ruby on rails - How to send params from nested forms? -


i'm making post request nested form written in reactjs such making ajax request create method of products controller.

react code:

i have empty object in getinitialstate this

getinitialstate: function() {  return {    products: [{name: '', price: '', quantity: ''}],    count: 1  }; },

when submit form,

handlesubmit: function(e) {   e.preventdefault();   var productsarray = this.state.products;   $.ajax({     data: {       product: productsarray     },     url: '',     type: "post",     datatype: "json",     success: function ( data ) {       console.log(data);       // this.setstate({ comments: data });     }.bind(this)   }); },

the object gets populated , parameter hash becomes 

parameters: {"product"=>{"0"=>{"name"=>"", "price"=>"", "quantity"=>""}}, "shop_id"=>"gulshop"}

so i'm getting 

activerecord::unknownattributeerror (unknown attribute '0' product.):

how can parameter hash this:

parameters: {"product"=>[{"name"=>"", "price"=>"", "quantity"=>""}], "shop_id"=>"gulshop"}

what can done ?

your original error 'unknown attribute '0' product.' because product class not have attribute '0'. i'm not sure '0' coming haven't posted react code makes request.

you can make request component using jquery's .ajax method. e.g

$.ajax({   type: 'post',   url: '/your_url',   data: {     course: {       name: 'hello world',       price: 120     }   } });

you have following in controller..

class productcontroller < applicationcontroller   def create     @product = product.create(product_params)   end    private    def product_params     params.require(:product).permit(:name, :price)   end end

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
