Django: ModelForm and show data on the same url
I'm new to django and trying to create my first app and I think I might need some little help :) I have a ModelForm on a site to submit and want to show the data on the same page. I'm having trouble to set up two functions on the same page, I think i might have to use a class and set it in urls.py but I'm not able to make it work :( the code looks like this: forms.py: from django import forms from .models import Eintrag class NameForm(forms.ModelForm): class Meta: model = Eintrag fields = ['Anmeldung', 'Essen'] urls.py from django.urls import path from . import views app_name = 'form' urlpatterns = [ path('', views.get_name, name='form'), ] views.py from django.shortcuts import render from django.utils import timezone from django.contrib.auth.decorators import login_required from .forms import NameForm from .models import Eintrag @login_required() def get_name(request): # if this is a POST request we need to process the form data if request.method == 'POST': # create a form instance and populate it with data from the request: form = NameForm(request.POST) # check whether it's valid: if form.is_valid(): eintrag = form.save(commit=False) # process the data in form.cleaned_data as required # ... # redirect to … -

Refreshing <div> in django but auto refreshing the whole template
I tried to implement the auto-refreshing using this post But the problem it refreshes the complete template instead of just refreshing the target div id. urls.py urlpatterns = [ url(r'^test/', views.test, name='test') ] views.py def test(request): acc_list = AccModel.objects.order_by('-updated') gps_list = GpsModel.objects.order_by('-updated') obj_dict = {'accVal': acc_list, 'gpsVal': gps_list} return render_to_response('appTwo/test.html', context=obj_dict) test.html ....<div id="test"> <h1>{{ gpsVal.0.latValue }}</h1> </div>..... JS Function: function refresh() { $.ajax({ url: '{% url 'test' %}', success: function(data) { $('#test').html(data); } }); setTimeout(refresh, 10000); } $(function(){ refresh(); }); Also, another problem is that no matter what value I give for "setTimeout" it refreshes very frequently. -

Django Unit Testing (with DRF): How to test a Passwordresetview?

Distributing 'clean' Django project source code
I'm currently working on a small project in Django, which I would later like to publish on github, send to someone in a zip archive etc. While testing my app, I make changes to the server to see how it behaves. Now, if I want to publish my source code, I don't want it to contain any garbage I might have generated during the development process. Basically, whoever receives the code should have a minimal, clean version of it, and at the same time should be able to work with it out of the box. What is the best way to do this? Should I make migrations before publishing my code? Are there any standard practices? -
Navigation on one site using href="#About us" does not work on smaller devices
In my django project, I am trying to build a menu for navigation on one single site. The navigation should be done by href="#about us" The menu has three sizes, one for big screens (PC), one for medium screens (Tablets), and one for small screens (Phones). The navigation works on PC size menu, but does not work on the other ones. To be clear, all of the menus redirects the user to something like mywebsite.com/info#about us, but just the PC menu actually scrolls the site. There, I fill the menus with some content from a database: {% block big-menu %} {% for faq in question_list %} <a href="#{{faq.question}}" class="w3-button w3-bar-item w3-hover-text-blue">{{faq.question}}</a> {% endfor %} {% endblock %} {% block small-menu %} {% for faq in question_list %} <a href="#{{faq.question}}" class="w3-button w3-bar-item w3-hover-text-blue">{{faq.question}}</a> {% endfor %} {% endblock %} And there is the template for the menus: <div class="w3-sidebar w3-bar-block w3-collapse w3-card w3-animate-right w3-hide-small" style="width:300px;right:0;top:0;" id="mySidebar"> <button class="w3-bar-item w3-button w3-large w3-hide-large" onclick="w3_close()"><h3>Menu &times;</h3></button> <a class="w3-bar-item w3-large w3-hide-small w3-hide-medium"><h3>Menu</h3></a> {% block big-menu %} {% endblock %} </div> <div class="w3-bar-block w3-collapse w3-animate-right w3-hide-large w3-hide-medium w3-light-gray" style="display:none;" id="smallSidebar"> <a class="w3-bar-item w3-large"><h3>Menu</h3></a> {% block small-menu %} {% endblock %} </div> And there I assign ids … -

Django admin inline issue with foreignkey
I have a model used for descriptions in different languages: class Description(models.Model): language = models.IntegerField(default=0) description = models.TextField() class Meta: db_table = 'Description' unique_together = (("id", "language"),) So this class should be used in many other classes for translating descriptions like this: class Actions(models.Model): useraction = models.IntegerField() message = models.ForeignKey('Description', on_delete=models.SET_NULL, db_column='message', null=True) class Meta: db_table = 'Actions' Then I tried to implement it in the damin.py so that I canmaintain the Actions-Model and directly the corresponding description: class DescriptionInline(admin.StackedInline): model = Description class DescriptionAdmin(admin.ModelAdmin): pass class ActionsAdmin(admin.ModelAdmin): inlines = [ DescriptionInline, ] But that trows the following exception when running the server: ERRORS: : (admin.E202) 'manageta.Description' has no ForeignKey to 'manageta.Actions'. Since I use the Description-Model for multiple other models I cannot set the foreignkey from it the other models but the other way around like shown above. Can anybody tell me what I did wrong? Thanks Key -
Django channels integrating with django
I'm following django channels tutorial in order to integrate it with django. But, at one point I confronted with error which I can't solve. In terminal Django says: [Errno 111] Connect call failed ('127.0.0.1', 6379) I think that problem is about with these lines in tutorial: We will use a channel layer that uses Redis as its backing store. To start a Redis server on port 6379, run the following command: $ docker run -p 6379:6379 -d redis:2.8 I'm working in Linux Ubuntu 17.04 and can't run command shown in above. When I run that command ubuntu terminal says: docker: command not found Result is still the same after installing 'docker' with 'sudo apt-get install docker'. How can I solve this problem? Is there other way to start redis server on specified port without installing docker? -

I have about 500k domain records and 3kk ToolResults records. That makes not possible to iterate objects. How do I can do this effective ? -
When attempting to save from a serializer getting error - Unable to get repr for class
I ma trying to understand why I am getting the error for my serializer Unable to get repr for <class 'Job.models.modelJob'> This is what my job looks like class modelJob(models.Model): employer = models.ForeignKey(modelEmployer,on_delete=models.CASCADE,null=True,default=None,blank=True) title = models.CharField(max_length=200, unique=False,blank=False,null=True) moreInfo = models.CharField(max_length=500, unique=False,blank=False,null=True) imageA = models.ImageField(upload_to='images/', default='',null=True) imageB = models.ImageField(upload_to='images/', This is what I am posting to it { "title" : "Plumbing", "moreInfo" : "A", } This is my serializer class Serializer_CreateJob(serializers.ModelSerializer): class Meta: model = modelJob fields = [ 'title', 'moreInfo', ] This is my view class Test_CreateAPIView(CreateAPIView): serializer_class = Serializer_CreateJob permission_classes = (permissions.AllowAny,) def post(self, request, format=None): emp = modelEmployer.objects.all()[0]; serializer = self.serializer_class(data=request.data) if serializer.is_valid(): modeljob = serializer.save();#------>Not getting back the object return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) From what I understand modeljob = serializer.save(); is suppose to return back a created object but it doesnt. I know i can overwrite create(self, validated_data) and return back an object but in this case I would simply like to create an object. Why is save() not returning back an object ? Any suggestions ?
