Ruby-on-rails – mongomapper, rails3 edge: undefined method `to_key’ on form_for

devisemongomapperruby-on-railsruby-on-rails-3

when i am trying to get the basic devise examples running with current git versions from rails, mongomapper and devise, i have the following error appearing:

undefined method `to_key' for #<Admin:0x23dee04>

here is my actual source:

4: = form_for @admin, :url => admins_path do |f| 
5:   - field_set_tag 'Update my email' do 
6:     %p= f.text_field :email 
7:     %p= error_message_on @admin, :email

@admin is the currently logged in user (@admin= current_admin)
the same error occurs when trying to use @admin=Admin.first in the
controller

i am not quite sure if this is a mongomapper problem, might also be
rails3 related…
thanks for any pointers…

the same happens if i am using the erb equivalent, see

<%= form_for @admin, :url => { :action => "create" } do |fr| %>
<%= fr.text_field :sign_in_count %> 
<% end %>

here is the full error output: http://pastie.org/871850

I have submitted a patch to MongoMapper here:

Ruby-on-rails – devise and multiple “user” models

Welcome aboard Java guy =), I hope you'll enjoy the Rails world. Simply, to solve your issue you have 2 solutions:

For each user create a table in the database and corresponding model.
Create a single table in the database and for each user type create a model. This is called single table inheritance (STI).

Which one to choose? It depends on the common attributes of the roles. If they are almost common (for example all have a name, email, mobile, ...) and a few attributes are different, I highly recommend the STI solution.

How to do the STI? 1. Simply create the the devise user model and table using the command rails generate devise User 2. Add a column named type with string datatype to the user table in the database using a migration. 3. For each user type create a model (for example rails g model admin) 4. Make the Admin class inherits from user model

class Admin < User
end

That's it you are done =) ... Yupeee

To create an admin run the command Admin.create(...) where the dots is the admin attributes for example the email, name, ...

Ruby-on-rails – undefined local variable or method `current_user’

From your routes file, the helper should be

current_t_buser

From the documentation of devise

Notice that if your devise model is not called "user" but "member", then the helpers you should use are:

before_filter :authenticate_member!

member_signed_in?

current_member

member_session
