  1. POWant to form a "email id" with editable text field for "username" and a constant "domain name"
    text
    copied!<p>I am creating an application having domains and users. Admin can select any domain and create user inside that domain. In the new user creation view i have a email field. Currently i am creating new user by entering the full email id like "sam@exmple.com".I would like to divide the email id so that only the "username(sam)" part is need to be inserted using the text field. The "@domain" part is appended with the username while the form is being submitted.I wish to have a view in which there will be a email section with a text field for username followed by @domain name(populated from database,population is happening). Here is my current view.</p> <pre><code>&lt;%= form_for @user do |f| %&gt; &lt;%= f.hidden_field :domain_id %&gt; &lt;%= f.label :email %&gt; &lt;%= f.text_field(:email, :size =&gt; 20) %&gt; &lt;%= f.submit "Create" %&gt; &lt;% end %&gt; </code></pre> <p>I am not being able to figure out how to do this. Can somebody help, please.</p> <p>At present i am only having a text_field for my email section.So i need to write the full email id.But i wish to have something like this.<br/> [.............]@example.com<br/> In the text_field(i mean the square braces) only username need to be inserted.The domain part is populated from domain table as per selection of domain.How can i prepare the email section of my view so that all the 3 items(username,@,domain name) are concatenated to form a complete email id at the time of submission.</p> <p>{update} Since i didn't want to add one more field to the table "users", i have not added "user_name" and trying to do with "email" only. Here is my view(question related portions only).</p> <pre><code>&lt;%= form_for @user do |f| %&gt; &lt;%= f.label :email %&gt; &lt;%= f.text_field(:email, :size =&gt; 20) %&gt; &lt;%= f.submit "Create" %&gt; &lt;% end %&gt; </code></pre> <p>Controller(question related portions only)</p> <pre><code>class UsersController &lt; ApplicationController def new @domain = Domain.find(params[:id]) @user = @domain.users.build @title = "Add User" end def create @user = User.new(params[:user]) if @user.save flash[:success] = "Welcome!" redirect_to manageDomain2_path(:id =&gt; @user.domain_id) else @title = "Sign up" redirect_to addNewUser_path(:id =&gt; @user.domain_id) end end end </code></pre> <p>Model(question related portion only)</p> <pre><code>class User &lt; ActiveRecord::Base attr_accessor :email before_create :compose_email def compose_email domain = @domain.domain_name self.email = "#{email}@#{domain}" end end </code></pre> <p>When i am trying with something like (for checking only)</p> <pre><code>domain = "example.com" </code></pre> <p>Then the email id is getting saved properly.(like sam@example.com) As i have many domains, i want to build this domain part dynamically.so when i am using </p> <pre><code>domain = @domain.domain_name </code></pre> <p>Im getting error as "undefined method domain_name". I guess this is due to unavailability of the instance domain in my user model. Can you please suggest,where am i doing wrong. Is there any alternative way for this?</p>
