Problem has been updated to include progress made
I have the following code and my celery tasks kick off fine, I just don't know where I should store the async result so that I can look at it again later
#!/usr/bin/env python
"""Page views."""
from flask import render_template, request
from flask import Flask
from celerytest import add
from time import sleep
app = Flask(__name__)
async_res = []
@app.route('/', methods=['GET', 'POST'])
def run():
if request.method == 'GET':
return render_template("template.html")
else:
form = request.form
n1 = str(form.get("n1"))
n2 = str(form.get("n2"))
aysnc_res = add.delay(n1,n2)
return render_template("loading.html")
@app.route('/loading')
def check_if_complete():
if async_res.ready() == True:
return render_template("template2.html", val=async_res.get())
else:
sleep(5)
return render_template("loading.html")
if __name__ == '__main__':
app.run()
It appears that storing async_res as a global variable in my flask app causes server errors. So what's the best method of storing the result so that I can check on it in my "loading page"
I ended up being able to save the ID of my task in the session dictionary in Flask
See code below:
#!/usr/bin/env python
"""Page views."""
from flask import render_template, request
from flask import Flask
from celerytest import add
from time import sleep
app = Flask(__name__)
@app.route('/', methods=['GET', 'POST'])
def run():
if request.method == 'GET':
return render_template("template.html")
else:
form = request.form
n1 = str(form.get("n1"))
n2 = str(form.get("n2"))
aysnc_res = add.delay(n1,n2)
session['TASK_ID'] = async_res.id
return render_template("loading.html")
@app.route('/loading')
def check_if_complete():
aysnc_res = session['TASK_ID']
if async_res.ready() == True:
return render_template("template2.html", val=async_res.get())
else:
sleep(5)
return render_template("loading.html")
if __name__ == '__main__':
app.run()
