Type error init missing 1 required positional argument ondelete

What is a type error?

A type error is an error that occurs when a value is of the wrong type. For example, if you try to concatenate a string and an integer, you will get a type error. The error message will tell you that you are missing a required positional argument ondelete.

What is the difference between a type error and an AttributeError?

TypeError is raised when an operation or function is applied to an object of an inappropriate type. The associated value is a string giving details about the type mismatch.

AttributeError is raised when an attribute reference (see Attribute references) or assignment fails. (An attribute is a name defined in a class.) The associated value is often a string giving the name of the undefined attribute. But for more complicated cases, it can be an instance of AttributeError.

What causes a typeerror?

There are many causes for a TypeError, but the most common cause is when a function or method is called with the wrong number of arguments. When this happens, you will see a TypeError message telling you that init missing 1 required positional argument ondelete.

How can I fix a typeerror?

If you’re seeing a TypeError when you run your code, it means that Python is unable to determine the type of one or more variables. This can happen in a number of ways:

-You’re using the wrong data type for a parameter or variable (e.g. passing a string to a function that expects an int)
-You’re using the wrong data type for the return value of a function (e.g. returning an int from a function that expects a string)
-You’re trying to operate on two variables with different data types (e.g. adding an int and a string)

TypeErrors can be frustrating, but they’re relatively easy to fix. The first step is to identify where the error is occurring in your code. Once you’ve done that, you can try to figure out what data type you should be using instead. If you’re still stuck, feel free to ask for help on our forum.
