Django ElasticSearch DSL DRF aggregations
What is the correct approach to adding aggregations to Django ElasticSearch DSL DRF? The codebase contains some empty filter backends https://github.com/barseghyanartur/django-elasticsearch-dsl-drf/tree/a2be5842e36a102ad66988f5c74dec984c31c89b/src/django_elasticsearch_dsl_drf/filter_backends/aggregations Should I create a custom backend or is there a way to add them directly to my viewset? In particular, I want to calculate the sum of an IntegerField across all results in a particular facet. -
Merge duplicate dictionaries in a list
I have this list of dictionary and I am trying to merge the duplicate dictionaries in the list below is the sample of the list of duplicate dictionary [ { "userName": "Kevin", "status": "Disabled", "notificationType": "Sms and Email", "escalationLevel": "High", "dateCreated": "2019-11-08T12:19:05.373Z" }, { "userName": "Kevin", "status": "Active", "notificationType": "Sms and Email", "escalationLevel": "Low", "dateCreated": "2019-11-08T12:19:05.554Z" }, { "userName": "Kevin", "status": "Active", "notificationType": "Sms", "escalationLevel": "Medium", "dateCreated": "2019-11-08T12:19:05.719Z" }, { "userName": "Ercy", "status": "Active", "notificationType": "Sms", "escalationLevel": "Low", "dateCreated": "2019-11-11T11:43:24.529Z" }, { "userName": "Ercy", "status": "Active", "notificationType": "Email", "escalationLevel": "Medium", "dateCreated": "2019-11-11T11:43:24.674Z" }, { "userName": "Samuel", "status": "Active", "notificationType": "Sms", "escalationLevel": "Low", "dateCreated": "2019-12-04T11:10:09.307Z" }, { "userName": "Samuel", "status": "Active", "notificationType": "Sms", "escalationLevel": "High", "dateCreated": "2019-12-05T09:12:16.778Z" } ] I want to merge the the duplicate dictionaries keeping the value of duplicate keys and have something like this [ { "userName": "Kevin", "status": ["Disabled","Active", "Active"] "notificationType": ["Sms and Email", "Sms and Email", "Sms"] "escalationLevel": ["High", "Low", "Medium"] "dateCreated": "2019-11-08T12:19:05.373Z" }, { "userName": "Kevin", "status": "Active", "notificationType": "Sms and Email", "escalationLevel": "Low", "dateCreated": "2019-11-08T12:19:05.554Z" }, { "userName": "Samuel", "status": ["Active", "Active"], "notificationType": ["Sms", "Sms"], "escalationLevel": ["Low", "High"], "dateCreated": "2019-12-04T11:10:09.307Z" }, ] anyone with a simpler way of achieving this please share your … -

django-rest-auth "Unable to log in with provided credentials."
If I create a user in django admin and login with that user's correct credentials I fail to have access I do not know why that is. But one more thing, I create user in postman and login it works fine and in django admin it does not work. I think the problem with that, it may be hashing the password because if I type password as user12345 in admin it appear as user12345 but if I do this process in postman it hashes the password like pbkdf2_sha256$150000$W4T5vHbtbI3o$bV+CLOohqcmd0Gi70jcEyRTbOyp45LU5PhBwWHbdCnU= for hashing the password I have this class UserManager(BaseUserManager): use_in_migrations = True def _create_user(self, email, password, **extra_fields): user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user def create_user(self, email, password=None, **extra_fields): extra_fields.setdefault('is_staff', False) extra_fields.setdefault('is_superuser', False) return self._create_user(email, password, **extra_fields) def create_superuser(self, email, password, **extra_fields): extra_fields.setdefault('is_staff', True) extra_fields.setdefault('is_superuser', True) if extra_fields.get('is_staff') is not True: raise ValueError('Superuser must have is_staff=True.') if extra_fields.get('is_superuser') is not True: raise ValueError('Superuser must have is_superuser=True.') return self._create_user(email, password, **extra_fields) set_password should hashes passwords and I think it may be problem for not logging in my opinion. Any idea please for this issue? Thanks -

switch user in django
I have django server installed under ownership of user say 'X'. Now I want to switch to user 'Y' and execute some scripts. Currently for changing user I am using sudo su "Y" -c "commands to execute" . I have added user "X" in sudoers file so that now it does not ask for a password. Is there any way to do it without sudo.I have already tried it by editing /etc/pam.d/su file so that it does not ask for password when user X runs "su Y" without sudo. Is there any other way in which this can be achieved? -

Heroku Django requests static files that don't exist
Using whitenoise for managing production static files. Django==2.1.4 whitenoise==4.1.2 My production server is requesting static files that look like mine (ie bootstrap.min.js) but have characters on the end (ie. bootstrap.min.xyz789). I notice that in my STATIC_ROOT directory there are already a bunch of these (ie. bootstrap.min.abc123) but they don't match the ones that my heroku site is requesting (ie. bootstrap.min.xyz789). I ran collectstatic both locally and in heroku but no luck. What are these files and why don't they match? PS - no issue locally only in heroku. -

ReactJS not displaying Django REST Framework API data
I am trying to use ReactJS to build a simple website that pulls data from my Django REST Framework API. The issue I am running into, is that my data is not being output by React. I am certain that my Django backend is running flawlessly. I get no errors when running it, and can view my API data via "http://127.0.0.1:8000/api/". Here is my frontend ReactJS code: import React, { Component } from 'react'; class App extends Component { state = { usernames : [] }; async componentDidMount() { try { const res = await fetch('http://127.0.0.1:8000/api/'); const usernames = await res.json(); this.setState({ usernames }); } catch (e) { console.log(e); } } render() { return( <div> {this.state.usernames.map(item => ( <div key={item.id}> <h1>{item.username}</h1> </div> ))} </div> ); } } export default App I have tried updated my CORS_ORIGIN_WHITELIST via settings.py and includes all variations of localhost.

403 from Jquery in Django
Yes, I have learned that it has to do with the csrf stuff, yet none of the copypaste I have found around has worked. (example below) The second question I ask myself is that I dont seen how from the jquery code can you actually connect to a function in a view by just indicating the url of the page. there are a lot of functions in the views.py file. How does it know to which it has to go? Just because you write extra code in the view function? It will have to go and check all functions? So here is the jquery: I get a 403 when clicking on the radio button to send the word. $(document).ready(function(){ $('input[type="radio"]').click(function(){ var valor = $(this).val(); data: "{'csrfmiddlewaretoken': '{{csrf_token}}' }", $.post('/', JSON.stringify({valor:valor}), function(data){ }); }); }); -
