A Simple example of Using iframe in Rails

Write the code for iframe and in the src option give the path that defined in routes. It will render the file which corresponding action of the controller renders.

An Haml example is given below:

%iframe{:align => "center", :name => "window", :src => "#{list_make_shipments_path(:ids => "#{@shipment_success_responses.collect(&:id).join(",")}")}", :height => "1000px;", :width => "1100px;", :style => "float:left;margin-top:30px;"}

Create an Image from base64 encrypted image digest data

Suppose you have a base64 digest data of an image, how are you going to display it in your website?

For example You an encrypted image data like this : PCFET0NUWVBFIEhUTUwgUFVCTElDICItLy9JRVRGLy9EVEQgSFR…

Here is an example in haml, how to display the image from this data ( you can make corresponding HTML from this if you are using a Html file)


%img{:alt => "File Icon", :src => "data:image/gif;base64,PCFET0NUWVBFIEhUTUwgUFVCTElDICItLy9JRVRGLy9EVEQgSFR...", :style => "float: left;margin-top:200px;", :id => "my_image_id", :class =>"blahblahblah"}

 

Importing contacts from your email using Rails ‘contacts’ gem

Using ‘contacts’ gem you can import all your contact emails.

Step 1:

In Your Gemfile add,

## For Importing Email Contacts
gem "contacts", :git => "git://github.com/abhilashak/contacts.git"
gem "gdata", :git => "git://github.com/abhilashak/gdata-1.git"

For importing from gmail, we need the gem ‘gdata’.

Do bundle install

you are done.

Step 2:

In your views/import_profile_contact/new.html.erb file,

<%=  text_field_tag "profile_contact[email]", "" %>

<%=  password_field_tag "profile_contact[password]", "" %>

Put one more hidden field tag to know that from which email the user need to import

<%= hidden_field_tag :contact_from, @contact_from %>

the values of @contact_from may be gmail, yahoo mail, hot mail. According to which option user clicks pass the corresponding string.

Step 3:

In your controller get the email and password params

@contact_from = params[:contact_from]

email = params[:profile_contact][:email]
password = params[:profile_contact][:password]

if @contact_from && email && password
  if @contact_from == "gmail"
    @imported_contacts = Contacts.new(:gmail, email, password).contacts
  elsif @contact_from == "yahoo_mail"
    @imported_contacts = Contacts.new(:yahoo, email, password).contacts
  elsif @contact_from == "hotmail"
    @imported_contacts = Contacts.new(:hotmail, email, password).contacts
  end
end

You will get all contacts in an array….

Install Rails 3.1.3 and set up in Linux

Install RVM

If you are not already installed RVM install from here:
https://rvm.beginrescueend.com/rvm/install/

If you already have rvm installed, update it to the latest version.

$ rvm get latest
$ rvm reload
$ rvm -v

Create a Rails 3.1.3 Gemset

Create a default Rails 3.1.3 gemset. It’s advisable to create a new gemset for each application you build. But to get started, create just one new Rails 3.1.3 gemset as your default.

$ rvm ruby-1.9.2-p290@rails313 --create --default

To see a list of the gemsets you have installed:

$ rvm gemset list

And see a list of the gems included with the standard Ruby installation:

$ gem list

$ rvm list gemsets

rvm gemsets

ruby-1.9.2-p290 [ i386 ]
ruby-1.9.2-p290@global [ i386 ]
=> ruby-1.9.2-p290@rails313 [ i386 ]

Make sure you are using the newest version of Rake before you install Rails 3.1.3.

$ gem update rake
$ rake --version

Install Rails

$ gem install rails -v "3.1.3"
