DJANGO_SETTINGS_MODULE not recognizing my base module when starting a new project with Virtualenvwrapper
I am starting a new Django project with virtualenvwrapper, and for some reason django-admin does not recognize my settings module: $ mkproject djangotest (djangotest) $ pip install Django Collecting Django Using cached Django-2.0-py3-none-any.whl Collecting pytz (from Django) Using cached pytz-2017.3-py2.py3-none-any.whl Installing collected packages: pytz, Django Successfully installed Django-2.0 pytz-2017.3 (djangotest) $ django-admin The above command works and gives me the menu of django-admin subcommands. However, when I try to set DJANGO_SETTINGS_MODULE, my new djangotest app is not recognized: (djangotest) $ cd ../ (djangotest) $ django-admin startproject djangotest (djangotest) $ cd djangotest (djangotest) $ ls djangotest manage.py (djangotest) $ export DJANGO_SETTINGS_MODULE=djangotest.settings (djangotest) $ django-admin Traceback (most recent call last): File "/Users/sam/Dropbox/.virtualenvs/djangotest/bin/django-admin", line 11, in <module> sys.exit(execute_from_command_line()) File "/Users/sam/Dropbox/.virtualenvs/djangotest/lib/python3.6/site-packages/django/core/management/__init__.py", line 371, in execute_from_command_line utility.execute() File "/Users/sam/Dropbox/.virtualenvs/djangotest/lib/python3.6/site-packages/django/core/management/__init__.py", line 317, in execute settings.INSTALLED_APPS File "/Users/sam/Dropbox/.virtualenvs/djangotest/lib/python3.6/site-packages/django/conf/__init__.py", line 56, in __getattr__ self._setup(name) File "/Users/sam/Dropbox/.virtualenvs/djangotest/lib/python3.6/site-packages/django/conf/__init__.py", line 43, in _setup self._wrapped = Settings(settings_module) File "/Users/sam/Dropbox/.virtualenvs/djangotest/lib/python3.6/site-packages/django/conf/__init__.py", line 106, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/Users/sam/Dropbox/.virtualenvs/djangotest/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 941, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 994, in _gcd_import File … -
How to refer multiple model object using one model field in django?
Suppose, I have Project and Manager model. class Project(models.Model): name = models.CharField(max_length=50) class Manager(models.Model): name = models.CharField(max_length=50) projects = This would be array of Project object.

could not use custom templatetags in Django 2.0
I'm using Django 2.0. I have written few custom template tags to use in the template inside notes/templatetags/note_tags.py file where notes is app directory I have written few custom tags inside this file from django import template from django.template.defaultfilters import stringfilter from notepad.utils import simplify_text from notes.models import Note, ColorLabels register = template.Library() @register.filter(name='note_simplify') @stringfilter def note_simplify(value): return simplify_text(value) @register.filter(name='default_color_label') def default_color_label(): default_label = ColorLabels.objects.filter(default=True).first() print(default_label.value) return default_label and inside the template file, I have loaded the tag as {% load note_tags %} I'm able to use the first tag note_simplify but second tag default_color_label is not being called. I'm using both tags in the same file. One for modifying the passed data and another to simply print something # modify the note.content <p>{{ note.content|truncatechars:200|note_simplify }}</p> # to print some value {{ default_color_label.value }} I have also restared server many times. Is there something wrong? Why the tag is not being called in template? -

Pass date range in URL in Django Rest
I have a JSON structure like, [ { "date": "2017-12-17 06:26:53", "name": "ab", }, { "date": "2017-12-20 03:26:53", "name": "ab" }, { "date": "2017-12-18 04:26:53", "name": "ab" }, { "date": "2017-12-19 05:26:53", "name": "ab" } ] I am using Django Rest Framework. Whenever, I do a GET request to, localhost/namelist/{{name}}/ is returns the JSON where "name": "ab" . Now, I want to return JSON based on date range. I will pass the start date and end date in the url and it should return the value within that specific date range, time should be ignored. Also, we have to consider months also, not only dates. Here, in this example, month is same but in real scenario months might be different. Like, localhost/namelist/{{name}}/{{start_date}}/{{end_date}}/ If the URL is , localhost/namelist/abcd/2017-12-17/2017-12-19/ then it should return, [ { "date": "2017-12-17 06:26:53", "name": "ab", }, { "date": "2017-12-18 04:26:53", "name": "ab" }, { "date": "2017-12-19 05:26:53", "name": "ab" } ] views.py :- def get_queryset(self): param = self.kwargs.get('pk') param2 = self.kwargs.get('ak') return namelist.objects.filter(name=param, date = param2) urls.py :- urlpatterns = { url('^namelist/(?P<pk>[\w\-]+)/(?P<ak>[\w\-]+)/$', ListViewParam.as_view()), } I can pass the date in the URL, but what the recommended way to pass the date range ? -

Filtering many to many field Django
I have a query like this: queryset = User.objects.filter( ~Q(pk=self.request.user.pk), ~Q(connections_as_initiator__peer=self.request.user, connections_as_initiator__stopped=False)) Beetween one intitator and peer there could be numerous connections bun only one that is not stopped. So what I want this query to do is to find whether between the current user and the queried one there are active connections where the current user is a peer. But this is not what happens at all: SELECT accounts_user.id FROM accounts_user WHERE ( NOT accounts_user.id = 48 AND NOT accounts_user.id IN (SELECT U1.initiator_id AS col1 FROM connection U1 WHERE U1.peer_id = 48) AND NOT accounts_user.id IN (SELECT U1.initiator_id AS col1 FROM connection U1 WHERE U1.stopped = FALSE) ); What I was thinking of (and what gives an expected result) is something like: SELECT accounts_user.id FROM accounts_user WHERE ( NOT accounts_user.id = 48 AND NOT accounts_user.id IN (SELECT U1.initiator_id AS col1 FROM connection U1 WHERE U1.peer_id = 48 AND U1.stopped = FALSE) ); Is there a way to achieve that with ORM or should I start using raw SQL. I was also thinking about annotations, but I'm not yet 100% sure how to implement it that way. -

Call Rest API with user using Python requests
I want to call an API using requests.get() method where I have to give username and password as authentication like below. response = requests.get(url, auth=requests.auth.HTTPBasicAuth('username', 'password')) but I don't want to give password in auth as it will work dynamically where password will be encrypted. so is there any way to do this by only giving username and not password? -
Django error - 'function' object has no attribute 'MyForm'
I am new to Django and was working with Django forms and stuck at an error for which I am not finding any relevant solution. My Form.py is : from django import forms class MyForm(forms.Form): name = forms.CharField() email = forms.EmailField() text = forms.CharField(widget=forms.Textarea) and My views.py is : from django.shortcuts import render from django.http import HttpResponse from . import forms # Create your views here. def index(request): return render(request, 'basicapp/index.html') def forms(request): form = forms.MyForm() return render(request, 'basicapp/forms.html', context = { 'form' : form }) All the routing is Fine as I have checked by replacing forms with a normal HttpResponse but there is some problem in the forms.py or views.py as they the form in not being displayed in the browser and the Error is coming 'function' object has no attribute 'MyForm' Please Someone help :( I gotta move Forward -
