Django read frame returning decimal fields value after rounding or truncating

Django-crispy-forms: set css for individual field and inputs
Is there a way to specify the css for an individual field and input in django crispy forms? I am using bootstrap4 and would like to use a horizontal form for a few fields in my form. I know you can use a self.helper to set label.class and field.class but I presume that applies to all field. I only want to change the label and field class on a few of my fields. -
What is the command to search a content in all the model fields at once?
I am developing an app with Django. I have developed a search bar to filter the database contents. I want that, when the user clicks on the search button, the indicated content is searched in all the model fields. My model has 16 fields, so my filter command will be a very long line, like: selected_entries = glossary_entry.objects.filter(Q(field1__icontains=query) | Q(field2__icontains=query)) | ...ETC ETC... | Q(field16__icontains=query)) Here you can see this line in my view function, in views.py: def glossario(request): query = request.GET.get('q') template = "glossario.html" # query applied if query: query = request.GET.get('q') selected_entries = glossary_entry.objects.filter(Q(field1__icontains=query) | Q(field2__icontains=query)) | ...ETC ETC... | Q(field16__icontains=query)) return render(request, template, {'all_entries':selected_entries}) # no query else: all_entries = glossary_entry.objects.all return render(request, template, {'all_entries':all_entries}) Is there a shorter command to do the same? Like: selected_entries = glossary_entry.objects.filter(Q(ALL_MODEL_FIELDS_ICONTAINS(model=MyModel)=query)) Note: ALL_MODEL_FIELDS_ICONTAINS is my invention -
How to display and save mutiple instances of a django form based on variable amount?
I've been looking around the site and can't seem to find an answer. Same for the django docs. The issue is I can't seem to save multiple instances of the same form. I'm trying to have a user set up a weekly calendar for a sports club. They land on a page with check boxes of each day they have activities. So if they click monday, tuesday, wednesday. Three instances of the DAY model are created created. Which works fine. Then, on the next page. Based on the amount of Days they have chosen, I would like a PeriodsForm (for this example let's just say they have one period each day). Then they can set what time each day starts and finises. I just can't seem to save the data. I was hoping someone has come across this before. Many thanks. I've tried using the modelformset_factory() but it's far too rigid. I also tried prefixes but I can't seem to loop through the forms on the POST. ### views.py def create_timetable_days(request): club = request.user.club form = TimetableCreateForm(request.POST or None) if len(list(Day.objects.filter(club=club))) > 0: return redirect('/timetables/create_timetable_times') if form.is_valid(): for item in form['Days']: if item.data['selected']: day = Day(name=item.data['label'], club=club) day.save() return redirect('/timetables/create_timetable_times') … -

How to allow tabulators when displaying string on website?
I pass the string named 'data' to a html page. With the following command i can generate linebreaks with '\n' in the string: {{ data | linebreaks}} The sting also contains tabs '\t' which are ignored and not displayed. So i look for some filter allowing tabs, something like: {{ data | linebreaks | tabulators}} But 'tabulators' is not a predefined filter. Does someone know what command i am looking for? -
Django Rest Framework - Group data by dynamic Key
I'm trying to format data when querying my API. I can retrieve my data like that : "results": [ { "Cat1": [ { "job": String, "position": Integer } ] }, { "Cat1": [ { "job": String, "position": Integer } ] }, { "Cat2": [ { "job": String, "position": Integer } ] } ] But I want something like that: "results": [ { "Cat1": [ { "job": String, "position": Integer }, { "job": String, "position": Integer } ] }, { "Cat2": [ { "job": String, "position": Integer } ] } ] I use a serializer like this: class CustomSerializer(serializers.ModelSerializer): cat = CatSerializer() job = JobSerializer() class Meta: model = MyModel fields = '__all__' def to_representation(self, value): return { value.cat.name: [{"job": value.job.name, "position": value.position, }] cat1 and cat2 are dynamics, they are from another table. I don't understand how to create my arrays properly using those serializers. The category is a @Property field in my model who's a foreign key of job. How should I deal with serializers to format my data properly ? -

Filter/order django rest api on a property=value but property is a value instead of a field
Consider an object that has multiple properties. class Object(models.Model): name= Charfield(max_length=80) class Property(models.Model): object= ForeignKey(Object, related_name='properties') name= Charfield(max_length=80) value= Charfield(max_length=80) I would like to provide an api accessible listview for the Object model, but I'm failing at ordering the ObjectList by property value as well as at sorting the the ObjectList by property value. To make the example more tangible you can imagine that Object has as type book, and an object of book has, among other properties, a property with name title and a value such as 20,000 Leagues Under the Sea. I would like to be able to be able to specify ?order_by=title and to be able to filter ?title__contains=League (or at least ?title="20,000 Leagues Under the Sea". I already did try to annotate Object with title="20,000 Leagues Under the Sea" and I'm able to show the title in the ObjectSerializer as if it was a field, but then ordering by this field does not work. -

Django channels daphne returns 200 status code
I have setup a Django application with Nginx + uwsgi. The application also uses django-channels with redis. When deploying the setup in an individual machine, everything works fine. But when I tried to setup the app in 2 instances and setup a common load balancer to coordinate the requests, the request get properly routed to the daphne process and I can see the logs. But the status code returned from the daphne process is 200 instead of 101.

How to filter by dictionary key using FilterSet of django tables2

What's the proper order in which Django cache middleware should be added?
I'm trying to add caching to my Django project and I'm failing to understand documentation on middleware ordering. Consider the following MIDDLEWARE list, which is mostly default: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'simple_history.middleware.HistoryRequestMiddleware' ] If I'm understanding this piece of documentation correctly, I'm supposed to add three new entries to MIDDLEWARE list. Is there more than one proper ordering for my case? -

m2m_changed when items added and removed
I'm wondering if it's possible to gather the 'end state' of a m2m field in Django? I'm currently using m2m_changed.connect(myfunction, sender=MyModel.tests.through) And I have: myfunction(**kwargs): action = kwargs.pop('action', None) instance = kwargs.pop('instance', None) if action in ["post_remove", "post_add"]: instance.owned_tests = instance.tests.count() instance.save() My problem is that if I add and remove items from the m2m field and then save, two m2m_changed signals are fired, one for the add, and one for the remove. Is there any way to group these together in order to only have myfunction called once when all changes to the m2m field are finished? -

I am developing a webapp in Django. I developed a nice search bar with two buttons. One of these (fa fa-search) is to search and display the results of the database, and it is altrady working. I would like that, when my user clicks on the other one (fa fa-trash), the code erases the query and reloads all the unfiltered results. How do I do it? Here is my code: in views.py: def glossario(request): query = request.GET.get('q') template = "glossario.html" # query apply if query: query = request.GET.get('q') #q è variabile risultante dalla query del database selected_entries = glossary_entry.objects.filter(Q(Lemma_it__icontains=query)) return render(request, template, {'all_entries':selected_entries}) # no query else: all_entries = glossary_entry.objects.all return render(request, template, {'all_entries':all_entries}) in glossario.html: <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"> <div class="topnav"> <a id="pulsante_ricerca_avanzata" href="#Ricerca_avanzata">Ricerca avanzata</a> <div id="blocco_ricerca_semplice" class="search-container"> <form method="GET" action="{% url 'glossario' %}"> <input type="text" placeholder="Ricerca terminologia..." name="q" value="{{request.GET.q}}"> <button id="cancel_search_button" type=""><i class="fa fa-trash"></i></button> <button id="search_button" type="submit"><i class="fa fa-search"></i></button> </form> </div> </div> -
Django fieldset.html override
So I decided to override all the Django templates for a custom look and feel for my WebApp. One problem I'm coming across though, is that I want to change the classes of these fields to form-control (I'm using bootstrap). I see that there's a built in function is_checkbox but there isn't anything to see if it is an input tag or a select tag. What I basically want to do is for Django to iterate over all the fields in the field set if a field is an input tag, I want to add the form-control class to it and if it is a select tag, I want to add the selectpicker class to it. Here's the Django code I'm referencing: <fieldset class="module aligned {{ fieldset.classes }}"> {% if fieldset.name %}<h2>{{ fieldset.name }}</h2>{% endif %} {% if fieldset.description %} <div class="description">{{ fieldset.description|safe }}</div> {% endif %} {% for line in fieldset %} <div class="form-row{% if line.fields|length_is:'1' and line.errors %} errors{% endif %}{% if not line.has_visible_field %} hidden{% endif %}{% for field in line %}{% if field.field.name %} field-{{ field.field.name }}{% endif %}{% endfor %}"> {% if line.fields|length_is:'1' %}{{ line.errors }}{% endif %} {% for field in line %} <div{% … -
I can't get the values from django dropzone into view
I have trouble getting the django Dropzonejs values of the chosen file into django. It just creates an empty file object in the models. The problem is that I can't get the values into the model. It just creates aa blank model. HTML: <form class="dropzone" action="{% url 'teacher_assignment_add_file' OBJECTID %}" method="POST"> {% csrf_token %} <div class="fallback"> <input name="Assignment-File" type="file" multiple /> </div> </form> <ul class="list-group list-group-activity dropzone-previews flex-column-reverse"> {% for file in files %} <li class="list-group-item"> <div class="media align-items-center"> <ul class="avatars"> <li> <div class="avatar bg-primary"> <i class="material-icons">insert_drive_file</i> </div> </li> </ul> <div class="media-body d-flex justify-content-between align-items-center"> <div> <a href="{% url 'file123' file %}" data-filter-by="text">{{ file }}</a> <br> </div> <div class="dropdown"> <button class="btn-options" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> <i class="material-icons">more_vert</i> </button> <div class="dropdown-menu dropdown-menu-right"> <a class="dropdown-item" href="#">Download</a> <a class="dropdown-item" href="#">Share</a> <div class="dropdown-divider"></div> <a class="dropdown-item text-danger" href="#">Delete</a> </div> </div> </div> </div> </li> {% endfor %} View: @login_required def teacher_assignment_add_files(request, assignment_id): if request.method == 'POST': file = request.POST.get('Assignment-File') file = File(file=file) file.save() assignment = Assignment(id=assignment_id) assignment.files.add(file.id) return redirect('teacher-detail-assignment', id = assignment_id)
