Could not parse the remainder: '[loop.index0]' from 'query_results_course_id[loop.index0]'
I have used django to develop a web app. In frontend, I want to access the object through the loop like in the html template. <label class="radio-inline"> {% for course_for_select in query_results_2 %} <input type="checkbox" name="course_select" value="{{course_for_select}}">&nbsp; {{course_for_select}} {{ query_results_course_id[loop.index0] }} <br> {% endfor %} </label> However, error occurs: Could not parse the remainder: '[loop.index0]' from 'query_results_course_id[loop.index0]' -
Django date format by an user
I'm writing a Django application that requered to give the user the ability to create his own time format, over an API (problay GraphQl). I've figure out the following way, but it seems to be really hard solution for relativlly small problem. class Formatter(models.Model): ... class DateLetter(models.Model): formatter = models.ForeignKey(Formatter, related_name="letters", on_delete=models.CASCADE) index = models.IntegerField(db_index=True) letter = models.CharField(max_length=255, unique=True, choices=LetterChoices.CHOICES, default=LetterChoices.Y) And after that, just going with some sort of loop to get the instance as a date format (%Y-%m-%d) etc. -
Django multiple user roles using AbstractUser without username field
I am trying to build an electronic information system for one teacher and students. Using the tutorial shown here: https://simpleisbetterthancomplex.com/tutorial/2018/01/18/how-to-implement-multiple-user-types-with-django.html , in my models.py I have implemented the student and teacher models this way: class User(AbstractUser): is_student = models.BooleanField(default=False) is_teacher = models.BooleanField(default=False) class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) f_name = models.CharField(max_length=20) l_name = models.CharField(max_length=30) parent_tel_numb = models.CharField(max_length=13) parent_f_name = models.CharField(max_length=20) parent_patronimic = models.CharField(max_length=30) parent_l_name = models.CharField(max_length=30) group = models.ForeignKey(Group, to_field='id', on_delete=models.SET_NULL, blank=True, null=True) class Teacher(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) For my application I would like to exclude the username field both for Teacher and Student models. Instead, I want to use email as username. I have previously tried to do it this way, modifying the User model: class User(AbstractUser): is_student = models.BooleanField(default=False) is_teacher = models.BooleanField(default=False) username = None email = models.EmailField(unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] However, after that, when I tried to create a superuser in the terminal, the username field was omitted during the creation of superuser and after submission of email and password, I got an error, saying the username field is absent. How do I deal with this issue? -

Add wordlist.txt in exclude query
I am building a BlogApp and I am trying to add wordlist.txt at the place of exclude('wordlist.txt') What i am trying to do :- I build a feature of exclude posts according to words, For Example :- If a post contains word "Bad" then exclude that post like :- from django.db.models import Q posts = Post.objects.exclude(Q(description__contains='bad') & Q(description__contains='bad1')) BUT i am trying to exclude hundreds of words at the same time AND when i add all of them in this way then it will be very lengthy AND i don't want that, So i think I can make a file named wordlist.txt and put all my words that i want to exclude then put the path of wordlist.txt in exclude query so i do not have to write lengthy exlcude words in the query. For example :- posts = Post.objects.exclude(description__contains=wordlist.txt) ( Above example is just to explain, what i am trying to do ) I have no idea how can i do it . Any help would be Appreciated. Thank You in Advance -

Bulk update with different values in django 1.11
I have been reading the official documentacion of django 1.11 about bulk updating. My problem is that I have only seen how to update the fields for ALL the query objects. What I need is a bulk update but with different values, depending on a condition. Let me write an example. Let's say I have the following model: class A(models.Model): key = models.ForeignKey(SomeOtherModel, db_index=True) value = models.FloatField(blank=True, null=True, default=None) As you can see, the field_definition points to another model. What I want is to mass update the objects of a query of the model A based on that value. Something like this: A.objects.filter(key__id__in=[1,2,3]).update(value_for_id_1="1", ..., value_for_id_n="n") The only thing I have seen so for is this syntax: A.objects.filter(key__id__in=[1,2,3]).update(value="1") Any idea if this is even possible? How can I make this query efficient? -
The best way to get data from another database and refresh it every few seconds in Django
I am wondering what is the best way to get data from another database (on the same server but it is part of different application) and refresh it every few seconds. I want to let user to choose from a select form that contains all the objects with specific status field. I want to use pyodbc (I'm using MySQL for both of databases), run a simple select (E.g. SELECT Index, Name FROM Table WHERE Status = 'OPEN'), create object for every row if it doesn't already exist in Django database: cursor.execute("SELECT Index, Name FROM Table WHERE Status = 'OPEN") for row in cursor: try: order = Order.objects.get(index=row[0]) except Order.DoesNotExist: Order.objects.create(index=row[0], name=row[1]) but my question is- when should i run it? Time it in a loop and do it every few seconds somehow? Or should I just do it every time user requests for a view with select form that contains these objects. What is the correct approach? -

running some Dash-Plotly apps inside a Django app similar to PaaS (platform as a service)
I have a challenge and I would be grateful if you could give me some clue... I want to run some Dash-Plotly (a framework based on Flask) applications inside a Django app. I know Dash has a framework called django-plotly-dash but what I want is a Django app that our developed Dash(aka Flask) apps can easily be imported and run. In other words, I want to make Django app a Paas (Platform as a Service) and other Dash/Flask apps can be imported in Django dashboard/(our developed page) and can be accessible from the Django app. Some idea may be using Docker containers but is also has some challenges and we want to seek the most optimal solution. is there any idea??? -

How to return back just queryset objects from middleware?
I'm not sure being I understand what does Middleware will help me in Django do. but if it will help me to make some help for request/response to appear globally so that, I really need it. based on that, I read a little bit more explanations and tutorials about Middleware also, I read some docs in Django middleware hence, wanted to use a request which will return an object from query set based on this request something like you will see underneath: Order.objects.get(user=request.user, in_progress=True) I confused between the two next function names which handle the response in Middleware of Django: process_template_response and process_response the problem is I need to return back the objects which will be handled in the views.py file in Django by one of these response function. I read an old doc that supports Django 1.8 and see the difference between that two functions in response as following: the process_template_response as the documentation mentioned: is called just after the view has finished executing, if the response instance has a render() method, indicating that it is a TemplateResponse or equivalent. but when I read about process_response despite is called it before request as I understand, I figured out that … -

Django add custom permission
I am facing the problem of adding custom permission in Django. My idea is that when authorizing a user, if it belongs to group1, only the rows of group1 are displayed, and otherwise the rows of group2. There is a group field in the database table, it contains only two values group1 and group2. In the admin panel, I created 2 groups, respectively, and also included users in these groups. Also I created permissions and assigned them to each user. My models.py class Employee(models.Model): DEPT =( ('Group1', 'Group1'), ('Group2', 'Group2') ) dept = models.CharField(max_length=100, choices=DEPT, default='') fio = models.CharField(max_length = 100) work_place = models.CharField(max_length = 150, default= '') def __str__(self): return self.fio class Meta: permissions = ( ("view_museum", "can view museum"), ("view_ssoismi", "can view ssoismi"), ) My views.py def employee_list(request): context = {'employee_list': Employee.objects.all()} return render(request, "employee_register/employee_list.html", context) If i change the context row to context = {'employee_list': Employee.objects.filter(dept="Group1")} I get the desired result, but how can do it automatically with django groups and etc. Maybe i do something wrong? Any idea what to do next? Thanks in advance -
How to add multiple json entries/items into JsonResponse in Django?
When there is only one item, the below works: data = { "Id": item.id, "Title": item.title } return JsonResponse(data) When there are multiple items, how to compose the response json? for item in items: ... here is code to compose json including multiple items ... ... ... ... ... return JsonResponse(data) The json data would look like: { "items":[ { "Id":1, "Title":"aaa" }, { "Id":5, "Title":"fahldafs" }, { "Id":17, "Title":"ajjda" } ] } -
Problem with pluralization of translations in Django
Hello I'm trying to pluralize the following text <p>{% trans "How much apples do I have? I have " %} {{ nb_apples }} {% blocktrans count nb_apples=1 %}apple{% plural %}apples{% endblocktrans %}</p> My .po file is defined like that #: .\templates\pages\home.html:13 msgid "apple" msgid_plural "apples" msgstr[0] "pomme" msgstr[1] "pommes" But the above doesn't work. With count nb_apples=1 or count nb_apples=0 it never pluralize With count nb_apples>1 it produces a syntax error With count nb_apples=1|length it always pluralizes but the singular is not respected when I only get one apple. Notice that the nb_apples variable is randomly passed from the view like that def get_context_data(self, **kwargs): posts = Post.objects.all() context = super().get_context_data(**kwargs) context['title'] = _('Home') context['comment'] = _('Welcome to my site') context['posts'] = posts context['nb_apples'] = random.randint(1,10) return context and that, after the class def home(request): nb_apples = random.randint(1,10) return render(request, 'pages/home.html', { 'title': _('Home'), 'comment': _('Welcome to my site'), 'nb_apples': nb_apples }) I want to see "apple" or "pomme" when the nb_apples variable is equal to 1 and "apples" or "pommes" when the nb_apples variable is greater than 1. What's wrong?
