I can't copy content from an html tag into another django template
Good night friends. I'm trying to display the content of a tag in a template, in another template, using the django "extends" method. Works perfectly with when it comes to "normal", "typed" content: this works: {% block part_of_site %} <div id='tag2'>Context</div> {% endblock %} using a variable, you can't copy to another template: {% block part_of_site %} <div id='tag2'>{{ variable }}</div> {% endblock %} -

mod_wsgi on Python 3.10 does not update Django templates without Apache restart
I have been running a Django server on Python 3.8 with Apache and mod_wsgi for some time now, and decided it was time to upgrade to Python 3.10. I installed Python 3.10 on my server, installed the Django and mod_wsgi packages, copied the 3.10 build of mod_wsgi.so to Apache's modules folder, and everything works great ... however, it seems with this build of mod_wsgi, changes to template files do not take effect unless I restart Apache. As an example, I added a random HTML template file to my website, and started the server with some initial text in that template. Running on the Python 3.8, I am able to change the contents of that template (e.g. echo "More Text" >> test_template.html) and upon refreshing my browser the new text will show up. However doing the same test in 3.10, the new text will not show up. I have tried different browser sessions and hard reloading, it is not a caching issue on the client side, and looking at the response sizes in Apache's access log confirms the data being sent to the client changes in 3.8 but not in 3.10. I have stood up a test server to isolate the … -
Need random number generated in html for embedding into iframe
I am using this embed code for a site. The site is a Django site. I apologize if my terms are wrong, I'm not a developer. . Periodically I return to the site and the graph will not display, but the logo from the host site does. I suspect that it's a caching issue. I tried "no-store" but I'm not sure if I pasted it in properly. I want to add a random number generator to the embed code. In my mind that would be similar to a refresh - again, not a programmer. Django strips css and possibly more. Can anyone either solve my problem or write the random number generator to make the "border-width" 1, 2, or 3? Here is my site with the bug. https://www.twelvebridges.com/twelve-bridges-market-report/. I encounter the bug on Chrome on a macbook. Never the first visit and a refresh solves it every time. I tried "no-store" but probably in the wrong place. I tried Classic Cache Killer as a Chrome extension on my site. I added a gif on the site even though I cannot really articulate what I thought that would accomplish. -

Django - FileField - PDF vs octet-stream - AWS S3
I have a model with a file field like so: class Document(models.Model): file = models.FileField(...) Elsewhere in my application, I am trying to download a pdf file from an external url and upload it to the file field: import requests from django.core.files.base import ContentFile ... # get the external file: response = requests.get('<external-url>') # convert to ContentFile: file = ContentFile(response.content, name='document.pdf') # update document: document.file.save('document.pdf', content=file, save=True) However, I have noticed the following behavior: files uploaded via the django-admin portal have the content_type "application/json" files uploaded via the script abobe have the content_type "application/octet-stream" How can I ensure that files uploaded via the script have the "application/json" content_type? Is it possible to set the content_type on the the ContentFile object? This is important for the frontend. Other notes: I am using AWS S3 as my file storage system. Uploading a file from my local file storage via the scirpt (i.e. using with open(...) as file: still uploads a file as "applicaton/octet-stream" -
Recommended Books & Videos for Vue, Javascript, NUXT, Django

Any recommendations? -

django and nextjs shared authentication
I am building a new front end with nextJs for my Django App. I have been splitting the development to keep all the dashboard running on Django, while the rest runs on nextJs. nextJs is running on domain.com the existing django will be running on dashboard.domain.com I have setup all the Rest authentication for NextJs and is working fine. Now what I'm trying to achieve is when you login from domain.com you don't need to authenticate to the dashboard and reuse the same authentication. Django seems to have some cookie authentication and I'm using JTW for NextJS. What would be my options to solve this dilemma? -
Django: How to write a function based view used for URL with parameter
I am learning Django, using function based views, and I am struggling with the following: I have this path in urls.py path('user/<str:username>',views.UserProjectList,name='user-projects') that is supposed to show all the projects of the particular user (client). In order to reach it, username should be parameter of the function based view, however I am struggling how to write such view... I have this: def UserProjectList(request,username): user = User.objects.get(username=username) #THIS IS WRONG and should return id of the user #user = User.objects.filter(username=username) #also wrong tag_list = ProjectTagsSQL.objects.all() #ProjectTagsSQL and ProjectSQL are connected project_list = ProjectSQL.objects.filter(client=user) #ProjectSQL table has column client_id (pk is id in User) and table contains all the projects context = { 'tagy' : tag_list, 'projecty' : project_list } return render(request, 'home_page/user_projects.html', context) #SHOULD THE PARAMETER BE INCLUDED HERE? I tried to inspire with the code from class based view I found on the internets (thats is working for me but i didnt manage to connect it with ProjectTagsSQL as i managed in FBV, but that's a different problem) but i didnt manage class UserProjectListView(ListView): model = ProjectSQL template_name = 'home_page/user_projects.html' context_object_name = 'data' def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) return ProjectSQL.objects.filter(client=user) # original qs qs = super().get_queryset() # filter by … -

Django selecting a record if its Many-to-Many relation contains data
I have these 2 tables class Job(models.Model): name = models.CharField() collaborators = models.ManyToManyField(User, through="Collaborator") created_by = models.ForeignKey(User) class Collaborator(models.Model): job = models.ForeignKey(Job) user = models.ForeignKey(User, related_name="jobs") role = models.CharField() For a user, I want to select all those Jobs where either created_by=user or the user is in collaborators. The following query does not produce correct results Job.objects.filter(Q(created_by=user) | Q(collaborators=user)) Upon looking at the raw query generated by above code I have found out that this is because the query produced by django ORM creates a LEFT OUTER JOIN between Job and Collaborator, so if there are multiple Collaborators for the same Job then it returns multiple rows of the same job. What I have come up with is the following query Job.objects.filter(Q(created_by=user) | Q(pk__in=user.jobs.all().values("job_id"))) My question is, is there a better query than the above that I can use? P.S. I am using django 4.0 -

How to refer to a related object after deleting an object?
As in the title: How to refer to the related object after deleting the object? Simple example: ModelA(models.Model): ...

How do I send a list of items from my UI to my Django Rest Framework API?
my project uses multithreading to work on several tasks simultaneously. I'd like my UI (I'm using Vue.js) to send a list/array of items to my API to work on each individual item task. ex. [{ "1": "item1", "2": "item2", "3": "item3", ...}] (API searches the items to find what commands to use, that's why I used multithreading so I can work on several tasks at once instead of sending each individual item which takes too long) How do I send a list or array of objects to the API? -

Django - How to update a parent model using a child model?
I am sorry that I am not good at English. I have a two models something like this: Models.py class Parent(models.Model): id = models.BigAutoField(primary_key=True) quantity = models.DecimalField(max_digits=3, decimal_places=0, null=True) class Child(models.Model): parent = models.ForeignKey('Parent', related_name="parent_child", on_delete=models.CASCADE) quantity = models.DecimalField(max_digits=3, decimal_places=0, null=True) If the parent quantity is different from the sum of the child quantities, Updates the parent quantity to the sum of the child quantities. I tried to get an object whose parent quantity is different from the sum of the child quantities: parent = Parents.objects.annotate(sum_quantities=Sum('parent_child__quantity')).exclude(quantity=F('sum_quantities')) It works! But I'm having trouble updating this. Is there a good way? Thanks a lot for your help!
