How to load chart in Django Template
I have an Altair chart which I want to render in a Django Template. The chart is converted into a json object in the views. Here is the code views.py def home(request): if request.method=='POST': year = request.POST['year'] df, cus_dict = generate_df(year) bar_obj = barGraphAltair(year, df) bar_obj = json.loads(bar_obj.to_json()) print(bar_obj) context = {'bar': bar_obj} return render(request, 'index.html', context=context) return render(request, 'index.html') template <div id='altair-viz'> {% if bar %} {{ bar|safe }} {% endif %} </div> This just prints the json in the template. I know I have to use Vega to render the graph but I am not sure how to do that in jinja syntax A temp solution One way I got this to work, is by creating a different view and calling that view in the template as follows views.py def renderAltair(request): df, cus_dict = generate_df('2017') bar_obj = barGraphAltair('2017', df) bar_obj = json.loads(bar_obj.to_json()) return JsonResponse(bar_obj) template <script> vegaEmbed('#altair-viz', "{% url 'altair' %}") </script> This works, but as you can see from the original code, I get the year by submitting a form and passing that to the function for generating the graph. So I need the graph to be created in the home view -
How to change the language based on user choice?
I translated my site using Rosetta. I have two languages; en and tr. I created a language field in my UserProfile model, and I created a button in navigation bar for changing user's language choice. What I want is; User's language choice will be the language of the website. For example; When user click the TR button, re_path turns http://127.0.0.1:8000/tr/ or user click EN button re_path turns http://127.0.0.1:8000/en/ in every page. How can I do that? urls.py urlpatterns += i18n_patterns( re_path('', include('customer.urls')), re_path('', include('register.urls')), re_path('', include('approvals.urls')), ) models.py class UserProfile(AbstractUser, UserMixin): username = models.CharField(max_length=500, unique=True) first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) ... language = models.CharField(max_length=250) -

Could not find the GDAL library in django. What can I do to resolve this problem?
I am working in django project and need to use PointField imported from django.contrib.gis.db.models. To use it, I installed GDAL by brew install gdal. When I enter gdal-config --version in terminal after installing it, I got the message 3.3.1. I believe this tells GDAL has been successfully installed. I also updated the database setting in settings.py like this. DATABASES = { 'default': { "ENGINE": "django.contrib.gis.db.backends.mysql", 'NAME': config("DB_PROD_NAME"), 'USER': config("DB_USER"), "PASSWORD": config("DB_PASSWORD"), "HOST": config("DB_HOST"), "PORT": config("DB_PORT") }, } And this is the models.py where PointField is used. from django.contrib.gis.db import models class Address(models.Model): address_name = models.CharField(max_length=100) address_name_detail = models.CharField(max_length=100) address_type = models.CharField(max_length=11) address_coord = models.PointField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: managed = False db_table = 'address' The problem is when I try python3 manage.py runserver or import the model Address in views.py, I get an error django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal", "GDAL", "gdal3.2.0", "gdal3.1.0", "gdal3.0.0", "gdal2.4.0", "gdal2.3.0", "gdal2.2.0", "gdal2.1.0", "gdal2.0.0").

How is django's default root homepage rendered?
This is a kind of want-to-know itch. Many questions here ask how to replace the default Django homepage (e.g. ). I understand that issue. What I'm curious to know is how the default page is rendered when a new project is created (i.e., in debug mode). Even though my question is not as directly practical as knowing how to replace the default homepage, I have the feeling that if I figure it out, I may understand how Django works a bit better. I would expect it to be in the default urls.py file, but the only entry by default in urlpatterns of urls.py is path('admin/', admin.site.urls). My first naive expectation would be an entry in urlpatterns that you could remove or comment out. Since there's nothing there besides admin/, I'm guessing there's some other built-in app or middleware that specifies the default homepage, but I don't know where to look. Here's my progress in understanding this so far: Commenting out DEBUG=True in settings.py causes the default homepage to no longer appear. I've seen this documentation about how Django processes requests, which mentions middleware that can set the urlconf attribute on a request that changes the default, ROOT_URLCONF. So far Django … -
Passing Dropdown Choice to Modal Using Django For Loop
I have a dropdown with choices. The dropdown should be linked to a modal where I'd like to say "You selected Choice A" (or B or C), depending on what was clicked.

How to replicate "Available Groups" to "Chosen Group" functionality in Django Admin
I am moving from Rails to Django and trying to convert a Hamper Business website I run. Love Django!! I have hampers with a number of products. Each hamper has different products. I'd love to be able to use the following structure to move products into a hamper. An example: Django uses the following to have a list of groups which then moves to Chosen Groups: All I seem to be able to get with a ManyToManyField is a list box which I have to select by control and clicking to add multiple fields. This becomes impractical and not easy to read. To take it one step further, I'd love to be able to include a product more than once. For example, a hamper which has three bottles of the same beer. I would like to not have to set up three seperate products for the same hamper. Thanks so much in advance for pointing me in the right direction. -
Celery tasks get blocked by SSE client
I am running a SSE consumer in order to update a few tables like this @app.task(ignore_result=True) @worker_ready.connect def xx_sse_nodes_uptime_info_consumer(sender, **kwargs): update_tables... By some reason, other tasks are not triggered when we have a .delay calling other tasks. If I remove the task above, other tasks will work normally. Also, when CELERY_TASK_ALWAYS_EAGER=True and CELERY_TASK_EAGER_PROPAGATES=True everything runs fine. Since the SSE consumer uses stream=True the xx_sse_nodes_uptime_info_consumer never ends. I am not sure why this blocks others tasks tho as there are enough threads. -
