Tumbleweed badge
by Hansel Dunlop Oct. 30, 2017

Oct. 30, 2017

Hi all, So I just got a notification from Stackoverflow that this question - https://stackoverflow.com/questions/46804936/custom-django-field-type-with-… - was just awarded the tumbleweed badge (no, votes, no answers, and no views)... So throwing this open to the wider community here. I do suspect there is no way of doing this in Django. But I wish there was. Because I'm trying to create a custom translation infrastructure and it would help if I could just return the actual text in the query rather than the whole blob of json. I mean maybe I could on the fly modify the db_column value. But would that be thread safe? Doubt it. -- Hansel

Startup Row Event at Bloomberg London Office 27 November
by Steve Holden Oct. 26, 2017

Oct. 26, 2017

Hi all, Don Sheu, who among other things runs the Startup Row event for PyCon US, informs me about an event he is holding at Bloomberg's UK offices (I presume in Finsbury Square, London) on 27 November. He says: Hope you can join us in London, November 27th. Bloomberg is kindly hosting > us. If you have any startups to nominate, welcome your input. Please to > share with your friends who may have an interest in startups. If you're > making PyCon UK, hope you'll encourage folks to turn > > out. I am indeed at PyCon UK, and will be putting the word out there too. If anyone is involved with a startup that might like to enter and would like an introduction to Don to find out more, please reply confidentially to me at steve(a)holdenweb.com rather than replying to this message (which will go out to the whole list). The only link I have for the event is the ticketing link https://www.eventbrite.com/e/a-psf-pycon-startup-row-pitch-event-at-bloombe…, but that page does link to further information about Startup Row, kind regards Steve Holden

Hi there, I want to invite you to join us at a sprint to improve the events sections of www.python.org: https://www.meetup.com/Python-Sprints/events/244388482/ The idea is to make more efficient the process of adding events to the site, both for meetup and conference organizers, and also for the events moderators. The sprint will be hosted by Bloomberg (thanks!), and will happen on the 1st of November at 6:30pm. We are organizing sprints almost every week. If you're interested in contributing to Python projects feel free to join the group, even if you can't attend to this sprint. Cheers! Marc

Burning desire to watch cataract surgery?
by Hansel Dunlop Oct. 16, 2017

Oct. 16, 2017

Probably not, in fact I probably don't want to watch another one in my life if I can help it. BUT: For those who know me, and for those that don't. The company I'm working for (It's called Touch Surgery, and I look after the platform team) is growing quickly at the moment. There are a broad range of technical roles. I'm particularly keen to find some Python devs who have worked on large Django projects but anyone senior looking for something exciting would be of great interest. We're doing all kinds of interesting things with surgical simulations and surgical video. Engineering team is around 27 people at the moment. We're trying to create an engineering culture that we're all proud of. It's good people, doing quality work, in a diverse environment. I'm really proud of what we're doing and how we're doing it. I wrote a blog post about some of the process refactoring I've been doing. <https://medium.com/tsengineering/refactoring-touch-surgerys-infrastructure-…> All our job listings are here. There are actually a bunch of not so technical roles as well. So please do click the link and have a look <https://www.touchsurgery.com/jobs.html>. Hopefully catch up with everyone at Pycon UK. And do click those links! Much love! *Hansel Dunlop* Head of Platform <http://bit.ly/1N31p0A> Download the app <https://app.adjust.com/5nvgai>

Pyweek 24 is next week
by Daniel Pope Oct. 9, 2017

Oct. 9, 2017

Next week will be Pyweek 24! Pyweek is a week-long games programming contest, which has been running since 2005 [1]. Entrants create a game in Python in exactly one week, on a theme chosen by vote, and which will be rated by other entrants on criteria of fun, production, and innovation. Theme voting has just begun, and the potential themes are: - I never saw that coming - It's too dangerous - Los Angeles has been saved - Storm's dying down - They're behind everything This time, for the first time, it will be possible to write games in Godot Engine [2] and in Unreal Engine 4 [3], which I'm really excited by! If you have an evening or two (or more) free next week, why not sign up and create something fun? You can enter as a team or as an individual. Sign up at https://pyweek.org/. [1] I have recently written a brief history of Pyweek: http://mauveweb.co.uk/posts/2017/08/fun-and-games.html [2] https://github.com/touilleMan/godot-python [3] https://github.com/20tab/UnrealEnginePython

Websockets issue with django
by Samuel Muiruri Oct. 7, 2017

Oct. 7, 2017

I have a websockets that's supposed to return data from a background process running in celery, full details Have a django project with django-channels (using redis) allows users to start background process and should get back a live feed of this on the page. Here's a recording of this: https://youtu.be/eKUw5QyqRcs Websockets disconnects with a 404. Here's the websocket's code: $('.test-parse').unbind().click(function() { ... $.ajax({ url: "/start-render-part", type: "POST", dataType: 'json', beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && sameOrigin(settings.url)) { // Send the token to same-origin, relative URLs only. // Send the token only if the method warrants CSRF protection // Using the CSRFToken value acquired earlier xhr.setRequestHeader("X-CSRFToken", csrftoken); } }, data: JSON.stringify(data), success: function(response){ if (response['status'] == 'ok') { if (response['unique-id']) { unique_processing_id = response['unique-id']; } if (response['task_id']) { task_id = response['task_id']; } var add_to_group_msg = JSON.stringify({ 'unique_processing_id': unique_processing_id, 'task_id': task_id, 'command': 'add_to_group', }); var socket = new WebSocket("ws://{HOST}/render-part/".replace('{HOST}', window.location.host)); socket.onopen = function() { console.log('opened'); var add_to_group_msg = JSON.stringify({ 'unique_processing_id': unique_processing_id, 'task_id': task_id, 'command': 'add_to_group', }); socket.send(add_to_group_msg); var get_status_msg = JSON.stringify({ 'task_id': task_id, 'unique_processing_id': unique_processing_id, 'command': 'check_status', }); socket.send(get_status_msg); }; socket.onmessage = function(event) { console.log("onmessage. Data: " + event.data); var data = JSON.parse(event.data); if (data.state == 'PROGRESS') { console.log(data.status); update_progress(data.current); } else if (data.state == 'FINISHED') { var remove_from_group_msg = JSON.stringify({ 'unique_processing_id': unique_processing_id, 'command': 'remove_from_group', }); socket.send(remove_from_group_msg); unique_processing_id = ''; task_id = ''; } }; socket.onclose = function(event) { if (event.wasClean) { alert('Connection closed'); } else { console.log('Connection terminated'); } console.log('Code: ' + event.code + ' reason: ' + event.reason); console.log(event); }; socket.onerror = function(error) { console.log("Error " + error.message); }; // Call onopen directly if socket is already open if (socket.readyState == WebSocket.OPEN) { socket.onopen(); } //End Sockets Code } //End for if rensponse['status'] == 'ok' }, error: function(xhr){ }, }); /* End Ajax Call */ }); possibly note worthy on local version the websockets get's to onopen which I confirm thanks to the console output. -- Best Regards, Samuel Muiruri.
