Strange generation of arrays using numpy
I faced such a problem that with one algorithm different arrays are generated for me. Why is this happening to me? def formation(self): tickets = 0.00 new_tickets = 0.00 chanse = {} for item in items: new_tickets = tickets + item.item.quality.chance print(tickets,new_tickets) chanse[item.item.name] = numpy.arange(tickets,new_tickets,0.01) tickets = new_tickets return tickets,chanse And I get a result like this: 0.0 70.0 70.0 145.0 [0.000e+00 1.000e-02 2.000e-02 ... 6.997e+01 6.998e+01 6.999e+01] [ 70. 70.01 70.02 ... 144.97 144.98 144.99] -

Include foreign key in saving Django-Rest-Framework serializer
I am creating an API with Django Rest Framework. You can give a term to the api, it looks up data on a third party API and then everything should be stored to the database. All is handled in user scope and I have two tables, one with the search term and the ID of the user and another with the data received, which has the search_id as a foreing key. I now want that if you send a term to the API everything is stored and you get the search back, with ID and all dates. so far so good. I am now stuck, where I need to save the third party data to the database. The serializer demands the model object at saving and not the serializer from the user input. I tried around, but can't figure out, what I am doing wrong: models.py: class Search(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE,) term = models.CharField(max_length=200) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) def __str__(self): return self.term class foundTables(models.Model): search = models.ForeignKey(Search, related_name='search', on_delete=models.CASCADE) code = models.CharField(max_length=200) content = models.CharField(max_length=1000) time = models.CharField(max_length=200, blank=True, default='') created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) def __str__(self): return self.content serializers.py class SearchSerializer(serializers.ModelSerializer): class Meta: model = … -

formset factory with initial values or null
My models.py is rather simple: class Person(models.Model): name = models.CharField(max_length=254) class Question(models.Model): question_text = models.CharField(max_length=254) class Answer(models.Model): person = models.ForeignKey(Person, on_delete=models.RESTRICT) question = models.ForeignKey(Question, on_delete=models.RESTRICT) answer_text = models.CharField(max_length =254) And now I want to create form, where user can enter answers for all questions. And the same form would be for editing it... (formset_factory looks properly) But there's a problem.... The user can answer none, all or some questions (I want to add questions after answering it, then user enters form, add some answers, maybe change already answered) So I be stacked if FormFactory should produce Question or Answer form. And how to show all even null answers? -
How to set default and auto_now value for django datetime model field
I want to set a default DateTime for my Django model that will be used in querying data from google fit api. Since this field will be empty in the beginning, the default value will allow for the first query and the auto_now will keep updating as more queries are made. Django seems not to allow both auto_now and default as arguments. Could anyone please assist with a workaround I could use to achieve this? models.py class GoogleStep(models.Model): user = models.OneToOneField(User, related_name='googlestep', on_delete=models.CASCADE) starttime = models.DateField(null=False) endtime = models.DateField(null=False) steps = models.IntegerField(null=False) last_sync = models.DateTimeField(auto_now=True, null=False) class Meta: ordering = ('-starttime',) -

Django Passwords don't match after changing hasher, can't log in
i need to store my passwords in plain text in database(it is just django practise project) that's why i added a password hasher: lass PlainTextPassword(BasePasswordHasher): algorithm = "plain" def salt(self): return '' def encode(self, password, salt): assert salt == '' return password def verify(self, password, encoded): return password == encoded def safe_summary(self, encoded): return OrderedDict([ (_('algorithm'), self.algorithm), (_('hash'), encoded), ]) It works fine. But the problem is that i can't log in with these passwords, my theory is that django passes already hashed password to verification and that's why passwords dont match. I'm using allauth lib. Anyone have a solution? -

Playback state control of spotify web player sdk using spotify api
I am creating a webapp using django and react in which multiple user can control playback of a spotify player (play/pause, skip). This is useful in case of a house party or something where people are listening to a common device . I am thinking if i can integrate the spotify web player sdk and all users can listen to synced playback and control at the sametime remotely. I understand single spotify account needs to register that webapp to be used as device. My question is if can i control the state of playback if the page is opened by multiple users so that they listen to a song synchronously. -

Python crash course chapter 18. No learning_log directory is created
I'm doing exercises in the 'Python Crash Course' book in Chapter 18. I can't create the learning_log directory and manage.py, init.py, settings.py, urls.py, wsgi.py files. I made the creation of a virtual environment with the command: python -m venv ll_env I am using Windows so I used the command to activate the virtual environment: ll_env\Scripts\activate The environment has been activated because the name (ll_env) is displayed before the prompt. Then I installed the Django framework with the command: pip install django Installed successfully.But when I used the command: django-admin.py startproject learning_log . Unfortunately, the learning_log directory and the previously mentioned files are not created. I installed django version 3.1.4 and the book is version 2.2. Is there a problem here? Is there any other command to create this directory and files? Let me add that I was doing it all in the PyCharm terminal. -

Django DB cyclic model prevention Queryset
I am working on a project where I need have cyclic entries. Think, a recipe might have a sub recipe and that might have a sub recipe. The issue is one of those sub recipes might have its parents' parent as a child. So I am trying to prevent this or at least not wanting to have to proved the user with an option to select that item. To do this. I wanted to check on the server side if there is cycle. A classic loop detection. So I was going to either implement BFS or DFS, possible DFS to minimize the memory usage and check each child and their child and so forth until I visit all nodes and keep a visited dict to keep the ids of all the models entries I see. The issue is queryset is not providing some of the basic functions to do pop and push. I can convert the query set to list but that could be expensive and run out of memory. It is unlikely to have 100000 depth recipe but in theory it can happen. Is there an alternative to this? I was thinking maybe pass the visited list to filter … -
How many Django models is appropriate?
I'm making a Django project from a pre-existing epidemiological Excel model and I'm not familiar with how best to make use of Django models. The examples in the tutorial seem to fit 'just right' (e.g. one object is obviously the parent of another), and my data does not. My data consists of the following: A country, which has a name, a population of males and a population of females. However the population depends on the year (2019 to 2030). A cancer, which has a type (e.g. Breast cancer), a set of stages (e.g. Stage IV breast cancer). Cancer types interact with countries. E.g. the likelihood of dying from Stage III lung cancer is different in Australia than Uganda. This data currently lives in a bunch of json files, one which has the population per year of countries, one which has the proportion of people in an age group for a country, one which has the likelihood of dying from a cancer etc. I created these json files by exporting them from pandas dataframes, which we took from the lookup tables in Excel. I presume I could import each of these json files as its own model, but I get the … -
