Django single sign on between different ports
thank you for taking a look at this question. I have 2 separate Django projects and host the two project through nginx as such: http://xxx.xx.x.xxx:8080/ => Django Project A http://xxx.xx.x.xxx:8000/ => Django Project B The 2 projects are integrated in such a way that the projects share the same user table of PostgreSQL. Each of the projects has its own login page but I can use the same login credentials on the both login pages. The thing is, the projects cannot share login sessions(or cookies?) with each other. So I need to sign in on the project A first and sign in on the project B once more(or vice versa) with the same credential. I've heard that I need to use SSO(Single Sign On) to solve this problem but none of solutions below could solve it. django-simple-sso django-cas-provider/consumer MamaCAS Tried to tweak session options on settings.py (e.g. SESSION_COOKIE_DOMAIN) Maybe there could be some lack of my understanding on one of those solutions above but most of the solutions were outdated or not fit for this case. How could I deal with this issue? Have you solved any similar issues? -

Saving on a Model that has foreign and M2M relation
I have 3 models, say, Fruits, Season, and FruitSeason class Fruit(models.Model): fruit_name = models.CharField(max_length=30) class Season(models.Model): season_name = models.CharField(max_length=30) country = models.CharField(max_length=30) class FruitSeason(models.Model): season = models.ForeignKey(Season, on_delete=models.CASCADE) fruit = models.ManyToManyField(Fruit) I have a form that lets me add Season and (multiple)Fruit details class FruitSeasonForm(forms.ModelForm): season_name = forms.CharField(max_length=30) fruit = forms.CharField(widget=forms.TextInput( attrs={'placeholder': 'Add comma separated values'})) class Meta: model = FruitSeason exclude('fruit', 'season') I tried saving the list of fruits as individual records in the Fruit Model as well as season details in Season on Form post. views.py class seasonal_fruit(request): if request.method == 'POST': form = FruitSeasonForm(request.POST) if form.is_valid(): fruit_season_form = form.save(commit=False) season=Season.objects.create(season_name=form.cleaned_data['season_name'], country=form.cleaned_data['country']) fruit_season_form.save_m2m() form.save() form post does not save on both the models. How do I work around with it? Not sure where am I going wrong. Is it the modelling of those 3 models or something else. -
How to annotate a queryset with the difference between today & a DateField using ExpressionWrapper
I'm trying to do an annotation of the queryset based on a DateField as shown. I am using Django version 1.8.12 and MYSQL version 5.6.40. Tried following How to annotate a queryset with number of days since creation, but here its a DateTimeField. The comments below says "Changing it to Value(now.date(), DateField()) - F('creation_date__date'), doesn't work" The Model code is shown below: class Holding(models.Model): trans_date = models.DateField(_("Trans. Date"), null=False) ... And the annotate query that gives the wrong duration is shown below: today = timezone.now().date() testqs = Holding.objects.filter(id=1) myqs = testqs.annotate(duration = ExpressionWrapper( Value(today, DateField()) - F('trans_date'), output_field=DurationField())) And when i try to print, all I get is None for the duration. Difference printed for reference. for i in myqs: print i.duration, '-', today-i.trans_date None - 1224 days, 0:00:00 None - 1206 days, 0:00:00 None - 1144 days, 0:00:00 None - 1051 days, 0:00:00 None - 1045 days, 0:00:00 I expect the duration to be a timedelta values with the difference between today and trans_date and not None. -

Set up a redirect
There is a mixin in the view, where a slash is added to the url. It is necessary that when you open a non-existent page (for example, example.com/index), immediately throw 404, without 301 (so as not to add a slash at the end). Only a check on 404 status comes to mind, if there is one. Like if there is a page, then do not need to add a slash. If there is no such page, then to formally add a slash at the end (without a redirect). And if the status is 200, then okay, and if not, then throw 404. def is_normal_slash_count(url): temp_url = url slash_count = 0 while temp_url.endswith('/'): slash_count += 1 temp_url = temp_url[:-1] return (slash_count == 1, slash_count) def replace_bad_slash(url, slash_count): if slash_count == 2: return url.replace('//', '/') return url.replace('/'*(slash_count-1), '') def normalize_url(url): if len(url) > 1: if not url.endswith('/'): return url + '/' # replace the url like /contacts//// to /contacts/ good_slash, slash_count = is_normal_slash_count(url) if not good_slash: url = replace_bad_slash(url, slash_count) return url def is_bad_url(url): if len(url) > 1: good_slash, slash_count = is_normal_slash_count(url) if not good_slash: return True return False class RedirectMixinView: def dispatch(self, *args, **kwargs): url = self.request.path redirect_setting = RedirectSettings.objects.filter(url_from=url).first() if … -
Passing class to label from forms.py in ChoiceField/MultipleChoiceField
How can I pass a class to label in the field MultipleChoiceField in forms.py to my template. For example, I want my check box to look like this: <div class="custom-control custom-checkbox"> [...] <input type="checkbox" class="custom-control-input" id="customCheck1"> <label class="custom-control-label" for="customCheck1">Option 2</label> [...] </div> So I create a form that looks like this: class Form(forms.Form): field = forms.MultipleChoiceField(choices=MY_OPTION, widget=CheckboxSelectMultiple(attrs={'class': 'custom-control-input', 'label': 'custom-control-label'})) But in my template the form looks like this: <div class="custom-control custom-checkbox"> [...] <input type="checkbox" class="custom-control-input" label="custom-control-label" id="customCheck1"> <label for="customCheck1">Option 2</label> [...] </div> So the label goes to the input field, not the label. How can I add a label to the label field(<label></label>)? Any help will be appreciated. -

ModelForm validation in Django
I'm trying to validate two forms on one page with single submit button. I don't really mind using either forms.Form or forms.ModelForm knowing the difference. However, when I submit the form for validation all data is being discarded and I get This field is required shouting at me from all fields except the timeout field as that one is optional and defaults to 10.

Django: Trying to return sum of objects between two dates, instead returns sum of all objects
I have a Django table containing events, each marked with a timestamp. For testing purposes I put in some future dates (2020), but instead of returning the count of events between the two dates (0), this returns the sum of all of the events since the beginning of the DB (5). The Django request is as follows: queryset = queryset.annotate( value=aggregate_operation( f"{MESSAGEMODEL_ATTRIBUTE_NAME_IN_DEVICEMODEL}__press_count", filter=timestamp_filter ) ).values(DEVICE_REFERENCE_ATTRIBUTE_NAME, "value") I printed all of the variables involved: filter = (OR: ('messages__timestamp__gte', datetime.datetime(2020, 1, 2, 16, 9, 5, tzinfo=<django.utils.timezone.FixedOffset object at 0x7fe619ed0c18>)), ('messages__timestamp__lte', datetime.datetime(2020, 8, 30, 16, 9, 5, tzinfo=<django.utils.timezone.FixedOffset object at 0x7fe619e9bf60>))) value = Sum(F(messages__press_count), filter=(OR: ('messages__timestamp__gte', datetime.datetime(2020, 1, 2, 16, 9, 5, tzinfo=<django.utils.timezone.FixedOffset object at 0x7fe619ed0c18>)), ('messages__timestamp__lte', datetime.datetime(2020, 8, 30, 16, 9, 5, tzinfo=<django.utils.timezone.FixedOffset object at 0x7fe619e9bf60>)))) queryset = <QuerySet [{'name': '001 - CHANTIER1 - LIVRAISONS', 'value': 5}]> Why isn't this request behaving as expected? -

Django field clash with multiple abstract base clases
I am trying to define entity architecture that, if simplified, can be expressed like this: class M(models.Model): field_m = models.CharField(max_length=255) class Meta: abstract = True class A(M): field_a_1 = models.CharField(max_length=255) field_a_2 = models.CharField(max_length=255) class Meta: abstract = True class B(A): class Meta: abstract = True class C(A): class Meta: abstract = True class D(A): class Meta: abstract = True class DD(D): class Meta: abstract = True class X(B, C, DD): pass As you can see, X has some mixins (abstract entitites). Each of the mixin has their own custom logic implemented inside them. But ultimately all of them have 1 common parent- abstract class A. As far as I understand, this should work. And MRO resolution, indeed, works. However, when starting the project I get 2 errors per each field field A (that are inherited in X): X.field_a_1 : (models.E006) The field 'field_a_1 ' clashes with the field 'field_a_1 ' from model 'X'.

Variable form action="/"
There is a web application that collects data from different sites. The form on the home page is presented in the form of two fields where you can choose from several variants of languages and cities.

Salesforce as Idp unable to logout (django + pysaml2)
Related question: SP-initiated Single Logout not working with SalesForce I'm implementing single-sign-on service using Salesforce as identity provider. My app is now working well with single login. My goal is to make logout from my app (service provider) initiate log out in the identity provider (salesforce). For this purpose I send SAML2 request to Salesforce, however, I always get "We are unable to log you out." error. I searched logs of salesforce to find the cause of the error but didn't find any. In my app i use django, to generate saml I use pysaml2 lib. This is my code to generate logout request: req_id, request = saml2_client.create_logout_request( destination,"<entity-id>",name_id=NameID(text=request.user.email, format=NAMEID_FORMAT_TRANSIENT), expire=soon) # request = saml2_client.sign(request) rstate = saml2_client._relay_state(req_id) msg = http_redirect_message(request, destination, rstate) headers = dict(msg['headers']) location = headers['Location'] return HttpResponseRedirect(location) Generated xml: <ns0:LogoutRequest Destination="<logout_endpoint>" ID="<id>" IssueInstant="2019-08-21T06:44:29Z" NotOnOrAfter="2019-08- 21T06:49:29Z" Version="2.0" xmlns:ns0="urn:oasis:names:tc:SAML:2.0:protocol" xmlns:ns1="urn:oasis:names:tc:SAML:2.0:assertion"> <ns1:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid- format:entity">https://localhost:8000/saml2_logout/</ns1:Issuer> <ns1:NameID Format="urn:oasis:names:tc:SAML:2.0:nameid- format:transient">username</ns1:NameID> </ns0:LogoutRequest> I'm not sure if params I pass to create_logout_request are correct, but I couldn't find any guide on what they have to be, currently entityid value is the url of my salesforce identity provider. -
How to grant temporary permissions to user?
In my application I want the user to re-enter their password before being able to complete a sensitive action such as editing their subscription. After successfully re-authenticating the permissions would be time-limited. I can't find django functionality that enables this, but since django seems to do just about everything else I thought it worth asking - can django do this or can it be configured to do this?
