Overriding or Changing Admin Templates in Django 1.11
My general goal is to make the data in /admin/my_app/my_model/<id>/change/ not editable or the link that goes to that page to go to another URL that's just view instead of change. I'm having a lot of trouble figuring out how to extend these templates. A lot of tutorials and docs I see talks of changing the templates in /templates/admin but I get the feeling that that's been deprecated in 1.11. -
using file stored on aws s3 storage -- media storage as input of a process in django view
I am trying to make my django app in production in aws, i used elastic beanstalk to deploy it so the ec2 instance is created and connected to an rds database mysql instance and i use a bucket in amazon s3 storage to store my media files on it. When user upload a video, it is stored in s3 as : "https://bucketname.s3.amazonaws.com/media/videos/videoname.mp4". In django developpement mode, i was using the video filename as an input to a batch script which gives a video as output. My view in developpement mode is as follow: def get(request): # get video var = Video.objects.order_by('id').last() v = '/home/myproject/media/videos/' + str(var) # call process subprocess.call("./step1.sh %s" % (str(v)), shell=True) return render(request, 'endexecut.html') In production mode in aws (Problem), i tried: v = 'https://bucketname.s3.amazonaws.com/media/videos/' + str(var) but the batch process doesn't accept the url as input to process. How can i use my video file from s3 bucket to do process with in my view as i described ? Thank you in advance. -

Break loop in one consumer from another consumer
I'm building web-app with Django and Django Channels that utilizes websockets. When user clicks the button in browser, websocket sends data to my server and consumer on the server starts to send messages to the client once per second (in loop). I want to create another button that will stop this data sending process. When user clicks on this new button, websocket sends another data to server and consumer on the server must somehow stop the loop in previous consumer. Also I will require this to stop the loop when client disconnects. I've tried to use channel session. I made second consumer to update value in channel session, but channel session values didn't get updated in first consumer. Here is simplified code. Browser: var socket = new WebSocket("ws://" + window.location.host + "/socket/"); $('#button1').on('click', function() { socket.send(JSON.stringify({action: 'start_getting_values'})) }); $('#button2').on('click', function() { socket.send(JSON.stringify({action: 'stop_getting_values'})) }); Consumer on server: @channel_session def ws_message(message): text = json.loads(message.content['text']) if text['action'] == 'start_getting_values': while True: # Getting some data here # ... message.reply_channel.send({"text": some_data}, immediately=True) time.sleep(1) if text['action'] == 'stop_getting_values': do_something_to_stop_the_loop_above() -
How do I compare a CombinedResponse object value with an int?
I'm trying to annotate a query with a percentage that repsents how "complete" the business logic is. I don't want that percentage to go over 100%. I currently have this in my query: .annotate(completion=max(100, Count('id')/F('something_tricky') ) The issue is that Count/F is a CombinedExpression, which is unorderable, so can't be used in max. It won't let me cast it to an int either: int() argument must be a string, a bytes-like object or a number, not 'CombinedExpression' Or to a String. How do I get the completion value as an int out of this query? -
Configure apache to respond with error page for incorrect hosts
django docs: You should also configure the Web server that sits in front of Django to validate the host. It should respond with a static error page or ignore requests for incorrect hosts instead of forwarding the request to Django. This way you’ll avoid spurious errors in your Django logs (or emails if you have error reporting configured that way). For example, on nginx you might setup a default server to return “444 No Response” on an unrecognized host: I am using Apache and this works: http://serverip -> 404 error http://www.example.com -> https://www.example.com -> django site http://example.com -> https://example.com -> django site Now I have a problem with https://serverip I get a not secure message by my browser because I only have a SSL Cert for example.com, www.example.com and after I accept the security warning I see the django site but I want 404 error page. How can I achieve this or do I misunderstand the django docs? -

Django: Is there a way to move from a GET request to a POST request if the requested data is not found?
I am making a weather API using Django where a user calls something like: http://127.0.0.1:8000/weather/<latitude>,<longitude> My application is supposed to query the database and return the data if found. If the data is not present or outdated, the app will create or modify an entry by accessing a 3rd party weather API to pull relevant data. Right now, I'm using the get_or_create() function within my get function in views.py to accomplish this. From what I've read, doing this is bad practice and any database modification should be done as a POST or PUT. I'm uncertain if this is something that I can do or if I am approaching this problem in the wrong direction. My app doesn't currently do everything I said it should do, but it does create entries if they don't exist. What I want is for my app to jump to a POST/PUT after determining that the entry needs to be created or updated. views.py def get(self, request, *args, **kwargs): # Process latitude and longitude coordinates from URL coordinates = kwargs.pop('location', None).split(",") latitude = coordinates[0] longitude = coordinates[1] # Retrieve the Location by latitude and longitude # If it doesn't exist, create an entry to generate a … -

Why csrftoken cookie works?
I am upgrading from Django 1.4.3 to Django 11.3. I have a web page with 2 different forms. Both forms are loaded with {%csrf_token%}. The flow is - the user logins in using form 1 ( ajax ) and then the second form is displayed. The user enters data in the second form and submits using ajax. Now, this request was failing if I did ( worked under Django 1.4.3 ) - csrfmiddlewaretoken = $form.find('input[name="csrfmiddlewaretoken"]').val(); Now, to fix this I am getting csrftoken value from cookie and sending the cookie as part of ajax and it works - csrfmiddlewaretoken = _getHelperCookie('csrftoken'); I am confused why getting the client cookie works? After login, Django calls rotate_token; what actually does this affect? -

Django input as hour and minutes, saved as minutes
In my django webapp, I'm creating a form where a user inputs the time taken to complete an activity in hours and minutes (eg. 2 hours, 33 minutes).

I worry this is fairly ugly/unreadable: models.py: class Activity(models.Model): time_taken = models.PositiveIntegerField(default=0) add_activity.html: <form id="add_session_form" method="post" action="" enctype="multipart/form-data"> {% csrf_token %} {{ add_activity_form.as_p }} <input type="submit" name="submit" value="Add Activity" /> </form> Could somebody please assist me in altering the form's input so that users individually enter the hours AND minutes, whilst only storing the time in minutes. -
Django - Exclude current post from side bar
I am playing with django but im having trouble with my templates. In my post detail im including a recent posts side bar from a templatetag but i want to exclude the current post if it is in fact one of the most recent.

How to solve this type of forms-list views in Django?

Rename a directory after extracting zip archive uploaded by user
I'm trying to rename the directory after extracting it in a temporary directory.The archive upload by user. What I mean, User will upload a .tar OR .zip file then I will make a temporary directory and extract user's file into that directory, now I want to rename it extracted directory which is inside temporary directory. Here's what I have tried: In my views.py if form.is_valid(): deployment = TarWithoutDocker() deployment.name = form.cleaned_data['name'] deployment.user = request.user deployment.archive = form.cleaned_data['archive'] deployment.save() tmpdir = tempfile.mkdtemp() saved_umask = os.umask(0o077) path = os.path.join(tmpdir) arpath = deployment.archive.path patoolib.extract_archive(arpath, outdir=path) os.rename(path + '/' + deployment.archive.name[:-4], 'archive') print(path+'/'+deployment.archive.name[:-4]) But when I print print(path+'/'+deployment.archive.name[:-4]) it should print users' file name without .zip OR .tar extension. See what it prints out: archives/frequent_sign_in_form-web_Free18-07-2017_1046736122_9aAbZpD.zip patool: Extracting /Users/abdul/Documents/IGui/media/archives/frequent_sign_in_form-web_Free18-07-2017_1046736122_9aAbZpD.zip ... patool: ... /Users/abdul/Documents/IGui/media/archives/frequent_sign_in_form-web_Free18-07-2017_1046736122_9aAbZpD.zip extracted to `/var/folders/g2/8fzl8mjj5xxfqdfvrl7v3q_40000gn/T/tmpj8gzegdq'.
