Ruby - form save
From Logic Wiki
def create
@article = Article.new(article_params)
if @article.save
flash[:notice] = "Article was successfully created"
redirect_to article_path(@article)
else
render 'new'
end
end
Flash message code added to application.html.erb under app/views/layouts folder (right under <body> and above <%= yield %>:
<% flash.each do |name, msg| %>
<ul>
<li><%= msg %></li>
</ul>
<% end %>
Code added to display errors in the new.html.erb template under app/views/articles folder:
<% if @article.errors.any? %>
<h2>The following errors prevented the article from getting created</h2>
<ul>
<% @article.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
<% end %>
To create the show action, add the following show method to articles_controller.rb file:
def show @article = Article.find(params[:id]) end
To create the show view, add a show.html.erb file under the app/views/articles folder and fill in the code:
<h1>Showing selected article</h1> <p> Title: <%= @article.title %> </p> <p> Description: <%= @article.description %> </p>
