Subject: [Flask] Read data from existing database
Message-ID: <981637e0-ea83-df32-54cc-fc49744bb95a@stud.hs-regensburg.de>

Hello everyone,

I've created a data-logger using Flask-SQLAlchemy with the following 
schematic/models:

class Phase1 with id, Urms, Irms, Prms, Qrms, cosphi
class Phase2 with id, Urms, Irms, Prms, Qrms, cosphi
class Phase3 with id, Urms, Irms, Prms, Qrms, cosphi
class PhaseTotal with id, Prms, Qrms

Attached you can find the resultant database created by the file 
logger_sqlalchemy.py.

In the second part of the project I would like to set up a webserver to 
display the newest database-data on a website.
Because there is an infinite loop in the logger file, another python 
file (webserver.py, also attached) is used to do so.

Like described on the website 
"http://flask-sqlalchemy.pocoo.org/dev/queries/#querying-records", the 
following lines should display the Urms value with id 5 on the screen 
(logger_sqlalchemy.py doesn't run at this time):

URMS_L1 = Phase1.query.filter_by(id=5).first()
print(URMS_L1.Urms)

But there is always an error "Phase1 is not defined"!
Does anybody know what's going wrong?

To link the file to the corresponding database, the following lines are 
used:

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 
'sqlite:////root/project/logger_sqlalchemy.db'
db = SQLAlchemy(app)

Maybe the link to the database is not correct? The database is in the 
same folder than the webserver file.

Many thanks,
Andreas

Hi Andreas,

You have to import Phrase1 from the file you define it.

For example:

from .models import Phrase1, Phrase2

Subject: [Flask] Access to /static (static files) when deployed with cgi
Message-ID: <4BD1D479D41CBD4AA40C77701B431C964FE2AE@COLUMBA02.user.uu.se>

Hi!

I am new to flask and have deployed a flask web application based on a flask demo-project with cgi: ScriptAlias /flaskutforskning /path/flaskutforskning/flaskutforskning.cgi in production on the linux server, deployed following instructions at http://flask.pocoo.org/docs/0.11/deploying/cgi/. Se also file tree below.

I run the development-server in Visual Studio in my PC using from runserver.py, created by the VS Python tools - Flask web project, which I guess uses WSGI. See screen images below.

The application works fine except the links to static-files are different in development in Visual Studio and in production on the linux server. See file hierarchy below.

Development-server in Visual Studio in my PC
http://localhost:PORT/static/scripts/SPAshowresult.js

In production server:
http://www.mydomain.com/flaskutforskning/flaskutforskning/static/scripts/SPAshowresult.js

Questions:

?         Does anybody have a suggestion how to find a better way to work with paths so there is the same static path in dev and production?

?         Is there a better IDE than Visual Studio for development and debugging in the code, step by step?

Thank you so much in advance.

Hi,

You should preferably make the front-end use 'static/' in any hard-coded
links. This way Flask will serve up the appropriate files. As for the IDE
you may look into PyCharm and see if it suits you.

Hi there!

What I believe you're looking for is the `static_url_path` argument to the application object. See: http://flask.pocoo.org/docs/0.11/api/#application-object

You could store this value in an environment variable or config file on your development and production system so it does not require a code change between your production and development server.

Is the app behind a proxy (IE running on localhost or some remote machine) ?
If so, you might be looking for is the ProxyFix middleware. http://werkzeug.pocoo.org/docs/0.11/contrib/fixers/#werkzeug.contrib.fixers.ProxyFix

Does that help you?

Cheers,
-Spencer

Thanks for your answer!

I will try it.

Follow up questions:

?         For me it is not fully clear if the paths are relative or absolute paths. I guess they are relative.  I also wonder what they are relative to: maybe the folder for __init__.py  and cgi-file (py-file) in /flaskutforskning<http://www.mydomain.com/flaskutforskning/flaskutforskning> or the sub folder for the view.py file in /flaskutforskning/flaskutforskning<http://www.mydomain.com/flaskutforskning/flaskutforskning>? See http://flask.pocoo.org/docs/0.11/deploying/cgi/.

?         If you have any example of the parameters and how to set them from a config file I would appreciate it a lot.

Subject: RE: Access to /static (static files) when deployed with cgi

Hi there!

What I believe you're looking for is the `static_url_path` argument to the application object. See: http://flask.pocoo.org/docs/0.11/api/#application-object

You could store this value in an environment variable or config file on your development and production system so it does not require a code change between your production and development server.

Is the app behind a proxy (IE running on localhost or some remote machine) ?
If so, you might be looking for is the ProxyFix middleware. http://werkzeug.pocoo.org/docs/0.11/contrib/fixers/#werkzeug.contrib.fixers.ProxyFix

Does that help you?

Cheers,
-Spencer

Subject: [Flask] Access to /static (static files) when deployed with cgi

Hi!

I am new to flask and have deployed a flask web application based on a flask demo-project with cgi: ScriptAlias /flaskutforskning /path/flaskutforskning/flaskutforskning.cgi in production on the linux server, deployed following instructions at http://flask.pocoo.org/docs/0.11/deploying/cgi/. Se also file tree below.

I run the development-server in Visual Studio in my PC using from runserver.py, created by the VS Python tools - Flask web project, which I guess uses WSGI. See screen images below.

The application works fine except the links to static-files are different in development in Visual Studio and in production on the linux server. See file hierarchy below.

Development-server in Visual Studio in my PC
http://localhost:PORT/static/scripts/SPAshowresult.js

In production server:
http://www.mydomain.com/flaskutforskning/flaskutforskning/static/scripts/SPAshowresult.js

Questions:

?         Does anybody have a suggestion how to find a better way to work with paths so there is the same static path in dev and production?

?         Is there a better IDE than Visual Studio for development and debugging in the code, step by step?

Thank you so much in advance.

Best regards,

There's also a CGI middleware fixer that helps handle issues introduced by CGI paths. http://werkzeug.pocoo.org/docs/0.11/contrib/fixers/<http://werkzeug.pocoo.org/docs/0.11/contrib/fixers/#werkzeug.contrib.fixers.ProxyFix>

That may be what you're looking for. I believe Flask will otherwise assume that it is the root and your links generated, such as by url_for, are root-relative by default. But if your app is not actually in the root, you run into the issue you first described.

There are a few ways of handling the problem, but I think the middleware fixers and configuration changes are ideal, compared to altering a lot of code to deal with the problem so you can keep your Dev and production roughly equal.

Hi everyone,


I have a VPS with Ubuntu 14.04.4 LTS with a public ip and a small Flask application(at the moment Flask is also the WSGI). Flask is in Debug mode, I know this isn't a good security practice but I need it as it's still under development :(

I log everything and recently there was a raise of attacks: here is a sample of the logs<https://pastebin.com/z2MK6dwi>.

Always different ip, and I've never seen this kind of attacks so I don't know if they are successful or not, my questions are:


  *   What kind of attacks are these?
  *   How can i verify if they hacked my vps?
  *   What is the best way to mitigate? Autoban for invalid requests?

Thanks in advance,


Bruno

My VPS is very essential, ssh on 22 (I know it should be changed), flask on 8000 and a webadmin panel on 10000, so nothing interesting.
I'm quite used to php vulnerabilities and sqli, but I can't read that shellcode and I was worried it could be some kind of 0day.
I can provide more data if needed.

@Christophe BAL and @David Baumgold: I have turned off debug mode, unfortunately I can't have dev and prod enviroment separate at the moment

Running such application with debug ON on a widely open server is kind of crazy.
The least you can do is to add a htaccess or something in front of your
application (that's relatively easy since your are running your application
through WSGI).
You should also think about setting up a firewall and open your development port
just to a few IP's that are known to be trusted.

Search for the "python wsgi htaccess authentication" keywords.
Example:

Subject: [Flask] New flask extension
Message-ID: <98f982ba-88bf-3eb6-3e2b-071a56eb40f6@milibris.com>

Hello,

i have created a flask extension: 
https://github.com/miLibris/flask-rest-jsonapi and i would like to know 
how to register it in the flask entension list.

This extention follows the jsonapi.org protocol and combines the 
flexibility of Flask-RESTful and the quick usage of Flask-Restless with 
a data layer concept that allow you to use any ORM or storage provider.

I have made this library because in real life project you want a 
framework to quickly create simple resource api and also a hudge 
flexibility to customize the resource. Moreover you ofter need to 
retrieve data from different data providers so the data layer system 
provides a way to interface them with a CRUD concept.

Thank you for your help.

To register it, make a pull request to the Flask website repository!?https://github.com/pallets/flask-website/blob/master/flask_website/listings/extensions.py

Hello,  

i have created a flask extension:  
https://github.com/miLibris/flask-rest-jsonapi and i would like to know  
how to register it in the flask entension list.  

This extention follows the jsonapi.org protocol and combines the  
flexibility of Flask-RESTful and the quick usage of Flask-Restless with  
a data layer concept that allow you to use any ORM or storage provider.  

I have made this library because in real life project you want a  
framework to quickly create simple resource api and also a hudge  
flexibility to customize the resource. Moreover you ofter need to  
retrieve data from different data providers so the data layer system  
provides a way to interface them with a CRUD concept.  

Thank you for your help.

Subject: [Flask] Flask restless authentication
Message-ID: <7cc423fb382691a911f3b96daa8ca182@pysecure.io>

Hi,
I'm evaluating different REST API plugins for Flask, since I need only 
very simple access to models created with SQLAlchemy I am thinking about 
flask restless, however it seems it does not provide authentication 
out-of-the-box which is also my requirement. Flask restful seems to be 
an overhead for the task but it seems to mee from my short research that 
authentication support is better. It seems there is a project at 
https://github.com/graup/flask-restless-security solving my problem with 
flask restless but I dislike idea of having another dependency in the 
project. It also may not be under active development which doesn't help 
either.

So I have 2 questions:

1. can anyone point me into some good practices or example code for 
providing authentication in case of flask restless?
2. can anyone share their experience with flask restless or flask 
restful (or any other option I am not considering due to lack of my 
knowledge) and implementation of authentication functionality for the 
API?

Have a great weekend everybody
JB

Hi JB,
Before starting implementation of authentication, you may want to read the
following:

   1. https://blog.miguelgrinberg.com/post/restful-authentication-with-flask
   2. https://blog.miguelgrinberg.com/post/oauth-authentication-with-flask
   3. https://stackoverflow.com/questions/6972999/flask-user-authentication
   4.

And of course, it never hurts to read
https://pythonspot.com/en/login-authentication-with-flask/ ;-)
Bye,
Ron.

Subject: [Flask] Error when transferring data to a template
Message-ID: <d6877357-7465-dd14-2511-09c109ef1ba8@stud.hs-regensburg.de>

Hello everyone,

I've created a data-logger using Flask-SQLAlchemy.

In the second part of the project, a webserver is set up to commit some 
of the database data to a website.
Because there is an infinite loop at the logger file, another python 
file called webserver.py (code attached) is used to do so.

The operation is planed as follows:
1. If the website is called, the login-window should appear.
      ---> This part is working so far!
2. After a successful login, the home() function in the webserver.py 
file should redirect to the show_entries() function.
3. The show_entries() function read some data from the database; in this 
case the data with id=5 (this part is working as well);
     and passes the entries to the show_entries.html template.
4. Depending on whether you are logged in or not, different data is 
shown on the website.

The login is working well, but if I press the Login button, I get an 
error from the webbrowser. Does something going wrong by
passing data to the template or is the template the problem (maybe the 
if-else-statement to be sure that the user is logged in)?

Thanks for your help!
Kind regards,
Andreas

Hey Andreas.
One mistake in your code I could spot:
There is no 'entry' variable in you template just the list 'entries'.
So you probably forgot to iterate over the list:

{% if session.logged_in %}
   {% for entry in entries %}
     <h2>{{ entry.title }}</h2>
   {% endfor %}
{% else %}
   not logged in
{% endif %}


Cheers
David
