💡 Hint

Common Mistakes

Using a list instead of a set for response_model_exclude.

Passing a string without quotes or as a variable name.

Misspelling the field name.

The response_model_exclude parameter expects a set of field names to exclude. Using {'password'} correctly excludes the password field.

Common Mistakes

Using a list instead of a set for response_model_include.

Passing a string without quotes or as a variable name.

Including fields not defined in the model.

response_model_include expects a set of field names to include. Using {'username', 'email'} correctly includes only those fields.

💡 Hint

Common Mistakes

Using a list instead of a set.

Passing a string without quotes.

Using parentheses which create a string, not a tuple or set.

response_model_exclude requires a set of field names. Using {'email'} correctly excludes the email field.

FastAPI

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

class User(BaseModel):
    username: str
    email: str
    password: str

@app.get("/user", response_model=User, response_model_include=[1], response_model_exclude=[2])

Common Mistakes

Using lists instead of sets.

Including fields not needed.

Confusing include and exclude sets.

To include only username, use {'username'} for response_model_include. To exclude password, use {'password'} for response_model_exclude.

Fill all three blanks to include username and email, exclude password, and return the user data.

FastAPI

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()
