SocketIO client not able to receive events
I've two services: Resource Manager(RM) & Training. RM is a websocket server while Training is the websocket client. I am using python-socketio for both client & server side. I get an HTTP request on RM based on which I've to trigger an event to Training service. I've written a python script for Training Service which accepts socket connections, does some computation and then triggers an event back to RM. This is the code for the Training service: import socketio client_socket = socketio.Client() @client_socket.event def connect(): print('connection established') client_socket.emit('register', 'training') @client_socket.on('train') def start(input_dict): print("Training triggered!") #do some computation client_socket.emit('training_completed', { 'status': False}) client_socket.connect('http://localhost:8000') client_socket.wait() RM is a django application which stores the socket id of the Training service and triggers the event: def start_training(request): # fetch socket id of training service sid = servicename_to_socketid_map.get('training', None) socket_server.emit('train', {'data': training_inp}, room=sid) return JsonResponse({ 'status': 1, 'msg': 'Training started!!' }) I am able to connect to Training service but I try to send an event particularly to Training, I am not able to receive that event. Can you tell me what am I doing incorrectly? P.S. : I've made the required chances to wsgi.py file for using python-socketio with django Thanks -
django allauth custom login with additional check apart from email and password
Here is my Custom login form from Allauth class CustomLoginForm(LoginForm): def __init__(self,*args,**kwargs): super(CustomLoginForm,self).__init__(*args,**kwargs) self.fields['login'].widget.attrs['class'] = 'form-control' self.fields['password'].widget.attrs['class'] = 'form-control' def login(self, *args, **kwargs): return super(CustomLoginForm, self).login(*args, **kwargs) The above works well when I use only Email and Password, and I would like to check another option, for example custom_field is true I saw this reference, https://django-allauth.readthedocs.io/en/latest/forms.html#login-allauth-account-forms-loginform and it says add your processing, but I struck with how to do it..

fabric3 : Intempestive Login for password when trying to run fab command
I am following the Obey the testing goat book and I try to automate some shell command server side using Fabric3 I have an issue concerning thefab deploy:host=yyy@xxx yyy being username xxx being folder name of my domain name Whenever I run this command, I get Login password for 'xxx': and it just never seem to work even though I enter the correct one Here is what I did so far: 1- did ssh-keygen locally and on the server 2- added on local side a file named authorized_keys which contains id_rsa.pub generated on server side 3- did the same operation on server side Basically, both sides have a file named authorized_keys Local side (resp. server side) have authorized_keys which is just a copy of id_rsa.pub generated by the ssh-keygen command on server side (resp. local side) Could anyone review what I did so far and tell me if I DID understand the problem (or not), and what should I do to resolve this issue Thank vm -

django static files with a different path
I'm trying to make the local development work with everything under a /abc. For example, instead of http://localhost:8080 I everything to be at something like http://localhost:8080/abcd I was able to achieve this by updating the url.py with the following: urlpatterns = patterns('', url(r'^abcd/admin/', include(admin.site.urls), name='admin'), url(r'^abcd/search/?$', views.search, name='search'), url(r'^abcd/$', views.index, name='root') ) # Force Django to serve static assets, if this is not the production if settings.PRODUCTION is False: urlpatterns += patterns('', ( r'^abcd/static/(?P<path>.*)$', 'django.views.static.serve', { 'document_root': settings.STATIC_ROOT } )) Now I can view the pages with http://localhost:8080/abcd but the rendering does not show up correctly because of the static files. I need the static files to be served at http://localhost:8080/abcd/static/. Is there a simple way to make it work? I tried doing the above and it doesn't seem to work. I'm super new to django so I don't fully understand how I can achieve what I'm trying to do. Any help from experts would be much appreciated. -

Django Internationalization issue
I have a application in django 2.2 to translate just as below: LANGUAGES = ( ('pt', _('Portuguese')), ('en', _('English')), ('es', _('Spanish')), ) LANGUAGE_CODE = 'en' The translation itself is working on the templates and for the default language (LANGUAGE_CODE). The issue lies on the translation triggering. Since this is for a REST_API, I will not be using cookies or sessions, the translation needs to watch the Accept-Language header. Debuggins the Locale middleware, I can confirm that the correct language is being found, but the translated text are returned always for the default language (LANGUAGE_CODE), ignoring the language found by the middleware. If I replace the LANGUAGE_COD for pt or es, it works just fine. The django docs states that LANGUAGE_CODE was supposed to be the last fallback. Any hints? -

Absolutely positioned element not rendering correctly in child template
I have a form on my listing page (parent template) that consists of a text input field and a submit button. It happens to be styled with a CSS property of position: absolute. When I request the listing page of the app, the form is positioned correctly according to the offset properties (top, right) that have been defined in the style sheet. However, when I request a detail page (child template), the form doesn't render correctly. The text input field disappears and the submit button shifts over to the left edge of the form. That said, the offsets are still positioning the form correctly. I'm trying to understand what is causing the form to not render properly on the child template? # index.html <--- Parent Template {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <link rel="stylesheet" href="{% static 'css/global.css' %}"> </head> <body> <form class="form_style"> {% csrf_token %} {% for field in form %} {{ field }} {% endfor %} <button class="form_button" type="submit">Search</button> </form> {% block content %}{% endblock %} </body> </html> # detail.html <--- Child Template {% extends 'index.html' %} {% block content %} {% for key, value in mineral.items %} {% if key == 'name' %} … -
How to do type ahead search in SQL server database
I am writing back-end API in Django for an Angular front-end application. I am using an SQL-server database and a linked server. In the front-end I want to use type-ahead search for employees. For ex. In front-end if I want to search for employees having names 'Lisha' then while typing the name itself data is fetched from database (linked server). Currently I am using a query like: select * from openquery([LinkedServer], 'select employeeName from "DB"."View" where "employeeName" LIKE "%Lisha%"') The query will search for all the name like 'Lisha' and then return the result set which I am sending to the front-end. But what I want is as soon as user type 'L' the result should start coming and I can send the result to frontend without waiting for the all the name having 'L' query getting completed. The query I am using is very slow as it waits for all the names having 'Lisha' to get finished and then the result set I can send to the front-end. How can I make it faster and how can I use type ahead search? -

Why does the Django-Summernote prevents prepopulated_fields from working?
I noticed Django-Summernote that I was willing to use in Django Admin prevents PostAdmin from working properly. As soon as I try to replace the default content field with the Summernote one, Auto-Slug stops working and most of the posted contents' texts are not shown. I did a quick search and unfortunately, I could not figure out a way to solve this issue. Therefore, I would be glad if you guys tell me what's wrong. This is my admin.py: from django.contrib import admin from .models import Post from django.contrib import admin from django_summernote.admin import SummernoteModelAdmin class PostAdmin(admin.ModelAdmin): list_display = ('title', 'slug', 'status','created_on') list_filter = ("status",) search_fields = ['title', 'content'] prepopulated_fields = {'slug': ('title',)} class PostAdmin(SummernoteModelAdmin): summernote_fields = ('content',) admin.site.register(Post, PostAdmin)
