Display Django model entries as part of a form
I want to display model entries as part of a form so I can update them. What is the best way to do this? I am using crispy forms. I first filter my object, and then I want to display this object as a form, where certain model attributes are display only, with some attributes being updated. Essentially a table containing all attributes for obj that cant be modified, with 2 attributes that will be updated in the form. forms.py: class ReportSampleForm(forms.Form): def __init__(self, *args, **kwargs): super(ReportSampleForm, self).__init__(*args, **kwargs) sample = self.data.get('sample_id', False) obj = VariantAnnotationSampleRun.objects.filter(sample_run_id=sample) self.helper = FormHelper() self.fields['id'] = forms.ChoiceField( required=True, label='blah:', widget=forms.CheckboxSelectMultiple, choices=((s.id, (s.variant_annotation_id.variant_id, s.attribute1, s.attribute2)) for s in obj) ) self.helper.form_method = 'POST' This displays check boxes with variant_id, attribute1 and attribute2, but I would like Model entries 'evidence' and 'annotation' to be filled in and if the checkbox is checked and form submitted, the database gets updated for that specific model entry. models.py: class VariantAnnotationSampleRun(models.Model): variant_annotation_id = models.ForeignKey(VariantAnnotation, attribute1 = models.DecimalField(max_digits=8, decimal_places=3) attribute2 = models.IntegerField() reported = models.BooleanField(default=False) evidence = models.TextField(null=True, blank=True) annotation = models.CharField(max_length=80, null=True, blank=True) Is this possible to do without building a totally bespoke form, from my view? -
Django listview to list only if it receives a true value
my name is Gustavo and I need help, I'm developing an application that generates requests (city hall) I'm using Django 1.11, in my shopping area I have a view using get_context_data to get the objects of my requests and list them. my problem is that there are several sectors and the request will only be listed in the next sector if the previous one approves. in my models.py I have the class Request (Solicitacao) and the class SecretaryApproval (SecretarioAprovacao) that is related to my request. What I need to do is when opening the page he checks all the requests and only lists for me the ones that receive the true value in the variable secretario_aprovacao view.py class Compraslist(LoginRequiredMixin, ListView): model = Solicitacao template_name = 'compraslist.html' def get_context_data(self, **kwargs): context = super(Compraslist, self).get_context_data(**kwargs) context['solicitacoes'] = Solicitacao.objects.all() return context models.py class SecretarioAprovacao(models.Model): secretario_relacionamento = models.ForeignKey(Solicitacao, on_delete=models.CASCADE) secretario_aprovacao_CHOICES = ( (True, 'Sim'), (False, 'Não') ) secretario_aprovacao = models.BooleanField("Aprovar Solicitação?", choices = secretario_aprovacao_CHOICES, default = True, ) class Meta: verbose_name = "Secretario Aprovação" verbose_name_plural = "Secretario Aprovações" thanks for listening. -
django model and csv file zip feature lack
I fixed a lot with your help and I guess we come to last problem; If the line from the csv file not in the my django model database than django mixes up all so that; csv line and django database are no longer going in correct order so all mixed. To prevent this problem I added if queryset count function within the loop to raise an error message or tried also pushing another default value but nothing worked. What you would suggest to prevent this sync problem ? for instance in RFP.objects.filter(FP_Item=query): if RFP.objects.filter(FP_Item=query).count() >= 1: instances.append(instance) else: messages.success(request, "ERROR") For reference the whole code: with open(path, encoding='utf-8') as f: data = csv.reader(f, delimiter='|') for row in data: line = row[0] lines.append(line) query = line for instance in FP.objects.filter(FP_Item=query): if FP.objects.filter(FP_Item=query).count() <= 1: instances.append(instance) else: messages.success(request, "ERROR") pair = zip(lines, instances) context = {'pair': pair, } return render(request, 'check_fp.html', context) -
Django Widget not Loading
I using Django with widgets to get some user input but I can't seem to get it to display even thou the code seems almost identical to examples online. forms.py from django import forms class PickerIDForm(forms.Form): pickeID = forms.NumberInput() views.py def get_id(request): template = loader.get_template('metrics/lance1.html') def get(self, request): form = PickerIDForm() return render(request, 'self.template', {'form': form}) context ={ } return HttpResponse(template.render(context,request)) urls.py from django.urls import path from . import views from . import mark_views app_name = 'metrics' urlpatterns = [ path('', views.index, name='index'), path('test/', views.get_id, name='get_id'), ] test.html {% extends 'base.html' %} {% block content %} <p>User Input</p> <form method = "post" > {% csrf_token %} {{form.as_p}} <button type="submit"> Submit </button> </form> {% endblock %} I'm never directly calling the get function as defined in views.py that to me seems to be a possible source of the input fields not showing up when I load up test.html At what point do you link the disparate parts together? Because it seems I'm missing something. -

django-models - a non-string type is stored into CharField
I am using Django 1.11 on Python 3, and MySQL 5.7. Suppose I have a model with a CharField, like so: class ModelA(models.Model): ID = models.AutoField(primary_key=True) a = models.CharField() And in the shell, I tried doing this: >>> instance = ModelA(a={'1' : 1}) >>> instance which gives me a TypeError: __str__ returned non-string (type dict) But when I do this: >>> instance.save() I don't get any error. If I try: >>> instance.a {'1': 1} But when I try: >>> ModelA.objects.get(ID=<the ID of the above instance>).a "{'1': 1}" Which means that it got stored in the database table as a string. My question is why does this implicit conversion happen, and why doesn't save() raise an error like __str__() did? Thanks for your help! -

How to Limit the number of suggestions from Summernote Mentions, w/ Django Rest Framework?
I am currently working on a project using Django, Django Rest Framework and Summernote. At the moment I am customizing Summernote WYSIWYG editor in order to offer my users the opportunity to mention other users. I am passing the user list to Summernote via Django Rest Framework. My Code at the moment looks like this: Grabbing the Users: //with this function I grab the user list from and endpoint that I set w/ Django Rest Framework function userList(){ console.log("fetching user list...") user_list = [] $.ajax({ url: '/api/users/user_list/', method: "GET", success: function(data){ for (i in data) { user_list(data[i].username); } } }) return user_list Django Rest Framework View Function: class UserListAPIView(generics.ListAPIView): serializer_class = UserDisplaySerializers queryset = User.objects.all() Summernote: hint: { mentions: userListt(), match: /\B@(\w*)$/, search: function (keyword, callback) { callback($.grep(this.mentions, function (item) { return item.indexOf(keyword) == 0; })); }, content: function (item) { return '@' + item; }, }, The Code Works. I Can get the user list and offer autocompletion features to my users.

Auto update cache with React Apollo and Django Graphene

in django drf can a authenticated user with token access other users data?
in django drf can a authenticated user with token access other users data? I know it shouldn't but in my application its not happening. for testing I was using the token in postman but I was surprised when I see by using one users token I can access any other user data by changing PK in url. when I researched this on internet I couldn't find any definite answer. may be I was using the token authentication method wrongfully... but my main question is: If I have one users token then by just changing pk in url, should I be able to get other users data? if so how to avoid that? (Note: I am currently NOT using HTTPS. ) (also this is a conceptual question so after getting answer of this I may need to ask another question regarding error in my code; that I will. but please provide answer to this) -

how to find if session has expired in django
I have to code this scenario: Some user comes to fill a form and while user is at it, session expires; User tries to submit form, as session has expired it will take him to login page after which he is rediredted to form page with a prefilled form with data he filled previously. my propsed solution: on form submit, check if user session is expired with an ajax call, if yes, drop a cookie with values of filled form, user comes back to same form, prefill the form from cookie value. how far I got: not much; I used ajax call to check session expiry with a backend call to this function: def check_valid_session(request): session_expiry_date = request.session.get_expiry_date() now = datetime.now() seconds_left = (session_expiry_date - now).total_seconds() if seconds_left <= 0: return JsonResponse({'session_expired': True, 'seconds_left': seconds_left }) else: return JsonResponse({'session_expired':False, 'seconds_left': seconds_left}) in my settings I have: SESSION_COOKIE_NAME = "sso-sessionid" SESSION_COOKIE_HTTPONLY = False SESSION_COOKIE_AGE = 10 SESSION_COOKIE_DOMAIN = '.mydomain.com' SESSION_COOKIE_SECURE = True SESSION_EXPIRE_AT_BROWSER_CLOSE = True but in response, I always get seconds_left as something close to 9.999. and session_expiry_time keeps increasing itself by 10 seconds each time i hit submit and call the backend code above.

django delimiter not working while reading csv file
I am working nowadays a lot with csv file and got another problem. If I do as per below, delimiter is not working. with open(path, encoding='utf-8') as f: data = csv.reader(f, delimiter='|') I searched and also tried below function: csv.register_dialect('options', delimiter='|') with open(path, encoding='utf-8') as f: data = csv.reader(f, dialect='options') It's not working as well. The main issue that I am having actually I am importing from a csv file a long text but only single colomn but if there is a comma in the text I loose the rest of the text after the comma.That's what I need to prevent. But it's not working. Should I use delimiter inside the for loop while writing ? -

Django form not calling custom validator
I'm using Django 2.0. This is my forms.py: class PostcodeForm(forms.Form): postcode = forms.CharField(required=True, widget=forms.TextInput( attrs={ 'placeholder': "enter a postcode", } )) def clean_postcode(self): postcode = self.clean_data.get('postcode', '') print('clean_postcode', postcode) if postcode != 'something': raise forms.ValidationError(_("Please enter a valid postcode"), code='invalid') return data And my views.py: def index(request): form = PostcodeForm() context = { 'form': form } return render(request, 'index.html', context) And my index.html: <form class="form-inline" id="lookup_postcode" action="{% url 'lookup_postcode' %}" method="get"> {% csrf_token %} {{ form.non_field_errors }} {{ form.postcode.errors }} {{ form.postcode }} <button type="submit">Submit</button> </form> But when I type in any value other than 'something', the form still submits. I also don't see any print statements in the console, so it looks as though the validator just isn't being run. What am I doing wrong? -
