Function-based generic views have been deprecated

阅读更多关于 Function-based generic views have been deprecated

问题 DeprecationWarning: Function-based generic views have been deprecated; use class-based views instead. I keep getting this warning, when I'm running my site. What does this mean and how can I fix it? 回答1: Django 1.3 introduced class-based views and also added a range of generic class-based views. Django also has documentation about migrating function-based views to class-based views. There is not really much more to say about it: your project currently uses function-based views whereas class

How do I display most recent week items by default with WeekArchiveView?

阅读更多关于 How do I display most recent week items by default with WeekArchiveView?

问题 I'm astonished by how little documentation on class-based generic views there is. Anything slightly more complex than a trivial sample has to get done through guesswork, trial and error. I want to use WeekArchiveView to display a week's item list. There's my urls.py entry: url(r'^items/(?P<year>\d{4})/week/(?P<week>\d{1,2})/$', ItemWeekArchiveView.as_view()) When no year or week is specified, I get an error page. I want them to equal today's year and week by default. What is the right place

How do I paginate WeekArchiveView?

阅读更多关于 How do I paginate WeekArchiveView?

问题 In continuation of my struggle with WeekArchiveView, how do I paginate it by week? All I want is: to know if there is next / previous week available; in case there is, provide a link in the template. I'd like it to also skip empty weeks. The source shows get_next_day / get_prev_day and get_next_month / get_prev_month are available, but nothing for weeks. 回答1: That is definitely interesting. Sure enough MonthMixin includes get_next_month / get_prev_month methods, and DayMixin includes get_next

问题 I am looking for a simple answer by example to this common problem. The answers I found so far leave out critical points for us beginners. I have an app where almost every model has a ForeignKey to User, and there is a unique_together constraint, where one of the fields is always 'user'. For example: class SubscriberList(models.Model): user = models.ForeignKey(User) name = models.CharField(max_length=70) date_created = models.DateTimeField(auto_now_add=True) class Meta: unique_together = ( (

问题 I have a little project created with django1.3 and I want to migrate it to django1.4 but since the files structure change a little, what is the best way to migrate? 回答1: Read https://docs.djangoproject.com/en/dev/releases/1.4/ first.

For a clean update, better to create an empty project w/ the same name of the current project and migrate it w/

How to specify something other than pk or slug for DetailView

阅读更多关于 How to specify something other than pk or slug for DetailView

I was wondering if it was possible to use something besides a pk or slug when you are using a DetailView in Django 1.3. For example, I currently have: url(r'^mymodel/(?P<pk>\d+)/$', MyDetailView.as_view()) as my url. Say I wanted something like: url(r'^mymodel/(?P<name>\d+)/$', MyDetailView.as_view()) where name would be a field in the model. Is there anyway to have the DetailView use that to 'grab' the object I want and pass it on to my template? A slug doesn't have any particular significance in Django. It's just a name for a field that identifies a row. If your slug is called something else

how to get POST data in django 1.3

Hey, I am following this tutorial to learn to make a wiki page with Django. However, it is made in django 0.96 and I use Django 1.3 so there are some things that are different. Some I already fixed myself, however this one I can't seem to make it work. I made a form that submits data to a view. This is the form: <form method="post" action"/wikicamp/{{page_name}}/save/">{% csrf_token %} <textarea name="content" rows="20" cols="60">{{content}}</textarea><br> <input type="submit" value="Save Page"/> </form> and the /wikicamp/{{page_name}}/save/ url redirects to the save_page view: from django
