ruby - Rails - Serve static CSV file as assets in Development with Thin -


i'm trying write csv file in dev thin, continually getting error says no such file or directory - http://localhost:3000/assets/tplan_log.csv

however, config looks this:

development.rb

config.serve_static_assets = true

and controller looks this:

def csv    #this returns valid path    log_path = view_context.asset_path 'plan_log.csv'     #error occurs here    csv.open(log_path) |csv|      csv << ["row","row1","row2"]    end    respond_to |format|     format.js {render json: @diaggroup.errors, status: :unprocessable_entity}   end end

rails 3.2.12

edit: clarify, i'm looking answer on how serve file in development accessible. know it's being served asset pipeline, there no method associated it, it's not able accessed.

this ended being issue reference.

i using reference such as:

http://path/to/file.jpg

rails wants:

/path/to/file.jpg

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
