User_profile belongs_to user.

One approach is to use accepts_nested_attributes -
see
http://guides.rubyonrails.org/v3.2.14/2_3_release_notes.html#nested-object-forms
for example.

Have a look in log/development.log and you will see the parameters you
are posting and check they are ok. Also you can do thinks like
inserting puts statements into your code, so if you insert

puts inspect params[:user_profile]

in the code above it will print the params in the server terminal
window so you can check they are ok.

Thanks Fred,

I had tried. This works, but while saving user_profile field values are
nil except ids.
my create method like this

@user = User.new(user_params)
@user_profile = @user.build_user_profile(params[:user_profile])

Thanks

I found the reason but I can not solve it.
user_profile is unpermitted parameter.

I added

def user_params
params.require(:user).permit(:email, :password,
:user_profile_attributes =>[])
end
in the conroller and

accepts_nested_attributes_for :user_profile

in the model.

still the same problem.

Thanks

You need to add the attributes that are allowed for user_profile.

in fact i want to add all attributes of user_profile. for testing
purpose I added firstname & lastname like this
def user_params
params.require(:user).permit(:email, :password,
:user_profile_attributes => [:firstname, :lastname])
end

but still not working.
user_profile is in unpermitted parameter.

Unpermitted parameters: password_confirmation, user_profile

Thanks,

user_profile is in unpermitted parameter.

There shouldn’t really be any parameters of that name. It’s not clear
what changes you made after I suggested accepts_nested_attributes. In
particular how you call fields_for in the view is very relevant.
