Reverse for 'create_song' not found. 'create_song' is not a valid view function or pattern name
I have a Django project in which the page that should load to show the album that has just been added, does not. It should go to the primary key for that album (auto generated) with the reference: http://127.0.0.1:8000/music/1/ but instead gives the error: Reverse for 'create_song' not found. 'create_song' is not a valid view function or pattern name. A variant of the same problem, I assume, Is that when I click on the VIEW DETAILS BUTTON (shown below in the index.html) it doesn't load: <div class="caption"> <h2>{{ album.album_title }}</h2> <h4>{{ album.artist }}</h4> <!-- View Details --> <a href="{% url 'music:detail' album.id %}" class="btn btn-primary btn-sm" role="button">View Details</a> <!-- Delete Album --> <form action="#" method="post" style="display: inline;"> {% csrf_token %} <input type="hidden" name="album_id" value="{{ album.id }}" /> <button type="submit" class="btn btn-default btn-sm"> <span class="glyphicon glyphicon-trash"></span> </button> </form> The code for the various sections is below: music/templates/music/album_form.html <div class="row"> <div class="col-sm-12 col-md-7"> <div class="panel panel-default"> <div class="panel-body"> <form class="form-horizontal" action="" method="post" enctype="multipart/form-data"> {% csrf_token %} {% include 'music/form_template.html' %} <!-- how form fields and inputs are laid out--> <div class="form-group> <div class="col-sum-offset-2 col-sm-10"> <button type="submit" class="btn btn-success">Submit</button> </div> </div> </form> </div> </div> </div> </div> </div> {% endblock %} music/views.py from django.views … -
How to use active record as DTO to my business objects.
I struggle with this problem for a long time. I searched and searched the whole internet for solution but nothing was acceptable for me. We started a project which looked very simple in terms of business logic required, so I picked Django as a framework to make things easier. The problem got complex and maybe the implementation will be used in a much larger project so I want to decouple my business objects objects from activerecord and I want to use django only as a DB backend and something which uses my objects. The UI is already decoupled from the start, it only calls a REST API provided by the django backend. My problems with an example: I have a Request model which connected to many other models. This request contains some requirement specification related to networks. These networks are associated to a Cloud models. The networks under a cloud will be connected to the reservation which is generated from the request (currently they are connected to the request's nw descriptors to determine the configurations during queries). class Request(Model): ... # bunch_of_stuff_here class NetworkDescriptor(Model): request = ForeignKey(Request) configA = ... configB = ... class Cloud(Model): ... class Network(Model): cloud = … -
Trying to understand JSONField for django postgresql
I'm reading the docs on JSONField, a special postgresql field type. Since I intend to create a custom field that subclasses JSONField, with the added features of being able to convert my Lifts class: class Lifts(object): def __init__(self, series): for serie in series: if type(serie) != LiftSerie: raise TypeError("List passed to constructor should only contain LiftSerie objects") self.series = series class AbstractSerie(object): def __init__(self, activity, amount): self.activity_name = activity.name self.amount = amount def pre_json(self): """A dict that can easily be turned into json.""" pre_json = { self.activity_name: self.amount } return pre_json def __str__(self): return str(self.pre_json()) class LiftSerie(AbstractSerie): def __init__(self, lift, setlist): """ lift should be an instance of LiftActivity. setList is a list containing reps for each set that has been performed. """ if not (isinstance(setlist, collections.Sequence) and not isinstance(setlist, str)): raise TypeError("setlist has to behave as a list and can not be a string.") super().__init__(lift, setlist) I've read here that to_python() and from_db_value() are two methods on the Field class that are involved in loading values from the database and deserializing them. Also, in the docstring of the to_python() method on the Field class, it says that it should be overridden by subclasses. So, I looked in JSONField. Guess … -

Django serve file to download with CBV
I am trying to serve multiple files in a DetailView. This is the flow: user uploads some docx files in a folder named 'documents' using formsets. In this detailview the admin will be able to see the files and download them. models.py class Order(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL) created = models.DateTimeField(auto_now_add=True) number = models.CharField(max_length=100, unique=True) class OrderDoc(models.Model): order = models.ForeignKey(Order) language_source = models.ForeignKey(Language, default=None, null=True) file = models.FileField(upload_to='documents') views.py class OrderUpdateView(LoginRequiredMixin, UpdateView): template_name = 'core/admin_order_update.html' model = Order form_class = OrderForm success_url = reverse_lazy('core:admin_order_list') def get_context_data(self, **kwargs): context = super(OrderUpdateView, self).get_context_data(**kwargs) context['order_documents'] = OrderDoc.objects.filter(order__pk=self.kwargs['pk']) return context admin_order_update.html <form method="POST" action="" enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <button type="submit">Save</button> </form> {% for document in order_documents %} {{ document.file }} {% endfor %} Obviously here document.file shows just the path.

Django yearless ranges
I need to store start and ending dates to save holidays. I don't care about the year part of dates, as a holiday will repeat every year. Also I need to be able to query this dates to see if a random datetime is in the range. And even when I don't want years stored, the query must understand that a holiday can start in one year and end next year (i.e. Dec 25th to Jan 4th). Previously I was storing the dates as DateTimeFields, then iterating over each stored holiday and checking if a given target date was inside the dates range. This was made in Python and forced me to evaluate the QuerySets into lists and finally add the value using something like getattr(result, 'is_a_holiday', value) As performance issues have arise I want to move this into an annotation (so I can keep the queryset with select_related and prefetch_related data) and make the database (Postgresql) do the query part, but then I run into the problem that the database considers the year, and thus a date inside a holiday for this year is not considered inside a holiday the previous year or next year. I've already tried django-yearlessdate … -
Applying ckeditor to a textarea
I am trying to add the (inline) CKEditor 5 to an existing django project. I figured I would just use the normal form workflow and simply add the CKEditor to a textarea element inside a form, as via the documentation. <form enctype="multipart/form-data" action="{% url 'some_url' %}" method="post"> {% csrf_token %} {{ message_form.media }} {{ message_form.as_p }} <textarea id="something"></textarea> <input type="submit" value="Post message" class="button-bright button-static" /> </form> <script> InlineEditor .create( document.querySelector( '#something' ) ) .catch( error => { console.error( error ); } ); </script> When I add this to my template the textarea shows up with some of the ckeditor styling applied, and it also shows the inline texteditor, but with all of the buttons greyed out. The only thing I can do is type stuff in the textarea but literally nothing else. I can't use enters and I can't even delete anything I typed by pressing the backspace button either. -

Django Aggregation: Aggregate on relational queryset
Suppose I have following models, which store questions and options for those questions. P.S: I am just writing the basic code just to give you idea. class Question(models.Model): text = models.CharField() class Option(models.Model): text = models.CharField() class QuestionOption(models.Model): question = models.ForeignKey(Question) option = models.ForeignKey(Option) And then I have models which store user Feedback and Options selected for each Question in the Feedback survey. class Feedback(models.Model): full_name = models.CharField() cell_phone = models.CharField() created_at = models.DateTime() class FeedbackOption(models.Model): feedback = models.ForeignKey(Feedback, related_name='feedback_options') option = models.ForeignKey(QuestionOption) Every feedback will have lots of feedback option objects. Now I want to filter all the feedback whose feedback options contain specific QuestionOption object and then perform aggregate query where I am checking if that feedback's FeedbackOptions option text is 'boo' add count. Can i do this in one step, Something like this # lets say i want to filter all feedback with QuestionOption id 1 stats = Feedback.objects.filter(feedback_options__option=1).aggregate( boo=Count(Case(When(feedback_options__option__option__text='boo', then=1))), hoo=Count(Case(When(feedback_options__option__option__text='hoo', then=1)))) It looks like it's applying aggregate on the only feedback option where option id is 1 not the rest of the feedback options for each feedback. -

The django-celery project is based on a virtualenv python3.x,and I had make it well at nginx,uwsgi,mariadb. At least,I think so for no error happend. I try to use supervisor to control the django-celery's worker,like below: command=env/bin/python project/manage.py celeryd -l INFO -n worker_%(process_num)s numprocs=4 process_name=projects_worker_%(process_num)s stdout_logfile=logfile.log etderr_logfile=logfile_err.log Also had make setting about celery events,celery beat,this part is well ,no error happend. Error comes from the part of worker. When I keep the proces big than 1,it would run at first,when I do supervisorctl status,all are running. But when I do the same command to see status once more times,some process status change to starting. So I try more times,I found that:the worker's status would always change from running to starting and then changeing starting to running-- no stop. When I check the supervisor's logfile at tmp/supervisor.log,it shows like: exit status 1; not expected entered runnging state,process has stayed up for > than 1 seconds(startsecs) 'project_worker_0' with pid 2284 Maybe it shows why the worker change status all the time.

Djanog save a model in admin.py
I need to save a parameter(specs which is a dictionary) in Estimate model in django's admin.py. Earlier I used signals but that did not appear to be a wise option. I have below admin.py and here I want to update Estimate's specs field by merging this field with Environment's specs. How can I achieve that? I am still learning Django. I have understood that in the Django admin, when I deal with Estimate model, I get response from Estimate and EstimateAdmin class. At the same time I also have Environment whose foreign key is Estimate and in the Django Admin's Estimate model, Environment is an object. I tried Estimate_specs = Estimate.objects.all() but need to filter the specs on the basis of current estimate and Environment_specs = Environment.objects.all() but again this needs to be filtered with specs on the basis of current estimate. I am not able to figure out how to get this working. class EnvironmentInlineAdmin (admin.TabularInline): model = Environment ... class EstimateAdmin (CommonAdmin): ... admin.site.register(Estimate,EstimateAdmin) class EnvironmentDetailsInlineForm(forms.ModelForm): class Meta: model = EnvironmentDetail fields = ['item_name','qty'] show_change_link = True class AddEnvironmentDetailsInlineForm(forms.ModelForm): ... class EnvironmentDetailsInlineAdmin (admin.TabularInline): ... class AddEnvironmentDetailsInlineAdmin (admin.TabularInline): model = EnvironmentDetail fields = ('item_name','item', 'qty', ) form = AddEnvironmentDetailsInlineForm … -
