django how to loop through the context object passed back by a generic detailview?

问题

I'm using a generic DetailView to display a project object. Can I loop through the fields somehow in my template or do I have to place every field.

url(r'^(?P<slug>[-\w]+)/$', DetailView.as_view(model=Project,
                                               template_name='projects/detail_project.html',slug_field='slug',
                                                context_object_name='project'), name='project_detail'),

I've got something like this in my template:

{{ project.title }}
{{ project.created_date }}

etc...

Is there a way to do something like this?

    <table>
        {% for field in project %}
            <tr>
                <td>{{ field }}</td>
            </tr>
        {% endfor %}
    </table>

I tried the above snippet and got this error:

Caught TypeError while rendering: 'Project' object is not iterable

回答1:

Usually its best to place each field, but ff you just want to dump all the fields you would could do something like:

# models.py
class Project(models.Model):
    ...

    def get_field_values(self):
        return [field.value_to_string(self) for field in Project._meta.fields]

then you could do

<table>
    {% for value in project.get_field_values %}
        <tr>
            <td>{{ value }}</td>
        </tr>
    {% endfor %}
</table>
