Question

In my django app, especially on the admin side, I do a few def’s with my models:

def get_flora(self):     return self.flora.all()  def targeted_flora(self):     return u'%s' % (self.get_flora()) 

whereas flora is a ManyToManyField, however, sometimes ForeignKey fields are used also.

I do this to provide a utility ‘get’ function for the model, and then the second def is to provide django admin with a a friendlier field name to populate the tabular/list view.

Perhaps a two part question here: 1. Is this a good workflow/method for doing such things, and 2. The resultant string output in admin looks something like:

[<Species: pittosporum>, <Species: pinus radiata>] 

Naturally enough, but how to make it look like:

pittosporum & pinus radiata 

or, if there were three;

pittosporum, pinus radiata & erharta ercta 

Super thanks!

Answer 1

Sounds like you want something like this:

def targeted_flora(self):   names= [f.name for f in self.get_flora()] # or however you get a floras name   if len(names) == 1:     return names[0]   else:     return ', '.join(names[:-1]) + ' & ' + names[-1]
