Docker/Python/Django astimezone seems to be using DST from past year
I'm converting UTC datetimes to America/Santiago tz using dt.astimezone(my_tz) through a Django manage.py command, but it seems to be using DST from past year.

Error with "input file" in Django. Does not recognize the file
I have problems working with django images, when selecting an image in the django manager everything works correctly, but when creating my own form it does not work. That is, filling the entire form correctly, selecting the file normally, at the time of submitting the form, does not send it and deselects the file you select, and tells me that said field is required. It makes no sense, I select the image, send the form and tell me that the field is required, and the image I chose is deselected. Here my model: class Course(models.Model): instructor = models.ForeignKey(User, on_delete = models.CASCADE) title = models.CharField(max_length = 200) image = models.ImageField(upload_to = 'course') description = models.TextField() users = models.ManyToManyField(User, related_name = 'get_users') created = models.DateTimeField(auto_now_add = True) updated = models.DateTimeField(auto_now=True) class Meta: ordering = ['title', 'created'] Here my view: class CourseCreateView(CreateView): model = Course fields = '__all__' template_name = 'courses/course_form.html' success_url = reverse_lazy('home') More explicit example of the problem: Fill in the form correctly: I click on the "Crear"/Create button, and the following happens: It tells me that the field is required and appears in the "I don't choose the file" input, what is happening? -

How to display the formset in django with TemplateResponseMixin
I keep getting Method Not Allowed: /2/module/ message error when i try to access this page. How can I access the view from this custom class based views. forms.py from django import forms from django.forms.models import inlineformset_factory from core.models import ( Course, Module ) ModuleFormSet = inlineformset_factory(Course, Module, fields = [ 'title', 'description'], extra=2, can_delete=True) views.py class CourseModuleUpdateView(TemplateResponseMixin, View): template_name = 'core/manage/module/formset.html' course = None def get_formset(self, data=None): return ModuleFormSet(instance=self.course, data=data) def dispatch(self, request, pk): self.course = get_object_or_404(Course, id=pk, owner=request.user) return super(CourseModuleUpdateView, self).dispatch(request.pk) def get(self, request, *args, **kwargs): formset = self.get_formset() return self.render_to_response({'course':self.course,'formset':formset}) def post(self, request, *args, **kwargs): formset = self.get_formset(data=request.POST) if formset.is_valid(): formset.save() return render('core:manage_course_list') return self.render_to_response({'course': self.course,'formset': formset}) template.py {% extends "base.html" %} {% block title %} Edit "{{ course.title }}" {% endblock %} {% block content %} <h1>Edit ""{{ course.title }}"</h1> <div class="module"> <h2>Course modules</h2> <form action="" method="post"> {{ formset }} {{ formset.management_form }} {% csrf_token %} <input type="submit" class="button" value="Save modules"> </form> </div> {% endblock %} urls.py path('<int:pk>/module/', views.CourseModuleUpdateView.as_view(), name='course_module_update') I am not sure where the problem is coming from as I tried to use PDB to check on everything. Any assistance will be much appreciated. -
Element of my django forms.py is not defined?
I've got a problem with django with handling forms : I created a form with 2 fields, and I associated it to my view, but it tells me that my fields are undefined. Could you explain me please ? I created a form in my index.html : <form action="/addUser" method="post"> {% csrf_token %} <label> Name of the Employee : <input type="text" name="employeeName", id="employeeName"/> </label> <label> Email of the Employee : <input type="email" name="employeeEmail", id="employeeEmail" /> </label> <button class="btn btn-primary" type="submit">Add User</button> </form> Then I created in views.py def addUser(request): if request.method == 'POST': form = CreationUserForm(request.POST) newEmployee = Employee() newEmployee.name = form[employeeName] newEmployee.email = form[employeeEmail] newEmployee.save() return HttpResponseRedirect(reverse('app:home')) And then I created in forms.py class CreationUserForm(forms.Form): employeeName = forms.CharField(label='employeeName', max_length=254) employeeEmail = forms.CharField(label='employeeEmail', max_length=254) So I don't understand why I get this error : name 'employeeName' is not defined For my point of view it is... I tried with form.employeeName too, but it considered as a non existant attribute. Thank you for helping :)
