** Background ** In the admin view, I want to generate a form which grabs a list of items from the database and displays a checkbox next to each item. The goal is simply to check multiple boxes and hit Submit and they are deleted.
Because of the way my models are setup, there is no default admin view for this. I couldn't figure out how to get change_list.html to display the item info, so I am trying to write my own (it's good practice anyway). *** My questions: 1) I don't understand how the InventoryFieldModel fields get populated in the database. Do I need to do this explicitly? Or is the get_inventory_form() function handling it? 2) How do I add the checkboxes to each listed item? 3) Inside the view function, if I "print form.as_p()" nothing is returned. Is this because I didn't populate the database correctly? Or am I calling get_inventory_form() with not enough keywords? >From what I understand, get_inventory_form is supposed to take the samurai instance, get the inventory objects associated with him from the db, and create a form field for each item in the inventory. *** Following: http://uswaretech.com/blog/2008/10/dynamic-forms-with-django/ I added the information noted below. *** My code *** ** models.py ** type_mapping = {'CharField':forms.CharField(max_length = 100), 'TextField': forms.CharField(widget = forms.Textarea), 'BooleanField':forms.BooleanField(required = False), 'URLField': forms.URLField(), 'EmailField': forms.EmailField() } class InventoryFieldModel(models.Model): samurai = models.ForeignKey('Samurai') item = models.ForeignKey('Item') condition = models.IntegerField() ** forms.py ** def get_inventory_form(samurai): inventory_fields = InventoryFieldModel.objects.filter(samurai=samurai).order_by('item') class InventoryForm2(forms.Form): def __init__(self, *args, **kwargs): forms.Form.__init__(self, *args, **kwargs) self.samurai = samurai def save(self): # do the save pass for field in inventory_fields: setattr(InventoryForm2, field.name, copy(type_mapping[field.type])) return type('InventoryForm2', (forms.Form, ), dict(InventoryForm2.__dict__)) ** admin_views.py ** def remove_item_from_samurai(request, samurai_id): samurai = Samurai.objects.select_related().get(pk=samurai_id) inv = Inventory.objects.select_related().filter(samurai=samurai_id).order_by('item') inventory_form = get_inventory_form(samurai) if request.method == 'POST': form = inventory_form(request.POST) if form.is_valid(): ## process data and delete items return HttpResponse("ok") else: form = inventory_form() return render_to_response("admin/myapp/samurai/remove_item.html", { 'samurai': samurai, 'inv': inv, 'form': form }) ** remove_item.html ** <form action="" method="post"> <table> {{ form.as_table }} </table> <input type="submit" value="Delete" /> </form> -- You received this message because you are subscribed to the Google Groups "Django users" group.
