Custom Authentication Login in Django via email
I am trying to understand login methods in Django. So because I want to login with email not username. I wrote a custom authentication backend and exposed it in settings.py AUTHENTICATION_BACKENDS = ( 'accounts.backend.EmailAuthenticationBackend', 'django.contrib.auth.backends.ModelBackend', ) class EmailAuthenticationBackend(ModelBackend): def authenticate(self, request, email=None, password=None, **kwargs): try: user = Account.objects.get(email=email) if user.check_password(password): return user except user.DoesNotExist: pass And in view user_login how I authenticate the user. And it's actually works. I mean kind of... def user_login(request): nxt = request.GET.get("next") form = UserLoginForm(request.POST or None) if form.is_valid(): email = form.cleaned_data.get("email") password = form.cleaned_data.get("password") user = authenticate(email=email, password=password) login(request, user) if next: return redirect(next) return redirect("/") context = { "form": form } return render(request, "accounts/user_login.html", context) the authenticate() method is returns the user. But redirect() is not working because in browser thinks user not logged in. I am not sure about how to handle the session part. and custom UserLoginForm class UserLoginForm(forms.Form): email = forms.CharField() password = forms.CharField() def clean(self, *args, **kwargs): email = self.cleaned_data.get("email") password = self.cleaned_data.get("password") if email and password: user = authenticate(email=email, password=password) if not user: raise forms.ValidationError("user not exist") if not user.check_password(password): raise forms.ValidationError("incorrect password") return super(UserLoginForm, self).clean(*args, **kwargs) The second issue is if email or password wrong. it doesn't … -

Highlight new posts in django/react
I have Post model in django which has Channel as foreign key. What I want to do is , whenever there is a new post in post model, that channel should get highlighted and that should be user specific. What I am thinking is whenever new post is created, there will be one flag is_highlighted which will be set to true. Is this the right way to do? any other better way? TIA class Post(models.Model): user = models.ForeignKey( User, on_delete=models.DO_NOTHING, blank=True, null=True, related_name="post_user_id") channel = models.ForeignKey( Channel, on_delete=models.DO_NOTHING, blank=False, null=False, related_name="post_channel_id") and channel model is class Channel(models.Model): channel_name = models.CharField( max_length=250, help_text="Channel channel_name") -

Update View - Page not found
I am attempting to create an update view for a build log(subpost). My URL structure is /post/pk/buildlog/pkz/update The error I am getting is Page not found Raised by: blog.views.UpdateBuildLog ... post/<int:pk>/build-log/<int:pkz>/update/ [name='build-log-update'] The current path, post/118/build-log/53/update/, matched the last one. view class UpdateBuildLog(UpdateView): model = BuildLog form_class = BuildLogupdateForm template = 'blog/buildlog_update.html' url path('post/<int:pk>/build-log/<int:pkz>/update/', UpdateBuildLog.as_view(), name='build-log-update') I believe the error is being caused because of the two primary keys not being passed into the view but I cant figure out how to pass the second primary key(pkz) into the view -
How to maintain user session across different devices and browsers from the access code email link in django
After validating the user, I'm sending out the access token to user's email along with the link to come back to the same page. [![Access Token email][1]][1] [1]: https://i.stack.imgur.com/OWezf.png This works well when the user opens the email in the same browser where he has been validated but if he opens the mail on his mobile or some other browser and clicks the link, he is taken back to the first validation page where he has to enter his user details again. How can I maintain the same session across different platforms in Django. I know there are some methods to do that like, we need an API which takes an encrypted request id as a parameter which will be included as a token in the access code email link to landing page. The API will decrypt the encrypted request id and then return the payload back associated to the same request id and we can use the data on the Front End to identify the user and resume the access-code verification step. But I donno, how to implement that or if there is any better solution? -

Free text in Select2ListView django-autocomplete-light
:) I'll expose my case as detailed as possible: I'm using the functionality of autocomplete to automatically populate a value that is dynamic into the form. The form has several values, when you fill the first 3 I'm able to run an operation (with those values) and return a suggested value to the user. I needed to adapt a bit the return of parameters but I achieved it with Select2ListView class MyFunctionAutocomplete(autocomplete.Select2ListView): def get_list(self): if not self.request.user.is_authenticated: return [""] try: field1_pk = self.forwarded["field1"] field2_pk = self.forwarded["field2"] field3_pk = self.forwarded["field3"] except AttributeError: return [""] try: ObjField1 = ModelField1.objects.get(pk=field1_pk) ObjField2 = ModelField2.objects.get(pk=field2_pk) ObjField3 = ModelField3.objects.get(pk=field3_pk) return_value = ObjField1.get_result(param1=ObjField2, param2=ObjField3) except (ModelField1.DoesNotExist, ModelField2.DoesNotExist, ModelField3.DoesNotExist): return [""] return [return_value] With this code I'm able to do what I need when the requirements (forwarded value) are present. So far, so good My problem: I cannot ADD any value as an extra option. This value IS NOT a ForeignKey, it's a simple Float. I want the user to be able to use my suggested value or instead just replace it by another value of their choice. Let's say in the dropdown they have the value 3.22221 and they want to write 12.11.

Issue Django Migrations Tree - Deployment Pythonanywhere
guys I have been having this issue when managing Django migrations on deployment, and I would like yo know what approach should I take: I am developing an application using Django and I am using Pythonanywhere to deploy the webapp, I am using sqlite as the database. I understand the Django Migrations work like a tree or a sequence (001, 002), but every time I make a change in a field locally it works fine because the tree have been save and the sequence have not changed, but when deploying the changes through github (having deployed the webapp and calling the migrations and migrate command, which creates another migrations files and sequence), usually I got an error indicating that the migration tree is broken; so I have to go to the app's migration folder and delete them and call again the migrations and migrate command. This is causing me a lot of problems due that I do not want to mess with schema of the database and loss the information. So, It is just me or anyone else is having this issue the migrations tree, not only on pythonanywhere but on others servers. Thank you guys! -
How do I use the Django rest framework to prolong a JWT session token?
I'm using Django 3.2 with the django.auth.contrib app and djangorestframework-jwt==1.11.0. How do I prolong/reissue a new session token upon receiving a request for an authenticated resource and validating the user can access that resource?

Tempus Dominus DatePicker in Django showing one day less when I get the data for edit
I have a Table with all my data, and when I try to edit one row I catch all data to a form, but the datepicker is showing ALWAYS one day less than the one entered. How can I solve this?. I read something about the DateTime from JS but I didn't find anything to solve my problem.

How do I get website to display local time?
If I run this in VS Code, it gives me the correct local time: from time import strftime time = strftime("%H:%M %p") print(time) But if I use the same code in a Django project, my website displays a time which is 8 hours behind local time. from time import strftime,localtime def time_display(request): context = { "date":strftime("%b %d, %Y",localtime()), #DOESN'T DISPLAY LOCAL TIME "time1": strftime("%H:%M %p",localtime()), #DOESN'T DISPLAY LOCAL TIME "time3": strftime("%H:%M %p"), #DOESN'T DISPLAY LOCAL TIME } return render(request,'time_display.html',context) How do I fix it to display correct local time where the webpage is being viewed? -

Why we need to setup AWS and POSTgres db when we deploy our app using Heroku?
I'm building a web api and the training video that I follow at first deploy everything locally then after making sure everything works he is transfering all static files to AWS and for DB he switches from SQLdb3 to POSgres. django portfolio I still don't understand this part why we need to put our static files to AWS and create POSTgresql database even there is an SQLdb3 default database from django. I'm thinking that if I'm the only admin and just connecting my GitHub from Heroku should be enough and anytime I change something in the api just need to push those changes to github master and that should be it. Why after deploying everything locally we are moving to AWS and Postgres setup and do the things from the beginning. Still not get it! Can anybody explain this ? Thanks -
Forms in Django. Drop-down list
In a django (python) project, I have a foreign key model that reflects a form to fill out. Is it possible to make it so that if the user does not find his option in the drop-down list, he has the opportunity to fill in this field, but with his own option (respectively, with saving to the database). And in the future this option will be shown in the drop-down list. Like in the picture. https://i.stack.imgur.com/APDr5.png So that the user can create a new tag if it is not in the drop-down list. What should be applied to implement this idea? What can be found in the documentation? -

Why is the View returning None when I navigate to the payment page in Django?
The rest of the application is working well but a problem arises when I navigate to the payment page, the app returns None. I can't figure out where the error is.

Updating many to many model in Django Rest Framework
I have the following models: class Settings(models.Model): ... category = models.ManyToManyField( Category) hsk = models.ManyToManyField( HSKLevels) class Meta: db_table = 'settings' I can quite easily update my main table via REST. The problem is that I cannot figure out how to update the hsk table with REST. class HSKLevels(models.Model): level = models.PositiveIntegerField(primary_key=True) label = models.CharField(max_length=50) value = models.CharField(max_length=50) class Meta: db_table = 'hsk_levels' This is my serializer: class SettingsSerializer(serializers.ModelSerializer): class Meta: model = Settings fields = ["user","traditional","category", "hsk","audio_download","show_read","show_pinyin","char_size","pinyin_size","start_date","end_date","speed","volume", "char_colors", "pinyin_colors", "global_dash","first_tone","second_tone","third_tone","fourth_tone","fifth_tone","word_selection","limit_selection","hsk_selected","sentence_selection","mem_limit_selection","show_outline","show_character","show_hint_after_miss"] depth = 1 With this setup, I am able to add many to many connections, but I cannot delete any many to many connections. What I'd prefer is if a given connection isn't present - is to delete it. So I'd have a JSON object like this (or alternatively, an array, I am not picky): hsk: { hsk1: true, hsk2: true, hsk3: true, hsk4: true, hsk5: true, hsk6: true, hsk7: true, hsk8: true, hsk9: true, hsk9plus: true, }, And if one of these values is false or not present, it gets deleted. -

Can someone send me an example of programs (views.py, urls.py, template ...) which uses class = "modal fade" to introduce latitude and longitude of a PointField, then search if this point exists with the filter command and display it on a map. I inform you that I use Django and Leaflet. Thank you so much. -
