Hi, I have an Objects Model and a Tags Model with a M2M relationship between them. I want to update info about the tags of the object visited by the user updating it everytime the user requests an Object. Is it a crazy idea? I want to know wich tags are the most viewed by the user and wich are the most recent he has view so that I can recommend him Objects that have also such tags (objects that are related to the ones he is interested in).
This is my main idea how the models should be: =================================== class MyObject(models.Model): tags = models.ManyToManyField(Tag) etc................. class Tag(models.Model): etc............... class RelationModel(models.Model): my_object = models.ForeignKey(MyObject) tag = models.ForeignKey(Tag) times_viewed = models.PositiveIntegerField() latest_view= models.DateTimeField() Problems I see: =========== - Lets say I have 30 tags for each object, I need to create_or_update 30 rows everytime a user requests an object. That could be a bottleneck :( - The relation table can be very big: 100.000 users x 2.000 tags each user = 200.000.000 rows in the relation table!!!! I should limit it to lets say 50 tags per user and in each update overwrite the less viewed and older tags with the new ones. -> more updates on every request :S - Is this the better way to do what I want to do? Any ideas? Thank you for your help. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
