ruby - Sinatra displaying all data to user (custom dictionary and definition app) instead of data for specific word -

trying make user custom dictionary. @ index, user present list of of custom words , have ability add more. can click link specific page on word user shown definitions , can add more.

my problem definitions words displayed.

below ruby code..

        class word       @@words = []       define_method(:initialize) |word|         @word = word         @id = @@words.length().+(1)         @definitions = []       end       define_singleton_method(:all)         @@words       end       define_method(:save)         @@words.push(self)       end       define_singleton_method(:clear)         @@words = []       end       define_method(:id)         @id       end       define_singleton_method(:find) |ident|         found_word = nil         @@words.each() |word|           if word.id.eql?(ident)             found_word = word           end         end         found_word       end       define_method(:add_definition) |definition|         @definitions.push(definition)       end       define_method(:definitions)         @definitions       end       define_method(:word)         @word       end     end         class definition       @@definitions = []       define_method(:initialize) |definition, part|         @definition = definition         @part = part         @id = @@definitions.length().+(1)       end       define_singleton_method(:all)         @@definitions       end       define_method(:save)         @@definitions.push(self)       end       define_singleton_method(:clear)         @@definitions = []       end       define_method(:id)         @id       end       define_singleton_method(:find) |ident|         found_definition = nil         @@definitions.each() |definition|           if definition.id.eql?(ident)             found_definition = definition           end         end         found_definition       end       define_method(:part)         @part       end       define_method(:definition)         @definition       end     end 

here sinatra page..

    require('sinatra')     require('sinatra/reloader')     also_reload('lib/**/*.rb')     require('./lib/definition')     require('./lib/word')      get('/')       @words = word.all()       erb(:index)     end      post('/')       word = params.fetch('word_input')       new_word = word.new(word)       new_word.save()       @words = word.all()       erb(:index)     end      get('/word/:id')       @words = word.all()       @definitions = definition.all       @definition = definition.find(params.fetch('id').to_i())       erb(:word_page)     end      post('/word/:id')       definition = params.fetch('definition_input')       part = params.fetch('part_input')       new_definition = definition.new(definition, part)       new_definition.save       erb(:success)     end 

here page displaying definitions words

    <h1>your defnitions word.</h1>     <p>here can view definitions word , add more</p>      <% @definitions.each() |definition| %>     <ul>       <li><strong>part:</strong> <%= definition.part() %>         <br>         <strong>definition:</strong> <%= definition.definition()%></li>     </ul>      <% end %>      <form action="/word/:id" method="post">       <label for="definition_input">new definition</label>       <input id="definition_input" name="definition_input" type='text'>        <br>        <label for="part">new part (e.g. verb, subj, noun)</label>       <input id='part_input' name="part_input" type="text">       <br>       <button type="submit">add defintion , part</button>     </form>      <a href="/">return home page</a> 

first of think should clean code since make lot easier (and in case ask question again people reading question).

see can turn piece of code

define_singleton_method(:find) |ident|     found_definition = nil     @@definitions.each() |definition|       if definition.id.eql?(ident)         found_definition = definition       end     end     found_definition end 

into this

def self.find(ident)     @@definitions.each |definition|         if definition.id == ident             return definition         end     end     nil end 

not beautiful either, transform this:

def self.find(ident)     @@definitions.find{|definition| definition.id == ident} end 

now doesn't answer question though, think coding style important, wanted point out nevertheless.

the problem have inside of view calling

@definitions.each() |definition|

you reference @definitions filled call in sinatra server, need reference @definition , embed view since don't want display definitions. (you might want create second view this).
