Question

I use mongoengine, and love it very.
now I work it with django, and I get a problem with it
how to set property for ListField
e.g.
this was my model

class Bussiness(Document):
    tags = ListField(StringField())

and I want to use it on template like this:

{% for tag on bussiness.tags %}
    {{ tag.url }}
{% endfor %}

but the tag.url I don’t want to save it to database, just hope to produce it on model level, and make tags only some string on database.
And if I hard code it on template, I have to write it everywhere, that was I disgust.

This wont work as tag is just a string (you have it defined as a StringField).

You could have tag as an embedded document with url being a property eg:

class Tag(EmbeddedDocument):
    name = StringField()

    @property
    def url(self):
        return "http://my-ace-site.come/businesses/%s/"

class Business(Document):
    tags = ListField(StringField())
