Also I am using mysql connector. Is this an issue?
db = mysql.connector.connect(
#credentials
host="itookurjob.mysql.pythonanywhere-services.com",
user="itookurjob",
password="__", #set in database
database="hwcc_tally" #i tried to avoid common mistake of prefixing with $
)
Not sure what else I can do.
My folder structure:
hwcc
├── __pycache__
│ └── run.cpython-310.pyc
├── run.py
└── static
├── index.html
└── styles.css
In flask I use this:
@app.route("/")
def display_table():
cursor = db.cursor()
cursor.execute("SELECT * FROM hwcc_entrants")
results = cursor.fetchall() # Fetch all rows
col_names = [desc[0] for desc in cursor.description]
return render_template("index.html", data=results,col_names=col_names) # Pass data to template
@app.route("/process_data",methods=["POST"])
def send_data():
entries = int(request.form["input_entries"]) #linked to html name attribute
#did we actually forget the insert statement syntax :lol
sql = "INSERT INTO hwcc_entrants (total_entrants) VALUES (%s)" #note entrant_count is taken from above var
# Execute SQL statement
with db.cursor() as cursor:
cursor = db.cursor()
cursor.execute(sql, (entries,)) #adding comma to introduce a tuple?
db.commit()
# # Close connections - with takes care of cursor.close
# cursor.close()
## intentionally removed this to keep db connections open otherwise unexpected results?
# db.close()
return redirect("/") #redirection after submission
Here is my html snippet:
<!DOCTYPE html>
<html>
<head>
<title>Enter Data</title>
<link rel="stylesheet" href="{{ url_for('static', filename='styles.css') }}">
</head>
<body>
<p>Inserts record to database for tallying number of entrants every week</p>
<!-- Form for inserting records -->
<form action="process_data" method="POST">
<button type="submit">Insert record</button>
<!-- The name attribute is passed onto Jinja within send_data function -->
<input name="input_entries" type="number">
</form>
<!-- This is my database table -->
<table>
<thead>
<tr>
{% for column in col_names %}
<th>{{ column }}</th>
{% endfor %}
</tr>
</thead>
<tbody>
{% for row in data %}
<tr>
{% for item in row %}
<td>{{ item }}</td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
</body>
</html>
