one2one fields in views

Question

I have a need for a one2one relationship between project.project and crm.lead and display the link in each object's form view. I have put my many2one field into crm.lead and added it to the Opportunity Form View. I now need to do the same thing to the Project Form View, but the only way I can get that relationship to display is by using a one2many field in project.project. I saw in other forum posts that _inherits need to be set, however when I do that and put the field in my view I get "Automatically created field to link to..." in the label section and no value.

Has anyone successfully created this one2one relationship with links in the object views?

The closest I came to achieving this was adding a many2one field on crm.lead and a functional field on project.project that returns the corresponding crm.lead (if there is one).

Hi,
I am unsure if it helps, but you can inherit from another model in a way that it the second model is one to one in embedded with the first. Your DB has two tables, but the view treats them as one. I am unsure if there is actually a link back from the inheretid model, but I think this is what is done with res_user vs res_partner... the user iniherits and actually creates a res_partner.
