PODjango model inheritance w/ custom inclusion_tags
text
Body
copied!<p>I'm gonna try and simplify this as much as possible. Lets say i have the following:</p> <h1>models.py</h1> <pre><code>class Person(models.Model): name = models.CharField(max_length=255) def getRealPerson(self): # is there a better way to do this? ret = None try: ret = self.worker except: try: ret = self.retired except: ret = self return ret class Worker(Person): salary = models.IntegerField(default=0) class Retired(Person): age = models.IntegerField() </code></pre> <p>The example doesn't really matter for what I want, just go with me here. The purpose of this is so I can have a master Person table to reference all people.</p> <p>Ideally I want to be able to call a view of Person's and have each ones specific details listed in a custom way for each class type. I'd like to use a custom inclusion_tag to do this.</p> <h1>people.html</h1> <pre><code>{% load people_extras %} {% for person in people %} {% show_person person %} {% endfor %} </code></pre> <h1>people_extras.py - templatetags</h1> <pre><code>from django import template @register.inclusion_tag('worker.html') def show_worker(person): return {'person':person} @register.inclusion_tag('worker.html') def show_retired(person): return {'person':person} #How do I write this function and use it as the show_person person tag? from project.app.models import Worker, Retired def show_person(person): person = person.getRealPerson(): if isinstance(person, Worker): return show_worker # yes, this doesn't work. </code></pre> <p>I have no idea how to get it to call the correct template based on the person type.</p> <p>I couldn't figure out how to accomplish this with the template using {% ifequal %} like this:</p> <pre><code>{% ifequal person.getRealPerson.__class__.__name__ "Worker" %} {% show_worker %} ... </code></pre> <p>I went the route I wrote above with the templatetags. However, I dont know where to put the logic to determine the person type!</p> <p>I think eventually I'd like to be able to use a generic view for this as well on the Person object.</p> <p>If there's a far better way to do this, I'm open to suggestions, I just want to get it working.</p> <p>I've been kinda stuck here for over a day... could really use a push.</p>
