How can I build 'location auto-complete' like Facebook in Django?
How can I build 'location auto-complete' like Facebook? Should I send Ajax request everytime the user type a letter? For example, if user type 'atlanta', then how does Facebook check and find 'Atlanta, GA'? And How can I build the exact same thing in Django??? Thank you so much! -
django model manager or django queryset
I was reading django docs and these two classes seemed similar, here is the sample from django docs: class PersonQuerySet(models.QuerySet): def authors(self): return self.filter(role='A') def editors(self): return self.filter(role='E') class PersonManager(models.Manager): def get_queryset(self): return PersonQuerySet(self.model, using=self._db) def authors(self): return self.get_queryset().authors() def editors(self): return self.get_queryset().editors() class Person(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) role = models.CharField(max_length=1, choices=(('A', _('Author')), ('E', _('Editor')))) people = PersonManager() In the sample code as you can see code in PersonQuerySet can be moved to PersonManager (or move manager to query set) - my point is I can merge one to another without any problem) so what is the difference between manager and queryset? do they have different use cases? or should I simply use one of them and ignore existance of the other one? -
Using PyMongo as Django backend
I'm writing an application with django and I want to use mongoDB as my database. I have searched around a lot and found mongoengine and Pymongo as possible choices. I have decided to got with PyMongo for the time being. But the thing is that I am unable to connect my app to mongoDB. I have tried following so far: from pymongo import MongoClient client = MongoClient() db = client['user_central'] But it doesn't work as it should. Something has to be put in the DATABASES django variable and that's where I'm caught up. How can I connect my django app to mongoDB and use mongo as my Django Backend?? Any help would be appreciated. -

Converting image data string (str) back into bytes
inputFile gets the image data from a image file input <input type="file"> and converts the data into a string (str) to be used in sessions. createView converts the image data string back into image data (bytes) so it can be saved. However when trying to convert the image data string back into image data bytes: session_data = request.session.get('img_data') data = base64.b64encode(bytes(session_data, 'utf-8')) data2 = base64.decodestring(data) It changes the original image data, img_data = request.FILES.get('image').read() witch raises an error when trying to save the image to a ImageField: cannot identify image file <django.core.files.temp.TemporaryFile object at 0x0074B110> so my question is how do i convert the image data string session_data = request.session.get('img_data') back into the original image data (bytes) without altering the data. And i know i could have saved the image using one view that would make it a lot simpler, but createView needs to use this image data in multiple places / forms. i tried doing it this way but i could only use the image data in one form. import base64 def inputFile(request): form = InputFile(request.POST or None, request.FILES or None) if form.is_valid(): img_data = request.FILES.get('image').read() request.session['img_data'] = str(img_data) return redirect('picxs:create') def createView(request): session_data = request.session.get('img_data') data = base64.b64encode(bytes(session_data, … -
queryset django for last value of column if another column is equal to a value

How can i edit the content on my django website pages?
I'm a newbie to django and i have worked on a few projects and in all of them i used the django admin interface to manage the content, which obviously is the content from my models.My main concern is how or rather is there a way i can edit the content in areas like the about section or on my home page without changing the actual html on my code? -
Send weekly emails for a limited time after sign up in django
The Goal: Once a user has signed up they start a challenge. Once they've started the challenge I'd like to be able to send users weekly emails for 12 weeks (Or however long the challenge lasts for). Bearing in mind, one user may sign up today and one may sign up in three months time. Each week, the email will be different and be specific to that week. So I don't want the week one email being sent alongside week 2 for 12 weeks. Should I add 12 boolean fields inside the extended User model, then run checks against them and set the value to True once that week gas passed? Assuming this is the case. Would i then need to setup a cron task which runs every week, and compares the users sign up date to todays date and then checks off the week one boolean? Then use the post_save signal to run a check to see which week has been completed and send the 'week one' email? I hope that makes sense and i'm trying to get my head around the logic. I'm comfortable with sending email now. It's trying to put together an automated process as currently … -
Nginx, WSGI, Django - setting up web server

Django authentication override not working
I created a file "authentication.py" at the same level as the "settings.py" file in my django project.

Django queryset grouped by count of values in Postgres JSONField
My model: from django.contrib.postgres.fields import JSONField class Image(models.Model): tags = JSONField(null=False, blank=True, default={}) tags field value can be empty, or something like: [ {"tag": "xxx"}, {"tag": "yyy"}, {"tag": "zzz"} ] The number or dicts may vary (from 0 to N). I need to make a query that counts Images grouped by number of tags. Something like: { "0": "345", "1": "1223", "2": "220", ... "N": "23" } where the key is the number of tags, and the value is the count of Image objects that contains this number of tags. How can i do that? Thank you for your help! -
dj-stripe / djstripe not using my config vars for heroku deployment

Slicing pandas dataframe using Django template tag 'slice'?
I have a pandas dataframe which I passed into Django HTML. I would like to subset the dataframe when printing it out using Django's template filter 'slice'.

How to create a randomly generated user profile within a city boundary in Geodjango?

Manipulate Request data of TastyPie and Django API
I'm writing an application with django-tastypie and following are my models.py and resource.py files.
