why connection.timezone is None for postgres db connection in django?
I am exploring django with postgres. I have encountered a strange thing. TIMEZONE setting for my postgres connection(I am not talking about TIME_ZONE in settings.py) is surprisingly set to None. I have set timezone to 'Asia/Kolkata' and USE_TZ is also True. As per django docs, when USE_TZ is True, the connection timezone 'UTC' by default, while it'll be equal to the value of TIME_ZONE in settings.py, when USE_TZ is False. But, for me in both the cases, the value of connection.timezone is empty. I have tried with sqlite3 backend, where I am getting expected results. I don't know, why I am not getting expected behaviour with postgres. I am using django==1.10.5 and postgres is 9.5 on 64 bit machine. I am using following command to get connection's timezone. from django.db import connection print (connection.timezone) Thanks in advance. -

Django admin edit integer field
I have a model with two integer fields which are supposed to be foreign keys. In my admin view, those two fields are editable but I would like to display a search icon next to the field, so I can retrieve the id of another model and append to the field. Does django have this feature? class Linkage(models.Model): user_id = models.IntegerField(default=1) parent_id = models.IntegerField(default=0) -

Exclude objects whose date time field values are greater than the current date and time
I have a class To Do and it has a dead line property. class ToDo(models.Model): ... ... dead_line = models.DateTimeField() user = models.ForeignKey(User, on_delete=models.CASCADE) I would like to get all the to-do's except for the to-do's whose dead line value has crossed current date and time. I tried this way: to_do_list = user.todo_set.all().exclude(dead_line__lte=datetime.now(pytz.timezone('Asia/Kolkata'))) But, this gives me all the to-dos. Again, this works just fine and excludes the to-do's which are of current day: to_do_list = user.todo_set.all().exclude(dead_line__day=datetime.now(pytz.timezone('Asia/Kolkata')).day) What am I doing wrong? How can I get all the to-do's whose dead line is greater that current date and time? -
How to filter JSON Array in Django JSONField
i am getting crazy with filtering a (postgres) JSONField in Django 2.0.3. The json is stored as an array. E.g. tasks = [{"task":"test","level":"10"},{"task":"test 123","level":"20"}] What i've tried: myModel.objects.filter("tasks__task__contains"="test") myModel.objects.filter("tasks_task__0__contains"="test") myModel.objects.filter("tasks__0__task__contains"="test") myModel.objects.filter("tasks_task__0_x__contains"="test") myModel.objects.filter("tasks__0_x__task__contains"="test") What goes wrong?

only one form's submit button working
I have two include statements in my html- {% include "abc_bs3.html" with form=form form_title="Edit" form_btn="Save" form_id="edit" ajax="True" %} {% include "abc_bs3.html" with form=form2 form_title="Add" form_btn="Add" form_id="add" ajax="True" %} So, essentially- two forms on one page.

CSRF is only checked when authenticated in DRF?
I'm starting to build a django rest framework API for a react application, and we want everything, including the authentication, to be handled via API. We are using SessionAuthentication. If I have an authenticated session, then CSRF works entirely as expected (when auth'd the client should have a CSRF cookie set, and this needs to be paired with the csrfmiddlewaretoken in the POST data). However, when not authenticated, no POSTs seem to be subject to CSRF checks. Including the (basic) login APIView that has been created. This leaves the site vulnerable to login CSRF exploits. Does anyone know how to enforce CSRF checks even on unathenticated sessions? and/or how DRF seems to bypass CSRF checks for login? settings.py: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.SessionAuthentication', ], 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated', ], } views.py: class Login(APIView): permission_classes = (permissions.AllowAny,) @method_decorator(csrf_protect) # shouldn't be needed def post(self, request, format=None): user = authenticate( request, username=request.POST['username'], password=request.POST['password'] ) # ... perform login logic ... def get(self, request, format=None): """ Client must GET the login to obtain CSRF token """ # Force generation of CSRF token so that it's set in the client get_token(request) return Response(None) urls.py: urlpatterns = [ url(r'^login/$', views.Login.as_view(), name='login'), ] expected behaviour: login_url … -

Django Python Requests - Parse text/plain payload
This seems like a stupid question, and probably is. Say that I'm making a request to an API as follows: r = requests.post("http://EXAMPLE.COM/api/randomstring") ## I've blocked out the real URL so false requests aren't made as it's publicly available The specification for this API is that on every request, it generates a random string of 10 letters. If the request is processed successfully, the server should respond with 201 CREATED and a text/plain payload giving the random string from the API database. I have previously tried the following to parse the request, and add it to a locally stored database model: new_word = r.text() Words.objects.create(word=new_word) But this gave the error: TypeError: 'str' object is not callable I then tried simply: Words.objects.create(word=r) When I run this from a client, and then check the local database, it only shows as: word: <Response [201]> This means that obviously the request was successful, and a word is in the text/plain payload. But how do I parse only the word from the payload, so that I am able to save it as (for example): word: hskcudyhft I know how to parse a JSON payload which is probably much trickier than this - which is probably … -

Fail sending mail with Django

How to create backbone of my Django web-application
I have the following problem. I am building a calculation web application using Django. The app will have the following models: User Project ( a user will have one or more projects) System (a project has one or more hydraulic systems) Circuit (a system will have one or more hydraulic circuits) Component (a hydraulic circuit will have one or more hydraulic components) How should I organize my code. Should I create 5 different apps? How to organize my urls.py for the various apps? Basically the problem seems to be that there are 5 nested models. I already implemeted user and project. Currently the mysite.urls is something like: urlpatterns = [ path('', include('core.urls')), # handles the User path('project/', include('project.urls')), path('admin/', admin.site.urls), ] The project.urls is given by: app_name = 'project' urlpatterns = [ path('', views.ProjectIndexView.as_view(), name='index'), path('create/', views.ProjectCreateView.as_view(), name='create'), path('create_project/', views.create_project, name='create_project'), path('<int:pk>/', views.ProjectDetailView.as_view(), name='detail'), path('<int:project_id>/change_project/', views.change_project, name='change_project'), path('<int:pk>/results/', views.ProjectResultsView.as_view(), name='results'), path('<int:pk>/delete_project/', views.ProjectDeleteView.as_view(), name='delete_project') ] So far so good, but how should I next configure the urls to include the System model?

Passing a matplotlib image to render via context in Django
I am trying to render a call to a query, some text and a matplotlib image on a webpage using Django. I have the following views.py file: def getinput(request): if request.method == 'POST': form = get_data(request.POST) if form.is_valid(): down = form.cleaned_data['get_down'] ytg = form.cleaned_data['get_ytg'] yfog = form.cleaned_data['get_yfog'] map_data = next_play.objects.filter(last_dwn__exact=down, last_yfog__exact=yfog, last_ytg__exact=ytg) fig = plot_playoutcomes(map_data) context = {'form': form, 'query_data': map_data, 'img': fig} return render(request, 'play_outcomes/output.html', context) else: form = get_data() return render(request, 'play_outcomes/getinput.html', {'form': form}) This calls a query from my model that it stores in map_data. I then want to plot an image and call plot_playoutcomes(map_data). Here is the code for that: from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas from matplotlib.figure import Figure import numpy as np from django.http import HttpResponse, HttpResponseRedirect def plot_playoutcomes(playdata): fig = Figure() canvas = FigureCanvas(fig) ax = fig.add_subplot(111) x = np.arange(-2,1.5,.01) y = np.sin(np.exp(2*x)) ax.plot(x, y) response = HttpResponse(content_type='image/png') canvas.print_png(response) return response Note - that in the function I DO NOT use map_data, but rather plot a simple picture.
