Django Ckeditor Automatically Save Data to Server / Backend
How would I go about automatically saving data from frontend ckeditor to the backend without reloading the page. I tried using ajax to make this work, but I am unable to send the updated content to the backend. Additionally, the javascript on change method is triggering 2x per single input. For example if I type "A" for a new input in ckeditor, it'll trigger twice for some unknown reason. Approach 1 - HTML / JS (Click "submit" button when change is detected) <form class="pt-2" action="#" method="POST" id="designer-form"> {% csrf_token %} {{ form.media }} {% for field in form %} {{ field }} {% endfor %} <div class="mt-4 flex justify-end space-x-4"> <button type="submit" id="submit"> Save Changes </button> </div> </form> <script> CKEDITOR.on('instanceCreated', function(event) { let editor = event.editor; editor.on('change', function() { setTimeout(function () { document.getElementById("submit").click(); }, 2500); }); }); </script> Approach 2 - HTML / JS (Serialize Data) <form class="pt-2" action="#" method="POST" id="designer-form"> {% csrf_token %} {{ form.media }} {% for field in form %} {{ field }} {% endfor %} <div class="mt-4 flex justify-end space-x-4"> <button type="submit" id="submit"> Save Changes </button> </div> </form> <script> CKEDITOR.on('instanceCreated', function(event) { let editor = event.editor; editor.on('change', function() { let data = editor.getData(); setTimeout(function (){ $.ajax({ … -
Check user doesn't already have this object before displaying CreateView - Prevent them from creating multiples
I've been slowly learning Django over the past few weeks, and applying it to a work prototype. I have a simple profile model called Applicant. This stores personal fields for the a customer. It contains a OnetoOne field linking to the Django Auth User model, as I'm using this to require login and control access to data. I'm struggling to figure out how to perform checks within View Classes (seemed easier within View Functions), I need a way to check if a user already has an Applicant entry before presenting them with the CreateView form. Previously to display this Applicant profile data (created via admin page), I used the get_object_or_404 within the DetailView.get_object to catch Http404 and return None if they didn't have a profile. This would then provide a link to the Create page. I need to implement the reversed logic on the CreateView, to protect them from creating multiple Applicant entries. Any suggestions would be great, even just to point me in the right direction. Code I used for DetailView: class ApplicantProfileDetailView(LoginRequiredMixin, generic.DetailView): model = Applicant template_name ='profile.html' def get_object(self, queryset=None): try: return get_object_or_404(Applicant, user=self.request.user) except Http404: return None <h1>Applicant Profile</h1> {% if applicant %} ... {% else … -
Letting the user Select a Font-Family in Django Web Application
I am in the process of building a Django Web Application that lets a user customize different CSS options for their webpage in the Django Admin Web Interface. Currently, the admin user has the option to change the color, background-color, and font-family. I used Django forms to create a Color Selector Widget so the user doesn't have to type in a hex color value and type in the name of a font. I am trying to create a widget to let the user select a font from a list of font-familys. I've looked into tkinter and listboxes but it appears it is best for GUIs. Should I just create a list of choices and populate it with a bunch of fonts? I have been having a hard time coming up with a viable efficient option. forms.py class cssForm(ModelForm): class Meta: model = styleEditor fields = "__all__" widgets = { "Link_Color": TextInput(attrs={"type": "color"}), "Link_Background_Color": TextInput(attrs={"type": "color"}), } models.py class styleEditor(models.Model): Link_Color = models.CharField(max_length=7, default="#000000") Link_Font_Style = models.CharField(max_length=15, default="Brush Script MT") Link_Background_Color = models.CharField(max_length=7, default="#F5F5F5") admin.py @admin.register(styleEditor) class styleEditor(admin.ModelAdmin): form = cssForm -
Django how to compere calculated fields in query
Is it possible to get data from another table in a query by comparing calculated values? Like for example, by calculating using the minimum and maximum price values and getting Url's to them from another table. My models look like this: class Product(models.Model): id = models.CharField(..) price = models.FloatField(..) url = models.CharField(..) ..... class ProductHistory(models.Model): ProductID = models.ForeignKey(Product, on_delete=models.CASCADE, to_field='ProductID', db_column='ProductID') price = models.FloatField(..) date = models.DateTimeField(..) My request looks like this query = HistoryPrice.objects.filter(ProductID=products).filter(query_price) \ .annotate(dt=Trunc('StartDate', frequency)) \ .values('dt') \ .annotate(max_price=Max('Price'), min_price=Min('Price')) \ .order_by('dt') But i want to get Url from Product table for each max_price for given period. How can i achieve it -

where is the data saved during Django stack development
Maybe this is a super silly question. I am new with Django stack web app development. I am following Django tutorial on MDN. I entered information to the backend database via the admin page. But some error happened later so I had to uninstall pyenv and restart. I wonder if I can find all the information I entered which is not on any project documents. Thanks. -

Uploading fixtures to django running within docker container in an AWS EC2 instance
So I have a a few operations I need to perform on a running instance - kind of a one-off thing. That involves uploading fixtures to it. The structure is an aws ec2 instance, on which runs a few docker container, including a django container. This the docker container in which I need to upload fixtures. This is all part of a ci/cd pipeline, with a postgres RDS database, nginx proxy, and the django container. I can scp the fixtures into the AWS EC2 instance. Then I can SSH into the EC2 instance, and from there log into the running container (using docker exec). That's all fine, but.... How can I access the fixtures that I uploaded to the ec2 instance (the docker host) from within the docker-container? Note: I'm aware I could commit the fixtures to git, then they would find their way into the docker image and be readily available there. I possible I'd rather scp them directly to ec2 & manage them in command lines (because small changes might be needed to the fixtures, which then means I have to run the whole pipeline and wait a few minutes each time...) -

Optimizing queries with Django ORM
I am using debug-toolbar to see the number of overall queries. The problem is that when I reload the page, I see different number of overall queries, given the same code and very short period of page reload intervals. I understand this is somehow related to caching. The question is, is there any shortcut to make Django at least in the debug mode always run all the queries so that I can see the real impact of my changes in the code ? -
Django: Apply filter for EACH element in Array-Field possible?
Hello Django community! I would like to filter my database using a contained_by operation on each element in a Array/JSONB field. Example: Instance has arrayfield: [[A, B],[C, D, E]] I would like to apply following filter to find this instance (written like python in-line loop): .filter(array_element contained by [A, B, C, D, E] for array_element in array) Because the arrayfield can have variable length I cannot index each contains operation explicitly. Is there a way in Django to do something like this? Thank you for you help! -

How to get Django custom form validator to work?
I'm working on a custom valdator for my Django forms. Inexplicably, I can't get the result I want. Here is my code from django import forms from django.core import validators from django.core.exceptions import ValidationError from .models import Vote from django.core.validators import MaxValueValidator, MinValueValidator def use_one(value): if value != 1: raise forms.ValidationError("Value is not 1!") class MyForm(forms.Form): main_form = forms.IntegerField(validators = [use_one], label= 'Main', required = False, widget = forms.NumberInput( attrs={'id': 'mainInput', 'name': 'main, 'href': '#', 'value': '', 'class': "form-control"})) Any thoughts? views.py form = MyForm() main_result = request.GET.get(main_form) form.fields['main_form_result'].initial = main_result context = {form: form}
