ruby - Rails: Save country_select to database -

i’m working on form user can pick country , there choice shown , show.html.erb.

i have added country_select in form this

<div class="col-md-4">   <div class="form-group">     <%= f.country_select :country %>  </div> 

my model article.rb looks this:

class article < activerecord::base     belongs_to :author     has_many :article_article_categories     has_many :categories, through: :article_article_categories      validates :title, presence: true, length: { minimum: 3, maximum: 50 }     validates :description, presence: true, length: { minimum: 10, maximum: 500 }     validates :author_id, presence: true      attr_accessor :country end 

the select works , user can select country.. perfect!

but won’t show in view/show.html.erb.. have tried this:

<%= @article.country %> 

so therefor generated migration:

class addcountrytoarticles < activerecord::migration[5.0]   def change     add_column :article, :country, :string   end end 

and ran migration.

in controller added params:

def article_params   params.require(:article).permit(:country, :title, :description, article_article_categories_ids: []) end 

but nothing.. @ country_select documentation, under usage: "simple use supplying model , attribute parameters: country_select("user", "country")"

but don’t know, put line of code.. have tried put in create, show, , params.. , updated (“article”, "country")

can me step closer? devise installed.. maybe cause trouble? i'm working rails 5.0.0

first, rid of attr_accessor :country attr_accessor used define attribute object of model not mapped column in database.

to answer question "but don’t know, put line of code.. have tried put in create, show, , params.. "

you have put line of code in form view. first attribute name of model (article in case) , second name of attribute (country in case). have done with:

<%= f.country_select :country %>

you have make sure form article should be:

<%= form_for @article |f| %>   <div>   <%= f.country_select :country %>   </div> <% end %>
