I am generating xlsx files with axlsx_rails gem.
After collecting user input I am posting data to /basic_report_post.xlsx
Controller action looks like
def basic_report_post
@config = params[:config]
@data = params[:data]
@filename = "#{Rails.root}/public/test.xlsx"
respond_to do |format|
format.xlsx {
render xlsx: 'basic_report_post'
}
end
end
View file for this action basic_report_post.xlsx.axlsx
wb = xlsx_package.workbook
wb.add_worksheet(name: 'Data1') do |s|
# Drawing columns
end
xlsx_package.serialize @filename
My problem is that I am getting response data(in post success action) that is raw .xlsx file.
But I need somehow respond @filename
(format json/html) to download it after.
It is possible to use the axlsx_rails
template renderer to create a string and save it to file:
def basic_report_post
@config = params[:config]
@data = params[:data]
@filename = "#{Rails.root}/public/test.xlsx"
File.open(@filename, 'w') do |f|
f.write render_to_string(handlers: [:axlsx], formats: [:xlsx], template: 'path/to/template')
end
render json: {name: @filename}
end
Then you can use the template to serve the file directly if need be.
