Question

I have a model with ContentType field in it.

In any model method I can compare it to the string:

self.content_type == "construction" # True if ContentObject points to Construction model.

However, such thing doesn’t seem to work in templates.

First thing I tried

{% if object.content_type == "construction" %}

And second:

def __unicode__(self): 
    return str(self.content_type)
`{% if object == "construction" %}`

and it’s False, but {{ object }} prints construction.

Answer 1

The unicode method for ContentType simply displays the name, which is why {{ object }} displays construction in the template.

class ContentType(models.Model):
    ...
    def __unicode__(self):
        return self.name

However, object.content_type is a ContentType instance, not a string, so comparing it to “construction” will always return False. Try comparing the content type’s model instead.

{% if object.content_type.model == "construction" %}
