As part of an existing add-on, I'm trying to create an object and add it to the scene using Python. I followed a Blender Cookbook tutorial found here: Three ways to create objects. I use the following code to do so:

emptyMesh = bpy.data.meshes.new('emptyMesh')
theObj = bpy.data.objects.new("object_name", emptyMesh)
bpy.context.scene.objects.link(theObj)

But I get the following error when I try to link theObj to the scene objects:

AttributeError: 'bpy_prop_collection' object has no attribute 'link'

This works just fine in Blender 2.76-2.79, but doesn't work in the 2.80 test build I downloaded. Was there a change to the Python API? Or is this maybe a bug in the test build?

    $\begingroup$ @Amir I really don't think it's necessary to change "Python in Blender" to "Blender's Python API". Either it's a general Python question in which case it's off-topic or it will be using Blender's API. $\endgroup$

In 2.8 Blender API, this is still not documented yet. After dir() inspection I've found a temporary solution, where you can replace the scene with the collection, as below: 

bpy.context.collection.objects.link(theObj)

    $\begingroup$ @justi What is dir() inspection? $\endgroup$

    $\begingroup$ @batFINGER yes, you are right - the suggested change is bpy.context.scene_collection.objects.link() but it doesn't work now. Why? Because it causes the AttributeError: 'Context' object has no attribute 'scene_collection' $\endgroup$

    $\begingroup$ @Justin I did the dir() command on the bpy.context object: dir(bpy.context) and got attributes $\endgroup$

    $\begingroup$ Yes I realize that, hence the suggestion of context.scene.collection and the query as to whether context.scene.collection and context.collection will necessarily be the same. $\endgroup$
