iOS api call to local RESTful Django fails
Hi all first time posting a question. Long time reaping the benefits of other questions so I'd like to preface this with a thank you to everyone who answers questions on here. Onto my question.

How to store html markups in Django's database
Recently I've started to learn Django, I've decided to make a sample blog website. I've made Post model which creates and publish post. But there's a problem, I've no idea how to attach html markups to my Post object's attribute for instance "text". Here is how I've made Post model: from django.db import models from django.utils import timezone class Post(models.Model): author = models.ForeignKey('auth.User') title = models.CharField(max_length=200) introduction = models.TextField() text = models.TextField() created_date = models.DateTimeField( default=timezone.now) published_date = models.DateTimeField( blank=True, null=True) def publish(self): self.published_date = timezone.now() self.save() def __str__(self): return self.title -

How to use django (python) forms with django-rest-auth?
I am trying to build a Django application with RESTful API (django-rest-framework) and I would like to use django-rest-auth plugin. There is a demo app (http://django-rest-auth.readthedocs.io/en/latest/demo.html) but it is pretty ugly. It has a HTML forms hardcoded in templates, instead of Django python forms.

Django back end with a React front end
The idea I've started off building this social media kind of website, which includes the basic social media pages such as a profile, a status feed, searching, events, and so on. Each page is a seperate django template and data is visualized by using variables in the django template engine. But at this point, I want to change these static pages to something more dynamic, using ReactJS. But how? I would like to make the pages dynamic, but it should still be a multi page website with urls like /user/<id>. I came up with the following option: A template for each page. Each page having one bundle. Let Django handle the routes. Create a seperate Django template for each page, just like a normal Django application would do. Use django-webpack-loader to load bundles. Each page has a seperate bundle. Bundles are created by adding multiple entries in webpack.config.js. This can result in a fairly large amount of entry points when we have 40+ different pages. URLs are handled by Django and are accessible by React via a public javascript variable in the template. Example. And other initial data for the page (such as username, avatar, profile information) are also loaded … -
User-uploaded images not saving to media folder in production
I'm building a Django website where users can upload an image via a form that distinguishes them on the site. These are saved in the /grad/media/ folder (where grad is the name of the app). This is the code that accomplishes this: uni_object = University.objects.get(user=request.user) logo = uni_object.logo if request.method == "POST": form = UpdateUniversityForm(request.POST, request.FILES) if form.is_valid(): data = form.cleaned_data request.user.email = data['email'] request.user.save() uni_object.university_name = data['university_name'] uni_object.website = data['website'] if request.FILES and request.FILES['logo'] != '': new_logo = data['logo'] image = Image.open(new_logo) image = image.resize((400,400), Image.ANTIALIAS) thumb_io = StringIO.StringIO() image.save(thumb_io,format='JPEG') new_file_name = str(int(time.time())) thumb_file = InMemoryUploadedFile(thumb_io, None, '{0}.jpg'.format(new_file_name), 'image/jpeg', thumb_io.len, None) uni_object.logo = thumb_file uni_object.save() updated = True logo = uni_object.logo Essentially I need to convert it into a 400x400 square, and then save it. This code will work on localhost, and the file will be saved correctly. However in Heroku with DEBUG=False: The same code will not save the picture in the media folder Not even by saving a pic manually via the admin panel will the pic end up in media folder Even if the photo exists in the media folder, it will not be rendered on the site. The media folder is pushed to Heroku, so … -

How to backup Django database on Heroku into JSON format?
I want to dump my Heroku (PostgreSQL) database into JSON format. I used to do this in a view and return the JSON string as HttpResponse like this: from django.shortcuts import render from myapp1.models import * from myapp2.models import * from django.core import serializers from django.http import HttpResponse, HttpResponseBadRequest, HttpResponseRedirect from django.contrib import auth from django.contrib.auth.models import User from django.db.models import get_app, get_models # deprecated? def print_all_objects_in_app(appname): app = get_app(appname) all_objects=[] for model in get_models(app): all_objects += list(model.objects.all()) JSONSerializer = serializers.get_serializer("json") json_serializer = JSONSerializer() return HttpResponse(json_serializer.serialize(all_objects)) It used to work for me (I just need to copy paste the page content into a JSON file manually which is OK for me). However, apparently get_app and get_models are not working anymore. Another option is to call heroku run python manage.py dumpdata > dump.json but I can't retrieve the newly (and remotely) created file with heroku git:clone -a myapp. So is there any way to make any of these two methods work? Thanks, -
Reverse url in django signal
I'm trying to send an email with my website address from django signal. I found this question: http://stackoverflow.com/a/15521046/2385132 and proceeded as was advised in the accepted answer, but when using that code, I'm getting this error: AttributeError: 'NoneType' object has no attribute 'get_host' Which is coming from the get_current_site in my code: @receiver(post_save, sender=MyModel) def post_obj_save(sender, instance: MyModel, **kwargs): def _get_html(obj: MyModel): return render_to_string('confirmation_email.html', _get_context(obj)) def _get_context(obj: MyModel): current_site = get_current_site(request=None) domain = current_site.domain action = reverse('obj_activation', request=None, format=None, kwargs={}) url = '{protocol}://{domain}/{action}'.format(protocol=PROTOCOL, domain=domain, action=action) return { 'header': _('Thank you for registering with ASDF.'), 'prompt': _('In order to be able to log in into ASDF administrator panel, you have to activate your account using'), 'link_name': _('this link'), 'activation_url': url } send_mail( _('ASDF account activation'), _get_html(instance), EMAIL_FROM, [obj.owner.email], fail_silently=False, ) So the question is: how do I get full url of my view in a signal?

Providing initial values to formset in django admin inline for a custom form
I have a model "Timings" that goes like this. weekday = models.CharField(choices=constants.WEEKDAYS, max_length=10) start_time = models.TimeField() end_time = models.TimeField() lab = models.ForeignKey('Lab') I had to override the form in django admin and display it as inline in Lab form. I created a form for Timings model and excluded all model fields and introduced some form fields. day = forms.CharField(label="Day", required=False) start_session1 = forms.TimeField(label="Session-1 Start", required=False) end_session1 = forms.TimeField(label="Session-1 End", required=False) start_session2 = forms.TimeField(label="Session-2 Start", required=False) end_session2 = forms.TimeField(label="Session-2 End", required=False) My purpose here is to display a table like structure to user in inline. & rows for the 7 days in the week with storing upto 2 sessions per day. I have overridden the form's save method. Now my instances are getting saved in the DB but in edit mode, I need to display the already present instances in the DB according to the same structure of the form. I ran over the concept of formsets but could not figure out how to override the initial values dynamically. Can somebody help? Stuck at this problem for a week. -

Django Avatar Not Creating Resize files
On my test setup my django avatar scripts are working as they should. I.e. when I upload a profile picture it is updated and can be seen throughout the site as expected. I can also amend the picture and it works. When I upload to my main site everything still works. However, if I then change an avatar profile on the live site all it does is copy the file to the root of the username avatar folder but does not create any resized variants or show on the site. For example if you were to goto str8red.com it would show tingeyal on the right without an image (tingeyal is the ONLY user to try to upload the image on the live server). If anyone would like some code or settings just ask, was unsure what you may require, many thanks, Alan. -

Why is Nginx returning zero length response with X-Accel-Redirect?
I'm stumped on this simple problem. I'm using Nginx with Django and I would like to use the X-Accel-Redirect header to serve up files from a protected location. The Django app manages to locate the file and set the Content-Length header along with the X-Accel-Redirect header (I see them both in the response in Chrome), but the actual response is empty and Chrome gives me the net::ERR_CONTENT_LENGTH_MISMATCH error. I see nothing logged in the nginx access.log or error.log files. Here is my nginx config file: server { listen 9000; server_name server_domain_or_IP; sendfile off; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/username/partie_base_tronc; } location /app/ { alias /home/username/partie_web_tronc/; } location ^~ /temp/ { internal; root /home/username/partie_base_tronc; } location / { include proxy_params; proxy_pass http://unix:/home/username/webapp.sock; } } I initially thought it was a naming issue, but if I delete the one line internal in the config, and I type in [site address]/temp/mypdf.pdf in my browser, for example, I can access the file just fine. But if the X-Accel-Redirect header is /temp/mypdf.pdf, then it doesn't work. Any ideas? -
