Hide a button in jQuery after an AJAX call
I have a list of items from a database displayed thanks to a for-loop in Django. I have a "save button" next to each one to save them to a favorite database thanks to an AJAX call. Everything works like a charm. But I want the "save button" to .hide() whenever the AJAX call is a "success". But if I do so, every "save button" from the page is hidden. So I tried to use .parent() or .closest() to select only the <div> where my "save is button" with no luck. My HTML: {% for sub_product in products %} <div class='sub_button'> <form class="add_btn" method='post'>{% csrf_token %} <button class='added btn' value= '{{product.id }} {{ sub_product.id }}' ><i class=' fas fa-save'></i></button> </div> {% endfor %} My AJAX: $(".added").on('click', function(event) { event.preventDefault(); var product = $(this).val(); var url = '/finder/add/'; $.ajax({ url: url, type: "POST", data:{ 'product': product, 'csrfmiddlewaretoken': $('input[name=csrfmiddlewaretoken]').val() }, datatype:'json', success: function(data) { if (data['success']) $(this).parent('.sub_button').hide(); } }); }); -
How to serve an image variable in a response?
When serving a file, we normally include it in the Response as such: response['Content-Disposition'] = f'attatchment; filename="<file-path>"' My issue however is I need to serve an image file from a variable. The image is stored on a different server which is downloaded, stored as a variable, and then needs to be attached to my Response object. Is this possible? Something like the following: import PIL, io from django.http import HttpResponse img = PIL.Image.open(io.BytesIO(photo_bytes)) response = HttpResponse(content-type='image/png') response['Content-Disposition'] = f'attatchment; filebytes="{photobytes}"' -

Django ModelForm not saving any data

Django ORM: child's fields & values not inherited. Objects duplicated. (Using Django admin interface)
I'm trying to have a variety of dishes (Pizza, Subs, etc) that inherit from a common (concrete) parent class Dish. (Logically, I have no reason for it to be concrete other than having had difficulties implementing it). Every pizza (or other concrete dish) corresponds to exactly one dish ID (implemented as FK here) and every dish (ID) is exactly one pizza. I am new to this, but based on my understanding, the shared fields (name, type price, size and dish ID (PK for Dish = FK dish_id for Pizza)) in Dish as well as their values are inherited by children such as Pizza. So much for the theory. Now I implemented the classes as per below. And then I use the Django Admin interface to create objects, but against expectations, when I create a Dish object of type 'Pizza', automatically a Pizza object is created. Now when I go into that Pizza object, the name, type, price and size fields are blank. Shouldn't they be aready set when I select Pizza's dish attribute as the Dish-object I just created? And also when I start by creating a Pizza, selecting the corresponding parent (or creating it in the Django admin interface), … -

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.

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?

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].
