How to submit a mock url? (Django)
I have a problem, I can't test my forms by using requests. add_playlist = self.client.post(reverse('new-playlist'), data={'url': 'https://dailyiptvlist.com/dl/it-m3uplaylist-2018-03-11-1.m3u'}) I need to create a mock response for 'https://dailyiptvlist.com/dl/fr-m3uplaylist-2018-03-06.m3u' so it will be acceptable to test adding a channel while the url isn't maintained. So, I need to create a mock response for this url. I can't imagine how to do this. Please help me. -

Django: Multiple values in Radio Select Form
I've got a radio select form that displays addresses that the user has saved. Currently, when the user visits the "select address" template, they are only shown the 'street' field for each address that they've saved. This is controlled by the "return self.address" line below as I've established through testing. I'd like user to see the street, city, and state of each of the addresses that he/she has saved. From the list, they'll select the radio button next to the address that they'd like to ship to. models.py class Order(models.Model): user = models.ForeignKey(UserCheckout, null=True, on_delete=models.CASCADE) billing_address = models.ForeignKey(UserAddress, related_name='billing_address', null=True, on_delete=models.CASCADE) order_id = models.CharField(max_length=20, null=True, blank=True) class UserAddress(models.Model): street = models.CharField(max_length=120, null=True, blank=True) city = models.CharField(max_length=120) state = models.CharField(max_length=120, choices=STATE_CHOICES, null=True, blank=True) def __str__(self): return self.address I'm using a class based view. Here are some functions within that view that I belive are controlling the output within the template: def get_addresses(self, *args, **kwargs): user_check_id = self.request.session.get("user_checkout_id") user_checkout = UserCheckout.objects.get(id=user_check_id) b_address = UserAddress.objects.filter(user=user_checkout) return b_address def get_form(self, *args, **kwargs): form = super(AddressSelectFormView, self).get_form(*args, **kwargs) b_address = self.get_addresses() form.fields["billing_address"].queryset = b_address return form Within the template, I've got the following: {% csrf_token %} {{ form }} <input type='submit' value='Select' /> </form> I … -
Serializing nested object in Django Rest Framework

How do you call a user defined function in views.py DJANGO
The requirement is to display the logged in username and his role in the organization in all the pages at the top right corner. The role can be identified by the permissions he is given. My approach: I thought of creating a user-defined function in views.py and call it in each and every other function. The function that I create should check the current user's permissions and based on them his role should be decided. All these details must be sent to base.html so that it will render and display the username and his role every time the page is loaded. Any suggestions on other approaches are welcomed and if my approach is entirely wrong please let me know. -
Django Session Data lost after clearing browser Data
Im using django 1.11.7 and the session objects to store data from users that are login works fine but when I clear the browser data the session object is lost, as far as I know if you use this 'django.contrib.sessions', you're setup to save the session object in the DB and im able to see Data in the Db each time someone logs in but the problem is that for some reason I cant use this data when i fetch it maybe is the way I fetch the data because the data is being saved in the DB here is how I fetch the data in the views: this is the normal way that works until I clear the browser data in_test = request.session['in_test'] then in some reading they suggest that even if the data is being saved in the db some cookies are created to match that data and they use this to some how also get the data from the session obj but same result: in_test = request.session.get('in_test') but at least there is a hint that the browser cookie is obviously missing since I cleared but the question is how to pair or directly fetch the session object … -

How to override Django admin `change_list.html` to provide formatting on the go
In Django admin, if I want to display a list of Iron and their respective formatted weights, I would have to do this. class IronAdmin(admin.ModelAdmin): model = Iron fields = ('weight_formatted',) def weight_formatted(self, object): return '{0:.2f} Kg'.format(object.weight) weight_formatted.short_description = 'Weight' I.e: 500.00 Kg The problem with this however is that I would have to write a method for every field that I want to format, making it redundant when I have 10 or more objects to format. Is there a method that I could override to "catch" these values and specify formatting before they get rendered onto the html? I.e. instead of having to write a method for each Admin class, I could just write the following and have it be formatted. class IronAdmin(admin.ModelAdmin): model = Iron fields = ('weight__kg',) def overriden_method(field): if field.name.contains('__kg'): field.value = '{0:.2f} Kg'.format(field.value) I.e: 500.00 Kg -

Django admin, changelist_view, ModelAdmin seems to act like a singleton
I noticed a strange behaviour while extending ModelAdmin. I have this code: class MakeModelAdmin(admin.ModelAdmin): ... def changelist_view(self, request, extra_context=None): if request.user.is_superuser: self.list_display = ['company', 'name'] # else: # self.list_display = ['name'] return super().changelist_view(request, extra_context=extra_context,) The goal is to change list_display dynamically based on user (supervisor or not). I log in with two different users, in two different browsers, one of them results to be a superuser, the other isn't. self.list_display is set by one of users but debugging the request with the other user I can see the variable still set, so it changes the next behavior of the other user's view. Uncommenting the lines it works but I don't like it at all. It seems to me it's acting like a singleton. I also tried to change to: super(MakeModelAdmin, self).changelist_view(request, extra_context=extra_context,) But it has the same effect. Is there any solution for that? Maybe this is not the right way to achieve my goal? -
(CSRF token missing or incorrect.) using AJAX in Django

How to display uploaded file to user
I have a django view function that allows the user to upload a file. After the upload completes, the user just needs to be shown a file on a page. If I save the file, I can find it the media cdn I've set up and can view it using the link generated in the table in django admin, but what I'm trying to do is return the image that the user uploaded as a response back to them to view it. Here is the code I have for the view: def home(request): title = "Upload your photo" form = PhotoUploaderForm(request.POST or None, request.FILES or None) if request.method == "POST": print request.POST if form.is_valid(): instance = form.save(commit=False) instance.save() name = "" for filename, file in request.FILES.iteritems(): name = request.FILES[filename] imageFileName = name imageUrl = imageFileName if form != None: return HttpResponseRedirect(imageUrl) context = { "title" : title, "form" : form } return render(request, "home.html",context) Right now, when the image is uploaded, the user is just redirected to a url with the filename concatenated to the original url but the image isn't displaying. How can I redirect the user to a page with the image they just uploaded? -
