i have 2 models class User \< ActiveRecord::Base &nbsp;&nbsp;has\_many :notes, :dependent =\> :destroy &nbsp;&nbsp;accepts\_nested\_attributes\_for :notes &nbsp;&nbsp;devise :database\_authenticatable, :registerable, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:recoverable, :rememberable, :trackable, :validatable

end

class Note \< ActiveRecord::Base &nbsp;&nbsp;belongs\_to :user &nbsp;&nbsp;validates :content, presence: true,length: { minimum: 15 }

end

the database schema

create\_table "notes", primary\_key: "note\_id", force: true do |t| &nbsp;&nbsp;&nbsp;&nbsp;t.text "content" &nbsp;&nbsp;&nbsp;&nbsp;t.integer "user\_id" &nbsp;&nbsp;end

create\_table "users", primary\_key: "user\_id", force: true do |t| &nbsp;&nbsp;&nbsp;&nbsp;t.string "first\_name" &nbsp;&nbsp;&nbsp;&nbsp;t.string "last\_name" &nbsp;&nbsp;&nbsp;&nbsp;t.string "email", default: "", null: false &nbsp;&nbsp;&nbsp;&nbsp;t.string "encrypted\_password", default: "", null: false &nbsp;&nbsp;&nbsp;&nbsp;t.string "reset\_password\_token" &nbsp;&nbsp;&nbsp;&nbsp;t.datetime "reset\_password\_sent\_at" &nbsp;&nbsp;&nbsp;&nbsp;t.datetime "remember\_created\_at" &nbsp;&nbsp;&nbsp;&nbsp;t.integer "sign\_in\_count", default: 0, null: false &nbsp;&nbsp;&nbsp;&nbsp;t.datetime "current\_sign\_in\_at" &nbsp;&nbsp;&nbsp;&nbsp;t.datetime "last\_sign\_in\_at" &nbsp;&nbsp;&nbsp;&nbsp;t.string "current\_sign\_in\_ip" &nbsp;&nbsp;&nbsp;&nbsp;t.string "last\_sign\_in\_ip" &nbsp;&nbsp;&nbsp;&nbsp;t.datetime "created\_at" &nbsp;&nbsp;&nbsp;&nbsp;t.datetime "updated\_at" &nbsp;&nbsp;&nbsp;&nbsp;t.boolean "admin", default: false &nbsp;&nbsp;end

this is my method for saving notes def save\_note &nbsp;&nbsp;&nbsp;&nbsp;@note = Note.new(lesson\_params)

&nbsp;&nbsp;&nbsp;&nbsp;if @note.save &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;flash[:notice] = "You have successfully add a lesson." &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;redirect\_to pages\_home\_url &nbsp;&nbsp;&nbsp;&nbsp;else &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;flash[:notice] = "Failed." &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;redirect\_to pages\_home\_url &nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;end

&nbsp;&nbsp;private

&nbsp;&nbsp;def lesson\_params &nbsp;&nbsp;&nbsp;&nbsp;params.require(:note).permit( &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:content) &nbsp;&nbsp;end end

when i save a note isn't put in my database the user\_id and I don't know why...I have to extract the curent user\_id and i don't preaty much kknow how to do it. Also, i check in console and this i get :" INSERT INTO `notes` (`content`) VALUES ('asdasd asdakshdasmd ')". It seems like my user\_id isn't inserted in db. i came from another world called php and there the things are different.

If you update this:

@note = Note.new(lesson\_params)

to:

@note = current\_user.notes.new(lesson\_params)

that should work the way you want.

I must be honest- I am running into this problem myself learning rails. I thought that when I create something the user\_id should be generated automatically in the created model. While testing I figured I would come back to it. In the meantime I set user\_id in my entry table manually in the create method ( I am using devise): @entry = Entry.new(entry\_params) @entry.user\_id=current\_user[:id]

I assume the above code is in a CONTROLLER. If so, you should stick to the controller actions **index, new, create, edit, update, and show**. Avoid creating a controller action with another name.

You didn’t show us the VIEW. In the VIEW, does the form you are submitting contain a user\_id ? If not, that is why you don’t have a user\_id in your notes record.

If this note is supposed to be associated to the currently logged in user, you’ll want to add

before\_filter authenticate\_user!

to the top of your controller, and also in your create method do something like this:

current\_user.notes.create(lesson\_params)

You will find this documented in the section marked “has\_many Association Reference” on this page:

[http://guides.rubyonrails.org/association\_basics.html#has-many-association-reference](http://guides.rubyonrails.org/association_basics.html#has-many-association-reference)

(By the way, the current\_user method itself comes from devise, which documentation you should thoroughly read here: [https://github.com/plataformatec/devise](https://github.com/plataformatec/devise))

Finally, get yourself RubyMine and learn how to use the Go-To-Declaration (Command-B). Do that NOW before you go any further. (Another IDE is acceptable too if it has Go-To-Declaration functionality)

Why are you not using the default primary key (id)? You will just make life difficult if you avoid the rails conventions unless you have a good reason for so doing.
