How To Delete One2many Lines From Code in Odoo12

Excellent tutorials, thanks to you I am advanced in my wisp system project, my query is I have a client model and installation the relationship between user and installation is one2many, where each client can have several installations but these installations can only belong to that client ( they have a unique relationship) and it is created at the time of selecting the installation model, could you give me some guide or reference to be able to make this relationship, with your guide I can make the relationship when I add the installation to the client, you also see the other installations that They belong to the other clients and I am not able to do what I want. I would appreciate any guidance you could give me. I would really appreciate it.

why don't you add a delete icon beside each record so that when click on that icon single record can be deleted

thanks odoo mates

It's good to confirm user action, you can add an attribute:
confirm="Do you really want to delete all the lines?"

Thanks a lot brother..
