Where in Django code put code disconnecting signal and doing monkey-patching?
I'm working on custom authorization backend for Django 2.2. I don't want django to update last_login for user so I wanted to disconnect signal user_logged_in from triggering update_last_login. I also have to do monkey patch in SimpleJWT library changing User to point OtherUserModel Where is the best place to put this code? For now, I have added in CoreConfig.ready method and it works but is it a good place for this logic? from django.apps import AppConfig class CoreConfig(AppConfig): name = 'core' def ready(self): from django.contrib.auth import user_logged_in from django.contrib.auth.models import update_last_login user_logged_in.disconnect(update_last_login, dispatch_uid='update_last_login') import rest_framework_simplejwt.state rest_framework_simplejwt.state.User = OtherUserModel -
Showing the uploaded csv file on Django template
I have a project that accepts an uploaded .csv file and shows it on the admin via the models.py. What I want to happen is to show these uploaded .csv file on the template. my views are: def data_upload(request): template = "home.html" if request.method == 'GET': return render(request, template) csv_file = request.FILES['file'] if not csv_file.name.endswith('.csv'): messages.error(request, 'Please upload a .csv file.') data_set = csv_file.read().decode('ISO-8859-1') io_string = io.StringIO(data_set) next(io_string) for column in csv.reader(io_string, delimiter=','): _, created = Table.objects.update_or_create( page=column[0], keyword=column[1], interval=column[2], email=column[3], notes=column[4], billing=column[5], ) context = {} return render(request, template, context) The views are already working when I upload the .csv file. On the home.html file, this is what I did: <table class="table table-condensed"> <thead> <tr> <th>...</th> </tr> </thead> <tbody> <tr> <th class="center-align" scope="row"><i class="small material-icons green">check</i></th> {% for t in tables %} <td class="center-align">{{t.page}}</td> <td class="center-align">{{t.keyword}}</td> <td class="center-align">{{t.interval}}</td> <td class="center-align">{{t.email}}</td> <td class="center-align">{{t.notes}} </td> <td class="center-align">{{t.billing}}</td> {% endfor %} </tr> </table> How do I properly iterate on the template to show what I uploaded on my html file? -
Django runserver not running when importing another python file
I'm new to Django, so I am trying to import a python file in the views.py inside my Django app. When I run the server with python manage.py runserver it's not doing anything. When I comment out the import part it works for some odd reason I've already tried some solutions. Like: import [file] from . import [file] from .[file] import [function in the file] and all these still didn't work. DETAILS: -Python version 3.7.3 -Django version 2.2.5 CODE: Note: this is in views.py import bot def process(request): username = request.POST["username"] email = request.POST["email"] code = generate_code(random.randrange(5, 12)) data = {"username": username, "email": email, "code": code} bot.say("Hi", channel_id=600617861261819906) return render(request, "process.html", data) -
Unit Testing - Get Request that includes JSON-data
I´m currently creating Unit-Tests for existing endpoints. I have a GET-Request Endpoint to whom I send JSON Data is a kind of filter parameters. By using Postman everything works well. When I create the Unit-Tests the JSON Parameters are not used. In the documentation I saw that data in the request is send as Parameter in the URL. But that is not working for me. Thanks in advance! Checked the django documentation Views.py def get_queryset(self): return self.model.objects.filter( **{ field + '_id': self.request.data[field] for field in ['post', 'user', 'product'] if field in self.request.data } ).order_by( '-time_stamp' ) Unit Test response = self.client.get( "/api/v1/post/get_clicks_stats/", data={ "user": "5b1d4efa-09e1-4a29-ba50-314d34cd50f0", } ) self.assertEqual(response.status_code, 200) self.assertEqual(response.json()['count'], 1) -

Running manage.py shell with -c flag within docker-compose run
I want to run a script that runs Django code in my docker container. My initial plan was to run the following: docker-compose run web python manage.py -c "import django; print(django.__version__)" However, that isn't working: it prompts manage.py shell: error: unrecognized arguments. I guess it has to do with the fact that -c is a flag shared both by manage.py and by bash, or at least that's what I gathered from the docker-compose docs and Django's. If I run docker-compose run web bash, it prompts the shell, where I can do python manage.py shell -c "...". How can I do that in just one step? Any help is much appreciated. -

Effective ways of reusing python-request in function for internal api calls
I'm using python request lib for internal calls in our Django app. we have many helper functions for such internal calls. The problem with this approach is we are repeating the same function for different internal calls. Differences being request_url, request_data, request_response(tuple/list/dict). We are using the following function for internal calls, the same function is used for different calls based on the difference in input data, URL and response. for ex: get_data_from_service1, get_data_from_service2 etc def get_data_from_service(data): request_url = BASE_URL + "api/post/service/" request_data = rqt.get_service_request_translator(data) try: request_response = requests.post(url=request_url, data=request_data) except requests.exceptions.RequestException as ex: logger_excp.exception(str(ex)) return error_msg.UNABLE_TO_REACH_SERVICE if request_response.status_code == 200: models_data = request_response.json().get("data") total_count = request_response.json().get("total_count") return models_data, total_count elif request_response.status_code == 500: logger.error(request_response.text) return error_msg.PROBLEM_WITH_SERVICE else: logger.error(request_response.text) return error_msg.SOMETHING_WENT_WRONG please help with the following points. What would be an effective way of not repeating function everywhere should something like a base class be used? How to handle timeouts at global(base class/factory function?) and local functions? for ex: a base class/function having a timeout of say timeout=5 while local function having a timeout of timeout=2 or no timeout at all. how to change the error response of such functions. say for example if I want to raise an exception instead … -

Django query OneToMany by multiple fields

The query I wrote will find all people with a pet named rex, and a vaccinated pet (not necessarily the same pet..) Is there a way to query with multiple conditions on the same OneToMany relation? P.S the real query I'm trying to write is more similar to the following: Person.objecs.filter(pet__class1__date__isnull=False, pet__class1__class2__class3__name="blabla") where I want to reach class 3 only through class1 instances that their date is not null -

How to extend django UserCreationForm model to include phone number field
I cant seem to find any posts here regarding extending the Django UserCreationForm model to include a phone number field for users to enter their number and then validate the phone number using phonenumbers.parse in the backend to check if the number is in the respective format and whether it exists or not. I need to know what code I should include in my forms.py under my "users" app. I've tried including normal html text field for the phonenumbers and it does not belong to the default UserCreationForm model in Django and neither can it be stored in the database.

I am only using forms.py, views.py and register.html to be rendered in views as shown below, currently I am not using models.py. /* forms.py */ from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm # from validate_email import validate_email class UserRegisterForm(UserCreationForm): email = forms.EmailField() phone_number = forms.IntegerField(required=True) class Meta: model = User fields = ['username', 'email', 'password1', 'password2'] def save(self, commit=True): user = super(UserCreationForm, self).save(commit=False) user.email = self.cleaned_data['email'] if commit: user.save() return user /* views.py */ from django.shortcuts import render, redirect from django.contrib import … -

Django: Is there a way to specify key_name of MySql index in migrate?
There is the following model, and you are trying to set index_together. class Event(models.Model): class Meta: ordering = ["-id"] index_together = ["user", "action"] action = models.IntegerField(db_index=True) user = models.ForeignKey("users.User", on_delete=models.CASCADE) post = models.ForeignKey("posts.Post", null=True, on_delete=models.CASCADE) When python manage.py makemigrations is executed, the following migration file is generated class Migration(migrations.Migration): dependencies = [ ('users', '00xx_auto_yyyymmdd_hhmm'), ('events', '00xx_auto_yyyymmdd_hhmm'), ] operations = [ migrations.AlterIndexTogether( name='event', index_together=set([('user', 'action')]), ), ] SHOW INDEX FROM tbl_name; in MySQL, index is assigned.

Below is the query: db.createUser( { user: "username", pwd: "password", roles: [ { role: "readWriteAnyDatabase", db: "admin" } ] } ) I am trying to authenticate to MongoDB with pymongo on my local system but getting the below error: I am using the below configurations: pymongo==3.5. python 3.6.8 Django==1.11.7 MongoDB version v4.2.0 Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x7fb6c2b776a8> Traceback (most recent call last): File "/home/akash/Documents/Python/project/env/lib/python3.6/site-packages/django/utils/autoreload.py", line 228, in wrapper fn(*args, **kwargs) File "/home/akash/Documents/Python/project/env/lib/python3.6/site-packages/django/core/management/commands/runserver.py", line 147, in inner_run handler = self.get_handler(*args, **options) File "/home/akash/Documents/Python/project/env/lib/python3.6/site-packages/django/contrib/staticfiles/management/commands/runserver.py", line 28, in get_handler handler = super(Command, self).get_handler(*args, **options) File "/home/akash/Documents/Python/project/env/lib/python3.6/site-packages/django/core/management/commands/runserver.py", line 68, in get_handler return get_internal_wsgi_application() File "/home/akash/Documents/Python/project/env/lib/python3.6/site-packages/django/core/servers/basehttp.py", line 47, in get_internal_wsgi_application return import_string(app_path) File "/home/akash/Documents/Python/project/env/lib/python3.6/site-packages/django/utils/module_loading.py", line 20, in import_string module = import_module(module_path) File "/home/akash/Documents/Python/project/env/lib/python3.6/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 994, in _gcd_import File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 955, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 665, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 678, in exec_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "/home/akash/Documents/Python/project/Web/project/project/wsgi.py", line 16, in <module> application = get_wsgi_application() … -

Django/DRF filtering
I filter my list of Product models by title field. For example, I want to find this title = 'Happy cake'. And if I type Case 1. 'happy cake', Case 2. 'hapy cake', happi kake' it should return me 'Happy cake'.As I know icontains helps me with case 1. How can I get that?May be some sort of technologies should be added or django itself has appropriate solution?
