ruby on rails - Unable to read file from within rake task -

-

i have rake task reads file.

desc "dump images." task :dump_with_images => :environment   yaml_path = rails.root + 'db/data.yml'    # output: "" -- empty string   puts file.open(yaml_path).read.inspect   [...] end end

if read , inspect file outside of task,

yaml_path = rails.root + 'db/data.yml' puts file.open(yaml_path).read.inspect  desc "dump images." task :dump_with_images => :environment

it gives me data:

zeromodulus@kosuna:~/projects/recipes$ rake dump_with_images "\n---\nphotos:\n  columns:\n  - id\n  - created_at\n  - updated_at\n  - recipe_id\n  - image_file_name\

i don't understand why can read exact same file outside of task, not in task.

when inspect yaml_path, they're both same, , file has data in it.

it looks opening file stream , not closing it, , later on in code attempting open same file stream again.

i've wrapped file reading code in block,

file.read(file_path, "r") |f|   yaml.load_stream(f) end

which has solved problem.

update:

the problem has resurfaced, though have opened/closed file streams properly. problem lies elsewhere, couldn't figure out, decided abandoned yaml_db , use standard db/seeds.rb

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
