Possible duplication with nodereference_autocreate

They are different. This module combines the autocomplete functionality with the ability to create nodes that don't exist. Nodereference_autocreate can create new nodes, but it cannot reference existing ones.

I feel like this module will get a lot of similar questions, so I'm dedicating this one to nodereference_autocreate.

Nodereference_autocreate can create new nodes, but it cannot reference existing ones

I'm sorry, but that quote begs the question: Doesn't Node reference itself refer to existing nodes, meaning that you don't need an addon for that?

The normal workflow with a 'create-node-on-the-fly' module available:

1. Content type A has a node reference field associated with Content type B.
2. I create a new node of type A, add relevant data and reach the node reference field. Either of two things can happen.

a) the node I need to refer to is already existing, I select it and move on (this happens either via 'select list' option or 'autocomplete' option of the normal node reference field).
b) the node I need to refer to does not exist, I create the node of Content type B on the fly using either of the two modules in question.

3. I finish creating the original node of type A.

This leads to me repeating the question: What is the difference between the two modules.

(note: I'm not biased towards either of them, I'm really and truly wondering which one of them to use for my own project).

To follow up on my own comment. There's a thread over at Autocreate Node Reference that gives an idea of what the difference is.

As I understand it, the other one deals with automatic creation of template-clones based on given criteria setup by the admin, while this module deals with automatic creation of a node (with a reference to the original one, setup by the user) that would be in a select list of a "normal" node reference field, had it been created earlier.

Is this a correct understanding?
If so, I suggest that the authors of both modules coordinate their comments and explanations and redirect users between them accordingly - because, then there's quite a difference between the two.

@elfur: Your understanding seems fine. Thank you for investigating the similarities and noting them here.

The differences of these two modules is also discussed in another issue for nodereference_autocreate: #494556: choose to create a new node or a created one.
