How to integrate Django authentication with Jinja2 templates properly?
I am trying to use authentication and authorisation system provided by Django and as I can see the default built-in views for login/logout expect Django templates, hence I cannot use my Jinja2 base.html file to extend them as I have already integrated Jinja2 engine. I was able to solve this problem by replicating 'base.html' and changing syntax to Django template, but this approach forces me to rely on two same files in different templating languages. However, now I have other issue, I cannot access the user object in Jinja2 template context, even though I can do that in Django template. By saying 'I cannot access': File "/home/dir/workspace/project/venv/local/lib/python2.7/site-packages/jinja2/environment.py", line 430, in getattr return getattr(obj, attribute) UndefinedError: 'user' is undefined My Jinja2 template: {% if user.is_authenticated %} <li>User: {{ user.get_username }}</li> <li><a href="{% url 'logout'%}?next={{request.path}}">Logout</a></li> {% else %} <li><a href="{% url 'login'%}?next={{request.path}}">Login</a></li> {% endif %} My question is, how can I go around this problem? Should I just switch back Django templates, because this becomes more and more messy. -
Django ORM get jobs with top 3 scores for each model_used
Models.py: class ScoringModel(models.Model): title = models.CharField(max_length=64) class PredictedScore(models.Model): job = models.ForeignKey('Job') candidate = models.ForeignKey('Candidate') model_used = models.ForeignKey('ScoringModel') score = models.FloatField() created_at = models.DateField(auto_now_add=True) modified_at = models.DateTimeField(auto_now=True) serializers.py: class MatchingJobsSerializer(serializers.ModelSerializer): job_title = serializers.CharField(source='job.title', read_only=True) class Meta: model = PredictedScore fields = ('job', 'job_title', 'score', 'model_used', 'candidate') I want to fetch the jobs with top 3 scores for a given candidate for each model used. So, it should return the top 3 matching jobs with each ML model for the given candidate. I read about annotations in django ORM but couldn't get much. I want to use DRF serializers for this operations. This is a read only operation. I am using Postgres as database. What should be the Django ORM query to perform this operation? -
Django static files : use only /static/ directory
I have a Django live version in production and I develop in local with Django manager.py. I'm not able to find the correct configuration settings for my static files. All my static files are on a /static/ on the root of the project, because all the sub-apps use the same stylesheets and so on. STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'staticfiles'), ) STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' On my live version : it works because I've got an NGINX rule that allow access to /static/ directly. But when I want to work on local, the static files are 404, with Debug True and False. I don't see the interest for my needings of the staticfiles directory (but I can have a wrong mind here). Is it possible to have all the static files in subdirectories in /static/ (css, img, js, etc.) and to set a workable settings on both local and live production without switching something in settings.py for deployment ? Thanks for your help :) -

django allauth signup callback?
I am working on a Django app where after a user registers/signs up, I create a an instance of 'x' on their homepage - like a new file or something. How can I achieve this? For example, I have a function create_instance() which I need to be executed like this: def after_signup_callback(): create_instance(); Should I inherit from the SignupView defined in allauth and add a method of my own? or Should I wait for the user to login and when the user arrives at the homepage (where the created instance is shown), check if its the user's first login, and then call the create_instance() method? -

Can't get POST data from Django (sending it from React)
I'm spending hours to solve this problem. The problem is I can't send POST's body data. I'm getting 500 error from the server. Here is my HTTP request on React Native (I don't think I have a problem here). There might be problem on http body? export const createCloth = (token, hType, clothObject) => async dispatch => { let headers = { 'Authorization': `JWT ${token}`}; if(hType==1) { headers = { 'Authorization': `JWT ${token}`}; } else if (hType==2) { headers = { 'Authorization': `Bearer ${token}`}; } let {image, text, clothType, ... , onlyMe} = clothObject; console.log(text); <- printing ok console.log(bigType); <- printing ok let response = await axios.post(`${ROOT_URL}/clothes/create/`, { text, clothType, ..., onlyMe }, {headers}); console.log(response.data); Here is my part of Backend API. class ClothCreateAPIView(APIView): def post(self, request, format=None): # Create Cloth # self.request.POST.get('user_id') print('--------REQUEST-------') print(request) logged_in_user = self.request.user content = self.request.POST.get('text') cloth_type = self.request.POST.get('clothType') only_me = self.request.POST.get('onlyMe') ... print('----------PRINTING CLOTH CONTENT') print(logged_in_user) <- printing my username (GOOD) print(cloth_type) <- printing None always print(content) <- printing None always At the last two line, why are they always printing None? I'm checking these syntax back and forth more than twenty times. This is so frustrating I tried with self.request.POST.get(~) request.POST.get(~) ?? -
OperationalErrors - no such column django - ForeignKey

Why are my tasks not found although they are in the database?
I'm using the library django-background-tasks: https://github.com/arteria/django-background-tasks I'm doing the example in the documentation here: http://django-background-tasks.readthedocs.io/en/latest/ I ran the the task in the shell: from forker.tasks import notify_user notify_user(user.id) And I made sure that it was saved in the database successfully in the table background_task I ran the command: python manage.py process_tasks The process keeps running without finding any task. With some troubleshooting, I found the part of the code that can't find any tasks in background_task/management/commands/process_tasks.py: while (duration <= 0) or (time.time() - start_time) <= duration: if sig_manager.kill_now: # shutting down gracefully break if not self._tasks.run_next_task(queue): # there were no tasks in the queue, let's recover. close_connection() logger.debug('waiting for tasks') time.sleep(sleep) else: # there were some tasks to process, let's check if there is more work to do after a little break. time.sleep(random.uniform(sig_manager.time_to_wait[0], sig_manager.time_to_wait[1])) It always doesn't find tasks in the queue (the second if statement). Any idea why it can't find a next task? I am pretty sure I'm going through the documentation step by step but now I am looking the library code and feeling getting out of track. -
Django + docker + periodic commands
What's the best practices for running periodic/scheduled tasks ( like manage.py custom_command ) when running Django with docker (docker-compose) ? f.e. the most common case - ./manage.py clearsessions Django recommends to run it with cronjobs... But Docker does not recommend adding more then one running service to single container... I guess I can create a docker-compose service from the same image for each command that i need to run - and the command should run infinite loop with a needed sleeps, but that seems overkill doing that for every command that need to be scheduled What's your advice ? -

With the json reponse that I am getting, there is a list of funding sources and within each funding source is an item that has the name with the object.

How to sum and group data for template
For simplicity, assume a database with the following columns: Table: Tickets Columns: Gender, Quantity, Date where Gender can be M or F. A row is inserted for every purchase. Ultimately I want a stacked bar chart that shows the quantity purchased by males and females each month. I can't seem to find a way to do this that doesn't require 2 queries, one that sums for M per month and one for F per month. The problem is that the query sets may not have the same number of objects and may not be in the same order by date. I've tried: set = Model.objects.filter(date__month = month).values('gender').aggregate(Sum('quantity')) This sorts by date but doesn't separate M from F. Adding M or F as a filter yields the correct quantity for one of the groups. Using two queries(one for each of M, F) yields the correct quantities and date ranges but doesn't necessarily yield an identical number of sets. (eg. if in some months there are no purchases by M). Thanks in advance for guidance. -
