How to show all fields of model in admin page?

Question

here is the models page

In this picture, only the title shows up on here, I used:

 def __unicode__(self):
        return self.title;  

Answer 1

Every solution found here raises an error like this

The value of 'list_display[n]' must not be a ManyToManyField.

If the model contains a Many to Many field.

A possible solution that worked for me is:

list_display = [field.name for field in MyModel._meta.get_fields() if not x.many_to_many]
