limit django fields queried in sql call to database by queryset
I have a table with a blob and would like to exclude it from being in the sql call to the database unless specifically called for. Out of the box django includes everything in the queryset. So far the only way I have found to limit the field is to add a function to the view get_queryset() def filter_queryset_fields(request, query_model): fields = request.query_params.get('fields') if fields: fields = fields.split(',') # Drop any fields that are not specified in the `fields` argument. allowed = set(fields) existing = set([f.name for f in query_model._meta.get_fields()]) values = [] for field_name in existing & allowed: values.append(field_name) queryset = query_model.objects.values(*values) else: queryset = query_model.objects.all() return queryset class TestViewSet(DynamicFieldsMixin, viewsets.ReadOnlyModelViewSet): queryset = models.TestData.objects.all() serializer_class = serializers.TestSerializer filter_backends = [django_filters.rest_framework.DjangoFilterBackend] filter_fields = ('id', 'frame_id', 'data_type') def get_queryset(self): return filter_queryset_fields(self.request, models.TestData) and mixin to the serializer to limit the fields it checks class DynamicFieldsMixin(object): def __init__(self, *args, **kwargs): super(DynamicFieldsMixin, self).__init__(*args, **kwargs) if "request" in self.context and self.context['request'] is not None: fields = self.context['request'].query_params.get('fields') if fields: fields = fields.split(',') # Drop any fields that are not specified in the `fields` argument. allowed = set(fields) existing = set(self.fields.keys()) for field_name in existing - allowed: self.fields.pop(field_name) class TestSerializer(DynamicFieldsMixin, rest_serializers.ModelSerializer): class Meta: model = … -

How to redirect Login link in Password reset complete Django
Login link in DJANGO admin directs the user to accounts/login rather than account/login. How do I solve this? Error: Using the URLconf defined in tutorial.urls, Django tried these URL patterns, in this order: [name='login_redirect'] admin/ account/ The current path, accounts/login/, didn't match any of these. urls.py: urlpatterns = [ path(r'', views.login_redirect, name='login_redirect'), path('admin/', admin.site.urls), path('account/', include('accounts.urls')), ] settings.py: LOGIN_REDIRECT_URL = '/account/' Thanks -
Django Window Function FirstValue Producing Invalid SQL
I'm trying to use a window function to get the first of each group and its producing the sql query below - I took the sql and played around with it in the console and it appears that the CAST() function is causing the issue. Is there a way to get rid of this in the query? Django 2,1 Code: def contract_list(user): price_window = Window( expression=FirstValue('settle_price'), partition_by=F('contract'), order_by=F('trade_time').desc() ) market_prices = Trade.objects.filter( contract__isnull=False ).annotate( market_price=price_window ).values( con=F('contract'), market_price=F('market_price'), ).order_by( 'contract' ).all() produces this SQL run on a SQLite3 database: SELECT CAST(FIRST_VALUE("trading_trade"."settle_price") AS NUMERIC) OVER PARTITION BY "trading_trade"."contract_id" ORDER BY "trading_trade"."trade_time" DESC) AS "market_price", "trading_trade"."contract_id" AS "con" FROM "trading_trade" WHERE "trading_trade"."contract_id" IS NOT NULL ORDER BY "trading_trade"."contract_id" ASC Again, the issue seems to be related to the CAST(FIRST_VALUE("trading_trade"."settle_price") AS NUMERIC) since removing the cast function produces a result set. -
Find the addresses of subpages with articles and collect the data from them
The goal of the task is to collect data from every article from the blog. The data should be collected by processing individual HTML documents returned by the blog. I started django project and write some scrapy code but I don't know how to create code that can find the addresses of subpages with articles and collect the data from them.

Pretty choices field for Django model
I am trying to develop a custom way to implement choices prettily for a Django model. I designed a class for choices and a custom field like this: class Choices: def __init__(self, *keys): self._keys = list(keys) def __getattr__(self, key): return self._keys.index(key) def __getitem__(self, index): return self._keys[index] def as_choices_list(self): return list(enumerate(self._keys)) class ChoicesField(models.PositiveSmallIntegerField): def __init__(self, *args, **kwargs): if isinstance(kwargs['choices'], Choices): kwargs['choices'] = kwargs['choices'].as_choices_list() super().__init__(*args, **kwargs) And my test model is: class MyModel(models.Model): TYPES = Choices('a', 'b', 'c') type = ChoicesField(choices=TYPES, default=TYPES.a) When I try to make a migration, I get the error: ValueError: 'contribute_to_class' is not in list This looks like I need to add some special implementation in my class Choices to make Django consider it as not a field. What is the best way to resolve my issue? -

What is the relation between 'add_form' and 'add_fieldsets' in the Django UserAdmin?
I have added a custom user model to Django (version 2.2) using the documentation on the Django website. While my code is working fine, I am having trouble understanding the correlation between 'add_form' and 'add_fieldsets'. Specifically, in my CustomUserCreationForm, I have only included 3 fields - 'mobile' (which is my username), 'email', and 'name'. In my add_fieldsets, I have included additional fields which I have defined in my model - 'account_name' and 'gender'. However, although the 'account_name' and 'gender' are NOT defined in my add_form, everything still works fine! Can somebody help me understand why? Read the documentation on https://docs.djangoproject.com/en/2.2/topics/auth/customizing/#using-a-custom-user-model-when-starting-a-project My Model: class CustomUser(AbstractBaseUser, PermissionsMixin, GuardianUserMixin): """ Customer user model which uses the user mobile number as the username. """ mobile = models.CharField( max_length=15, unique=True, verbose_name='user mobile number', help_text='mobile number with country code (without the +)', ) email = models.EmailField(max_length=50, blank=False) name = models.CharField('full name', max_length=50, blank=False) account_name = models.CharField('company', max_length=80, blank=False) gender = models.CharField('gender', max_length=6, blank=False) is_active = models.BooleanField('active', default=False) is_staff = models.BooleanField('staff status', default=False) date_joined = models.DateTimeField('date joined', default=timezone.now) objects = CustomUserManager() USERNAME_FIELD = 'mobile' EMAIL_FIELD = 'email' # Required fields only for the createsuperuser management command.

Prevent going back to previous page after page redirection if reload the page
I’m a social researcher and fairly new to web technology so I’m having few basic technical issues that I hope the community could help me with. I’m planning to provide online lessons and subsequently conduct some social experiments with the students. The lesson part is provided via smartsparrow https://www.smartsparrow.com/ The experimental part is implemented via Otree https://otree.readthedocs.io/en/latest/misc/django.html (it’s a Django library if I understand it correctly). I must put the experimental part into the lesson itself, which I can do this via the Iframe provided by smartsparrow. They have this very small library that help me to extract the info from smartsparrow to the webpage that is posted in their Iframe (https://github.com/SmartSparrow/simcapi-js). With this SimCapi library I was able to extract cohortId from smartsparrow to my Otree page. In Otree platform, I have separate URL for each cohortID from Smartsparrow. Thus, I made a simple Django html page with just a plain text saying students will be redirected shortly to their correct URL for their classroom. For redirecting, I simply used javascript: <script src='https://lib.smartsparrow.com/simcapi-js-3.1.0.min.js'></script> <script type="text/javascript"> var simModel = new simcapi.CapiAdapter.CapiModel({ coID: '34dsfd' }); simcapi.CapiAdapter.expose('coID', simModel, {alias: 'cohoID'}); simcapi.Transporter.addInitialSetupCompleteListener(init); function init(args) { cohortID = simcapi.Transporter.getConfig().cohortId; console.log(cohortID) simModel.set('coID', cohortID); var dict … -
What's the most efficient way to make a 5 tables join in django ORM?
database model I'm trying to get the inner join between contentprofile with contentaddresources to integrate easily with some system I wrote a raw query in django's ORM to get the desired result Query: select * from manager_contentaddresource cas inner join manager_contenttemplate ct on cas.content_template_id = ct.id inner join manager_mediaitem mi on mi.content_template_id = ct.id inner join manager_medialistitems mli on mli.media_id = mi.id inner join manager_medialist ml on mli.media_list_id = ml.id inner join manager_contentprofile cp on cp.media_list_id = ml.id where cp.id = 1 so is this an overhead? is there's more efficient way to do this join? thank you -

Django (DRF) fails to POST data to url with similar path
In my url conf I have two similar patterns: urlpatterns = [ path('chat/', views.chat), # create chat path('chat/message/', views.search), # create message ] The second path works as expect, however, when I try to POST data to chat/ I get error 405 and {"detail":"Method \"POST\" not allowed."} error message. The code in the view works, if I modify chat/ to something more specific like chat/create/ then everything works fine. However, this is not what I want to do. I thought django would match the first URL that matches the request. Why is this happening? It this bug or expected behavior? -
