Why django don't reset UserFactory username in setUp when full test suite is run?
I have a UserFactory like this: class UserFactory(factory.django.DjangoModelFactory): class Meta: model = settings.AUTH_USER_MODEL username = factory.Sequence(lambda n: f'user_{n}') and a test class like this one: class MyClass(TestCase): def setUp(self): self.user1 = UserFactory() self.user2 = UserFactory() print(self.user1) print(self.user2) print(User.objects.all()) def test1(self): print('TEST1') def test2(self): print('TEST2') When I run the test for this class, I got something like this: user_0 user_1 <QuerySet [<User: user_0>, <User: user_1>]> TEST2 .user_2 user_3 <QuerySet [<User: user_2>, <User: user_3>]> TEST1 What I want to know is why the username of UserFactory is not reset to user_0 after the 1st test since the setUp method is executed before each ? -
django-rest-auth: How to send custom user in login response?
So, I implemented custom user login and registration using django-rest-auth and I'm having a problem. After login the api is sending me a response like this: But my user model looks different: class User(AbstractUser): username = None id = models.UUIDField('ID', default=uuid.uuid4, primary_key=True, editable=False) email = models.EmailField('Email Address', unique=True) name = models.CharField('Name', default=None, blank=True, null=True, max_length=255) role = models.CharField('Role', max_length=255, default='CLIENT') USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] objects = CustomUserManager() def __str__(self): return self.email I'd like to have those fields in my response, especially the "role" field.

Rendering static images from a markdown file
I am having difficulty trying to render markdown files with Django, specifically static files referenced in the markdown file. After converting the markdown file into html and injecting it into a template, I cannot get the images to appear. I have tried regex replacing the src call with proper static calls after the markdown to html conversion but it does not work. Is there a specific way this can be done? A test .md file is below with three different ways to try and load the image (markdown and html which is then regrex replaced, and hardcoded static call in the md file). All of these do not work. The image does show if the static call is in the template so it is not an issue of not finding the image file. It just seems the static call is not being engaged. The browser has the following output, <img src="{% static " images="" django_reinhardt.jpg"="" %}"="" alt="Django" title="Django" width="500"> The view to convert the md file for injection is: class MdPageView(TemplateView): md_file = "test.md" template_name = 'md_viewer/md_base.html' def get_context_data(self, **kwargs): f = open(os.path.join(os.path.join(settings.BASE_DIR,'markdown'), self.md_file)) file_content = f.read() f.close() md = markdown.Markdown(extensions=[ 'markdown.extensions.extra', 'markdown.extensions.codehilite' ]) body = md.convert(file_content) ## Convert html … -
I've used ArrayAgg() django model function, it works when I use one column but now two columns. Why?
I have two models. The **Teachers** model and **Courses** model. On the Courses model, I have a foreign key referencing the primary key in the Teachers model. I want to do a **query** that picks all the teachers and for each teacher to have a list of courses they created. I want I'm getting is it just picks the course description but when I add ArrayAgg another field like ArrayAgg('coursename', 'coursedescription'), I get an error. I can solve it with raw SQL but I can't figure it with django models. I'm getting this enter code here { "id": 1, "firstname": "Andrew", "second": "Njaya", "course_teachers": [ "Fundermentals of Algebra", "Fundermentals of Algebra", "Fundermentals of Algebra" ] }, { "id": 2, "firstname": "Kevin", "second": "Odhiambo", "course_teachers": [ "Fundermentals of Algebra", "Fundermentals of Algebra" ] } What I want is or it's equivalent { "id": 1, "firstname": "Andrew", "second": "Njaya", "teacher_courses": [ {coursename:"Algebra","coursedescription":"Fundermentals of Algebra"}, {coursename:"Algebra","coursedescription":"Fundermentals of Algebra"}, {coursename:"Algebra","coursedescription":"Fundermentals of Algebra"}, ] }, { "id": 2, "firstname": "Andrew", "second": "Njaya", "teacher_courses": [ {coursename:"Algebra","coursedescription":"Fundermentals of Algebra"}, {coursename:"Algebra","coursedescription":"Fundermentals of Algebra"}, {coursename:"Algebra","coursedescription":"Fundermentals of Algebra"}, ] -
DJoser with Elastic Beanstalk API
I have a Django project where I'm using Djoser for authentication. While I run things locally all my endpoints work just fine, however, once I use the API on Elastic Beanstalk I am able to create a user, get an authentication token, but I cannot log in. It says 'authentication token not provided'. The frontend is still running locally, the same request being used, and I see the token is passed through the headers: getUserInfo: ({ commit, dispatch }, data) => { console.log(data); axios.defaults.headers = { Authorization: "Token " + state.authToken, }; axios .get( "http://elasticbeanstalk.com/auth/users/me/" ) .then((response) => { commit("SETUSERINFO", response.data); commit("SETAUTHTOKEN", data["auth_token"]); // dispatch("getFollowers"); localStorage.setItem( "auth_token", JSON.stringify(data["auth_token"]) ); dispatch("getUserTweets"); dispatch("getFollowers"); }) .catch((error) => { console.log(error); }); } -

Django Likes count not showing any changes in the Post

Downloading file from local folder using vue
Few hours ago I noticed that <a href='path' download></a> don't work in vue, just before I wanted to finish my project. I've searched for a solution for almost 4h, but I didn't find anything, that's why I'm here. I would like to simply download files (pdf, doc, docx) from my local folder docs on the server with vue. Here is the folder tree: |--src |--app.vue |--docs |--file.doc |--file.pdf |--file.docx So there is the Template part: <v-row justify="center"> <v-col v-for="(docs, i) in info" :key="i" cols="10" > <v-card> <v-row> <v-col cols="10" > <v-icon large>mdi-file-document-outline</v-icon> {{ docs.name }} </v-col> <v-col cols="2" > <v-row><a :href="docs.file" download><v-icon color="green" large>mdi-download</v-icon></a></v-row> </v-col> </v-row> </v-card> </v-col> </v-row> ...and the script section: import axios from 'axios' export default { data () { return { info: null, } }, mounted () { axios .get('http://localhost:8080/Project/Orders/') .then(response => {this.info = response.data.data}) .catch(error => console.log(error)) }, } I'm using axios to get data from database (id, name, file=path) with Django (backend). I'd like to download files from docs folder without Django, but if anyone thinks it would be better idea to use it I'll be greatful too. -
DNS (Google Domains) is redirecting to Port instead of the Root
Been working on this for a while and could use an assist. I think I messed up. I set up a small Django application on AWS Lightsail. During set up, the tutorial instructed me to run the server at Port 8000. I ran manage.py and everything worked fine. Next, I set up the Apache server per the AWS instructions. Everything works fine when I open http:// (insert public IP address) Since I'm no longer running the server at Port 8000, I deleted that port from the Firewall. -
Django modelformset_factory overrides old instead of adding new images
