur@t}|durUt dd|j dii||_ dSdS) N orderableF)url) reverse_argsTattrsa) setdefaultsuper__init__ transformfilter separatorcallabledict isinstancetupler rget linkify_item)selfrrrrargskwargs link_kwargs __class__r^/var/www/ideatree/venv/lib/python3.10/site-packages/django_tables2/columns/manytomanycolumn.pyr2s"   "zManyToManyColumn.__init__cCst|S)zh Transform is applied to each item of the list of objects from the ManyToMany relation. r)robjrrr%rIszManyToManyColumn.transformcCs|S)z Filter is called on the ManyRelatedManager to allow ordering, filtering or limiting on the set of related objects. )all)rqsrrr%rOszManyToManyColumn.filtercCsXg}||D]}t||}t|dr|j||d}||qtt|j|S)Nr)contentrecord) rrrhasattrrappendrrjoin)rvalueitemsitemr)rrr%renderVs  zManyToManyColumn.rendercKst|tjr |di|SdS)Nr)rrManyToManyField)clsfieldr!rrr% from_fieldas zManyToManyColumn.from_field)NNr N) __name__ __module__ __qualname____doc__rrrr1 classmethodr5 __classcell__rrr#r%r s) r N) django.dbrdjango.utils.encodingrdjango.utils.htmlrrbaserr r registerr rrrr%s
