How do I make <a href> link to open in a new tab but in an iFrame part of another template?
I have created a Django web app which throws document recommendation to users based on their search query; the next thing I am trying to achieve is to able to make users open these recommended documents in a new tab but in an iFrame which would part of another template. Also, I just want to use HTML and Python to achieve this result. Till now, I am just able to open the documents in a new tab which is not part of my Django framework <html> <body> {% for document in Documents %} <a href = "{link to the corresponding document on my system}" target = "_blank"> <p><font color = "blue"><b>{{ document }}</b></font></p> </a> {% endfor %} </body> </html> The above code loops through the list of recommended documents generated by model and prints their hyperlinked names on an HTML page. These links just open the document in a new tab but I want them to open in an iFrame on a new template which is part of my Django framework. -
Easiest and fastest way to migrate boto based django-photologue collections on S3 to the newer boto3?
There is a bug (https://github.com/boto/boto/issues/3837) in boto that prevents it from functioning properly with S3 in production (althought it does work in development). How would one go about installing a forked version of boto to the existing project or perhaps migrating the populated storages to boto3? Is it even possible without reuploadin/retaggint my entire collection? and even so, does django-photologue work with boto3? I'm linking to this code from my settings.py, as described in the tutorials for django-photologue s3 storage: # S3Boto storage settings for photologue example project. import os DEFAULT_FILE_STORAGE = 'example_storages.s3utils.MediaS3BotoStorage' STATICFILES_STORAGE = 'example_storages.s3utils.StaticS3BotoStorage' AWS_S3_HOST = 's3-us-west-2.amazonaws.com' AWS_S3_OBJECT_PARAMETERS = { 'Expires': 'Thu, 31 Dec 2099 20:00:00 GMT', 'CacheControl': 'max-age=94608000', } try: # If you want to test the example_project with S3, you'll have to configure the # environment variables as specified below. # (Secret keys are stored in environment variables for security - you don't want to # accidentally commit and push them to a public repository).

Django + Python failed connecting to PostgreSQL server in a local machine in same network
I have a PostgreSQL running in a linux machine inside my local network. The IP address of this machine in my local network is 192.168.0.115. I am able to connect to this server using the Valentina Studio client on my Macbook Pro with username postgres and password postgres, and IP address 192.168.0.115 (address of the linux machine running the PostgreSQL server in my local network). Also in my Macbook Pro, I have a Django application setup to connect to the PostgreSQL server using the same IP address, username and password as the Valentina Studio, but when I run python3.7 manage.py migrate, I get an error message saying it could not connect to server: When I change my Django application database configuration to use SQLite, the migration runs well and everything works well. I disabled the firewall of the linux machine running the PostgreSQL server, just to make sure. (I don't think this is the problem though, because my Macbook Pro is able to connect to that server using the Valentina Studio client). If I run the same Django application INSIDE THE POSTGRESQL SERVER LINUX MACHINE, using 127.0.0.1 IP address, it works. If I change the IP address to 192.168.0.115 (IP … -

django-zappa: Error loading psycopg2 module: libpq.so.5: cannot open shared object file: No such file or directory
When trying to deploy a Django project using django-zappa, I get the following error in the zappa tail output: django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: libpq.so.5: cannot open shared object file: No such file or directory I've made sure to include the psycopg2 module in the requirements file: psycopg2==2.8.3 It's installed in the virtual environment that's active while running the zappa deploy command. I'm running on Linux and had to install libpq-dev via apt before even being able to pip install psycopg2 as I received an error before, saying that libpq was missing on the system (similar to the above error, I guess). How can I overcome this error? Thanks! -
"Is there any repository or documentation with instructions to run docker created by django oscar?"
I am working with Django oscar docker and in the meantime found that Django oscar sandbox not installing as expected. So I want to get rid of all hassles and want to run it in docker.

Hope you guys will come up. This is my github issue link https://github.com/django-oscar/django-oscar/issues/3051 -
How to automatically substitute a variable in the admin page at Django 1.11?
There is a City model. It has a name field. I need to somehow substitute this variable in the admin page in the text field at another models. Suppose need to write the phrase "Your location is Paris", but it is necessary that the name of the city was substituted by itself (since there are many cities, and prescribing for each is not an option at all). That is, there must be something like "Your location - {City.name}" - that is, a certain city is pulled out of the database and substituted into this line. Writing a prepared phrase in templates is not an option. I need to do this through the admin panel. Using selects is also not an option, since the number of variables, their location and phrases are not known in advance. For example, the phrase "The capital of France - Paris" (The capital of {Country.name} - {City.name}). I understand, need to create a shortcode_name field and somehow process it in the view? I'm use Django 1.11 -

How can I filter related field in django?
Say I have the model User which has a many-to-many relation with the model Company; and the model UserType, which is connected to both User and Company. Like this: class User(models.Model): name = models.TextField() class Company(models.Model): name = models.TextField() users = models.ManyToManyField(User, related_name="companies") class UserType(models.Model): name = models.TextField() company = models.ForeignKey(Company, related_name="user_types") users = models.ManyToManyField(User, related_name="user_types") I wanna find all Users in a Company, which is simple enough: User.objects.filter(companies=some_company). However, I also wanna filter the user_types field on the returned users objects, so that only UserType objects connected to the given Company is returned. To explain it with code, this should return true: def check_user_types(users, company): for user in users: for user_type in user.user_types: if user_type.company != company: return false return true How would I do this? -

Django: bulk_destroy returns "400: Bad request"
I have a Django viewset MyModelViewset that extends MultipleDBModelViewSet (from the base viewsets). The base viewset contains the following method that is not overwritten in MyModelViewset: def bulk_destroy(self, request, *args, **kwargs): ids = json.loads(request.query_params.get("ids")) if not ids: return super().destroy(request, *args, pk=kwargs.pop("pk"), **kwargs) else: return super().bulk_destroy(request, *args, **kwargs) I am assuming that this method means I can pass a parameter called ids and all of the objects with those ids will be deleted? I've tried sending a delete request to the associated URL: v1/mymodel?ids=["4cea187e-56af-439c-96a7-e001d85c5000","3d7bd2ac-bc27-4a1b-acfd-9b651852114e"] -> this returns a 200 response and behaves like a GET request v1/mymodel?ids=["4cea187e-56af-439c-96a7-e001d85c5000","3d7bd2ac-bc27-4a1b-acfd-9b651852114e"]/ -> this returns a 400 response "Bad request" MyModels with these ids do exist in my DB.
