You need to set the username and password in environment variables. Read about os.environ in the Python documentation if you are not familiar with that.

Sir,
How can I set User permission? Please, help me if you have avail time for me.

Thanks

@miguelgrinberg
Copy link
Owner

Permissions are not assigned directly to users. Users are assigned a "role", and the role contains the list of things that are allowed (the "permissions"). If you want to assign a role to a user, just assign it to it and save it:

my_user.role = my_role
db.session.add(my_user)
db.session.commit()

As I explained above, the user needs to be the correct role assigned so that it is allowed to post. Without that role assignment the application will not display the post form. What role is assigned to user s.paceled?

Why are you inserting your code in the insert_roles() method? You need to run this outside of that, for example in a Python console.

You need to compare the manage.py file that you are using against the one in this repository. I'm sure you have something wrong there.

Yes. I think you need to learn about classes and objects, you are missing some very important concepts in the Python language.

You are trying to set the role on a string, not on a user object.

Sir, I am facing an authentication problem with my flask app. The config code is written below

app.config['MAIL_SERVER'] = 'smtp.gmail.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USE_TLS'] = False
app.config['MAIL_USE_SSL'] = True
app.config['MAIL_USERNAME'] = os.environ.get('username')
app.config['MAIL_PASSWORD'] = os.environ.get('password')`

Further, I am calling the data from MySQL to compare it with today's date. The code is written below. I have commented the for loop as of now just debug the config error.

@app.route('/mailing', methods=['GET', 'POST'])
@is_logged_in
def mailing():
	#Create cursor
	cur = mysql.connection.cursor()

	#Get Tasks
	result = cur.execute("SELECT * FROM grades WHERE remind_date=%s", [now.strftime('%Y-%m-%d')])

	grades = cur.fetchone()

	# if str(grades['remind_date']) == now.strftime('%Y-%m-%d'):
	msg = Message('Good Morning', sender='jpisvideotest@gmail.com', recipients=['hbagla@jpischool.com'])
	mail.send(msg)
	
	# Close connection
	cur.close()
	return redirect(url_for('dashboard'))

Laravel? Are you sure you are asking in the right place? In any case, the error message sends you to a link where you can find what the problem is (it's a security feature from Gmail that you'll need to turn off).

Google mail requires authentication, it seems you are not passing username and password, or they are incorrect.

Hi, this problem is solvable.
Why set MAIL_USERNAME = None.
In this code:
(venv)$set MAIL_USERNAME = 'name example'
(venv)$set MAIL_PASSWORD = 'password example'
(venv)$pythonhello.py shell

from flask_mail import Message
from hello import mail
msg = Message('TEXT', sender = 'my1@example.com', recipients = 'my2@example.com') #not important
msg.body = 'text_body'
msg.html = 'html_body'
with app.app_context():
... mail.send(msg)
...`

SMTPSenderRefused at /info/(530, b'5.5.1 Authentication Required. Learn more at\n5.5.1.....
But look at this:

print(app.config)

and i see MAIL_USERNAME = None, MAIL_PASSWORD = None and etc.(where the hell is she? at was in 1 session cmd)
had to specify in app.config clear option without the os.environ.get('MAIL_USERNAME')
The problem many people with this error is that:
With each cmd session my set MAIL_USERNAME and etc. disappear

brain boils..
p.S
(venv)$set MAIL_USERNAME
return this:
MAIL_USERNAME environment variable not defined

Need create an environment variable(MAIL_USERNAME and etc) in System Properties!

Hi all,

I faced the same.
Environment : Windows, Python version: 3.7.4

Below are the steps i followed to fix it

1, I set the environment variables using the edit system environment variables option in control panel.
2, I checked whether they were set properly by running the below commands in cmd and they were fine.

echo %EMAIL_USER%
echo %EMAIL_PASS%

3, I checked whether i am fetching the proper data from inside the python vm by running the below commands in the interpreter
import os
os.environ.get('EMAIL_USER')
os.environ.get('EMAIL_PASS')

4, Added another check point while initializing the flask app in init.py

print(f"For SMT Mail: username:{os.environ.get('EMAIL_USER')}, password:{os.environ.get('EMAIL_PASS')} ")

5, When i run the application inside terminal from visual studio code the values were not being set properly
For SMT Mail: username:None, password:None

6, When i run the same from a cmd outside vs code the environment variables were set properly and email function worked as expected.

**For SMT Mail: username:***, password:

Further more as @RWSmax explains when you set the environment variable in cmd it applies right there and then, to that process' environment. Also when you open a new terminal or cmd it will get a copy of the current environment from it's parent so you would have to restart the process in order to get a new set of environment variables.

Its basically was about setting the environment variables properly and also wrt how you are setting the environment variables. At the end Step 4 would give you the verdict.

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

3, I checked whether i am fetching the proper data from inside the python vm by running the below commands in the interpreter import os os.environ.get('EMAIL_USER') os.environ.get('EMAIL_PASS')

4, Added another check point while initializing the flask app in init.py

print(f"For SMT Mail: username:{os.environ.get('EMAIL_USER')}, password:{os.environ.get('EMAIL_PASS')} ")

5, When i run the application inside terminal from visual studio code the values were not being set properly For SMT Mail: username:None, password:None

6, When i run the same from a cmd outside vs code the environment variables were set properly and email function worked as expected.

**For SMT Mail: username:***, password:

Further more as @RWSmax explains when you set the environment variable in cmd it applies right there and then, to that process' environment. Also when you open a new terminal or cmd it will get a copy of the current environment from it's parent so you would have to restart the process in order to get a new set of environment variables.

Its basically was about setting the environment variables properly and also wrt how you are setting the environment variables. At the end Step 4 would give you the verdict.

This really really helped me. Thank you very much. spent so many hours but could not find the answer. finally got it. I have gone step by step and set the variables into environment. Closed the vs code terminal and started using in CMD. ran the command and it worked.
I will write the whole answer with my screenshots and what I did.

Hi all,

I faced the same. Environment : Windows, Python version: 3.7.4

Below are the steps i followed to fix it

1, I set the environment variables using the edit system environment variables option in control panel. 2, I checked whether they were set properly by running the below commands in cmd and they were fine.

echo %EMAIL_USER% echo %EMAIL_PASS%

3, I checked whether i am fetching the proper data from inside the python vm by running the below commands in the interpreter import os os.environ.get('EMAIL_USER') os.environ.get('EMAIL_PASS')

4, Added another check point while initializing the flask app in init.py

print(f"For SMT Mail: username:{os.environ.get('EMAIL_USER')}, password:{os.environ.get('EMAIL_PASS')} ")

5, When i run the application inside terminal from visual studio code the values were not being set properly For SMT Mail: username:None, password:None

6, When i run the same from a cmd outside vs code the environment variables were set properly and email function worked as expected.

**For SMT Mail: username:***, password:

whoever is reading, highly recommended to follow the steps above mentioned by @KathiravanBalasubramanian. I did the same and changed somethings and it worked.
Note: I was making projects in Django (not in flask) but it will work I think
My steps:

  1. First I added my Gmail ID and password to environment variable.

  1. (Also allowed "Less secure app access" in Gmail account)

  2. Changed my settings.py to this
    ## for account email varification

import os
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = os.environ.get('EMAIL_USER')
EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_PASS')`

  1. In my emails.py file (I have made separate file for this)

## Email varification for account

def send_account_activation_email(email, email_token):
subject = 'Account varificaion email'
email_from = settings.EMAIL_HOST_USER

  1. This problem occurred into VS CODE terminal. so I closed it and tried to run into CMD. Performed above steps (mentioned by @KathiravanBalasubramanian) to check whether my EMAIL ID and PASSWORD are set properly or not. And in CMD I could see the correct email id and password.

  2. After step 4 was confirmed, I ran the project and it worked. I hope it helps.

# return s.dumps({'confirm': self.id}).decode('utf-8')

def confirm(self, token):
s = Serializer(current_app.config['SECRET_KEY'])
# def generate_confirmation(self):
# s = TimedSerializer(current_app.config['SECRET_KEY'], 'confirmation')
# return s.dumps(self.id)

# def check_confirmation(self, token, max_age=3600):
#     s = TimedSerializer(current_app.config['SECRET_KEY'])
    # s = TimedSerializer(current_app.secret_key, 'confirmation')
    
    try:
        data = s.loads(token.encode('utf-8'))
    except:
        return False
    if data.get('confirm') != self.id:
        return False
    self.confirmed = True
    db.session.add(self)
    return True
The above lines of code gives me confirmation link invalid or expired, please explain to me how I can solve it.
