How to implement 'others' in django models choices-charfield
was wondering if anyone here know of a good implementation for 'others' choice (where user can input custom text) in django models multi-select .... say for instance i have a multiple choice model field 'options' with pre-set a and b choices. options = models.CharField ( max_length=2, choices=[(a,'a'), (b,'b')], default=a, ) What if I want the user to be able to select a choice 'others' and thereon key in his custom text i.e. 'd' The only way I can think of really, is to use a different field , say options_custom (without getting into the specifics of the model etc...the dummy snippet below is just for discussion sake) options = models.CharField ( max_length=2, choices=[(a,'a'), (b,'b'), ('others', 'others')], default=a, ) # added this.. options_custom = models.CharField(max_length=2, blank=True, verbose_name="Input custom text here" ) # and put a conditional... if others then return options_custom if choices == 'others': return options_custom # something like this.... What do you think? I'd appreciate any pointers. -
Django charfield regex
Consider a charfield with a max_length of 5. I want to put hours and minutes in this CharField like HH:MM. I don't want to use the models.TimeField as it stores the time, not the amount hours and minutes. I want my CharField to hold, let's say, 8:45 (8hrs and 45minutes) which is why I want to add a regex validator that makes sure that the number before the colon : is less than 24 and the number after it less than 60. How would I do that in regex? Thank you for your time. -

How to create proxy-http-server
I write a proxy-http-server on the Django using django-revproxy. re_path(r'^(?P<path>.*)$', ProxyView.as_view(upstream='https://example.com')) It works.

How to show what changed in a model using Django simple-history?
I am using django-simple-history to track changes in a model. This is working fine. I can also create a view for the admin site. When I do not derive the class for the admin view from SimpleHistoryAdmin I get this history view showing what changed in the model under the column ACTION (last column). However, I cannot revert the values for the object to a previous time point. If I derive the admin view class from SimpleHistoryAdmin I can revert the instance but the history view changes and I no longer have the ACTION column. This makes this view almost useless since there is no way to tell what changes from one-time point to the other. So my question is: How can I have the column ACTION in the history view when I derive the admin view from SimpleHistoryAdmin? If by any chance this is not possible I will be happy by changing CHANGE REASON from None to the values in the column ACTION in the first image. -

Django problem accessing Admin while my main DB is Mongo
my name is Víctor. I'm quite new using Django and Python and I'm working in a project that is yet started. Default Database is MongoDB where I have users and I can authenticate in the login page of the app. Now we installed 'helpdesk' app that is a ticketing system and we would like to use Admin that is disabled in our project. I added Admin app in Settings and Url but I dont have any access to any user. I tried to create a superuser with python manage.py createsuperuser but it gives me this error: TypeError at /admin/ int() argument must be a string, a bytes-like object or a number, not 'ObjectId' In django/contrib/auth we made some changes for example: def _get_user_session_key(request): # This value in the session is always serialized to a string, so we need # to convert it back to Python whenever we access it. if SESSION_KEY in request.session: return ObjectId(request.session[SESSION_KEY]) Where appears this ObjectId, it seems that Admin is trying to access user from MongoDB and not from helpdesk DB that is sqlite. Probably my problem is that I dont understand about mixing databases and accessing. I created a router with functions like: class RouterDB: … -

OTP only login for Django
I would like to have OTP only for authentication. I read about django-otp and django-two-factor-auth but they are both for two-factor authentication. I read the examples in the github and unfortunately do not know if it is possible to make if OTP authenticated only based on limited experience. I was thinking about using native python and Javascript for this, but I guess decorators @login-required requires Django Login? I would also like to log the user activity with Matomodjango-analytics in the future. I am not sure if I have to use Django Login in order to track activities later. Thanks for your suggestion! -

Change src attribute in <img> tag created by ckeditor in django
I am using django-ckeditor which includes image upload. Code created by editor is following: <p><img alt="" class="img-fluid" height="687" src="/media/uploads/2019/11/04/yoga_m.jpg" width="1030" /></p> I have added class="img-fluid" by this JS code: CKEDITOR.on('instanceReady', function (ev) { ev.editor.dataProcessor.htmlFilter.addRules( { elements : { img: function( el ) { // Add bootstrap "img-responsive" class to each inserted image el.addClass('img-fluid'); } } }); }); problem is I have to send content in API and I need absolute path in src (src="http://127.0.0.1:8000/media/uploads/2019/11/04/yoga_m.jpg" not src="/media/uploads/2019/11/04/yoga_m.jpg") Can anyone help please? -

Django refrence non field value at database level
class Author(models.Model): ... class Book(models.Model): author = models.ForeignKey(Author) book_seq = models.PositiveIntegerField() class Meta: unique_together = ('author', 'book_seq') def create_book_for_author(cls, author): book_seq = Book.objects.filter(author=author).count() + 1 Book.objects.create(author=author, book_seq=book_seq) Is there any way to reference this book_seq = Book.objects.filter(author=author).count() + 1 at database level because if this line concurrently then the unique constraint will fail and the second one to reach the database with insert query will fail. I know one option is transaction but is there any other way? F() object only works with concrete field not with database query.
