Hi Prateek,

Did you check disk info of server instance? What's disk consumption?

Re: Django jobs

[Ryan Gedwill]

Yeah, it’s hard to just learn the pythonic way of doing things. It’s a mix of 
functional and OOP practice with a bunch of built in stuff that you wouldn’t 
know unless you came across it. This is kind of why python can come across as a 
cult sometimes ;)

One book that I recommend for learning some pythonic ways of doing things is 
“Data science from Scratch” by Joel Grutch Of course it’s focused on an intro 
to basic data science, but anyone capable of programming and isn’t afraid of 
pretty basic math can follow along, and the way he codes his examples are very 
pythonic so you’ll pick up a lot of cool tricks. I’d also just suggest googling 
examples of pythonic code and you’ll get some good examples.

What I said in my earlier response may have came across as the opposite of what 
I meant though, I meant don’t let the pythonic way of doing things get in the 
way of doing things correctly in a way that is easier to maintain. It’s easy to 
write sloppy code with python due to its scripting nature, but it’s important 
to remember good OOP design principles and proper project architectures.

How to fix (2027, 'Malformed packet') exception?

[prateek gupta]

Hi All,

I am facing a strange issue in my pre-prod server (in dev and uat it's 
working fine).
Whenever I login in django admin and click on any table, it shows me 
following error- (2027, 'Malformed packet')

[image: db_error.JPG]

Is there any db setting I am missing here or its is related to server 
settings?
Has anyone faced this issue?

Thanks,
Prateek

Not sure about a single resource for Python. For Django however, there 
is Two Scoops of Django which claims to (and I believe) aggregate best 
practices for the web framework.


There are lots Python gurus who do presentations at PyCons around the 
world. Plenty of blogs and tutorials as well. Raymond Hettinger comes to

Google python best practices and there are heaps to choose from. You 
should pick up a sense of it by scanning a few of those pages.

Django is extremely scalable, which of course requires speed. 
It’s probably the most popular web framework among startups of any

Django certainly may require some extra optimization compared to
something like ASP.NET , just like scaling any

Instagram and Venmo are written in django, which is proof that it

There are certainly problems with scaling python and Django, a
perfect language/framework doesn’t exist, but there are benefits
to both python and Django that can be worth the tradeoff.

In addition to the fact that both Django and python are so

Re: Why does my Django project open the same home page irrespective or which url I type?

Also,
It would be better if you rearrange your patterns.

urlpatterns=[
path('login/', LoginView.as_view(template_name='accounts/login.html'), 
name='login'),
re_path(r'^$',views.home, name='home'),
]

Since your path *r'^$' *matches all request, it is better to keep this at

Re: Sending PDF from javascript to django

[Joel Mathew]

Thank you. I decided to go with reportlab since it seems to be really
powerful and doesnt require a headless browser. The options it has seem
similiar (at least superficially) to the way I'm coding js in pdfjs. Thank
you for your input. This was a XY problem after all. I should never have
thought about generating PDF on client and then uploading to server to
email the enduser.

Sincerely yours,

Joel G Mathew

Re: Django jobs

[Ryan Gedwill]

I live in the SF Bay Area and there are no shortage of jobs in Django. It is 
true there are also plenty of jobs in Node, but you can’t compare a framework 
to a backend language. I see far more python jobs than node jobs.

2 things to keep in mind though (for reference I’m a python/Django dev but have 
experience in node and c# as well):

1. Just because something is very popular doesn’t mean it’s the easiest to get 
a job in. There may be more python/JS jobs out there, but there are also way 
more people applying to them. There are plenty of .NET jobs out there, and far 
less entry level developers who are looking for them. Nearly every single entry 
level developer is looking for those python/JS jobs
2. Often times the language and framework you’re experienced in doesn’t matter. 
I recently had an interview for a Go position, and I was allowed to pick which 
language I wanted to do the interview in. Most web development jobs are looking 
for your understanding of general software and web development principles. If 
you understand html/css/js, sql databases in regards to MVC architecture, MVC 
architecture itself, and REST API’s and requests, it probably won’t matter what 
language as long as you can prove it. Knowing the language and framework of the 
company you’re applying to is kind of just brownie points and improves your 
chances. If I’m amazing at django and web development but don’t know the 
language being used, I’ll generally be chosen over someone who’s shaky on web 
development who uses the same language as the company

Re: Channels + django-tenants

[Andrew Godwin]

Hm, that's not sufficiently better than just supplying a new middleware to
be honest. The sort of hooks I prefer are where you can subclass and
improve what we ship with and give the user a new, non-fragile one, whereas
that just sounds like it's injecting a function in.

Honestly, given Channels is currently only one maintainer, any increase in
surface area is unlikely unless there's a very good reason. Channels' auth
stuff is just standard Django code + settings for the most part, so there's
already bits you can reuse to do most of the work.

There are chances you've already thought to this option, but what
about storing the sensitive data encrypted with a key based on a
passphrase the user must provide when logging, in addition to the
usual credentials ? This passphrase would not be stored anywhere,
so even if the DB is compromised, the sensitive data would not be
usable.

Hi Eric,


I am sure I have not explained myself properly.

The app does the following.

It presents a user the ability to sign up to a cloud platform for
a sandbox / playground account.
The number of cloud services that are available will change over time.

Each cloud platform has a set of credentials (username, password,
domain etc...) These credentials will have elevated permissions
within their own environments and so should be kept as safe as
possible.

Currently I use secrets and .env files to provide these credentials.
This requires physical access to the platform to add new secrets
etc...

I want to enable editing (e.g. CRUD on the platform credentials)
without having to redeploy the application or update the secrets.
The idea was to enable an admin interface to the DB so that each
cloud platform admin could add more or delete their platform from
the solution.
This requires a place to store secrets that can be updated deleted
and created.
I was hoping that there might be a standard way to store these
that is secure other than adding secrets or updating the .env file.

Thanks for trying to understand my vague question.

Lance

I'm not sure to understand the need for adding cloud details to
the app for the admins.


The suggestion I made assumed that sensitive information is
managed as K8S secrets. As long as the admins have GCloud (for
instance) credentials set (which are stored and managed at GCloud
level), they can administrate the secrets resources by "applying"
the corresponding YAML descriptors remotely from their
workstation. The sensitive values are thus stored nowhere inside
the application itself, but passed to the containers at runtime
as environment variables.


Maybe I've misunderstood your need and sorry in this case if my
answer is off topic.

Hi Eric,


Thanks for the response.


This idea has an end goal of being deployed in a resilient way so
most probably docker with some form of orchestration, Docker
swarm or Kubernetes.


The credentials are mainly stored in a .env file at the moment
and could be added to the secrets but I need for people who are
admins for a particular cloud to add their cloud details to the
app and then store their credentials securely.


Unfortunately this will need a dynamic storage mechanism which i
don't know how to do yet

Hi,


It can depend on which deployment option you plan to use for the
application.


For instance, a Docker deployment orchestrated by Kubernetes
gives the option of using secrets for sensitive information,
which a hoster such as GCP manages conveniently. In this kind of
deployment, configuration (and secrets) are passed to the app as
environment variables, on which Kubernetes configuration maps
and secrets are mapped to. Thanks to this, values

Thanks Eric,


I did not explain myself properly so the mistake was mine.


Thanks for the help.

Hi Lance,


Well, I was off topic. Sorry for this :/ I understand your need better 
now.



There are chances you've already thought to this option, but what 
about storing the sensitive data encrypted with a key based on a 
passphrase the user must provide when logging, in addition to the 
usual credentials ? This passphrase would not be stored anywhere, so 
even if the DB is compromised, the sensitive data would not be usable.

Hi Eric,


I am sure I have not explained myself properly.

The app does the following.

It presents a user the ability to sign up to a cloud platform for a 
sandbox / playground account.

The number of cloud services that are available will change over time.

Each cloud platform has a set of credentials (username, password, 
domain etc...) These credentials will have elevated permissions within 
their own environments and so should be kept as safe as possible.


Currently I use secrets and .env files to provide these credentials.
This requires physical access to the platform to add new secrets etc...

I want to enable editing (e.g. CRUD on the platform credentials) 
without having to redeploy the application or update the secrets.
The idea was to enable an admin interface to the DB so that each cloud 
platform admin could add more or delete their platform from the solution.
This requires a place to store secrets that can be updated deleted and 
created.
I was hoping that there might be a standard way to store these that is 
secure other than adding secrets or updating the .env file.


Thanks for trying to understand my vague question.

Lance

I'm not sure to understand the need for adding cloud details to the 
app for the admins.



The suggestion I made assumed that sensitive information is managed 
as K8S secrets. As long as the admins have GCloud (for instance) 
credentials set (which are stored and managed at GCloud level), they 
can administrate the secrets resources by "applying" the 
corresponding YAML descriptors remotely from their workstation. The 
sensitive values are thus stored nowhere inside the application 
itself, but passed to the containers at runtime as environment variables.



Maybe I've misunderstood your need and sorry in this case if my 
answer is off topic.



Best

Hi Eric,


Thanks for the response.


This idea has an end goal of being deployed in a resilient way so 
most probably docker with some form of orchestration, Docker swarm or 
Kubernetes.



The credentials are mainly stored in a .env file at the moment and 
could be added to the secrets but I need for people who are admins 
for a particular cloud to add their cloud details to the app and then 
store their credentials securely.



Unfortunately this will need a dynamic storage mechanism which i 
don't know how to do yet

Hi,


It can depend on which deployment option you plan to use for the 
application.



For instance, a Docker deployment orchestrated by Kubernetes gives 
the option of using secrets for sensitive information, which a 
hoster such as GCP manages conveniently. In this kind of deployment, 
configuration (and secrets) are passed to the app as environment 
variables, on which Kubernetes configuration maps and secrets are 
mapped to. Thanks to this, values are stored nowhere in the app 
code, companion files or database.

Thanks I will take a look at that

Another thought

Django admin has a built-in mechanism for password management. It 
includes forms with password widgets.Perhaps you could hack your own 
encryption of the cloud credentials based on the Django approach to 
passwords.


It is possible to add forms to the Admin and include your own logic. I 
have done that - without the extra credentials part - to create 
additional data based on converting a @domain added to a username into 
a company name and company profile.

Hi,

I have a project I am working on https://github.com/lhaig/usery/
 and
part of the roadmap of the project is to add more cloud types to
the list.

I wanted to allow admins for these services to login and create
records
for their different clouds in the DB and then use these when people
request access to these services.

I need to find a secure way to store these credentials so that
even if
the DB is compromised that the credentials are safe.

Does anyone have suggestions on how I can accomplish this?

I would really appreciate some advice.

RE: Sending PDF from javascript to django

[Matthew Pava]

There is django-hardcopy.

However, I’m in process of changing my PDF generation algorithm.  I originally 
used PhantomJS with gs-print and gs-view for Windows.  Unfortunately, PhantomJS 
has been discontinued, and it wasn’t taking advantage of rendering changes to 
HTML (especially for printing or PDF generation) that had developed over the 
years, especially with Google Chrome’s Blink engine, which used to formerly be 
Webkit, the same engine that PhantomJS was using.  My current goal is to 
utilize headless Chrome with Puppeteer, which is a NodeJS package.  Since 
PhantomJS was a NodeJS package, too, it shouldn’t be to involved to get a 
script working for Puppeteer.  And then I am guaranteed to always have the 
latest version of Chrome.

Re: Is Django REST framework a part of Django?

[Yarving Liu]

You can treat DRF as a Django package, though it's not a part of django.

DRF is the best RESTFul framework I've ever seen, and with great
integration with Django.

How to solve django.db.utils.OperationalError: (2013, 'Lost connection to MySQL server during query')?

Hi All,

I am using Django 2.0.6, Python 3.6. For connecting with Mysql 5.7 I am 
using mysqlclient 1.3.12.
Using above environment I have created an admin panel for CRUD operations.
When I select a tabel for viewing it's content following error shows-

django.db.utils.OperationalError: (2013, 'Lost connection to MySQL server 
during query')

The above error comes only for one table, rest all are working fine.

I tried to set the max_allowed_packet=67108864 in mysql configuration file 
and in settings.py I have set the CONN_MAX_AGE=6000 but it is not working.

Have anyone faced the same issue?
Let me know if anyone knows how to solve this.

Thanks,
Prateek

Sending PDF from javascript to django

[Joel Mathew]

I use jspdf to generate pdf for downloading by end users. I wish to
add a function to let them send an email to themselves through the
server.
Reading a little bit, I've seen a method to send the pdf to the server
as a base encoded string, and then have the server decode it, before
emailing the object. It seems to be bad practise and a convoluted way,
to me.

Anyway, the javascript is doing this:

var pdf = doc.output();
cliniclabel = $("#TopPatientBar").data("cliniclabel")
patient_id = $('body').find("#PatientIP").html();
$.ajax({
method: "POST",
url: 
`/clinic/${cliniclabel}/prescription/sendemail/patient/${patient_id}`,
data: {data: pdf},
}).done(function(data){
console.log(data);
});

And as a preliminary step, I'm trying to read the POST data:

def SendPrescriptionbyMail(request, cliniclabel, patient_id):
patient_id = int(patient_id)
if request.method == 'POST':
print("POST data", request.POST)
cus = customer.objects.get(cstid = patient_id)
recipient=cus.email

But I got this:
[14/Nov/2018 14:39:27] "GET
/appointments/static/appointments/js/popper.min.js.map HTTP/1.1" 404
1749
[14/Nov/2018 14:39:30] "GET /clinic/medicines HTTP/1.1" 200 8389
2018-11-14 14:39:36,360 django.security.RequestDataTooBig ERROR
Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE.
2018-11-14 14:39:36,441 django.request WARNING  Bad Request:
/clinic/madhav/prescription/sendemail/patient/18
[14/Nov/2018 14:39:36] "POST
/clinic/madhav/prescription/sendemail/patient/18 HTTP/1.1" 400 17930

But rather than create an XY problem, can anyone tell me whether I'm
approaching this in the right way? Isnt base encoding a pdf object
from javascript for sending to django the wrong way to do this?

What would be the right way? Just point me along what I need to be looking at.

Sincerely yours,

Joel G Mathew
