I'm new to flask & web dev. I want to pass output of an algorithm to template so I can show it to user. But I'm doing something wrong and don't see any output in HTML other then empty bullet points.
routes.py
from flask import Flask, request, jsonify, render_template
from image_processing import find_cross_v4
import json
app = Flask(__name__)
def run_algorithms():
return {'file_name': f.filename, 'set_min': 'hello world 1','rep_sec':'hello world 2'}
@app.route('/upload', methods=['POST'])
def upload():
f = request.files['file']
f.save("image_processing/query.jpg")
data = run_algorithms()
#jsondata = jsonify(data)
#data =json.loads(jsondata)
return render_template('results.html',data=data)
@app.route('/test',methods=['POST'])
def test():
try:
f = request.files['file']
f.save("image_processing/query.jpg")
except KeyError:
return jsonify({'error': 'File Missing'})
result = run_algorithms(f)
return jsonify(result)
if __name__ == "__main__":
app.debug = True
app.run(host='0.0.0.0')
results.html
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h1 class="logo">Results</h1>
<ul>
{% for data in data %}
<li>{{data.file_name}}</li>
<li>{{data.set_min}}</li>
<li>{{data.rep_sec}}</li>
{% endfor %}
</ul>
</body>
</html>
I hit '/test' from command line
curl --form [email protected] http://0.0.0.0:5000/test
Got below as output.
{ "file_name": "somefile.jpg", "rep_sec": "hello world 2", "set_min": "hello world 1" }

I removed 'for' statement in HTML template and it worked!
