Hello Amit,
Miguel Grinberg has written some useful tutorials on REST with Flask:

https://blog.miguelgrinberg.com/post/designing-a-restful-api-with-python-and-flask

there are links to two other tutorials. I found them very useful.
Hopefully, they will be useful to you too.

Subject: [Flask] Prevent saving of temp file during upload
Message-ID: <CAG=NiTY6GB4y98jn17ijHNPghVMyrkAdDZ0KgQqnYWN1FOVbvw@mail.gmail.com>

Hello All!

I've been looking for a way to prevent Flask/Request/FileStorage from
saving uploaded files on the disk and instead digest them with my own code.

Most (all?) results from Google simply tell to just do file.read(), but
that still results in a file saved in a temp directory and read from the
disk. I'm trying to avoid that, because the uploaded file needs to actually
be passed on to an underlying storage (LI Ambry), and can be hundreds of
gigabytes in size. It's not viable to store the file first and then pass it
on to the final storage service :(

I see that both Request and FileStorage classes can accept a "shallow"
parameter, but there's virtually no information on what it actually does,
or how to use it :(

Any help or suggestions would be greatly appreciated!

I'm guessing the goal is to get access to wsgi directly and prevent Request
and/or FileStorage from eating up the uploaded data...

P.S. Python newbie here, so apologies for possibly stupid questions :)

Subject: [Flask] Flask with Json Format
Message-ID: <CADDeBdWbFrLJ5zZPSWMP7myQohamN2gMnPOje1nUOdzPXYeC1Q@mail.gmail.com>

Hi All,
            Is there is any good tutorial/handson which will return the
data in Json format with examples like handlers which will fetch the real
time data.

I went through mentioned below tutorial
https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world
and currently I hardcoded the the Json data and returned to browser
now I need to return some real time data from
microblog/virtualenv-15.1.0/app/views.py

instead of hardcoded.

from flask import Flask,jsonify,json
from app import app
@app.route("/getEmployeeList")
def getEmployeeList():
    try:
        # Initialize a employee list
        employeeList = []
        # create a instances for filling up employee list
        for i in range(0,2):
            empDict = {
                'firstName': 'Roy',
                'lastName': 'Augustine'}
        employeeList.append(empDict)
        # convert to json data
        jsonStr = json.dumps(employeeList)
    except Exception ,e:
        print str(e)
    return jsonify(Employees=jsonStr)


and can you please help me for interface as well to lower backed layer.

Thanks

Subject: [Flask] DB Updates based on events
Message-ID: <CA+8umNUr72m21HUNx6bYv8BtVGW1hbeOWjh-ndE3RhoqtZ+RwQ@mail.gmail.com>

Hi,

I've created a view for stripe payments. Now upon success I need to update
my local database table. I am new to Flask so I have no clue how to do it
plus there are multiple ways I've tried and couldn't make it work. It is
like sub model attached to parent model with ForeignKey, What I need is to
update Package field in database upon I commit to child table
automatically. Following is my view and Model:

View:
@app.route('/yearlyrecurring')
def subscriptions_yearly_recurring():
    if not user_authorized():
        return redirect('/')

    key = stripe_keys['publishable_key']
    charge_all = stripe.Charge.list(limit=895)
    charge_dic = {}
    charge_list = []
    for charge_data in charge_all:
        charge_dic['Amount'] = "$" + str(float(charge_data.amount) / 100) +
" " + charge_data.currency.upper()
        charge_dic['Description'] = charge_data.description
        charge_dic['Name'] = charge_data.receipt_email
        charge_dic['Date'] =
str(datetime.datetime.fromtimestamp(charge_data.created))
        charge_list.append(charge_dic)
        charge_dic = {}

    return render_template('/profile/packages/annualrecurring.html',
**locals())


@app.route('/yearlychargedrec', methods=['POST'])
def yearly_charged_rec():

    if not user_authorized():
        return redirect('/')
    # customer
    stripe_token = request.form['stripeToken']
    email = request.form['stripeEmail']

    customer = stripe.Customer.create(
        email=email,
        source=request.form['stripeToken']
    )
    try:
        subscription = stripe.Subscription.create(
            customer=customer.id,
            plan="yearlyrec",
        )

    except stripe.error.CardError as e:
        # The card has been declined
        body = e.json_body
        err = body['error']
    return render_template('/profile/charge/monthlycharge.html')

My Model:

#Parent model

Student(db.Model):
......
package = relationship('Package', backref=backref('student"))
......
Packages(db.Model):

id = db.Column(db.Integer, primary_key=True, autoincrement=True)
    student_id = db.Column(db.Integer, ForeignKey('student_profile.id'))
    stripe_id = db.Column(db.String(45))
    student_email = db.Column(db.String(20))
    subscription_date = db.Column(db.DateTime, default=today)
    expiry_date = db.Column(db.DateTime, default=deadline)
    is_active = db.Column(db.Boolean, default=True)
    planname = relationship('Plan', backref=backref('package'))
    package_price = db.Column(db.Integer)
    coupon = db.Column(db.String(12))


    def __init__(self, id,
        student_id,
        stripe_id,
        student_email,
        subscription_date,
        expiry_date,
        is_active,
        planname,

Message-ID: <CA+8umNVncFGDX8N=zb_+=0L7ZvDf466F84eMsS5oMbd79Cnriw@mail.gmail.com>

I am having trouble with updating database tables from flask view.
Following is the view:

@app.route('/yearlychargedrec', methods=['GET', 'POST'])
def yearly_charged_rec():

    if not user_authorized():
        return redirect('/')
    # customer
    if request.method == 'POST':
        stripe_token = request.form['stripeToken']
        email = request.form['stripeEmail']

        customer = stripe.Customer.create(
            email=email,
            source=request.form['stripeToken']
        )
        try:
            subscription = stripe.Subscription.create(
                customer=customer.id,
                plan="yearlyrec",
            )

            package = Package(

                is_active=True,
                planname = 'yearlyrec',

            )
            db.session.add(package)
            db.session.commit()

        except stripe.error.CardError as e:
            # The card has been declined
            body = e.json_body
            err = body['error']

    return render_template('/profile/charge/monthlycharge.html')

Error I get is:

AttributeError: 'str' object has no attribute 'session'

Please advise.

Where does your db variable come from?

I am having trouble understanding how to manipulate database in Flask from
views. Rest of topics I was able to cover pretty quickly in Flask. I am a
new user so help is much appreciated.

Following is the link for details guys from one of my post at
stackoverflow. Thank a lot for help guys.

Just a clarity that the stackoverflow post has nothing to do with the
question. That problem I got solved. I just gave the reference to show you
how my models are defined.
Thanks

The error message you showed us most probably references the db variable.
Is db a global variable in the same file? Or is it imported from another
module? Can you check its value?

It is imported from another file.

But how exactly is it imported? Where is it assigned a value? The
problem seems to be that db is not an instance of a Database object,
but rather it has been assigned a string. For example:

$ python3
Python 3.5.2 (default, Nov 17 2016, 17:05:23)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> db = "foobar"
>>> db.session
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'session'

I think I found it. I really am sorry that I was not clearly lay down
source code reflecting the issue and thanks for the patience. In __init__
file the previous developer has something like below:

#File1
login_manager = LoginManager()
login_manager.init_app(app)

db = {
    'users': {
        "test": ("test", "test")
    },
    'session': {}
}
app.config['DEBUG'] = True
app.config['WTF_CSRF_ENABLED'] = False
app.secret_key =
'\x06\x94\xcf\xaf\xaeB&\xd1s\xa8ZGU\xd2J\xf3\xd6\x12(\xbd\xf5\xc3\x858'

db = 'db'

Then in another file he declared the database like below:

#File 2
import os
import oursql
from flask import Flask

app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://'+ 'root' \
+ ':' + 'test123'+'@'\
+ 'localhost' + '/students'
db = SQLAlchemy(app)
def get_connection():
    return oursql.connect(host='localhost', port='3306',
                          user='root',
                          passwd='test123', db='students')

Now when I need to create any model and need to add tables I do this in
shell:

from file2 import db
from somemodelfile import MyNewModel
db.create_all()

That is how it adds tables. But still I am confuse that why it is not
letting me update fields.

Except above code there is no representation of data related to how db
needs to be handled. All the file inside project call database from file1
but in shell I can't use create_db(). When in shell I do like below:

>>>from file1 import db
>>>db
'db' #This is the output

You mean I should delete following line?

db='db'

Alright. It seems I scanned over your examples too hastily. In "File
#1" you have:

    db = {
        'users': {
            "test": ("test", "test")
        },
        'session': {}
    }

Then in "File #2" you have:

    db = SQLAlchemy(app)

So, in two places you declare a variable called db. The variable db in
File #1 is a dict. The variable db in File #2 is an instance of
SQLAlchemy. I'd probably rename one of the two at least so it's clear
which is which.

The error you see is because you're using the db dict from File #1 and
trying to access an attribute called "session" (which I assume is a
method that exists on the db instance of SQLAlchemy). I think what you
want to do is import db from File #2 not File #1. I see the the db
dict also contains a key called session. If that's what you really
want to use then the correct syntax is db["session"] not db.session.

Have you taken a look at the Flask-SQLAlchemy quickstart?

Your Database should be an instance of the SQLAlchemy class, not a dictionary.

I imported both in shell and with I printed the one from file2 shows
SQlAlchemy instance of DB. So what I did in my views that I left file1.db
as it is in my views just to make sure if it is applied to anything (3900
lines of code in views) it won't be disturbed. Then I imported file2 db
like below.

from file2 import db as dbase

Now it is saving models perfectly. I am really thankful to you guys for
help. This group rocks.

Hi,

I am having trouble saving Stripe json objects in Flask Database. Just need
to save customer.id and expiry date from the view below:

@app.route('/yearlychargedrec', methods=['GET', 'POST'])
def yearly_charged_rec():
    if not user_authorized():
        return redirect('/')
    if request.method == 'POST':
        stripe_token = request.form['stripeToken']
        email = request.form['stripeEmail']
        customer = stripe.Customer.create(
            email=email,
            source=request.form['stripeToken']
        )
        try:
            subscription = stripe.Subscription.create(
                customer=customer.id,
                plan="yearlyrec",
            )

            package = Package(
                student_email=request.form['stripeEmail'],
                is_active=True,
                package_type='yearlyrec'
            )
            dbase.session.add(package)
            dbase.session.commit()
        except stripe.error.CardError as e:
            body = e.json_body
            err = body['error']

    return render_template('/profile/charge/monthlycharge.html')

I don't see an expiry date below. I don't see where you try to save
the customer id. What do you mean by "trouble"? Do you mean you've
encountered an error, or that you don't know how and you'd like us to
do the work for you? The former we can help with. The latter is
probably beyond the scope of this list.

See stripe_token variable above.

subscription is unused.

See email variable above.

body and err are unused. This error is ignored.

monthlycharge.html within a yearly charge handler?

I have a Package model where I am trying to update fields below but for
expiry and due date I don't know how to implement. Objective is to retrieve
due date and expiry dates from stripe subscriptions.

class Package(db.Model):
    __tablename__ = 'package'

    id = db.Column(db.Integer, primary_key=True, autoincrement=True)
    student_id = db.Column(db.Integer, ForeignKey('student_profile.id'))
    stripe_id = db.Column(db.String(45))
    student_email = db.Column(db.String(20))
    subscription_date = db.Column(db.DateTime, default=today)
    expiry_date = db.Column(db.DateTime, default=deadline)
    expiry_date = db.Column(db.DateTime, default=deadline)
    is_active = db.Column(db.Boolean, default=True)
    package_type = db.Column(db.String(45), default='NOPACKAGE')

    package_price = db.Column(db.Integer)
    coupon = db.Column(db.String(12))

    def __init__(self, **kwargs):
        for key, value in kwargs.items():
            setattr(self, key, value)

May I make a modest request: that we try to trim our replies to just 
what's absolutely necessary for context?

   https://en.wikipedia.org/wiki/Posting_style#Trimming_and_reformatting

It takes just a couple of seconds to select and delete the parts you 
don't need, even on a mobile device.

I know that mail clients like Outlook, Apple Mail, and mobiles actively 
hide enclosed replies (and are thus part of the problem), but anyone who 
gets the digest version of the Flask mailing list will see this

multiplied by however messages are in the digest. This impacts the 
signal-to-noise ratio of the digest dramatically.

Thanks for your consideration.

Subject: [Flask] Flask-SQLAlchemy 2.2 released
Message-ID: <CADtfqL7HQqeuK9c6x=SkDWa-HPj4-EPsyNvK=nekdtDLQZk-UQ@mail.gmail.com>

After a long wait, we've released Flask-SQLAlchemy 2.2 with essential bug
fixes from the last few years. Sorry for the long wait!
https://github.com/mitsuhiko/flask-sqlalchemy/releases/tag/2.2

Install or upgrade with pip:

    pip install -U Flask-SQLAlchemy

Changelog:

- Minimum SQLAlchemy version is 0.8 due to use of ``sqlalchemy.inspect``.
- Added support for custom ``query_class`` and ``model_class`` as args
  to the ``SQLAlchemy`` constructor. (`#328`_)
- Allow listening to SQLAlchemy events on ``db.session``. (`#364`_)
- Allow ``__bind_key__`` on abstract models. (`#373`_)
- Allow ``SQLALCHEMY_ECHO`` to be a string. (`#409`_)
- Warn when ``SQLALCHEMY_DATABASE_URI`` is not set. (`#443`_)
- Don't let pagination generate invalid page numbers. (`#460`_)
- Drop support of Flask < 0.10. This means the db session is always tied to
  the app context and its teardown event. (`#461`_)
- Tablename generation logic no longer accesses class properties unless they
  are ``declared_attr``. (`#467`_)

We are still working towards larger changes in a 3.0 release, and would
appreciate any help, big or small. Whether it's triaging issues, updating
and improving the docs, finding bugs, or squashing bugs, everything helps!

Finally, if you want to, please retweet this to spread the word to more
developers:

Again, thank you for your continued support and patience!

Agreed! I do this as a habit nowadays.

It would be nice if there were settings to automatically remove (or rather,
not add) quoted text. I know desktop Gmail has a setting, though the mobile
apps don't.

FYI, the Inbox app includes it by default but doesn't show it to you: you
have to start typing, close the draft, and then open it again to backspace.

I haven't used many other services; perhaps someone else could share
details on those?

Subject: [Flask] JSON is always pretty
Message-ID: <CANc-5UzcWNgmbHtsTaoSywv6C926p04qsheZnwK_OjSP8ChLqA@mail.gmail.com>

I just started using Flask (v 0.12 in a Conda Python 2.7 environment)
as a tool to implement a RESTful server. So far, it looks great. I'm
just debugging things and working with small output, so it's not a
huge deal just now, but no matter what I do, flask.jsonify() seems to
always pretty print the returned JSON. I've been running my
application like this:

FLASK_DEBUG=1 FLASK_APP=map.py flask run

then in map.py, I tweak the config parameters like so:

app = Flask(__name__)

DEBUG = os.environ.get("FLASK_DEBUG") == "1"
app.config.update(DEBUG=DEBUG, JSON_PRETTYPRINT_REGULAR=DEBUG)

Even if I leave FLASK_DEBUG off the command line or explicitly set it
to "0", the JSON comes out formatted. Thinking I might have misread
the documentation of JSON_PRETTYPRINT_REGULAR, I changed the update
call to

app.config.update(DEBUG=DEBUG, JSON_PRETTYPRINT_REGULAR=not DEBUG)

but that had no effect. The output is still pretty.

Am I supposed to be unable to explicitly override JSON pretty printing
at the level of flask.jsonify()? Do I need to drop down a level to
flask.json.dumps() (where it also seems to be uncontrollable, but
always condensed)?

Thanks,

Skip Montanaro

Looks like you using the wrong config name? "JSONIFY" not "JSON". The
following works for me.

app.config['JSONIFY_PRETTYPRINT_REGULAR'] = False

Duh, thanks. In my defense, you have to admit that config name is a
real mouthful. A few characters more-or-less are easy to miss. ;-)
