While I've not tried hosting a Django app with them, Hostgator was
bought out by EIG and their quality & service tanked.  EIG has a
reputation for buying out excellent hosting businesses, killing the
quality by putting too many customers on shared machines, raising
prices, firing all the good support staff and replacing them with
know-nothings, etc.

Flee.  EIG killed Bluehost, A Small Orange, Hostgator, Site5, and a
multitude of others.

Sincerely,

-tkc who has been burned multiple times by EIG buy-outs

Re: Using iPage for email host

[Sören Mindorf]

Hi Lucas,

I checked the FAQ from ipage.
You should use startssl for Port 587.

It is described in the Django email instructions.

EMAIL_USE_TLS is needed!

Kind regards,
Soeren

Re: Using iPage for email host

[Sören Mindorf]

Hi Lucas,

i don't know this provider, maybe there is something not correct.
Did you try to deliver an email via telnet to see what is going wrong?


https://mediatemple.net/community/products/dv/204404584/sending-or-viewing-emails-using-telnet

But remember to use port 587.

Kind regards,

Using iPage for email host

[Lucas McBride]

Does anyone have any experience using iPage for an email host with Django?

I've tried using the instructions 
 on the Django Docs 
to send emails but it doesn't seem to work:

EMAIL_HOST = 'smtp.ipage.com'
EMAIL_HOST_USER = 'info@be-a.rocks'
EMAIL_HOST_PASSWORD = ''
EMAIL_PORT = 143

Using these settings I just get an SMTPConnectError:

(-1, b'[CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE 
UNSELECT STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.')


Does anyone know what is going on? Or what I have to do differently? 

I used this method for a Gmail account and it worked fine, but with iPage 
it seems to be different. 

Thanks!

Lucas

Re: Using iPage for email host

Hey Lucas,

you tried the imap Port not the smtp port.
Dovecot is an imap service not smtp!

Try port 587 this should be the right post to deliver emails as client.

Re: do i always have to reload/return render a page to show the errors? if i press go back on browser, i see screens with the error message

I'm using python code to verify the fields. I'm doing it on a View. But 
with javascript maybe I can solve this issue where i don't need to reload 
the page. But if i do that, can i do things like check the database to see 
if it already contains some value? Or store something on request.session

Quite honestly, instead of doing all of this work, why not just
amend STATICFILES_DIRS with the location of your extra folder? Or just use
the designated 'static/app_name' location for your JS files? Seems like a
ton of trouble now and in the future to try and implement your own file
structure. A symlink from catalog -> static/fred would also have the same
effect if you are on a Linux system.

executing python script in html button

[Rizal M.]

I have custom python script for twitter sentiment analysis, let's call it 
sentiment.py
it has two inputs, topic query and number of tweets.

this is the full code

import sys
import csv
import tweepy
import matplotlib.pyplot as plt

from collections import Counter
from aylienapiclient import textapi

if sys.version_info[0] < 3:
   input = raw_input()

## Twitter credentials
consumer_key = "xxx"
consumer_secret = "xxx"
access_token = "xxx"
access_token_secret = "xxx"

## AYLIEN credentials
application_id = "xxx"
application_key = "xxx"

## set up an instance of Tweepy
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)

## set up an instance of the AYLIEN Text API
client = textapi.Client(application_id, application_key)

## search Twitter for something that interests you
query = input("topic? \n")
number = input("number of tweets? \n")

results = api.search(
   lang="en",
   q=query + " -rt",
   count=number,
   result_type="recent"
)

print("--- Gathered Tweets \n")

## open a csv file to store the Tweets and their sentiment
file_name = 'Sentiment_Analysis_of_{}_Tweets_About_{}.csv'.format(number, query)

with open(file_name, 'w', newline='') as csvfile:
   csv_writer = csv.DictWriter(
   f=csvfile,
   fieldnames=["Tweet", "Sentiment"]
   )
   csv_writer.writeheader()

   print("--- Opened a CSV file to store the results of your sentiment 
analysis... \n")

## tidy up the Tweets and send each to the AYLIEN Text API
   for c, result in enumerate(results, start=1):
   tweet = result.text
   tidy_tweet = tweet.strip().encode('ascii', 'ignore')

   if len(tweet) == 0:
   print('Empty Tweet')
   continue

   response = client.Sentiment({'text': tidy_tweet})
   csv_writer.writerow({
   'Tweet': response['text'],
   'Sentiment': response['polarity']
   })

   print("Analyzed Tweet {}".format(c))

## count the data in the Sentiment column of the CSV file
with open(file_name, 'r') as data:
   counter = Counter()
   for row in csv.DictReader(data):
   counter[row['Sentiment']] += 1

   positive = counter['positive']
   negative = counter['negative']
   neutral = counter['neutral']

## declare the variables for the pie chart, using the Counter variables for 
"sizes"
colors = ['limegreen', 'dodgerblue', 'darkorchid']
sizes = [positive, negative, neutral]
labels = 'Positif', 'Negatif', 'Netral'
explode = (0.1, 0, 0)

## use matplotlib to plot the chart
plt.pie(
x=sizes,
shadow=False,
colors=colors,
labels=labels,
startangle=90,
explode=explode,
autopct='%1.0f%%'
)
plt.axis('equal')
plt.title("Sentiment of {} Tweets about {}".format(number, query))
plt.show()


how to execute that file in html web page.
let's say in the web page, there are two input texts, topic and number, and 
when I press the submit button, it executes the python script.

I'm new to this Django so please explain it with detail,

Hello all, try to make dropdown in form

[JP]

Hello all,
any help would be appreciated, I think this is basic stuff but can find how 
to do it online

So I made the class and the form and the view
every thing works but the background color of the drop down menu in the 
form is black and txt is grey (white when mouse is over). I don t think I 
have change default option, I really dont think these are default color.

How can I put white back ground and back text??
I follow this great tutorial and am trying to change a text field in the 
form and put drop down instead

https://www.youtube.com/watch?v=v5FWAxi5QqQ=33=PL6gx4Cwl9DGBlmzzFcLgDhKTTfNLfX1IK

here is some code:

product_type = models.CharField(max_length=100, choices = 
product_categories)




{{ field.errors }}

{{ field.label_tag }}
{{ field }}
...


Thanks for the help!

ManytoMany field in Django admin not appearing

[Paul]

 

I have a Product model, an Image Model and a Category Model.

A Product can have multiple Images(Foreign Key) and a Product can be in 
multiple Categories a Category can contain multiple Products.

A Category can have multiple subcategories(key to itself).


class Category(MetaData): 
 parent = models.ForeignKey('self', blank=True, null=True, verbose_name='parent 
category', on_delete=models.CASCADE) 

class ProductMetaData): 
  categories = models.ManyToManyField(Category) 

class ProductImage(models.Model):  
  product = models.ForeignKey(Product, related_name='image', on_delete=
models.CASCADE)



In Product Django Admin: 

class ProductDocumentInline(admin.TabularInline): 
 model = ProductDocument class ProductAdmin(MetaData):
 inlines = [ProductImageInline]
 fieldsets = (
 ('Product Data', {
 'fields': ('name', 'short_description', 'description')
 }),
 ('SEO', {
 'classes': ('collapse',),
 'fields': ('meta_title', 'meta_description', 'slug', 'canonical')
 }),
 ('MetaData', {
 'classes': ('collapse',),
 'fields': (('created_at', 'created_by'), ('updated_at', 'updated_by'))
 }),
 )
 readonly_fields = ('created_at', 'updated_at', 'created_by', 'updated_by')
 list_display = ('name', 'updated_at')
 ordering = ('-updated_at',)
 search_fields = ('name',)


admin.site.register(Product, ProductAdmin)
admin.site.register(ProductImage)



Issues:

   1. 
   
   If I don't customize fieldsets (grouped, ordered) the Categories appear 
   like default in the middle of the form. If there are customized as in my 
   example they don't appear.
   2. 
   
   If they don't appear Products without Categories can be created and I 
   don't want that. I want a product to have at least one category.
   3. 
   
   Now the inline Images appear below all Product fields. 
   
I want the Categories to appear first, then normal fields for 
Product(grouped,ordered), Images inline and at the end the SEO and metadata 
fields. How can this be done ?

Re: return jwt token as json

[Jani Tiainen]

According to pyjwt docs it can be either datetime object or number (unix
epoch)

Re: return jwt token as json

   if user:
   payload = {
   'id': user.pk,
   'username': user.username,
   'staff': user.email,
   'exp': datetime.utcnow()


I think that datetime.utcnow() returns a datetime object, not a string, and
I don't think it can be serialized directly. You should try converting that
object to a string in the right format. As a test, substitute a static
string containing a date and time in whatever format you need. I'm not in
front of an interpreter so I can't test, but this seems to back up my
theory:

https://code-maven.com/serialize-datetime-object-as-json-in-python


Forgot to mention, you may also want to take a look at the built-in JSON
encoder, which handles datetime objects:
