How to iterate over an array with hash that has the position included? Could I remove it? I've never come across this before.
var data = [
{
id: 1,
foo: "hello",
...,
},
{
id: 2,
foo: "world",
...,
}
]
When I POST this data
to my controller, in my console I see the data
params also includes the position (0, 1, 2, etc) so I cant iterate over it properly. The full look would be:
React:
...
$.ajax({
url: '/the-url',
type: 'POST',
data: {'line_items': data, // this would have been this.state.data
...
},
success: function (data, xhr) {
console.log("success")
}.bind(this),
error: function (data) {
console.log("error")
}
});
...
Controller:
...
line_items = params[:line_items]
line_items.map do |l| l.id end # error
...
Console:
0
{"id"=>"1", "foo"=>"hello"},
1
{"id"=>"2", "foo"=>"world"},
Also Rails 5 says map
is depreciated. So what to use?
