Hello
i have been working with api along with proteus. i could work with proteus but the condition is that i must have to set config.set\_xmlrpc(‘[http://admin:12345678@localhost:8000/health/](http://admin:12345678@localhost:8000/health/)’) in every request . that increases the delay.. is there any workaround where i could reduce the response time

There is a bug opened ([issue7783](https://bugs.tryton.org/issue7783)) about this slowness when using proteus in xmlrpc mode, which is related to login/password validation which is done with hash.
I have some code to authenticate with session cookie that I could share (but proper resolution of issue7783 would be fine, now that python3.8 is available).
For having to call `config.set_xmlrpc()` for every request, it seems odd. Do you have some example code ?

Here is the code
```
@app.route('/login', methods=['GET'])
def login(request):
configs = config.set_xmlrpc('http://admin:12345678@localhost:8000/health/')
Module = Model.get('party.party')
# party_module, = Module.find([('name', '=', 'saif')])
party = Module.find([('emailuser', '=', 'saif.kazi76@gmail.com')])
# party_module, = Module.find([('name', '=', 'party')])
return str(party[0].api_token)
```

It looks like you are developing a Flask application with Tryton as backend. You may consider [flask-trtyon](https://pypi.org/project/flask-tryton/).

Yes for small usage. You will not be able to get all the performance of the Tryton’s ORM with proteus.

Thanks a lot for the solution i can’t find an example of how i can connect flask-tryton to postgresql. or should i use vanilla flask and connect it to postgresql

It connects using `trytond` and the configuration file defined by `TRYTON_CONFIG`.

i did give it a try using by installing flask but i am getting this error on my gnu health
```auto
Traceback (most recent call last):
File "app.py", line 6, in
tryton = Tryton(app , configure_jinja=True)

File "/usr/local/lib/python3.8/dist-packages/trytond/pool.py", line 60, in __new__
database_name = Transaction().database.name
AttributeError: 'NoneType' object has no attribute 'name'
```
here is my code
```auto
from flask import Flask
from flask_tryton import Tryton
app = Flask( __name__ )
app.config['TRYTON_CONFIG'] = '/home/gnuhealth/gnuhealth/tryton/server/config/trytond.conf'
tryton = Tryton(app , configure_jinja=True)
app.run()
```
i am not sure what i am doing wrong

You must also set the `TRYTON_DATABASE` as flask-tryton is mono-database.

i just edited my code to set database
```auto
from flask import Flask
from flask_tryton import Tryton
app = Flask( __name__ )
app.config['TRYTON_CONFIG'] = '/home/gnuhealth/gnuhealth/tryton/server/config/trytond.conf'
app.config['TRYTON_DATABASE'] = 'health'
tryton = Tryton(app , configure_jinja=True)
app.run()
```
but i am getting this error

This means that the connection to the database is not properly configured.
“root” is not an existing user on the database. Probably you rely on local user to be trusted by PosgtreSQL and usually you run `trytond` with another user than “root”.

This is no more related to flask or proteus topic.
You seem to have compatibility issue between the non-standard `calendar` module and the `vobject` library.

This seems an error due to a invalid format defined on your logging configuration.
If you disable the logging you should probably be able to runt he server.
