Pass a curly braced data in Ajax in Django
In my Django project the user can add some saved products into a database. I have a view where the saved products are displayed. The user can then delete them if he wants to. To do so I am trying to implement an AJAX call. My HTML: <div class="col-md-1 my-auto mx-auto"> <form id="form_id" method='post'>{% csrf_token %} <button type="submit"><i class='fas fa-trash'></i></button> </form> </div> My AJAX: $("#form_id").on('submit', function(event) { event.preventDefault(); var product_id ='{{ saved.original_product.id }}'; console.log(product_id); var url = '/register/delete/'; $.ajax({ url: url, type: "POST", data:{ 'product_id': product_id, 'csrfmiddlewaretoken': $('input[name=csrfmiddlewaretoken]').val() }, datatype:'json', success: function(data) { if (data['success']) console.log(product_id) } }); }); And my view.py: def delete(request): data = {'success': False} if request.method=='POST': product_id = request.POST.get('product_id') print (product_id) data['success'] = True return JsonResponse(data) My view is not doing much for now but I am a learning Ajax for now and I do it one step at a time. What I want now is my print() and console.log() to display the value of {{ saved.original_product.id }} because for now then don't display it's value but {{ saved.original_product.id }} literal. I think the problem comes from my HTML. How can I pass the curly braced value into AJAX? -

Django request.FILES gets name, filename but not file (blob)
I'm trying to send an audiofile via a POST request to the server (aws, ec2) and I'm using Django, but my request.FILES doesn't receive the blob file, but it DOES receive the key and the filename. How can I get the file? Main.js: var fd = new FormData(); fd.append('text', speech); fd.append('audio', blob, 'test.wav'); $.ajax({ type: 'POST', enctype: 'multipart/form-data', url: url, data: fd, processData: false, contentType: false, success: function(response) { console.log(response); } }) speech is String, blob in console is Blob {size: 221228, type: "audio/wav"}, so it does exist. Views.py: def get_blob(request): thislist = [] for key in request.POST: thislist.append(request.POST.get(key)) for key in request.FILES: thislist.append(request.FILES.get(key).name) json_stuff = json.dumps({"check": thislist}) return HttpResponse(json_stuff, content_type="application/json") I've tried with and without enctype, doesn't make a difference. I've tried setting contentType to multipart/form-data, doesn't make a difference. The formdata seems to be sent correctly, because I can get the speech correctly (request.POST). And I can get the key from request.FILES ('audio'), and get the filename ('test.wav'). If I try request.FILES['audio'].read(), it says MultiValueDictError. If I try request.FILES.get('audio').read() it says AttributeError, 'NoneType' object has no attribute 'read'. Does anyone know what's going on and/or can help me with the problem? -
Use buttons (not radiobuttons) for Choicefield in Django?
I have a Django form: class Form0(forms.Form): # Do you agree to the terms? CHOICES = [ (1,'Yes'), (0, 'No')] response = forms.ChoiceField(widget=forms.RadioSelect,choices=CHOICES) It is being rendered in my HTML template. I have made a script to enable submitting the form when clicking on a radio button which works perfectly: <form method="POST"> {{ form.as_table }} {% csrf_token %} <script> $("input[type=radio]").on("change", function () { $(this).closest("form").submit(); }); </script> </form> It looks like this: The problem Is it possible to display the 'Yes' and 'No' radioselect as normal buttons? E.g. using bootstrap buttons like: <button class="btn btn-primary" type="submit">Yes</button> <button class="btn btn-primary" type="submit">No</button> -
How do you add form-#-DELETE to form in Django using Javascript?
I'm trying to delete a form from a formset using javascript. In the Django docs it states: ... if you are using JavaScript to allow deletion of existing objects, then you need to ensure the ones being removed are properly marked for deletion by including form-#-DELETE in the POST data. How do I interact with the POST data using javascript? They even provide an example of what they're looking for: data = { 'form-TOTAL_FORMS': '3', 'form-INITIAL_FORMS': '2', 'form-MAX_NUM_FORMS': '', 'form-0-title': 'Article #1', 'form-0-pub_date': '2008-05-10', 'form-0-DELETE': 'on', 'form-1-title': 'Article #2', 'form-1-pub_date': '2008-05-11', 'form-1-DELETE': '', 'form-2-title': '', 'form-2-pub_date': '', 'form-2-DELETE': '', } So I want to somehow add something like 'form-0-DELETE': 'on', to the POST data. But this seems to be Python code. I want to manipulate it in the client with js. -
Extending IntegrityError class in Django
I'm trying to handle this error django.db.utils.IntegrityError: duplicate key value.... The problem is I don't want to catch all the integrity errors, just the one that has the message "duplicate key value" in it. For example, this is what I'm doing: try: activity.save() except IntegrityError as e: # if the error is not a key duplication one then throw again if 'duplicate key value' not in e.args[0]: raise e My question is if there is a way to extend the IntegrityError class so that the child class can check the error message of the IntegrityError class? -
Unable to successfully use axios with React Native to make a request (IOS)

Change query string to allow for multiple values
I have an issue with my query string, the problem is when multiple values are selected my Django search breaks. I get this in the URL ?Query=value1&Query=Value2. In this scenario, it's only the last value that is searched. What I want to happen is that both values are searched (with the equivalent of an AND operator in-between). This is the desired result ?Query=value1+Value2. I've added my search form that uses Select2 and my Django search view below. If you need anything else let me now. Any help would be much appreciated.

How can I enable my html page to check the user with two boolean field value and display their data using the "if" statement?

How can I write a Django custom save method that will get or create a foreign key before saving
I have following Django models for City and State set up like this: class State(models.Model): name = models.CharField(max_length=55) abbreviation = models.CharField(max_length=2) class City(models.Model): name = models.CharField(max_length=55) state = models.ForeignKey( State, on_delete=models.CASCADE, null=True, blank=True ) I'm importing json company data that includes NAME, CITY, and STATE. It looks like this: {'NAME': 'Company Name', 'ADDRESS': '123 Main St.', 'CITY': 'Bethel', 'STATE': 'Connecticut'} I'm trying to set up a custom save method to my Company object that would get or create the necessary City object upon creating or updating the company. Creation of a City object will, in turn, require the getting or creating of a State object. class Company(models.Model): name = models.CharField(max_length=55) address1 = models.CharField(max_length=200, blank=True) address2 = models.CharField(max_length=200, blank=True) city = models.ForeignKey( City, on_delete=models.CASCADE, null=True, blank=True ) zipcode = models.CharField(max_length=20, blank=True) def save(self, *args, **kwargs): self.city, created = City.objects.get_or_create(name=city) super(Company, self).save(*args, **kwargs) Since the state field in City is not required, I'm starting with just trying to create the city. But Django is returning this error: Cannot assign "'Bethel'": "Company.city" must be a "City" instance. -
Django DRF with React: How to obtain CSRF cookie?
I have a React frontend running at frontend.example.com and a Django backend with DRF running at backend.example.com. I am using Django Session Authentication and I want to properly implement CSRF protection. Taking the React login page frontend.example.com/login as an example. It's the first time for a user to visit the page. There is a form with a user and password and on submit a new POST request is created to the Django backend. To the best of my knowledge, the CSRF token cookie should already be included in this request, right? How to obtain that CSRF token from the Django backend? I am thinking of doing a GET request to the Django backend on loading the login-page to obtain that CSRF token cookie. Is that the way to do it or is there any other best practice? -
Why am I managing two versions of a Django static file?
I'm still confused by some Django static file management and have a suspicion I'm doing something wrong/stupid. I have a core css file - /app/static/base.css But for some reason, cannot recall why, I also have - /static/css/base.css Here's everything in my settings file that I think relates to static files: PROJECT_DIR = os.path.dirname(os.path.abspath(__file__)) STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' STATICFILES_DIRS = ( BASE_DIR+'/other_app_1/static/', BASE_DIR+'/other_app_2/static/', BASE_DIR+'/app/static/', ) STATICFILES_LOCATION = 'static' # uncomment and run collect static before pushing to live - python manage.py collectstatic # remember to change back for when you continue to develop #STATICFILES_STORAGE = 'custom_storages.StaticStorage' I've pasted that as it might reveal why I originally started doing this, there has to be a reason. Am I correct in thinking I can stop updating /static/css/base.css and simply use the other one? I can't recall why I started, but I'm sorry to say that I still find Django static file management very confusing. -

first this is urls.py for django project here all things are fine from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), ] but when i add my app url from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('movie/', include('movie.urls')), ] it says File "/storage/emulated/0/netflix/movie/urls.py", line 5 urlpatterns = [ ^ IndentationError: unexpected indent
