Django: authenticate user using another application
I have two django applications, A and B, which make use of the same User model. The User model is in A , and B sends a request to A for user authentication as follows: # Application B: url = ... # Application A's url data = {'username':request.POST.get('username'), 'password':request.POST.get('password')} resp = requests.post(url, data=data) # A authenticates with the username and password if resp.text == 'True': # login the user: how? user = ... else: # Login fails My question: how do I create an authenticated user in B? -
How can I pull out a row in a GROUP BY Django query?
I have a table like this: EVENT ------------- user_id thumbnail_name 0 event/abc.jpg 0 event/efg.jpg 0 event/xyz.jpg 1 event/lmn.jpg 1 event/opq.jpg 2 event/rsf.jpg How can I GROUP BY user_id and retrieve an arbitrary thumbnail? Expected output: [ {user_id: 0, thumbnail_name: event/abc.jpg}, {user_id: 1, thumbnail_name: event/lmn.jpg}, {user_id: 2, thumbnail_name: event/rsf.jpg}, ] Is this even possible in SQL? -
Django save() method filling a certain field with None when saving with same id
I have this model. class Country(models.Model): countryname = models.TextField(null=True) countryincharge = models.ForeignKey(Employees, on_delete=models.CASCADE,null = True) createdby = models.TextField(null=True) createdtime = models.TextField(null=True) modifiedby = models.TextField(null=True) modifiedtime = models.TextField(null=True) deletedby = models.TextField(null=True) deletedtime = models.TextField(null=True) isdeleted = models.IntegerField(null=True) tenantid = models.TextField(null=True) And create and update functions as following. #Create def countrycreate(request): if request.user.is_authenticated: if request.method == 'POST': id = request.POST.get('id') modelwithdata = Country( countryname=request.POST.get('countryname'), countryincharge_id=request.POST.get('countryincharge'), createdtime = timezone.now(), createdby = request.user.id ) if Country.objects.filter(countryname=request.POST.get('countryname')).exists(): messages.info(request, 'Country already exists!') return HttpResponseRedirect(request.META.get('HTTP_REFERER')) else: modelwithdata.save() return redirect('/admin/countrylistview') #Update def countryupdate(request): if request.user.is_authenticated: if request.method == 'POST': id = request.POST.get('id') modelwithdata = Country( countryname=request.POST.get('countryname'), countryincharge_id=request.POST.get('countryincharge'), modifiedtime = timezone.now(), modifiedby = request.user.id ) modelwithdata.id = id modelwithdata.save() return redirect('/admin/countrylistview') The problem is when a record is created the createdtime value is saved as intended. But when running the update function the createdtime value is set to None. For unknown reasons. Other fields are working fine. The db is SQLite. Same behaviour happens when use DateTimeField(auto_now_add=True, null=True) and DateTimeField(auto_now=True, null=True). -

How to create a comment box with user mention feature in django?
I am trying to create a comment box for my django app with user mention feature. When a user trying to comment with "@" then the list of users should be listed and selected for mentioning.

Also you can suggest any available app library for comments with this feature. Thank you in advance. -

Does Django close and delete TemporaryUploadedFiles and InMemoryUploadedFiles?
I have read through all the documentation for TemporaryUploadedFiles and InMemoryUploadedFiles but they talk about clean up.

Easiest way to import and export csv files to models without django-admin
I am new to django and learning a lot through this forum while building a small app however I am stuck at point in the development and will be able to complete my app with this segment. I have read online lot of documentation around how to import and export csv files into django models however all the codes/docs I read need the code to be written to map the columns manually from the csv to models. However I want to build a form where I want the user to select the table name from the dropdown and upload the csv file accordingly. Can this be achieved easily by dynamically comparing the model fields to csv headers and import if all of them match? This would be a huge help if you can put me int he right direction towards how this can be achieved. I am currently using oracle as my app database. Thank you so much. -

Convert Boolean To Custom String
I have boolean values in my database and within a Django project I am printing them to a pdf. Its very minor but id like them to print as yes/no rather than true/false. I know that I could use yesno if I was outputting booleans in a template: https://docs.djangoproject.com/en/3.0/ref/templates/builtins/#yesno But I am outputting these within a function. I also know I could use an if/else statement, but was hoping for something a bit cleaner. IE - Is there a short, clean way to convert boolean values to custom strings. Thank you. -

Dynamically Update SelectMultiple Widget Option Attributes in Django Form
I'm utilizing Django Forms for my web application's front-end filter functionality, and I'm making a few Field & Widget customizations so that I may present multi-select checkboxes as follows: [x] Doug Funny (1) [ ] Skeeter Valentine(5) [x] Patti Mayonnaise(3) [ ] Roger Klotz (9) Upon selecting an option, I'm able to dynamically update the checkbox field labels (the counts, specifically) by overriding my Forms init method as follows: class FiltersForm(forms.Form): ... dateRadio = forms.ChoiceField(required=True, choices=CHOICES, widget=forms.RadioSelect) studentCheckbox = MyModelMultipleChoiceField(widget=MyMultiSelectWidget, queryset=Student.objects.all(), required=False) gradeCheckbox = forms.MultipleChoiceField(required=False) ... def __init__(self, *args, **kwargs): super(FiltersForm, self).__init__(*args, **kwargs) students = Student.objects.values(...).annotate(count=Count(...)) self.fields['studentCheckbox'].queryset = Student.objects.all() # dynamically updating the field's label here to include a count self.fields['studentCheckbox'].label_from_instance = lambda obj: "%s (%s)" % (students.get(pk=obj.pk)['name'], students.get(pk=obj.pk)['count']) But rather than "hardcode" the counts in the field label, I'd like to dynamically set the count as a 'data-count' attribute on each of the widget's option fields. In my attempt to do so, I've subclassed forms.ModelMultipleChoiceField as MyModelMultipleChoiceField. It's my hope to override the label_from_instance function in MyModelMultipleChoiceField to dynamically access the obj (by pk) and set a data-count attribute in the process. For some reason, however, the label_from_instance function isn't being called from the Form's lambda (self.fields['studentCheckbox'].label_from_instance). I've also … -
Pass model data from one view to another view using Django
I am new to Django and stuck on this problem. Basically page1 will ask the user for the name and address. I am doing this by using a model form. My model looks something like this class Person(models.Model): first = models.Charfield(max_length=100) last = models.CharField(max_length=100) street = models.CharField(max_length=100) state = models.CharField(max_length=100) country = models.CharField(max_length=100) phone = models.CharField(max_length=100) c_num = models.CharField(max_length=100) c_exp = models.CharField(max_length=100) And my form on my first page looks like this: class PersonForm(forms.ModelForm): class Meta: model = Person fields = ['first', 'last', 'street', 'state', 'country', 'phone'] So I basically get the users information on the first page using the form. Then that updates my model but leaves the c_num and c_exp blank. Then on the second page I want to display the information that the user just entered and also prompt for the c_xxx properties. However, I am not sure how to update the current Person object. How would I search through all objects to find the current one the user is creating? -
