Subject: [Flask] Multiple backend servers with Flask
Message-ID: <CAGOUAfbJZ7kJ8GhtLrGvGBCxsQc04dOsOxGQKM=zZspHnmGm6Q@mail.gmail.com>

Hello!

I have a Flask application that has an architecture like so:

http://i.stack.imgur.com/wfVRI.png

It currently all runs on a single server, but I need to be able to scale
the application by adding in more servers. I know how I can scale the
database(by creating a cluster), I do not really care about scaling the
message queue at this point, but I can create a cluster for that too.

What I am not sure about scaling is the application itself.

My sessions are stored client side in cookies (Flask-Login), so that
shouldn't be a problem. I am using Redis for storing temporary data that
needs to be accessible from every node(application server). This data has a
lifetime of 5 minutes, so no big deal.

I am using Celery as a task queue, with RabbitMQ as the broker. This is
used for running background processes and executing tasks asynchronously.

All pages served are basically static HTML, with no AJAX or anything fancy
like that.

I've thought of setting up two application servers, have each one connect
to the same database, same RabbitMQ instance, and same Redis instance, and
set up a load balancer in front of it to forward requests to either server.
But I'm worried this might cause problems like tasks getting executed twice
by Celery; would it?

Is there a better way to scale Flask applications?

Thanks.

Scaling the app is the ~easiest way.

On celery, what is should do (haven't checked) is that it reserves a job so
other processes don't get it while 1 is working on it (and if it succeeds,
it deletes the job, and if it failes the job can be retrieved by another
process)

So you should be fine.

There shouldn't be an issue. Try running multiple celery workers. If you
are not experiencing duplication of work there then it shouldn't make a
difference when you scale it out.

Subject: [Flask] Flask - data centric with mongo; & ember?
Message-ID: <CAN2of03M5aKzv9jCWzZ0TftOHQetc0qPTmg7hJyuf=X47_ru0w@mail.gmail.com>

Hi

Just wondering if anyone can offer some good practical advice on working
with flask and mongo for a data centric app.

The base requirement is that there will be a lot of grids in the
application, sports data based (fantasy) in first version.
So was thinking of using something like ember and  ember grids
http://addepar.github.io/ember-table/#/overview . Open to opinion here that
is why I am asking.

If that was a good choice then with flask and mongo I should use
https://github.com/MongoEngine/flask-mongoengine and to connect data to
ember the rest framework http://flask-restful.readthedocs.org/en/0.3.4/

Would this be a good  stack to start with ?

I made an extension called Flask-Hashing and was hoping I could get some
input on it.

https://github.com/ThaWeatherman/flask-hashing

It is already on PyPI and has docs on Read the Docs. It does work so I
guess I'm just looking for anything else that may need to be done for it to
be an official Flask extension.

Please and thanks!

This looks reasonable to me, but what?s the benefit Flask-Hashing instead of just using the hashlib module directly?

The same as Flask-Bcrypt. User only needs 1 line to generate a hash or
check one which is common with web apps.

I wrote it more to get my feet wet with extensions.

Subject: [Flask] Allow user to sort DB output
Message-ID: <55C99BDA.5040303@bluemasters.ro>

Hello everyone,

I've built a small Flask app that basically requires a a lot of database 
interaction.
I'm almost done with it now, I just need a way for the user to sort the 
information that's received from the database (order by name, price, 
location, etc)
The problem is I'm not that good at coding yet and I'm not sure how to 
go about doing this.

I'm not going to paste my code here, to avoid clutter, so I'm going to 
use Pastebin

This is the section of code that interogates the DB: 
http://pastebin.com/W76H0TSK
And this is the template portion of the code: http://pastebin.com/BsCHiU3z

I'm looking to insert anchors, or buttons, or something, into that 
template that would allow the users to sort by (for example) pct_lucru 
and/or data_expirarii and/or denumire_med.

Any ideas for me? I'm kind of stumped.

Cheers!

Environmental variable are read through a command prompt. So if you want to
set the variable "APP_CONFIG_FILE" you would have to type the following
into a command prompt before running your program:

On Linux or Max OSX:
export APP_CONFIG_FILE = "path_to_file"

On Windows:
set APP_CONFIG_FILE = "path_to_file"

I would suggest for you to read this
<http://stackoverflow.com/questions/4906977/how-to-access-environment-variables-from-python>
to
learn how to properly access the content in the environmental variable.

Though, I believe that you're looking to load the config from a file. Then
this <http://flask.pocoo.org/docs/0.10/config/#configuring-from-files> should
clear things up.

If that's the case you really should look into an orm (e.g. SQLAlchemy).

Well, you already have an ORDER clause in your sql-query. You just need 
to build the query more dynamically (meaning: depending on user input).

You could have links in your template that look sth like this (maybe in 
the table head):

<a href="{{ url_for('rezultate', order='pct_lucru-asc') }}">PUNCT LUCRU</a>

Then in the 'rezultate'-function:

if request.args.get('order') == 'pct_lucru-asc':
     order_by = 'ORDER BY stocuri_disponibile.pct_lucru ASC'
else if request.args.get('order') == 'pct_lucru-desc':
     order_by = 'ORDER BY stocuri_disponibile.pct_lucru DESC'
else:
     order_by = 'ORDER BY stocuri_disponibile.denumire_med ASC'

query  = 'SELECT [...] LIKE ? GROUP BY denumire_med '
query += order_by
query += ' LIMIT ? OFFSET ?'

cur1 = g.db.execute(query, ...)

That would be the basic idea, pretty straight forward. Just keep in mind 
to not include sth into the query that comes directly from the user.
Also: building sql statements like this isn't really fun. An orm can 
make your life a lot easier. If you are interested in an example, I have 
a simple blog software where I do sth similar (filter blog-posts) with 
sqlalchemy:
https://github.com/davidnieder/blackboard-light/blob/master/app/query.py#L13

Probably because you import your views, before mongo has been defined.
If you change the order, that is, importing your views after defining
mongo it should work.

Hello.

I am new to Flask. Is there a good support for Jade tempting instead of
Jinja2 ? How hard would be the task to build such a new plugin that can
also add some feature specific to Jinja2 ?

I think Pyjade can be useful. Take a look:

Subject: [Flask] Session timeout/ User authentication
Message-ID: <CANL9KRLLfRvPj8b4CBAqsMn3T6WnLHsj0bCRZp+fFnVFYLxBxg@mail.gmail.com>

Hi Follow users,
I am currently using google oauth for authentication using rauth,
Flask-Login extensions. I am also using "session['permanent'] = True" to
remember the sessions for certain period when timing them out. However,
what happens is the screen does not automatically refresh to logged out
view upon session expiry and needs to be manually refreshed.

One of the methods I have seen used is to pass a session id to the the
browser and browser checks every few minutes if the session is valid and if
not, refreshes the view to logged out view. How is this workflow usually
implemented in Flask? I can pass session id when the application view is
created, however how do you about authenticating session ids.

thanks for the heads up,

cheers,
Mandar

Mandar, if you?re using Google OAuth with Flask, and you?re having trouble getting it to work, I?d love for you to check out Flask-Dance, which is a Flask extension I wrote to handle OAuth login. It?s also has a contrib module specific to Google, and the quickstart is here:?http://flask-dance.readthedocs.org/en/latest/quickstarts/google.html?There?s also a quickstart that shows how to set up a multi-user system using Flask-Login and Flask-SQLAlchemy:?http://flask-dance.readthedocs.org/en/latest/quickstarts/sqla-multiuser.html

Is that useful?

Hello Everyone,

I am using following file manager for my project.

It is very helpful for me but when I try to open .svg file, It is
returning svg code.

Here is the screen shot:

Message-ID: <CANtzURKwdSFff4Xh1Zz9cY_vuQqVJtrKOLCaKG+yWZ0Fx+k0wg@mail.gmail.com>

Hey all,

I can be pretty bad about running tests locally at times, so I wrote a
little extension to help.

It automatically runs pytest in the background when you app.run in debug
mode, beeps when there's an error, shows the results in the terminal, and
gets re-run by the reloader.

This lowers the testing barrier since you don't have to manually run them
separately (or even wait for your cloud CI tool after you push to GitHub,
which has a much longer feedback loop).

https://github.com/joeyespo/flask-pytest

Would be happy to hear what you think. If this misses the mark, what's your
current setup for writing and running tests?

Oh, good then it was only issue number one, the escaping.
Please check the jinja2 documentation about "|safe" it is specially important to do so because it implies some security considerations. You are now going to push raw content to your html.
