Question: I'm a noob self learning programmer and i'm wondering how can i make an application for mobile. As an example, so you can understand what i need (and easier for me to explain), think of an application where the user can store products and related information by filling forms (an icon, price, name, features, weight...) and then consult stored information.

For me it looks like the best way to create it is by using web related tools like HTML, CSS, MySQL...

The problem i find is that i don't know how to create a web shaped application and then turn it into a mobile app. 

I'm sorry if i didn't explain the best way, but hope you guys get my point are able to put me in the right way!

Thanks a lot in advance!!

P.S. Beyond HTML and CSS and a little MySQL i have basic knowledge of JS, C++ and C#.

Answer: 
It seems that by putting resources\_attributes into a string is enabling me to get the right params in the consol. 

```
  simple_fields_for "resources_attributes" do |e| 

```

I don't know if it is good practice but it works fine.
Can you try the following change?

Replace

```
<%= f.simple_fields_for :resources do |e| %>

```

with

```
<%= f.simple_fields_for :resources_attributes do |e| %>

```
