Linking Foreign key between tables in django models
I am just starting out with Django and so please help me out with my doubt. Currently, I have three tables Topic, Webpage, and AccessRecord. In the third table AccessRecord, I have used a ForeignKey with the second table Webpage. But Webpage table has three attributes topic, name, and URL ..so my doubt is which attribute of these three will be treated as a Foreign key to AccessRecord table. Any help will be greatly appreciated. class Topic(models.Model): top_name = models.CharField(max_length=264,unique = True) def __str__(self): return(self.top_name) class Webpage(models.Model): topic = models.ForeignKey(Topic,on_delete=models.CASCADE) name = models.CharField(max_length=264,unique=True) url = models.URLField(unique=True) def __str__(self): return self.name class AccessRecord(models.Model): name = models.ForeignKey(Webpage,on_delete=models.CASCADE) date = models.DateField() def __str__(self): return str(self.date) -
Sentry cloud database migration: Cannot see the migrated data in the new Sentry install
Here is the issue I am seeking to resolve: I am in the process of migrating a production Sentry instance (hosted on Nomad) onto a new new install (hosted on AWS ECS), both currently on version 9.0.0. Both the current and the new Postgres databases are hosted in AWS RDS. Same for Redis, they are both managed by AWS (i.e. ElasticCache). I have used two methods to migrate the database: (1) AWS RDS snapshot/restore, and (2) pg_dump, and pg_restore methods; and both worked successfully from the database perspective. The new database seems fine to me, with all tables exactly the same as the original database. However, when loading and hitting the new hosted Sentry instance, I can only see one empty Sentry organization, no teams, no project. Empty. I haven’t migrated the Redis database, but I can’t see why this would be the cause of it, given it’s a cache mechanism only. The source Sentry install instance also uses SAML2 for SSO. I cannot see any of that configuration, and any of that original data in the new install. What am I missing? Thank you. -

How can I solve "cannot import name 'main' from 'virtualenv'"?
When I try running virtualenv I get the following error: [jelly@laptop Getskilled]$ virtualenv venv Traceback (most recent call last): File "/usr/bin/virtualenv", line 6, in <module> from virtualenv import main ImportError: cannot import name 'main' from 'virtualenv' (/home/jelly/.local/lib/python3.8/site-packages/virtualenv/__init__.py) Virtualenv was working when I last used it for a project so I am guessing that an update cause it to break. I have tried reinstalling virtualenv and pip. The closest post I could find was this one: virtualenv: cannot import name 'main' I tried following this post so I ran the following in the python interpreter: import virtualenv virtualenv.__file__ Which returned: '/home/jelly/.local/lib/python3.8/site-packages/virtualenv/init.py' However, there was no file /usr/local/bin/virtualenv.py and there is no virtualenv.py in the .local directory so that solution in that post won't work for me. What can I try next? -
Send Form Content to Endpoint in Different App Django
Say I have an app called App1 - inside of which there is a template that has a form with name and email. Now, say I have an app called App2 - that has an endpoint which takes in a name and email and sends an email to that email. Now, I want to combine the two, so that I can make the form contents go to the endpoint in App2 on submit, thus sending an email to the email in the form. How would I do this? Would it be better to just put them in the same app? When would someone use 2 apps over 1? Does this make sense? Thanks for your help! -
Tyring to understand WSGI interface in Django
I was recently trying to undestand the what is WSGI application: a WSGI application is just a callable object that is passed an environ - a dict that contains request data, and a start_response function that is called to start sending the response. In order to send data to the server all you have to do is to call start_response and return an iterable. So, here's a simple application: def application(environ, start_response): start_response('200 OK', [('Content-Type', 'text/html')]) return ['Hello World!'] The Djangos wsgi.py is """ WSGI config for basic_django project. It exposes the WSGI callable as a module-level variable named ``application``. For more information on this file, see https://docs.djangoproject.com/en/2.2/howto/deployment/wsgi/ """ import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'basic_django.settings') application = get_wsgi_application() But when i see the wsgi.py the application = get_wsgi_application() object does not get passed with environ or start_response function So how to understand this -
Should I change password settings in Django or leave it as it is?
If I am building a website such as social media or even ones where there will be monetary transactions by users, is it a good idea to change the password settings for better security or do the default password settings incorporate better security measures in most cases? -
Django clone recursive objects
previously I have a problem when I want to clone the objects recursively. I know the simply way to clone the object is like this: obj = Foo.objects.get(pk=<some_existing_pk>) obj.pk = None obj.save() But, I want to do more depth. For example, I have a models.py class Post(TimeStampedModel): author = models.ForeignKey(User, related_name='posts', on_delete=models.CASCADE) title = models.CharField(_('Title'), max_length=200) content = models.TextField(_('Content')) ... class Comment(TimeStampedModel): author = models.ForeignKey(User, related_name='comments', on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) comment = models.TextField(_('Comment')) ... class CommentAttribute(TimeStampedModel): comment = models.OneToOneField(Comment, related_name='comment_attribute', on_delete=models.CASCADE) is_bookmark = models.BooleanField(default=False) ... When I clone the parent object from Post, the child objects like Comment and CommentAttribute will also cloned by following new cloned Post objects. The child models are dynamically. So, I want to make it simple by creating the tool like object cloner. This snippet below is what I have done; from django.db.utils import IntegrityError class ObjectCloner(object): """ [1]. The simple way with global configuration: >>> cloner = ObjectCloner() >>> cloner.set_objects = [obj1, obj2] # or can be queryset >>> cloner.include_childs = True >>> cloner.max_clones = 1 >>> cloner.execute() [2]. Clone the objects with custom configuration per-each objects. >>> cloner = ObjectCloner() >>> cloner.set_objects = [ { 'object': obj1, 'include_childs': True, 'max_clones': 2 }, … -
How to filter a ForeignKey in Django Model
I'm trying to filter a field to be shown in the Django admin form: class Buy(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE) quantity = models.PositiveIntegerField() image = models.FileField(upload_to='images/') date = models.DateTimeField() buy_price = models.DecimalField(max_digits=6, decimal_places=2) sell_price = models.DecimalField(max_digits=6, decimal_places=2) def __str__(self): return f'DM {self.id}' class Sell(models.Model): item = models.ForeignKey(Buy, on_delete=models.CASCADE) def __str__(self): return f'DM {self.id}' The issue is: the Django admin form must show only item > 0 in the Sell model. How can I do that with ForeignKey relationship in a simple way? I tried limit_to but it didn't work with greater than values. -

How to visupadding and margins in django templates and reducing white space between rows in bootstrap
I'm new to html and Django, and Bootstrap. I sometimes have trouble understanding the padding and margins. Is there some kind of clever way to use CSS to show the padding and margins visually. From what I can tell margins don't have a background color and are transparent. For example in the code below I would like to reduce the vertical space between the fields so the form would be more compact. If I just use HTML I don't seem to have a problem, but when I am using widget_tweaks I get additional space between the rows. {% load widget_tweaks %} {% block content%} <div class="containter p-4"> <div class="py-0 text-Left"> <div> <h2>Just a title for the page:</h2> </div> <form action="{% url 'addINNO:add_new' %}" method="POST"> {% csrf_token %} {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} {% for field in form.visible_fields %} <div class="row py-0 "> <div class="form-group py-0 col-9"> <div class="form-group py-0"> <label for="{{ field.id_for_label }}">{{ field.label }}</label> {% if field.id_for_label == 'id_description' %} {{ field|add_class:'form-control p-0'|attr:"rows:3"}} {% for error in field.errors %} <span class="help-block">{{ error }}</span> {% endfor %} {% elif field.id_for_label == 'id_comment' %} {{ field|add_class:'form-control p-0'|attr:"rows:2"}} {% for error in field.errors %} <span … -

how to use keras model that passed from other python file at django
First I work in django-envirment. I want to load keras model from settings.py and pass the model to function.py so that I can use the model in functions.py. but I'm getting the following error: InvalidArgumentError at /camera2/ Tensor input_1:0, specified in either feed_devices or fetch_devices was not found in the Graph Some people answer this type of error to use this code: from tensorflow import Graph, Session import tensorflow as tf import keras thread_graph = Graph() with thread_graph.as_default(): thread_session = Session() with thread_session.as_default(): model = keras.models.load_model(path_to_model) graph = tf.get_default_graph() and def _load_model_from_path(path): global gGraph global gModel gGraph = tf.get_default_graph() gModel = load_model(path) But that didn't work for me and I guess that answer works for loading model in multi threaded case.

What is the best practice for storing glabal variables of a django App?
There are a few variables that are unique for my website. For Illustrative purposes let's assume it is a Blog, and the variables I am interested in are the total number of users, the total number of posts, the total number of comments in posts, the average length of a user session, and a few others. I can create a model with these parameters, and it will have a single row with all the values, but this might be a bit of an overkill. I was wondering if there was a better (pythonic?) way of doing this. -

Django checking if same object exists in database when user trie to add object:

Deploy Django app on Raspberry Pi with Domain Name
I am creating an application which will need to access a database. Since it is a small scale application I do not want to spend a ton on hosting and have a pi lying around. My plan was to have an SQL server and some sort of API on a pi and access it from the application (on other networks also). Is there an easy way to access a Django app via a purchased domain name on the pi and if so could someone list the basic steps. Otherwise, is it just better to spend a few dollars a month to host it on Digital Ocean or something similar? Thanks in advance. -

Django-Filters Lookup_expr type 'AND'
Does Django-Filters have a lookup_expr equivalent to 'AND'? I am using Django filters with DRF to filter by multiple categories on the same field. Example: I have a category list field that accepts multiple categories categories = ['baking', 'cooking', 'desserts', 'etc'] Using the solution outlined by udeep below I got the filter to work rather well https://stackoverflow.com/a/57322368/13142864 The one issue I am running into is with the lookup_expr="in" This works as an 'OR' expression. So if I provide a filter query of categories=baking,cooking It will return all results that contain either 'baking' OR 'cooking' Is there a lookup_expr in django_filters that profiles an 'AND' functionality so that when I make the same query I get only results that contain both 'baking' AND 'cooking'? I have looked at all of the django filter docs https://django-filter.readthedocs.io/ And all of the django queryset filter where many of these type of filters seem to originate from https://docs.djangoproject.com/en/3.0/ref/models/querysets/ But unfortunately, I have had no luck. Any direction you can provide would be much appreciated. -
