Happy new year ! 

I am currently having some issues in the development of a web application, and it may be because of some misuse of Flask. If you could help me on this it will be awesome ! 

As the application is still in development, the datas and the source code changes quite frequently. I noticed that after changing the templates I had to re-launch the server to make the changes occur. That was not a problem at first. However as my projected grew it began to happen that changes didn't took place, even after re-launching the server. I first thought it was a cache problem but the issues carries on over different web navigators (I tested Firefox and Chrome) and even in private navigation of after manually cleaning the cache. 
I discovered that this problem doesn't only concern templates but all the static files too. 
Is that a known problem ? I found no mention of it on the Internet but maybe someone already encountered it here. 
Of course it could have no link with Flask itself, but for now I have no idea where else does it could come from. 


As a side question, I wonder what is the recommended method to pass arguments to javascript from flask. Currently I am doing it with a <script> field in my template, but it doesn't feel good. Is there a better way to do that ? 

Thank you for your attention, 

Felix

If think the configuration setting you are looking for is TEMPLATES_AUTO_RELOAD.
This option defaults to True when DEBUG mode is enabled:

I don't have an answer yet for this question. The best I found so far is:
https://stackoverflow.com/questions/10314800/flask-url-for-urls-in-javascript

But at the moment I'm stick with what you do (ie. managing my javascript code as
a jinja template)

I already tried the debug mode, it doesn't solve my problem. Note that the problem is the persistence of datas even through reboots of the server, not only when actualizing.

Without more details (code, input, output, errors, etc) your question

Subject: [Flask] How to truely asynchronize a Flask application
Message-ID: <CAJznosMabqn5T7-9wqaYUiqu2RHCuTAeM_Xiu2106U-kes6cjg@mail.gmail.com>

Dear


I developed a Flask web application, which while testing,
did exactly what I expected from it.

But now that we want to access this application (which performs
long-lasting queries to the database)
with multiple users, I realize that the Flask, he way I have used it,works
as a blocking server.

As I am new to both Python and Flask development,
I wonder if someone guide me on how I could
make this application run in an a-synchronize way?
Meaning: multiple (read a lot of) users served at the same time.


I thank you in advance


Christos

Hi Christos,



Is your application hitting any errors/bottlenecks? What do you mean by
"works as a blocking server"?


The framework is production ready and you should be able to run it with
multiple users.


Or you're load testing it and the system cannot really cope? Could you
please clarify?

Dear


First of all, thank you for the quick reply.

I mean that it seems that the request object is shared between different
users.
Some of our endpoints are accessing big data sets so it takes a long(er)
time before a response is generated.

If in the mean time other users want to access the same (or other)
endpoints,
they are put in a waiting list until that first request got responded.

So I want this application to run so that multiple (read a lot of) users
are served at the same time.


Yours Sincerely


Christos

First of all, thank you for the quick reply.

Ok, I will try out a few of them.

Do you have any preferences between them?

Gunicorn is plug&play with Flask so you can go ahead.

Are you sure it's not a cache problem? I had the same issue a few weeks ago
and disabling the cache via chrome developer tools did the trick.

Apparently it was, it seems solved after I install a dedicated application to empty the cache. It was not obvious at all because setting manually Firefox to disable the cache is not enough. So it seems finally Flask is not responsible for this at all: that's just a common "bug" (it might be intended but that's weird) for Chrome and Firefox. 

Thank you !

You may also want to set SEND_FILE_MAX_AGE_DEFAULT to 0 when you are
makings regular changes to your static files.

Subject: [Flask] User uploads file naming conflicts
Message-ID: <CAO6+pgKoZ5TbORg3QKtK8659=BXc6goDJCLwN0W8-0nc0b7CXg@mail.gmail.com>

Hello everyone,

My desire is to have a simple upload form for images, but I am not
sure how to manage naming conflicts.

My start point was http://flask.pocoo.org/docs/0.12/patterns/fileuploads/

Which then gets me to here:
[code: Python]

MEDIA_DIR = my media directory
input_name = name field from file input form

img = request.files[input_name]
img_name = secure_filename(img.filename)
path = os.path.join(MEDIA_DIR, img_name)
img.save(path)

[/code]

I have no problem submitting new images with this,
werkzeug.FileStorage is the suggested object to use, but it seems the
save() method fails silently. Trying this myself by uploading new
image with the same name, the file was not uploaded. Not very friendly
to newcomers, but sensible by Flask 'batteries not included'
standards.

I understand this is because the method catches the error:

[code: Python]
# https://github.com/pallets/werkzeug/blob/master/werkzeug/datastructures.py
try:
     shutil.copyfileobj(self.stream, dst, buffer_size)
[/code]

My question is, what is best practice for managing naming conflicts?
Should I iterate existing files and check for matching? Is there a
useful numerical system I could use to append filenames?

Thanks in advance,

Message-ID: <CABC5zqj6mrVZHqT39fB3UOTkP608fsTN_66vQE8QtXMcKRff6A@mail.gmail.com>

So the first step to debuging this would be to try the copy step yourself
(i.e. bypass the builtin code from the img.save function and execute the
copyfileobj call yourself).

import shutil
outfile = open(path,'wb')
shutil.copyfileobj(img.stream, outfile)
outfile.close()


and see if you get any errors.

>From what I can tell, copyfileobj should not fail if there's an existing
file, but overwrite the file instead. My testing concurs, so there's some
other issue at hand here.

You might also check that your files are being written with the right
permissions and owner/group.

As for naming conflicts, I always like to datestamp files, or generate a
random nonce. Another option is to hash the file (md5 or sha1), and use the
first N digits of the hash as the filename (if the filename and original
file name are stored in a DB somewhere), or prepend/append them to the
basename of the file. This way if someone uploads the identical file, it
would overwrite, but the filename wouldn't change.

I find iterating to be time consuming and excessive. I've also not found
any elegant way to do so other than globbing, which isn't perfect (such as
if file name ends with numbers, or when you hit more than single digit
increment counter). I did however just get a result from googling, the
seqfile package (https://pypi.python.org/pypi/seqfile), which seems to do
what you want. Haven't used it, so results may vary.

Message-ID: <31cb5b49-33e1-47f9-99ff-f935aa61e6dc@Spark>

Hello, everyone.

I?m writing a website with Flask. I use Flask-Security to do?authentication and use Nginx + Gunicorn to deploy it.

And I find a problem that Flask-Security can?t work with Gunicorn with multiple workers.

If the worker number is one, I can login normally. If the worker number of Gunicorn is greater than one or there is more than one Gunicorn servers behind Nginx, There are three situations will happen:

1. It will login normally;
2. It will redirect to login page again;
3. It will redirect to the page protected by Flask-Security with unlogined status.

After I expose Gunicorn?server to public, It remains.

Hi ??,



It seems that somehow your application is storing information that's
only available to the Gunicorn instance that the client connects to.


Have you tested forcing the same user connecting always to the same
Gunicorn instance? That should probably work.


Where are you storing the session information?

Thanks for your reply.

I have no idea where to store the session. I have no configuration about session. Need i use Flask-Session?

How do you determine that a user is authenticated? I suspect that
currently your application stores information individually on each
of the Gunicorn workers processes memory so it is different on
each of them.


I found these links that can help you understand what can be wrong
on our app:


http://stackoverflow.com/questions/27240278/sharing-memory-in-gunicorn

http://stackoverflow.com/questions/34172964/persistent-db-connection-in-django-wsgi-application


You could either re-architect your app or look at doing something like
this, mentioned on the first link:

Message-ID: <1a29cdd2-a7c9-8926-1610-ca00417b0f9b@googlemail.com>

I'm trying to modify the flaskr tutorial to make a full blown wiki using 
ckeditor and its mostly working ok - bar the search.
There is a field 'description' which is meant to contain words and 
phrases for searching.
I wish to search a text field in the database but cannot get anything 
other than the following to parse:

     searchstring=request.form['searchstr'];
     cur = g.db.execute('select * from entries where description like 
(?) order by id desc',(searchstring,))

any attempts to add %'s etc seem lead to failure. I can build the sql 
string myself but would like to make it safe.
Any ideas how to do this?

I think the issue is it's not seeing the % as the wildcard. If you add the
wildcard chars to the search string before you supply it to execute, it
works.

There's a few Stack Overflow questions on this same topic:
http://stackoverflow.com/questions/3105249/python-sqlite-parameter-substitution-with-wildcards-in-like

Try:

searchstring = '%'+request.form['searchstr']+'%'

cur = g.db.execute('select * from entries where description like (?) order
by id desc',(searchstring,))

The only change is adding the '%' surrounding your search string.

Thanks Anthony! A good 'Doh' moment there. Spent so much time trying to 
get the parameter substitution bent to my will it looks like I was even 
trying to throw 'C' at it in the end!

Glad to help!

Personally, it looks like a weird implementation issue. % and _ are clearly
constructs in SQLite (and SQL in general), so the parsing should be able to
handle wildcards near the substitution character, but it apparently can't.

The sheer number of people asking that question on Stack Overflow makes me
feel like it's something that should be considered a bug, but it's
apparently been that way for a while, so I doubt that's gonna change.

Good luck with Flask!

Message-ID: <8689DFAB-4F23-4838-BD87-AC61C2C6AC68@yahoo.com>

Hi All,

I'm trying to integrate redis with flask's session. My motivation are redis being more secure than the standard cookie implementation, and slightly better overall performance.

I posted an issue on flasks official github repository, regarding the exact details:

- https://github.com/pallets/flask/issues/2150

However, the issue was closed, and I was recommended this email list.  If someone has implemented redis with flask's session, or have ideas, would you mind assisting?


Thank you,

Have you checked the offical Flask plugin, Flask-Session?

It has support for Redis, among other backends. Can be found here:
https://pythonhosted.org/Flask-Session/

That being said, have you tested the redis server outside your application?
Are you sure you can connect to it?

It's hard to summarize so much background.  My application has an automated build via vagrant for local development.  This vagrant environment works as intended on the chrome browser:

- https://github.com/jeff1evesque/machine-learning/pull/2867#issuecomment-272431783

The docker environment (currently) is for automated unit tests, handled by Travis CI.  But, the build is failing with redis, when integrated with the flask session:

- https://travis-ci.org/jeff1evesque/machine-learning/builds/191619024#L3803

I spoke to @notdaniel in #pocoo, and he's been really helpful.  He helped me with the working vagrant environment.  But, last night he told me to try to explicitly define redis strict session, similar to the way my application uses it, in other places.

My application uses redis in other contexts, like generating model, then serializing it into redis, so it can be used for future predictions, when queried from redis, the. unserialized.  I have unit tests that have been integrated into Travis CI, which tests this.  This feature has been in place for some time, so I know redis works within my application for other needs.


Thank you,

hey jeffrey,

if the situation the way you describe it on that github ticket is still
accurate, then i think the problem is that when you initialize the
session_interface, you are not passing your -- already connected --
redis instance and so RedisSessionInterface.__init__() attches it's own
default one and the defaults might not be right when you're running in a
virtualized environment or networked containers.

so instead of:
app.session_interface = RedisSessionInterface()

do:
app.session_interface = RedisSessionInterface(redis=yourRedis)

where "yourRedis" is the one you know is working for your models "in
other contexts" already.

and you should be fine.

cheers,
ub

Hi,

I've made available the Docker environment and CI/CD pipeline I used
in a side project. Originally this project used Vagrant and Ansible.
Docker Flask Starterkit is my answer to the question, "How would this
work with Docker?". I'm not sure how much of an active project this is
or will become. For now I just hope this could be helpful as a crib
sheet to someone.

Hello friends!,

Is there something simmilar to "return abort()" but that you can raise ?
Basically, raise an exception that in fact is a response which flask
understands and returns ?

Thank You

Message-ID: <CANOLXgwfUNAyBH8_RZ1i2B0-9+6B=Qa=BeZYf12iy-6jLMdV8w@mail.gmail.com>

Hi Flask team,

We would like to share our extension `flask-ponywhoosh` in
http://flask.pocoo.org/extensions/.
We wrote it for a project some time ago using flask successfully. This
package provides full-text search
on databases using Whoosh and Pony ORM, flask provides the front-end, and
it easily pluggable.
The repository is http://github.com/compiteing/flask-ponywhoosh and it is
available in pypi.

Flask-PonyWhoosh <https://pypi.python.org/pypi/flask-ponywhoosh/1.0>
A search engine for flask using pony orm and whoosh.
Author: jonaprieto <http://github.com/jonaprieto> and piperod

PyPI Page: Package Documentation <http://pythonhosted.org/flask-ponywhoosh/>
On Github: compiteing/flask-ponywhoosh
<http://github.com/compiteing/flask-ponywhoosh>

Let me know any suggestion, hint or improvement or a feedback

Thanks in advance,

Jonathan Prieto-Cubides,
Felipe Rodriguez.

Message-ID: <59EF1234-BB95-4F99-9591-7FC7D16241F6@gmail.com>

Hi,
I often use the ipython shell in Flask-script when developing to validate code snippets and debug my flask models. Overall it works great.

Only one problem I've found with this workflow is that if you change some line of code, it will not 'autoreload' the code or model classes. So I find I do a lot of shutting down the shell and restarting it:

I've tried using the ipython autoreload magic function - which does not help

Wondering if anyone on this thread has experienced this and knows a work around

Thanks

Hi Graeme,

I'm on my cell, so not very good for typing.  This is the flask unit testing method I use:

Granted, I'd look at the repositories master branch, since minor things may have changed.  Also, if you find my approach is bad, please correct me - input is always great.

You cannot reliably reload code in the Python shell. Restart your shell to
use updated code.

Hi Flask Users and Developers,

In the period between July and early September, I have been working on a 
kind of Content Management System (CMS) for Flask, however, I've just 
changed jobs, hence I found my self struggling to allocate any time to 
make some progress in the project.

Today, I am publishing the source code of the CMS project  (codename 
'Canella CMS') in the hope that it would gain momentum and thrive on the 
hands of the Flask community.

'Canella CMS' is a prototypical content management system, it has full 
support for creating, editing, and managing pages. Pages, along with 
their metadata, can be managed in an intuitive,  user-friendly WYSIWYG 
interface by an authorized user. Aside of this 'Canella CMS' has the 
following features fully implemented:
* Beautifully designed administrative interface based on Flask-Admin, 
with a custom layout using Material Design and bootstrap in the frontend.
* Multiple Page types.
* Seamless and arbitrary page nesting
* Comprehensive page metadata and slugging support
* An interface to manage static content (such as images, documents, and 
audio files ...etc)
* Versioning and revision history support for page content using 
SQLAlchemy-Continuum
* A fully functional blogging system, including categories and post tags.
* A Reusable user-comments system (currently implemented for blog posts)
* A Powerful inline-editing system for pages and blog posts
* A Custom WYSIWYG interface  for creating dynamic HTML forms and 
publishing them as pages and exporting them as a CSV file.
* User accounts and user profile using flask security
* A Powerful editable settings system, for users to edit several types 
of settings in a friendly manor within their browsers
* A Simple, Material Design inspired user-facing web site design.

Simplicity and customizability are the overriding principles of 'Canella 
CMS' design, I am trying to create the absolute set of
  features that make up a CMS, while leveraging the Micro-ish nature of 
Flask to leave out many optional features for the end-user to implement.

The source code of 'Canella CMS' is published on github:

https://github.com/mush42/Canella-CMS

I want to get the community's feedback on this pre-alpha version, Are 
there any critical bugs or limitations in the currently available 
features? What are the other features a CMS is required to have? and all 
sort of suggestions and ideas.

I am also looking for contributors, repository maintainers, and if the 
project is embraced by a Flask mammoth, I will be more than happy to 
transfer the ownership of the entire project to him or her if a 
potential has been realized.

Please review the source code, run a local copy of the CMS, or even 
install it on your private cloud playground, and please send us your 
feedback.

Kind Regards,
