Generate list of response messages in django-rest-framework
I'm creating an API using django-rest-framework. I intend to auto generate api clients for a couple of languages via openapi-generator from the openapi schema. django-rest-framework allows to generate an api schema through ./manage.py generateschema. Unfortunately the schema has (at least) two shortcomings: Responses don't have descriptions The schema shows response code 200 only Is there an obvious solution that I'm missing or do I have to adapt this this hack for django rest swagger from May 2017 somehow? This is the relevant code from a minimal application: #models.py from django.db import models class MyModel(models.Model): name = models.CharField(max_length=50) #serializers.py from rest_framework import serializers from . import models class MyModelSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = models.MyModel fields = ['name',] #views.py from django.shortcuts import render from rest_framework import viewsets from . import models, serializers class MyModelViewSet(viewsets.ModelViewSet): queryset = models.MyModel.objects.all() serializer_class = serializers.MyModelSerializer #./manage.py generateschema > schema.yaml ; cat schema.yaml paths: /mymodel/{id}/: delete: operationId: destroyMyModel responses: '200': content: application/json: schema: required: - name properties: name: maxLength: 50 type: string parameters: - name: id required: true in: path schema: type: string description: A unique integer value identifying this my model. put: operationId: updateMyModel responses: '200': content: application/json: schema: required: - name properties: name: maxLength: 50 type: … -
Run second Django for git pull
I use in my project(not my decision): python==2.7, Django==1.11.5, django-background-tasks==1.1.11 I want to update the server with git pull. I want to use a copy of the server to handle requests while the server restarts. How can I do this? How can I check that the tasks of runserver and background_tasks have ended? I'm new in CI and I don't know how to start and do it right. -
Axis / Key issues merging three dataframes into one
I'm trying to merge three (but really $n number of) dataframes of amortization tables into one table where the month is the primary axis. For instance a 360 month loan1 could start on May 1 2019, a 360 month loan2 could start on Sep 2 2019, and a 360 month loan3 could start on Jan 1 2019. When merging the dataframes the first column should be the first month across any of the dataframes and the last column should be the last month of the last month. I would expect blank or NaN values for months where a loan isn't active. When merging, I can't seem to get Months to be the Dataframe key. I have a function that grabs loans, builds amortization tables as dataframes, and puts them into a list. def buildLoanTable(): loans = Loan.objects.all() df=[] for l in loans: df.append(amortization_table(float(l.amount),float(l.rate),l.total_term/12, start_date=l.start_date)) for idx,d in enumerate(df): df[idx] = d.drop(columns=['Period']).T df = pd.concat(df, axis=1, ignore_index=True, sort=False) return df I've tried all sorts of variations of: df = pd.concat(df, axis=1, ignore_index=True, sort=False) df = pd.concat(df, axis=1, keys=(['Month']), ignore_index=True, sort=False) [ 0 1 2 ... 358 359 360 Month 2019-05-01 00:00:00 2019-06-01 00:00:00 2019-07-01 00:00:00 ... 2049-03-01 00:00:00 2049-04-01 00:00:00 2049-05-01 … -
How add custom fields to django-serializer dynamically?
I am trying to write a simple CRUD application. I have several pretty similar model classes and one serializer: class TestModelSerializer(serializers.ModelSerializer): queryset = None @classmethod def initialize(cls, queryset, context_class, **kwargs): _srlz = cls() _srlz.Meta.model = context_class _srlz.Meta.fields = '__all__' _srlz.queryset = queryset _srlz = cls(_srlz.queryset, **kwargs) return _srlz class Meta: model = None fields = '' so I can serialize my classes, calling initialize function like this: _q = Foo.objects.all() _srlz = TestModelSerializer.initialize(_q, Foo, many = True) _q2 = Bar.objects.all() _srlz2 = TestModelSerializer.initialize(_q2, Bar, many = True) and so on. But I have faced to one problem. Sometimes my classes are in hard One-to-Many relation (composition): class Foo(models.Model): pass class Bar(models.Model): foo = models.ForeignKey(Foo, on_delete = models.CASCADE) When I serialize Foo class I want to serialize a list of related Bar classes as well and nest result data to Foo's serializer data. I am not intended to write custom serializer for each of these classes but instead try to implement some generic approach. I decided to make some experiments and finally create an interface that provides me several methods for my collection items: class Foo(models.Model): bars = iCollection pass Now when instantiate a serializer I can get all fields of … -
How to call file object path in a django view?

Django generated time column
I am making a little Time Attendance Application in Django. I'm experimenting with models in my app. I can't figure out how I can do this: start_time datetime NOT NULL, finish_time datetime NULL, duration int(11) GENERATED AS (TIMESTAMPDIFF(MINUTE, start_time, end_time)) STORED NULL, In django. So far, I've made a table called employees with all the employees' details: class employees(models.Model): employee_id = models.AutoField(primary_key=True) first_name = models.CharField(max_length=15) last_name = models.CharField(max_lenth=20) user_pic_one = models.ImageField() user_pic_two = models.ImageField() user_pic_three = models.ImageField() age = models.IntegerField() national_id = models.CharField(max_length=15) join_date = models.DateField() pay_structure = models.CharField() What I want to do is, Make a new table that has the 5 columns. - employee_id (as a foreign key from the employees class we just made) - start_time = models.TimeField() - end_time = models.TimeField() - duration = models.IntegerField() - date = models.DateField(default=date.today) So the only two things that I want to know are: How to do the foreign key stuff to verify the employee id in the later table from the employees table. and calculate the time duration in minutes from the start_time to the end_time. Thanks :) -

Python - Is a dict or list better suited for efficiently storing and searching this data?
Here's the scenario: I'm parsing a log file and turning each individual line (string) from the log file into a hierarchical structure. I want to be able to categorize each message as belonging to a particular event on a particular day. I'm trying to send this data structure to the front-end of my Django app and display this hierarchical structure, and prevent the front-end from having to handle all these computations. On the front end I would like to be able to search by key words and display results that do this. Either I can search the data structure the back-end sends over, or I can search the rendered DOM. I have the following data: Day 1 Event 1 message message message Event 2 message message message Event 3 message message message Day 2 Event 1 message message message Event 2 message message message ...

Is it necessary to type in '$ pipenv install django==2.x.x' and '$ pipenv shell' everytime?
I'm reading 'Django for Beginners' by William S.Vincent to teach myself how to use the django framework and the author makes it seem like I have to type in '$ pipenv install django==2.x.x' and '$ pipenv shell' into the command line every time I launch PowerShell to use the framework. Is that necessary or is the author showing how one would normally start a django project for the first time and is this just a one-time command? -

Best practices for sharing database across multiple sites (specifically code versioning with schema changes)
We would like to run multiple django sites with the same codebase, but different versions due to different deploy dates, and would like to share a common content database. We are unsure how to deal with schema changes if all django server instances cannot be guaranteed to be updated at the same time. This is the beginning of the project, we current have one site and are looking to extend this to two sites, thereby introducing the problem. We foresee an issue if we make a schema change by updating the django code and running migrations on one site, but cannot deploy to the site for some time (due to deployment restrictions) that the other site would suffer because there would be a schema mismatch between the django expectation of the database structure and the actual database structure. Since we want to share a content database across multiple sites, we are looking for ways to solve this issue. We have considered having a local copy of the master content database for each site, which the master would replicate to in near real time. If there was a version mismatch then the older site would have the replication disabled. However then … -

Django prefetch_related and performance optimisation with multiple QuerySets within loops
Effectively I have multiple Queries within loops that I am just not happy with. I was wondering if someone had the expertise with prefetch_related and other Django Query construction optimisation to be able to help me on this issue. I start with: users = User.objects.filter(organisation=organisation).filter(is_active=True) Then, I start my loop over all days starting from a certain date "start_date": for date in (start_date + datetime.timedelta(n) for n in range((datetime.datetime.now().replace(tzinfo=pytz.UTC) - start_date).days + 1)): I then within this loop over a filtered subset of the above users for date in (start_date + datetime.timedelta(n) for n in range((datetime.datetime.now().replace(tzinfo=pytz.UTC) - start_date).days + 1)): for user in users.filter(created_date__lte=date).iterator(): Ok, so firstly, is there any way to optimise this? What may make some of the hardcore Django-ers loose their tether, I do all of the above inside another loop!! for survey in Survey.objects.all().iterator(): for date in (start_date + datetime.timedelta(n) for n in range((datetime.datetime.now().replace(tzinfo=pytz.UTC) - start_date).days + 1)): for user in users.filter(created_date__lte=date).iterator(): Inside the last loop, I perform one final Query filter: survey_result = SurveyResult.objects.filter(survey=survey, user=user, created_date__lte=date).order_by('-updated_date')[0] I do this because I feel I need to have the user, survey and date variables ready to filter...

How to encode an uploaded image using base64 and create a brand new PNG image by decoding it?
Currently, I created a Django html page that'll allow a user to upload an image. Images are restricted to only JPG, JPEG, PNG and SVG. If uploaded correctly, the image is stored as in a png extension. After this, I want to grab the path and encode it using base64. Using this string, I want to then create a brand new image which should hold a PNG extension and then store it in the database. How should I do this? Or better yet, is there a better way to do it?

Django middleware skipping data attribute in static url
i have a simple middleware builded in django app. It works for push notification image tracking. Logic: if push shows up, middleware should see it by data attribute and update status of my Push object. My middleware code: class PushStatistic: def process_request(self, request): if request.GET.get('pushid'): print('entered push id for readed') pushid = request.GET.get('pushid') print(f'Push id - {pushid}. Updating...') if pushid: pushid = int(pushid) if Push.objects.filter(id=pushid).exists(): Push.objects.filter(id=pushid).update(status=4) print('status updated') so when i send notification, icon url for push looks like this: https://test.com/static/img/pic.png?pushid=9403687 When push showing up, i see the picture, but middleware not working. I use the same middleware logic for push-clicks tracking, and it works well. I cant understand what im doing wrong now, cause as i see it, its just the same GET request. Maybe its because its static url? Also i build django-view with same logic for push tracking AND IN VIEW IT WORKS: def fileresp(request, filename): if request.GET.get('pushid'): pushid = request.GET.get('pushid') Push.objects.filter(id=pushid).update(status=4) image_data = open(f"{project_settings.BASE_DIR}/media/{filename}", "rb").read() return HttpResponse(image_data, content_type="image/png") But i want to build it in django-middleware for more universality.
