This site can’t be reached mysite.com refused to connect. ERR_CONNECTION_REFUSED
I am trying to add social authentication to my Django project and because of this I need to be able to do this: mysite.com:8000/account/login/ instead of this: 127.0.0.1:8000/account/login/ I'm on Ubuntu 16.04 running chrome Version 81.0.4044.92 (Official Build) (64-bit) I have updated INSTALLED_APPS in the settings file in Django to read: ALLOWED_HOSTS = ['mysite.com', 'localhost', '127.0.0.1'] And added the following in /etc/hosts 127.0.0.1 mysite.com I have also cleaered the chrome cache but I still get the following error: "This site can’t be reached mysite.com refused to connect. Try: Checking the connection Checking the proxy and the firewall ERR_CONNECTION_REFUSED" Does anyone know how I can get this to work please? Or even suggest another way to do it. -
How to have 2 different models for user and admin in django and how to manage them?
I am trying to create a social media type website where users can post images, videos, blogs, and meantime they can see other user's postings. I want to have 2 different models. One for users and another only for admins and moderators of the website. Admin and moderators can log in to the admin panel and edit the website. The users can only post certain things, delete their posts or update and add other users as friends/followers. In default option in Django, the users and admins are in the same model/table of a database. So is there any way to separate them? The users will be able to log in to the website. If I create 2 different models for users and admin how will I be able to authenticate the users when they will try to login to the base website where they will post things? How will I be able to set the Request.user? What will be my auth_user_model? I have created 2 different databases for this thing. One is for the admin and user DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'admin', 'USER': '#user', 'PASSWORD': '#password', 'HOST': 'localhost', 'PORT': '5432', }, 'user':{ 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'user', … -

How to load django objects requesting DB once and do searches after
Suppose I have a QuerySet of all db entries: all_db_entries = Entry.objects.all() And then I want to get some specific objects from it by calling get(param=value) (or any other method). The problem is, that In documentation of QuerySet methods it is said: "These methods do not use a cache. Rather, they query the database each time they’re called.". But what I want to achieve is to load all data once (like doing Select *), and only after do some searches on them. I don't want to open a connection to the db every time I call get() in order to avoid a heavy load on it. -

Using custom query in django-filters
I'm trying to filter a Model using Filterset (django-filter) and render from/to select form field in my Template. Unfortunately I cannot figure out how to get it working. While my code and power_category fields render fine, only a text field gets displayed when trying to render the reported field, unless I set type="date", then the datepicker pops up when clicking the date field; however only one shows up (need two, to, and from to select the range). -
Django query to remove older values grouped by id?
Im trying to remove records from a table that have a duplicate value by their oldest timestamp(s), grouping by ID, so the results would be unique values per ID with the newest unique values per ID/timestamp kept, hopefully the below samples will make sense. sample data: id value timestamp 10 10 9/4/20 17:00 11 17 9/4/20 17:00 21 50 9/4/20 17:00 10 10 9/4/20 16:00 10 10 9/4/20 15:00 10 11 9/4/20 14:00 11 41 9/4/20 16:00 11 41 9/4/20 15:00 21 50 9/4/20 16:00 so id like to remove any values that have a dupliate value with the same id, keeping the newest timestamps, so the above data would become: id value timestamp 10 10 9/4/20 17:00 11 17 9/4/20 17:00 21 50 9/4/20 17:00 10 11 9/4/20 14:00 11 41 9/4/20 16:00 -

Updating and saving dict in django with post requests
I am trying to make a responsive tournament bracket with python/django and using $.post requests to update a tournament dict - which I pass to a 'bracket' template as a dictionary, render, then update by $.posting the passed in variable to a nother view, which updates, saves to server, then redirects to 'bracket' view. I am just starting to make some progress, but having issues with reformatting of the bracket object. Little more detail The bracket is initialized in python (in my views.py) in a bracket view, but I am calling in the view a Tournament class that I got from here. the Tournament class takes a list of players and then generates a dictionary corresponding to the games with the method t.generate_bracket(). I kind of restructure this and then pass it into a bracket view for displaying - I display the restructured array in my template but also pass in the un-restructured one I have little radio buttons that are bound to a $.post 'update_bracket' view. In the JS $.post, I send the array to the view, where I will call a t.play_game() method to update the bracket. Then - instead of a JSON or HTTP response and subsequent … -

Change one instance variable when creating another instance
I am making an app to create repair work orders which also has an inventory app in it. I create and edit repair work orders using class-based views. I have a model for work orders; class Order(models.Model): """Maintenance work orders""" ... parts = models.ManyToManyField(Part, blank=True) and model for parts inventory class Part(models.Model): """List of company equipment""" partnum = models.CharField(max_length=20) amount_in_stock = models.PositiveIntegerField() price = models.FloatField(blank=True, null=True) vendr = models.ManyToManyField('Vendor', blank=True) ...

What i can't figure out is, how i change instance variable Part.amount_in_stock from instance of Order. I create and edit orders using class-based views. The idea was i create a new sub-class class UsedPart(Part): """Part used in Repair""" used_in = models.ForeignKey('mtn.Order', on_delete=models.CASCADE) used_amount = models.PositiveIntegerField() def cost_of_repair(self, *args, **kwargs): super(Part, self).__init__(*args, **kwargs) price = self.price def __init__(self, *args, **kwargs): cost_of_repair = self.used_amount * price return cost_of_repair def __init__(self, *args, **kwargs): used_amount = self.used_amount super(Part, self).__init__(*args, **kwargs) self.amount_in_stock = self.amount_in_stock - used_amount And then i initiate it from Order UpdateView class AddPartView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = Order But since i've only started learning python, i didn't get the hang of … -

JQuery: Posting Files with FormData-Objects
So i am using a ModelForm for an updateview and want to append some files using a Javascript FormData-Object, submiting the whole form using JQuery. It seems, that the Image-Files dont get posted. views.py: class SowiUpdateView(UserPassesTestMixin, LoginRequiredMixin, UpdateView): def post(self, request, *args, **kwargs): print(request.POST) return super(SowiUpdateView, self).post(request, *args, **kwargs) The javascript: var formData = new FormData(document.getElementById("form_id")); for (var i = 0, len = filesToUpload.length; i < len; i++) { // filesToUpoad is a List containing a dict, with file i access the file formData.append("files", filesToUpload[i].file); } $.ajax({ headers: { "X-CSRFToken": getCookie("csrftoken") }, url: "{% url 'sowi-update' object.id %}", data: formData, contentType: false, processData: false, async: false, method: 'POST', type: 'POST', success: function (data) { // console.log(data); }, error: function (data) { console.log("ERROR - " + data.responseText); } }); Strangely, the serverside-post-data-output gives all the FormData-Data but the "files"-object. What's wrong? I Tried just appending a string instead of a file, and that worked. Thanks for your help!! -

django-simple-history is storing changes twice
I tried django-simple-history and I discovered that every create or update is stored twice in the history model. I don't know which information is now useful for you to help me, but I use CBV's and model forms. I followed the instructions on how to install and setup and everything works fine. What I'm wondering is why there is a command line called clean_duplicate_history, which indeed removes all duplicates records. Thank you in advance for any help. -
