ImportError: cannot import name 'setup_environ'
I am creating models in django environment. Below is the sample code. class Album(models.Model): artist = models.CharField(max_length=255) album_title = models.CharField(max_length=500) genre = models.CharField(max_length=255) logo = models.CharField(max_length=1000) def __str__(self): return self.album_title + ': ' + self.artist class Song(models.Model): artist = models.ForeignKey(Album, on_delete=models.CASCADE, null = True) file_type = models.CharField(max_length=255) song_title = models.CharField(max_length=255) def __str__(self): return self.song_title I was getting below error:: ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. So, I got some article that suggested me to import django module from django.core.management import setup_environ import settings setup_environ(settings) So now, the above error was corrected, but I got new error as below File "<ipython-input-8-3168a50cefba>", line 2, in <module> from django.core.management import setup_environ ImportError: cannot import name 'setup_environ' I know that the django module is present in my IDE, coz, when I hovered my cursor on the warning icon near the django module it said "django imported but not used". But that is not our concern, as I happened to get rid of the warning. Spyder IDE - 3.2.3 Python - 3.6 Django - 1.11.3-py36_0 -
Accessing the profile information of facebook through Django-Allauth
I am trying to display the complete profile of the authenticated user on my webpage using Django-allauth and Django 1.11.5. I am currently using a simple template as following: <html> <body> Welcome back {{ user.first_name }} <img src="{{cover.source}}" height="60" width="60"> <a href="/">Home</a> </body> </html> Here the image tag is not getting the data. Hence, getting a broken image. But I am wondering how I can use the Django Library and access the complete profile information of the visitor who get authenticated using the Django-Allauthlibrary. Here is the settings.py of my application:-- SITE_ID = 1 LOGIN_REDIRECT_URL = '/facebook_personality_traits/' SOCIALACCOUNT_QUERY_EMAIL = True SOCIALACCOUNT_PROVIDERS = { 'facebook': { 'SCOPE': ['email', 'user_posts', 'user_photos'], 'METHOD': 'js_sdk', 'FIELDS': [ 'email', 'name', 'first_name', 'last_name', ], 'EXCHANGE_TOKEN': True, 'VERIFIED_EMAIL': True, 'VERSION': 'v2.10', } } ACCOUNT_LOGOUT_ON_GET = True Kindly, help me. There are many misconceptions I am facing in the usage of the Django-Allauth. I specifically wants to access the Profile URL, Profile Picture, Posts, about me, etc. My Facebook Application has access to many scope, hence there is no problem for this, but the implementation of the library is restricting me from the usage. Kindly, help me. -
How do i find a lost element with jQuery
Well I have the problem, I can't log out when i just log in (without reloading the page). And I cant log in when I just logged out (again with page reload it works). Well I think after reloading the nav, he forgets the id of logout or something? <script> logout = $('#logout') loginform = $('#loginform') logout.click(function () { $.ajax({ url: 'accounts/logout/', success: function (json) { console.log(json) }); }, }); }); loginform.on('submit', function (event) { event.preventDefault(); login(); }); function login() { $.ajax({ url: 'accounts/login/', success: function (json) { console.log(json) /* Reloades the navbar */ $('#usergui').load(document.URL + ' #usergui'); } }); } ; </script> My HTML: <div id="usergui"> <ul class="nav navbar-nav navbar-right"> {% if user.is_authenticated %} <li><a id="logout"> </span> Logout </a></li> {% else%} <li><a> </span> Login </a></li> <li><a> </span> Register </a></li> {% endif %} </ul> </div> After Login my user gets authenticated and reloading the nav make only logout appear. -
Django Initial Value For Foreignkey Field
So I'm trying to pass some initial data to the volume field in CourseForm, but for some reason it won't work. I've tried looking at similar questions at stackoverflow, but no luck. The volume field is a ForeignKey to a table in the database. It doesn't give me errors just doesn't display any information. My model with the respective volume field: class Course(models.Model): volume = models.ForeignKey(CourseVolume) code = models.CharField(max_length=100, default=None) # ... code shortend to simplify My Modelform with its model set to Course class CourseForm(ModelForm): class Meta: model = Course fields = '__all__' My view where I'm trying to set the initial data for the CourseForm. It just doesn't seem to work. user.volume_preference returns an integer from 1-x which is the id for the specific volume. def view_course_create(request): if request.method == 'POST': form = CourseForm(request.POST) if form.is_valid(): form.save() return redirect('teaching_courses') else: user = MbsUser.get_user_from_ad(request.session['username']) if user.volume_preference is not None: volume = user.volume_preference form = CourseForm(initial={'volume': volume}) else: form = CourseForm() return render(request, 'teaching/course_create.html', {'form': form}) Anyone who knows how this can be solved? I've really looked and I'm at an impasse. Any help is greatly appreciated. -

How to disable queryset cache in Django forms?
I have a Django form that is supposed to filter choices using a queryset: class GenerateStudentAttendanceForm(forms.Form): selected_class = forms.ModelChoiceField(queryset=Class.on_site.filter( is_active=True, academic_year__is_active=True )) date = forms.DateField(initial=now().date()) The problem is that Class.on_site.filter is evaluated when the form is instantiated and is used for subsequent requests even if the site has changed. How can I come around this? -
Django1.8 or less queryset: filter multiple datetimes by hour
I have a model with a datetime field that I want to filter by hour, the problem is that there's multiple datetimes, making the datetime.now() soluction not realible for this case. Also, if we try gt/lt/gte/lte/in to the hour it doesn't work. The scenario is that if the hour is less then 12 then returns "morning", if it is between 12 and 18 returns "afternoon" and if it is greater then 18 returns "night". Model: class MyModel(models.Model): datetime_field = models.DatetimeField() name = models.CharField() Data example: 1. 2012/10/2 22:00 2. 2015/2/15 15:00 3. 2017/3/2 9:00 Expected queryset: Night = queryset.filter(datetime_field__hour__gte=18) Afternoon = queryset.filter(datetime_field__hour__lt=18, datetime_field__hour__gte=12) Morning = queryset.filter(datetime_field__hour__lt=12) Result: 1. Night 2. Afternoon 3. Morning -

Use include tag to include the same template that is calling it
I have a use case where different fields of a form are rendered differently based on an include tag and arguments passed to it. To keep it DRY, sometimes I'd like to include the same template and pass it a different argument, like in a simplified example below: main_form.html {% include "./field-snippet.html" with type=list %} field_snippet.html {% include "./field-snippet.html" with type="regular" %} But that gives a TemplateSyntaxError. Alternatively, I could have different html files for different kinds of fields but that seems to be many files with not much code in each. Any ideas on how to best approach this? Is using custom Widgets the best approach here (I haven't played much with them yet) -

Django url with anchor
I am using Django 1.11 and have troubles using urls with anchor. They work well intrapage, but when a url points to a specific anchor on another page it doesn't work at all. This is my url schema: url(r'^(?P<slug>[-_\w]+)/$', CategoryListView.as_view(), name='category_detail', ), And this is how the url is constructed: <a href="{{cat.get_absolute_url}}#someAnchor">BlaBla</a> Which results in a url that looks like this: mydomain.com/category/#venus As said once I get to the url at mydomain.com/category/ and reload retry (click again from a sidebar, no reload triggered) the page the anchor works, but when I am going from another location it doesn't point to the anchor and I end up on top of the page. Any ideas how to fix this? Thanks for any input. -

Django-Allauth does not offer posts extracts from profile
I am trying since weeks to get the users complete profile and posts for my NLP analysis. I have tried many libraries for that purpose and found Django-alluth a bit useful for authentication. But it does not satisfy my requirements including displaying the profile image, posts, about the user, etc. Inshort most part of the complete profiles on my website and then the analysis part using the posts text. I have gone through many libraries among which is Authomatic, django-allauth and many other. But they are useless in my case. I want to know how I can achieve this task in Django. I do not mean to use the JS-SDK of facebook, as it might reveal the program logic on the front. Kindly, suggest me. If anyone have better option for the achieving the task of my experiment. -

Django doesn't see some static files in development
I am having issues with django not serving some static assets during development. It's a really strange issue. This is how the pertinent part of my static directory is right now: site_media └── static ├── css │ ├── public.css │ ├── site-ada8eab0af.css Now that is my staticfiles directory, and things are correctly imported there from my static directory when I run manage.py collectstatic. I have two lines in my template: <link href="{% static 'css/site-ada8eab0af.css' %}" rel='stylesheet' /> <link href="{% static 'css/public.css' %}" rel="stylesheet" /> These produce these two lines in the rendered output: <link href="/site_media/static/css/site-ada8eab0af.css" rel='stylesheet' /> <link href="/site_media/static/css/public.css" rel="stylesheet" /> When I go to the first link, it works fine. When I go to the public.css link though, I get a 404 error that says 'css/public.css' could not be found. The complete link I use is http://localhost:8000/site_media/static/css/public.css What could possibly make it able to serve one of these files, but not the other? -
Django - Allauth - How to add additional API parameters to registration
I'm using Django all-auth through Django rest-auth and I'd like to extend the registratino functionality to match my custom user object.

In other words, what I want to be able to do, is call the /rest-auth/registration/ endpoint with a body like such; { "username": "foo", "email": "bar@mail.com", "password1": "fooBar!@", "password2": "fooBar!@", "first_name": "first", "last_name": "last" } and have first_name and last_name stored as a Profile object.
