Make UpdateView accept an encrypted pk in urls.py and return a model object for editing after decrypting the pk
I have a simple working class based view inheriting UpdateView. class UpdateModel(UpdateView): model = ModelName fields = ['field_1' , 'field_2' , ] template_name_suffix = '_update_form' success_url = reverse_lazy('home') and the url that maps back to this view url(r'^edit/(?P<pk>[\w-]+)$' , UpdateModel.as_view() , name="update_model"), Now the issue I'm facing is that I usually encrypt the PK value before sending it outside(since they are sensitive). When I receive them back, I decrypt them to get the Model Object. Brief working of encryption process. def pk_encoder(pk): int_pk = int(pk) hashids = Hashids("MySalt") encoded_pk = hashids.encode(pk_id) return encoded_pk ans similarly I use hashids.decode('string') to obtain my Model Object. But in UpdateView there is no provision for this(that I know of). In urls.py it simply accepts the pk id to return the relevant form for updating a model. I understand that I have to override UpdateView or any of it's function in some way but can't figure out how. May I know how to edit this functionality of UpdateView Thanks in advance. -
Django model query's database access mechanism
class parent(models.Model): ap=models.CharField(max_length=10) user=models.CharField(max_length=10) class Meta: unique_together=(("ap","user"),) db_table='parent' class child(models.Model): userkey=models.ForeignKey(parent,on_delete=models.CASCADE,db_column="ap") pn=models.CharField(max_length=10) st=models.CharField(max_length=10,default='Y') def get_ap(self): return self.ap.ap def get_pn(self): return self.pn class Meta: db_table="child" unique_together=(('userkey','pn'),) Let's say i have ap="apkey" then i can access all child model object for "apkey" by following query. child_obj=child.objects.filter(userkey__ap="apkey") This can be also done without using foreign key relation as follows. parent_obj=parent.objects.get(ap="apkey") child_obj=child.objects.filter(userkey=parent_obj) What i have to know is that how many database access is occurred while executing query in both methods. ? In the second, we knows that it access parent table once and then access child table once. Hence actually two sql query occurs. What about the first one? -

uwsgi processes moving to IDLE state after some time
I'm using uwsgi + nginx for a django application and after some time it seems like some of the uwsgi processes moved to IDLE state(top results 0 %CPU, x %Memory for those uwsgi processes) hence the responses from server gets delayed. My initial configuration was:- workers=2 threads=10 enable-threads=true single-interpreter=true master=true max-requests=50000 In this case, 1 uwsgi process gradually moved to IDLE state, So I updated the worker count like workers=4 threads=10 enable-threads=true single-interpreter=true master=true max-requests=25000 after this setting, on first day 1 process moved to IDLE state and on second day 2 uwsgi process moved to IDLE state. How I can solve this? Due to this 1 active uwsgi process, responses from the server gets delayed and it impacting my users -
Trigger a function in a Django model every time its variables change
I'm working on a Django model and I want to trigger a function every time its variables change.

Django annotate count of foreign key's foreign key
I have three main models: Class Client(models.Model): stuff Class Property(models.Model): client = models.ForeignKey(Client) branch = models.ForeignKey(Branch, blank=True, null=True) Class Branch(models.Model): name = models.CharField(max_length=200) My final goal is basically to try and deduce a client's most involved branch based on the properties it is connected to. I'm sure the best way to do this is using Django's aggregate using annotate, but I'm not sure how exactly to do this. I might have to use extra instead. I know I'll need to something like Client.objects.annotate(branch_count=Count('property__branch')), but I need to somehow add filtering for properties attached to each branch. The other way perhaps is to make use of Collections.Counter d = {} for c in Client.objects.all(): c_qs = Client.objects.filter(pk=c.pk) d[c] = Counter(c_qs.values_list('property__branch', flat=True)) This would build a dictionary of counts, then I'll use it to look up the branch with the highest count for any one client. -
DATE_FORMAT mysql django
I'm currently trying to migrate some MySQL logic to Django (and learning about it in the process). So far the "normal" queries I do understand how to make, but I've hit a wall trying to translate this query: SELECT hour, AVG(sessions) FROM ( SELECT DATE_FORMAT(acctstarttime, '%d-%m-%Y') AS date, DATE_FORMAT(acctstarttime, '%H:00') as hour, COUNT(DISTINCT username) AS sessions FROM radacct WHERE calledstationid = 'CLIENT' AND acctstarttime < 'DATE' GROUP BY date, hour) tb1 GROUP BY hour I can't figure this out, specially the "DATE_FORMAT" part, this query is being used basically to find averages of users per hour over a single table. "CLIENT" and "DATE" are just values I add to the query when executing it. As such it returns something like this: Hour --- AVG 00:00 --- 50 01:00 --- 100 02:00 --- 350 . . . 23:00 --- 120 This query works as I need to, although I have to admit maybe it's flawed since I am by no means an SQL expert (more like a newbie).

How can I get the username of the logged-in user in Django views.py

djangotables to djangotables2 checking column ordering

Why am I getting a 404 error when trying to access my website's domain name, yet if I domain name/home it works?
Okay... let's try to explain things clearly. I've used Python Django to create a dynamic webpage/web-app. After completing the website I have published it using DigitalOcean and have successfully attached my purchased domain name to the name server of DigitalOcean. When I access my website, ordinanceservices.com, i get an error 404; however, if I type ordinanceservices.com/home it works as it should and displays the home page. How, by editing the python files, can I have it to where ordinanceservices.com will display the home page as opposed to error 404? I feel like there's something that I am doing that is fundamentally wrong regarding my .urls structure and thus a rewrite/redirect in the nginx config should not be necessary. Here is the specific error: Page not found (404) Request Method: GET Request URL: http://ordinanceservices.com/ Using the URLconf defined in django_project.urls, Django tried these URL patterns, in this order: ^admin/ ^ ^home/ [name='home'] ^ ^contact/ [name='contact'] ^ ^services/ [name='services'] The current URL, , didn't match any of these. I somewhat understand what is happening here though I do not know how to fix this.

How to use lazy_attribute with Faker in Factory Boy
Context: I have a model with two dates, I want to use factory.Faker for both of them but the second date should always be greater that the first one. I tried this: Model excerpt: class Event(models.Model): execution_start_date = models.DateTimeField() execution_end_date = models.DateTimeField() Factory: class EventFactory(factory.DjangoModelFactory): class Meta: model = Event strategy = factory.BUILD_STRATEGY execution_start_date = factory.Faker('date_time_this_year', tzinfo=pytz.utc) @factory.lazy_attribute def execution_end_date(self): return factory.Faker('date_time_between_dates', datetime_start=self.execution_start_date, datetime_end=now(), tzinfo=pytz.utc) But when I try to use the factory from the python shell I got this: In [3]: e = EventFactory() In [4]: e.execution_end_date Out[4]: <factory.faker.Faker at 0x1103f51d0> The only way I managed to make it work was with like this: @factory.lazy_attribute def execution_end_date(self): # return factory.Faker('date_time_between_dates', # datetime_start=self.execution_start_date, # datetime_end=now(), # tzinfo=pytz.utc) faker = factory.Faker._get_faker() return faker.date_time_between_dates(datetime_start=self.execution_start_date, datetime_end=now(), tzinfo=pytz.utc) But I honestly think there is a better way to do it. My dependencies are: Django (1.8.18) factory-boy (2.8.1) Faker (0.7.17) -
Django App with data from Postgres and dataviz in d3.js
This is my first brush with Django. I'm trying to create an app which has a textinput whose value needs to be queried in the Postgres database. The results will be read into a Pandas dataframe and some aggregations are done, and then the result set would be converted into json that feeds a d3 force directed graph. What I did is: Create a model that has the source, target and weight class Graph(models.Model): source = models.CharField(max_length=25) target = models.CharField(max_length=25) weight = models.IntegerField() I viewed many tutorials online but couldn't get a sense of where to write the code to make the psycopg2 calls to fetch results (is it views.py?) and then how to map the aggregated values to the objects in the model above. Please assist with the workflow. Thanks. -
Django Admin: Save and continue editing raising ValueError
I have to submit an image to an AWS S3 bucket for our one of our models and subsequently save its URI as one of the model's fields. My current approach involves overriding the default save_model method within the ModelAdmin. I haven't gotten around to submitting the image yet, as I'm testing the override code alone. Everything is saving just dandy except when creating a new instance and also when the user clicks "Save and continue editing". When the page tries to load again, a ValueError is raised: invalid literal for int() with base 10: 'None' from django trying to load the url ``/lift/organization/None/` instead of the primary key. I assumed it would have something to do with the return value, but upon inspecting the source code it doesn't appear to be the case (I've also tried returning the object and the object's id). My last attempt to solve was using a redirect, which doesn't seem to have any effect. The main problem is that I want to use the Organization's primary key as the association between the Model instance and the image within the S3 bucket so this is only a problem when the user is creating a new …
