Bootstrap Modal popup and Django
I'm new to django/bootstrap and currently i'm practising by using an html/css/js template which i downloaded from the internet. I rendered the template with django successfully by following a tutorial. Now i want to configure Login/Register to learn Django authentication. Now when i press Login/Register button (picture1) a popup is displayed. I tried to render loginregister page. <li class="list-inline-item list_s"><a href="{% url 'loginregister' %}" class="btn flaticon-user" data-toggle="modal" data-target=".bd-example-modal-lg"> <span class="dn-lg">Login/Register</span> I've created a views.py file, configured the urls.py file and created an html file in order to display my page and not the popup but unsuccessfully the popup is always displayed.

Django migrate showing Operations to perform instead of performing migration in Django v3.1
I had started to upgrade an old web application from django v2.7 to django v3.1 for my academic purpose. manage.py migrate. Then it showed some successful migration. Then I created a super user by manage.py createsuperuser and tried to login to admin. But after entering the successful credential, it showed an 500 server error. I found that admin migration not yet performed. Then I tried manage.py migrate admin,Then the output like this Operations to perform: Apply all migrations: admin Running migrations: No migrations to apply. I tried many result mentioned in different blogs and forums, but did not work. So I am wondering whether it is applicable to django v3.1. Could anyone help me. -
Django: Pass arguments from other form to submit button
I'm building a simple Django app that lets users track stuff for specific days: It records entries with a name and a date using the upper form. <form action="" method="post" style="margin-bottom: 1cm;"> {% csrf_token %} <div class="form-group"> {{ form.entry_name.label_tag }} <div class="input-group"> <input type="text" class="form-control" id="{{ form.entry_name.id_for_label }}" name="{{ form.entry_name.html_name }}" aria-label="new entry field"> {{ form.entry_date }} <div class="input-group-append"> <button type="submit" class="btn btn-primary">Add</button> </div> </div> <small id="{{ form.entry_name.id_for_label }}Help" class="form-text text-muted">This can be anything you want to track: An activity, food, how you slept, stress level, etc.</small> </div> </form> Below the form, there are quick add buttons that let users quickly add a new entry with a specific name. In addition, I'd like to use the date selected in the form above. I.e., if a user sets a date in the upper form but then clicks one of the suggested buttons, it should still use the selected date for adding the new entry. This is what the code for the suggested buttons currently looks like: {% if entry_counts and entry_dict|length > 0 %} <div class="card" style="margin-bottom: 1cm;"> <div class="card-body"> <div class="card-title">Suggested entries</div> {% for name, count in entry_counts.items %} <form method="post" action="{% url 'app:add_entry_with_date' name form.entry_date.value %}" style="display: inline-block;"> {% … -

Setting Django Allauth as ForeignKey
I'm building an online e-commerce using Django. I want to have my user to log in using social media ( like Facebook and Google). I'm already done doing this using Django Allauth. But the problem is, how can I make it to be foreignkey when placing an order ? Here is my code so far , views.py from django.db import models from django.contrib.auth import get_user_model from products.models import Products User = get_user_model() class Cart(models.Model): user = models.ForeignKey(User, on_delete = models.CASCADE, verbose_name = 'Customer') item = models.ForeignKey(Products, on_delete = models.CASCADE, verbose_name = 'Item') quantity = models.IntegerField(default=1) created = models.DateTimeField(auto_now_add=True) def __str__(self): return f'{self.quantity} of {self.item.title}' def get_total(self): return self.item.price * self.quantity class Meta: db_table = 'cart' class Order(models.Model): orderitems = models.ManyToManyField(Cart) user = models.ForeignKey(User, on_delete=models.CASCADE) ordered = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) def __str__(self): return self.user.username def get_totals(self): total = 0 for order_item in self.orderitems.all(): total += order_item.get_total() return total It gives me an error when adding items to cart. So how can I do this that wetehr the user is using the default django authentication or their 3rd party accoutn like facebook and google, it will work. -

nginx serve both django static files and react static files
Im recently trying to impement nginx to link up my django based backend and react based frontend. Here is my nginx config file: upstream api { server backend:8000; } server { listen 8080; location /api/ { uwsgi_pass backend:8000; include /etc/nginx/uwsgi_params; } location /admin/ { uwsgi_pass backend:8000; include /etc/nginx/uwsgi_params; } # ignore cache frontend location ~* (service-worker\.js)$ { add_header 'Cache-Control' 'no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0'; expires off; proxy_no_cache 1; } location / { root /var/www/frontend; try_files $uri /index.html; } location /static { alias /vol/static; } location /static/rest_framework/ { alias /vol/static; } } However, the issue is that my manage.py collect static will place the django static files into /vol/static however, my react build is in /var/www/frontend/ therefore when I try accessing the default / url, it returns a blank page. However, if i remove the location /static { alias /vol/static; } location /static/rest_framework/ { alias /vol/static; } It will serve my my django admin page without any css. How do i resolve this easily without putting both static files in the same directory? -
Heroku: R15 Error Memory quota vastly exceeded when loading large files
So I am new at deploying Heroku applications. I have built a django application that basically reads from a Machine Learning model (1.3GB). This model is stored as a variable via the pickle.load function: model = pickle.load(url_path) I need this model to be accessed frequently in the application. For example, each user has a the possibility to do a prediction over some stocks. When he uses the prediction functionality we will do basic operations on this ML model. After deploying the django application via Heroku, I receive the Heroku: R15 Error Memory quota vastly exceeded, that corresponds in time with the 'model=pickle.load(url_path)' operation. I believe it is expected since the model that will be stored as variable is 1.31GB and the dyno used has 512MB. I would need a way to use this variable frequently (maybe through a third party or anything else) without having to upgrade to Advanced/Enterprise dynos. This would be really appreciated. Kind regards, Marvin -
Struggling to get Django server to run in virtual environment

User filtering in Django, how to return specific user's data?
Been trying to figure this out for a long time(as in days), but can't understand what to use to return one users "events". A bit new and unfamiliar so would love any help I could get.

Having difficulty Django CBV DetailView to be able to incoporate with Create,Update& Delete View: I have two models, the 2nd model have a ForeignKey from the first one: How can I differentiate their pk value on their urls.py. I encounter error:404 when trying to detailView of the pk on the 2nd model. Thank you very much.

Django Translation (Translate Database Values)
I'm working on a project and they asked me to make the project multilingual. but they don't have specific languages, and I want to handle this in the simplest and smarter way so I thought if I use django-modeltranslation package it will be good for me. things to know: 1- there are a lot of fields that need to translate into a lot of models and columns. 2- I Im working on drf, the front end in another language. things to do : 1- I want to make dynamic serializers to handle the columns that contain translation. ex(name_en, name_fr, name_ar ...etc.) so the serializer should return the "name" key always, not "name_en" or "name_fr". I made some code and worked fine with me but it will be a headache for me and hard to cover all cases and fields that I need to translate. example code : models.py name = models.CharField(max_length=250, blank=True, null=True) translation.py from modeltranslation.translator import translator, TranslationOptions from .models import Category class CategoryTranslationOptions(TranslationOptions): fields = ('name', 'description') translator.register(Category, CategoryTranslationOptions) request_helper.py def check_language(language): if language: return language else: return "en" def check_accept_language_header(headers): is_lang = False if "Accept-Language" in headers.keys(): is_lang = True if is_lang: return check_language(headers["Accept_Language"]) else: return "en" … -
unique=True always raises exception when used with save(commit=False)
I have a model with two fields f1 and f2. f1 has a unique constraint. I have 2 ModelForms, MF1 and MF2, one for each field. In my view, I render & process the two ModelForms. is_valid() calls on both my_MF1 and my_MF2 are fine. When I save my_MF1.save(commit=False) my_MF2.save() I get a "UNIQUE constraint failed" exception on the second save call. The second call considers that the first one has already created a record with some f1 value. When I save my_MF2.save(commit=False) my_MF1.save() everything works fine. Is this the expected behavior or is this a bug? If it is not a bug, it would be impossible to have both f1 and f2 unique. I am using SQLite. -
