Hi every one
I have two model one for storing the product specification and the other for comments for products
what i want to do is to have a template that:
Yes it is possible
I’ll provide you some context data related to your query
# Models
class Product(Model):
....
@property
def get_comments(self):
product_comments = self.product_comments.all()
return product_comments
class ProductComments(Model):
product = models.ForeignKey(Product, on_delete=models.CASCADE, related_name="product_comments")
....
So what I did here is created two models as you can see and in ProductComments model there is a ForeignKey of product with related_name="product_comments". it is very important. Than in Product model there is a property method which will retrieve all the comments from ProductComments for a specific product.
You can use it in your template or even in your REST APIs.
thanks for your answer
now all comments displays in my template
one other thing i want to do in this template is having a form i by witch a user can leave a comment
actualy here is my views.py
class GoodsListView(DetailView):
model = Goods
template_name = 'goods_list.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['detail'] = Goods.objects.filter(id=self.kwargs['pk']).values()
context['comment'] = Comments.objects.filter(goods=self.kwargs['pk']).\
values('goods', 'customer', 'vote_text').order_by('customer')
context['customer'] = CustomUser.objects.filter(id__in=
Comments.objects.filter(goods=self.kwargs['pk']).values('customer'))\
.values('id', 'first_name', 'last_name').order_by('id')
context['goods_main_band'] = MainBranch.objects.filter(mb_code__in=
Goods.objects.filter(id=self.kwargs['pk']).values('goods_main_band_id')).values('main_desc')
context['goods_sub_band1'] = SubBranch1.objects.filter(sb1_code__in=
Goods.objects.filter(id=self.kwargs['pk']).values('goods_sub_band1_id')).values('sb1_desc')
context['goods_specification'] = GoodsSpecification.objects.filter(goods_sub_band2__in=
Goods.objects.filter(id=self.kwargs['pk']).values('goods_sub_band2_id')).values('spec_desc')
context['goods_properties'] = GoodsProperties.objects.filter(goods_sub_band2__in=
Goods.objects.filter(id=self.kwargs['pk']).values('goods_sub_band2_id'))\
.values('goods_intro', 'goods_criticize')
return context
class GoodsDetailView(LoginRequiredMixin, View):
def get(self, request, *args, **kwargs):
view = CommentGet.as_view()
return view(request, *args, **kwargs)
def post(self, request, *args, **kwargs):
view = CommentPost.as_view()
return view(request, *args, **kwargs)
class CommentGet(DetailView):
model = Comments
template_name = "goods_detail.html"
def get_object(self, queryset=None):
return Goods.objects.get(pk=self.kwargs.get('pk'))
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context["form"] = CommentForm()
return context
class CommentPost(SingleObjectMixin, FormView):
model = Comments
form_class = CommentForm
template_name = 'goods_detail.html'
def post(self, request, *args, **kwargs):
self.object = self.get_object()
return super().post(request, *args, **kwargs)
def form_valid(self, form):
comment = form.save(commit=False)
self.object = self.get_object()
comment.goods = self.object
comment.save()
return super().form_valid(form)
def get_success_url(self):
goods = self.get_object()
return reverse("goods_detail", kwargs={"pk": goods.pk})
and urls.py
urlpatterns = [
path('about/', AboutPageView.as_view(), name='about'),
path('?/', GoodsSearchView.as_view(), name='gsview'),
path('?/<int:pk>/', GoodsListView.as_view(), name='goods_list'),
path('?/<int:pk>/comment', GoodsDetailView.as_view(), name='goods_detail'),
]
i can reach new comment page by adding /comment at thr end of url but i want to display comment form in product page
which one of them is the view you are talking about ?
GoodsListView is the one
Okay so in your get_context_data method pass the form as well if you have created a comment form in your forms.py else continue to next part
Now from your template whenever you submit a form it will send form data to your view, for this you can use GoodsListView here just create a post method and handle every part in it.
class GoodsListView(DetailView):
.....
def post(self, request):
....
also in the template in your form tag use action as . i.e
<form method="post" action=".">
...
</form>
Thanks for your help it worked
Now i have another problem updating/deleting commens
i wrote update/delete view as follow but i get 'page not found ’ error
updateview
class CommentUpdate(UserPassesTestMixin, LoginRequiredMixin, UpdateView):
model = Comments
form_class = CommentForm
template_name = 'edit_comment.html'
fields = ['vote_text']
success_url = 'goods_list'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
self.object = self.get_object()
context['obj'] = self.object
context['form'] = CommentForm
return context
def test_func(self):
obj = self.get_object()
return obj.customer == self.request.user
delete view
class CommentDelete(UserPassesTestMixin, LoginRequiredMixin, DeleteView):
model = Comments
template_name = 'delete_comment.html'
def get_context_data(self, **kwargs):
context = super().get_context_data()
context['g_name'] = Goods.objects.filter(id=self.kwargs['pk']).values('name')
context['g_comment'] = Comments.objects.filter(goods=self.kwargs['pk']). \
values('vote_text').order_by('customer')
return context
def test_func(self):
obj = self.get_object()
return obj.customer == self.request.user
urls.py
from django.urls import path
from .views import GoodsSearchView, AboutPageView, GoodsListView, CommentUpdate, CommentDelete
urlpatterns = [
path('about/', AboutPageView.as_view(), name='about'),
path('?/', GoodsSearchView.as_view(), name='gsview'),
path('?/<int:pk>/', GoodsListView.as_view(), name='goods_list'),
path('?/<int:pk>/edit_comment/', CommentUpdate.as_view(), name='edit_comment'),
