default fields not working with an Embedded field on save(), in a django project with mongoDB
Let's say I have the below structure of Models for a django project with MongoDB Database, using djongo as DB engine. When I am trying to add a Department record if I don't provide the salary field which is marked as default=0 in the query am getting a ValidationError for not suplied fields class Person(models.Model): name = models.CharFields() surname = models.CharFields() salary = models.FloatField(default=0) class Meta: abstract = True class Department(models.Model): name = models.CharFields(max_length=60, unique=True, null=False) persons = models.EmbeddedField(model_container=Person) If I run the below query: Department( name='Networking', persons = { 'name': 'Mike', 'surname': 'Jordan' } ).save() I get a Validation error for not supplied field (Since is marked as default=0, why django asks for it ?): django.core.exceptions.ValidationError: ['{\'salary\': [\'Value for field "Project.Person.salary" not supplied\'] -

Django authenticate() don't work after first logout

Django - build form fields from database dynamically
I hope the title of this question is as it should be based on this explanation below. I have a model as below: class Setting(models.Model): TYPE_CHOICES = ( ('CONFIG', 'Config'), ('PREFS', 'Prefs'), ) attribute = models.CharField(max_length=100, unique=True) value = models.CharField(max_length=200) description = models.CharField(max_length=300) type = models.CharField(max_length=30, choices=TYPE_CHOICES) is_active = models.BooleanField(_('Active'), default=True) I use this to save settings. I have don't know all settings in advance and they can change in future. So I decided to save attributes and their values in this model instead of creating columns for each setting(attribute in the model). Now the problem I am facing is how do I present form with all attributes as fields so that a user can fill in appropriate values. Right now, as you can see, form shows columns 'Attribute' and "Value" as labels. I would like it to show value of column 'Attribute' as label and column 'Value' as field input. For example, in Setting model I have this: Attribute ------------ Value 'Accept Cash' ---------- 'No' I would like to appear this on form as <Label>: <Input> 'Accept Cash': 'No' I think I will have to build form fields from the database(Setting model). I am new to this and have … -
cookie isn't stored in browser localstorage cookies
hi I have a question about cookie first i'm using djangorestframework for backend and using react for frontend second, i decided to use jwt token for login authentication so i made jwt token and using django set_cookie() method for response cookie(jwt token is stored) enter image description here like this. and this is my cors settings in my settings.py file enter image description here and in the frontend side(react) enter image description here I wrote my code like this. so, what I expected was .. when I send 'login/' request, server check the id and password and if that is correct response with cookie(with jwt token) and that cookie is stored in local(browser) storage cookie part enter image description here but.. as a result.. enter image description here I got a cookie(with token) from response(that image is network tap) but.. it isn't stored in localstorage cookies as I uploaded above.. so, please tell me what is the solution with my case.. i tested it localhost react is 3000 port and django is 8000 port -
(Django 3.1.6/Python 3.8.7) Using a named method in fields or fieldsets admin.py does not work?
No matter what I try I cannot use a named method as a field name like they do in the docs. Eventually I'll make the method retrieve a field of a ForeignKey but for now I just want to figure out what I'm doing wrong with this simplified example. In this example from docs.djangoproject.com they are using the class method 'view_birth_date' just as I am using 'get_test' (below) and even through I'm using it in fieldsets instead of fields it should work. I've tried it with fields = and fieldsets = and I get the same result (error). It cannot find the field 'get_test' either way. I've also tried putting the def get_test(self) above the fieldsets = but it makes no difference. It should work the same as what is in the documentation but it does not. What am I doing wrong? This should work: @admin.register(Feeddata) class AdminFeeddata(admin.ModelAdmin): """Feeddata admin.""" list_display = ['id', 'eventtime', 'feed'] fieldsets = [ ('Meta', { 'fields': ['feed', 'eventtime', 'get_test'] }), ('JSON Data', { 'fields': ('json_data', ) }), ] # pylint: disable=no-self-use def get_test(self): """Test string.""" return 'test' But I get an error: FieldError at /admin/feeder/feeddata/fff1d764-52cd-499f-9ae9-b1251a806b5b/change/ Unknown field(s) (get_test) specified for Feeddata.

Bounding box with longitude less than -180 django postgis
I'm trying to add a bounding box to django model. c.bounding_box = Polygon.from_bbox((-194.06250000000003, 31.952162238024975, -21.796875000000004, 76.3518964311259)) c.save() It works fine, but when I access django admin, I see incorrect box. I think it is because of the longitude less than -180. How can I fix it? -
How critical is pylint's no-self-use?

Django can't load static files even though all settings are fine

Django + Pymongo creating account confirmation link
I am building a user module from scratch where users can do pretty much all regular user operations from login,signup,..., to account deactivation. The thing is that I am not using mongoengine or django ready-made models that simplify sql connections, instead I am doing everything from scratch using pymongo driver to connect to mongodb database where I need to code all CRUD operations. I am stuck at creating a temporary link for users to (1) confirm account - this link should not be expired, (2) reset password, this link expires in few days. I have two questions regarding this: 1- can i still use django token generator/ authentication library? I am not using Users django library so my users are just ones I create and insert to database, if yes how can i do that?! 2- if no, how can I generate those temp links considering similar level of security that django library adopts, i.e. hashed username/ salted.. etc. any advice if I am doing something wrong or I should re-do everything considering mongoengine as my driver so that I can inherit and use django models?! any recommendation is highly appreciated. Thank you -

Building web applications around TTN: how to best store the data (DynamoDB or PostgreSQL)?

Django User.date_joined.date using UTC time?
In my template, I want to show the join date of a user, so I am using {{ user.date_joined }} which shows the date and time (in local time zone - same as what is shown in the admin panel). To just show the date, I use {{ user.date_joined.date }}, but it seems to be converting the date and time to UTC before showing the date (I am in EST/EDT - I never remember which is which). For example: {{ user.date_joined }} ==> Feb. 18, 2021, 7 p.m. {{ user.date_joined.date }} ==> Feb. 19, 2021 Is there a way for me to change this so that it shows the same date as the full date and time? -
