Download the file from the server or output an error if there is one
I have something like this Python code: with open('test.bin', 'rb') as file: file_content = file.read() response = HttpResponse(file_content, content_type='application/octet-stream') response['Content-Disposition'] = f'attachment; filename=test.bin' return response There may not be a file, so you should return an error somewhere, but how to do it so that it can be read on Ajax and output to the user. $.ajax({ url: 'test', type: 'GET', headers: { 'X-CSRFToken': getCookie('csrftoken'), }, xhrFields: { 'responseType': 'blob' }, success: function(data, status, xhr) { var contentDisposition = xhr.getResponseHeader('Content-Disposition'); var matches = /filename=([^;]+)/ig.exec(contentDisposition); var fileName = (matches[1] || 'untitled').trim(); var blob = new Blob([data], {type: xhr.getResponseHeader('Content-Type')}); var link = document.createElement('a'); link.href = window.URL.createObjectURL(blob); link.download = fileName; link.click(); }, error: function(xhr, status, error) { }, }); But the fact is that because of the xhrFields field, the data is perceived as a blob, so in xhr.responseText(type string) I get [object Blob] How do I get the file downloaded and the error output in case of an error? -
How to use filter to check if strings stored in a Django array field are a substring of the input string
Here is how my model looks like. class TestModel(models.Model): test_field= ArrayField(models.CharField(max_length=255, null=True, blank=True),default=list) I want to filter objects which have any substring of the input string as an entry in their test_field. Example: Assume a TestModel object1 has the ['good','morning'] stored in its test_field. object2 has ['run','crew']. Input String is 'Good Evening'. The output should return a query set containing object1. -

Cronjob not working in django. The task is not performed automatically at given time
I have a Django application. In that, there is an application. Within the application, I have a function py file calculate_rev and it has a function calculate_weekly.

It runs when I do it in this way python manage.py crontab run 3c46f4f7c6d33456f68f9796cb22ffc3. I have added logging. When I run it manually the log is created. Otherwise, the log is not created.

DJANGO | How to update relation nested without validate each foreign key

Custom "per-tenant" views in Django
I developed a multi-tenant Django app (single DB with single schema and domain-based, eg. https://tenant-xyz.esample.com) and I'd like to be able to customize some views according to the current tenant. For example, /my_app/some_view might include some logic while /my_app/tenant_xyz/some_view might behave in a different way. Of course I could also have /my_app/tenant_abcdef/some_unique_view_for_tenant_abcdef_only. Following Django's urls.py phylosophy, I guess custom views could be enclosed in their own views_tenant_xyz.py and tenant-related URLs would point to custom views files. The simplest intuition was to to dynamcally include tenants' custom views URLs in urls.py (without typing them statically). Given a urls.py fragment: urlpatterns = [ path('', include('my_app.urls')), path('admin/', admin.site.urls), ] I thougth I could include the following code in urls.py: for tenant in Tenant.objects.all(): urlpatterns += [ path(f'custom_views/{tenant.name}/', include(f'myapp.tenants.urls_{tenant.name}', namespace=f'customviews{tenant.name}')), ] and then define custom CVB (or functions) in each myapp.tenants.urls_{tenant.name}.py but I get an "SynchronousOnlyOperation at / You cannot call this from an async context - use a thread or sync_to_async." (I'm running ASGI with Gunicorn + Uvicorn workers). Btw I suppose using ORM inside settings.py is not the best approach. What would you advise me to do? Keep in mind that each tenant.name is a sort of slug. Thanks in advance. -
the error when I click on the link of the read more button to display a post in detail : Server Error TypeError: fetch failed
`Server Error TypeError: fetch failed export const getAllPosts = async () => { const response = await fetch('http://localhost:8000/blog/posts/'); ^ const posts = await response.json(); return posts; };` honestly i don't understand this error Why this error here, when this getAllPosts works well and it is what allows me to display all the posts on the blog page before I click to see in detail. there should be no error at this level at least if I couldn't display all the posts, I will know and understand that this fetch is not working. I don't know if you see where I'm coming from? -

Http 413 Request entity too large error only in Safari browser
I have a Django app being served by Nginx. When I upload an image via AJAX with PATCH method to my app I get that error. The thing is that I don't get that error on Chrome or Firefox. I only get in Safari. Doesn't matter if it's Mac or iPhone. The photo is 3.5mb. On Nginx conf I have client_max_body_size 50M; On Django I have DATA_UPLOAD_MAX_MEMORY_SIZE = 50*1024*1024 When I inspect the request on those 3 browsers i see this: Firefox: content-length 355705 Chrome: content-length 355669 Safari: content-length 4815964 What it could be? Any ideas? I tried to upload an image with 3 different browsers, but I failed in one of them -
How do I create a serializer for this category model without the product field? DRF
I want to create a Apiview for the model category and define an endpoint for only perform a create category fields but Products and Category are related for ForeignKey method.
