how we can show users in admin panel in django in m2m field without list comprehension-CodePudding

class Page(models.Model):
    user = models.ManyToManyField(User)
    post = models.TextField()
    post_date = models.DateField()
    def get_user(self):
        return ", ".join([str(p) for p in self.user.all()])

i add this function to get users and added in list-display my question is we use list comprehension how we can do without using list comprehension

def get_user(self):return ", ".join([str(p) for p in self.user.all()])

is there anyway to do it?

CodePudding user response：

i want to know how we can do this without list comprehension. i mean how we can do with for loop

Okay, this way:

def get_user(self):
    users = list(self.user.all())
    if len(users) == 0:
        return ""
    users_str = str(users[0])
    for user in users[1:]:
        users_str  = ", "   str(user)
    return users_str

Not pretty sure why you need it, but it's possible :)
