Django: Is there any way to copy a form in the admin to a user-facing page?
https://github.com/mikejohnsonjr/django-powerdns-manager ^ I want to copy the form for adding and editing and deleting new zones. It's a bit counter-intuitive. For example, importing any zone form (like NsRecordModelForm or ARecordModelForm) on a user-facing page will result in being able to add any record (with no styles), rather than a specific type of record. https://github.com/mikejohnsonjr/django-powerdns-manager/blob/master/src/powerdns_manager/admin.py Here is the ugly (no styles) anyzone-ModelForm form: https://i.imgur.com/F6Zcs10.png And here is the admin interface for performing CRUD operations on zones: https://i.imgur.com/5LReNsq.png Can anyone help? Thanks in advance. -

NoReverseMatch exception when creating integration test for REST API with Python Django
I've created a REST API accepting a POST request in Django. The request itself works great when calling from a React front end, there should be nothing wrong with the API itself. I want to create integration test for the API. I've written the below test, which is basically copy/paste from the Django Documentation adapted to my API: from django.urls import reverse, path from rest_framework import status from rest_framework.test import APITestCase class SendLoginEmailTest(APITestCase): def test_post_withValidData_loginEmailIsSent(self): url = reverse('send_login_email') data = {'email': 'validemail@email.com', 'token': '4d4ca980-cb0c-425d-8d2c-7e38cb33f38e'} response = self.client.post(url, data, format='json') self.assertEqual(response.status_code, status.HTTP_200_OK) I run the test using the command: python3 manage.py test The test fails with the following exception: django.urls.exceptions.NoReverseMatch: Reverse for 'send_login_email' not found. 'send_login_email' is not a valid view function or pattern name. Any ideas what I'm doing wrong? -
Django how to convert FileField & DateTime field to JsonResponse?

Django OneToMany relation on existing database
I'm working on a legacy database constructing an API, and I need to create some respect some hierarchy that is already in place. The API is meant to be read only, so I'm trying to avoid creating any new table in this cenario. There's a table called regionsubregion that has the idregion and idsubregion I need for creating the relation between Region and SubRegion . I was doing simple ForeingKeys like so: class Region(BaseModel): id_region = models.IntegerField(primary_key=True, db_column="idregion") name = models.CharField(verbose_name="Nome", db_column="description", max_length=80) uf = models.CharField( verbose_name="Unidade Federal", db_column="ufe_sg", max_length=2 ) class SubRegion(BaseModel): id_subregion = models.IntegerField(primary_key=True,db_column='idsubregion') region = models.ForeignKey( "Region", on_delete=models.DO_NOTHING, related_name="subregions" ) name = models.CharField(verbose_name="Nome", db_column="description", max_length=80) The Tables in question are region and subregion. But subregion table has no data related to the id of its parent region, this information is contained in the table regionsubregion, like so: idregion idsubregion 8 3 8 10 8 26 9 23 9 28 9 41 9 8 10 18 Before there was a Many to Many relation between those two, but now it is only 1-to-N (One Region has many Subregions, One subregion is bound to one region only). Since the relation information is in an entirely different table and I'm … -
Upload video on website and keep it secured ? (Django)
For the school project I've been working on, the client asked for video uploading, but due to privacy, they wanted to secure the video to be shown only for signed users. I made the page to be secured, but uploading video was a bit of problem. I was thinking about youtube prvacy enhanced mode, but because various users will be uploading, this wasn't a good way to do. So, I was wondering, Can server / host or webpage handle the size of the videos uploaded by users ? Would html5 video tag be ok for this? Would there be any other good option in this case ? -

Django Role Based Authentication based on Permission on URL instead of Permission on model class
I have studied abut Django Authorization. My observation is basically Django Authentication module works fine for Authorization based on role-based Authentication based on Permission on a Model instance. But In Spring framework I found here same role-based Authentication based on Permission on URL or actually relative URL or URL pattern here like .antMatchers("/user/**").hasRoles("USER", "ADMIN") in following code snippet. Here is a code snippet of Spring Framework: @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/static","/register").permitAll() .antMatchers("/user/**").hasRoles("USER", "ADMIN") // can pass multiple roles .antMatchers("/admin/**").access("hasRole('ADMIN') and hasIpAddress('123.123.123.123')") // pass SPEL using access method .anyRequest().authenticated() .and() .formLogin() .loginUrl("/login") .permitAll(); }``` Is there any way or library in Django Similar way of Spring for Authorization based on Permission on URL? Thanks. -
