Angular 2 HTTP GET returning URL null, not a CORS issue
I have an Angular2 App running that is attempting to make a call to my Django server. I have a function called getOffreById That makes the external API call and should return a list of objects. However, i've tried fiddling with a few of the HTTP headers, as well as playing around with some settings on my server, but I cannot figure out what is wrong. Any help in the matter would be much appreciated, I can provide any additional debug information.

Django, 2.0.4 path is not work, how to fix?
Today for the first time installed the 2nd version of django and in shock from this shit, took and removed the normal routing using url I know that there is a re_path but this is not it! In general, everything was done according to the instructions as django, but it does not work does not see any coincidences! error Using the URLconf defined in src.urls, Django tried these URL patterns, in this order: admin/ / ^media\/(?P<path>.*)$ The empty path didn't match any of these.

Feed javascript parameter with django model value
I am working on a website with Django, and I want to include a 3D viewer (three.js) which read an object file selected by the user. So, I get all 3D objects files via a call from my Django model in the template: HTML body {% for 3dobj in 3dobj _list %} <li>{{ 3dobj.path}}</li> {% endfor %} And then, I would like that by selecting one object of my list, it will feed my javascript function with the path "/media/3D_object_1.obj" JS var onLoadMtl = function ( materials ) { objLoader.setModelName( modelName ); objLoader.setMaterials( materials ); objLoader.getLogger().setDebug( true ); objLoader.load( '/media/3D_object_1.obj', callbackOnLoad, null, null, null, false ); }; How could I do that ?

Django 2.0 URLs: Configuring urls.py file

Django Rest Framework list and detail view overlap
My API is going to list a bunch of episodes of a podcast. The list itself should be stripped down and not have a lot of data to be small enough to pull the whole list at once. Here's my DRF serializer class class EpisodeSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Episode fields = ('url', 'id', 'title', 'subtitle', 'show_id', 'published_at', 'updated_at') This works just fine using this view class EpisodeViewSet(viewsets.ModelViewSet): queryset = Episode.objects.all().order_by('-published_at') serializer_class = EpisodeSerializer The `HyperlinkedModelSerializer' also links the episodes to their own detail views but obviously uses the same view by default. Now what I want is to be more detailled on the detail view so what I did was: router.register(r'episodes', views.EpisodeViewSet) router.register(r'episode', views.EpisodeDetailViewSet) added this route and made a new view class EpisodeDetailViewSet(viewsets.ModelViewSet): queryset = Episode.objects.all().order_by('-published_at') serializer_class = EpisodeDetailSerializer and the serializer using additional models for more details class EpisodeDetailSerializer(serializers.ModelSerializer): chapters = ChapterMarkSerializer(source='chaptermark_set', many=True) media = MediaClipSerializer(source='mediaclip_set', many=True) show = ShowSerializer() class Meta: model = Episode fields = ('url', 'id', 'title', 'subtitle', 'show', 'published_at', 'updated_at','description', 'show_notes', 'cover_image', 'updated_at', 'chapters', 'media') depth = 1 Now this basically works for each Episode now using the /episode/123 format but it also renders all episodes with full details under the /episode URL … -

Django QuerySet FIlter based on previous QuerySet
This may be a simple answer but after days of searching I cannot seem to figure out the correct way to achieve this. I have a template where I want to show all the questions that are related to an assessment that has been assigned to a user. I thought that I could use the results from: ResponseDetails = AssessmentResponse.objects.prefetch_related('assessment').filter(id=response_id) by looking into the object and grabbing the assessment_id which I could then pass into the next query-set as a filter but I couldn't get that to work. Problem: Because the view doesn't filter based on the assessment_id found in the AssessmentResponse model, it gives me every question in the AssessmentQuestion model. An answer would allow me to actually have a good nights sleep trying to figure it out. Views def UpdateAssessmentResponse(request, response_id): ResponseDetails = AssessmentResponse.objects.prefetch_related('assessment').filter(id=response_id) QuestionList = AssessmentQuestion.objects.all() ChoiceList = AssessmentQuestionChoice.objects.all() context = { "ResponseDetails":ResponseDetails, "QuestionList":QuestionList, "ChoiceList": ChoiceList, #"ID" : ID, } return render(request, "assessment/assessment_response_update.html", context) Template {% if QuestionList and ResponseDetails%} {% csrf_token %} {% for question in QuestionList %} <p> {{ question.question_text }} </p> {% for choice in ChoiceList %} {% if choice.question_id == question.pk %} <fieldset id="group1"> <div class="custom-control custom-radio custom-control-inline"> <input type="radio" class="custom-control-input" name="choice" id="choice{{ … -

Iterating a dict->list->dict->list->dict data structure
I have a complex data structure which represent a n-dimensional dictionary of lists of dictionary of lists categories. And For every child I have to make an of the name of the category.

Is it possible to iterate it with Jinja2, or I have to pull of a good interpretation in the view? -
Making a CBV(CreateView) from django FBV with 2 models (Gangster/GangMember)
Hi Djangonauts I am new to Django please forgive any silly mistakes. Lets say I am trying to make this web-app that allows users to write about Gangsters (more like the post model)from around the world and from different time periods and I am trying to convert the below FBV to a CBV (CreateView) so I can have a easy to make (UpdateView) & (DeleteView). I am using 2 models in this post_create. Gangster and GangMember . Below is how the model looks models for Gangster class Gangster(models.Model): user = models.ForeignKey(User, related_name='posts') gangster_name = models.CharField(max_length=250, unique=True) slug = models.SlugField(allow_unicode=True, unique=True) history = models.TextField() gangster_image = models.ImageField() # there are more attributes like "Post-like but ignoring them as they are not relevant here" def save(self, *args, **kwargs): self.slug = slugify(self.title) #for SEO on google searches super().save(*args, **kwargs) Now there is a model called GangMember which is a Foreign-Key of Gangsters. A user can add from 0 to 7 GangMember to their Gangster post(you'd be surprised some gangmembers were more popular than the main boss, super-hot blondes, superbad hitmen). model for Gangmember class Gangmember(models.Model): gangster = models.ForeignKey(Gangster, on_delete=models.CASCADE, related_name="ganglord") gangmember_image= models.ImageField(upload_to='images/', blank=True, null=True, default='') gangmember_name = models.CharField(max_length=100, default='') brief_description = models.CharField(max_length=1000, default='') … -

Django Rest Framework relation Attribute error
I'm fighting to find my way into DRF and can't get related data into my endpoint. models.py class ChapterMark(models.Model): title = models.CharField(max_length=100, null=True) episode = models.ForeignKey(Episode, on_delete=models.CASCADE) start_time = models.CharField(max_length=20) class Episode(models.Model): title = models.CharField(max_length=100, blank=False) show = models.ForeignKey(Show, on_delete=models.PROTECT) serializers.py class ChapterMarkSerializer(serializers.ModelSerializer): class Meta: model = ChapterMark exclude = ('') class EpisodeSerializer(serializers.ModelSerializer): chapters = ChapterMarkSerializer(source='id') class Meta: model = Episode depth = 1 The error I'm getting is Got AttributeError when attempting to get a value for field start_time on serializer ChapterMarkSerializer. The serializer field might be named incorrectly and not match any attribute or key on the int instance. Original exception text was: 'int' object has no attribute 'start_time'. My guess is that the relation via source='id' just doesn't work but everything I found so far is pointing back to doing it that way. There's a many to one relationship between chapters and episodes (so each episode has many chapters). I'm sure I'm just missing an important part. -

Django Deferred Attribute operand error
I am getting the following error: unsupported operand type(s) for *: 'DeferredAttribute' and 'DeferredAttribute' in Django, when I am trying to use two variables as such: def MakeCalcs(a,b): varc = a*b return varC I think that this originates from the fact that when the model fields are being populated in sequence (i.e., a and b are being populated after the model already exits). My question is how do I use those model fields? is there some way to turn a deferred attribute into one that you can apply operations to? -
Django: Is there a way to address informally with "du"?
In contrast to English there are two different "versions" of how you can speak with others in German. You can use the formal, more impersonal "Sie" or the informal, more personal "du". So, while you just say "Can you help me?" in English, you could say Können Sie mir helfen? (formal, when you don't really know the person) Kannst du mir helfen? (informal, when you know the person already) in German. My problem now is that for my Django application I would like to use the second version ("du") because it just suits much better for my web application. Thing is that Django (what I know?) just supports the formal version and now I have inconsistencies in the web application. Sometimes, there you can read "du" and sometimes "Sie" (from the default Django translations). Of course, I could remove my manually added sentences with "du", but I do not like it because the web page will be for people who know each other. My two questions: Is there a way to let Django use the informal translation that I perhaps have missed? In case Django does not provide this feature, is there a way to let Django support it (I … -

How to pass django model field to function and have variables returned to context for use in template
I have some values that I collected from users in a form, which are saved to the DB. I want to take these values, perform an operation on them in function, and then return them so that I can use them in them alongside the other context. Here is my model: #models.py file class MyModel(models.Model): varA = models.PositiveIntegerField() varB = models.PositiveIntegerField() varC = models.PositiveIntegerField() And here is the outside function that I am using: #makecalc.py def MakeCalc(varA, varB, varC): #simplified from what I am actually doing varD = varA*varB**varC varE = varA+varB+varC return varD, varE And here is the views.py file: #views.py file from .makecalcs import MakeCalc class MySummary(DetailView): model = MyModel def get_vars(self): varD, varE = MakeCalcs(varA, varB, varC) #Am I passing this correctly? return varD, varE #How do I send these to context? And finally the html: <p> you input: {{MyModel.varA}}</p> <p> you input:{{MyModel.varB}}</p> <p> you input:{{MyModel.varC}}</p> <p> I output:{{varD}}</p> #how do I call this? <p> you input:{{varE}}</p> #how do I call this? So, my question is in the view, how do I add varD, varE to context so that I can use it alongside varA, varB, and varC from the model? -
Jinja2 Django Python groupby('attribute') custom sort of grouper
So I have a Jinja2 template that I am using with Django. I have set up a for loop that does a groupby('attribute'). Is there any way that I can do a custom sort of the grouper sets. Below is the template code. {% for group in data('attribute')|groupby('property') %} {{ group.grouper }} {% for item in group.list %} {{ item }} {% endfor %} {% endfor %} I would like to do something like: for group in data('attribute')|groupby('property')|CUSTOM ORDERING SCHEME GOES HERE I know that it is possible to do: for group in data('attribute')|groupby('property')|reverse So what I am thinking is maybe it is possible.
