For a query set of a single element, indexing 0th element of a (query_set[0]) and and query_set.first() give different values - Django 2.2.7
I am running this code: city_state_location = ( Location.objects.filter(city=city, state=state) .values_list("city") .annotate(long=Avg("longitude"), lat=Avg("latitude")) ) print( city_state_location, city_state_location[0], city_state_location.first(), len(city_state_location), ) Which outputs: <QuerySet [('New York', -73.9422666666667, 40.8382)]> ('New York', -73.9422666666667, 40.8382) ('New York', -73.9501, 40.8252) 1 Why does this happen? The query set only contains one element so I'm confused why indexing the first element is any different then calling .first() This is running on Django 2.2.7 -

Django - How to iterate comlicated JSON object?
I have json object like [{'Group Name': 'asdfasdf', 'inputs': [{'DataType': 'data2', 'DataName': 'asdfasdf'}, {'DataType': 'data1', 'DataName': 'asdfasd'}, {'DataType': 'data2', 'DataName': 'asdfas'}]}, {'Group Name': 'asdfasdf', 'inputs': [{'DataType': '', 'DataName': 'asdfasdf'}]}] Data type and data name fields can be multiple in one group name. Group name can be multiple with at least one data type and data name field. This multiplication is dynamical due to user's choice. However, I am new in python and django. I didn't understand loop mechanism of them. How can I build a loop mechanism for group name count and data inputs count? -
How to run a function in django within a specified time?

When I run the code blocks I mentioned above, although the celery states that the relevant function has been received, I can't see anything in the django admin Celery Result section and at the same time, the celery task does not work even if the specified time has passed. Also, when I give apply_async ' args=[id] with @shared_task(bind=True), set_firsat_urunu gives an error because you gave 2 parameters but it takes only 1. -
widgets for ChoiceField in modelform
I'm using a modelform for my form Post and I'm using a bootstrap starter code as my base.html but because I use the {% csrf_token %} {{form.as_p}} on my add_blog page, bootstrap doesn't work and because of that it needs class='form-control', I have managed to do that on all of my fields but Choice input, if I do include my author(choicefield) in the widgets I get a TypeError: init() got an unexpected keyword argument 'attrs' class PostForm(forms.ModelForm): class Meta: model = Post fields = ("title", "title_tag", "author", "body") widget = forms.Select(attrs={"class": "form-control"}) widgets = { 'title': TextInput(attrs={'class': 'form-control'}), 'title_tag': TextInput(attrs={'class': 'form-control'}), 'body': Textarea(attrs={'class': 'form-control'}), 'author': ChoiceField(attrs={'class': 'form-control'}) } -
Creating a simple form using django and searching a SQL database
I am trying to create a form that will allow users to search a database. The intended language is django. I have created the backend database for a simple student schema, and I will eventually have a stored procedure that takes different parameters, if any of the parameters are provided a search will be done on the database and results returned. For the purposes of this exercise, a simple table will also suffice for searching. I did some reading up and I have been able to come up with the below, however it feels like a log way from what I am trying to achieve, a prototype can be seen below of what I am trying to achieve. The back end database is SQL server, I have configured the database with django and created the table/tables. I would also like to understand how to play with stylesheets to create nice looking yet simple pages. On my views.py. This is what I have. from django.shortcuts import render from reporting_project.models import sqldbconnection import pyodbc def connsql(request): conn=pyodbc.connect('Driver={sql server};' 'server=localhost\DEV2;' 'Database=django_reporting;' 'Trusted_connection=yes;') cursor = conn.cursor() cursor.execute("select student_id, firstname, lastname, fullname, gender , enrollment_date from tbl_students") result = cursor.fetchall() return render(request, 'index.html',{'sqldbconnection':result}) if 'searchfield' … -

Accessing the values of a ManyToManyField in Django
I've created a Many to Many relationship in my project like this: class CustomUser(AbstractBaseUser, PermissionsMixin): email = models.EmailField(_('Email Address'), unique=True) user_name = models.CharField(_('User Name'), max_length=150, unique=True) # and a lot of other fields and stuff class Course(models.Model): user = models.ManyToManyField(CustomUser, related_name="enrollments", blank=True, null=True) course_name = models.CharField(_("Course Name"), max_length=200) In Django Admin site, I created some courses and added users to it. What I need is to get a list of courses that a unique user is enrolled and a list of users enrolled in a unique course. I know that I can access the Related Manager like this: user.enrollments <django.db.models.fields.related_descriptors.create_forward_many_to_many_manager.<locals>.ManyRelatedManager object at 0x7f4df159c0a0> And I know also that I can access the intermediate m2m class using: user.enrollments.through <class 'core.models.Course_user'> What I could not get (or find in the docs or even in internet at all) is how I can access the values contained in this relation (courses a user is enrolled and users enrolled in a course). Any help will be appreciated. -

How to ensure sending ajax request happen after mouseevents?
I track mouse movement on several elements on an HTML page. I used this [question][1] for the mouse movement function. Then I send how much a user spent over an element using an ajax POST request to a Django view which save it into the db every time there is a new movement. Now I am able to do that, except I noticed that every now and then one of the elements store the time stamp rather than how many seconds. it seems that js is messing up the calculation here: mouseoverTime = currentTime.getTime() - mouseenterTime; it seems that mouseenterTime doesn't get updated with the mouseenter event and remains zero, hence mouseoverTime becomes currentTime.getTime() I am confused because this doesn't happen all the time and I am not getting any errors. could that be because of a problem when the page is loaded? or do I need to put the mouseenterTime variable inside the function? here is my js code: d3.select(window).on('load', function () { let mouseenterTime = 0; $(document).on('mouseenter mouseleave', '#gender_question', function (evt) { let currentTime = new Date(); if (evt.type === 'mouseenter') { mouseenterTime = currentTime.getTime(); } else if (evt.type === 'mouseleave') { mouseoverTime = currentTime.getTime() - mouseenterTime; $.ajax({ … -
