Prepopulate Values of Edit Form from Table Selection
I am trying to create an Edit for that allows the user to scroll through a table and click a button existing in each row to edit the data within a modal. The issue that I am running into is when I try to prepopulate the form with the existing values. How would I convert the EditCommunicationsForm below to display the current values of the row that you selected edit for? I know I can make the initial value a default value like "Testing" but I am not quite sure how to tell it to say "grab the project field from the row that you selected" What I want to do is ID = {{ communications.id }} for my table, but obviously that's wrong since it's half HTML. I need some sort of variable to change that definition for each row views def communications(request): comms_list = Communications.objects.order_by('id') if request.method == "POST": new_form = CommunicationsForm(request.POST, request.FILES) edit_form = EditCommunicationsForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect('http://127.0.0.1:7000/polls/communications/',{"new_form":new_form,"edit_form":edit_form,'comms_list':comms_list}) else: comms = Communications.objects.get(id=1) new_form = CommunicationsForm() edit_form = EditCommunicationsForm(instance=comms) query = request.GET.get('search') if query: postresult = Communications.objects.filter(id__contains=query) comms_list = postresult else: comms_list = Communications.objects.order_by('id') return render(request,'polls/communications.html',{"new_form":new_form,"edit_form":edit_form,'comms_list':comms_list}) forms class CommunicationsForm(forms.ModelForm): class Meta: model = Communications fields … -

Increase performance with prefetch and select related
I'm trying to export a csv with information from the model order which has a relation 1 to 1 with delivery channel and restaurant and a 1 to many relationship with orderlines. It is taking way too much time for download it (around 20 seconds for 10k lines). This is my code: orderlines = OrderLine.objects.select_related("product").only( "product__display_name", "quantity", "paid_amount", "discount_amount" ) return ( Order.objects.prefetch_related(Prefetch("orderlines", queryset=orderlines, to_attr="orderlines_list")) .select_related("delivery_channel") .select_related("restaurant") ) I thought about using only in the end but I can't use it on orderlines as it is a 1 to many relationship. I'm stuck on how to improve the performance. Many thanks. -

Django get values from field after order_by
I am trying to get the shared values from a field after ordering my model based on one of its fields. So for example I have a model named Course: class Course(models.Model): code = models.CharField(max_length=100) university = models.CharField(max_length=100) instructor = models.CharField(max_length=100) and then for ordering based on instructor I do: Course.objects.all().order_by('instructor').distinct('instructor') Which will then give me for example ABC123, Uni1, Adamson EFG456, Uni1, Adamson HIJ789, Uni1, James KLM321, Uni1, James How can I retrieve the results as a dictionary with the keys being the instructor and the value being a query set of model object? So I will get something such as: result = { "Adamson":<QuerySet[]>, "James":<QuerySet[]> } I cannot find an aggregate function that does this is there any way to do this using a single method? -

configuring the urls.py gives problem in the url generation

I am making a blog posting site in Django. When users post something it looks great if the title of the post has 21 characters. If the title for instance has 35 characters it moves the author, date and thumbnail to the right and if less than 21 it moves it to the left. I don't want this scenario to happen! This is how it currently looks The HTML code {% for post in posts %} <div class="blogpost"> <a class="post-title"> {{post.title}} </a> <img class="thumbnail" src="{{post.author.imageURL}}"> <a class="date-author">{{post.date}} - {{post.author}}</a> <br> <hr> <br> <div class="blogpost-content">{{post.context|linebreaks}}</div> <br> <br> <br> </div> <br> {% endfor %} The CSS code .blogpost { /*Whole blogpost div*/ border: 5px solid #149414; background-color: black; color: #149414; width: 700px; margin:auto; border-radius: 40px; border-width: 1px; } hr{ /*The middle line in the blogpost*/ height: 1px; background-color: #149414; border: none; } .thumbnail{ /*The author's image of the blogpost*/ height: 120px; width: 120px; position: relative; right: -70px; bottom: 4px; border: 3px solid #149414; border-radius: 50%; } .blogpost-content{ /*Content in the blogpost*/ text-align: left; margin-left: 30px; margin-right: 30px; } .date-author{ /*The date and author div in the blogpost*/ font-size: 12; margin:10%; } .green_link{ /*Green link to the random key*/ color:#149414; } .post-title{ font-size: … -
Creating a like button in django social media network
I'm new to django and I'm trying to create a like button for my blog posts. In my HomeFeed app However, I received this error when i click on the like button that i have created: ValueError invalid literal for int() with base 10: I am given a pointer that the problem comes from this statement: post = get_object_or_404(BlogPost, id=request.POST.get('blog_post_slug')) Is it because they are expecting all integers in the url but it is getting character values? I am unsure of how to change it and have tried for multiple hours. Views.py def LikeView(request, slug): context = {} post = get_object_or_404(BlogPost, id=request.POST.get('blog_post_slug')) if post.likes.filter(id=request.user.id).exists(): post.likes.remove(request.user) else: post.likes.add(request.user) return HttpResponseRedirect(reverse('HomeFeed:detail',args=[str(BlogPost.slug)])) def detail_blog_view(request, slug): context = {} #need to import a package get_object_or_404. return object or throw 404 blog_post = get_object_or_404(BlogPost, slug=slug) total_likes = blog_post.total_likes() context['blog_post'] = blog_post context['total_likes'] = total_likes return render(request, 'HomeFeed/detail_blog.html', context) models.py class BlogPost(models.Model): chief_title = models.CharField(max_length=50, null=False, blank=False) body = models.TextField(max_length=5000, null=False, blank=False) likes = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='blog_posts', blank=True) slug = models.SlugField(blank=True, unique=True) def __str__(self): return self.chief_title def total_likes(self): return self.likes.count() urls.py from .views import( detail_blog_view, LikeView, ) urlpatterns = [ path('<slug>/detail/', detail_blog_view, name= "detail"), path('<slug>/edit/', edit_blog_view, name= "edit"), path('<slug>/like/', LikeView, name='like_post'), ] detail_blog.html <form action="{% url 'HomeFeed:like_post' … -
How to have a model field be based on another models fields?
Relatively new to Django. I think what I'm trying to do is very simple but I've never done this before. "irrelevant2" is an attribute in my class "one" that I want to refer to a direct element in the class "two" (this part is working fine). Additionally, I want there to be a field called RELEVANT_VARIABLE in my class "one" that is essentially a dropdown menu that chooses between two elements of the class "two" and can only pick one. I understand that I need a form but so far have not been successful. My hunch says RELEVANT_VARIABLE should be a ForeignKey but I'm not sure how to attach it to a dropdown of either attr1 or attr2 from class "two". class two(models.Model): attr1 = models.CharField(max_length=100) attr2 = models.CharField(max_length=100) class one(models.Model): irrelevant1 = models.ForeignKey(Account, on_delete=models.SET_NULL, null=True) irrelevant2 = models.ForeignKey(two, on_delete=models.CASCADE) RELEVANT_VARIABLE = models.ManyToManyField(two, related_name="team_selection") And then in forms.py class OneForm(forms.Form): def __init__(self, *args, **kwargs): super(OneForm, self).__init__(*args, **kwargs) self.fields[**not sure what to even put here**] = forms.ChoiceField( choices=[(o[**not sure**], str(o[**not sure**])) for o in Two.objects.filter(irrelevant2=self)] ) class Meta: model = two
