Transcoding with AWS- part five
This is the last blog post in this series - the only thing that has to be done is telling the user that file he or she uploads is processed. It will be done by writing custom message application. Tabel of Contents: How message application should work Implementation in django Other blog posts in this series How message application should work From previous post I know that the last point of my application flow is to inform user that file is transcoded and ready to download. To do such thing I have to display message on every webpage that current user is. This message should have information about which file was processed. First I wanted to do this with existing django messaging framework but as it turns out is works only with request. As I decided to show message for different users as long as they dismiss this information I had to write my own small application. Implementation in django In my newly created application I created following model: from django.db import models from django.contrib.auth.models import User class Message(models.Model): text = models.CharField(max_length=250) read = models.BooleanField(default=False) def __str__(self): return self.text I decided to display my message only when it wasn't read. … -

How I Deploy Django Day-to-Day
There are a lot of ways to deploy Django so I think it is one of those topics people are really curious about how other people do it. Generally, in all deploys you need to get the latest code, run migrations, collect your static files and restart web server processes. How yo do those steps, that is the interesting part. In todays video I go over How I deploy Django day to day, followed by some other ways I have done it. This is definitely a topic you can make as easy or complicated as you want. Here is the link again: https://www.youtube.com/watch?v=43lIXCPMw_8?vq=hd720 -
Why does Django not email me the 500 internal server error?
You’ve set your EMAIL_* settings correctly, and when you try to send emails with django.core.mail.sendmail() it works. However, Django still does not send you internal server errors. Why? The sender’s email address matters SERVER_EMAIL is the email address from which emails with error messages appear to come from. It is set in the “From:” field of the email. The default is “root@localhost”, and while “root” is OK, “localhost” is not, and some mail servers may refuse the email. The domain name where your Django application runs is usually OK, but if this doesn’t work you can use any other valid domain. The domain of your email address should work properly. → Set SERVER_EMAIL → When testing with django.core.mail.sendmail(), use the same sender email address as the one you’ve specified in SERVER_EMAIL. The recipient’s email address matters Because of spam, mail servers are often very picky about which emails they will accept. It’s possible that even if your smarthost accepts the email, the next mail server may refuse it. For example, I made some experiments using EMAIL_HOST = 'mail.runbox.com' and this command: send_mail('Hello', 'hello, world', 'noreply@example.com', ['anthony@itia.ntua.gr']) In that case, Runbox accepted the email and subsequently attempted to deliver it to … -
New Django Admin with DRF and EmberJS... What are the news?
A couple months ago, I published a post titled "Yes I want a new admin". Now that more than a few weeks have gone by, I want to bring you up to speed on the progress. In the original post, it was mentioned that, in order to achieve this goal, several libraries would be needed and that some of these libraries were already published. Among them were DRF-auto-endpoint and djember-model. During Django Under The Hood's sprints, we got together with several people interested by the concepts of those two libraries, merged them in a signle library (DRF-schema-adapter) and added some functionalities. Other than being a merge of the two "old" libraries DRF-schema-adapter also brings the concept of adapters which make it possible to use the same library for different frontends. DRF-schema-adapter pursues 3 main goals: Making it as easy, fast and straight-forward to define an API endpoint as it would be to generate a ModelAdmin class. Letting developpers be DRYer by generating frontend code (models, resources, stores, ...) based on your DRF endpoints. Providing enough information to the client to be entirely dynamic. Although there are still some improvements planned for the library, all 3 of these goals have been … -
Using Python weasyprint generate HTML to PDF in django
In most of the web development projects you might want to automate file generation, like for example placeorder confirmation receipts, payment receipts, that can be based on a template you are using.

You can also pass the CSS File, This can be done using: from django.conf import settings … -
Transcoding with AWS- part four
As I have my transcoder up and running now it's time to let user know that their uploaded files were transcoded. To this occasion I will use AWS SNS service which allows me to send notification about completion of transcode job. Table of Contents: Setting up AWS SNS to work with AWS Transcoder Receiving notifications from SNS service in Django Other blog posts in this series Setting up AWS SNS to work with AWS Transcoder After logging to AWS console and selecting SNS I have to create a topic: Topic is endpoint for other application in AWS to send their notifications.

New year, new Python: Python 3.6
Python 3.6 was released in the tail end of 2016. Read on for a few highlights from this release. New module: secrets Python 3.6 introduces a new module in the standard library called secrets. While the random module has long existed to provide us with pseudo-random numbers suitable for applications like modeling and simulation, these were not "cryptographically random" and not suitable for use in cryptography. secrets fills this gap, providing a cryptographically strong method to, for instance, create a new, random password or a secure token. -
Which components should I use in production?
This is the last in a series of posts about whether you should choose Ubuntu or Windows, Gunicorn or uWSGI, MySQL or PostgreSQL, and Apache or nginx. I bring it altogether. The image illustrates the components I propose for a start. […]The post Which components should I use in production? appeared first on Django deployment.
