Django app with docker-compose keep the data in media volume
I'm using Django cookiecutter with docker and docker-compose. On production I'm using dj-static to serve my media files. Whenever I use 'docker-compose down' command everything that is in my media volume gets deleted. I think this is the expected outcome of that command but everything that is in 'postgreSQL' is kept. How can I do that with the 'media' volume? -

Django model save() - AttributeError: 'NoneType' object has no attribute 'append'
In my models.py I want to extend the Django User model by adding an email_list. from django.contrib.postgres.fields import ArrayField class User(AbstractUser): email_list = ArrayField(models.EmailField(max_length=100), null=True, blank=True) [...] This email_list has to have the user email as default value. I found that the best way to do this, is by overriding the save() method: def save(self, *args, **kwargs): self.email_list.append(self.email) super(User, self).save(*args, **kwargs) However, when I add a user I get the following error: AttributeError: 'NoneType' object has no attribute 'append' And the print(type(self.email_list)), returns <type 'NoneType'> What is wrong with the ArrayField? -
django recreate dropped table
I dropped a table manually cause while changing the model I made a very bad mistake. So anyway ... how can I recreate it ? I have tried : - Delete the migrate folder of that app - delete from django_migrations where app='main' - makemigrations main - migrate main But it stops at the first table. Which is there :-( and my Table message in that case is not recreated. In initial.py I have the correct entry for my table migrations.CreateModel( name='Message', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('created_at', models.DateTimeField(auto_now_add=True)), ('updated_at', models.DateTimeField(auto_now=True)), ('unread', models.BooleanField(default=True)), ('subject', models.CharField(max_length=120)), ('freetext', models.TextField(null=True)), ('from_user', models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, related_name='from_user', to=settings.AUTH_USER_MODEL)), ('to_user', models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, related_name='to_user', to=settings.AUTH_USER_MODEL)), ], ), Is there way to start this manually ? -

Django M2M field unit-tests not failing
I have a model Notification class Notification: reports = ManytoManyField() On my code I had this line: Notification.objects.create(reports=reports_list) The above throws a database constraint violation when run (relating to report fk), although, when executing the same code with unittests, there is no error. I even assert the result and it passes, e.g: notification = Notification.objects.create(reports=reports_list) ... notification.refresh_from_db() self.assertEqual(notification.reports.count(), 10) Is this the expected behaviour on this scenario ? -

Apache serving Django and Angular
I have a project with Angular frontend served by a Django Rest API. My project is in the following structure. example.com |- client (holds angular files) |- server (holds Django Rest Framework files) The angular app makes calls to drf through http: example.com/api/<params> I'm hosting on a Linode Ubunutu 17.04, using Apache and uWSGI. I can't seem to figure out the best way to serve both Angular and Django at the same time? I can easily host the Django Rest API with the WSGI config, but can't figure out how Apache knows to point to Angular for normal requests. What's wrong with the below solution or is there a better way? In /etc/apache2/sites-available/example.com <VirtualHost *:80> ServerName example.com ServerAlias www.example.com DocumentRoot /var/www/example.com/client/ </VirtualHost> <VirtualHost *:80> ServerName example.com/api ServerAlias www.example.com/api WSGIScriptAlias / var/www/example.com/index.wsgi DocumentRoot /var/www/example.com/server/ </VirtualHost> Any help would be greatly appreciated! -
Django - How to handle on the fly checkbox
I'm quite new to django, and i'm pretty much stuck on this problem. I'm creating a website who can handle lists of objects. Every detailview of a single object display all the list available for the customer (every list created by him or the other people working in the same company), checked if the object is in this list, unchecked if not. My problem is the following : I want that when the user press the submit button, my DB to be updated. If there is no change on the box, nothing happen on the DB If there is a change, of course, the DB is updated. But only on the items who's "state" as changed Here's my template: <form action="{% url 'forms:add-list' artpiece.id %}" method="post"> {% csrf_token %} {% for foo in list %} <input type="checkbox" name="listform" value="{{ foo.id }}" {% if artpiece.pk in foo.art_inlist %} checked {% endif %}> {{ foo }}<br> {% endfor %} <input type="submit"> </form> And my models : class ArtList(models.Model): name = models.CharField(max_length=250, blank=False) creator = models.ManyToManyField(User) art_ids = models.ManyToManyField(ArtPiece, related_name='artid') def __str__(self): return self.name def art_inlist(self): return self.art_ids.values_list('pk', flat=True) Is something like looping into every list and checking for the ID is present … -
How to respond to django.test.Client using the test database
I have a django settings.py file with one configured database, leading to two mysql databases, let's call them dbname and test_dbname. When running a command like python manage.py test ..., an object selection like MyClass.objects.all() will select the objects from test_dbname, so far so good. On the other hand, if I test the generation of an html page using client = django.test.Client() response = client.post(...) then the test code (or thread, I'm not sure) that creates the client object and the post arguments uses test_dbname whereas the thread that serves the post request and generates the response uses dbname (no test_ prepended). This is an inconvenience, because: My test code can't correctly formulate requests (i.e. post data) if such requests should depend on the server thread's database, leading to problems like How to test a Django form with a ModelChoiceField using test client and post method There are now TWO databases under test, whereas the contents of only one of them seems to be controllable from my test code, which makes the tests unpredictable. Can I make the server thread use a database that I can control from the test case thread? -
Django/Python : Sort python's dictionnaries with the equals key
I am currently tring to sort two Python dictionaries into an HTML array such as: #Headers DictA = {'value': 'valeur', 'name': 'nom' } #Data DictB = {'value': '456', 'name': 'Test' } I wanted to sort these two dictionaries in order to get the '456' in DictB equals to the key 'value' in DictA. Note: I used other dictionaries than DictA and DictB, it was just an example. But it fits my problem. In my views.py, I define my two dictionaries such as: headers = json.loads(entries[0].form_data_headers) data = json.loads(entries[1].saved_data) valuesData = data.values() then I pass them into the template.html via the context: context = {'entries': entries, 'form_entry_id': form_entry_id, 'headers': headers, 'data': data, 'valuesData': valuesData} Thus, in my template, it will print an array with the headers (DictA) and the datas (DictB). In my template I make this code: <thead> <!-- Test pr voir si les values sont pris en compte ou non --> <p>{{valuesData}}</p> <tr> {% for entry in headers %} <td> {{ entry }} </td> {% endfor %} </tr> </thead> And the datas are in another for loop: <tbody> <thead> <!-- Test pr voir si les values sont pris en compte ou non --> <p>{{valuesData}}</p> <tr> {% for entry in … -
Django "Violation of PRIMARY KEY constraint" however the primary key is BigAutoField
I have defined a table named ReadUnit. class ReadUnits(models.Model): ReadID = models.BigAutoField(primary_key=True, unique=True, null=False) ReadDate = models.DateField(null=False) The settings.py has the following setting for accessing the database: DATABASES = { 'default': { 'NAME': 'MyProjectDB', 'ENGINE': 'sqlserver_ado', 'HOST': '127.0.0.1', 'USER': 'sa', 'PASSWORD': 'pass', 'OPTIONS': { 'provider': 'SQLOLEDB' }, } } The project was working perfect for several months. Between 30~40 records was added to the table everyday. Recently, I was sometimes facing with a 'Violation of PRIMARY KEY constraint' Error. The code that inserts record to this table is very simple: ReadUnits(ReadDate=str(datetime.datetime.now().strftime("%Y-%m-%d"))).save() Nowadays it becomes awesome because every time this code runs, the error happens. So there isn't any record saved in DB for these days at all. -

Use a javascript array to display specific HTML divs
Using django I have a HTML page with a table containing checkboxes: {% for o in obj %} <input class='germ_ids' name='{{o.id> {% endfor %} <script> var elements = document.getElementsByClassName("germ_ids"); var ids = []; for(var i=0; i<elements.length; i++) { ids.push(elements[i].name); } </script> This has given me an array of specific 'germ ids'. These relate to other django objects I have: the same .html page: {% for k, v in add_state_dict.items %} <div class='{{k.id}}_statement'> <p>{{v}}</p> </div> {% endfor %} <div class='all_germ'> <p>{{additional_statement}}</p> </div> What I want to achieve is a statement for each germ_id when their checkbox is checked. However when more than one boxes are checked, it makes a concat statement called additional_statement in the 'all_germ' class. I have hard coded it in in a JSFiddle http://jsfiddle.net/sDsCM/1037/ However I want to use the elements in the array to do this to account for different array values.
