Django form: can't access help_text from Django template
Using Django 1.10. From the docs, it seems that I should be able to access help_text from the template but I can't. class StudentForm(ModelForm): class Meta: model = Student fields = ['name', 'age'] help_text = { 'age': "enter your age in years and months", } In the template, the following prints nothing: {%for field in form %} {% if field.help_text %} <p class="help">Here{{ field.help_text|safe }}</p> {% endif %} {% endfor %} -
Append json data and refresh django template automatically
I receive json files to my django website when some asyncronous tasks are finished with celery. When I get this json files I append this information to the database with a function in a view (every time I refresh the page). And I also show an HTML table with this data. I want to append json data automatically when it is available (without refreshing the page) and I also want to refresh the HTML table automatically (without refreshing the page). Any Ideas?? Thanks, -

Despite specifying the IAM role, Docker container can not access the Cloud watch log
First, I use the server environment: sever: django + nginx + uwsgi cloud: docker + AWS ECS logging: AWS CloudWatch log service + watchtower third party app I want to connect the credentials to the docker container. Because the watchtower needs permission to access the clooud watch log. So I applied the IAM Role to the task definitions in the same way as the http://www.tothenew.com/blog/attach-iam-role-to-an-aws-elastic-container-service-task/ link. The role of IAM was set as follows. AmazonEC2ContainerServiceFullAccess CloudWatchLogsFullAccess However, If I command curl 169.254.170.2$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI, server returns 404 page not found error. And when I connect to the application, 502 error occurs. Do you know why? -
requirejs + django_select2
I've to tell that I'm not a JS expert, and I've none arround me :( I've already adapted some scripts, but I'm a pretty old school dev :) I'm building a wagtail / django app using requirejs as js assets combiner.

How to create users in Django's backend database when using Vue.js and Auth0 for frontend authentication
I am trying to use Vue.js as a frontend, and Django as the backend for an SPA. In the frontend, I am leveraging Auth0 for user authentication and I want to send the id_token obtained from user registration/creation from Auth0 to the backend to create specific user profiles in real-time. Previously, I was using the following code to enable profile creation once a user is created: # Whenever a User account is created, it creates a profile for it too. def create_profile(sender, **kwargs): user = kwargs["instance"] if kwargs["created"]: user_profile = UserProfile(user=user) user_profile.save() post_save.connect(create_profile, sender=User) def __str__(self): return self.user.username I am fairly new to Vue.js and Javascript. Although Vue.js is a breeze to use, but I can't seem to figure out how to replicate similar functionality in Vue.js with Auth0. Any help/guidance/pointers in the right direction are appreciated. Thanks. -

Redirecting to new Django url after successful Ajax function execution?
I have one ajax function, which is doing request to check whether user input username is valid or not. For that i wrote one ajax function and created one view to check the validity. The view check the validity and return a JSON response. $.ajax({ url: 'some/url', data : {'username' : 'username'}, dataType: 'json', success: function (data) { if (data.results == "faile"){alert('Username not available')} }, complete : function(){ location.href = "some/new/url" + with json_data } }) }; If the username is taken, it ask the user to input again and if it's available, a new page will be loaded, and the datatype from the server will be a JSON data with multiple values. How can i load the new page with JSON data as a parameter. I used location.href but how can i put json as a parameter? -
Django how to implement a unread notification count system?
I am using django-channels (websocket) to create a chat room system. When user is on room-list page, he would see a badge beside the room name which shows number of new notifs since he entered room last time (a user can be a member of multiple rooms). Also if a new notification comes when user is still on room-list page, the corresponding bage should +1. So my question is, do I need to make new tables for this or it can be done with session+websocket. I have a message table already. -

Create A Sentiment Analysis Web App [on hold]
I'm building a web app that will scrap data from Twitter api and news webites, analyse sentiments for the keyword chosed by the "client" then output the results ( For now I just want to output a number between 0 and 1 ) Each user should be able to save their keywords. I know it's a lot of work but I just start learning and I'm tryin to figure it out wich tools should I use and do no waste time learning useless stuff. Here's what I have so far: Windows 7 32bit / 4 Gb Ram Python 3.6 + Pycharm Community Text Analysis API (Indico.io) Shared Hosting + cPanel (?!) Twitter API Heroku Account + CLI PostgreSQL 9.6 Git 2.8 Python Libraries: Pip - SetupTools - VirtualEnv - Tweepi I have no idea wich framework should I use to build the front end ( Django/Flask/etc..) and also how to build the app locally then deploy to heroku. Actually, I just know how to request an API call and output the result on the console so please be kind. Thanks! -

Django - Heroku - committing a change

I cloned the app using heroku git:clone -a myapp I changed the base.html file. I literally removed a few lines of HTML. I then ran git add . git commit -m "Some helpful message" git push heroku master And I get this error traceback: Counting objects: 6, done. Delta compression using up to 4 threads.

send_mail not working in django

Thank you for your message.') In success(request), I added a bit of redundant code to try sending mail in a different way just to check if other method is working or not. None of it is working. Can anyone please tell me why? I am a bit confused. Password is correct and i allowed less secured apps for gmail.This program is not throwing any error. Success page is called if email(request) tells that it has sent mail successfully. I am using django 1.11 and Python 2.7 Thankyou in advance :) -
