UpdateVIew form data not getting prepopulated when form is used in Detials View
[Base Update View details][1] [1]: http://ccbv.co.uk/projects/Django/3.0/django.views.generic.edit/BaseUpdateView/ I am trying to have a Update form(updateview) in in my detailView template which updates one of the foreign key object of my detailview's object. I am getting output as expected and logics are working completely fine. I am using updateviewform as popup form but previous data is not getting prepopulated in the form. Views.py file class EducationUpdateView(LoginRequiredMixin,UpdateView): model = Education form_class= EducationCreateForm class PortfolioDetailedView(DetailView): model = Portfolio success_url = 'portfolio:index' def get_context_data(self, **kwargs): context = super(PortfolioDetailedView, self).get_context_data(**kwargs) context['education_form'] = EducationCreateForm() return context template here portfolio is the detailsView object and education is its foreign key {% for item in portfolio.education.all %} <form method="POST" class="form-group" action="{%url 'portfolio:eduupdate' pk=item.pk %}" {% csrf_token %} <div class="form-row"> {% bootstrap_form form %} </div> <input type="Submit" class="btn btn-primary" value="Submit"> </form> pasting this for an idea this is not complete code. The only problem is data is not getting prepopulated into update view form -

How to send an email using a html template that contains javascript django?
I have an email template that is rendering certain datetime strings from django. I would like to render this time based on the user's timezone. To solve this I have opted to use momentjs however once, it seems the javascript in the template is not run and anything wrapped in javascript doesn't appear in the email. Based from this answer https://stackoverflow.com/a/42056995/8513875 email clients don't include external css, I assume it's the same issue with javascript, how would I go about making this recognized. -
Showing instagram follower count on dashboard template
During development I was able to scrape the follower count of my client's instagram page and show it in the dashboard. However, after deploying to Heroku it is not working as expected. I always thought there might be problems with this down the road but it was working for the time being. views.py def dashboard_view(request): def insta_follower_count(): user = "username" url = "https://instagram.com/" + user try: r = requests.get(url).text start = '"edge_followed_by":{"count":' end = '},"followed_by_viewer"' count = (r[r.find(start)+len(start):r.rfind(end)]) except: count = 'Could not fetch followers' return count context = { "insta_followers": insta_follower_count(), } return render(request=request, template_name='dashboard/dashboard.html', context=context) Surely there's a better way of doing this because instagram will block you if too many people load the dashboard view too fast. -

In Pycharm, I can't fetch a JSON file and cannot install fetch
I am working on a Django project in Pycharm. I need to fetch API in the Javascript file, but it gives me an internal server error and error in the console showing the fetch line. It seems like it is not recognizing fetch at all. This is an example of how I use fetch in my code; document.querySelector('#compose-form').onsubmit = function () { fetch('/emails', { method: 'POST', body: JSON.stringify({ recipients: in_recipients, subject: in_subject, body: in_body, }) }) .then(response => response.json()) .then(result => { if (result.message !== "Email sent successfully."){ alert(result.error) } }); }; My code is actually working on Vscode but can't make it work in Pycharm. I tried pip install fetch I got the following error; ERROR: Command errored out with exit status 1: Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Users\bilge\AppData\Local\Temp\pip-install-n1v3op9a\fetch\setup.py", line 6, in <module> description = file(os.path.join(here, 'README.txt')).read() NameError: name 'file' is not defined ---------------------------------------- ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

Algorithm Visualization using Django
I'm building a website using the Django framework. I want to add an algorithm visualization tool. The way I think about it is: I want to create different .py files that will contain the algorithms (example: bubble_sort.py, insertion_sort.py ...) Then I want to create some animations files (using js or CSS), and then feed the .py files to the animation files, in order to separate the algorithm's logic from the animation logic. I have looked on the internet, but I can't find some useful resources. If you have any idea how I can proceed, feel free to suggest them. Thanks, -

Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead. Can anybody help me solve this? -
Two different types of user with different username field types
Default User Model: class User(AbstractBaseUser, PermissionsMixin): avatar = models.ImageField(upload_to='user/avatar', null=True, blank=True) date_joined = models.DateField(auto_now_add=True) username = models.EmailField(unique=True, null=False, blank=False) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) is_employer = models.BooleanField(default=False) is_employee = models.BooleanField(default=False) object = managers.UserManager() USERNAME_FIELD = 'username' REQUIRED_FIELDS = [] class Meta: verbose_name = 'User' verbose_name_plural = 'Users' Employer model that extends from User: class Employer(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, primary_key=True) name = models.CharField(max_length=256, blank=False, null=False) address = models.CharField(max_length=256, blank=False, null=False) fax = models.DecimalField(max_digits=11, decimal_places=2, blank=True, null=True) email = models.EmailField(unique=True, blank=False, null=False) economic_code = models.DecimalField(max_digits=20, decimal_places=2, blank=True, null=True) national_id = models.DecimalField(max_digits=20, decimal_places=2, blank=True, null=True) Employee model that extend from User: class Employee(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, primary_key=True) employer = models.ForeignKey(Employer, null=False, blank=False, on_delete=models.CASCADE) first_name = models.CharField(max_length=50, null=False, blank=False) last_name = models.CharField(max_length=100, null=False, blank=False) national_id = models.PositiveIntegerField(null=False, blank=False) date_of_birth = models.DateField(blank=False, null=False) post = models.CharField(max_length=100, null=True, blank=True) mobile = models.DecimalField(max_digits=11, decimal_places=2, null=False, blank=False) personnel_code = models.PositiveIntegerField(null=True, blank=True) eligible_leave = models.FloatField(default=0, blank=False, null=False) sick_leave_per_month = models.FloatField(default=0, null=False, blank=False) rfid_card_code = models.CharField(max_length=256, blank=False, null=False) I want the employer to be authenticated by email and the employee by national code (username filed). How?
