Django - How to process JSON response from TwelveData API in Template?
In a hobby project, I am using TwelveData API to receive Time Series Data. I am using JSON format response and able to check each data (example: open, close, high, and etc.) from Python side, but the problem arise when I am trying to show those data in Django Template page using the for loop. The JSON response is similar to below image: When I write the following for loop in the template: {%for r in result %} {{r}} {%endfor %} It prints GOOGL, AAPL, AMZN, and TSLA <-- which is pretty good. Now when I write another for loop like: {%for r in result %} {%for k in result.r %} {{k}} {%endfor %} {%endfor %} It prints nothing except blank page. So I rewrite the main for loop as follows: {%for r,v in result %} {{v}} {%endfor %} It prints ValueError: Need 2 values to unpack in for loop; got 5. Does anyone help me to identify how can I run the loop accurately so that I can get/print (maybe inside a table tag) the JSON response data as follows: open, close, high, and etc. Thanks -
Django template access dictionary key
Currently I am passing a dictionary with multiple keys from my views to django template, and the first key contains a list with all the wanted keys, and I want to have a nested loop to loop inside the first key so I can access inside the wanted keys. dict = { "list1" = ["name1", "name5"] "name1" = [] "name2" = [] "name3" = [] "name5" = [] } In this case, I only want to access dict['name1'] and dict['name5'], in Python I can do something like: for name in dict['list1']: for l in dict[name]: do things I want to know if I can do the same with django template inside html file -
django rest framework - how to log a slow API
django - 2.2.12 nginx - 1.14.0 (Ubuntu) uWSGI - 2.0.18 (64bit) My Django is slowing down during busy times. I want to find the cause. I found drf-api-tracking which can take slow log but I couldn't use it because I am using GenericViewSet. Are there any similar libraries or performance debugging methods? It is fast when I test and when there are few people. So it is difficult to debug. When there are the most people, the django server's cpu uses 45% and the AWS RDS cpu uses about 50%. I don't think it's a computer resource problem. So I want to log a slow API. How is it best to do it? Or is there a better way to debug? -

Django - "This Field is Required" error on Password field
On my django website, I'm unable to submit my form.

I have to models class Field(models.Model): name = models.CharField(max_length=255) user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE ) class Foo(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE ) title = models.CharField(max_length=255) fields = models.ManyToManyField('Field') def __str__(self): fields = [field.name for field in self.field.all()] return f'Title: {self.title} Field: {fields}' Now, I see the Foo as ['Title foo with field: [baz, bar]] Now.. I am trying to do this fields = set(Fields.objects.name) for field in fields: filtered_foo = Foo.objects.filter(fields__in =[field] But # print(filtered_foo) returns None My question is.. how do I filter a model based on another model which is manytomany relationship. -

Django Rest Framework - How to use "UniqueTogetherValidator" if one of the fields is provided as a URL variable
Hello I have a model with a unique_together constraint but the serializer cant validate it because one of the fields is being passed as a variable in the URL: How can I access the url variable int:pk inside the serializer for the "UniqueTogetherValidator" to work properly. My model: class Review(models.Model): user = models.ForeignKey(CustomUser, related_name='recipe_reviews', on_delete=models.SET_NULL, null=True) post = models.ForeignKey(Post, related_name='reviews', on_delete=models.CASCADE) rating = models.IntegerField() comment = models.TextField(blank=True, null=True) class Meta: unique_together = ['user', 'post'] My url looks like this: path('posts/<int:pk>/reviews/create/', ReviewCreateView.as_view()), My view: class ReviewCreateView(CreateAPIView): permission_classes = [IsAuthenticated] serializer_class = ReviewCreateSerializer def perform_create(self, serializer): # Grab post using URL Variable (pk) and save the review post = get_object_or_404(Post, id=self.kwargs['pk']) serializer.save(post=post) And my serializer: class ReviewCreateSerializer(serializers.ModelSerializer): user = serializers.HiddenField(default=serializers.CurrentUserDefault()) class Meta: model = Review fields = ['user', 'post', 'rating', 'comment'] validators = [ serializers.UniqueTogetherValidator( queryset=Review.objects.all(), fields=['user', 'post'] ) ] Since I'm not passing the post ID in the body of the request, I get the following error: { "post": [ "This field is required." ] } Is there any way of creating my own field that grabs the information from the URL variable? (similarly how the HiddenField is grabbing the CurrentUser automatically) I would really appreciate the help. Thanks! -

How to pass a function name as a parameter for dynamic url?

python-social-auth: Unable to keep logged in newly registered user after setting password
I am certain the problem derives from this statement: user.set_password(local_password) because when I omit it the pipeline ends with the user logged in as expected. Now, as others have pointed out, after using the set_password method django automatically finishes the session so to avoid that we may use update_session_auth_hash (request, user). The problem is that this does not work in the pipeline. I've also tried adding instead: user = authenticate(username=user, password=local_password) login(request, user) This also does not work. I also checked via print statements whether the user is authenticated, it happens to be in all 3 steps that I checked. Lastly, I also tried creating a new pipeline method and calling it afterwards. This one also did not work. @partial def login_users(strategy, request, user, *args, **kwargs): user = authenticate(username=user, password=strategy.session_get('local_password', None)) print(user.is_authenticated) request = strategy.request login(request, user) messages.success(request, "Welcome, you have successfully signed up") return In summary, and to avoid overflowing with data here, everything works as expected, but as soon as I save the password via user.set_password(local_password), the user is logged out and needs to click again on Linkedin to sign in. Otherwise, the behavior would be as expected, i.e. the data collected is saved and the home page … -

how to show thumbnail images from a local url stored in session system in Django?
Django 3 + sorl-thumbnail 12.7.0 Hello! I'm using the session system to store various items like this: request.session['cart'][1] request.session['cart'][2] ... request.session['cart'][n] In every session unit i want to store a product.image.url and other fields of the product: request.session.setdefault('cart', {})[str(request.session['counter'])] = { 'producto': p.pk, 'talla': talla, 'cantidad': cantidad, 'producto_abstracto': p.producto_abstracto.pk, 'imagen': p.imagen_1.url, 'nombre': p.producto_abstracto.nombre_producto, 'marca': p.producto_abstracto.marca.marca, 'precio_venta':p.producto_abstracto.precio_venta, 'nombre_color':p.color_principal_id.nombre, 'color': p.color_principal_id.codigo, } (I can't use pickleserializer to store in session the complete object Product for security concerns). Then I want to show in a view the product.image as a thumbnail but here is the problem. It seems that sorl-thumbnail just work with image Objects but i just have the url. Then in template i try this: {% load thumbnail %} {% thumbnail '{{item.imagen}}' '300x300' as im %} <img class="im" style="width:100%;" src='{{ im.url }}'></img> {% endthumbnail %} As a result i have a 404 not found image with a route in cache like this: media/cache/31/a0/31a02cc7b19899a208a972a08e17fe12.jpg to a file that was not created. As a comment when i use thumnail with classic django objects and images stored it works so i think it is not a problem about media and static routes or memcached.

Django admin GenericForeignKey object_id lookup
I'm looking for great way of selecting object of selected content_type (component_type). Django serves the raw id field where the user can input an integer. Is there a way to make it look more like the django grappelli solution? Like an 3rd part app to install which modifies admin template and adds ONLY this one feature instead of full django admin template? Or there is a good-looking template which has this option (because grappelli looks so bad). Thanks in advance
