Permission error with pymemcached and Django 2.2
I am updating a project to Django 2.2.3 from 2.1 and having issue (permission error) when I change from the python-memcached to the pymemcached binding. I can still use python-memcached which works but is deprecated in 2.2. My Memcached setting are (from Ansible): memcached_socket_perms: 775 memcached_socket_file: /run/memcached/memcached.sock memcached_memory_cap: 128 memcached_dependencies: - memcached memcached_user: memcache The asgi server runs under www-data under Ubuntu 20.04. I am using the Django cache setting from the Django docs (here for pymemcached): CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache', 'LOCATION': 'unix:/run/memcached/memcached.sock', } } -
A sequential scan rather than index scan
I can't figure out why this query is exceptionally slow on my production database. I see two sequential scans - the first is from a filter on the dockets_table.content_type_id = 2 and the second one I can't even figure out what it's related to. This query takes many minutes on production machine and needs to be like a few seconds max. The query: SELECT DISTINCT ON (rank, "dockets_document"."id") "dockets_document"."id", "dockets_document"."title", "dockets_document"."url", "dockets_document"."content", "dockets_document"."num_tables", "dockets_document"."num_pages", "dockets_document"."tables_processed", "dockets_document"."summary", "dockets_document"."importance", "dockets_document"."title_vector", "dockets_document"."search_vector", "dockets_document"."datetime_created", "dockets_document"."datetime_modified", "dockets_document"."docket_id", "dockets_document"."docket_number", "dockets_document"."date_filed", "dockets_document"."pdf", ((1 * ts_rank("dockets_document"."search_vector", plainto_tsquery('public.bb'::regconfig, 'rendering set'))) + (0.8 * ts_rank("dockets_attachment"."search_vector", plainto_tsquery('public.bb'::regconfig, 'rendering set')))) AS "rank", ts_headline("dockets_document"."title", plainto_tsquery('public.bb'::regconfig, 'rendering set'), 'StartSel=''<mark>'', StopSel=''</mark>'', HighlightAll=true') AS "title_snippet", ts_headline(CONCAT(array_to_string("dockets_document"."content", ' ', ''), CONCAT(array_to_string("dockets_attachment"."content", ' ', ''), array_to_string(T4."content", ' ', ''))), plainto_tsquery('public.bb'::regconfig, 'rendering set'), 'StartSel=''<mark>'', StopSel=''</mark>'', MaxFragments=5') AS "content_snippet" FROM "dockets_document" LEFT OUTER JOIN "dockets_attachment" ON ("dockets_document"."id" = "dockets_attachment"."main_document_id") LEFT OUTER JOIN "dockets_table" ON ("dockets_document"."id" = "dockets_table"."object_id" AND ("dockets_table"."content_type_id" = 2)) LEFT OUTER JOIN "dockets_table" T4 ON ("dockets_attachment"."id" = T4."object_id" AND (T4."content_type_id" = 8)) WHERE ("dockets_document"."search_vector" @@ plainto_tsquery('public.bb'::regconfig, 'rendering set') OR "dockets_attachment"."search_vector" @@ plainto_tsquery('public.bb'::regconfig, 'rendering set') OR "dockets_table"."search_vector" @@ plainto_tsquery('public.bb'::regconfig, 'rendering set') OR T4."search_vector" @@ plainto_tsquery('public.bb'::regconfig, 'rendering set')) ORDER BY "rank" DESC, "dockets_document"."id" ASC LIMIT 8 Explain Analyze output: Limit … -

Keeping a file contents between page loads with Django
I am trying to create a page that reads information from a CSV file and then allows a user to run tests against the information in that CSV file. All of this is done on just a single page. This is my page layout: [Upload Form] [Upload Button] [Test Drop Down Selection Menu] [Data Input Text Area] [Parse Button] [Results] So basically you would upload a file. Then it would reload the page and populate the Test Drop down Selection Menu. Then you would select the test, paste the data in the text area and then click parse. Then it will display results underneath the Parse Button. Then I would like for the drop menu to still remain populated with tests so that the user can continue to just run tests and not have to continue uploaded the CSV file. This is my views.py function for this single page. def parse(request): form = CSVParseForm() if request.method == 'POST': if (request.FILES): csvfile = request.FILES.get('csv_file') reader = csv.reader(codecs.iterdecode(csvfile, 'utf-8')) tests = [] for row in reader: tests.append(row[3]) return render(request, 'cbsa/csvparse.html', {'form':form, 'tests' : tests}) else: # Read info from the session to know what to parse input_data = request.POST.get('cbstextarea') else: pass return … -

Import local settings if a command line argument is defined
I have the following code at the end of my Django settings: if not TESTING: # Don't use local settings for tests, so that tests are always reproducible. try: from .local_settings import * except ImportError: pass local_settings.py contains all the external dependencies URLs used by my Django application, such as database server URL, email server URL and external APIs URLs. Currently the only external dependency my test suite uses is the local database; everything else is mocked. However, now I'd like to add some tests that validate responses from the external APIs I use, so that I can detect quickly when an API change and the API owner does not notify me beforehand. I'd like to add a --external-deps command line argument to "./manage.py test" and only run tests that depend on external APIs if this flag is enabled. I know that I can process arguments passed to that command by overriding the add_arguments() method of the DiscoverRunner class, as described in Django manage.py : Is it possible to pass command line argument (for unit testing) , but my conditional Django settings loading are run before that, so the following won't work: if not TESTING or TEST_EXTERNAL_DEPS: # Don't use … -

Multiple field inheritance from Group excludes database fields in Django

django reverse lookup using strings
I want to know is it possible to do reverse lookup between two tables without using foreign key in form of id. Means instead of matching between the two tables using a field id, can i make it using field values containing strings. example- if in both the tables i have column with different names but containing almost similar values in form of string. Is it then possible to reverse lookup other fields on behalf of these common string fields? table 1: SKILLS PROFILE python, R ml engineer python, java se table 2: NAME CandidateSKILLS Ajay Kumar python, java Suman python In this case is it possible to do reverse lookup using the skills and candidate skills columns if they contain almost similar string inside it. -

How to Model Authenticated User Metadata in Django
I'm using Django (Django Rest Framework) and I'd like to design an API that outputs songs as JSON when the user is not authenticated and additional (meta data) fields when authenticated. Non authenticated: GET: /songs/{song_id} ... class Song(models.Model): created_at = models.DateTimeField(auto_now_add=True) composed_year = models.PositiveIntegerField( blank=True, null=True) title = models.CharField(max_length=50) lyrics = models.TextField(max_length=10000) artist = models.ForeignKey(Artist, on_delete=models.CASCADE) genre = models.ForeignKey(Genre, on_delete=models.CASCADE) key = models.CharField(blank=True, null=True, max_length=2) Authenticated: GET: /songs/{song_id}/{user_id}/ This endpoint would return all the original song data PLUS an additional key field for the authenticated user and an arbitrary number of fields (e.g. notes). How would I model this? I would need a table mapping user ID to song ID plus additional fields. Is this what a through table is for? This doesn't seem like a many to many...rather one-to-one: one song has one user preference (per user), and one user preference has only one song... -

My models are: class Post(ModelBase): title = models.CharField('Title', max_length=255) description = models.TextField() finished = models.BooleanField(default=False) author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='post_author') likes = models.ManyToManyField(User, through='PostLike',) tags = models.ManyToManyField(Tag, related_name='tags') def total_likes(self): return self.likes.count() class PostLike(ModelBase): post = models.ForeignKey(Post, on_delete=models.CASCADE) user = models.ForeignKey(User, on_delete=models.CASCADE) I have this, but it does not work for me correctly. Instead of telling the Likes of the users' post, count the Likes that each user has given. users = User.objects.annotate(likes_count=Count('postlike', Q(post__is_active=True)))\ .order_by('likes_count').reverse()[0:5] -
Show only link to file which exists Django Python
I have a four FileFields in my models.py like 2 below: file_1 = models.FileField(blank=True, upload_to='PN_datoteke/%Y/%m/%d/', verbose_name="Datoteka 1") file_2 = models.FileField(blank=True, upload_to='PN_datoteke/%Y/%m/%d/', verbose_name="Datoteka 2") Each time different number of files is uploaded and some are left empty. I use following in my .html page to offer a download option of the file which is uploaded: <p class="article-content mb-1"><strong>Datoteka 1: </strong><a href="{{post.file_1.url}}" download>Preuzmi</a></p> <p class="article-content mb-1"><strong>Datoteka 2: </strong><a href="{{post.file_2.url}}" download>Preuzmi</a></p> Problem is, I have 4 upload options and if some are not used I get following error: The 'file_2' attribute has no file associated with it How can I suppress the empty fields (.destroy, .remove) before they are generated on the page, if file doesn't exist? I guess I must use a javascript? How to check and not display a if a file doesn't exist? -
