Django JSONField not receiving cleaned data
I have a very simple model which contains a JSONField: class Thing(models.Model): title = models.CharField(max_length=1024) text = JSONField(default=dict) I've created a custom widget that allows for the input of key-value pairs: class JsonWidget(forms.widgets.Widget): template_name = 'json_widget.html' def get_context(self, name, value, attrs): context = super().get_context(name, value, attrs) data = json.loads(value) if not data: data = JSON_DEFAULT context['data'] = data.items() return context def value_from_datadict(self, data, files, name): keys = data.getlist('json-key') values = data.getlist('json-value') json_data = {k: v for k, v in zip(keys, values)} return json_data I coerce the dict returned by the widget into a string in the field's clean function on the form: class ThingForm(forms.ModelForm): class Meta: model = Thing fields = ['title', 'text'] widgets = { 'text': JsonWidget(), } def clean_text(self): text = self.cleaned_data.get('text') return json.dumps(text) I've inspected the output of JsonWidget.value_from_datadict (dict) and ThingForm.clean_text (str) are the expected types. But when the object goes to save it throws an exception: TypeError: the JSON object must be str, bytes or bytearray, not 'dict' This is my first time building a custom widget for Django, is there something obvious I've missed here?

How to write test for django inbuilt login form by using assertFormError
I have to write unit tests for user login in my app. I have used django.contrib.auth.views for login. And i have to use assertFormError for testing error message in form.

How to save records and get records on behalf of another user
I'm working on a Django 1.5 Project. The application contains the user hierarchy of Owner Admin Viewer Owner owns all the data in the database. Admin users are created by the owner and have different login credentials. Can add/edit/delete data under Owner. Viewer users are created by the owner and have different login credentials. Can view data created under the Owner. Users model have a field is_shared (boolean) to identify main user and shared user and access_level is mapped in another model MultiUser. I have thought of to implement it in the way Update all viewsets and put check in get_queryset. where first check will be made if user has is_shared=True then check in MultiUser model, get the user from MultiUser and then filter records on behalf of the user. But this will require changes throughout the application viewsets. Is there a way to do this without making changes to the whole application. May be middleware. -
Cant see SQL queries with multiple database landscape
Django 2.1.7, MySQL. DATABASES config is like: DATABASES = { 'default': {}, 'auth_db': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'auth', ... }, 'db1': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'db1', ... }, 'db2': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'd2', ... } } I have various issues with viewing raw SQL queries: 1) Cant print the query of particular queriset: qs = Model.objects.using("db2").filter(...) print(qs.query) This code drops ImproperlyConfigured because it doesnt respect the .using("db2") and somewhy check the default db which is empty (Empty default_db is quite okay as said in django docs) 2) When in runtime i open a shell to monitor queries: from django.db import connections print(connections["db1"].queries) i just see this: [{'sql': 'None', 'time': '0.001'}, {'sql': 'None', 'time': '0.000'}, {'sql': 'None', 'time': '0.008'}] debug=True is set like said in docs. Anyone has an experience with this kind of issues woth multiple db? -
What does choice mean in "for choice in question.choice_set.all" from the Django poll tutorial?
I'm new to Django and am working through the first poll tutorial. I'm having trouble understanding the use of the word "choice" in a for loop within the tutorial. I've read other questions related to this part of the tutorial, but most dealt with choice_set.all {% for choice in question.choice_set.all %} <li>{{ choice.choice_text }}</li> {% endfor %} My question is related to the initial use of the word choice in the for statement... for "choice" in. It appears to be referencing the whole Choice model which I don't quite understand. It seems like it would make more sense to say "for choice.choice_text in" while looping through checking for choice_text matches against values in question.choice_set.all. The Choice model contains choice_text, question, and votes at this point of the tutorial. Can someone help me understand what the first mention of choice refers to in the for loop? -

nginx host not found in upstream in dockerized nginx
I have a set up and running nginx container and django app container on my server. I wanted to bulid another container that holds another django app but on another python version. So I did. But then when I tried to configure proxy_pass to my new container nginx keeps restartings with error [emerg] host not found in upstream "zen_bhaskara" in /etc/nginx/nginx.conf:91 Thing is I already had the same problem when I was setting up first and now running django app. I solved it by creating new network and adding two containers in it and then nginx could resolve container name. But same trick didn't work with this new container and I spend hours already without any success of sovling it. Here's a config for my first app: server { server_name some.server.name; listen 80; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; auth_basic "Restricted"; auth_basic_user_file /etc/nginx/conf.d/pass.htpasswd; location / { client_max_body_size 500m; proxy_pass http://django_app_1; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; } Then I tried to do the same for new app: server { listen 80; resolver 127.0.0.11; server_name another.server.name; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://djangoapp2:80; } } And here's my Dockerfile for a new app: FROM … -
jQuery not loading in Django admin homepage/dashboard, login and logout pages
I need to load a js file throught all django admin pages. Hence I copied the base.html file located in django/contrib/admin/templates/admin/ and added it to my templates folder under templates/admin/base.html. Added the js file under app_static/admin/js/ (location to my static files). Next, I included the <script> tags inside the base.html under the {% block extrahead %} tags. When I open the change_list and change_form pages, the js fires correctly. It does not fire in the homepage/dashboard, login and logout pages. Returns an error stating Uncaught ReferenceError: django is not defined. An error usually thrown when jQuery has not been initialized. session_expiry.js (function($){ $(function() { console.log('js has been called'); }); })(django.jQuery); Could anyone point out what I might be missing. -

django-rest-auth with Google: How to post access token properly
I'm really new to using retrofit2. I'm trying to send access token to the backend from mobile app and authenticate the user via Google but I can not do it properly. The backend returns 400. My code is like this. views.py from allauth.socialaccount.providers.google.views import GoogleOAuth2Adapter from rest_auth.registration.views import SocialLoginView class GoogleLogin(SocialLoginView): adapter_class = GoogleOAuth2Adapter urls.py path('rest-auth/google/', GoogleLogin.as_view(), name='google_login'), And my Java code (I'm using retrofit2) public interface ApiService { // login @POST("/rest-auth/google/") Call<Account> login(@Header("access_token") String accessToken); MainActivity.java private void login() { ApiService service = ApiClient.getService(); service.login(mAuthToken).enqueue(new Callback<Account>() { @Override public void onResponse(Call<Account> call, Response<Account> response) { if (!response.isSuccessful()) { Toast.makeText(MainActivity.this, "Code:" + response.code(), Toast.LENGTH_LONG).show(); return; } Toast.makeText(MainActivity.this, "Success!", Toast.LENGTH_LONG).show(); } @Override public void onFailure(Call<Account> call, Throwable t) { mTextViewResult.setText(t.getMessage()); } }); } mAuthToken is access token. I think I'm wrong with the way to pass the access token to backend. What am I wrong with this?
