how to handle authentication error in angular based on data returned from django rest-framework
a login may result in authentication failed by Django due to 'Invalid credentials', 'Account disabled' , 'Email is not verified' , the code looks as below if not user: raise AuthenticationFailed('Invalid credentials, try again') if not user.is_active: raise AuthenticationFailed('Account disabled, contact admin') if not user.is_verified: raise AuthenticationFailed('Email is not verified') I am getting three different responses in three different conditions but 401 status code in all three cases. my login request sends from angular as follow, if (this.loginForm.dirty && this.loginForm.valid) { this.httpService.doLogin(this.loginForm.value).subscribe(data=>{ console.log() if(data['email'] && data['tokens']){ //codes gets executed if everything goes well and authenticate well. ... ... }else{ console.log('data load fail', data) } },error=>{ //line 1 this.toastr.error('Invalid Credentials or email not verified', 'Login Error',); }) }else{ this.toastr.warning('Info!', 'Invalid data provided.'); } } the problem is in all three above authentication fail, my codes come to line 1, and I am not able to toast the failing reason properly although I get the response but HTTP 401 takes me to line 1.

TodayArchiveview is not detected in urls.py(Django)
I created several date-based views in Django, and while views for year and month function as expected, the view to display today is not detected. For instance, if I try to get http://127.0.0.1:8000/blog/archive/2021/jan or http://127.0.0.1:8000/blog/archive/2021/jan/07/ the views will be displayed, http://127.0.0.1:8000/blog/archive/today/ will fail.

Django Error NoReverseMatch at /new_bid/1 Reverse for 'addwatchlist' with arguments '('',)' not found
I am somewhat new to Django. I'm encountering an error that I find very odd. The site allows a user to place a bid (enter a number amount) on an item, similar to ebay. When I enter the number, I get the error "NoReverseMatch at /new_bid/1 Reverse for 'addwatchlist' with arguments '('',)' not found. 1 pattern(s) tried: ['addwatchlist/(?P[0-9]+)$'] This is odd because that area of the code (new_bid in views.py) has nothing to do with the addwatchlist. The addwatchlist in views.py adds this particular item to a list, for that user. It's just so a user can keep track of any items on the site they want to watch. The watchlist function works completely - I can add an item to my watchlist and it's fine. I don't know why this function is interacting with my other function, new_bid, which adds a bid for the item. I know this error usually is related to the url or the way the html template calls the url but I really don't know why they two are interacting. Is it because they both use "id": listingid ? Any help is appreciated! urls.py for relevant urls: urlpatterns = [ path("addwatchlist/<int:listingid>", views.addwatchlist, name="addwatchlist"), path("new_bid/<int:listingid>", views.new_bid, … -

Suddenly getting Validation Error when trying to perform db migration in Django
For weeks I have had no issues making db migrations, and running models. I added a few fields and then I got Validation Error so I removed the fields, but the error remains. I am not sure what the issue is or how to fix it. I've looked into the db entries and there are no NA entries. I removed from the current field any default="NA" but I continue to get the error.

Is it secure to create API in django without rest framework
I've created an app in my django project which works same like API. But for post requests, logins I'm doing something like this. request "GET"(url: example.com/api/get) this returns a csrftoken which is then used by my applications as cookie. request "POST"(url: example.com/api/login), Here frontend application logs in the user. The csrftoken from example.com/api/get is used in cookies and same is used as csrfmiddlewaretoken in post data. My question here is, it is secure to create API like this and use instead of Django RestFramework. Any suggestion will be appreciated.THANK YOU -

Superuser doesn't work after unapplying migrations in Django
I was having some trouble (errors) with old migrations in my auction site project, so I decide to run python manape.py migrate auctions zero to unapply all the migrations and apply new ones, and it worked. However, after I did it I couldn't use my superuser account to manipulate the models in the admin/ url anymore. In fact, I couldn't use any other account -- this website I'm working on allows the creation of profiles by the user, and before I unapply all the migrations it worked perfectly. But now, if I try to log in with an existing account created for testing purposes, I receive this error message (that I wrote): But I was expecting that to happen, since I (if I understood well) cleared the user database when I unapplied the migrations. But when I try to create a new user, no matter the username or password, I get this error (that I also wrote): How can the username be already taken if it is completely new? These errors appears no matter what I do, even when I try to login with the superuser. When I try to create a new superuser I also have problems, like this … -
Could someone please provide a link to a Django + Javascript basic project?
Could someone please provide a link to a sample Django project that I can download and build off. To be specific, I am going to create a website used for a business application on a mobile device. The web page will have a login. When logged in, the user will be presented with a few menu options. The user can click between the menus without the page reloading. All will be done with Ajax. The user will enter data, scan/search and submit forms. The submitted data will be sent to an external application (ERP system). I have created several projects in the past, but they become difficult to scale and manage. In my previous apps, I used Flask and had everything in a single html file including the javascript. It works, but it isn't great. I'm trying to take things to the next level. I have spent a bunch of time researching google but find several different directions to take. I learn best, by having a basic example and then reverse engineering how it works. -

I'm really new to Python3, Django & Wagtail and am trying to create an ArticlePage Model with a StreamField block used in it, and have run into problems and am getting an error: AttributeError: 'CharField' object has no attribute 'stream_block' error. I have no idea what I'm doing wrong? I'm obviously doing something wrong but have no idea what? Here's the model.py code: articles/models.py: from modelcluster.fields import ParentalKey from wagtail.core import blocks from wagtail.core.models import Page, Orderable from wagtail.admin.edit_handlers import FieldPanel, StreamFieldPanel, MultiFieldPanel, InlinePanel from wagtail.core.fields import StreamField from streams import blocks from wagtail.core.fields import RichTextField from wagtail.images.edit_handlers import ImageChooserPanel from wagtail.search import index ### Flexible Page # Create your models here. class ArticlePage(Page): subtitle = models.CharField() body = RichTextField() date = models.DateField("Article date") team_member = models.CharField() feed_image = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+' ) search_fields = Page.search_fields + [ index.SearchField('body'), index.FilterField('date'), index.FilterField('subtitle'), ] template = "articles/article_page.html" #ToDo: add StreamFields content = StreamField( [ ("team_member", blocks.TeamMembersBlock()) ], null=True, blank=True, ) subtitle = models.CharField() content_panels = Page.content_panels + [ FieldPanel("subtitle"), FieldPanel('date'), FieldPanel('body', classname="full"), InlinePanel('related_links', label="Related links"), StreamFieldPanel("team_member"), ] promote_panels = [ MultiFieldPanel(Page.promote_panels, "Common page configuration"), ImageChooserPanel('feed_image'), ] # Parent page / subpage type rules parent_page_types = ['articles.ArticleIndex'] subpage_types = [] … -
