django admin automatic rtl for some languages
I'm trying to add multi language support for a django project using Django i18n official documentaion: https://docs.djangoproject.com/en/4.1/topics/i18n/translation/ When I change the LANGUAGE_CODE to something like 'fa', by default the admin panel changes to RTL. But the problem is when I use other RTL languages like 'ku' (kurdish) the page remains in ltr. I know we can change the css manualy, but wonder what is the problem here and how some languages like Arabic or persian does the RTL part automaticaly but others dont. Thanks in advance # settings.py LANGUAGE_CODE = 'en-us' USE_I18N = True USE_L10N = True TIME_ZONE = 'UTC' USE_TZ = True LANGUAGES = ( ('en', _('English')), ('ku', _('Kurdish')), ('fa', _('Persian')), ) LOCALE_PATHS = [ Path(BASE_DIR, 'django_i18n', 'locale'), ] # url.py urlpatterns = i18n_patterns( path('admin/', admin.site.urls), ) +static(settings.MEDIA_URL, document_root= settings.MEDIA_ROOT) -
Update view in Django WITHOUT using generic classes
I think I don't understand something fundamental here, but every single tutorial on the topic proposes a solution using either a function or a generic class, and both of them work for me, but I can't figure out how to deal with the issue using just View. So to illustrate where I am at, I am building a very simple blog and want to update data on a single post based on it's id. So what I have is: models.py class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() author = models.CharField(max_length=100) def __str__(self): return self.title def get_absolute_url(self): return reverse('post-detail', kwargs={'pk': self.pk}) forms.py class PostForm(forms.ModelForm): class Meta: model = Post fields = '__all__' urls.py urlpatterns = [ path('post/<int:pk>/update/', PostUpdateView.as_view(), name='post-update') ] update_post.html <form method="post"> {% csrf_token %} {{ isolated_post.as_p }} <input type="submit" value="Update"> </form> and finally views.py class PostUpdateView(View): form_class = PostForm initial = {'key': 'value'} template_name = "blog/update_post.html" def get(self, request, pk): isolated_post = Post.objects.get(pk=pk) form = self.form_class(instance=isolated_post) return render(request, self.template_name, {'form': form}) def post(self, request, pk, form): updated_post = self.form_class(request.POST, instance=form) if updated_post.is_valid(): updated_post.save() return HttpResponseRedirect("/post/" + f'{pk}/') return render(request, self.template_name, {'updated_post': updated_post}) I've tried a lot of things, this time it says that form has not been passed … -

javascript download docx file from ajax response
I have a django function with return: ... return FileResponse(open('demo.docx', 'rb')) I use ajax to get it on client side. Now I need to download it on client side. I use this code: ... success:function(response){ var blob = new Blob([response]); var link = document.createElement('a'); link.href = window.URL.createObjectURL(blob); link.download = "file.docx"; link.click(); }, ... Edited: function func(){ var csrftoken = $("[name=csrfmiddlewaretoken]").val(); $.ajax({ type: 'POST', url: '/myapp/func/', headers:{ "X-CSRFToken": csrftoken }, data: {name:"",'image1': Data1}, success:function(response){ var blob = new Blob([response]); var link = document.createElement('a'); link.href = window.URL.createObjectURL(blob); link.setAttribute('target', '_blank'); link.download = "file.docx"; link.click(); }, error : function(xhr,errmsg,err) { alert("ajax error: func"); } }); } However it downloads a corrupt something, probably not a docx file. How can I get on client side what I read as a docx? -

Custom rendered input for django-formtools wizard field
New to Django. I've created some bootstrap card UI widgets that function as radio buttons and this works ok in plain old html, but I'm trying to integrate it into a Django wizard. How would I go about telling the form the data field is associated with? I just have a bunch of widgets included for each option like this <div class="col-6"> {% include "./domain_type_widget.html" with radio_group="domain_type" title="People" description="For a URL with your name" left="name" mid="people" type_id="name" checked=True %} </div> <div class="col-6"> {% include "./domain_type_widget.html" with radio_group="domain_type" title="Event" description="For events" left="eventname" mid="event" type_id="event" %} </div> And domain_type_widget.html looks like so <label class="card m-1 {% if checked %}selected_type{% endif %}" id="{{ type_id }}_card"> <div class="card-body" onclick="selectDomainType({{type_id}})"> <div class="row"> <div class="col-sm-12 col-md-10"> <h5 class="card-title">{{ title }}</h5> <p class="card-text">{{ description }}</p> {% if left %} <p class="domain-example" class="domain-example"> <span class="left">{{ left }}</span> <span>.</span> <span class="mid">{{ mid }}</span> <span>.</span> <span class="right">site.com</span> </p> {% endif %} </div> <div class="col-sm-12 col-md-2 d-flex align-items-center justify-content-center"> <input type="radio" class="radio" name="{{ radio_group }}" id="{{ type_id }}" {% if checked %}checked{% endif %} onchange="selectDomainType(this)"> </div> </div> </div> -
How do you use the Django timezone.override(utc) to create datetimes with tzinfo?
I can use timezone.now() to get a UTC timestamp in Django. I can use timezone.make_aware(datetime(2012,1,1)) to add UTC as the TZ for the datetime. Last one is cumbersome and a lot of extra typing. Meanwhile I find these docs: https://docs.djangoproject.com/en/4.1/topics/i18n/timezones/ But activating the TZ doesn't seem to affect datetime creation (still no tzinfo included) I also found these docs inside python: >>> from django.utils import timezone >>> help(timezone) Help on module django.utils.timezone in django.utils: NAME django.utils.timezone - Timezone-related classes and functions. CLASSES contextlib.ContextDecorator(builtins.object) override class override(contextlib.ContextDecorator) | override(timezone) | | Temporarily set the time zone for the current thread. | | This is a context manager that uses django.utils.timezone.activate() | to set the timezone on entry and restores the previously active timezone | on exit. | | The ``timezone`` argument must be an instance of a ``tzinfo`` subclass, a | time zone name, or ``None``.

Show another static content as part of Django page
Collaborator is giving me static content that I'd like to display as a component of a page in a Django app. I'd like to do this without styling interruptions. Specifically: I have a Django template templates/page.html that extends templates/base.html. The base.html includes header/footer/navbar/etc. In the middle of page.html, I'd like to insert external HTML (with its own CSS) exactly as being imported, so that external CSS styling in templates/base.html doesn't get applied. (But I also don't want the CSS I am importing to affect stuff in base.html either.) Is there a Django-native, or HTML/CSS-native way to accomplish this? -

Iterate over page data stored in a settings Orderable
I have created a Wagtail settings page that allows me to select 1-5 pages which I'd like to display in my site footer as 'Most popular pages'. I've done this using an Orderable and PageChooserPanel, see below: @register_setting class MostPopularPosts(BaseSetting, ClusterableModel): display_most_popular_posts_in_sidebar = models.BooleanField("Display most popular posts in sidebar", default=True, help_text='Untick to hide the most popular posts widget') panels = [ FieldPanel('display_most_popular_posts_in_sidebar'), InlinePanel('popular_pages', max_num=5, min_num=1, label="Most popular pages"), ] class MostPopularPostPages(Orderable): settings_page = ParentalKey(MostPopularPosts, related_name="popular_pages") popular_page = models.ForeignKey( 'wagtailcore.Page', null=True, blank=True, on_delete=models.SET_NULL, related_name='+', verbose_name="Page Link" ) panels = [ PageChooserPanel('popular_page') ] The above works fine, but I'm struggling to get the content of the individual pages selected to appear in my templates. {% for popular_page in settings.home.MostPopularPosts.popular_pages.all %} <li> {{ popular_page.title }} </li> {% endfor %} The above loop iterates the expected number of times, but {{ popular_page.title }} doesn't output the page titles. I've tried {{ popular_page.specific.title }} but this also doesn't work. If someone could explain how I should be structuring my template tags to access the individual pages data within my for loop here I'd be eternally grateful. -
Why i can choose only decimal multiple 0,5 in admin panel?
I created a model in Django with multiple choice of numbers from 0 to 14 with steps 0,1. I can see them all in the admin panel, but can choose only numbers multiple 0,5. My model: class SoilPh(models.Model): SOIL_PH_CHOICES = ( (i / 10, str(i / 10)) for i in range(MAX_PH_LEVEL * 10 + 1) ) name = models.DecimalField( max_digits=2, decimal_places=1, validators=[ MinValueValidator(0, '0'), MaxValueValidator(MAX_PH_LEVEL, f'{MAX_PH_LEVEL}') ], choices=SOIL_PH_CHOICES, unique=True, null=True, ) class Deciduous(Plant): soil_ph = models.ManyToManyField( SoilPh, related_name='soil_ph', ) Error: Select a valid choice. 0.3 is not one of the available choices.

how to override _default manager used by ModelSerializer
Given below snippet, class CustomManager(models.Manager): def create(**kwargs): super().create(external_id='xyz', **kwargs) class Person(models.Model): internal_id = models.AutoField(db_column='id', primary_key=True) f_name=models.CharField(db_column='f_name', max_length=15, blank=True, null=True) external_id = models.CharField(db_column='ext_id', null=True, blank=True, max_length=20) objects = models.Manager() custom = CustomManager() class PersonSerializer(serializer.ModelSerializer): class Meta: model=Person fields='__all__' Here, when .save() method gets called on the serializer, the default manager used by the the create function in serializer is objects. I would like this to be changed to custom so that when save call happens, create function inside CustomManager gets invoked. I can achieve this by overriding the super class method create in the serializer. But is there any better workaround for this without overriding base class method? -
Can I use only one redis connection for my django app?
Introduction: django 3.2.16 django-redis 4.12.1 Problem: I use redis as a cache storage. I put the data to redis manually using the next code: from django_redis import get_redis_connection def redis_handler() -> None: redis = get_redis_connection() ... # some business logic ... redis.close() I call redis_handler() often and every time a new connection to redis created. Idea/Solution: Can I create a "global" redis connection once for a project and then import and use it everywhere? Where I can do it? What problems can be? Because I will not close it while the project works. I was inspired FastApi - it has hooks when the project starts and stops. -

Django Oscar - Override form - AddToBasketForm
Alright, To be able to add another field to the "AddToBasketForm" in Django Oscar, I created a fork for the basket app and tried overriding the default "AddToBasketForm". #forms.py import datetime from django import forms from oscar.apps.basket.forms import AddToBasketForm as CoreAddToBasketForm # noqa isort:skip class AddToBasketForm(CoreAddToBasketForm): pass def __init__(self, basket, product, *args, **kwargs): # Note, the product passed in here isn't necessarily the product being # added to the basket. For child products, it is the *parent* product # that gets passed to the form. An optional product_id param is passed # to indicate the ID of the child product being added to the basket. self.basket = basket self.parent_product = product super().__init__(*args, **kwargs) # Dynamically build fields if product.is_parent: self._create_parent_product_fields(product) self._create_product_fields(product) # Create an aditional DateField self.fields['date'] = forms.DateField(initial=datetime.date.today) Now by overriding the form, I get an error saying: TypeError at /catalogue/product_1/ __init__() missing 2 required positional arguments: 'basket' and 'product' So by overrriding the form, I lost the initial form data, basket and product. It feels like this isn't the correct way to modify a form within Django Oscar. Anyone any ideas? Best regards, Kevin -
In Django how to convert a single page pdf from html template?

This is the error in question: /Users///.venv/lib/python3.10/site-packages/django/core/management/commands/makemigrations.py:143: RuntimeWarning: Got an error checking a consistent migration history performed for database connection 'default': connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? I've tried restarting everything, the database, application, computer, etc. I've nuked the venv and created a new one, double checked the database settings in settings.py and they are listed below: DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", "NAME": os.getenv("DB_NAME"), "USER": os.getenv("DB_USER"), "PASSWORD": os.getenv("DB_PASSWORD"), "HOST": os.getenv("DB_HOST"), "PORT": os.getenv("DB_PORT"), } } -
Meta descriptions and titles on all html pages
I'm building a website using django and i'm now esploring about SEO and how to make my page visible when i'll publish it. I read that you should put titles and description for your website in all of your html pages that compose your website, however is it really necessary to put a title and a description for an URL that i use for exemple a password reset that you should not search directly from google? I used a block in the django template of my base.html and i was adding manually a title and a description tag for every html i have in this project. The fact is that i don't know what to write in specific URLs used for the website service reason and i would let it blanked. -
