Django IN query as a string result - invalid literal for int() with base 10
- by bmelton
Trying to query a 'Favorites' model to get a list of items a user has favorited, and then querying against a different model to get the objects back from that query to present to the template, but I'm getting an error: "invalid literal for int() with base 10"
Looking over all of the other instances of that error, I couldn't find any in which the asker actually wanted to work with a comma separated list of integers, so I'm kind of at a loss.
Model
class Favorite(models.Model):
# key should be the model name, id is the model.id, and user is the User object.
key = models.CharField(max_length=255, unique=True)
val = models.IntegerField(default=0)
user = models.ForeignKey(User)
class Admin:
list_display = ('key', 'id', 'user')
View
def index(request):
favorites = Favorite.objects.filter(key='blog', user=request.user.pk)
values = ""
for favorite in favorites:
values += "%s," % favorite.val
#values = "[%s]" % values
blogs = Blog.objects.filter(pk__in=values)
return render_to_response('favorite/index.html',
{
"favorites" : favorites,
"blogs" : blogs,
"values" : values,
},
context_instance=RequestContext(request)
)
