Re: [Rails] Ajax bootstrap modal in rails 4.. Newbie here!

Ruby on Rails Monday, October 20, 2014

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. :)

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. :)

I guess that params[:customer_id] is null.  Check in development.log
and you will see what parameters are being posted.
