Rails: Check value in an array -


i have model, called line_items. contains price field. when user enters price, can foodio_price or delivery_price. , price field has lot of such values.

i want put check on this. here condition:

all prices in price field should foodio_price or delivery_price. if not, give error , if yes, give whether foodio_price or delivery_price.

can in implementing it?

i did quite dirty not working:

       @line_items.each |i|           if i.price == i.product.foodio_price               @line_items.each |i|                 if i.price == i.product.delivery_price                   render :action => "cart"                 end               end           else               @line_items.each |i|                 if i.price == i.product.foodio_price                   render :action => "cart"                 end               end           end       end

it gives error of many render or redirect calls

the clue's in error message -- can render or redirect once per action.

try adding return straight after each call render.

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
