Django relations between Models

What I currently have in my models is this: 

class Project(models.Model):
    project_name = models.CharField(max_length=255, unique=True, blank=False)
    def __str__(self):
        return str(self.project_name)


class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)  
    role = models.CharField(choices=ROLE_CHOICES, max_length=255, default='Agent')

Now my question is: Users should be able to have multiple Projects - so I obviously can't use a OneToOne-Field in the Profile-Model.

Later I want to use it for example to just show a user news which are only related to the projects he participates in.

What would be the best strategy to make this possible? Any input is highly appreciated.

Use ManyToMany on project.

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)  
    role = models.CharField(choices=ROLE_CHOICES, max_length=255, default='Agent')
    project = models.ManyToManyField(Project)

This way one profile can have as many project as he/she wants

On your view you can use this field to filter based on project
