ruby on rails - How to fix NoMethodError in #show error? -


i'm trying access specific review through link:

<%= link_to "full review", review_path(review) %><

show.html.erb:

 <%= @review.pro %>

reviews_controller.rb:

def show      @review = review.find(params[:id]) end

i have column in review table named pro shown in migration file here:

class createreviews < activerecord::migration def change   create_table :reviews |t|     t.string :pro     t.string :con     t.string :advice     t.string :date     t.string :role     t.string :company      t.timestamps   end end

end

the error is:

undefined method `pro' nil:nilclass extracted source (around line #1):  1: <%= @review.pro %>

even when include 'puts @review' in show method, nothing gets returned in rails console. advice on how fix this?

update when manually include review.find(1) in show method:

processing reviewscontroller#show html parameters: {"id"=>"1"} rendered reviews/show.html.erb within layouts/application (0.9ms) completed 500 internal server error in 3ms

actionview::template::error (undefined method pro' nil:nilclass): 1: <%= @review.pro %> app/views/reviews/show.html.erb:1:in_app_views_reviews_show_html_erb___648582160945665650_70143359368840'

nil exceptions of hardest debug. have "follow nil" @sameera207 suggesting.

in controller, try

def show    @review = review.find(params[:id])   logger.info "review: #{@review}"   logger.info "review nil? #{@review.nil?}" end

if log/development.log shows review nil?: true you're not finding right record. params should show in log file, too.

Why does Ruby on Rails generate add a blank line to the end of a file? -

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
