I made a website using mezzanine-Django , and used conda env to contain it (I should have used virtual env). but the fabric file is tuned to only deploy virtual envs. What should I do to get my conda env up in the VPS , is there an easy way or should I be installing every packages inside manually? -
Dockerizing multi-node python django backend served by nginx
I am trying to dockerize a project that consists of multiple backend nodes that are served by an nginx server. Would I rather have an insance of nginx running in each docker container serving just that node or would I have a "central" NGINX server that serves all nodes. In case of having a central nginx server, how would it comminicate with the backend nodes. The backend is implemented in python django. If each container has its own nginx instance, the comminication between the web server and the python django application is straighforward. But how would I serve a python django application that lives in one container from an nginx server that lives in another? In case of having an instance of nginx in each container, how would that impact the overall performace of the system? -
Speed Jquery toggle function not taken into account
I'm working on a web app. I use : Last version of Django In a virtual environment for python I use the CDN of getbootstrap (https://getbootstrap.com/) I'm trying to toggle a DIV block when I click on another DIV. This my Jquery script : {% for s in salle %} $( ".{{ s.name }}" ).click(function(event) { var className = $(this).attr('class'); className = "." + className + '-content'; $(className).toggle('slow'); }); {% endfor %} I would like a slow effect. That's why I put a 'slow' speed inside of the toggle() Jquery function, but it is not considered. Would you have an idea of what I'm doing wrong ? Thanks a lot ! -
Django thinks I have an id field when I do not
I have created the following model: class World(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) name = models.CharField(max_length=200) setting = models.CharField(max_length=200) creation_date = models.DateTimeField('date created') when I run manage.py makemigrations I get the following error: You are trying to add a non-nullable field 'id' to world without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Quit, and let me add a default in models.py Why does Django think I have an id field, and how do I get rid of this error? -
Django problem "super() argument 1 must be type, not WSGIRequest" in Python 3
While to use class inheritance, Python 3 fails with "super() argument 1 must be type, not WSGIRequest". I'm on Django 2.1.4 and Python 3.7.0. I am trying to see if a user already submitted an file to be analyzed, if not, he is directed to the submission page. I've tried to do not use static methods, check if it's really Python 3 (because this problem is common on Python 2), on the super class I tried to inherit from "object" while also inheriting from "View" provided by Django (because this solves in Python 2 super() argument 1 must be type, not None). This is the super class, it inherits from the class provided by Django "View". class DatasetRequired(View): @staticmethod def get(request): <redirects the user> This is the base class class Estatisticas(DatasetRequired): @staticmethod def get(request): super(request) <do various other stuff> I'm expecting that the base class' get function while called will call the super class get function and check if the user already submitted the file. I get: "TypeError at /estatisticas super() argument 1 must be type, not WSGIRequest" -
Django test client ingnores "include" terms in django template
I have an issue with Django tests client. Let for the home path I have this template (home.html): <html> <body> {% include 'example.html' %} </body> </html> and in example.html I have error: <div> {% non_registered_tag arg1 arg2 %} </div> I wrote a test for accessibility to a Django URL. class HomePageAccess(TestCase): def test_home_page(self): client = Client() response = client.get(reverse_lazy('home')) self.assertEqual(response.status_code, 200) This code fails successfully if there be an error in home.html, But if there be an error in example.html which is included in home.html Test will pass even though we expect to fail because I included it in home.html and in the browser I encounter an error (status code 500) while this not happens in test client. Is it normal? I'm using Django 2.0.2. Any help will be appreciated -
Create a python function to return a session token and pass token to celery task (django)
I need to create a session token and use this token in a request to get data from the matchbook betting exchange api. The shared task below is on a celerybeat task running every two seconds getting pricing for events. This is the function I have below to get the pricing. The problem is if I login every time with mb.login() before I run the task I will get my ip blocked due to too many logins I need to create a session token and call it like mb.get_session_token.get_events I am using a prebuilt wrapper that's on github to interface with matchbook api. https://github.com/rozzac90/matchbook There is no documentation but there is some info in the docstrings that I'm having trouble understanding but I think there's a function for creating session tokens but I'm not sure how to use them. I would like to know how I can make a function that returns a session token and pass it to my function below. Also there's a keep alive function that is used to keep refreshing your connection. I'm not sure how it works but I think you need to ping that function every 6 hours. My function from matchbook.apiclient import APIClient … -

Can I have data from different fields of a model returned as separate HTML elements? (Django 2.1)
I am compiling a database of articles and have my model set up like this: class articles(models.Model): ArticleID = models.IntegerField(primary_key=True) Title = models.CharField(max_length=500) Author = models.CharField(max_length=200, null=True) Journal = models.CharField(max_length=500, null=True) Date = models.IntegerField(null=True) Issue = models.IntegerField(null=True) Link = models.URLField(max_length=800, null=True) Content = models.TextField() class Meta: db_table = 'TEST' def __str__(self): return f'{self.Title}, {self.Author}, {self.Journal},{self.Date}, {self.Issue}, {self.Content}' def get_absolute_url(self): return reverse('article-detail', args=[str(self.ArticleID)]) The idea is pretty simple. Each meta data type (i.e. title, author) is it's own field, and the actual content of the article is in the field Content. My view for this model: def article_detail(request, ArticleID): ArticleID = get_object_or_404(articles, ArticleID=ArticleID) context = {'ArticleID': ArticleID} return render(request, 'article_detail.html', context) The HTML template for the view: {% extends 'base.html' %} {% block content %} <div class="container"> {{ ArticleID }} </div> {% endblock %} The data displayed in on the HTML page is one big block of text in one single HTML element. How can I make it so that I can use CSS to target each individual field from the model? Must I make separate models for each field (and bound them with foreign keys)? -

I am writing an app that will visualize Strava (social site for athletes) user's activities in various ways. The user is required to authenticate with his Strava account, and then my app downloads his activity data from Strava API. As there will be no user accounts in my app - just the Strava authentication - I have decided to not use a database. Therefore, I would need to store the activity data in memory. The data would be quite big: for example, I have 800 activities on Strava, each being a longish JSON. Would storing the data in session like session['activities'] = some_downloaded_activities be suitable for this? I would then set up API endpoints that would query this session data, filter it as required by the front end of my application and return it. My other idea is to use a database only to store the JSON file, but delete the data immediately after the user session is done - but it seems like an overkill. Or is there a better approach?
