How can i add values for a field from another model in rails?

问题

I have a user model and language model where the language model contains list of languages and the user model contains the information of the user. In user model there is a field called language where the user should select a language from the language model. And for all these i do not have form and i want to pass the id of the language when creating new user and it should save the language for the user. I use curl to create and update.

So please tell me how i can do this? Please help me.

Thanks in advance.

I think nested attribute is what you need. You can learn more about it here : Active Record Nested Attributes

Additionally for simulating nested attribute calls using curl, you can look at this post :
