Use jinja2 with some django apps but not others?
I cannot seem to get Django to use its default Templates engine for the admin app and use Jinja2 everywhere else. It seems that no matter what I do, I can only ever get one of the two to work at any one time. I've tried reordering whether the Jinja or DjangoTemplates block goes first, adding/removing stuff from the DIRS field, and setting APP_DIRS to False. I either break it all (either with a TemplateNotFound or wrong syntax when the wrong backend tries to render) or only get one of the two functioning. I'm using the django-jinja pip package, which lets me leave my templates in the templates folder instead of moving them to a jinja2 directory. TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": [], "APP_DIRS": True, "OPTIONS": { "context_processors": [ "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.auth.context_processors.auth", "django.contrib.messages.context_processors.messages", ], }, }, { "BACKEND": "django_jinja.backend.Jinja2", "DIRS": [os.path.join(BASE_DIR, "templates")], "APP_DIRS": True, "OPTIONS": { "match_extension": ".html", "context_processors": [ "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.auth.context_processors.auth", "django.contrib.messages.context_processors.messages", "django.contrib.auth.context_processors.auth", "django.template.context_processors.i18n", "django.template.context_processors.media", "django.template.context_processors.static", "django.template.context_processors.tz", ], "match_regex": r"^(?!admin/).*", }, }, ]``` (OK, I think I can get rid of a bunch of those processors that I'm pretty sure I'm not using, but that's a separate issue) -

How to post request to my backend server with long string argument by Graphql
I wanna post a request from my website to back-end (django) by GraphQL. Here is my GraphQL request.

One model for multiple raw query
I have multiple raw query. eg => raw query 1 : select field1,field2 from employee raw query 2 : select field3,field4 from employee Of course, the actual query will more complex than this and Now I have to create multiple models for each of raw queries. model1 : field1,field2 model2 : field3,field4 I just want to know can I create one big model like that => bigmodel : field1,field2,field3,field4 and for query 1, It will return field 1 and field 2 with values and field 3 and field 4 with null. for query 2, It will return field 3 and field 4 with values and field 1 and field 2 with null. It's possible? otherwise, I have to create a lot of models for each query. -
Are HStoreFields the only way to store key:value pairs using Django models?
I am looking to track user views of specific objects. e.g. if a user watches a specific video 3x I want to be able to see how many times that user has watched that specific video. One way of doing this would be tracking user history on every page through the use of GenericForeignKeys and ContentTypes but I read in TSoD that it is best to avoid GenericForeignKeys whenever possible - and for good reason. The other way to do this would be to store key:value pairs in the database and increment the value each time a user visits the page. To do this you would use an HStoreField. The issue with this is that it is PostgreSQL specific while I am still on the SQLite db Django starts off with. This isn't much of an issue because I planned to switch to PostgreSQL anyways but the whole scenario has me wondering: is there another way to accomplish this task that I am not seeing in all my research? Much thanks for any input in advance! -
Python functions are called too soon in Django
Even if I assign it to a variable, the API call triggers too soon. I've implemented a few ideas, as shown in the examples (not the actual code, but same principles). """ Example #1 """ fruit = 'banana' def search_engine(fruit): engine = { 'apple': google.search(Time="10 hours ago"), 'banana': yahoo.searchNow(Time="12 min ago"), 'pear': bing.searchNow(Time="13h ago"), } print(engine[fruit]) search_engine(fruit) """ Example #2 """ fruit = 'banana' def search_engine(fruit): GS = google.search(Time="10 hours ago") YS = yahoo.searchNow(Time="12 min ago") BS = bing.searchNow(Time="13h ago") engine = { 'apple': GS, 'banana': YS, 'pear': BS, } print(engine[fruit]) Let's assume that Time is an improper value, and will throw an exception regardless. in Example #1, however, "apple" is called first and throws an exception, when "banana" should be called instead. In Example #2, it throws an exception at "GS = google.search(Time....", instead of doing it for "YS = yahoo.searchNow..." I've only had this issue since trying to integrate my Python project into Django. -
Access-Control-Allow-Origin is set, but I'm still getting CORS Error
I'm trying to connect my a React Application to a Django Server. The React application is running on http://127.0.0.1:3000/ The response headers has Access-Control-Allow-Origin: http://127.0.0.1:3000 set, yet I am still seeing the error. I am currently using Django's corsheaders package as recommended everywhere. Decent example of the recommendation How can I enable CORS on Django REST Framework.

Django - CSS file not linking with template correctly
In my project, I attempt to link my html template to a CSS file that I have in my static folder. I have added STATIC_ROOT, STATIC_URL and STATICFILES_DIRS to my settings.py. In my static folder, I have a folder called styles, and within that, I have a file named signup.css . I have also ran python manage.py collectstatic. In my template I attempt to reference that CSS file to change the colour of my h1, however no change occurs. Template: {% load static %} <head> <link rel="stylesheet" href="{% static 'styles/signup.css' %}"> </head> <h1>YO</h1> <div id="signupformdiv"> <form class="signupform" action="{% url 'signup' %}"> </form> </div> signup.css: h1 { color: red; } The colour of my h1 remains black. Does anybody know the issue? Thank you. -
Queried Results from Database Disappear on Pagination: Django
I am new to using the Django framework. I am creating a form to take in User input to query a database. I want to display the queried results on the same page, below the from fields.

Django/Bootstrap 4: How to align elements inside of multiple parent divs

How to serve protected video file on Django production?? Nginx help needed
I need a serve a protected video file on production in a super quick easy way, but it's not working. No models are required. I only need to upload ONE video, have it display on a django template page, and that's it. So no true password with salting / hashing is required (which I know how). With my current setup the video serves fine from static, but not as a protected file because it's easy to copy/paste from the source html. Every article I've checked only shows how to download a specific file as a forced download, but I need some clarity on what's happening... This and this are the best articles I've found. Everything else is either wrong, or not as complete as those. Problems: On production I'm getting a 404 not found error when setting the header for response['X-Accel-Redirect'] = '/protected_files/' in the view, And a 403 forbidden error when setting the response['X-Accel-Redirect'] = protected_url in the view. What's happening?? I think the problem is with my location /protected_videos/ {...} directive, but I don't know why. Maybe it's my secret_page/ url???

Django how to serialize multiple file upload with validation using forms.ModelForm?

Can I filter objects in forms.ManyToManyField to equal value selected in another field?
I want to set a queryset on a ManyToManyField to get all objects that have a ForeignKey equal to ForeignKey set in another formfield. class ProductAdminForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(ProductAdminForm, self).__init__(*args, **kwargs) self.fields['variants'].queryset = Variant.objects.filter(variantCategory__productCategory__name_single='test') This works, It selects all "Variant"'s where value of "name_single" of productCategory in its variantCategory is equal to 'test'. I want to replace 'test' to be equal to "name_equal" of productCategory set in this very form. Here is some code to ilustrate how the objects relate to eachother. class Variant(models.Model): variantCategory = models.ForeignKey('VariantCategory') class VariantCategory(models.Model): productCategory = models.ForeignKey('ProductCategory') class ProductCategory(models.Model): name_single = models.CharField() https://imgur.com/a/OLah8at This shows the field that should define the productCategory to equal to. I realize this is kind of hard to explain, if any of you need extra code/info let me know! Also, I just need the query to get all objects where productCategory equals to another productCategory. The "name_equal" part doesn't really matter, could be the id of the object to! -
