Specific email required during signup
Django 2.1.5 Python 3.7 I'm trying to have my signup form only accept .edu emails. Right now it accepts any kind of email that has an @ sign in it. -
Which model relationship should I be using?
I have the following in my models.py class items(models.Model): name = models.CharField(max_length=255) item_image = models.ImageField(upload_to='itemimage/', default=None, blank=True) price = models.DecimalField(decimal_places=2, max_digits=100) class comparelist(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) item1 = models.ForeignKey(items, on_delete=models.CASCADE, null=True, blank=True) item2 = models.ForeignKey(items, on_delete=models.CASCADE, null=True, blank=True) item3 = models.ForeignKey(items, on_delete=models.CASCADE, null=True, blank=True) item4 = models.ForeignKey(items, on_delete=models.CASCADE, null=True, blank=True) The idea is to allow a user to add 4 different items to their account so they can compare them. But when I makemigrations, I get the following error: compareapp.comparelist.item1: (fields.E304) Reverse accessor for 'comparelist.item1' clashes with reverse accessor for 'comparelist.item2'. HINT: Add or change a related_name argument to the definition for 'comparelist.item1' or 'comparelist.item2'. I'm assuming ForeignKey is not the relationship field to use here. I tried reading django docs on relationship fields but I can't get my head around it. Can someone give me a simple explanation on the 3 different relationship fields? And which one should be used in this situation? -

How can I get super detailed Django debug info?
I have a very difficult to diagnose Django problem in which sometimes the server locks up for a period of time many attempts to debug it have not succeeded. So I need to see at the most detailed level possible what Python is doing. Ideally I would have some sort of output log sitting somewhere dumping vast amounts of info the the screen until the problem occurs then I can see exactly what was happening at the point of hang. Can anyone suggest the most effective way to get this information dumped out of Django? All the searches that I do for Django debugging refer only to application level debugging - I need to go lower. -
Problem with Django app unit tests under Visual Studio Code
I have a draft of the Django project with the added one application (e.g. my_app). In this app I have places tests.py file with one test: import unittest class Test_MyModel(unittest.TestCase): def test_dummy(self): self.assertEqual(1,1) In this case, this dummy test is discoverd by Visual Studio Code and could be executed in it, also it's possible to launch this test from command line: python manage.py test When I modify my file with unit test add import some model (placed in file models.py) from my_app: import unittest from .models import MyModel # new added line class Test_MyModel(unittest.TestCase): def test_dummy(self): self.assertEqual(1,1) In this case I'm still be able run test from command line without any problems, but VSC doesn't discover my test and in the Python Test Log in the VSC I get error: ====================================================================== ERROR: tests (unittest.loader._FailedTest) ---------------------------------------------------------------------- ImportError: Failed to import test module: tests Traceback (most recent call last): File "/usr/local/Cellar/python/3.7.1/Frameworks/Python.framework/Versions/3.7/lib/python3.7/unittest/loader.py", line 434, in _find_test_path module = self._get_module_from_name(name) File "/usr/local/Cellar/python/3.7.1/Frameworks/Python.framework/Versions/3.7/lib/python3.7/unittest/loader.py", line 375, in _get_module_from_name __import__(name) File "/Users/myuser/Projects/backend/my_app/tests.py", line 3, in <module> from my_app.models import MyModel File "/Users/myuser/Projects/backend/my_app/models.py", line 4, in <module> class MyModel(models.Model): File "/Users/myuser/Projects/virtualenvs/my_app_env/lib/python3.7/site-packages/django/db/models/base.py", line 103, in __new__ app_config = apps.get_containing_app_config(module) File "/Users/myuser/Projects/virtualenvs/my_app_env/lib/python3.7/site-packages/django/apps/registry.py", line 252, in get_containing_app_config self.check_apps_ready() File "/Users/myuser/Projects/virtualenvs/my_app_env/lib/python3.7/site-packages/django/apps/registry.py", line … -
How to update django model through data in foreignkey fields?
I am trying to migrate some data from one table to another, and I have the following script: def forward_func(apps, schema_editor): targetModel = apps.get_model("target", "some_target") targetModel.objects.all().update(a='other__table__a') both fields are boolean, and the data inside the original table has no problem and has correct type. For some reason, I'm getting this message: ValidationError: [u"'other__table__a' value must be either True or False."] From the django doc (v1.11), I can't really find a topic talking directly about this, but I've found However, unlike F() objects in filter and exclude clauses, you can’t introduce joins when you use F() objects in an update – you can only reference fields local to the model being updated. If you attempt to introduce a join with an F() object, a FieldError will be raised: # This will raise a FieldError >>> Entry.objects.update(headline=F('blog__name')) Does that mean I simply cannot call .update using foreinkeys? Do I have to loop through every object and update this way? -

Send POST request from ember to specified URL
I am new to full stack development, and having an issue with a web application I'm working on for my employer. I was tasked with creating a fairly simple application that we can scale over time. For now all that it needs to do is take data from one of our databases, and pass it to a front end application. Using this front-end app our workers should be able to double check the information passed in, and make sure it has been properly translated to a new format. After it is translated I want to send an HTTP POST request to our new systems back-end and have it add this new data via the REST API. Essentially it's an application that was used for practice to get me more acquainted with full stack development while making an effective tool to transfer mass data from one system to another. I can't seem to figure out how to set up something in ember.js to send that POST request to somewhere other than my back-end though. -

CSV upload to database does not seem to work
I'm setting up a web app that allows user to upload a CSV file that saves to MEDIA_ROOT and updates the database with the CSV data. However, I can't seem to get it to work.

Python Django website installed from Git(hub) with pip
I would like to create a package for a Django website on Git(hub) which can be installed with pip, and run with whatever server is configured (I'm using uWSGI at the moment). How can I create a new wsgi.py that will import both the app AND project files from the virtual environment installed packages? I understand how just the app would work, but not the project itself. I would like this Django website to be distributed as a whole, with the user only needing to change the settings for their environment (various settings, SECRET, etc.). This is the default wsgi.py that Django creates: import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings') application = get_wsgi_application() The imports themselves should be fine, and I assume that I would point the environment variable to my virtual environment package and settings file like so: import my_project os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'my_project.settings') and in the settings file, I would import the custom settings project based on the actual file location. That leaves the project urls.py and I haven't any idea on what to try there since I can't find any reference to it. Since I can't find any references, do people not create pip packages from the project? -
How can I restrict an authenticated user from posting on behalf of someone else?
If I am logged in as user1 and I am accessing a ViewSet called RecipeSubmissionViewSet, the POST takes a recipe_id of the recipe the user wants to submit. How do I ensure that user1 does not submit user2's recipe, assuming the Recipe model has an owner field on it and I can just compare it to request.user? Should I use a permission class for this or is there a better way? I'm speaking from an backend point of view and not taking into account that the front end would of course filter out the recipes that belong to the user and only show them their own recipes. -
Call Python script from SQL trigger
I have the following scenario: users can log in and update certain tables, and whenever that table is updated I would like to call a Python script that will query the same database for additional information (joins) and then use Django's email system to email all users in that group (same role) that information. My current methodology is to create a user-defined function in SQLite3, and then create a trigger that will call that function (which is linked to a Python file). Is this possible with SQLite? Django app, SQLite and Python. import sqlite3 def email_materials_submittal(project_id): print(project_id) con = sqlite3.connect('../db.sqlite3') con.create_function("FUNC_EMS", 1, email_materials_submittal) con.commit() cur = con.cursor() cur.execute("CREATE TRIGGER TRIG_EMS AFTER INSERT ON core_level BEGIN SELECT FUNC_EMS(NEW.project_id); END;") con.commit() con.close() I want SQL to call an external Python script whenever a new row is inserted into a certain table.

Fix postgersSQL column to be a timestamp with Django's deafult ORM?

How assign existing, nested objects in serializer?
I've got Membership class which contains 3 ForeginKey fields. These FK always have to reference to already existing objects so I'm wondering how simplify create and update methods inside MembershipSerializer in order to assign these fields using only keys passed in request. Here's MembershipSerializer class code: class MembershipSerializer(serializers.ModelSerializer): user = UserSerializer(many=False) club = ClubSerializer(many=False) inClubRole = InClubRoleSerializer(many=False) class Meta: fields=( 'user', 'club', 'inClubRole', ) model = Membership def create(self, validated_data): print(validated_data) user_data = User.objects.get(id=validated_data.pop('user')) club_data = Club.objects.get(id=validated_data.pop('club')) inClubRole_data = InClubRole.objects.get(id=validated_data.pop('inClubRole')) instance = Membership.objects.create(**validated_data) instance.user=user_data instance.club = club_data instance.inClubRole = inClubRole_data return instance Since User, Club, and InClubRole models already exists I want to simplify POST and UPDATE for Membership class just by passing Primary Keys like that: { "user": 1, "club": 1, "inClubRole": 4 } However create methods still expects passing every field related with User, Club and InClubRole classes. How to fix that? Or maybe there is a simplier way to handle with it? -

Django template sidebar not rendering as it should

Instead of coming up on the right hand side of the content, as it does for the other pages that have similar content, the side bar in this case is at the very bottom.

How to specify which value is returned for a foreign field when serialising data in a view in Django
I have a model containing a ForeignKey to another model. I am attempting to serialize this model and want to control what field is returned for the foreignkey field. See below: models.py class Surveyor(models.Model): num = models.CharField(max_length=3) name = models.CharField(max_length=250) class Anblsrecord(models.Model): ... sur_num = models.ForeignKey(Surveyor, on_delete=models.CASCADE) views.py def anbls_points(request): points_as_geojson = serialize('geojson', Anblsrecord.objects.all()[:5], fields=(... 'sur_num')) return JsonResponse(json.loads(points_as_geojson)) When I view this I get: ... "sur_num": 1 ... where the "1" is "num" from Surveyor class. I want to return "name". I looked at https://docs.djangoproject.com/en/2.2/topics/serialization/ which talks about multi-table inheritance, but I can't find anything for a related table. Any help would be greatly appreciated. -
In the Wagtail admin, is there an equivalent to the Django admin's save_model method?
I have a model whose instances I would like to restrict to a particular site, and so I want to automatically save the site with the model. I've defined a TenantAwareModel from which I inherit when defining site-specific models: class TenantAwareModel(models.Model): class Meta: abstract = True tenant = models.ForeignKey(Site, on_delete=models.CASCADE) Wagtail provides the site as part of the request, so in the wagtail_hooks.py file I wanted to override save_model in the same way as can be done in the regular Django admin. However, I've just discovered that there is no save_model method on Wagtail's ModelAdmin. Is there a way to intercept a save in the Wagtail admin in order to insert a value that is taken from the request object (in this case the site) into the model?
