Django ajax GET 403 (Forbidden)
I have a page of articles and a Load More button with ajax call in my Django app. The problem is that the Load More button works just when the user logged in to the site. If an anonymous user clicks on the button, it doesn't work, and sees the error below in the chrome console: In the network tab in chrome console I see this error: But I don't want to identify the user who clicked the button and want to show more posts to everyone! The ajax call is : // Load more posts in the main page $('.load-more').click(function () { var card_count = $(".card-count").length; $.ajax({ url: 'load-more', method: 'GET', data: { "card_count": card_count, }, success: function (data) { // Append more articles to the article List }, error: function (data) { } }); }); I do some search and tried some ways to pass the csrf_token or skip it: This link & This link But still stuck on this. How can I get rid of this error? Thanks for your help. -
Django CSRF cookie sending images with axios client
Good day. I need to send an image by the post method of a client with axios to a Django server but I get the following message on the server. Forbidden (CSRF cookie not set.): And the client gives me the following answer xhr.js:177 POST http://127.0.0.1:8000/xxxx/ 403 (Forbidden) How is it possible to solve this problem? It is possible to disable the CSRF cookie= This is the client code: var formData = new FormData(); formData.append("imagen", await fetch(`${filepath}`).then((e) => { return e.blob() }) .then((blob) => { let b: any = blob b.lastModifiedDate = new Date() b.name = '' return b as File }) ); const axios = require('axios'); axios({ url:url, method:'POST', data:formData }).then(function(res: any){ console.log(res) }).catch((error: any) =>{ console.log(error) //Network error comes in }); And this is the server view function (It just check the info to debug) def completeInfo (request): print(request) return HttpResponse("Bad Response") -

Django Rest Framework: Send full foreign key objects in GET response but accept only foreign ids in POST payload, without two serializers?
Say I've two models: class Singer((models.Model): name = models.CharField(max_length=200) class Song(models.Model): title = models.CharField(max_length=200) singer = models.ForeignKey(Singer) And two serializers like: class SingerSerializer(serializers.ModelSerializer): class Meta: model = Singer fields = '__all__' class SongSerializer(serializers.ModelSerializer): singer = SingerSerializer() class Meta: model = Singer fields = '__all__' I've defined the serializers as above because I need the full foreign key object in the GET response for songs: { "singer": { "id": 1, "name": "foo" }, "id": 1, "title": "foo la la" } Is there a way to allow POST/PATCH payloads to only send in the id of the foreign object and not the entire object, without writing a different serializer? I'd like the PATCH payload to be so: { "singer": 1, "id": 1, "title": "foo la la" } -
