i can not get why drop down menu does not work. It seems that the list is empty, but when I check it in another program, it contains information as expected. I just don't get why the dorpdown list is empty. :(
Below is my code:
@app.route("/sell", methods=["GET", "POST"])
@login_required
def sell():
"""Sell shares of stock."""
currentShList = []
sharesHist = []
#i created list of dicts below to check if drop down would work - and it did
checking=[{'sh_symbol':"checking"},{'sh_symbol':"checking2"}]
if request.method == "POST":
#extract list of shares that we owned at some point from database
sharesHist = db.execute("SELECT sh_symbol, SUM(sh_amount) FROM portfolio GROUP BY sh_symbol")
#limit list to shares that we own now
for sh in sharesHist:
if sh['SUM(sh_amount)']>0:
currentShList.append(sh['sh_symbol'])
else:
return render_template("sell.html", symbolList=currentShList)
my html page is below:
{% extends "layout.html" %}
{% block title %}
Sell shares owned
{% endblock %}
{% block main %}
<form action="/sell" method="post">
<div class="form-group">
<select class="form-control" name="symbol">
<option disabled selected value="">Symbol</option>
{% for symbol in symbolList %}
<option value={{symbol["sh_symbol"]}}>{{symbol["sh_symbol"]}}</option>
<option>{{symbol}}</option>
{% endfor %}
</select>
</div>
<div class="form-group">
<input autocomplete="off" class="form-control" min="0" name="shares" placeholder="Shares" type="number"/>
</div>
<button class="btn btn-primary" type="submit">Sell</button>
</form>
{% endblock %}
