generic views django

  • from django.conf.urls.defaults import * from django.views.generic import list_detail from mysite.books.models import Publisher publisher_info = { 'queryset': Publisher.objects.all(), 'template_name': 'publisher_list_page.html', } urlpatterns = patterns('', (r'^publishers/$', list_detail.object_list, publisher_info) )
  • That’s really all there is to it. All the cool features of generic views come from changing the “info” dictionary passed to the generic view.
  • You might have noticed that sample publisher list template stores all the books in a variable named object_list.
  • ...10 more annotations...
  • it isn’t all that “friendly” to template authors: they have to “just know” that they’re dealing with books here.
  • better name
  • publisher_list;
  • 'template_object_name': 'publisher',
  • If you want to present a list of books by a particular publisher, you can use the same technique:
  • Another common need is to filter the objects given in a list page by some key in the URL. Earlier we hard-coded the publisher’s name in the URLconf, but what if we wanted to write a view that displayed all the books by some arbitrary publisher?
  • “wrap” the object_list generic view
  • # Look up the publisher (and raise a 404 if it can't be found). publisher = get_object_or_404(Publisher, name__iexact=name)
  • Notice that in the preceding example we passed the current publisher being displayed in the extra_context. This is usually a good idea in wrappers of this nature; it lets the template know which “parent” object is currently being browsed.
  • Or, you could use a less obvious but shorter version that relies on the fact that Book.objects.all is itself a callable:

  • Big list of Django tips
  • Writing managers is really simple, and they provide a better user interface to your code. This code snippet simply adds a latest() method to the default objects manager class ForecastDayManager(Manager): def __init__(self, *args, **kwargs): super(ForecastDayManager, self).__init__(*args, **kwargs) def latest(self): return self.get_query_set().order_by('forecast_date')[0] It can be called ForecastDay.objects.latest(). This is a trivial example, but there is a lot of power that lies in this functionality.

  • 1. What am I trying to say? 2. What words will express it? 3. What image or idiom will make it clearer? 4. Is this image fresh enough to have an effect? And he will probably ask himself two more: 1. Could I put it more shortly? 2. Have I said anything that is avoidably ugly?
  • What is above all needed is to let the meaning choose the word, and not the other way around.
  • When you think of a concrete object, you think wordlessly, and then, if you want to describe the thing you have been visualizing you probably hunt about until you find the exact words that seem to fit it. When you think of something abstract you are more inclined to use words from the start, and unless you make a conscious effort to prevent it, the existing dialect will come rushing in and do the job for you, at the expense of blurring or even changing your meaning
  • ...1 more annotation...
  • (i) Never use a metaphor, simile, or other figure of speech which you are used to seeing in print. (ii) Never us a long word where a short one will do. (iii) If it is possible to cut a word out, always cut it out. (iv) Never use the passive where you can use the active. (v) Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent. (vi) Break any of these rules sooner than say anything outright barbarous.
