How to search for the object of a foreign key django
I am creating an Task Completion Queue where people create Projects then add Posts to that specific Project, kind of like comments on a blog post. I am creating a detail view for the Project model, and I want to search all of the posts using the Project as a parameter because I only want posts that pertain to that specific Project. The problem is I cant figure out how to use the model currently being used as a search parameter in a Detail view Here's my models.py class MyProjects(models.Model): title = models.CharField(max_length=30) description = models.CharField(max_length=140) class Post(models.Model): title = models.CharField(max_length=50) content = models.TextField() project = models.ForeignKey(MyProjects, on_delete=models.CASCADE, null=True, default=None) And here is my views.py class ProjectView(DetailView): model = MyProjects def get_context_data(self, **kwargs): CurrentProject = get_object_or_404(MyProjects, title=self.kwargs['MyProjects']) completed = Post.objects.filter(status='Completed', project= CurrentProject) inProgress = Post.objects.filter(status='InProgress', project= CurrentProject) posts = Post.objects.filter(project= CurrentProject) Features = Post.objects.filter(ticket_type='Features', project= CurrentProject) context = super().get_context_data(**kwargs) context['posts '] = posts context['Features '] = Features context['completed '] = completed context['inProgress '] = inProgress context['projects'] = projects return context -

How to pass in value from a text box to this function and have it print the output out on html page?
So basically I have a text box and button and I want to be able to enter text into the textbox which will pass to the text to the WebOutput object and then I want to print those results from the function to the HTML page. Is this possible? Here is some code to get a better understanding. The function that I want to be able to pass in my text from the textbox to.

access file from static folder with template tags inside javascript code
appreciate if anyone can help. I have a app which creates file location from submit button - json_path = os.path.join('json', request.POST['submit'], '.json' ) This gives the file location under \static\json\ folder.

django + jquery Ajax + CORS = empty JSON response sent to server
I'm running my webapp on another domain via an iframe. This page can produce ajax POST called to the db. When these happen, the variables that I'm passing to the view that processes the ajax arrive empty (or not at all). When I run the ajax call, there are no errors. In other words, I don't beleive this is related to Csrf token as I'm passing that into the ajax view. I was previously getting errors related to the CSFR token, but I think I've resolved that. No, the ajax view just fails silently by not passing the required data back to the server. In trying to get this setup, I've done the following: 1) I'm including the csrf_token on the data I'm sending to my backend via ajax. 'csrfmiddlewaretoken': '{{ csrf_token }}', 2) I've installed django-cors-headers and set CORS_ORIGIN_ALLOW_ALL = True in settings.py 3) I've set CSRF_COOKIE_SAMESITE = None in settings.py 4) I've got the following standard code to support ajax requests $(document).ready(function(){ function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie !== '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); // Does this cookie … -
How to setup Django every time you use it? (i.e. using **source bin/activate** and ** python manage.py runserver**)

Preventing users writing foul language in the comment section
I don't want users to be able publish offensive comments on my posts. I know a way of censoring out s***, f***, c*** etc. But if you apply a blanket ban to offensive words then you may unintentionally end up banning a word such as Scunthorpe (a place in the UK) because it contains an offensive substring. In forms.py I want to set the comment active property to false if the comment potentially contains an offensive word. Therefore I could manually check any potentially controversial posts. models.py class Comment(models.Model): #The foreign key is linked to the ID field in the Post model #id = models.IntegerField(primary_key=True, blank=False) post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name='comments') nameid = models.ForeignKey(User,on_delete=models.CASCADE,related_name='commentsid') name = models.CharField(max_length=80) email = models.EmailField() body = models.TextField() created_on= models.DateTimeField(default = timezone.now()) active = models.BooleanField(default=True) forms.py I have tried setting active to false in at least 4 different ways but have so far had no luck. Does anyone have any suggestions? def clean_body(self): body = self.cleaned_data.get("body") if "f***" in body or "s***" in body : self.data['active'] = False self.fields['active'].initial = False self.cleaned_data.get("active")=False form.fields['active'].initial = False return body -

AttributeError: module 'pages.views' has no attribute 'home_view'
I was following a beginner's Django tutorial word-for-word creating a project called 'Pages' when all of a sudden my computer gave me an error (AttributeError) when I tried to access the localhost page (http://127.0.0.1:8000/) that was supposed to say 'Hello World.' Instead of seeing the statement, a 'This site can’t be reached' page was there. I am completely confused as to why this happened because I was following the instructor word-for-word yet got a different result. If anyone can help that would be very much appreciated! Here are my files views.py from django.http import HttpResponse from django.shortcuts import render # Create your views here. def home_view(*args, **kwargs): # args, kwargs return HttpResponse("<h1>Hello World</h1>") # string of HTML code urls.py """trydjango URL Configuration The `urlpatterns` list routes URLs to views.

Cross origin ajax requests with iframe resulting in 403 error
I'm attempting to run my webapp on another domain via an iframe. I'm using jquery ajax POST requests to my server with this webapp. I'm getting the following error: Forbidden (403) CSRF verification failed. Request aborted. So far, I've taken the following steps: 1) I'm including the csrf_token on the data I'm sending to my backend via ajax. 'csrfmiddlewaretoken': '{{ csrf_token }}', 2) I've installed django-cors-headers and: - added the middleware to the top of my list of middleware ('corsheaders.middleware.CorsMiddleware',), - added 'corsheaders' to the list of installed apps - set the following variable in my settings: CORS_ORIGIN_ALLOW_ALL = True 3) I've got the following code running to support ajax requests $(document).ready(function(){ function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie !== '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) === (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } var csrftoken = getCookie('csrftoken'); function csrfSafeMethod(method) { // these HTTP methods do not require CSRF protection return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } $.ajaxSetup({ beforeSend: function(xhr, settings) …
