Django manytomany 字段持有用户自动填充

Question

I am pulling data from a json file on the web, and updating it in my django database. I want to keep track of users that are associated with each team, but as soon as a user loads the page once they are added to the model. How do I avoid this?

class Team(models.Model):
    name = models.CharField(max_length=120)
    abbreviation = models.CharField(max_length=3)
    id = models.IntegerField(primary_key=True)
    link = models.CharField(max_length=120)
    wins = models.IntegerField(default=0)
    losses = models.IntegerField(default=0)
    ties = models.IntegerField(default=0)
    points = models.IntegerField(default=0)
    users = models.ManyToManyField(User)

def getTeams():
    import requests
    baseUrl = "https://statsapi.web.nhl.com/"

    # INITALIZING THE DATA IN THE DATA DICTIONARY
    r = requests.get(baseUrl + '/api/v1/teams')
    originalData = r.json()
    # i dont need the copyright, only care about the teams
    originalData = originalData["teams"]
    for team in originalData:
        id = team["id"]
        try:
            databaseTeam = Team.objects.get(id = id)
        except Exception:
            Team.objects.create(id = id)
            databaseTeam = Team.objects.get(id = id)
        databaseTeam.name = team["name"]
        databaseTeam.abbreviation = team["abbreviation"]
        databaseTeam.link = team["link"]
        databaseTeam.save()
    print("done")

@login_required
def myTeamView(request):
    t1 = Thread(target=getTeams)
    t1.start()
    return(render(request, "teams/myTeams.html", {}))

Answer 1

The user is stored on user variable inside the request, so first we need to pass it to getTeams method. Then we use the method add of Manytomany fields to append an record to it, in this case the user.

def getTeams(request):
    import requests
    baseUrl = "https://statsapi.web.nhl.com/"

    # INITALIZING THE DATA IN THE DATA DICTIONARY
    r = requests.get(baseUrl + '/api/v1/teams')
    originalData = r.json()
    # i dont need the copyright, only care about the teams
    originalData = originalData["teams"]
    for team in originalData:
        id = team["id"]
        try:
            databaseTeam = Team.objects.get(id = id)
        except Exception:
            Team.objects.create(id = id)
            databaseTeam = Team.objects.get(id = id)
        databaseTeam.name = team["name"]
        databaseTeam.abbreviation = team["abbreviation"]
        databaseTeam.link = team["link"]
        databaseTeam.save()
        databaseTeam.users.add(request.user) # after save!!
    print("done")

@login_required
def myTeamView(request):
    t1 = Thread(target=getTeams, args=(request, ))
    t1.start()
    return(render(request, "teams/myTeams.html", {}))
