How to create a list of dictionaries from a dictionary with lists of different lengths
I want to create a list of dictionaries with the same index element from each list. I have a this dictionary: d = {'name': ['bob', 'john', 'harry', 'mary'], 'age': [13, 19, 23], 'height': [164, 188], 'job': ['programmer']} The desired output is: d2 = [{'name': 'bob', 'age': 13, 'height': 164, 'job': 'programmer'}, {'name': 'john', 'age': 19, 'height': 188}, {'name': 'harry', 'age': 23}, {'name': 'mary'}] I have tried something like this: d2 = [dict(zip(d, t)) for t in zip(*d.values())] But my output is: d2 = [{'name': 'bob', 'age': 13, 'height': 164, 'job': 'programmer'}] I think this is happening because the lists have different lengths -
What's an appropriate way to setup consumer driven contract testing for django api and react clients?
I just learned a new term called consumer driven contract testing. I was thinking maybe it can help me solve my problem with writing tests for a django api provider and react frontend architecture project. The frontend and the Django API backend are in separate repos and have their own unit tests. However, once in a while there will be error because the frontend is assuming some fields that are not returned by the Django service backend. I initially thought about writing end to end test, but they are slow to run and highly brittle. I found this consumer driven contract testing and it sounds like the right thing. But when i google around, i cannot find anything suitable. Even Pact seems to be solely for just converting the contract to consumer tests. What's a suitably easy way to have consumer driven contract testing for this scenario? -

How do i correctly implement web scrapping into my api
I'm making a django api that is able to return a definition of a word to a user this word is looked up by using a word=(put word here) url, this api scrapes dictionary.com to get the definition if it does not already exist inside my database, than adds it to my database if it exists on their site. i'm just trying to figure out how to actually structure it correctly instead of just throwing it into my view. I want to be able to return json to the end user with suggestions if a word is not found in the database or on their websites by scrapping their recommendations. I have tried returning json responses inside the view if a 404 error happens. Always throws a error i'm under the assumption my whole structure is wrong. def get_queryset(self): word = self.kwargs['word'] headers = {"User-Agent": "user agent stuff"} if not Word.objects.filter(word=word).exists(): page = requests.get(f"https://www.dictionary.com/browse/{word}?s=t", headers=headers) soup = BeautifulSoup(page.content, 'html.parser') try: output = soup.find("div",{"value": "1"}).get_text() test = Word(word=self.kwargs['word'].strip(), meaning=output) test.save() except: return return Word.objects.all() i expect the user to be able to get a definition if the word exists or if it doesn't to be able to return recommendations that i … -

Check Django migrations status programmatically
I need to run an initial migration for a Django project without allowing system checks (because the error will be resolved by creating the models) Right now, I'm using a custom command like so: class Command(BaseCommand): help = "Init project by launching initial migration without system checks" requires_system_checks = False def handle(self, *args, **options): management.call_command("migrate", "app", "0001_initial") This command is run by the script that bootstrap the environment (with docker-compose) It runs really well the first time, as no migrations have been executed. If I restart it however, this custom command forces the project to revert migrations back to 0001_initial. Is there a clean way to check programmatically if a migration has been executed ? I think I could get some values from the django_migrations table, but I'd rather use something cleaner if it exists. Thanks for your help! -

How to predict in multiple and simultanous Keras classifier sessions?
I know similar questions has been asked before and I have read all of them but none solved my problem. I have a Django project in which I am using CNNSequenceClassifier from sequence_classifiers which is a Keras model. The model files have been fit before and saved to particular destinations from which I again load them and predict what I want. clf = CNNSequenceClassifier(epochs=2) When I load the model I do this, due to the suggestions I found in searches, which is using the global model before loading the model, and then the other two lines: global clf clf = pickle.load(open(modelfilenameandpath, "rb")) global graph graph = tf.get_default_graph() and before predicting I use graph.as_default() with graph.as_default(): probs = clf.predict_proba(the_new_vecs) K.clear_session() I put K.clear_session() because I predict in a for loop and sometimes the next item of the for loop's prediction gets mixed up with the last one and raises tensorflow errors. But clearly K.clear_session() clears the session and makes it easy for the new item's prediction to work fine. The problem is in my views.py I have two functions which trigger prediction. And sometimes I need to use both simultanously. But since the probject is using Tensorflow Backend, only one session … -

How to do PUT request without primary key?
I'm creating a Like/Dislike api for a blog using DRF. I have Like table which contains "Post", "User" and "isLike" fields. Since Django can't have composite key, I'm using unique_together constraint for ("Post" and "User"). If a user likes a post, I create a entry in Like table. Now if a user wants to remove his like from the post or want to dislike the post, I need primary key of entry from Like table for these (PUT/DELETE) methods. Since I know "User" and "Post", and since both are unique, Can I perform (PUT/DELETE) methods with unique fields? Model class class LikeDislike(models.Model): """model for like counts""" post = models.ForeignKey(Post, on_delete=models.CASCADE) user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) isLike = models.BooleanField() class Meta: unique_together = (("post", "user"),) View for creating entry in Like table: class LikeDislikeCreateView(generics.CreateAPIView): queryset = models.LikeDislike.objects.all() serializer_class = serializers.LikeDislikeSerializer def perform_create(self, LikeDislikeSerializer): LikeDislikeSerializer.save(user=self.request.user) I can update a like/dislike using -> /like/primary-key/ but I want to do using "post" and "user" details. -

How to rename a model field from default Django model?
I would like to rename all the Groups field in Django admin as Roles field. But there are still some parts that didn't changed. I have successfully renamed Groups into Roles but then a field in the Users still has the name 'Groups' in it. I know it has something to do with the PermissionsMixin in django.contrib.auth.models which contains the ManyToManyField named groups that is being called in the UserAdmin. I would like to know how to rename this model field. This is the field that I want to rename. -

Django: How can I use templating to add a header to each HTML page, and only update one central file?
I have about 12 different HTML pages in my Django application. I am looking for a way to make my header in 1 template file, and then add that file to each HTML template that I need a header on. I tried following the template documentation from Django, but it wasn't concise enough for me. Would anyone be able to please break it down a little further for me? I am basically starting at square 1 with this... I was at a point where I was able to get a header to load, but no css was attached to it.
