Django: Comment Section under each post? Two models, one template
I am trying to make a Social Media Platform as a way to better understand Django, and am stuck on the commenting section. I would like to have a comment section, under each post that a user creates. However, I am struggling with handling multiple models on one template. I am not sure where to go from here, and any direction/advice would be appreciated. #views.py class Text_List(LoginRequiredMixin, ListView): model = Text_Post template_name = 'main1/includes/h_post.html' context_object_name = "posts" def get_context_data(self,**kwargs): data = super().get_context_data(**kwargs) return data class Text_Post_P(LoginRequiredMixin, CreateView): model = Text_Post fields = ['T_Post_content'] template_name = 'main1/h_platform.html' def form_valid(self,form): form data has be stated form.instance.T_Post_author = self.request.user return super().form_valid(form) class Commenting_P(CreateView): model = Commenting fields = ['Comment_content'] template_name = 'main1/includes/comment.html' #Not sure what to put here. #models class Text_Post(models.Model): T_Post_content = models.CharField(max_length = 200,verbose_name = "") T_Post_published = models.DateTimeField(default = datetime.now) T_Post_author = models.ForeignKey(User, on_delete = models.CASCADE, default = None, null = True) T_Post_likes = models.IntegerField(default=0) def __str__(self): return self.T_Post_content[:10] class Meta: ordering = ('-T_Post_published',) class Commenting(models.Model): Comment = models.ForeignKey(Text_Post, on_delete = models.CASCADE,related_name="comments", blank = True, null = True) Comment_author = models.CharField(max_length = 100, default = None, null = True, blank = True) Comment_content = models.TextField(default = None) Comment_published = models.DateTimeField(default … -
Django Admin Change List Queryset
I'm adding a total row to django admin following the response here: SO answer. I'm not allowed to show the individual costs on a column, so I can't use django admin totals library or django totalsum, because they require the column to be on list_display. The problem I'm having is that I need to filter or exclude by pay_type but when I try to write the query I get: assert not self.query.is_sliced, AssertionError: Cannot filter a query once a slice has been taken. How can I make this work with a filter? Admin.py - I tried: class MyChangeList(ChangeList): def get_results(self, *args, **kwargs): super(MyChangeList, self).get_results(*args, **kwargs) b_queryset = self.result_list.exclude(cost__paytype_id = 3) b = b_queryset.annotate(total_executed_hours= Sum('cost__bill_hours')) self.executed_hours = b['total_executed_hours'] Also tried: b = self.result_list.exclude(cost__paytype__id = 3)\ .aggregate(total_executed_hours=Sum('cost__bill_hours')) I tried a bunch of other combinations. How can I make this work? Thanks! -
Search bar no content is returned
Hey i am new to Django and I am trying to make a search bar to my first site. My problem here is when I search for any value that I/user entered and on the site, the site only refreshes and doesn't give me anything back but the empty option that i gave the site to display when there is no content to match the search. (That's not all of the Topic model) model.py class Topic(models.Model): content = models.CharField(max_length=200) views.py def search(request): query = request.GET.get('q') if query: result = Topic.objects.filter(content__icontains=query) context = { 'query': query, 'result': result} return render(request, 'learning_logs/topics.html', context) ( That's not all of the topics.html if it help to show all the page i can also put all of the code) topics.html {% block content %} <form method="GET" action="{% url 'learning_logs:search' %}"> {% csrf_token %} <input name="q" value="{{ request.GET.q }}" placeholder="search.."> <button class="btn btn-primary" type="submit"> Search</button> </form> {% for topic in topics %} ...... {% empty %} <h3><li>No topics have been added yet.</li></h3> {% endfor %} {% endblock content %} -
How can I remove folder's name and add www to domain on my .htaccess using .fcgi file?
I'm having trouble figuring out my .htaccess in a shared host for days now because I must keep the index.fcgi, otherwise my django project doesn't work. I'm trying to remove a folder named app from my URL and also make sure that when someone types www.domain.com it goes to my page. I already checked the CNAMEs from my domain and www.domain.com is there, but it doesn't go through with the pages inside my project, only if I type domain.com My .htaccess file: (I must keep the index.fcgi) AddHandler fcgid-script .fcgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.fcgi/$1 [QSA,L] My index.fcgi file: #!/usr/bin/scl enable rh-python35 -- /home/CONTA/.virtualenv/bin/python import os, sys from flup.server.fcgi import WSGIServer from django.core.wsgi import get_wsgi_application sys.path.insert(0, "/home/CONTA/mydjangoproject") os.environ['DJANGO_SETTINGS_MODULE'] = "mydjangoproject.settings" WSGIServer(get_wsgi_application()).run() Thanks a lot in advance! -
Validating access_token against Azure AD coming from ReactJS
The crux of all the below is this: how do I validate an Azure AD access_token from the Django/DRF API sent to it from the ReactJS FE? My web application is a microservice setup, so completely distinct services between the FE and API. The Django/DRF API serves no static assets and should only be accessible via the FE and the data it is authenticated to consume from it. I have the ReactJS FE successfully getting an access_token from Azure AD and my tenant using react-aad. (Note: This based on msal v1.0 which will be replaced by @azure/msal-react using msal v2.0 hopefully this month at some point). Now I just need to send it to the API where it is validated against Azure AD. This has been a real struggle finding something that works or that is documented well enough. I've tried the following, but ultimately hit this issue with all of them that I can't seem to figure out: social-auth-app-django django-rest-framework-social-oauth2 drf-social-oauth2 This article At any rate, can't get those working properly so now I'm playing with libraries developed by Microsoft: azure-activedirectory-library-for-python... I guess this is deprecated and the next one should be used. Not sure how this correlates to … -
question about "attributes" attribute of a class
This is probably a simple question but I'm wondering why it seems attribute names and values are reversed in the following example: >>> class SelectOne(DjangoChoices): ... cola = ChoiceItem("c", "Coca Cola") ... beer = ChoiceItem("b", "Heineken") ... >>> SelectOne <class 'SelectOne'> >>> SelectOne.attributes OrderedDict([('c', 'cola'), ('b', 'beer')]) >>> for k, v in SelectOne.attributes.items(): ... print (k, v) ... c cola b beer Common understanding should be that "cola" is the key and "c" is the value. where can I find the documentation of "attributes" attribute of a class? -

object_id in ContentType
I can't seem to find some explanation how to set the field object_id in either the documentation here or this very helpful post here. Since this field is compulsory, how is it set by Django during runtime? If I want to set it from within admin, what caution, if any, should I be taking? Is it supposed to be related to the pk of the related model somehow or is it purely a unique integer that I can just set? Thanks. -
Django Custom Permission method or decorator
I am many views and more than one user type. I want some views that can be seen by specific user types and other users cant see this.

Only Company can see this') # > rest of the logic return render(request, 'template.html') and above this working very well and solves my problem but i don't like this. coz, i don't want to write every time for the rest of the views for the company related views. So i am finding a solution so that i can use decorator or something else that are best practice Can anyone help me in this case? -

Modeling favorites in Django from two different models
I have a Netflix clone app that I am creating and I am having difficulty with the models. I have a Movie model that has fields for the movie such as a title, duration, rating, etc. I am not sure how I should model my database but what I believe I should be doing is a ManyToMany relationship, such as, a user can favorite many movies and a movie can be favorited by many users. However, if I do it like this I feel that I would end up with a Favorites table that would have many users and movies and possible see this as an issue having to go through each row to find the current user rather than doing maybe a OneToMany relationship, such as, a user can favorite many movies and a movie can be favorited by a user. So first, I am not sure what the proper way of modeling this would be. I also do not know how to add this relationship to my user model because I am using the User model that I brought in from django.contrib.auth.models I am having a lot of trouble trying to think of a solution for this and … -

Pulling data from Django database and populating lists for user input
I'd like to preface this with first - thank you for anyone willing to listen to my question - it may be a bit complex and second I'm very new to web development so I'm sorry if I sound dumb. I'm making a website that essentially allows admins (Professors) to input courses based on specific majors, and allows users (Students) to select what courses they've taken so far - and based on that input - display what courses they must still take to complete their degree. In the Django admin page - it allows admins to create courses offered and one of the parameters is the major affiliated with the specific course. I then want the users (Students) to be able to select one of the majors (there are nine) - and dependent on what major they select - choose from the available courses provided affiliated with that major. After the user selects what courses they've taken it would redirect them to a page that displays all the remaining courses they must take. My question is, how do I take the data inputted by the admins, and based on the major they provide - send that data to a major … -

Ranking system with ForeignKey in Django
I want to have ranking for university model. There can be several ranking types for each university. Admin should be able to add and delete the ranking type and score as needed. For example: Harvard will have 3 different rankings and different scores in those rankings. But X University will have none. But some other university can have totally different ranking type and more than three. Universities should be filterable according their score in each ranking type. I tried this: class University(models.Model): title = models.CharField(_("title"), max_length=250) about = models.CharField(_("about"), max_length=450) logo = models.CharField(_("logo"), max_length=150) ranking = models.ManyToManyField("program.Ranking") def __str__(self): return self.title class Meta: verbose_name_plural = 'Universities' class Ranking(models.Model): title = models.CharField(_("Title"), max_length=250) scope = models.ForeignKey("program.Scope", on_delete=models.DO_NOTHING) score = models.IntegerField(_("Score")) def __str__(self): return f'{self.title} {self.score}' class Scope(models.Model): title = models.CharField(_("Title"), max_length=350) def __str__(self): return self.title I see it as not well-optimized (because of repetitiveness) and think there should be better way of doing it. Is there better way of doing it? If yes, please add some code and give explanation why it is better idea than mine. -
