Rails Link_To External Site, Url Is Attribute of User Table, Like: @Users.Website

RAILS link_to external site, url is attribute of user table, like: @users.website

Looks like you need to stick the protocol on your link. E.g. you have www.userswebsite.com in your database, it should be http://www.userswebsite.com

Rails: Having a small issue with link_to and external URLs

Prepend url with protocol if it's absent:

module ApplicationHelper
  def url_with_protocol(url)
    /^http/i.match(url) ? url : "http://#{url}"
  end
end

<%= link_to link.title, url_with_protocol(link.url) %>

How do I defined a variable link_to to an external URL

It sounds like you are storing URLs without the http:// so they are being interpreted as relative URLs. You just need to do something like this:

link_to micropost.website, "http://#{micropost.website}"

or maybe add a full_url method to that model that adds it if it's missing.

By the way, you can't use @micropost in that partial because it doesn't exist (you only have @microposts or micropost).

Rails creating links to external sites with %= link_to %

Yes,

http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to

<%= link_to 'facebook', 'https://www.facebook.com' %> 

combine each do |f| with link_to controller action

<% @account.users.each do |f| %> 
     <ul> <h2><%= f.name %> |
              <%= f.email %> |
              <%= f.account_id %> </h2>
              <%= link_to "Remove this user",  user_path(f, :user => { :account_id => 0}),
             :method => :put %> </ul>
<% end %>

@user will be current user and that is why it is updating current user

Preselecting an attribute in a form when creating new model in Rails

You can try passing the params to the new object in your controller, this should auto-populate the form:

def new
  @regiser = Register.new(registered_at: params[:date]) #I don't know the column's name
end

how do add a link to an ActiveAdmin view

You can try:

row :foo do
  link_to('foo','#')
end

and replace '#' with your route.

How do I prevent images loaded from external websites/url's from slowing down my apps page loading times in ruby on rails?

This is because OpenGraph.fetch(url) launches an http request to get the necessary data to find the image tag. Since this has to occur during the render of your action, you can't send any information to the client until they all complete.

While there are many ways to deal with this, I would recommend creating a new action that given an opengraph identifier will return the opengraph data (basically put the helper method into the controller) and only output the identifier into the main action's view html. Then, in javascript, find all of those and execute an AJAX request to get the OpenGraph data and update the page's HTML once you have the response. This will allow the browser to execute the http requests in parallel while also not blocking the render of the page. For bonus points you can cache the OpenGraph responses in memcache or something with a reasonable expiration time and save the latency of having to HTTP request from your app each time.
