How to display data with value '0' in chart with chart.js?
I have a chart of 3 data-Chinese Book, English Book, Malay Book. Chinese book has 300, English Book has 400, Malay Book has 0. It works fine when I only display Chinese Book and English Book. When I add in Malay Book for display, it doesn't return errors but displays nothing. Here is my function for bar chart, function setChart(){ var ctx = document.getElementById("avgPageCount"); var avgPageCount = new Chart(ctx, { type: 'bar', data: { labels: {{ chartdata_labels|safe }}, datasets: [{ label: '# of votes', data: {{ chartdata_data }}, backgroundColor: {{ chart_bg | safe }} , borderColor: {{ chart_bd | safe }}, borderWidth: 1 }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero:true } }] } } }); } window.onload = setChart; Malay book will return 0 since there is no new register book for this month. malay_book= Book.objects.filter(reg_date__range(current_month_first_day,today)).aggregate(Sum('total'))['total_sum'] _out_label.append('Malay Book') _out_data.append(malay_book) Is the chart won't display value with '0'? -

I have React with MobX function not working in the order I expect. Any Ideas?
I am working on a React project the I am using Mobx for stores. I am getting the store to work right I am saving data without any problems. The one problem I am running into is I call a couple of functions and it seems to be they are being run backwards and I can not figure it out. I will list the code below, if someone could look at it with fresh eyes and tell me what I am missing. Main .js file componentDidMount(){ const query = parse(location.search); if (query.slug !== undefined) { this.props.IftaStore.getTruck(query.slug); this.props.IftaStore.load(); } else { this.props.IftaStore.setLimitByTruck(false); this.props.IftaStore.load(); } } I basically have a url get that I am getting called slug. I parse that then if it is not undefined I call a function called getTruck in my store (see below). Once getTruck is run then the function load should be called (also in the store). What seems to be happening is load is running then getTruck. store code: getTruck = async user => { const thisConst = this; let endpoint = '/api/equipment/truck/?driver=' + user; let lookupOptions = { method: "GET", headers: { 'Content-Type': 'application/json' } }; let data = []; try { const response … -

Django DateField format impossible to validate and save to model
Old issue, I know. But I still could not find a working solution so I may have missed something obvious.

Django change Models relations depending on condition (if is staff or not)
I have 2 Moles, User and Account. The User can be staff or normal User. In general a User can have just one Account. This is what I have now: class User(AbstractBaseUser): account = models.OneToOneField(Account, null=True, on_delete=models.CASCADE) but in special cases an User can have multiple or no Account, only if the User is_staff. The logic is to have now a ForeignKey: class User(AbstractBaseUser): account = models.ForeignKey(Account, on_delete=models.CASCADE) But in this case, how do I stop in Django Admin or else, for a User to have multiple Foreign keys if is not staff, and force it for normal users to have a simulated OneToOne Relation. -

How to leave ManyToManyField attributes selected automatically as default? Django 1.10
In the system that is part of the development, there is a field of "authors" in the models that is a ManyToManyField, in which some users of the database are extracted in which the content of the site will be published.
