How to get all objects by instance in django
I want all objects like SomethingModel.objects.all ().
class SometingModel(model.Model):
def get_all_objects(self):
__[what should i do?]__
return queryset
eg,
queryset = SomethingModel.objects.all()
queryset_by_instance = SomethingModel.objects.get(pk=1).get_all_objects()
queryset == queryset_by_instance <===== True {doesn't matter order}
I need this to fetch data. as
def get_filtered_data(object, object_attribute, min, max):
return object.get_all_objects().filter(object_attribute__lte=max)\
.filter(object_attribute__gte=min)

You can use __class__
to get model name and then get all objects.
In [1]: my_instance.__class__
Out[1]: app_name.models.SometingModel # returns the model
In[2]: my_instance.__class__.objects.all()
Out[2]: [..list of objects..] # returns queryset
Another option is to use _meta.model
which @Spectras also mentioned above.
In[3]: my_instance._meta.model
Out[3]: app_name.models.SometingModel # returns the model
In[4]: my_instance._meta.model.objects.all()
Out[4]: [..list of objects..] # returns queryset
Then in your models, you can do something like:
class SometingModel(model.Model):
def get_all_objects(self):
queryset = self._meta.model.objects.all()
# can use the below method also
# queryset = self.__class__.objects.all()
return queryset
