Aldryn Blog Placeholder Missing

[sraddhanjali]

I have installed the aldryn_blog and all its requirements. I have created a page and added the hook "blog" and now the page is a blog app. However, when I go to the structure of the page, I see no placeholder as mentioned in the documentation "ALDRYN_BLOG_POST_CONTENT". I think there is some documentation missing so please look at it.

This are the installed_apps for aldryn_blog.

'aldryn_blog',
'aldryn_common',
'django_select2',
'djangocms_text_ckeditor',
'easy_thumbnails',
'filer',
'hvad',
'taggit',
# for search
'aldryn_search',
'haystack',

Haystack connections have been added as:

 HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
        'URL': 'http://127.0.0.1:8983/solr'
        # ...or for multicore...
        # 'URL': 'http://127.0.0.1:8983/solr/mysite',
    },
}

Also, it shows Blog, no posts yet only when the page is published, not when it is in Draft.
