I use the Drupal Commons distribution. I already created blog-post depends under group section using OG_MEMBERSHIP. Likewise, blog-post depends under content type event. How to achieve this?
We also have some event section (with particular time/date and location), which is used for maintaining some blog-post (content type).
Can anyone provide some insight about how to do this? I.e some procedure or modules for creating such blog-post (content type) under event.
Not sure if I correctly understand the question, but it sounds to me that using the Entity Reference module might be the solution you are looking for. Here's a quote from the module's project page:
Provides a field type that can reference arbitrary entities
Another option is to consider the References module, which provides D7 versions of the 'node_reference' (and 'user_reference') field types, that were part of the CCK package in D6.
If these module don't help for what you're trying to achieve, then reviewing the amazing set of videos to Learn Organic Groups might help somehow.
