Adding a site admin user while creating a site

Rails
1

Hi Gurus,

I wanted to add siteadmin user(basically a user with a certain role)
while
creating the site itself. I hope that i have done all the necessary
stuff
by going through raynb’s railscasts (
http://railscasts.com/episodes/196-nested-model-form-part-1) But could
not
see user fields being displayed in the site creation form… Below are
the
details.

I Have two model users and sites. ( user model was created using devise
then i customized it).

Below are my models:

User model

class User < ActiveRecord::Base
*belongs_to :sites ########### I have added this

  • Include default devise modules. Others available are:

:token_authenticatable, :encryptable, :confirmable, :lockable,

:timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable

Setup accessible (or protected) attributes for your model

attr_accessible :email, :password, :password_confirmation,
:remember_me,
:role, :site_id

end

My site model:

class Site < ActiveRecord::Base
has_many :users, :dependent => :destroy * ########### I have added
this*
accepts_nested_attributes_for :users * ########### I have added this*
end

Here is the change i have done to the new method of
site_controller.rb
**
-----------------

  • *def new
    @site = Site.new
    1.times { @site.users.build } *############ I have added this
  • respond_to do |format|
    format.html # new.html.erb
    format.json { render json: @site }
    end
    end
    -------------------
    **
    *Below is the form to which i have made changes, I have added the bold
    part
    in the below form ( this form is called by views/sites/new.html.erb) *
    **
    -------------------------
    <%= form_for(@site) do |f| %>
    <% if @site.errors.any? %>
<div id="error_explanation">
  <h2>Could not save record due to following errors. Please correct

them and continue


    <% @site.errors.full_messages.each do |msg| %>
  • <%= msg %>

    • <% end %>


<% end %>

<%= f.label :sitename %>
<%= f.text_field :sitename %>
<%= f.label :slogan %>
<%= f.text_field :slogan %>
*

Site Admin Details

<% f.fields_for :users do |account_fields| %> <%= account_fields.label :text_field, "email" %>
<%= account_fields.label :text_field, "password" %>
<%= account_fields.label :text_field, "password_confirmation" %>
   <% end %>

**

  • <%= f.submit %>
<% end %> ** *----------------------------* ** After that i have started the rails server could not see any error, But also could not see the user attributes in the site creation page. I could see only the site attributes. Any Inputs are highly appreciated.

Thanks In Advance,
–S

This should be <%= f.fields_for …

Fred

 <%= account_fields.label :text_field, "email" %></br>

<%= account_fields.label :text_field, “password” %>

<%= account_fields.label :text_field, “password_confirmation” %>

Also that should be :site singular.

HI Gurus,

I could achieve this, I wanted to updated a filed in user table without
taking input from user as asked before.I wanted to set a role to user
without taking input from user.So in registration_controller action of
(devise) I have set resource.role=‘siteadmin’.But its not taking that it
always takes the default value provided for the field.Before integrating
with nested fileds this piece of code to assign role used ot work.but
not
anymore. Is there something extra that i am not doing ?

Thanks,
–S

So This is what it is happennig, the role assign works well if i create
user normally from its own view, But if I create the user form the site
creation view. the role assignment statement (resource.role=“siteadmin”)
doesnt work. This code exisits in the user controller.

Any inputs would be appreciated.

Thanks,
Siva

I think it most unlikely that the assignment statement
(resource.role=“siteadmin”) does not work. I think that after this
statement then resource.role will most definitely be “siteadmin”,
unless you mean that there is an error of some sort when the statement
is run. Presumably what you mean is that later on you find that the
role is no longer “siteadmin”, presumably due to it not being saved or
being overwritten later for example.

What you have to do is to follow the logic flow after that statement
and work out what is going wrong. I suggest you have a look at the
Rails Guide on debugging for some suggestions on how to do this. Look
particularly at how to use ruby-debug to break into your code and
inspect data and follow the flow.

jsut to make little more clear this resource.role=‘siteadmin’ in the
registration_contoller. this registration_controller is devise the
controller generated by devise ( I am using devise for authentication.)

I don’t think that changes the fact that if the code is not behaving
as you expect and you cannot see the problem by examining the code
then you just have to jump in with the debugger and work out what is
going wrong.

Gurus,

Ok, I got chance to rework on it today.As Colin suggested i debugged the
code with the ruby debugger. Below is the details explained.

Controllers:

site_controller.rb

def new

@site=site.new
@site.users.build

end

def create

@site=site.new([:params])
debugger

code i have added

@site.users (using debugger i did p @site.users it prints the
usertable with values i have given in form but role = nil because i dont
take role value in form)
@[email protected]
@test.role=‘admin’ (using debugger i did p @site.users it prints the
usertable with values along with role as admin) But DB is not updated.
##############################

end

registartion_controller.rb

def create
resource=build_resource
resource=‘guestuser’ ( even it wont set user as guest user when i
create a user using hte site form.But when i create user from the user
view it self the user role is set to guestuser.)

end

user.rb

belongs_to: site

attr_accessible: role ( and few others here)

-------------------------
site.rb

has_many: users

So I could not set a role for a user from other contoller sites in
nested attributes. Can somebody help me on how to set a role for user
from the sites table ( in the nested attribute model)

You don’t appear to have saved anything to the database.

Colin,

Thanks for your valuable inputs.

if I do @site.users.role (this throws me an error) but not @test.role
does not

Can you let me know below

  1. how go about adding a role ot user object . coz I have given
    resource.role=‘sitadmin’ in the user controller (which is
    registartion_controller)
  2. I am doing @site.save ( which I thought would save the data to
    database) If i needed to do explicitly can you pls let me know

Sorry Now i got it.

you meant to say read each user object from the @site.users and operate
on them.

thanks a lot :slight_smile:

So you are saying that
@site.users.role = ‘admin’
throws an error, but
@test = @site.users
@test.role = ‘admin’
does not. I find that difficult to understand. Can you check that
again.
The normal way to do it would be to use
@site.users.each.

If you don’t know how to use each then you need to work through some
ruby tutorials. You can’t expect to write rails apps without a good
knowledge of ruby.

Can you let me know below

    resource.role=‘sitadmin’ in the user controller (which is

The create method you posted above did not have save in it. Also
after you change the roles you will have to save the user records as
they have changed.
