Edit password of user in admin panel
I've overwrite "save_model" method to manage user's password in my admin's panel application.

Django on Nginx connection refused
I want to run my django app on nginx webserver + gunicorn. I have setup most of the stuff already following tutorials and got to the point where I need to setup Nginx. I have my app in: /home/ec2-user/davidbien That's also where my virtualenv is installed. Inside davidbien folder I have the below script guni.sh: #!/bin/bash set -e LOGFILE=/home/ec2-user/davidbien/logs/guni.log LOGDIR=$(dirname $LOGFILE) NUM_WORKERS=3 # user/group to run as USER=ec2-user GROUP=ec2-user ADDRESS=0.0.0.0:8000 cd /home/ec2-user/davidbien source /home/ec2-user/virtual/bin/activate test -d $LOGDIR || mkdir -p $LOGDIR exec gunicorn_django -w $NUM_WORKERS --bind=$ADDRESS \ --user=$USER --group=$GROUP --log-level=debug \ --log-file=$LOGFILE 2>>$LOGFILE This seems to be running fine as I don't get anything when running it. I can also run the app using gunicorn davidbien.wsgi:application --bind 0.0.0.0:8000 This works fine. Now, I get to nginx setup.

To use Turbolinks 5 with Django, how can I automate the inclusion of Turbolinks-Location when using redirect()?
According to the Turbolinks 5 documentation for "Following Redirects" (https://github.com/turbolinks/turbolinks#following-redirects): When you visit location /one and the server redirects you to location /two, you expect the browser’s address bar to display the redirected URL. However, Turbolinks makes requests using XMLHttpRequest, which transparently follows redirects. There’s no way for Turbolinks to tell whether a request resulted in a redirect without additional cooperation from the server. And the solution for this is to: send the Turbolinks-Location header in response to a visit that was redirected, and Turbolinks will replace the browser’s topmost history entry with the value you provide. The Turbolinks Rails engine performs this optimization automatically for non-GET XHR requests that redirect with the redirect_to helper. I have a great interest in using Turbolinks on my Django (1.11) project and I'm wondering if anyone could point me in the right direction of how to create a new Django redirect() function or modify the existing one to always include the Turbolinks-Location header that is needed for redirects to function as expected. I definitely do not want to be manually setting this header every time I do a redirect. There is a similar entry in the 'Redirecting After a Form Submission' section (https://github.com/turbolinks/turbolinks#redirecting-after-a-form-submission) … -
Using Django and Ajax to dynamically update information not working
When I have a many-to-many field that I want to change dynamically (ie, from the view to update the database without refreshing the entire page), such as when a user clicks a 'Follow' button for an object (as many different users can follow many different objects) then Ajax will make the request and the database will be updated. However, this Ajax call does not seem to work for dynamically changing a boolean property (changing something to True or False) for any given object. This class-based view works to dynamically add or remove a user: if user.userprofile in obj.followers.all(): following = False obj.followers.remove(user.userprofile) else: following = True obj.followers.add(user.userprofile) updated = True However, this code does not work to change an attribute to True or False: if user.is_authenticated(): if user.userprofile.content_pref == True: display = False user.userprofile.content_pref = False else: display = True user.userprofile.content_pref = True updated = True How might I achieve this effect? Through clicking on a button, I want a user to toggle their model object attribute from False to True or vice-versa...Thanks -
Getting related objects via tags in Django
My goal is to build a "Recommended Products" section in my e-commerce website when accessing an individual product page. I have a sereis of products which have several user-defined tags in the admin. The tagging system is a combination of django-taggit and modelcluster, as detailed in the Wagtail-CMS docs. I am trying to make it so that when a product page is accessed, Django looks at all other products with the same/similar tags and lists them in the "Recommended Products" section, based on the number of identical tags. The django-taggit docs seem to address this need in their API with the get_related() function, as per their docs. I am struggling to get this working however as I keep on encountering errors, the latest being Exception Type: KeyError at /categories/test-category/test-product/ Exception Value: (15,). Here's my code so far: class ProductTag(TaggedItemBase): content_object = ParentalKey('Product', related_name='tagged_items') class Product(Page): ... tags = ClusterTaggableManager(through=ProductTag, blank=True) def get_context(self, request): context = super(Product, self).get_context(request) current_tags = self.tags related_products = Product.objects.filter(current_tags.similar_objects()) context['related_products'] = related_products return context -
Extending the Django 1.11 User Model
I am attempting to work out how to extend the Django user model to add information to a user. I can't seem to get it to work. What am I doing wrong? Is it okay to have foreignkeys within the same model I am extending in to? How do you create a superuser, or do you have to do it manually through the python manage.py shell? Here's my code so far: class PersonModel(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) firstName = models.CharField(max_length=50) lastName = models.CharField(max_length=50) company = models.ForeignKey(CompanyModel, on_delete=models.CASCADE, null=True) phone = models.ForeignKey(PhoneModel, on_delete=models.CASCADE, null=True) email = models.EmailField(blank=True) def __str__(self): return '%s %s - %s - %s, %s' % (self.firstName, self.lastName, self.company, self.phone, self.email ) class Meta: ordering = ['firstName'] verbose_name = "Customer Contact Information" #verbose_name_plural = "Contacts" @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: PersonModel.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() -
From JWT - ImportError: cannot import name 'InvalidTokenError'

How to serve static img in separate js module in django project
There is a notifications module in JS+JQuery which is duplicated on every page. I want to bring all duplicated to one single js source file. The only problem is that there are using some static files like that, using append function: {% static "img/man.svg" %} And while JS code is in the file with html, it's rendered by django, but if we bring the logic to separate js file, it won't render. How to solve this problem? -

Whitenoise giving errors on jquery-ui.css when doing collectstatic
I'm trying to install the jquery-ui-dist package, and when I run collectstatic, whitenoise seems to have trouble when a url is inside quotations in a stylesheet. The error I get is: MissingFileError: The file 'jquery-ui-dist/"images/ui-icons_555555_256x240.png"' could not be found with <whitenoise.storage.CompressedManifestStaticFilesStorage object at 0x7fb16b7000b8>. The CSS file 'jquery-ui-dist/jquery-ui.css' references a file which could not be found: jquery-ui-dist/"images/ui-icons_555555_256x240.png" Please check the URL references in this CSS file, particularly any relative paths which might be pointing to the wrong location. I see that it seems to think it's looking for a bad filename, as it keeps the quotations around it, and I assumed that the reason was because the source file has url("images/ui-icons_555555_256x240.png") when the quotations are unnecessary, so I ran sed -i 's/\"images\/ui-icons_555555_256x240.png\"/images\/ui-icons_555555_256x240.png/g' jquery-ui.css on the source file, which removed the quotation marks, but I still get the error. I'm assuming there is a problem with either whitenoise or the jquery-ui-dist package, but until the problem is fixed on their end, I at least need a temporary solution, and I'm not even sure where the actual problem lies. -

python how to create errors manually and handle network errors
I'm using the requests library (within a django app) to consume an api. (eg to validate some data, payment details, address details etc....) However I'm working with an api that doesn't use http status codes (eg if it is a failed response I don't get a http 500 but a 200 instead and the details that it failed are in the response. It also uses custom internal status codes.). I've created a handler to handle the exceptions for the various endpoints I need to interact in this api. However I'm not clear on a couple of things: 1) how to manually create an error and log it (with traceback etc..) and raise it when the api (eg below when status returns false), how can I include the full traceback and the status, status_code, message, and data? Is it best to pass these into the custom error and raise this. (not sure how to get traceback too)? 2) What's the best way to test the below code, (ie that I get the right error raised, when api is down, returns 500, or doesn't return a json response, or if a json response but returns status as false etc...?
