Django and Postgres "does not exist" when add new relation
Hi I'm havin some problems with Django and Postgres. Here's the model I'm working on: class UserMessage(models.Model): ... replied_by = models.ManyToManyField("users.User", related_name="replied_by_users", default=None, blank=True) When I add the field replied_by and perform the new migrations, all works but when I try to access to the model instances from database, it raised the following error: ProgrammingError at /admin/moments/usermoment/ relation "app_usermessage_replied_by" does not exist LINE 1: ...t"."event_id", "app_usermessage"."end_at" FROM "... And that's because there were already some instances before adding the replied_by field, but since I set the new field to None as default, it needs to ignore them. Here's a snippet of migration file: migrations.AddField( model_name='usermoessage', name='replied_by', field=models.ManyToManyField(blank=True, default=None, related_name='replied_by_users', to=settings.AUTH_USER_MODEL), ), How can I solve this problem without losing database data? Of course I'm in development mode, are there any good practice that I'm missing to handle database when you add a new relation. Thank you -

Django cannot find template, app is in installed_apps and backend DjangoTemplates is enabled
Inside of a page in my templates folder, I tried using an include statement in a for loop, like so: {% for model_othermodel in model.othermodels.all%} {% include othermodels.html with othermodel=model_othermodel %} {%endfor%} At first, I had the issue that it complained there was no key/value being sent to the other template, which was that othermodel=model_othermodel looked like other_model = model_othermodel. However, after that, I had the issue that it could not find the included html file (the file name is correct), for which the error problem would show me the base.html file that each page extends. (I will be using django_app to refer to the app folder) I got the error message: In template path\root\django_app\templates\base.html, error at line 0 No template names provided My base.html file is just a file for bootstrap that every other html file extends. My project structure looks like this: root/django_app root/django_project root/django_app/templates I tried adding the template path directly to 'DIRS' in TEMPLATES, such as so: DIRS = [os.path.join(BASE_DIR, django_app/templates/)] with variations such as django_app/templates, /templates/, /templates, etc. After that, I heard a suggestion to reorder my INSTALLED_APPS list, which is currently: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_extensions', 'django_app', ] to … -

Django form design
How can I make my form looks better? A few questions: How can I make the checkbox and buttons beside Favourite, Photo and Audio. And how can I change the design of the "Choose File" button to the same design as the "Save" and "Cancel" buttons? Can I show the image and audio after uploading it? BTW, I am using crispy form and Bootstrap 4. The html {% extends "base.html" %} {% block content %} <form method="POST" enctype="multipart/form-data"> <div class="mx-auto mt-4" style="width: 600px;"> {% csrf_token %} {{ form.as_p }} <div class="text-center"> <input type="submit" value="Save" class="btn btn-outline-info"> </div> </div> </form> {% if journal %} <div class="text-center"> <a href="{% url 'journal_detail' journal.id %}"><button type="button" class="btn btn-outline-info">Cancel</button></a> </div> {% else %} <div class="text-center"> <a href="{% url 'journal_list' %}"><button type="button" class="btn btn-outline-info">Cancel</button></a> </div> {% endif %} {% endblock %} -
Why does the form validation fail in this django formset?
I have been trying to make a django formset for giving feedback for assignments in a rubric style, where a form is generated for each criteria in an assignment, with the submissionID being automatically assigned, and the user selects what level the student has met a criteria to, and gives a comment about the criteria. Example: The problem I'm facing is that submitting the form does not do anything and just seems to refresh the current page, and I've tried everything I can think of to solve the problem, but the only thing I've managed to find out is where it is going wrong, which is at the line if form.is_valid(), which is returning false as it seems to be getting no forms passed to it for some reason. The expected result of the code is that when a post request is sent, it loops through the submitted forms, sets the submissionID, and saves the forms. So far I have tried doing some debugging by printing variables at different points of the code but mainly the line before it fails. Prints tried: formset: `(Hidden field TOTAL_FORMS) This field is required.(Hidden field INITIAL_FORMS) This field is required. ` Number of forms … -
Combine multiple django forms into one
I'm working with a django(4) project, Where I have two forms and want to combine them into one to display in my template with custom html not by sing {{form}} syntax.

Why django translations don't work in celery task
I'm having problems with django text translations. My translation works fine in serializer, not in celery task. I have one "Person" model. There are 3 fields in the Person model. One of the fields is gender. The genders are defined in the "enums.py" file. In the serializer, the "get_gender_display()" method of the "Person" model works fine, but when I do the same in the celery task, it does not translate. It doesn't work even though I specify activate("tr") in the Celery task. I call the celery task from the serializer's create() method enums.py from django.utils.translation import gettext_lazy as _ class GenderTypeEnum: FEMALE = 1 MALE = 2 UNKNOWN = 3 types = ( (FEMALE, _("Female")), (MALE, _("Male")), (UNKNOWN, _("Unknown")) ) models.py from django.db import models from .enums import GenderTypeEnum from django.utils.translation import gettext_lazy as _ class PersonModel(models.Model): name = models.CharField( max_length=75, verbose_name=_('Name') ) last_name = models.CharField( max_length=75, verbose_name=_('Last Name') ) gender = models.PositiveIntegerField( choices=GenderTypeEnum.types, default=GenderTypeEnum.UNKNOWN, verbose_name=_('Gender') ) tasks.py from celery import shared_task from .models import PersonModel from django.utils.translation import gettext_lazy as _, activate, get_language @shared_task def test(): activate("tr") qs = PersonModel.objects.all() activate("tr") print(get_language()) # --> tr for obj in qs: print(obj.get_gender_display()) # --> always english, not translated serializers.py from rest_framework … -
Django debug toolbar not showing
My file directory system I have attached my file directory system. I have tried removing all *.pyc files as asked in some of the threads on the same topic, but the toolbar still doesn't show. The following is my webpage code: <html> <body> {% if name %} <h1>Hello {{ name }}!</h1> {%else%} <h1>Hello Dude!</h1> {% endif %} </body> </html> I tried adding mimetypes, adding the following code, and even editing the registry editor, but none of them are working. DEBUG_TOOLBAR_CONFIG = { "INTERCEPT_REDIRECTS": False, } No matter what I do, the browser console displays the following (though when I sometimes change the code the error doesn't get displayed, but neither does the toolbar). I'm using MS Edge, just in case it helps. Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec. toolbar.js:1 When I try importing django in my virtual env, it says that there is no module called 'django'. I've tried all methods possible, but nothing seems to be working. -

Migration fails when using GeoDjango's PointField in a model

404 bad request with Django send blob to server side using MediaStreamRecorder.js
I am using MediaStreamRecorder.js to make an audio recording. After recording, it will save it to the database. However, I receive a 404 bad request . When I try to print the blob value in views.py, it gives me none. I tried many solutions but still cannot fix it. I really need some help. The first thing I used to send blob is xhr var csrftoken = getCookie('csrftoken'); var xhr = new XMLHttpRequest(); console.log(xhr) xhr.open('POST', '/record-audio/', true); xhr.setRequestHeader("X-CSRFToken", csrftoken); xhr.setRequestHeader("MyCustomHeader", "Put anything you need in here, like an ID"); xhr.send(blob); Currently I am using fetch but still getting the same error. chat_script.html -> with js functions function sendData(blob) { const csrf_token = getCookie('csrftoken') fetch('/record-audio/', { headers: {"X-CSRFToken": csrf_token}, method: 'POST', body: blob, }); console.log('success') } sendData(blob) For the '/record-audio/' in xhr.open('POST', '/record-audio/', true); and fetch('/record-audio/', I actually type in only '/record-audio', but it keeps giving me the error Not Found: /record-audio/record-audio/ urls.py path('record-audio/',views.record_audio,name="record_audio"), record.html {% load static %} {% block content %} <h1>Recorder</h1> <section class="experiment" > <br> <h3> Send Message: Speech to text </h3> <form method="post" enctype="multipart/form-data" action="{% url 'record_audio' %}"> {% csrf_token %} <button id="start-recording">Start</button> <button id="pause-recording" disabled>Pause</button> <button id="resume-recording" disabled>Resume</button> <button id="stop-recording" disabled>Stop</button> <!-- <input type="submit" value="save file"> …
