django-filters many to many

[sebasti...@gmail.com]

Hello,

i have installed per pip django-filters.

Models.py:

class Productinterests(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=255, default="", blank=False, null=False)

class Address(models.Model):

   productinterests = models.ManyToManyField(Productinterests,blank=True, default=0)

   lastname = models.CharField(max_length=255, default="", )
   firstname = models.CharField(max_length=255, default="", blank=True, null=True)

filters.py:

   class AddressFilter(django_filters.FilterSet):
lastname = django_filters.CharFilter(lookup_expr='icontains',label="Nachname")
firstname = django_filters.CharFilter(lookup_expr='icontains', label="Vorname")

    productinterests = django_filters.ModelMultipleChoiceFilter(to_field_name='name',queryset=Productinterests.objects.all(),
widget=forms.CheckboxSelectMultiple, label="Produktinteresse")

    class Meta:
       model = Address
       fields = ['lastname','firstname','productinterests' ]

views.py:

   def search(request):
         liste = Address.objects.all()

         address = AddressFilter(request.GET, queryset=liste)
return render(request, 'search/address_list.html', {'filter': user_filter})

Problem: Website shows in Multiselect Productinterest only as Output:

 "Productinterests object (1)" instead of name from object. How can i output name?

Regards

Hello,

now it shows on frontend the name. Problem is, that in value also string is instead id.

For example:

<label class="checkbox-inline">
                <input type="checkbox" name="productinterests" value="Test" id="id_productinterests_0"> Test
              </label>

but this must be:

<label class="checkbox-inline">
                <input type="checkbox" name="productinterests" value="0" id="id_productinterests_0"> Test
              </label>

How can i change this?

Regards

Hey,

      You can add a dunder method for your  "Productinterests" model to return the name of the object instead of the name of model.

It involves the use of '__str__()' method. You can implement it in the following way:

class Productinterests(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=255, default="", blank=False, null=False) 

    def __str__(self):

            return str(self.name)

Just add the extra function in your models, and then whenever a "Productinterests" object is called, it will be outputted as the value of its 'name' property.

Regards.

Yeah but this doesn't work. I describe IT in my Last Post why
