Hi,

I have view page which takes all the information like contact’s emails ,  
phones no’s etc and saves different tables. I want to save more than one  
email id’s for a particular contact.

view page is something like this…

.  
.  
Email 1 :  
\<%= select ‘email’, ‘email\_type’, %w(Business Personal), :include\_blank  
=\> false %\>  
\<%= text\_field ‘email’,‘email’,:size=\>“35”,:maxlength=\>“80” %\>  
\<%= radio\_button ‘email’, ‘isprimary’, ‘1’ %\>Primary  
Email 2 :  
\<%= select ‘email’, ‘email\_type’, %w(Business Personal), :include\_blank  
=\> false %\>  
\<%= text\_field ‘email’,‘email’,:size=\>“35”,:maxlength=\>“80” %\>  
\<%= radio\_button ‘email’, ‘isprimary’, ‘1’ %\>Primary  
.  
.

Controller is :

def create  
@contact = Contact.new(params[:contact])  
@contact.emails \<\< Email.new(params[:email])  
@contact.phones \<\< Phone.new(params[:phone])  
@contact.addresses \<\< Address.new(params[:address])  
puts “hellooooooo bharati”  
params.inspect  
if @contact.save  
flash[:notice] = “Contact was successfully created.”  
redirect\_to :action =\> ‘list’  
else  
render :action =\> ‘new’  
flash[:notice] = “Contact was not created.”  
end  
end

Can any one help me how to send more than one email ids to controller…

There’s two separate problems here:

- how you manage the ui, ie adding extra textfields to the page
- how you convince rails to treat these textfields as an array.

The key to the second part is how you name the parameters. In  
particular parameters ending with a [] are treated as arrays.

Yes . I was able to submit more than one text field values… but now my  
issue is how do i differentiate radio buttons with the same name… both  
the radio buttons are getting selected :(… here is the code

\<% form\_for :@contact do |f| %\>  
\<% @contact.emails.each\_with\_index do |email, index| %\>  
\<% fields\_for “email[#{index}]”, email do |f| %\>   
Email &nbsp &nbsp;  
\<%= f.select :email\_type, %w(Business Personal),  
:include\_blank =\> false %\>  
\<%= f.text\_field :email %\>  
\<%= f.radio\_button :isprimary ,‘index’ %\>Primary  
  
\<% end %\>  
\<% end %\>  
\<% end %\>

the builders yielded by form\_for and fields\_for have the same name, so  
they’ll be overwriting each other (which isn’t what I thing you want).  
Also shouldn’t the second parameter to radio\_button be index and not  
‘index’ ?

From the code I’d guess that you end up with params[:email]  
containing the string 1, which you then try and call values on.

ya. got it. But there exists an issues… When i select radio button i ll  
get the following error. . “undefined method `values’ for “1”:String”  
where as the other values get saved if i do not select radio button.

Also If i enter only one email id the form is not getting saved.  
Controller is as follows.

def new  
@contact = Contact.new  
2.times { @contact.emails.build }  
end  
def create  
@contact = Contact.new(params[:contact])  
params[:email].each\_value do |email|  
@contact.emails.build(email) unless email.values.all?(&:blank?)  
end  
if @contact.save  
flash[:notice] = “Successfully created new Contact.!!!”  
redirect\_to :action =\> ‘list’  
else  
render :action =\> ‘new’  
end  
end

Where i went wrong?
