Selecting data in a view and inserting them in Users database - ruby-on-rails

Question

I am reading the contact informations of users from Outlook API, and I would like to add them to my Users database using a submit_tag approach. But it does not work. So far my form on index.html.erb looks like:
<h1>My contacts</h1>
<table class="table">
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Email</th>
</tr>
<%= form_tag import_contacts_path, method: :put do %>
<%= submit_tag "Import Selected contact" %>
<% #contacts.each do |contact| %>
<tr>
<td> <%= check_box_tag "contact_ids[]", 'Select' %></td>
<td><%= contact.given_name %></td>
<td><%= contact.surname %></td>
<td><%= !contact.email_addresses[0].nil? ? contact.email_addresses[0].address : '' %></td>
</tr>
<% end %>
</table>
<%= submit_tag "Import Selected contactact" %>
<% end %>
My ContactController looks like:
class ContactsController < ApplicationController
include AuthHelper
def index
token = get_access_token
if token
# If a token is present in the session, get contacts
callback = Proc.new do |r|
r.headers['Authorization'] = "Bearer #{token}"
end
graph = MicrosoftGraph.new(base_url: 'https://graph.microsoft.com/v1.0',
cached_metadata_file: File.join(MicrosoftGraph::CACHED_METADATA_DIRECTORY, 'metadata_v1.0.xml'),
&callback)
#contacts = graph.me.contacts.order_by('givenName asc')
else
# If no token, redirect to the root url so user
# can sign in.
redirect_to root_url
end
end
def import
User.create(:first_name => #contacts.givenName , :last_name => #contacts.surname, :email => #contacts.email_addresses)
redirect_to imported_path
end
end
I can read my contact information without any problem, but when i try clicking on the button to import a selection of contact, I have the following error:
NoMethodError (undefined method `givenName' for nil:NilClass):
app/controllers/contacts_controller.rb:26:in `import'
My routes look like
resources 'contacts' do
collection do
put :import
end
Does anyone knows if it is actually possible to create such import function ? Because i am trying to read something that is not on a local database actually.

Answer 1

I ended up creating the following function in the controller:
def import_contact(contact)
Contact.create(email: !contact.email_addresses[0].nil? ? contact.email_addresses[0].address : '', first_name: contact.given_name, last_name: contact.surname, user_id: current_user )
return !contact.email_addresses[0].nil? ? contact.email_addresses[0].address : ''
end
and the the view calls the function: <%= import_contact(contact) %>
This way i unfortunately do not select which conctact i want to import. I import all of them, but that is the best i could find now.

You have called #contacts in
def import
User.create(:first_name => #contacts.givenName , :last_name => #contacts.surname, :email => #contacts.email_addresses)
redirect_to imported_path
end
But you have not define #contacts. Since #contacts is nil and you are calling givenName to nil it is giving error. Can you specify #contacts within import method or before filter so that it would be available with in that method.
Hope defining #contacts will fix the issue. If the issue still exist let me know.
Please check the params, in params the value must have come you can use something like
def import
User.create(:first_name => params[:givenName] , :last_name => params[:surname], :email => params[:email_addresses])
redirect_to imported_path
end
Try this one and let me know if there is any issue. Or you can send what params that comes.
