How to use "Reference" field?

Question

"Add an Element" -> "Field" -> "Reference" has the same help text than "Selection" but should work to get values from other model. Any hint how to use it?

Hi,
*Reference* fields are used to add dynamic relations on a model. In normally used relational fields like Many2one, One2many & Many2many, we pre-define the related target model( comodel), so it allows only relation between those two models. But if we use the *Reference *field type, it allows the user to choose related model from a Selection list & then choose a related record on that selected model.
For example, you may refer the subcription module in Odoo 10, goto *subscription>>models>>subs

Hi ulrich,
i dont think you can provide a string to the selection value. _get_document_types in
*subscription>>models>>subscription.py*
returns a list of tuples.
make a funktion
def _get_krempel(self):
return [('MODEL1','NAME1'),( ('MODEL2','NAME2' ),( ('MODEL3','NAME3' )]

Hi, may I renew the question on how the the string has to look like which is written into the "Selection" field. In order words, how do the ('key','Label') pairs look like? Should the key represent the model and Label be just a string, such as [('model1','Name1'), ('model2', 'Name2'),....] and so on? Above answer does not really solve the issue.
Thank you in advance
