Datatable ajax add row on condition
So I'm having some trouble setting up datatable using Ajax. Some context: I have a Ajax that request certain files information. The response contains two sets The files information The users information (to figure out the user of the files).

I have 2 condition Is the end date between today and 4 days from now? is the end date after 4 days form now? These condition are used to indicate to the user witch files (project) needs the most attention. CODE TIME (I'm using the Django framework btw) :D The AJAX CALL function ajax_dates() { $.ajax({ url: "{% url 'get_files_dates' %}", type: "GET" }).done(function (object) { date_calculation(object.dates, object.users); }); } THE TWO CONDITION // CONDITION ONE (ATTEMPT using Datatable) // Projecten met een waarschuwing if (enddate.isBetween(today, today.clone().add(4, 'd'))) { // TABLE ROW VOOR ELK TYPE running_waring = ""; running_waring += '<tr>'; running_waring += '<td>'+ checker.first_name + " " + checker.last_name+'</td>'; running_waring += '<td>'+ checker.first_name + " " + checker.last_name+'</td>'; running_waring += '<td id="testing">'+result.name+'</td>'; running_waring += '<td>'+result.word_count+'</td>'; running_waring += '<td>'+enddate.format("D MMM YYYY").replace(".","")+'</td>'; running_waring += '<td>'+enddate.format("HH:mm:ss")+'</td>'; running_waring += '<td>Verloopt binnenkort </td>'; running_waring += '<td> Verloopt' + … -

Signup page stuck on loading (Waiting for Localhost...) after extending AbstractUser
I created a custom user model called Agent by extending AbstractUser. Now for some reason, my signup page is stuck and I can't figure out why (it was working fine before I created the custom user). When I click the Sign Up button, the page is stuck on Waiting for localhost... There are 2 additional models on top of Agent that are created during registration - AgentBasicInfo and AgentPremiumInfo. AgentBasicInfo is displayed on the sign up page, while AgentPremiumInfo is created in the background, and not actually displayed during registration. When I check my admin page, I see that an Agent model has been created, but no AgentBasicInfo and AgentPremiumInfo instances have been created. This leads me to believe something is getting stuck at or after agent_basic_info = basic_info_form.save(commit=False), but I can't figure out what it is. Here is my code: views.py def signup(request): if request.user.is_authenticated: return HttpResponseRedirect('../dashboard/') if request.method == 'POST': signup_form = SignupForm(request.POST) basic_info_form = AgentBasicInfoForm(request.POST) if signup_form.is_valid() and basic_info_form.is_valid(): agent = signup_form.save(commit=False) agent.is_active = False agent.save() # Creates a basic info form with user input agent_basic_info = basic_info_form.save(commit=False) agent_basic_info.agent = agent agent_basic_info = agent_basic_info.save() # Creates a profile model with the agent's premium information, empty except for … -

django oscar migrations not migrating, other app migrates
I've been quite stuck and I've read the docs over and over again. My models aren't migrating. My prompt would be No changes detected in app "catalogue" but I did make changes. I can't seem to figure out what I'm doing wrong. Sometimes it works and I don't know why. I make note of it and repeat it, it doesn't work. Any suggestion or idea is appreciated. Thanks!!! subapp1 is the shop app using oscar, subapp2 is another app I run python manage.py makemigrations catalogue then python managepy migrate catalogue I've also tried migrating in the subapp1.

Graphene-django returns null node instead of just node field
I am facing a strange problem with graphene and Django. The documentation seems to lack a solution and I couldn't figure out what I'm doing wrong. I have the following models: Class Sentence(models.model): ref = models.CharField(max_length=30, primary_key=True) body = models.TextField(default=None) Class Summary(models.Model): sentence = models.ForeignKey(Sentence, on_delete=models.CASCADE) text = models.TextField(default=None) (Each sentence can have multiple summaries) And the following schema: Class SentenceType(DjangoObjectType): class Meta: model = models.Sentence filter_fields = {"ref": ["exact"]} interfaces = (graphene.Node, ) Class SummaryType(DjangoObjectType): class Meta: model = models.Summary filter_field = {"text": ["icontains"]} interfaces = (graphene.Node, ) Class Query(graphene.ObjectType): all_sentences = DjangoFilterConnectionField(SentenceType) sentence = graphene.Field(SentenceType, ref=graphene.string(), body=graphene.string()) all_summary = all_provvedimenti = DjangoFilterConnectionField(SummaryType) summary = graphene.field(SummaryType, id=graphene.Int(), text=graphene.string()) def resolve_all_summaries(self, context, **kwargs): return models.Summary.objects.all() It can occur that there is one or more summaries in my database with no corresponding sentence. Now, when I query { allSummaries{ edges{ node{ text sentence{ ref } } } } } If the the sentence exists for the summary, no problem at all. But if there is no corresponding sentence I get: "errors": [ { "message": "Sentence matching query does not exist.", "locations": [ { "line": 6, "column": 9 } ] } ], ..., ..., "data":[ ..., { "node": null }, { "node":{ … -

How to test a Django CreateView
I want to practice testing on Django, and i have a CreateView i want to test. The view allows me to create a new post and i want to check if it can find posts without a publication date, but first i'm testing posts with published date just to get used to syntax.

Reduce amount of queries for generic foreign key

Is there a way to set meta data (Title and Description) for login_required pages?
Google is indexing my login_required pages, but it seems as though they are just pulling the title from the link that lead them to the page and then indexing the login form that the page redirects to?

Search · About · Contact · FAQ · Privacy ..." Is there a way to set the meta data for these pages? Or should I just restrict Google from crawling them at all to keep from getting a penalty? -
