distribution of application on the cloud (not SaaS)
I want to distribute my software with cloud account . Ideally I want cloud provider to sell the app for me and to handle the transaction. Currently I work with Heroku and Heroku does not provide such an option. What are my options with other providers(ideally similar to Heroku)? -

Django validated_data type hint
I am studying type hints and would like to follow because it can help me troubleshoot the bug during development. If validated_data is single type of key and value for example mydict = { "age": 123 } def read_mydict(mydict: typing.dict[str, int]): # do something Question: (Pdb) validated_data {'type': 2, 'file': <InMemoryUploadedFile: cmoc_import_file.xlsx (application/vnd.openxmlformats-officedocument.spreadsheetml.sheet)>, 'description': 'Test again validated_data'} Then I have to write function to read that validated_data. def add_d_records(validated_data: Dict[?,?]): """ Take validated_data and put it to UserProfile :param validated_data: :return: """ import pdb; pdb.set_trace() How to write the type hint? Or I have to write my own class to handle this? -
Django + SSL + mysql: TypeError: __init__() got an unexpected keyword argument 'server_hostname'

Django Integrity Error when adding post in a form that excludes a foreign key
the cause of the error is simple. The admin site asks me to select or browse user when I am logged in. So, I excluded the field to hide it in the admin form. It generates the integrity error. How do I tell django to attach the currently logged in user (in the admin area) as the creator of the object? I have seen a few posts that require me to make use of forms.py but I want to use the default admin template. Where do I make the edits at least? -
Check if user is online and notify to the connected user in Django
I am writing a chat module for my project using Django and stomp protocol (with ActiveMQ). When a user logs in, his connected user will be able to chat with him. This is the model to represent the connection class Connection(AppModel): connection_host = models.ForeignKey(Member, related_name="connection_host") connector = models.ForeignKey(Member, related_name="connector") accepted = models.BooleanField(default=False) def __unicode__(self): return "%s - %s" % (self.original_member.nickname, self.target_member.nickname) I can actually know who are online when the page is refreshed, thank to this; however, I don't know how to auto-publish those information to the page through the ActiveMQ. For example, when a user in the chatbox, he posts something and then on the server, it will send the message to the broker to broadcast back to the other end. However, when the user is online, there is no event in order to trigger the message. The only solution I can think of is making a Celery periodic task every 10 seconds to broadcast back to the all the online users their online connections; however, this is a bit tedious. Is there any better way to do so ? -

Return dictionary from AJAX call using Django
I am making an AJAX call and would like it to return a dictionary of objects. No matter how I try to return the data, it throws an exception.

For loop to create Scatter chart with CanvasJs using Django data as input
I found that I can create nice scatter plot with CanvasJS into my HTML templates (see the link: http://canvasjs.com/docs/charts/chart-types/html5-scatter-chart/) I am creating a website using Django and a MySQL database. In one of my tables (models) I have 3 fields VARCHAR containing different values: - the 1st field contains values for X axis. - The 2nd field contains values for Y axis. - The 3rd field contains one letter labels. Here is an example for one entry if it is not clear: 1st field: 999.99;-89.01;-60.29;-145.83;-140.76;-148.24;-88.70;56.92;69.08;-121.37 2nd field: 143.12;146.51;143.73;177.58;121.68;116.45;-14.05;20.77;15.82;168.20 3rd field: CPPEEECTTE As you can see, values are separated by ";" in fields 1 and 2. there are 10 values in field 1, 10 values in field 2, and 10 corresponding letter labels. All fields are 1 long string. So my question is simple, I don't know how to make a for loop in javascript so that those coordinates will be taken in the scatter chart. Here is the example of the canvasjs for scatter chart I want to obtain: <!DOCTYPE HTML> <html> <head> <script type="text/javascript"> window.onload = function () { var chart = new CanvasJS.Chart("chartContainer", { title:{ text: "Title of my scatter chart" }, data: [ { type: "scatter", dataPoints: … -

Passing additional login params to custom django auth backend

How to send data from form to pdf template using Django easy_pdf

How can I import template tags provided in an external package into a Django tag library?
I have a module thirdparty_lib.contrib.django.tags.foo - which is not part of a Django app - that contains about this code: from django import template register = template.Library() @register.filter def transform(obj, arg): pass I'd like to use the filters and tags from it in an actual Django app and tried this naive approach in mydjangoapp/templatetags/foo.py: from thirdparty_lib.contrib.django.tags.foo import * However this yields a TemplateSyntaxError, stating that foo isn't a registered tag library. The app does work when the contents of the prior are copy-pasted in bulk into the latter. -
python django models request.user
I am trying to implement a model that automatically filters data based on the user. I was able to modify the user model and add a value for "company" that references a table of companies. I have a table that has a company value as well (call it data_table). Ideally when ANY user logs into the system, the data filtered to match company value on user to company value on data_table. So far I have it working, but I want to overwrite the get_query method to incorporate what I have and I can't figure out how to get the current logged in user into the model without passing it from the view. I would think that in the below I could just use in models.py: current_user = request.user cid = current_user.company.id The advantage being I don't have to remember to put the filter in when I use the model. The error that gets thrown is: Exception Value: global name 'request' is not defined Here is what works: models.py: from __future__ import unicode_literals from django.db import models from django.contrib.auth.models import AbstractUser class Company(models.Model): name = models.CharField(max_length=40, blank=True) def __str__(self): return self.name class User(AbstractUser): company = models.ForeignKey(Company, on_delete=models.CASCADE, default=1) class data_tableManager(models.Manager): def … -

Django RAW SQL, named parameters
I have a complex query, with some inner joins, a little where clause and HAVING clause too, this is for a report. In this case, I can't use Model.objects.raw, so instead, I'm using cursor.execute(sql). My question is with my parameters. I have 20 parameters and some of them are repeated (company_id in every inner join). Using a dict and %(key)s don't work here when using cursor.execute, it only works with Model.object.raw. How can I name parameter, to just pass it once? Or is there a method to sanitize my entire query, avoiding SQL injection? Pass all the 20 parameters and repeating them in order in a list is not readable. -

showing micro µ symbol in a python django template
I have some data I am working with i.e displaying it using django on a template. So, the data (NOT from a db) looks like so: <td>{{obj.var1}}</td> and this displays: 1.54 \xb5 The \xb5 here is for the micro symbol. To display the micro symbol, I wrote a little template tag, which looks like so: .... def search_replace_filter(query): return query.replace("\\xb5",r'''&micro;''') ... and this stupidly now displays: 1.54 &micro; .. which is not what I want...
