In Django Bootstrap 4, how to avoid rendering an alert with form errors?
I'm using django-bootstrap4 (https://django-bootstrap4.readthedocs.io/en/latest/) in a project and find that when there are errors in a form, an alert box shows up with a list of the errors. In my case, this is problematic because the errors are repeated: I've had a look at the FormRenderer source code, and I don't see a way I can opt out of displaying this 'alert of errors': class FormRenderer(BaseRenderer): """ Default form renderer """ def __init__(self, form, *args, **kwargs): if not isinstance(form, BaseForm): raise BootstrapError( 'Parameter "form" should contain a valid Django Form.') self.form = form super(FormRenderer, self).__init__(*args, **kwargs) self.error_css_class = kwargs.get('error_css_class', None) self.required_css_class = kwargs.get('required_css_class', None) self.bound_css_class = kwargs.get('bound_css_class', None) def render_fields(self): rendered_fields = [] for field in self.form: rendered_fields.append(render_field( field, layout=self.layout, form_group_class=self.form_group_class, field_class=self.field_class, label_class=self.label_class, show_label=self.show_label, show_help=self.show_help, exclude=self.exclude, set_placeholder=self.set_placeholder, size=self.size, horizontal_label_class=self.horizontal_label_class, horizontal_field_class=self.horizontal_field_class, error_css_class=self.error_css_class, required_css_class=self.required_css_class, bound_css_class=self.bound_css_class, )) return '\n'.join(rendered_fields) def get_fields_errors(self): form_errors = [] for field in self.form: if not field.is_hidden and field.errors: form_errors += field.errors return form_errors def render_errors(self, type='all'): form_errors = None if type == 'all': form_errors = self.get_fields_errors() + self.form.non_field_errors() elif type == 'fields': form_errors = self.get_fields_errors() elif type == 'non_fields': form_errors = self.form.non_field_errors() if form_errors: return render_template_file( 'bootstrap4/form_errors.html', context={ 'errors': form_errors, 'form': self.form, 'layout': self.layout, 'type': type, } ) … -
Django, JSON serialize queryset and list of models has different behavior
I have a Django model with a function (on the Python class) that modifies some of its fields. I can do this, and it works from django.core.serializers.json import DjangoJSONEncoder json.dumps(list(MyModel.objects.filter(...).values()), cls=DjangoJSONEncoder) Now I'd like to call the function MyModel.MyFunction on all the models before JSON encoding them. I've tried this, but obviously it returns the fields as they are in the database, not modified by MyFunction: from django.core.serializers.json import DjangoJSONEncoder mymodels = MyModel.objects.filter(...) for mymodel in mymodels: mymodel.MyFunction() # or mymodel.myfield = somethingelse json.dumps(list(mymodels.values()), cls=DjangoJSONEncoder) So I've tried this from django.core.serializers.json import DjangoJSONEncoder mymodels = MyModel.objects.filter(...) _mymodels = [] for mymodel in mymodels: mymodel.MyFunction() # or mymodel.myfield = somethingelse _mymodels.append(mymodel) json.dumps(_mymodels, cls=DjangoJSONEncoder) but TypeError: Object of type MyModel is not JSON serializable. I've read on other answers that you'd have to either install django rest framework or implement a to_json function on MyModel. However, I'd like not to clutter my application to achieve a behavior that is already available. How can I tell django to behave the same way on an array of models that it behaves on a queryset of the same model? -
Should I build my tuition website in Phoenix/Elixir
For background, I want to build a tuition site which can help tutors: Be found by students/parents and arrange lessons with said clients Organise their timetables with these students Teach online create my own plugins for the site (e.g. like a homework generator or something like that) Why Phoenix? From my research, even though it's new, it's very good at concurrency and hence should be very scalable if I manage to get a lot of tutors. It's also particularly fast which really sold me too. However, I've just come out of university with a BSci in Comp sci so it's my first proper deployable project. It's a really really enjoyable project (Functional languages are amazing) but I don't want my zeal to give me tunnel vision. I should also say, this is my own personal project that I want to build really to help students that I tutor. It is very fun learning phoenix, but I notice it's quite difficult to troubleshoot as it's not exactly the most popular framework. Stuff like ruby has a lot more tutorials and things like that. Nonetheless, from my surface-level research, phoenix feels perfect with its speed benchmarks. I'm a pretty capable programmer too. … -
Pagination in Django with two Querysets formatted in different ways
I want to get pagination to work with two separate query sets that are formatted in different ways. The first query set is smaller and will never be longer than the first page. The second query set is very long and will go on for 5 or 6 pages. The result content of both query sets are the same, but I format them in different ways in the html template. The models are exactly the same, Book and PremiumBook, except PremiumBook has lots more books (and contains all the elements in Book). I'll include the views.py and then the template: def servicesListView(request, category): model = Books table = Books.objects.filter(category=category) values_books = table.filter().values_list("serviceid") # remove these observations from next table. My next table is premium and not available to non-authenticated users new_table = PremiumBooks.objects.filter(category=category).exclude(bookid__in=values_books) new_table = new_table.filter().annotate(price_count=Count('premiumcost__price')).order_by('-price_count')[:60] page = request.GET.get('page', 1) paginator = Paginator(new_table, 5) try: new_table = paginator.page(new_table) except PageNotAnInteger: new_table = paginator.page(1) except EmptyPage: new_table = paginator.page(paginator.num_pages) return render(request, 'services/index.html', {'table': table, 'new_table': new_table}) Then, this is the template for the them: <main class="ui-book-list"> <div class="results-list grid-view"> <div class="container"> <h2>Book list </h2> <div class="grid-results-list book-list"> {% for book in table %} <div class="record"> <div class="content"> <h6> {{ book.easy_desc }} … -

Retrieve Data to Populate Table in Django
I have one view which renders a dropdown where a user will select an order number and direct them to another view where there should be a table which populates with all data related to that order #.

DRF - Add get_FIELD_display fields (AssertionError)

Cross validation in Django Admin between Parent and Child inline models
I have a Post model, which can contain either images or links to videos, or both. The requirement is that every Post must have at least one image or one link to video. My current problem is I don't know where to place the correct validation to make. I tried to override the functions add_view and change_view in PostAdmin but could not make it work. I also tried to make some validations in ImagenPostAdminFormSet and VideoLinkPostAdminFormSet, but were useless as either of them can be empty, but not both. Following is my code for the models: class Post(models.Model): .... nombre_post = models.CharField('Nombre del Posteo', max_length=255) descripcion = models.CharField('Descripción', max_length=255) .... class ImagenPost(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name="imagen_post") imagen_post = ContentTypeRestrictedFileField('Imagen del Posteo', upload_to=media_posteos, help_text='Formatos válidos: jpg, jpeg, gif, png') ... class VideoLinkPost(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name="video_link_post") video_link = EmbedVideoField('Link de Video', max_length=150, help_text='Ingresar Link de Video') ... Following the code for Admin: class ImagenPostAdminInline(admin.StackedInline): model = ImagenPost form = ImagenPostAdminForm formset = ImagenPostAdminFormSet extra = 1 class VideoLinkPostAdminInline(admin.StackedInline): model = VideoLinkPost form = VideoLinkPostAdminForm formset = VideoLinkPostAdminFormSet extra = 1 class PostAdmin(admin.ModelAdmin): form = PostAdminForm inlines = [ImagenPostAdminInline, VideoLinkPostAdminInline] As I said, the validation to make is that one … -

Issues with HyperlinkedModelSerializer with recursive model
Overview I'm setting up a new Django application with Django REST Framework (DRF), and this is my first time using the HyperlinkedModelSerializer for the API endpoint. I've overridden the get_queryset() method on the ModelViewSet, so I've also the basename argument to the application router and explicitly defined the url attribute in the serializer as suggested here. This fixed issues that I was having with the model's own url attribute. However, I'm getting the following error message when trying to serialize a ForeignKey field of the same class as the parent model. It fails with the following message: Could not resolve URL for hyperlinked relationship using view name "employee-detail". You may have failed to include the related model in your API, or incorrectly configured the lookup_field attribute on this field. Is there something special in the serializer I need to do to support using recursive model relationships like this? Example code # app/models.py from django.db import models class AbstractBase(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) class Meta: abstract = True class Employee(AbstractBase): name = models.CharField(max_length=254) manager = models.ForeignKey('self', related_name='direct_reports', on_delete=models.SET_NULL, blank=True, null=True) ... def __str__(self): return str(self.name) # app/views.py from rest_framework import viewsets from rest_framework.pagination import PageNumberPagination from app import models … -
Why doesn't Django have a simpler way to style form fields?
I've looked at a lot of different methods on how to style form fields and all of them seem to be pretty unideal. Especially when you're trying to use bootstrap. I've done it a few different ways and I'm just surprised there isn't a better method than any of these. Ex: Within the form file alias = forms.CharField(max_length=15, widget=forms.TextInput(attrs={'placeholder': 'Username'})) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['alias'].widget.attrs.update({'class': 'special'}) Ex: Doing it manually in the template as Django mentions (which I would rather not have to resort to doing) Ex: with the django-widget-tweaks package (got errors saying incorrect inputs when they definitely were correct) Is there another method or any instructions someone can point me to for what has worked well for them? Thanks. -
Python 2.7 and 3.7.2 compatible django-redis serializer
I'm trying to write a py2.7 - py3.7 compatible django-redis serializer. I'm using django-redis==4.8.0 with django==1.11.22 and the PickleSerializer. I saw this issue https://github.com/niwinz/django-redis/pull/279 on django-redis and wrote a serializer similar to what's said in the thread. However my object seems a little bit more complex? Not sure. My goal is to have 2 applications running at the same time, one with py2.7 and the other with py3.7. They have to be 100% compatible, and I'm not being able to get past this. Here is the code for the serializer: # -*- coding: utf-8 -*- import six from django.utils.encoding import force_bytes from django_redis.serializers.pickle import PickleSerializer try: import cPickle as pickle except ImportError: import pickle class CompatPickleSerializer(PickleSerializer): def loads(self, value): if six.PY3: return self._loads_py3(value) return super(CompatPickleSerializer, self).loads(force_bytes(value)) def _loads_py3(self, value): return pickle.loads( force_bytes(value), fix_imports=True, encoding='bytes' ) Example of object I'm trying to serialize: { 'created_at': datetime.datetime(2019, 7, 30, 20, 0, 29, 244916, tzinfo = < UTC > ), 'items': [{ 'unit_price': Decimal('3.00'), 'name': 'my item', 'id': '12312312', }] 'id': 'b5c6210d-561f-4e4e-a025-e55b39d95418', 'name': 'cart', 'customer': None, } The object is a lot bigger then that, but I assume that if I can do the flow with this object, I can do with a … -

Apache with Gunicorn proxy not serving /static Django files
As the title says, I'm having difficulty getting Apache setup correctly to serve Django static files in production with a Gunicorn proxy for the backend. I'm finding that when I switch DEBUG = False that the app quits working with: < unexpected token. Reading about it, it has to do with the use of STATIC_ROOT being incorrect. I have my STATIC_ROOT = os.path.join(BASE_DIR, 'static'), and I'm running python manage.py collectstatic which is collecting all the assets to /static in the project root. Then I run gunicorn wsgi -D in the same directory as wsgi.py.

Django Rest Framework: Nested Serializer lookup based on ForeignKey object?
I have a single CustomUser model which is shared by different type of profiles. One particular profile model allows users to have multiple Photos. class Profile(models.Model): user = models.OneToOneField(CustomUser, on_delete=models.CASCADE) ... other fields class Photo(models.Model): uuid = ShortUUIDField(unique=True, editable=False) user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) image = models.ImageField(blank=False, null=False) My API endpoint retrieves the profile model via the CustomUser id, this is easy to do. models.Profile.objects.filter(user=user) What confuses me is how to reference the CustomUser model for the nested Photo serializer to retrieve all the user photos. All the examples I've managed to lookup use a field from the parent model as lookup but I need to use a child model field as lookup here. Here's what I've tried so far: class PhotoSerializer(serializers.ModelSerializer): class Meta: model = models.Photo fields = "__all__" class ProfileSerializer(serializers.ModelSerializer): photos = PhotoSerializer(many=True,read_only=True) class Meta: model = models.Profile fields = "__all__" Thanks! -
How to convert an uploaded file (InMemoryUploadedFile) from pdf to jpeg in Django using wand?

when I tried using Django-intl-tel-input it didn't work so how can I set a relative path to the images as in the documentation in this question I showed my template and my terminal log 3.Override the path to flags.png in your CSS .iti__flag {background-image: url("path/to/flags.png");} @media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) { .iti__flag {background-image: url("path/to/flags@2x.png");} } can I use Django's/python's template tags like {static 'images/flags@2x.png' } or should I just use the images inside the CSS file directory? so how can I set this with Django so I don't need to change the path when I deploy the project on a server? -
Users are not automatically logged in to social-auth-app-django
I configured user authorization via GoogleOauth2.0 (social-auth-app-django). Entries in the social_django / usersocialauth / application are created. Also created user profiles in accounts / user /. But for some reason there is no automatic login. What could be the reason? As I understand it, this is due to the fact that the user has is_active = False (I redefined BaseUser). Is it possible to somehow intercept user authorithation through social_django to set their status as is_active = True. Only signals come to mind. settings.py MIDDLEWARE_CLASSES = ( 'django.contrib.auth.middleware.AuthenticationMiddleware', 'social_django.middleware.SocialAuthExceptionMiddleware', ) TEMPLATES = [ { 'OPTIONS': { 'context_processors': [ 'social_django.context_processors.backends', 'social_django.context_processors.login_redirect', ], SOCIAL_AUTH_PIPELINE = ( 'social_core.pipeline.social_auth.social_details', 'social_core.pipeline.social_auth.social_uid', 'social_core.pipeline.social_auth.auth_allowed', 'social_core.pipeline.social_auth.social_user', 'social_core.pipeline.social_auth.associate_by_email', 'social_core.pipeline.user.get_username', 'social_core.pipeline.mail.mail_validation', 'social_core.pipeline.user.create_user', 'social_core.pipeline.social_auth.associate_user', 'social_core.pipeline.social_auth.load_extra_data', 'social_core.pipeline.user.user_details', ) INSTALLED_APPS = ( #...

Single quote inside double quote is messing up javascript code
I'm building a Django web app and I'm trying to send a JSON object to my javascript code using a Django template variable. # views.py import json def get_autocomplete_cache(): autocomplete_list = ["test1", "test2", "test3", "test4 - don't delete"] return json.dumps(autocomplete_list) <!-- html page --> <script> // Things i've tried autocomplete = {{ autocomplete_list|safe }}; autocomplete = '{{ autocomplete_list|safe }}'; autocomplete = JSON.parse('{{ autocomplete_list|safe }}'); </script> If I wrap {{ autocomplete_list|safe } in single quotes like '{{ autocomplete_list|safe }}', then the single quote in test4 - don't delete messes up the variable and Uncaught SyntaxError: Unexpected identifier. However, if I leave it as {{ autocomplete_list|safe }}, then the HTML text highlights it as an error with red underlines. What am I doing wrong here? -
