My final code is looks like the following:
#client_route.route('/client/cat-<dir_code>/subscribe/<string:user_id>', methods=['POST'])
#only_client
#is_active_client
# #cache.cached(timeout=60)
def subscribe_abonent(user_id):
search_form = Search()
client_id = Client.query.filter_by(tele=session.get('client_phone') ,name=session.get('client_logged_in'), family=session.get('client_family')).first_or_404()
master = Abonent.query.filter_by(public_id=user_id, slug_direction=g.get('current_directory')).first_or_404()
client = Client.query.filter_by(id=client_id.id).first_or_404()
if session.get('client_is_not_subscriber'):
session.pop('client_is_not_subscriber')
session['client_is_subscriber'] = client.name + client.family + str(client.id)
socketio.emit('show_calendar', namespace='/masterCalendar-{}'.format(master.slug, master.public_id.replace('-','')))
if master.email is not None:
if master.subscribers_notifications:
date_now = datetime.now()
send_email(master.email, 'You got a new subscriber','client/newsletter/new_subscriber',master=master.name + ' ' + master.family, client=client.name + " " + client.family, sent=date_now)
#celery.task
def send_email(to, subject, template, **kwargs):
with current_app.app_context():
msg = Message(current_app.config['UBOOK_MAIL_SUBJECT_PREFIX'] + ' ' + subject,
sender=current_app.config['UBOOK_MAIL_SENDER'], recipients=[to])
msg.body = render_template(template + '.txt', **kwargs)
msg.html = render_template(template + '.html', **kwargs)
mail.send(msg)
Now everything is working fine, but celery not recognizing the task, the task runs inside the terminal just like your are sending email using Thread !!!
new_subscriber.txt:
Dear Vladimir, Here was {{master}}
You got a new subscriber:
Клиент: Sasha , Here was {{client}}
Получено: 2017-11-23 12:47:23 , Here was {{sent}}
Another thing that i forgot to mention that , if i removed the master, client and sent arguments and used delay() the code get freezed !!

I'm trying to use Paho MQTT Client and Multiprocessing to send temperature with defined interval. However, publish command is not working inside class. I've checked self.mqtt_client inside scheduler it has the Client object.
Is there anyone that can address problem for me?
Everything inside class is working except Scheduler.
def scheduler(self, topic, interval):
if interval != 0:
while True:
if topic == "temp":
print("Temperature published " + interval) #It's working.
self.mqtt_client.publish(topic, interval , 0 , False) #There is no error/output about this line

You mqtt_connect function will never return.
self.mqtt_client.loop_forever() Will block until self.mqtt_client.disconnect() is called.
You should probably be using self.mqtt_client.loop_start() which will run the client loop on it's own thread in the background. You can call self.mqtt_client.loop_stop() when you want to shut the client down.

If you define your serial port with no timeout it will get the default setting timeout=None which means when you call serial.read(x) the code will block until you read x bytes.
If you never get those x bytes your code will get stuck in there waiting forever, or at least until you receive more data on the buffer to get the total number of bytes received equal to x.
If you mix that up with threading, I'm afraid you are quite likely closing the port while you are trying to read.
You can probably fix this issue just defining a sensible read timeout on your port or changing the way you read. The general advice is to set a timeout that works for your application and read at least the maximum number of bytes you expect. Reading your code, that seems to be what you wanted to do. If so, you forgot to set the timeout.
If you have a reason not to set a timeout or you want to keep your reading routine as it is, you can make your code work if you cancel reading before closing. You can do that with serial.cancel_read()
I am new to Python and very much a rookie. I am trying to write a program that uses the requests module to make a request to the Dark Sky API for a weather forecast, and then uses smtplib to send that forecast in an email to myself. I have truncated my code to only show the relevant parts. I have been unable to find any answers so far so I apologise if this is a duplicate. The below code will print the function to the console without any issues, but when I try to assign it to the "body" variable and email it, the email is blank. Or if I use str(ds.current)) the email just has "none" as the body text.
How can I make it work so that the body text of the email contains the forecast that has been requested from the API? Many thanks in advance, and sorry for any rookie errors.
import requests
import json
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
class Darksky():
r = requests.get('https://api.darksky.net/forecast/e01635ccacb5548e3d1fa40403bbb3a5/-45.0312,168.6626?units=ca')
wx_json = r.json()
def __init__(self, source):
self.source = source
print "\n", "-" * 20, source, "-" * 20, "\n"
def current(self):
def summary():
return "CURRENT WEATHER:"
x = self.wx_json['currently']['summary']
return x
# I have tried using print instead of return but that did not work either.
def temp():
return "TEMPERATURE:"
y = self.wx_json['currently']['temperature']
return y
summary()
temp()
ds = Darksky("DARKSKY WX")
fromaddr = "watsonthevirtualbutler#gmail.com"
toaddr = "matt#peakpixel.nz"
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "YOUR DAILY WEATHER, SIR."
body = ds.current()
# This is where I am trying to save the function result as a string that can be emailed.
# I have tried using "str(ds.current())" but that just returns "none".
print body
msg.attach(MIMEText(body, 'plain'))
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, "virtualbutler")
text = msg.as_string()
msg = "CAN YOU HEAR ME, SIR?"
server.sendmail(fromaddr, toaddr, text)
server.quit()
Your summary() and temp() has two return operators, while only one return is acceptable. If you want your_function() to return few values, you can do something like: return {"first_parameter": "first_value", "second_parameter": "second_value"} and then call each value as your_function()["first_parameter"] or your_function()["second_parameter"]
Try following code and let me know the result:
class Darksky():
r = requests.get('https://api.darksky.net/forecast/e01635ccacb5548e3d1fa40403bbb3a5/-45.0312,168.6626?units=ca')

def current(self):
return "CURRENT WEATHER: {0}. TEMPERATURE: {1}".format(self.wx_json['currently']['summary'], self.wx_json['currently']['temperature'])
ds = Darksky("DARKSKY WX")
body = ds.current()
There is a lot of questions with same subject, but no replies, especially about receiving. There exist example how to send attachment, but I didn't found how to receive it.
Is there any solution on python for receiving attachments? I even agree to change my SOAP tool from suds to anything that will works.
Thank you in advance.
I solved it with suds.

File.size = fin_idx - start_idx

soap_body = '<SOAP-ENV:Envelope' + self.find_substring(reply.message, '<SOAP-ENV:Envelope', '</SOAP-ENV:Envelope>') + '</SOAP-ENV:Envelope>'
ctx = plugins.message.received(reply=soap_body)
soap_body = ctx.reply
if SoapClient.options.retxml:
answer = soap_body
else:
answer = SoapClient.succeeded(binding, soap_body)
dict = {}
self.FieldsToDict(answer.model.instance, dict)
return {u'body': answer, u'Files': Files}
Here we extract some low level of suds, being able to fix any field in envelope. Then, after reply was got, we parse all boundaries and receive as many files, as we got.
I have this simple code: basically a tool to send some commands to cmd, and display the output from cmd in a QTextEdit.
Basically, it works.
The only problem that I have is that each time I click on send (with or without a new command), the text is appended but strange blank lines appears at the end of the QTextEdit. Even when i clear the "console", still have these lines.
Maybe it has something to do with the way I call the process, I don't know hence the need for help.

You probably want to use the string.rstrip() function instead of string.strip()
if you change
self.console.append(str(self.process.readAllStandardOutput()))
to
self.console.append(str([self.process.readAllStandardOutput()]))
you can see what is going on, hope this helps
def appendText(self):
if self.check1.isChecked():

you have to remove the last line after else and just type pass
this way no new empty lines will be appended
def appendText(self):

TEXT1 = "Dir" + ' ' + str(self.variable.text())
else:
pass
