django python def choices/documentation
In Django Python, where can I find documentation about all available def? For example, I have def clean(self): and def __init__(self, *args, **kwargs): I want to know what my possible options are for def. For example, I want to force a decimal field to return a string. Which def can I override that would allow me to cast a return value? Is there some documentation out there that someone could point me to on this subject? -

Social authentication for Google failing with Vue.js and django-rest-auth
I am following a blog that shows us how we can use vue-authenticate with django restframework for social authentication. This is the blog: https://medium.com/@dobrotek6/drfsamv-django-rest-framework-social-auth-mongo-vuejs-part-1-c5c907dd7b69 However, the blog uses some the social-auth framework which I am not using. I'm using the django-rest-auth package. I tried to set it up accordingly but I am running into some issues. redirectUri: 'http://localhost:8080/', url: 'http://localhost:8000/rest-auth/google/', The above code shows the links I'm placing in the provider settings according to the vue-authenticate documentation this.$auth.authenticate('google', {provider: "google- oauth2"}).then(function (response) The above code shows the authentication method according to the documentation in vue-authenticate that I copied from the blog. This is where I get the error that says authentication failed. What exactly is it that I'm doing wrong? I can't seem to identify the issue. -
CORS policy issue on ajax img load (django)
on ajax load, image_url contains https link. So no problem with https access. but when I access the same page on http, I get this toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.

django.apps apps.getModel('app_name.model_name') finds no models
I'm new to Django and using Django 2.1.7. Up to today, I have had a (simple) working system. Then I needed to introduce a circular dependency between two of my model classes, which creates circular imports and causes problems, etc... I have read that since Django 1.7 the proper way to import a circular dependency between models is: from django.apps import apps from django.db import models Model2 = apps.get_model('my_app.Model2') class Model1(models.Model): # use Model2 where needed However, I always see the error: LookupError: App 'my_app' doesn't have a 'Model2' model. Note that both Model1 and Model2 are in the same app, so I have tried calling apps.get_model() both with and without the app prefix. If I just remove the circular dependency (ie: Model1 no longer references Model2), both models works just fine in the system independently. DB queries work, makemigrations works, migrate works, etc... And to be sure, in my settings.py file: I have 'my_app' declared at the top of the INSTALLED_APPS array. I also tried moving it to the bottom. What gives? Seems so simple I don't know what I could be missing. Do I need to register my models somewhere else explicitly? Any help would be much appreciated! -

how to reload a segment of webpage in django?
In django, I am trying to make buttons that change one segment of the webpage by loading html file. The html file shows map and statistics and stuff so they have to be separate. My approach was to use ajax call and in the view, return the html file. <script type="text/javascript" > function mapcall (office, year){ console.log(office, year, "clicked") $.ajax ({ method : "GET", url: '/map/', // % url "map" % end point data: { office_called: office, year_called: year, }, success: function (map){ console.log("map is here ", map) $("#maparea").load($( "{% static 'my_html_return' %}" ))}, error: function (error_data){ alert("data error, sorry") } }) } </script> <div id="maparea"> {% if map_return %} {% with map_template=map_return|stringformat:"s"|add:".html" %} {% include "mypath/"|add:map_template %} {% endwith %} {% endif %} </div> This is my view.py def get_map (request, *args, **kwargs): year = request.GET.get("year_called") office = request.GET.get("office_called") map_return = "map"+str(year)+office return render(request, "mypath/home.html", {"title": "Home", "map_return":map_return}) I don't know how to make this work. Any suggestion is appreciated. -
