Hi Chris,

Any plan in near future (couple months) for uploading series about real RoR development ?
I mean like building a commerce site, it would be more complex with real world hurdle ? (AirBnB clone, Amazon clone, Spotify clone; airbnb & amazon we can utilize faker, Spotify provide api service which we can really use)

All these episode is good and all but mostly it is showing us how to use gem (video version of the readme / documentation of the gem).

Hi Liz,

thanks for responding...

With your solution there's might be a performance issue when the products is in thousands of records..

Is it possible that this is where the front-end framework come to play and close the missing link ?

Hi there,

this is very basic thing but How do I populate controls in my form with data from database ?

For example let say I want to create a Invoice / Order of items from my product list.
I must enable user to search the product from a dropdown. how do I populate these dropdown with my product list ?

I know that I can query all the the product and put it in a class variable which will be used in the view with ERB to populate the dropdown, but this might be okay when you have small set of product list or just a couple of dropdown. If I'm to use ajax which how to connect the request from the specific control to rails so it returns the data appropriate with each control (e.g: product list instead of supplier list) ?

I hope I make my question clear.

Why touch the controller files instead 'rails g controller forum_threads' ?
which would save as some trouble with creating the view files also...
