阅读更多关于 Python datastructures into js datastructures using Django templates (lists and dicts)

问题 I have a Django view that returns a list of dicts like so data = [{'year': 2006, 'books': 54}, {'year': 2007, 'books': 43}, {'year': 2008, 'books': 41}, {'year': 2009, 'books': 44}, {'year': 2010, 'books': 35}] c = { 'data': data, } return render(request, 'template.html', c) The template file has some basic JavaScript in it that does something like this. var data = "{{data}}"; console.log(data); //..... Then other functions The issue is that the data is coming into the JavaScript via the

Django template tag to insert or replace URL parameter

阅读更多关于 Django template tag to insert or replace URL parameter

问题 Is anyone aware of a Django template tag that takes the current path and query string and inserts or replaces a query string value? e.g. given a request to /some/custom/path?q=how+now+brown+cow&page=3&filter=person The call {% urlparam 'page' 4 %} would generate /some/custom/path?q=how+now+brown+cow&page=4&filter=person . This wouldn't be too difficult to write from scratch, but as this seems like a very common task, I would expect a tag like this to be built-in. However, after reading

问题 I have been looking at this tutorial and now have a stylesheet in /static/styles/ . The problem is that the template doesn't pick this up: <html> <head> <link rel="stylesheet" type="text/css" href="static/css/stylesheet.css" /> <title>Search</title> </head> <body> ... Do I need something in my settings file? Where am I going wrong? My project structure is: project - manage.py - project - static - templates - __init__ - etc.. EDIT My urls.py now looks like this: from django.conf.urls import

问题 forms.py class ImportExcelForm(Form): file = forms.FileField(attrs={'class':'rounded_list',}) I am trying to add css class to my filefield in forms.I am getting this error "__init__() got an unexpected keyword argument 'attrs'" What i did wrong. Thanks 回答1: attrs is not an argument to the field, it's an argument to the widget. file = forms.FieldField(widget=forms.FileInput(attrs={'class': 'rounded_list'})) Note that some browsers don't allow styling of the file input. 来源： https:/

django forms error_class

阅读更多关于 django forms error_class

问题 Is there a way to give a form a special error rendering function in the form definition? In the docs under customizing-the-error-list-format it shows how you can give a form a special error rendering function, but it seems like you have to declare it when you instantiate the form, not when you define it. So you can define some ErrorList class like: from django.forms.util import ErrorList class DivErrorList(ErrorList): def __unicode__(self): return self.as_divs() def as_divs(self): if not self

Django custom 500 error template not displaying request.user

阅读更多关于 Django custom 500 error template not displaying request.user

问题 I'm implementing custom 404 and 500 templates, but while the 404.html template seems to return request.user.is_authenticated fine, the 500.html template fails to return anything. I also checked for request.user and it's just blank on the 500 page. This is very strange, because when I trigger the 500 error, I receive the expected error report e-mail, and it clearly has USER properly defined in the request breakdown. Here's the code I'm using in views.py: def handler404(request): response =
