Create object only if other object is successfully created
I am fairly new to Django and unfamiliar with the best practices for this situation (in any framework/language, not just python/django). The situation is that when a user first registers on my site, I want to create an "organization" for them if it doesn't exists, and then subsequently create a user for them, which references the organization. I never want to insert one without the other, but I need to create the organization first so that the organization UUID can be saved for each user. Right now, organizations will still be created even if there is an issue with the creation of the user. This is obviously a problem because then I have an organization with no users attached. I don't exactly know how to check that the user will be properly created before creating the organization, but something along these lines seems to be what I need to do. Using commit=false on the organization object creation wouldn't seem to work because I need to get the UUID. So I am not sure the best way to proceed. I am overwriting the save method in the serializer of the popular authentication package django-allauth models.py class Organization(models.Model): alphanumeric_plus_underscore = RegexValidator(r'^[\w]+$', 'Only … -

Is there any method or procedure to prevent jQuery to apply all the same classes except current class?
I have situation to apply some jQuery to current class which should not apply to remaining classes of having same name.

Should i be using my views.py do load data instead of Jquery/Ajax?
I am working on a Django based webapp where i pull some JSON data from an external api into a html bootstrap modal. From there I do some calculations on the data and select certain entries, change their html class etc. Currently i am using an Ajax get request to retrieve the data and then straight javascript to show it in the modal and do the class changes and calculations. I am thinking that it might be better to do this from my Django views.py file instead What i have done so far Ajax Get Call $.ajax({ cache: false, method: 'GET', url: url, success: function(data){ console.log(data) console.log("success") showTable(data) $('#total').text(doSum(".price>span")) }, error: function(error_data){ console.log("error") } }) Showing the Data in a table in the modal function showTable(data) { $("#food_table tbody").html('<tr class="contentRow">' +data.map(v=>'<td>'+v.pk+'</td><td>' +v.Description+'</td><td class="price">R<span>' +v.Price+'</span></td></tr>' ).join('')); } My Bootstrap Modal and Table <div id="firstModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="firstModalLabel" aria-hidden="true"> <div class="modal-dialog modal-lg" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="firstModalLabel">Table 1</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> <div class="container"> <div class="table-responsive"> <table class="table table table-borderless" id="food_table"> <thead> <tr> <th>#</th> <th>Description</th> <th>Price</th> </tr> </thead> <tbody></tbody> </table> </div> </div> </div> <div class="modal-footer"> <div class="container"> <div><h3 class="h3total">You Owe: … -

How can I fill up a form field from views.py in Django?
I am using a function to record the time between which the page is loaded and the user submits the data. In that form, I have created a hidden field so that the admin can see it. However, I am unable to implement my idea since I don't understand how I can submit the time to the form from views.py. If someone can suggest an easier and simpler alternative methods to achieve what I am trying to do, that would be very helpful to me as well. My code is as follows. models.py class Responses(models.Model): question1 = models.TextField() question2 = models.TextField() question3 = models.TextField() timespent1 = models.TextField() forms.py class Question1Form(forms.ModelForm): question1 = forms.CharField() timespent1 = forms.TimeField(widget=forms.HiddenInput()) class Meta: model = Responses fields = ('question1','timespent1') views.py def qone(request): if request.method =="GET": starttime = my_timer() elif request.method == "POST": form = Question1Form(request.POST) if form.is_valid(): endtime = my_timer() timespentstr = '{0} seconds'.format(endtime-starttime) #Do something to set timespent1 field = timespentstr here form = form.save() else: form = Question1Form return render(request,'question1.html',{'form':form}) -

replacing django_background_task with APScheduler in Django?

Django - Adding a part of a string onto a new line not working correctly
In my Django project, If the user makes a mistake when signing up, then an error is sent to my template and then displayed. Some of my error messages I send to the user are a bit lengthy, and therefore I want to start a new line within the text. I attempt to add \n within my text, however a new line isn't started. Here's my code: views.py: return render(request, 'users/signup.html', {'error': 'Username field must be \n a minimum of 5 characters'}) signup.html: {% if error %} <span class="errorspansignup"> {{ error }} </span> {% endif %} The text I pass as error stays all on one line. Does anybody know what the issue is? Thank you. -
Error occured in django when i run a command `python manage.py runserver`.after i changed python version
everyone here in stackoverflow. I had successfully completed few django projects few month ago. Now, due to some reason i changed the python version.

Password Reset issue with Django 2.2.5
I am trying to figure out an issue I'm having with what happens after submitting the password reset form supplied by django.contrib.auth.urls. When hitting the button to request the submit button an email is sent properly to the email associated with the user account, but a 505 error page is displayed. In looking at the error log the error given is: Reverse for 'password_reset_done' not found. 'password_reset_done' is not a valid view function or pattern name. In myproject/urls.py I have the following line as part of the urlspattern: path('accounts/', include('accounts.urls', namespace = 'accounts')) In accounts/urls.py I have the following lines as part of the urlspattern: path('', include('django.contrib.auth.urls')) I think the issue is with django attempting to use the equivalent of url 'password_reset_done' instead of url 'accounts:password_reset_done'. Any help in tracking this down would be appreciated. -

Pulling several Django models together into a single list
I have a database with four related tables: project, unit, unit_equipment, and equipment. A project can have many units; a unit can have many related equipment entries. A single unit can only belong to one project, but there is a many-to-many between equipment and unit (hence the unit_equipment bridge table in the DB). I'm using Django and trying to create a view (or a list?) that shows all 3 models on the same page, together. So it would list all projects, all units, and all equipment. Ideally, the display would be like this: Project --------- Unit ------------- Equipment Project 1 first_unit some_equipment1, some_equipment2 Project 1 second_unit more_equipment1, more_equipment2 Project 2 another_unit some_equipment1, more_equipment1 Project 2 and_another_unit some_equipment2, more_equipment2 but at this point I'd also be happy with just having a separate line for each piece of equipment, if comma-separating them is a pain. I am very new to Django, and although it seems straightforward to create a form where I can add a new project, and add related unit and equipment data (using the TabularInline class), I cannot for the life of me figure out how to bring this data together and just display it. I just want a "master … -
Checking a value of single cell on uploaded excel file on Django via openpyxl
I am currently taking an excel file as an input from Django. From the uploaded excel, I would like to check a value in one cell and decide on what to do with the entire workbook. But my syntax for load_workbook must be wrong as I am getting 'stat: path should be string, bytes, os.PathLike or integer, not UploadFileForm' What would be the simplest way to interpret the uploaded file as an excel file and check a value of the single cell? From the upload function, if self.request.method == 'POST': form = UploadFileForm(self.request.POST, self.request.FILES) if form.is_valid(): # edit workbook = load_workbook(filename=form, read_only=True) uploadable(workbook) I cannot change the part above the edit tag as it is being used by many different working functions. The snippet of the uploadable function: def uploadable(wb = None): firstws = wb[0] if firstws['X1'] == 1: return render_to_response('check/wrongfile.html') -

Is it possible to fill a form in a test?
I want to test a form. It is working, but the test doesn't. One field of this form is popolated by a javascript function. I can use selenium to do so, but I don't want because it's giving problems and also I want isolate the test. So I'm calling the form in my test, then I'm creating the choices (this is what javascript should do), then I'm setting the fields values.
