Checking for an item in multi-user mode (django)

Question

So, I have a ManyToManyField relationship between Item1 and Item2. On a webpage, I want to display one of two messages based on whether the two elements are connected or not. I just don’t know how to request my exact element using the template tag {% if%}.

Roughly what I'm looking for,

{% if Item1 is connected to Item2 %} Display Message1 {% else %} Display Message2 {% endif %} 

Any tips on how I will do this?

 class Profile(models.Model): user = models.OneToOneField(User) name = models.CharField(max_length=50) eventList = models.ManyToManyField(Event, blank="TRUE", null="TRUE", related_name='event_set+') def __unicode__(self): return self.name 

Answer 1

It’s still not clear to me which object you want to see if it is connected to another, but if you want to find out if the user is in a particular event, you can do it as follows:

 {% if event in user.eventList.all %} Display Message1 {% else %} Display Message2 {% endif %} 

You can use the in operator in if conditions in modern versions of django.

Hope this helps!
