Selecting Range by Database Attribute for Rails Form -

-

is possible select range maximum number option pulled database? have code below gives 1 option. i'd give options 1 through @item.quantity. 

<%= f.select(:quantity_requested, [1..@item.quantity], {}, { class: 'item-quantity form-control' }) %>

all other examples see of hard coded numbers. appreciate understanding why doesn't work.

thanks!

i've never seen ruby's range dynamic numbers. tried doing in irb , didn't work correctly. alternative use (not tested, idea is):

<%= f.select(:quantity_requested, 1.upto(quantity.times).to_a, {}, { class: 'item-quantity form-control' }) %>

edit: tried in irb console , started @ 0 based, you'll want use upto instead of times, see output below: 

a = 100 a.times.to_a => [0, 1, ... 99]  1.upto(a).to_a => [1, 2, 3,.. 99, 100]

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...
