Displaying external application listview and detailview

[sunjoomoon]

Trying out https://pythonhosted.org/django-page-cms/display-content.html#display-content-from-other-applications, but I got stuck.

If I have an app, called news with model of News and want to display like below

# news.models.py
class News(models.Model):
    title = models.CharField(max_length=200)
    postdate = models.DateTimeField(default=datetime.now)
    body = models.CharField(max_length=200)

and put below in the default template, for example

# templates/pages/default-template.html
<ul>
{% for new in news %}
    <li>
        <h2>{{ news.title }}</p>
        <p>{{ news.body }}</p>
    </li>
{% endfor %}
</ul>

Put below in news.views.py

#news.views.py
..........
def extra_context():
    from news.models import News
    lastest_news = News.object.all()
    return {'news': lastest_news}

PAGE_EXTRA_CONTEXT = extra_context

In the browser, nothing is rendered. What am I missing? Normally I would tend to have models, admin(and/or forms), views, urls, templates.

Hi, most things looks correct. But just so you know PAGE_EXTRA_CONTEXT is a setting so you should put that in your settings.py file otherwise this will not work.

Alternatively you can subclass the CMS view and use you own instance of it which is probably the preferred and most flexible solution:

https://github.com/batiste/django-page-cms/blob/master/pages/views.py#L168

Just sublass the Details class based view redefine the extra_context method and use an instance of it your urls.py.

In my settings.py (project), I put below

# https://github.com/batiste/django-page-cms/issues/140
PAGE_EXTRA_CONTEXT = extra_context

Then again, browser shows below error

  File "./settings/settings.py", line 366, in <module>
    PAGE_EXTRA_CONTEXT = extra_context
NameError: name 'extra_context' is not defined

Do we have one complete example? As a newbie, working example would make more sense to me, if not all too troublesome.

Well the error is obvious, extra_context doesn't exist within the context of your settings. Add your extra_context function inside your settings (with the necessary import inside the function itself).

But this is quick and dirty solution. I strongly recommend you to subclass the Detail view.
