TypeError: __init__() missing 1 required positional argument: 'value' optionmenu code example
Example 1: TypeError: __init__() missing 1 required positional argument: 'on_delete'
categorie = models.ForeignKey(
'Categorie',
on_delete=models.CASCADE,
)
Example 2: python missing 1 required positional argument:
def your_method(self, arg1, arg2): # you must add the "self" argument in 1st position
'''
This kind of error happens when working with classes
When you create methods for a class, you must always pass self as the first argument
self designates the object in which it is called
'''
# for instance :
class Dog: # let create a class Dog
def __init__(self, color, age): # when you create a new Dog object, two parameters are required
self.color = color # here, whe use self to attach the attribute to this Dog object
self.age = age
self.bark("Woof")
def bark(self, message): # your error might come from the fact you forgot to add the self element as the first argument in, at least, one method
print(message)
'''
This is a very simple example but it stays true for every class
You have to pass self as the first argument for each method
