Django Simple Search on Foreign Key and Many to Many Fields -


this snippet simple django search works great doesn't support searches on foreign key or many many fields. how can search fk , m2m?

looking @ snippet, magic happens here:

def get_query(query_string, search_fields):     ...     q = q(**{"%s__icontains" % field_name: term})     ...

based on that, appears does support fk or m2m searches, have specify full path in search_fields string using double underscore __.

for example, lets had model task has foreign key project, , project has attribute name:

class task(models.model):     project = models.foreignkey(project)  class project(models.model):     name = models.charfield(max_length=500)

if wanted search through project names on task, write following:

>>> tq = get_query('<search term>',['project__name',]) >>> t = task.objects.filter(tq)
