How to solve this modelForm Django error?
I'm trying to follow this tutorial about Django on youtube, and I'm writting exactly the same way the teacher writes on the video, but my code is throwing errors that I can't identify. I've already made some search about it, I've made all the imports apparently correctly and I really don't know where to look. My code: from django import forms from django.forms import ModelForm from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm from .models import Profile class UserRegisterForm(UserCreationForm): email = forms.EmailField() class Meta: model = User # When form.save() runs, its going to be saved on the User model fields = ['username', 'email', 'password1', 'password2'] class UserUpdateForm(ModelForm): email = forms.EmailField() class Meta: model = User fields = ['username', 'email'] class ProfileUpdateForm(Modelform): class Meta: model = Profile fields = ['image'] It returns the following error: Watching for file changes with StatReloader Exception in thread django-main-thread: Traceback (most recent call last): File "/usr/lib/python3.8/threading.py", line 932, in _bootstrap_inner self.run() File "/usr/lib/python3.8/threading.py", line 870, in run self._target(*self._args, **self._kwargs) File "/home/isaacrpl7/.local/lib/python3.8/site-packages/django/utils/autoreload.py", line 53, in wrapper fn(*args, **kwargs) File "/home/isaacrpl7/.local/lib/python3.8/site-packages/django/core/management/commands/runserver.py", line 118, in inner_run self.check(display_num_errors=True) File "/home/isaacrpl7/.local/lib/python3.8/site-packages/django/core/management/base.py", line 392, in check all_issues = checks.run_checks( File "/home/isaacrpl7/.local/lib/python3.8/site-packages/django/core/checks/registry.py", line 70, in run_checks new_errors = check(app_configs=app_configs, databases=databases) File … -

Django Axios GET Request not allowed
I'm trying to make a simple, unauthorized request from axios to Django, but it's not working, with result "501 unauthorized". The thing is, this request doesn't require that user is signed in, so I don't know exactly what's the error. my django view: @api_view() @renderer_classes([JSONRenderer]) def main_enterprise_name(request): return Response({'name': Enterprise.objects.get(main_instance=True).name}) The Django URL: path('api/enterprise/main/', views.main_enterprise_name, name='main_name'), Axios config: axios.defaults.xsrfCookieName = "attcsrf" axios.defaults.xsrfHeaderName = "X-CSRFATTTOKEN" const api = axios.create({ baseURL: "http://127.0.0.1:8000", }); api.interceptors.request.use(function (config) { const token = getToken(); if (token){ config.headers.Authorization = 'Bearer '.concat(String(token)); } return config; }); When I make this request in browser, it works just fine, but with axios this fails with unauthorized. -
How can I add a tag <a href=""> to a send email using django and mailgun? [closed]
Using django and mailgun, my email its ok, but the link in my html when it send doesn't look like I need (I mean just to click on a word and redirect to the link), in the email just see the word without a link when you hover it. I don't know what else I can do for this.

Properly escaping strings in raw Django SQL query
Really the root of the problem is poor database design going back to long before I started here, but that problem isn't going to be resolved by the end of the day or even the end of the week. Thus, I need to find a better way to handle the following to get a feature added. I'm forced to deviate away from the Django ORM because I need to build a raw SQL query due to having to write logic around the FROM <table>. We've elected to go this route instead of updating the models.py a couple times a year with the new tables that are added. There are numerous areas starting here where the Django documentation says "Do not use string formatting on raw queries or quote placeholders in your SQL strings!" If I write the query like this: cursor.execute(""" SELECT * \ FROM agg_data_%s \ WHERE dataview = %s \ ORDER BY sortorder """, [tbl, data_view]) It adds single quotes around tbl, which obviously causes an issue, but will correctly construct the WHERE clause surrounded in single quotes. Doing this, will not put single quotes around tbl, but will force you to put single quotes around the WHERE … -
Cannot pass variables to Django 3 method from HTML template
I am a Django newbie who is trying convert and existing HTML based website to Django 3. The only complex piece of this page is a call to a Django method that uses the django.core.mail package and everything works, but, I am trying to pull some data off of the HTML template and pass it to this method. The method works only it sends a blank email. I am trying to pass contact information that the end user would fill out on the form. If I hard code the data into the method it works. I have tried passing the data through urls.py, but, everything I try fails to even parse when I call the method. When I use a request.GET.get everything seems to work, just no data. I was hoping to use some similar to JQuery like the following in the method. name = str(request.GET.get('Name:', '').strip()) email = str(request.GET.get('Email:', '').strip()) msg1 = str(request.GET.get('Message:', '').strip()) with the fields being in the HTML form.

Is there a method to restrict going back in selected views?
I have a question, Adding or inserting an X record redirects me to another page, all good so far. But in Chrome I can go back with the <- button, which makes it difficult for me, because I can make infinite records with different clear IDs, now my question is: How not to regress in different points of view?

Can't create a custom User model in django

But if i input "ab" it didn't do anything it doesn't give me any errors nor add the input to my database.

Django 3.1 can't manage to run views asynchronously
I'm running Django-3.1 (and also I've tried master 3.2 version) in asgi mode via uvicorn. But when I open the url in a couple of browser tabs I see requests to be processed sequentially. It seems like this claim from docs: Under a WSGI server, async views will run in their own, one-off event loop. is also applied to ASGI mode.

DJANGO: Template URL to create new model with ForeingKey as parameter
Best regards!, I'm using a patter like this in Django admin templates to add new models: {% url 'admin:app_model_add' %} where app is an application and model is a model of that app, the problem is this, I have 2 models related by a ForeignKey, lets say I have: class Chapter(TimeStampedModel): title = models.CharField('Título', max_length=250) class Subchapter(TimeStampedModel): title = models.CharField('Título', max_length=250) chapter = models.ForeignKey(Chapter, on_delete=models.CASCADE, verbose_name='Capítulo') So, if I go to admin's Subchapter add it shows a combobox of all existing chapters to which I can link the Subchapter being added and that's just fine, but what I need is, via URL tag show above, I want to pass a parameter through that add URL so the chapter with a given Id be selected as default and the user does not have the need to select it.

Custom model manager gets clobbered by prefetch_related
I have a model and a corresponding model manager: class MyModelManager(models.Manager): def get(self, **kwargs): return super().select_related('group').get(**kwargs) class MyModel(models.Model): name = models.CharField(...) group = models.ForeignKey('Group', ...) tags = models.ManyToManyField('Tag', ...) # ... others ... objects = MyModelManager() The model manager does a select_related() in the get() routine so that I always have the given foreign key field joined (I'll likely be referring to it often). When I call the get() routine, things work just as I expect: obj = models.MyModel.objects.get(pk=1) print(obj.group) # Doesn't hit the database a second time However, if I make a call to something like prefetch_related(), my custom manager gets discarded along the way: obj = models.MyModel.objects.prefetch_related('tags').get(pk=1) print(obj.group) # Hits the database a second time to get the group The reason becomes pretty clear when I print the types: x = models.MyModel.objects print(type(x)) # Yields <class 'base.models.TestCaseManager'> y = models.MyModel.objects.prefetch_related('tags') print(type(y)) # Yields <class 'django.db.models.QuerySet'> My Question Can I get chained calls to return my custom manager instance, rather than the default one? -

I've looked for other questions, but they're just different errors. I've been developing a simple forum app, and now I've come to the part where I can comment on topics. But then I realized that I have been missing the ForeignKey relationship to the topic from the comment. Then, I created a new ForeignKey but as usual, it asks me to give a default value. I was just about to add Blank and Null true, but then my hands just automatically give asd as a default. Now even when I succeed in making migrations with makemigrations, I got this error when making migrate how can I make this right? -
