model/blog.rb

class blog < activerecord::base   attr_accessible :body, :name   validates :name, :presence => true, :length => {:in => 3..10}   belongs_to :user end 

please check codes , let me know did mistake , kindly me make blog application correctly according story explained above.

this not forum post random code , have else fix it. please make sure read guide on how ask question: https://stackoverflow.com/help/how-to-ask

as next step please make sure read , understand error messages, because best thing solve problems yourself.

next i'd point blog post explaining how debug rails application yourself: http://nofail.de/2013/10/debugging-rails-applications-in-development/

it's important understand rails error-message trying tell you:

undefined method name array:0x21896a0

so it's calling .name on array.

showing c:/site/library_management1/app/views/homes/blog.html.erb line #19 raised:

it's doing in blog.html.erb on line 19 suppose part here:

 <%= form_for :blogs,:url => {:action => 'savecomments',:id => current_user.id } |f| %>  <p>   <label for="name">name:</label>   <%= f.text_field :name,placeholder:"enter name" %> </p> 

so form trying call .name on nested object defined :blogs in order :name property f.text_field. object form trying work with?

nomethoderror in homes#blog

looking @ controller code of homes#blog see possible form object comes from:

def blog     if params[:id]         @blogs=blog.find(params[:id])         @blogs=blog.all     else     @blogs=blog.new     end end 

so thing array @blogs = blog.all. , code not makes sense me. why doing blog.find replace blog.all in next line?
