Django Rest Framework and AWS Cognito
Currently, I am using django-warrant to utilize cognito (JWT) based authentication to access APIs. After creating pool and app, I have set up following in my settings file: AUTHENTICATION_BACKENDS = [ 'django.contrib.auth.backends.ModelBackend', 'django_warrant.backend.CognitoBackend', ] COGNITO_USER_POOL_ID = 'poolid' COGNITO_APP_ID = 'app id' COGNITO_ATTR_MAPPING = { 'email': 'email', 'given_name': 'name', 'family_name': 'last name', } COGNITO_CREATE_UNKNOWN_USERS = False AWS_ACCESS_KEY_ID = 'access_key' AWS_SECRET_ACCESS_KEY = 'access_key_secret' In Midddleware, I have added: MIDDLEWARE = [ ............., 'warrant.django.middleware.APIKeyMiddleware', .............., ] In Installed apps, I have added, INSTALLED_APPS = [ ............, 'django_warrant', ............, ] In urls.py, I have added: path('accounts/', include('django_warrant.urls')) When I try to hit accounts/login url, it is throwing the error of missing templates. As I am using it for the first time, I am clueless how to proceed further with it to map django users with cognito users. I have searched tutorials related to this but found None. Please provide me guidance so that I can manage to proceed further. -
Django ORM When check
I would like to make a query to know whether particular user has relation with specific object. As for example: user = User.objects.first() modelA.objects.annotate(is_following_by_user=Case(When( XXXXXX, then=Value(True)), default=Value(False), output_field=BooleanField()))) XXXX should be replaced with code with checks whether followers_set.values_list('id', flat=True) contains id of given user. -
How to perform queries in django modelform?
I tried this in my modelform: class Ledgerform(forms.ModelForm): class Meta: model = ledger1 fields = ('name', 'group1_Name') def __init__(self, User, Company, *args, **kwargs): self.User = kwargs.pop('User', None) self.Company = kwargs.pop('Company', None) super(Ledgerform, self).__init__(*args, **kwargs) self.fields['name'].widget.attrs = {'class': 'form-control',} self.fields['group1_Name'].queryset = group1.objects.filter(User= self.User,Company = self.Company) In my views.py I have done something like this: class ledger1ListView(LoginRequiredMixin,ListView): model = ledger1 paginate_by = 15 def get_queryset(self): return ledger1.objects.filter(User=self.request.user, Company=self.kwargs['pk']) class ledger1CreateView(LoginRequiredMixin,CreateView): form_class = Ledgerform def form_valid(self, form): form.instance.User = self.request.user c = company.objects.get(pk=self.kwargs['pk']) form.instance.Company = c return super(ledger1CreateView, self).form_valid(form) I want to perform the the same query that I have passed in my ledger1ListView by using queryset in my modelform but my kwargs.pop is not returning the current user or the company... This is my models.py: class ledger1(models.Model): User = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,null=True,blank=True) Company = models.ForeignKey(company,on_delete=models.CASCADE,null=True,blank=True,related_name='Companys') name = models.CharField(max_length=32) group1_Name = models.ForeignKey(group1,on_delete=models.CASCADE,blank=True,null=True) Do any one know what I am doing wrong in my code? Thank you in advance -
How to handle different versions of design?
We have customers which can create their own profile page. The profile page has a cover image with a specific size. Some customers have already uploaded cover images in the specific size. In the next version of our we application (build in Django) we have made some design improvements which includes the change of the cover image size. What's the best way to handle this situation so old customers have the old design so the cover image still fits, but new customers get the new design? -
unsupported type for timedelta minutes component: F
My model: class ReigstrationToken(models.Model): token = models.CharField(_('Registration Token'), blank=False, null=False, max_length = 16, db_column='token', unique = True) valid_from = models.DateTimeField(_('Valid From'), default=timezone.localtime(timezone.now()), db_column='valid_from', blank=False, null=False) validity_period = models.IntegerField(_('Validity Period'), blank=False, null=False, default=30, db_column='validity_period', help_text = _('(Validity Period in Minutes from Valid From)')) Now I want to filter tokens which are not expire. So my query is like this: ReigstrationToken.objects.filter(valid_from__lt=datetime.now() - timedelta(minutes=F('validity_period'))) And it raises TypeError: unsupported type for timedelta minutes component: F I tried all possible solutions but that didn't work for me. ReigstrationToken.objects.filter(valid_from__lt=datetime.now() - timedelta(minutes=1)*F('validity_period')) It also raises TypeError: Connector must be + or -, not * Does anyone know whats wrong with this query? -

One User model for Auth and User Django
Im using the Django auth feature to create users. I also want to extend the user to add things like profile pictures and other information. My problem is that I now have to User models to manage. One from Auth and one from the model I created. Anyway to consolidate into 1 model please? from urls.py: path('accounts/',include('django.contrib.auth.urls')) from models.py: class User(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) firstName = models.CharField(max_length=200) lastName = models.CharField(max_length=200) image= models.ImageField(upload_to='profile_image',default='profile_image/SSMILE.jpg') from views.py class SignUp(generic.CreateView): form_class = UserCreationForm success_url = reverse_lazy('login') template_name = 'signup.html' As you can see I have 2 User models. I have to end up creating the auth user through sign up then in my homepage view do this: if str(request.user) != "AnonymousUser": try: getuser = User.objects.get(user=request.user) print(getuser) except User.DoesNotExist: newUser= User(user=request.user,firstName=request.user,lastName="change") newUser.save() which is a hack I want to avoid doing.

Django CSRF verification failed for a form created with AJAX
in my django project i create a huge part of my html page using javascript DOM (with AJAX calls). In one template in particular i create a form inside a lot of other things like this one: var jfrm = document.createElement("FORM"); jfrm.method = "post"; .... jfrm.addEventListener ("submit", function() { postJraEvent(data[index].id,data[index].t_pid,document.getElementById('txt2').value,document.getElementById('txt3').value,document.getElementById('txt5').value); }); whell, the function "postJraEvent" is another js func that using ajax execute some kind of tasks function postJraEvent(id_ev, th_id, j_issue, j_comm, j_file) { $.ajax({ type: "POST", url: "jirapost", data: {evid: id_ev, tid: th_id, jissue: j_issue, jcom: j_comm, jfile: j_file}, success: function (data) { $.each(data, function (index) { j_error = document.getElementById("laberr"); j_error.innerHTML = data[index].j_err; }); } }); } All done, but when i execute my code this error return: Forbidden (403) CSRF verification failed. Request aborted. The problem is i cannot insert the {% csrf_token %} inside the part of my template because i don't have it. (it was created dinamically by javascript) How can i resolve the CSRF verification failed in a case like this? Thanks in advance -
How do I use Loggly and Django to log a unique ID per session?
I have my Django logging setup like this (below). The filter for request ID comes from here, https://github.com/dabapps/django-log-request-id. I set up Loggly following the tutorial here: https://www.loggly.com/docs/python-http/. However, it appears their provided config file overrides the standard formatter, meaning it does not include request_id. Is there a way I can use both request_id and Loggly? Basically, I would like Loggly to always log a request_id which is unique and comes from the plugin log_request_id.filters.RequestIDFilter. LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'filters': { 'request_id': { '()': 'log_request_id.filters.RequestIDFilter' } }, 'formatters': { 'verbose': { 'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s' }, 'simple': { 'format': '%(levelname)s %(message)s' }, 'json': { 'format': '{ "loggerName":"%(name)s", "timestamp":"%(asctime)s", "fileName":"%(filename)s", "logRecordCreationTime":"%(created)f", "functionName":"%(funcName)s", "levelNo":"%(levelno)s", "lineNo":"%(lineno)d", "time":"%(msecs)d", "levelName":"%(levelname)s", "message":"%(message)s"}', }, 'standard': { 'format': '%(levelname)-8s [%(asctime)s] [%(request_id)s] %(name)s: %(message)s' }, }, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'filters': ['request_id'], 'formatter': 'standard', 'stream': sys.stdout, }, 'loggly': { 'level': 'DEBUG', 'class': 'loggly.handlers.HTTPSHandler', 'filters': ['request_id'], 'formatter': 'standard', 'url': 'https://logs-01.loggly.com/inputs/TOKEN/tag/python', }, }, 'loggers': { 'django': { 'handlers': ['console', ], 'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'), }, 'root': { 'handlers': ['loggly', ], 'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'), } } } -

Git Clone - Python Forum
I cloned https://github.com/nitely/Spirit - awsome forum by the way. Because I want to use it as a boilerplate to make my own forum... First thing is I want to find out how to replace everything that say's Spirit , with whatever I decide on my blog name. How Can I find in the cloned file's where to replace them - I have already ran the webpage locally and 'inspected' the element.. just cant trace back to the exact html/css/python/js file. Also , I am a newb, this is a common or "ok" thing to do correct - clone someones code and use it as a boiler for another project? I will give credit. -
Django : Error when starting supervisorctl : ImportError at / No module named ___

Django Migrate from Char Field to Integer Field?
I changed one of my CharField in models.py:: models.CharField(max_length=128, blank=True) into IntegerField --> models.IntegerField(default=0) I have data for that field, mainly empty strings("") or integer as strings(eg: "10"). So I would like to convert these strings to integer while migrate. eg:: if blank string("") convert to 0, else convert to integer. How can i achive that while i do ./manage.py migrate command? here is the migration file created using ./manage.py makemigrations:: # Generated by Django 2.1.2 on 2018-10-25 04:57 from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ('dashboard', '0002_auto_20181024_1544'), ] operations = [ migrations.AlterField( model_name='aclpermissions', name='ordering', field=models.IntegerField(default=0), ), migrations.AlterField( model_name='submenus', name='ordering', field=models.IntegerField(default=0), ), migrations.AlterField( model_name='subsubmenus', name='ordering', field=models.IntegerField(default=0), ), ] When i run ./manage.py migrate i got error :: psycopg2.DataError: invalid input syntax for integer: "" because there are fields with empty strings "". -

I need to utilize the BooleanField on the front end
I want the user to use the BooleanField to pick which meals said animal eats (breakfast, lunch, dinner, a combination of these possibly). And if the checkbox is checked I then want it to produce a schedule on screen where you can check off if the animal has eaten said meal that day. The issue is whenever I add my schedule, it will not produce a schedule where I can check off if the animal has eaten. (I know this explanation may sound confusing).

Django Rest Framework Send Data to View Without Serializer
I have a Magic model in my application. I need the user who is attached to this model to go to their email address to verify something before they can access the information. This should happen over a RESTful API. The problem is, the user should not necessarily be logged in to access this feature (for design decisions I had no control over). I have implemented the logic for generating the necessary information and sending the email (only if such an email is registered), authentication once the emailed information is accessed, etc. My question: How do I implement a view that takes a user email in the body (or url)? Approach 1: create a url /magic_api/v1/tdbverification/(?P<email>[\w.@]+)/ and extract the email address and send the email. Problem with 1: I cannot seem to extract the email and I need to return a json object without having a serializer Approach 2: Create a view that takes body: {"email": "<email@here.com>"} Problem with 2: This requires a serializer without a model (as this view is just for sending the email, it does not change model objects). I tried working with a serializers.Serializer class but could not figure out how to incorporate the email sending … -
