NoReverseMatch in Django for username pass to view
I'm working on a basic Django app (just learning, this is my third small project), and I'm trying to add links to allow a list of every post a user has made. I've got the URLS being created OK (domain/posts/username), and I want this to link to a view (that I've already created, and which works when the parameters I want to pass are hard-coded to a single value), passing the positional arguments to the view. However, I'm running aground on the RegEx / Urls part of things. I think this is the relevant info: urls.py: urlpatterns = [ url(r'^create/', views.create, name='create'), url(r'^(?P<pk>[0-9]+)/upvote', views.upvote, name='upvote'), url(r'^(?P<pk>[0-9]+)/downvote' , views.downvote, name='downvote'), url(r'^userposts/(?P<user>[.]+)', views.userposts, name='userposts') views.py def userposts(request,user): posts = models.Post.objects.filter(url__contains=user) return render(request, 'posts/userposts.html', {'posts': posts}) home.html a href="{{ post.url}}">{{ post.title }}</a><br/>{{ post.pub_date_pretty }} by <a href="{% url 'posts:userposts' %}{{post.author.username}}">{{ post.author.username }}</a></td> With the (?P[.]+) part of the last url line removed, the page will render OK, but the links don't work (as there's no user parameter being passed). With the regex present (not only this one, but the many others I've tried), I get a NoReverseMatch error: NoReverseMatch at / Reverse for 'userposts' with no arguments not found. 1 pattern(s) tried: ['posts/userposts/(?P<user>[.]+)'] … -

Django can't find Webpack bundle when using React
I'm getting this error message: "GET /static/bundles/main-0dfd33c549ecc5de3a40.js HTTP/1.1" 404 1721 as I am navigating my web site on my local host. This bundle was made using webpack and DEFINITELY exists in this location. Every time i collectstatic and create a new bundle, my django recognizes that there is a new bundle but still gives me this 404 error saying that it can't GET it... I'm new to this forum and new to programming so I'm not sure if I'm being detailed enough or if there is other information I should include to help troubleshoot this.. Please let me know. Thank you! -
Error loading MySQLdb module: No module named MySQLdb AFTER virutalenv
Ok I have been pouring over this site and google but cannot find the right answer. I should start by mentioning I'm new to this stuff. I had a django project 90 percent done. I am building it in Linux with a virtualenv. For some reason when I was in the project directory I decided to type 'virualenv .'

get_form throws TypeError after upgrading Django to 1.10

How to create Django 1.7 app on Webfaction server
I am on Webfaction creating a new server for a new version of my clients site. the app is Django 1.7, and I am trying to create a new Django app of that version, but Webfaction only gives you options for back to 1.8. I thought that I could just create the Django 1.8 app, and than use pip to change it to 1.7.1, and it appears that it worked because if I go into the python library on my production server, and do a 'pip list' it shows me this. However when I try to run Django manage.py functions like 'makemigrations, or migrate' I'm getting an error, and I'm sure it's because It's still trying to run Django 1.8 Is there some step I'm missing into changing the Django app to a lower version ? I am having trouble finding anything in the Webfaction documentation. -

Modify DRF Request objects for dispatch to other views
Context AWS Elastic Beanstalk Worker tiers can be configured to accept a single AWS SQS queue automatically. Incoming messages on this queue can be routed to a single endpoint which some instance in the worker tier will respond to; they show up to the workers as POST events. The software my workers are running is based on Django/DRF. Goal I want my worker tier instances to be able to handle more than one type of incoming event. Ideally, SQS could be configured to deliver the requests to more than one endpoint, but that appears to be impossible. My implementation class DispatchSerializer(serializers.Serializer): "`to` is the name of the destination endpoint; `payload` is the data I want delivered" to = serializers.CharField( max_length=80, ) payload = serializers.JSONField() @api_view(http_method_names=['POST']) @permission_classes([AllowAny]) def dispatch(request): """ Dispatch a request to a sibling endpoint.

How to convert custom id field to normal integer field?
I am desperately trying to get along with Django migrations, please help! This is what I have: class ReceiptNumber(models.Model): id = models.AutoField(primary_key=True, unique=True) This is what I need: class ReceiptNumber(models.Model): number = models.IntegerField() "number" is supposed to have the data that was in id before. While doing this Django creates the default ID field. This one needs to have the same IDs as before in order to not break relations with other tables. Can you please help? I tried a lot of things to tackle this, but I really don't know how to do it. I need a step by step guide. The logical way would be to just clone the id field, but I don't know how and where to do that. Thank you so much for your help! Already wasted a few days on this ._. -
Django: CSS Background image not working after update
I just upgraded my Django 1.10 (Python 3.5) app to Django 1.11 (Python 3.6). Most things still work, but for some reason my CSS background images are not being rendered anymore (I tried with the old version and it still works there). This is only happening for CSS, it still loads normally when it is a HTML tag. This is the first time there I am dealing with an update for my Django app, so I'm not so sure about what is the right way dealing with those minor issues. I've been trying different approaches for the background image, but none of them worked. Here is my failing code, {% extends 'base.html' %} {% load staticfiles %} {% block style %} <style> #top { /*background: url("{% static 'img/skyscraper.jpg' %}") no-repeat center center fixed;*/ background: url("/static/img/skyscraper.jpg"); /*background: url('{{ STATIC_URL }}img/skyscraper.jpg');*/ background-attachment: scroll; background-size: cover; min-height: 700px; } </style> {% endblock %} -
how to get rows which have max value2 when value1 is equal using django queryset
for example rowid value1 value2 1 1 2 2 1 3 3 2 4 then select (1,1,3) and (3,2,4) because row1 and row2 have the same value1, and value2 of row2 is bigger than value2 of row1 thank you! -

Django - how to run it on a production server?
I am new to Django Project. I have my app moved to my production server and I have it run: $ python manage.py runserver >>> Starting gulp watch >>> gulp watch gulp process on pid 30427 Validating models... 0 errors found May 18, 2017 - 15:57:08 Django version 1.5.12, using settings 'website.settings' Development server is running at http://127.0.0.1:8000/ Quit the server with CONTROL-C. But it is a production server with an IP, eg: 119.237.27.131 So it **can'**t be running at http://127.0.0.1:8000/ Then what should I do so that the app is running on http://119.237.27.131:8000/ instead? Any ideas? Btw, where is 'website.settings'? -
Django with MongoDB id and _id confusion
Please induldge me: I am new to Django and MongoDB. A tool i am using (called cve-search) populates a mongodb collection 'cves' with documents that have both an _id and id key. In my application i want to generate multiple HTML sections that display values from id which i create in a loop like this: {% for cve in cves %} {% include ".../cveEntry.html" with cve=cve only %} {% endfor %} thus for every cve document something like this is generated: <p> {{ cve.id}} </p> For this my approach was to build a model like: class cves(Document): _id = ObjectIdField() id = StringField() But the cve objects only know an id attribute that contains the original _id value: {'_data': {'_id': None, [... key/values ...], 'id': ObjectId('5911a07bf749d6163d041b0c')}, ...} Am i doing something wrong? Is there a way around it to access the id attribute without renaming the database key? Thank you!
