class Interest(models.Model): title = models.CharField(max_length=200)

def _str_(self):
    return self.title

I have trying use str to return the title but unfortunately it return back object 1

CodePudding user response：

You need to user double underscore (__)

so it'll look like:

def __str__(self):
    return self.title

CodePudding user response：

conventions

__bar__: a way for the Python system to use names that won't conflict with user names.

_bar: a way for the programmer to indicate that the variable is private (whatever that means in Python).

__bar: this has real meaning: the interpreter replaces this name with _classname__bar as a way to ensure that the name will not overlap with a similar name in another class.

No other form of underscores have meaning in the Python world, so you should use __str__ nor _str_

class Interest(models.Model):
    title = models.CharField(max_length=200)

    def __str__(self):
        return self.title

Other examples:

__init__(), __call__(), __add__(), __new__ ...
