Consistent user authorization across url with/without www
I need to clarify a fundamental concept (beginner here). In a Django web app I'm practicing on, I notice that if one logs in via going to example.com, they remain logged out on www.example.com (and can then go on to create a clone account). 1) Why does this happen? 2) What's the standard practice to iron out this issue? I.e., give one consistent experience across www and no-www. In case the answer is as basic as just a redirection, I could use some pointers and an illustrative example there too - I'm using nginx reverse proxy with gunicorn. -
Why do I get AttributeError when trying to open a folder in django cms filer manager?
I have a fresh install of django cms and when I try to create a folder and add images to it using the filer app it just gives me the error: AttributeError at /en/admin/filer/folder/1/list/ 'str' object has no attribute '_meta' it looks like the issue is in filer/admin/folderadmin.py in directory_listing I thought maybe it had something to do with the fact that I was using django-storage to store on s3, but I took that part out so that it just stored the files locally and I am still getting the error. If anyone has any information on how to fix this please let me know. This is happening out of the box with no previous data. -

Django functional testing database results after calling view
I'm writing functional tests for my Django views using django.test.Client to simulate HTTP requests (this is much faster than using LiveServerTestCase + Selenium, and I am only testing my Django views in these tests, not the associated JavaScript code). I have a view that bulk-creates a number of objects all at once and I want to verify that the correct number of objects was, in fact, created. Testing by hand reveals no issues; the objects do get created and the result is correct. However, objects created by a view POSTed to by django.test.Client don't show up in querysets that are created after the view is called, even though they do show up in subsequent calls to entirely different views. How do I get querysets in tests to notice changes in the test db caused by requests issued from django.test.Client? -

Beginner to Intermediate projects in Python
Can anyone add me to their projects so I could gain some much needed Python coding experience? It could be an Open Source Project or even Closed Source projects. It would be nice to have a project where I could actively engage in with people with greater experience who could answer my questions and point me in the right direction. I like challenges so, the more obscure the project for me the better. Cheers. -

The included urlconf module does not appear to have any patterns in it
I have this code for my urls.py inside the blog file, which is accessed easily by the urls.py in the mysite folder. from django.conf.urls import url, include from blog import views from django.views.generic import ListView from blog.models import Post urlpatters = [ url(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/(?P<post>[-\w]+)/$', views.post_detail, name='post_detail'), url(r'^$', ListView.as_view(queryset=Post.objects.all().order_by("date"),template_name="blog/base.html")), ] When I try to access the /blog/ file, which should lead to the blog/base.html file, it gives the following error: The included urlconf module 'blog.urls' from '/mysite/blog/urls.py' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. Any help would be highly appreciated! -

Django template not getting view data
Im trying to make my own app called Services, I have been following the Django tutorial on how to make your own app. I am making this app in Django CMS, I essentially want this app to contain templates that I can then insert into pages of the CMS via the includes tag. I have made my models, views, urls and template. But the template isn't receiving any data from the view. I am able to create new service objects in the backend so I know my model is working how I want and I'm not getting a template error when including it. Here are my models, views, URL file and template. I suspect it is either something to do with how I setup my view or how I'm pulling my view in the URLs file. Currently the only output I get in the template is "No Services Available" which it is set to output when there is no service_list from the view. models.py from django.db import models from djangocms_text_ckeditor.fields import HTMLField import filer.fields.image from django_extensions.db.fields import AutoSlugField from colorfield.fields import ColorField class Service(models.Model): title = models.CharField(max_length=200,default="") slug = AutoSlugField(max_length=50, populate_from='title') color = ColorField(default='#FFFFFF') tab_content = HTMLField(blank=True,help_text='Describe the service you … -

Posting data to django rest framework using javascript fetch
I'm trying to post data to my django rest framework using javascript fetch. I've already set up and liked the DRF to my model and got everything set up from the backend. I used the postman app to ensure "get", "post" etc are all working as interned. However, now I'm having problem posting data using javascript to post the data using fetch. I want to add data to my article model which has a "headline", "tag", "content", "background_image" and the user that posted the article. This is how my code looks like data = JSON.stringify({ headline: "Testing", tag: "Testing", background_image: "Testing", content: "Testing", user: 1 }) fetch( "http://127.0.0.1:8000/api/v1/articlesapi/", { method: "post", headers: {"Authorization":"Token ed73db9bf18f3c3067be926d5ab64cec9bcb9c5e"}, body: data } ).then(function(response) { return response.json(); }).then(function(data) { console.log("Data is ok", data); }).catch(function(ex) { console.log("parsing failed", ex); }) However, I keep getting the error parsing failed TypeError: Failed to fetch.
