Question

I have a posts model that I use to make blog posts on a page of my site. I’d like for the content of the post to be HTML formatted, but am having trouble getting it to actually render in HTML. It only shows up as plain text on the blog page. I am using Rails_Admin if that makes a difference.

posts view:

#blog_page
- @posts_list.each do |post|
    %ul.post
        %li= post.created_at.strftime("%B %d, %Y")
        %li.title= post.title
        %li.author
            = 'By: '
            = post.author
        %li.content= RedCloth.new(post.content).to_html

= paginate @posts_list

post model:

class Post < ActiveRecord::Base
attr_accessible :content, :title, :author
has_many :comments

validates :title, :presence => true
validates :content, :presence => true

end

---

posts controller:

class PostsController < ApplicationController

before_filter :authenticate_user!, :only => [:new, :create]

# GET /posts
def index
    @posts_list = Post.order("created_at DESC").page(params[:page]).per(5)
    render 'blog'
end

# GET /posts/
def show
    @post = Post.find(params[:id])
    render 'show'
end

def new
    if !current_user.admin?
        redirect_to '/blog'
    end
    @post = Post.new
end

# POST /posts
def create
    @post = Post.new(params[:post])
        if current_user.admin?
          respond_to do |format|
            if @post.save
              format.html  { redirect_to('/posts', :notice => 'Post was successfully created.') }
              format.json  { render :json => @post, :status => :created, :location => @post }
        else
          flash[:notice] = 'Error creating post!<br/>'.html_safe
            @post.errors.full_messages.each do |msg|
              flash[:notice] << "<br/>".html_safe
              flash[:notice] << msg
            end
          format.html  { render :action => "new" }
          format.json  { render :json => @post.errors, :status => :unprocessable_entity }
        end
      end
    else
      redirect_to '/blog'
    end
end

end

Your view has to be like this:

#blog_page
- @posts_list.each do |post|
    %ul.post
        %li= post.created_at.strftime("%B %d, %Y")
        %li.title= post.title
        %li.author
            = 'By: '
            = post.author
        %li.content= RedCloth.new(post.content).to_html.html_safe

= paginate @posts_list

You could also create a helper for that:

def post_content( post ) 
  RedCloth.new(post.content).to_html.html_safe
end

And just use it in your view.
