问题 I want to be able to set variables in a template to string values. I wrote a tag, but it doesn't seem to change the context. The intended use is: {% define "a string" as my_var %} Update (solved): class DefineNode(Node): def __init__(self, var, name): self.var = var self.name = name def __repr__(self): return "<DefineNode>" def render(self, context): context[self.name] = self.var return '' @register.tag def define(parser, token): """ Adds a name to the context for referencing an arbitrarily

问题 I've just start to learn Django and now I'm trying understand how to insert datas in db, how to work with datas from templates and ect. My question is about extracting datas from form(Meta class) in template. Here is my code: model class Worker(models.Model): POSITION_SHOICE = ( ('MANAGER', 'MANAGER'), ('developer', 'DEVELOPER'), ('teamlead', 'TEAMLEAD'), ('pm', 'PM'), ('hr', 'HR'), ) f_name = models.CharField(max_length=50) s_name = models.CharField(max_length=50) position = models.CharField

问题 In the beginning everything worked perfectly fine, but now I have a problem where my static files doesn't load. I think this is a very weird problem since I didn't really touch anything that could've had an influence on the problem when it happened. Everything else is working fine, I just can't get the static files for some reason. I sometimes get a 200 http response trying to get the static files like so: [20/Aug/2020 16:12:51] "GET /order/checkout/ HTTP/1.1" 200 2029 [20/Aug/2020 16:12:51]

问题 So I spent the weekend testing and searching SO and finally got Django and Chart.js working. Kind of. It renders the graph but the data is not correct. When I loop through the object, the results are not what I would expect. Maybe I'm blind from staring at this all weekend. Would appreciate any pointers. Here are my views... class ChartView(LoginRequiredMixin, TemplateView): template_name = 'Books/chart.html' def get_context_data(self, **kwargs): context = super(ChartView, self).get_context

问题 I want to display products in a Campaign DetailView template. In my project each campaign has a shop which contains products, so the flow is like, Campaign --> Shop --> Products Campaign models.py class Campaign(models.Model): team = models.OneToOneField(Team, related_name='campaigns', on_delete=models.CASCADE, null=True, blank=True) shop = models.OneToOneField(shop_models.Shop, on_delete=models.CASCADE, null=True, blank=True) Shop models.py class Product(models.Model): title = models

问题 I added a Django form to my Bootstrap nav bar to be included on every page, and it renders as it should with the appropriate values. The form was added using an inclusion_tag. However, I'm now at a loss as to how to handle the request from the form. Upon submission, whichever page the user was on should reload with updated content from the form submission. For more context, see my earlier question: How to place a django form in a nav bar so that it appears on every page? 回答1: Answering my own
