How to display multiple pie charts based on multiple lists?

2020-05-12 Thread ratnadeep ray

Hi all, 

I have a requirement where I need to display multiple pie charts based on 
multiple lists. 

Currently, I am able to display one pie chart involving 2 lists. Below is 
the views.py code for the same: 

# Create your views here.
from django.shortcuts import render

def pie_chart(request):
labels = ["A", "B", "C"]
data = ["10", "15", "2"]

   return render(request, 'pie_chart.html', {
'labels': labels,
'data': data,
})

Now what if we have another pair of lists as follows: 
labels1 = ["X", "Y", "Z"]
data1 = ["10", "15", "2"]

So can anyone say what changes should I made in the above code  to display 
2 pie charts displaying labels/data and labels1/data1 ? 

Thanks in advance.

How to over ride the get context data method in view

2020-05-12 Thread Ahmed Khairy



I am currently trying to create a like button for my posts in Django

I have reached to the part where I can add a like but I am facing 
difficulty writing the code related to the view which linking the 
PostListView if there is user who liked it or not. I am getting an error: 
page Error 404 although everything is correct


this the views: 


class PostListView(ListView):
model = Post
template_name = "score.html"
ordering = ['-date_posted']
context_object_name = 'posts'
queryset = Post.objects.filter(admin_approved=True)
paginate_by = 5

def get_context_data(self, **kwargs):
post = get_object_or_404(Post, id=self.request.POST.get('post_id'))
context = super(PostListView, self).get_context_data(**kwargs)
context['posts'][0].likes.filter(id=self.request.user.id).exists()
is_liked = False
if post.likes.filter(id=self.request.user.id).exists():
is_liked = True
context = {'post': post,
   'is_like': is_liked,
   }
return context



def like_post(request):
post = get_object_or_404(Post, id=request.POST.get('post_id'))
is_liked = False
if post.likes.filter(id=request.user.id).exists():
posts.likes.remove(request.user)
is_liked = False

else:
post.likes.add(request.user)
is_liked = True

return HttpResponseRedirect(post.get_absolute_url())


This is the model 


class Post(models.Model):
designer = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=100)
date_posted = models.DateTimeField(default=timezone.now)
likes = models.ManyToManyField(User, blank=True, related_name='likes')

def __str__(self):
return self.title

Here is the

path('like/', like_post, name='like_post'),

here is the template: 

{% extends "base.html"%} {% block content %} {% for post in posts %}
{{post.title}}

  {% csrf_token %} {% if is_like %}
  
  Unlike
  {% else %}
  Like
  {% endif %}Likes 

{% endfor %} {% endblock content %}

Adding a default Variation when creating a new Item

2020-05-12 Thread Ahmed Khairy

I have created this code for defining a default everytime I create a new 
product, 

It is working fine and whenever I create a new Item a new variable (size) 
is create 

I want to check whether this code is correct or not as I have had help from 
someone and I think we could have created an easier way for it 


class Item(models.Model):

price = models.DecimalField(decimal_places=2, max_digits=100)
category = models.CharField(choices=CATEGORY_CHOICES, max_length=2)
label = models.CharField(choices=LABEL_CHOICES, max_length=1)
slug = models.SlugField(unique=True)
timestamp = models.DateTimeField(default=timezone.now)
active = models.BooleanField(default=True)

def __str__(self):
return self.title

class VariationManager(models.Manager):
def all(self):
return super(VariationManager, self).filter(active=True)

def sizes(self):
return self.all().filter(category='size')

def colors(self):
return self.all().filter(category='color')


VAR_CATEGORIES = (
('size', 'size',),
('color', 'color',),
('package', 'package'),
)


class Variation(models.Model):
item = models.ForeignKey(Item, on_delete=models.CASCADE)
category = models.CharField(
max_length=120, choices=VAR_CATEGORIES, default='size')
title = models.CharField(max_length=120)
objects = VariationManager()
updated = models.DateTimeField(auto_now_add=False, auto_now=True)
active = models.BooleanField(default=True)

def __str__(self):
return self.title

@receiver(post_save, sender=Item)
def add_default_Variant(sender, instance, **kwargs):
small_size = Variation.objects.create(
item=instance, category='size', title='Small')
medium_size = Variation.objects.create(
item=instance, category='size', title='Medium')
large_size = Variation.objects.create(
item=instance, category='size', title='Large')

Re: gdal installed still

It looks like you are running on Windows which I’m not familiar with. But most 
likely your gdal installation is in a different Python installation than your 
django installation.

Incorrect query generated from ~Q/exclude

2020-05-12 Thread kirk

Django 2.2.12
Python 3.7.5
Postgres 10.11

I am receiving what I perceive to be an incorrect SQL query from a Django 
queryset.  I am hoping I've just done something wrong.

Here's the setup:

from django.db.models import DecimalField, DO_NOTHING, F, ForeignKey, Model, 
Q, Sum, TextField


class TableA(Model):
name = TextField()

class Meta:
db_table = "tablea"


class TableB(Model):
tablea = ForeignKey(TableA, DO_NOTHING, null=True)
value = DecimalField(max_digits=5, decimal_places=2)

class Meta:
db_table = "tableb"

Here's some sample data:

insert into tablea (id, name)
select * from (values (1, 'NAME 1'), (2, 'NAME 2'), (3, 'NAME 3')) t;

insert into tableb (id, tablea_id, value)
select * from (values
(1, 1, 0), (2, 1, 5),
(3, null, 13),
(4, 2, 0), (5, 2, 0),
(6, 3, -1), (7, 3, 1)
) t;

The goal is to group names from tablea and sum values from tableb where 
value != 0.  If I were to write it purely in SQL I'd probably do something 
like this:

select   a.name, sum(b.value)
from tablea a inner join tableb b on b.tablea_id = a.id
whereb.value != 0
group by a.name;

The answer should be:

NAME 3 0
NAME 1 5

If I write the Django queryset as one of the following:

qs = (
TableA.objects.filter(~Q(tableb__value=0))
.annotate(the_name=F("name"), the_sum=Sum("tableb__value"))
.values("the_name", "the_sum")
)

qs = (
TableA.objects.exclude(tableb__value=0)
.annotate(the_name=F("name"), the_sum=Sum("tableb__value"))
.values("the_name", "the_sum")
)

I get SQL that I really didn't expect:

SELECT   "tablea"."name" AS "the_name",
 SUM("tableb"."value") AS "the_sum"
FROM "tablea"
 LEFT OUTER JOIN "tableb" ON ("tablea"."id" = "tableb"."tablea_id")
WHERENOT (
"tablea"."id" IN (
SELECT  U1."tablea_id"
FROM"tableb" U1
WHERE   (U1."value" = 0 AND U1."tablea_id" IS NOT NULL)
)
 )
GROUP BY "tablea"."id";

which returns the wrong answer:

NAME 3 0

If I rewrite the queryset as such, I get the correct answer:

qs = (
TableA.objects.filter(Q(tableb__value__gt=0) | Q(tableb__value__lt=0))
.annotate(the_name=F("name"), the_sum=Sum("tableb__value"))
.values("the_name", "the_sum")
)

This translates to:

SELECT   "tablea"."name" AS "the_name",
 SUM("tableb"."value") AS "the_sum"
FROM "tablea"
 INNER JOIN "tableb" ON ("tablea"."id" = "tableb"."tablea_id")
WHERE"tableb"."value" > 0 OR "tableb"."value" < 0
GROUP BY "tablea"."id";

Am I doing something wrong in my ~Q/exclude querysets?  Is this working as 
intended?

Thanks!

My rule of thumb is that if an image is referenced in the database then
it goes under "media".

Re: Can I use Django for client-server communication ?

2020-05-12 Thread Sharanagouda Biradar

*Let me re-phrase my question.*

I have a basic (server1) Django development web server and another server 
(ex:server2) - (actually multiple windows 10 machines not just 1 machine.) 
which has a python/batch script that launches a python application. Assume 
that the server1 has necessary authentication in place to run the script on 
server2. All I want to do is, click a button on the django website which 
would run the python script sitting on server2. Now can this be achieved 
using Django REST APIs? or how else can i achieve this? help is highly 
appreciated.

PS: reply from Mohammed Khalid seems its possible using Django REST 
Framework, just need one more confirmation as i have re-phrased my question.

Can I use a JS Framework to display small JS tasks in a Django project?

2020-05-12 Thread Alexander Rogowski



I have an idea to simplify the online experiments from our university. But 
I'm not so familiar with the newest FE frameworks eg. react, angular, vue. 
Any answer on this post is appreciated :)

The idea is, to put our experiments in two folders, "tasks" and 
"treatments". A task could be something trivial like put some sliders on 
the right position or write with a chatbot (this should be coded in js, I 
guess?) and in treatments could be something like collecting badges or the 
setting for the chatbot (e.g. human-like/machine-like).

My question is: Can I use a JS Framework to load the content from the two 
directories and show them as options on a main page? After selecting the 
task and the treatments, it would generate a page with the selected items, 
e.g. the chatbot with the human-like setting.

I Would like to do this with Django (because I already worked with it) so 
we can create unique links to send them to the probands. Is Django with a 
JS Framework the right decision? How would you approach the problem?

How to Run script on remote server from Django Webserver - Help needed

2020-05-12 Thread Sharanagouda Biradar

Hello All,

I have started learning Django last one week and able to fairly understand 
basic poll application in tutorial, Now I need any of your help in meeting 
my requirements:

*Requirement below :*

I have a basic (server1) Django development web server and another server 
(server2) which has a python script that will launch local application. 
Assume that the server1 has necessary authentication in place to run the 
script on server2. All I want to do is, click a button on the django 
website which would run the python script sitting on server2. Apart from 
above I need to get status of tests running as part of server2 application, 
along with csv files from Server2 back to server1 (web server).

Can I achieve the above requirement using Django REST APIs? or Django 
Remote submission ? I am really clueless here, any pointers are highly 
appreciated.

"The read operation timed out" means that your connection to wherever 
you're downloading the packages from was too slow and the connection was 
closed.


Not too much to do about that other than trying again or download it 
from somewhere where you have a faster connection.

Re: TestCase failing when using transaction.atomic() inside test

2020-05-12 Thread Uri Kogan

Continuing my investigation I got the a following which does not work but 
should:
from django.contrib.auth.models import User
from django.test import TransactionTestCase
from django.db import transaction

class FooTest(TransactionTestCase):
def test_bar(self):
with transaction.atomic():
with transaction.atomic():
u = User.objects.create_user(username="abc", 
password="pass")
print("created user: {}".format(u.username))

The crash of "SAVEPOINT does not exist" occurs when exiting inner `
*transaction.atomic*' block.

 When testing django apps, my unit test usually accesses the django app

 Django test client simulates http access, so my Django tests always run

 Even though there must be many django app code that has 
 `transaction.atomic` inside it, I never need to add `transaction.atomic`

 If I need to simulate initial state by having some data inserted to

Re: TestCase failing when using transaction.atomic() inside test

2020-05-12 Thread Uri Kogan

The documentation states that "you cannot test that a block of code is 
executing within a transaction" while I am looking to "test a block of code 
that has a transaction".
In any case, the issue here is that "transaction.atomic" does not work when 
nested while it should clearly work.

Re: TestCase failing when using transaction.atomic() inside test

2020-05-12 Thread Aldian Fazrihady

Probably you need to use TransactionTestCase, which is the parent of
TestCase instead:
https://docs.djangoproject.com/en/3.0/topics/testing/tools/#transactiontestcase
That page also mentions a specific problem when using transaction on
TestCase:
```
A consequence of this, however, is that some database behaviors cannot be
tested within a Django TestCase class. For instance, you cannot test that a
block of code is executing within a transaction, as is required when using
select_for_update()
.
In those cases, you should use TransactionTestCase.

Re: TestCase failing when using transaction.atomic() inside test

2020-05-12 Thread Uri Kogan

That not that simple in my case because. I'll show what I mean:

from django.contrib.auth.models import User
from django.test import TestCase
from rolepermissions.roles import assign_role

class FooTest(TestCase):
def test_bar(self):
u = User.objects.create_user(username="abc", password="pass")
assign_role(u, "role_admin")
retrieve_and_analyze_view_using_u_credentials()

I am testing that my permission routines work by creating a user, assigning 
permissions to the user, retrieving the view and analyzing it. That "
assign_role" call of django-role-permissions uses "transaction.atomic". 
Which, of course, I would not want to change, as this is an external 
library.

So I can't really remove usages of "transaction.atomic"

 Hello,

 I am using TestCase and trying to create an object during test.
 There is a log activated on MySQL server, so I see all the queries 
 being executed there.

 This "transaction.atomic" sets a SAVEPOINT in the database thinking 
 that the transaction is already started. The problem is that there is no 
 "TRANSACTION START". So, when exiting "with transaction.atomic()" block 
 the 
 whole thing crashes with "SAVEPOINT xxx DOES NOT EXIST"

 The following states that TestCase "tests within two nested atomic() 
 blocks", so it should execute "TRANSACTION START"

 https://docs.djangoproject.com/en/3.0/topics/testing/tools/#django.test.TestCase

 
 from django.contrib.auth.models import User
 from django.test import TestCase


 class FooTest(TestCase):
 def test_bar(self):
 with transaction.atomic():
 user = User.objects.create_user(username="abc", 
 password="pass")

Re: TestCase failing when using transaction.atomic() inside test

2020-05-12 Thread Aldian Fazrihady

When testing django apps, my unit test usually accesses the django app via
django test client:
https://docs.djangoproject.com/en/3.0/topics/testing/tools/#the-test-client.
Django test client simulates http access, so my Django tests always run my
Django code starting from Django views.
Even though there must be many django app code that has
`transaction.atomic` inside it, I never need to add `transaction.atomic` in
my unit test code.
If I need to simulate initial state by having some data inserted to
database, I did that either using factoryboy or django ORM framework, but I
see no point to add `transaction.atomic` to that data initialization code.

I think, for that you'll have to show your "mail_item" model too.
