Image sometimes does not display in HTML page (Django 3.0)
I created a somewhat clone of Instagram main page (for full transparency, please know that I do this for a psychological experiment). One of my users got a very strange bug : when going on my page, two images seemed to not be loaded (there was no broken link, and the images simply appeared to be skipped, see illustration below). Images not displaying illustration On reloading the page, the images indeed appeared normally, and other users did not get any bug. The thing is, I do not quite understand how this could happen, since I show the page only when all resources are loaded, through these lines of code : window.addEventListener('load', function () { document.getElementById("main-page").style.visibility = "visible"; }); Please find the code for the page below (I removed navbar code for lisibility, please let me know if full version is needed). <body id="main-page" style="visibility:hidden"> <section class="main"> <div class="wrapper"> <div class="left-col"> {% include 'instapp/status.html' %} {% include 'instapp/post.html' %} </div> <div class="right-col"> {% include 'instapp/recommandations.html' %} </div> </div> </section> <script> window.addEventListener('load', function () { document.getElementById("main-page").style.visibility = "visible"; }); </script> </body> And here is the code for displaying a single post : {% load static %} <div class="post"> <div class="info"> <div class="user"> … -
Django table connection based on the value type
I really want some help with this problem, because somehow I cannot solve it. The problem: I have a Parameter table, which is stores parameters I want to store the values in different parameters, based on the type of the parameter These are the type models: class JsonParameter(models.Model): value = models.JSONField() class StringParameter(models.Model): value = models.CharField(max_length=100) class DateParameter(models.Model): value = models.DateField() And I have a parameter model: class Parameter(TimeStampedModel): name = models.CharField(max_length=64) is_mandatory = models.BooleanField(default=True) value = SomekindOfMagic() So if I would like to create some parameters, like this param_1 = Parameter.objects.create(name="name of the param", is_mandatory=True, value="This is a string value") param_2 = Parameter.objects.create(name="name of the param", is_mandatory=True, value='{"object": "string"}') param_3 = Parameter.objects.create(name="name of the param", is_mandatory=True, value="2022-03-20") The param_1.value will be saved into the StringParameter table, the param_2.value will be saved into the JsonParameter table, and the param_3.value will be saved into the DateParameter table and the Parameter.value will contain a foreign key like object. Can I use the generic foreign key for this? Or do I have to use something else ? There is any solution for this ? Thanks guys :) -

How to compare multiple lists in order in django template
I have an "Educate" class model, which consists of fields such as class name, class description, and the teacher in charge of the class. And I have a "History" class model, which is written to the database whenever the contents of the "Educate" class change. Every time the teacher in charge of Educate changes, it is tracked in the "History" class model, and what I want to get is the duration of each teacher. The "History" class model has a "summary" field, in which the contents of the changed fields are stored. If I check in DB, it is as below, and you have to load json format from template to output as string. DB: {"field_summary": {"teacher": "\ub...json...9bc -> \ub...json...9c", "contact": "010-1111-1111-> 010-0000-0000"}, "file_summary": {}} [educate/models.py] class Educate(models.Model): educate_name = models.CharField(max_length=2000, null=True) educate_explanation = models.CharField(max_length=2000, null=True) teacher = models.ManyToManyField(Contact, related_name="teacher") @property def history(self): history = self.history_set.all().order_by('-create_date') for h in history: setattr(h, 'summary_json', json.loads(h.summary)) return history class History(models.Model): educate = models.ForeignKey(Educate, on_delete=models.SET_NULL, null=True, blank=True) summary = models.TextField(blank=True, null=True) create_date = models.DateTimeField(auto_now_add=True) def json(self): return { 'id': self.id, 'educate': { 'id': self.educate.id, 'educate_name': self.educate.educate_name, 'educate_explanation': self.educate.educate_explanation, }, 'summary': self.summary, 'create_date': self.create_date } [educate/views.py] def statistic(request): educate = Educate.objects.get(id='117') return render(request, 'statistic.html', {'educate': … -
