Question

I am working on a rails application and I have a Dashboard::user(dashboard/user) controller and I would like for users to update their blog post through the backend of the site. That works fine but when I am trying to get a list of the latest blog post a user has created I get an error.

dashboard/users_controller

def content
  @blog = Blog.new
  render ('content')
end

dashboard/blogs/_blog_list.html.erb

<%= div_for(:dashboard ,blog) do %>
  <%= link_to image_tag(blog.preview.url(:thumb)), dashboard_blog_path(blog) %>
  <h1><%= link_to (blog.title),dashboard_blog_path(blog) %></h1>
   <p><%= truncate blog.excerpt, length: 160 %></p>
  <%= blog.published_at %>
  <%= blog.site_id %>
<% end %>

controller

def content
  @site = Site.find_by_subdomain!(request.subdomain)
  @blogs = @site.blogs.all
  @blog = Blog.new

  render ('content')
end

content.html.erb

<%= render :partial => 'dashboard/blogs/blog_list', :locals => {:blogs => @blog} %>

Any reason why this is not working?

Answer 1

My best guess is that the local variable blog was never set. @blog will be available in the partial, but blog will only be available if it is explicitly set, for example if the partial is rendered via

render :partial => "blogs/blog_list", :locals => {:blog => @blog}
