Thank you so much Mr. Sampath. I solved the problem. I forget that i should used the instance of the customer [def create @customer = Customer.find(params[:customer_id]) @project = Customer.projects.create(project_params) end] ..
It should be [def create @customer = Customer.find(params[:customer_id]) @project = @customer.projects.create(project_params) end] .. :D is it okay to you sir if I ask some question if I can't resolve some problem or become my mentor. I want to learn more in rails 4. :) On Mon, Oct 20, 2014 at 10:05 AM, Sampath Munasinghe <sampathni...@gmail.com > wrote: > Use customer has_many: :projects > accepts_nested_attributes_for :projects > > and then make customer view to handle project data or ( if u need above > approach ) add customer id to above _form.html. > > if u need further help, please let me know. :) > > On Sat, Oct 18, 2014 at 11:43 PM, Colin Law <clan...@gmail.com> wrote: > >> On 18 October 2014 15:09, Pepeng Agimat <eebasadr...@gmail.com> wrote: >> > Good day, I'm a beginner in rails I already develop a simple app in >> rails >> > but i want to upgrade the app to be an ajax, I already created the first >> > model customer but in the second model project where customer has many >> > projects and project belongs_to customer, those ajax form modal that i >> copy >> > in a tutorial didn't work.
