Add seperate self contained php landing page to Django CMS
Completely new to Django and can't seem to find advice regarding this in the docs: In summary, there is a site that is built and managed with Django. I have a self-contained php landing page (with a form) ready to go, that I would like to integrate into the site and the URL structure like follows: djangosite.com/selfcontainedlandingpage I have access to the server to upload the site files but am very unfamiliar with the structure. (of course, I don't want or need this to be integrated into the CMS - just to be on the server and in the URL structure as above) Is this possible? Any advice or a point in the right direction greatly appreciated. -
dango-crispy-forms error keeps interferring with project even after uninstallation
I was trying to embed django crispy forms into my project which gave me an "Module not found" error which I couldn't figure. So, I uninstalled it, but even after uninstallation, this thing throws me this error when I run the local server and even migrate.

How to log a user out in django (without the request)
In django I can log a user out with: from django.contrib.auth import logout logout(request) However, how would I manually log a use out -- for example I want to "sign users out of all tabs" -- that is, how do I flush all session for that user in my db? -
Django test database requires Postgres Extension enabled
I have a Django app which requires Postgres' fuzzystrmatch extension to be enabled on the database. Django's unittest framework creates and destroys a new database. I need this new database to have the extension turned on for testing. I can use './manage.py test --keepdb' to keep the database and then manually turn on the extension, but this is an ineloquent solution. Any idea how I can enable this extension programmatically? -
How to delete all nested objects referenced to an object?
I have a model which is set as foreign key in several models. Right now deleting any object from the model throws ProtectedError if it is referenced in any of those model. I want to let user delete the object with all protected objects in a single operation. I can delete the first layer of protected objects by simply calling .... except ProtectedError as e e.protected_objects.delete() .... But when the protected_objects have their own protected objects, the operation fails and throws another second layer ProtectedError. What I want to achieve is, deleting all the protected objects undiscriminating in which layer it exists. I am aware that it can be a dangerous operation to perform. But can I achieve this without a complex solution. Thanks in advance. -

Issue while running Django and Nginx on separate docker containers
I am experimenting with docker containers. Trying to run a Django application in a Docker container and serving it using Nginx(not containerized) and it works fine. But when I am trying to containerize Nginx and use that container to serve the Django container it is not working. When I hit the IP of the server, I am able to get only the Nginx test page. So I am confused how to do it. I am using a similar Nginx.conf file in the container which is working initially. -
Docker does not copy all my static files?
I'm trying to run a django project in the docker container. The django project is running, but I can't see the styles because some of my static files aren't copied. Dockerfile: FROM python:3.6 RUN mkdir -p /opt/services/djangoapp/src WORKDIR /opt/services/djangoapp/src COPY Pipfile Pipfile.lock /opt/services/djangoapp/src/ RUN pip install pipenv && pipenv install --system COPY . /opt/services/djangoapp/src EXPOSE 8000 CMD ["gunicorn", "--chdir", "udk", "--bind", ":8000", "mydjango.wsgi:application"] When I write COPY . /opt/services/djangoapp/src as above , I can only see the following static folders in the target directory: └── static ├── admin └── ckeditor therefore, my still files are not uploaded and I am only viewing text on the site. my project tree: ├── config │ ├── nginx │ │ └── mydjango.conf │ └── requirements.pip ├── docker-compose.yml ├── Dockerfile └── src ├── manage.py └── mydjango ├── __init__.py ├── settings.py ├── urls.py └── wsgi.py └── static ├── admin ├── ckeditor ├── css └── js └── img I want to copy all the files in the static folder inside the container.

Django Haystack override class's index_queryset in subclass
I'm using Django Haystack (with Aldryn Search) to search content on a client site. However, we need to modify the Articles indexed from the Aldryn NewsBlog plugin - Articles assigned to the Intranet Section should not be indexed. So I made a subclass in my plugin to override that like the documentation says to do: Subclasses can override this method to avoid indexing certain objects. However, when I try to rebuild the index it says: aldryn_newsblog.models.Article has more than one 'SearchIndex`` handling it. Please exclude either aldryn_newsblog.search_indexes.ArticleIndex object or search_modifier.search_indexes.BlogHelperIndex object The documentation is not clear to me what I need to write to have this modify the existing index from the NewsBlog plugin. I don't want to totally exclude it like the error is suggesting, but to subclass it like the documentation says to do. Here is my search_indexes.py file: from aldryn_newsblog.search_indexes import ArticleIndex class BlogHelperIndex(ArticleIndex): def index_queryset(self): # make sure only public posts are pulled return self.get_model().objects.exclude(app_config__app_title='DirectConnection') -
How to add custom preprocessor/postprocessor to django-wiki render?
I am planning to add my custom "syntax extension" to my wiki based on django-wiki (https://github.com/django-wiki/django-wiki). For example I want something like this: {mytemplate param1="value"} to unfold to something like that: <div class="mytemplate"><some_code_that_uses_param1></div> So, how add such custom syntax extension to django-wiki? (I'd prefer to do it without modifying django-wiki's source code) -
Azure Web App for Container can't connect to Azure DB for Postgres
I have a Azure Web App for Containers. I am trying to get the web app to connect to a Azure Database for Postgres. The web app gave me an error "OperationalError: could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?" From the portal, I have granted "Allow access to Azure services" and included all the IPs in the rules. Is there anything I have missed? Thanks. -

Heroku migrate: ModuleNotFoundError (suspect issue with static)
I am having an identical problem as here, and here, and here. However, I have attempted the answers given in each of those queries, to no avail. In attempting to deploy an application, from the following command: heroku run python manage.py migrate ERROR ModuleNotFoundError: No module named 'decouple' I suspect that the issue is caused by how I am deploying static. Especially since the command: python manage.py collectstatic returns the following error: FileNotFoundError: [Errno 2] No such file or directory at: '/mnt/project/static/'.

How do I inputs from an HTML page to a script in Django?
I am making a page so that my python script can run using django which requires 3 inputs. In my app I have made a folder where I write and run the HTML commands with 3 inputs and a submit button which works fine. The python script this webpage will run with the three inputs has already been written but I am not sure where to put them or how to pass in the variables after they have been submitted. I am getting a lot of mixed messages telling me to use urls.py, views.py, or make my own utils.py. Should I make a new file for the script or write it in one of the provided files (admin.py, init.py etc)? How can I pass in those values and then have the script run automatically after? Thanks! -
Django testing - wait for subprocess to be ready
I'm using pouchdb-server to create an in-memory database to run my test against with the following code: class CouchdbTestCase(TestCase): def setUp(self): self.proc = subprocess.Popen('pouchdb-server --in-memory', shell=True) time.sleep(1) def tearDown(self): process = psutil.Process(self.proc.pid) for proc in process.children(recursive=True): proc.kill() process.kill() the time.sleep(1) is there as otherwise the tests are ran before the in-memory server is ready Is there a more graceful way to ensure the server is ready without having to do such a long wait? -
Query to check if parent data is associated with unrelated data through a lookup table
Sorry for the confusing title. If someone can suggest, please do. I have this 4 models: Parent() Child(): parent= models.ForeignKey(Parent,related_name='parent_child') Member() MemberChild(): member= models.ForeignKey(Member, related_name='member_child') child = models.ForeignKey(Child, related_name='child_member') Now, what I want is to list all parents and see if they are in use by the logged in member. Sample Data: Parent 1 Parent1 2 Parent2 Child 1 1 Child1 Member 1 Member1 MemberChild id child member 1 1 1 Now the expected output is (for member id 1): Parent1 True Parent2 False in which True means any Child of parent1 is currently being used by the member. -

Filter django for objects containing subsets of same many to many relationship
In my database I have user objects with two many to many fields (messages and following) on them that both contain a many to many field related to another object Topic. I want to filter for all "users" who have "messages" attached to them that do not contain all of the topics attached to the "following" objects on the user. Right now I am useing a loop to accomplish this: users = set() for user in User.objects.filter(messages__isnull=False, following__isnull=False).iterator(): if not set(user.messages.values_list('topics', flat=True) ).issubset(set(user.following.values_list('topics', flat=True))): users.add(user.pk) Is there a way to accomplish the same thing with a single query? I've tried variations of annotate, aggregate, and F() queries but I wasn't able to accomplish what I'm looking for.
