I am trying to build an app that has a page where I input an id and run a query on that and show results. Code I have so far is below.
I keep a werkzeug error:
BuildError: ('show_entries', {}, None)
app.py
import cx_Oracle
# Run the query to display the results
@app.route('/matcher/<int:account_id>', methods=['GET', 'POST'])
def show_entries(account_id):
sql = """SELECT item1,
item2,
item3,
item4,
item5,
item6
FROM TABLE
WHERE account_id = ?"""
c = g.db.cursor()
c.execute(sql, account_id)
You are receiving that error because your show_entries
method is expecting an account_id
argument, but your url_for
call isn't supplying one.
It looks like you're trying to have the show_entries
method take the account_id
argument as a GET value in your form, but as part of the URL (not a GET parameter) in the method definition, so you have a mismatch.
You can give the account_id
variable in the method definition a default value and also check for its presence in the GET parameters:
@app.route('/matcher/', methods=['GET', 'POST'])
@app.route('/matcher/<int:account_id>', methods=['GET', 'POST'])
def show_entries(account_id=0):
if request.method == 'GET' and not account_id:
account_id = request.args.get('account_id', 0)
...
Docs: url_for , request.args.get .
The addition that makes this work is here. Everything else in my original code is fine, even if not optimal.
c.execute(sql, account_id=account_id)
