How Do I Pass A Parameter into A Get Request to A Flask Blueprint Python App?
Question
I have a flask/blueprint app that works with hard-coded or all() GET requests. This is the code in api.py :
from flask import Blueprint
from ..extensions import db
from ..models.users import Users
api = Blueprint('api', __name__)
@api.route('/user/<name>')
def get_user(email):
users = Users.query.first()
return {'users': users.email}
The above code works and doing GET http://127.0.0.1:5000/user/anythingHere in Postman returns:
{
"users": "test@example.com"
}
Which is correct and corresponds with my database. But when I modify the code in api.py to look like this:
from flask import Blueprint
from ..extensions import db
from ..models.users import Users
api = Blueprint('api', __name__)
@api.route('/user/<name>')
def get_user(email):
users = Users.query.filter_by(email='<name>').first()
return {'users': users.email}
And in Postman run http://127.0.0.1:5000/user/test@example.com hoping that test@example.com will populate <name> in filter_by(email='<name>') , but obviously this doesn't work as indicated by the fact that I get TypeError: get_user() got an unexpected keyword argument 'name' in my terminal and this in Postman:
<!doctype html>
<html lang=en>
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or
there is an error in the application.</p>
So how do I pass the email parameter from the GET request to the get_user function?

You need to pass email into the function as email not <email> like this:
from flask import Blueprint
from ..extensions import db
from ..models.users import Users
api = Blueprint('api', __name__)
@api.route('/user/<email>')
def get_user(email):
users = Users.query.filter_by(email=email).first()
return {'users': users.email}
