How to loop over Chart.js with Django list view
I am using a Django List View, and I am trying to iterate through multiple objects and display percentage values in a Chart.JS gauge. However, although I am iterating the names of the gauge id's by using a for loop counter, I am only ever getting the first iteration of the chart.js object rendering on my screen. My initial thoughts are that similar to how I am dynamically creating new canvas ids for the chart.js objects, I should be doing a similar thing for the variable I am trying to pass into the chart object e.g. reduction overall, but I am not having any luck. Your feedback is welcome. Views.py class PerformanceDetailView(ListView): template_name = 'performance_detail.html' model = Performance context_object_name = 'performance' def get_queryset(self, **kwargs): code = self.kwargs.get('code') return Performance.objects.filter(code=code) Performance_detail.html <section class="projects pt-4 col-lg-12"> {% for item in performance %} <div class="container-fluid pt-2 col-lg-12"> <!-- Project--><div class="project" > <div class="row bg-white has-shadow" style="height: 14rem"> <div class="left-col col-lg-2 d-flex align-items-center justify-content-between"> <div class="project-title d-flex align-items-center"> <div class="has-shadow"><img src="{% static 'img/avatar-2.jpg' %}" alt="..." class="img-fluid"></div> </div> </div> <div class="right-col col-lg-2 align-items-center vertical-center"> <div class="text"> <h3 class="h2 pt-2">{{item.brand}} {{item.style}}</h3> <p class="text-muted">{{item.package_type| capfirst}} package, round {{item.testing_round}}</p> <p class="text-muted">Item size: {{item.size}}</p> </div> </div> <div class="right-col col-lg-8 … -

Order_by the First Value in a Many to Many Field without duplicate entries
I have seen similar questions being asked for the same like Django order_by many to many relation and order_by on Many-to-Many field results in duplicate entries in queryset. But both of them and many more can't seem to answer my question.I have my models as follows. class TeamMember(common_models.CreateModifyModel): user_id = models.CharField(max_length=50, validators=[validate_ObjectId]) lms_user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) team = models.ManyToManyField(Team) class Team(common_models.CreateModifyModel): name = models.CharField(max_length=50) team_type = models.IntegerField(choices=team_type_choices, null=True, blank=True) is_active = models.BooleanField(default=True) The team variable has a many-to-many relationship with my model. I want to order_by the users where name inside the Team model is empty. My first approach was a naive one i.e queryset = self.get_queryset().filter(lms_user__email__in=[item.get('email') for item in email_res['response']]).order_by('team__name') the order_by in the end is not working and is giving duplicate entries for a user with multiple teams as it should. I came across Annotate and Subquery methods in Django and some of them introduced the Case-When to deal with this problem. The only thing that I NEED is to list the users with empty team names on the top AND for users that are assigned to multiple teams I want to get the first_instance of their team object which will avoid the duplicate user entries that … -

Django Error "django.core.exceptions.ValidationError: ['“h” value has an invalid format. It must be in YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ] format.']"
I added a DateTimeField to one of my models but forgot to provide a default value in my models.

Django cumulative value displayed in template
I’m new to Django and Python and have been plugging through Python Crash Course. I have finished that and now have been making my own Django project, adding some extra bits in. Currently, I have a table of entries from my model which I am displaying with a template, each entry in the table has a time and some other data. What I would like is the value for the cumulative time in a column, next to each entries time ie Lesson Lesson time cumulative time Lesson1 0.5 0.5 Lesson2 1 1.5 Lesson3 1.3 2.8 I’m just really stuck on how to get this done, I have looked at lot’s of stack overflow and tried various ways that I just can’t get to work correctly. Looking at other examples they use annotate() and cumsum, but I’ve not been able to get that to work. I’ve done count and sum of other values but this has got me stuck. I think I need to loop over it in my view, but not sure how to associate each value to a cumulative time. Any help would be greatly received. Also, sorry this isn't very well written or succinct, programming doesn't come naturally … -

django deployment on-premise with license
I've developed a Django webapp that I have hosted on Azure. Now, my customer wants to deploy it in his customer environment at enterprise level. So, I want to add a license to this on-premise webapp. The problem is that since I've to deploy the python code itself adding a license check is almost useless. I could not find a way to compile the Django python code either. Does anybody have a solution to this licensing issue and, on-premise Django webapp deployment experience/suggestions? Can using docker be a solution? -

CSRF validation works from Postman but not React/Axios
It's honestly a catastrophic blow to the ego I haven't already figured this out--spent 6 hours so far... I have a React app running off a Django Rest Framework backend. For the password reset functionality I am using Django's builtin view (auth_views.PasswordResetView). I have a form in React that accepts an email and sends a post request to reset the users password. The way I send the data in postman is: Url: http://192.168.0.85:8000/reset_password Body: {'email': 'blabla@bla.com'} Headers: {'X-CSRFToken': OGH9iUEtGPqntMYifQ5kiin2ufV9tK39tbp9Wmh6tLST0DXCXSkY8mOvyq5AjjnZ} ...and it works like a charm! Until I try to replicate the same exact call using axios in React: axios.defaults.xsrfCookieName = 'csrftoken'; axios.defaults.xsrfHeaderName = 'X-CSRFToken'; axios.post('http://192.168.0.85:8000/reset_password',{'email': 'blabla@bla.com'},{headers})) ...this results in a 403 error with this message from the backend: WARNING:django.security.csrf:Forbidden (CSRF cookie not set.): /reset_password I've spent 6 hours googling and experimenting and can't figure out for the life of me why the Axios request would be any different than the Postman one. This problem is particularly infuriating because @csrf_exempt won't work on the django builtin views. -
CropperJS : Images stored in server (Django)
How to crop Images stored in server? I'm not using a form since I'm not uploading the image. How can this be done? Django View from .models import Image def main_view(request): obj = Image.objects.get(pk=1) context = {'obj':obj} return render(request, 'main.html',context) HTML + CROPPERJS <div> <img src="{{obj.file.url}}" id="image" width="400px" > <button id="button">Crop</button> </div> <script> const image = document.getElementById('image'); const cropper = new Cropper(image, { aspectRatio: NaN, crop(event) { console.log(event.detail.x); console.log(event.detail.y); console.log(event.detail.width); console.log(event.detail.height); console.log(event.detail.rotate); console.log(event.detail.scaleX); console.log(event.detail.scaleY); }, }); (Ajax logic to send the cropped image to the server) -
what makes FormView a better fit/choice than Createview?
just in general, i usually use and see people use "CreateView" that saves automatically to the data base, while the save "FormView" needs to be triggered in form_valid function, But, beside that i was wondering: is there other uses of "FormView"? better uses of form_valid? does both "CreateView", and "FormView" do the same job (in general)? what are the mean differences/cases? thanks for the explanations. -
How to submit create view with ManytoMany model
