how to set username to python request explicitly
Trying to set token and username to python request.get session, so that next consecutive session.post must have both the session and username. I am able to set the token, however I tried setting the username, but next post call doesn't carry it. request.session['account_token'] = encoded_token - this works request.user = username - doesn't work Expected result should be - with the get call, I should be able to set the username and encoded token to the session and using these set values next post call should be able to authenticate the request and proceed as intended. -
Save data from radio button to database Django
I need to know how to save data to database if I use radio button and it name is inconstant becuase I use template tag for name value.

Django How can I unittest a wait function for db written in bash script when using dockerized database service?
After searching stackoverflow for a while, I found plenty of ways to check if dockerized database service is ready before connection. So I include both of them here. first one is written in bash script and I found it in here if [ "$DATABASE" = "postgres" ] then echo "Waiting for postgres..." while ! nc -z $SQL_HOST $SQL_PORT; do sleep 0.1 done echo "PostgreSQL started" fi python manage.py flush --no-input python manage.py migrate exec "$@" The second one is written in python and I found it in here: class Command(BaseCommand): """Django command that waits for database to be available""" def handle(self, *args, **options): """Handle the command""" self.stdout.write('Waiting for database...') db_conn = None while not db_conn: try: connection.ensure_connection() db_conn = True except OperationalError: self.stdout.write('Database unavailable, waiting 1 second...') time.sleep(1) self.stdout.write(self.style.SUCCESS('Database available!')) I use this docker command ENTRYPOINT ["/usr/src/app/entrypoint.sh"] to run the first one. I know how to write unit tests for the second one, because it's in python. But can anyone help me find a way to write tests for the first one? In addition, Can anybody name what are the drawbacks and advantages of each method and also if there exists some other important considerations for writing such function? Thanks -

Django DRY model attributes, classes, and triggers
I'm hacking on an graph-based app with about 50 different types of relationships. They all look like this. class SomeModel(CustomClazz): created_at = DateTimeProperty(default_now=True) updated_at = DateTimeProperty(default_now=True) class Meta: app_label = 'custom_relation' def save(self, *args, **kwargs): self.updated_at = datetime.now() super(SomeModel, self).save(*args, **kwargs) When I started writing this post, I was just looking for a one-liner for class Meta: but I realized most of these lines are duplicates for each model. Although I view the integrity and human-readability of the model as sacred, part of that is keeping my model file short enough that I don't need to split it up into many files. If the model definition becomes extremely dry, I'd still like to be able to set custom attributes for SomeModel. -
How to get the plain password from the password field in the signup form in Django
I have the sign up form in django through which I am taking the entry for the new user. The data can be saved using the u_form.save method but I also need the plain password that the user has entered as that password will be needed to create account in other website through the REST API and hence both password needs to be same. I am able to access the password from the form but when I receive it Django has already encrypted it. How can I get the original plain password? This is what I have tried : views.py from users.forms import SignUpForm, ProfileForm def create(request): context = {} if(request.method == 'POST'): u_form = SignUpForm(request.POST) # fill it with user details p_form = ProfileForm(request.POST, request.FILES) if u_form.is_valid() and p_form.is_valid(): user = u_form.save() email = user.email username = user.username first_name = user.first_name # Accessing plain password password = user.password Profile.objects.filter(user=user).delete() profile = p_form.save(commit=False) profile.user = user profile.save() messages.success(request, f'Account Created') return render(request, 'mainapp/homepage.html', context) forms.py from django.contrib.auth.forms import UserCreationForm from django import forms from django.contrib.auth.models import User from .models import Profile class SignUpForm(UserCreationForm): email = forms.EmailField(required=True, label='Email', error_messages={'exists': 'Oops'}, widget=forms.TextInput(attrs={'readonly':'readonly'})) username = forms.Field(widget=forms.TextInput(attrs={'readonly':'readonly'})) first_name = forms.Field(widget=forms.TextInput(attrs={'readonly':'readonly'})) readonly_fields = ('username', 'first_name', … -
Testing a form. What'happening? is this really working?
I have a django form with a field directed to a foreignkey. Initially is empty, I mean without any option. Javascript will add options based on another form field. It's working but I want to test it, without using Selenium (and so, without using javascript). After numerous attempts I write this code and apparently it's working but I don't know why and I'm not sure it's really working. def test_form_validation(self): maschio = Gender.objects.create(name_en='Male', name_it='Maschio') nome = NameType.objects.create(name_en='Name', name_it='Nome') romani = NameLanguage.objects.create( name_en='Romans', name_it='Romani') romani.syntax.add(nome) form = NameForm({'nametype': nome.id, 'gender': maschio.id, 'name': 'Remo', 'namelanguage': romani.id}) # print('1', form) form.fields['nametype'].initial = nome.id form.fields['gender'].initial = maschio.id form.fields['name'].initial = 'Remo' form.fields['namelanguage'].initial = romani.id print('2', form) form.save() self.assertEqual(Name.objects.all().count(), 1) my_name = Name.objects.first() self.assertEqual(my_name.name, 'remo') self.assertEqual(my_name.nametype, nome) self.assertEqual(my_name.gender, maschio) self.assertEqual(my_name.namelanguage, romani) print('end of test') # print('1', form) is commented out because with that the test will be give error on line form.save() (ValueError ... the data didn't validate). Without that line the test pass (!?!). I will expected an error when I call my form bounded because nametype has no option to choose from. nome.id is not one of the ammissible choices. And in effect, as I said, it will give an error if I ask … -
Django Custom Setting Size Attribute on Model Form Not Working
I am trying to specify the length in characters on a model field. I cannot get it to render on the page and drop in the size attribute to the input field. The basic form looks like: class QuestionForm(ModelForm): question = forms.CharField(label="Question") class Meta: model = Question fields = ["question"] I have tried the following: class QuestionForm(ModelForm): question = forms.CharField(label="Question",widgets=forms.TextInput(attrs={'size':'50'})) class Meta: model = Question fields = ["question"] And class QuestionForm(ModelForm): question = forms.CharField(label="Question") class Meta: model = Question fields = ["question"] widgets = { 'question': forms.TextInput(attrs={'size':'50'}) } And class QuestionForm(ModelForm): question = forms.CharField(label="Question") def __init__(self, *args, **kwargs): super(QuestionForm,self).__init__(*args, **kwargs) self.fields['question'].widget.attrs['size'] = '50' The form is part of a formset factory, do you need to do anything different when using that? ApplicationForm = forms.formset_factory(QuestionForm) ModelApplicationForm = forms.modelformset_factory(Question, fields=('question',)) -
django , angular :- How to render the page according to the session status?
We are checking the session details from Django-sessions. If the session is active the "Layout.html" page should open else "login.html" page should open. Both "Layout.html" and "login.html" are in Angular 7. I have tried to send the JSONdata(status of login) using render() from django to angular and according to that status I used "*ngIf" to open the files, but I was not able to access the JSONdata outside the index.html
