hi friends,
I am new to ruby and i need a help from any one of u.
I have got four tables and all i have to get the thing is i
need to take the Id from one table and pass it in to the another table.
Similarly in the descending order, one to two, to three, to four. ie ,
first tables primary key is the second one''s foreign key. second
table,first table primary key is the third tables primary key and so
on.... Now i have to get that functionality in the manner like, in one
form i need to get four labels where in i can provide and store in to
the database.... and on submitting, it will lead us to the listing page,
where in i had maintained drop down list. But the thing is i am getting
all the contents. I have to get only those first table id contents from
four tables , through foreign reference.
In the database also it is not passing that id values in to
the child tables.
def new
@country = Country.new
@state = State.new
@city = City.new
@category = Category.new
end
def create
@country=Country.new(params[:country])
@state=State.new(params[:state])
#@country.states.create(params[:id])
@city=City.new(params[:city])
#@country.cities.create(params[:id])
#@state.cities.create(params[:id])
@category=Category.new(params[:category])
#@country.categories.create(params[:id])
#@state.categories.create(params[:id])
#@city.categories.create(params[:id])
@country.save
@state.save
@city.save
@category.save
redirect_to :action =>''list''
end
def list
end
and the models are
class Country < ActiveRecord::Base
has_many :states
has_many :cities
end
class State < ActiveRecord::Base
belongs_to :country
has_many :cities
end
class City < ActiveRecord::Base
belongs_to :state
belongs_to :country
end
class Category < ActiveRecord::Base
belongs_to :state
belongs_to :country
belongs_to : city
end
and the view files are:
list.rhtml
<align>
<form name="combo">
<h4>Select Country<br><%= select(''name'',
''id'', Country.find_all.collect
{|country| country.name}) %><br>
<h4>Select State<br><%= select(''name'',
''id'', State.find_all.collect
{|state| state.name}) %><br>
<h4>Select City<br><%= select(''name'',
''id'', City.find_all.collect
{|city| city.name}) %><br>
<h4>Select Category<br><%= select(''name'',
''id'',
Category.find_all.collect {|category| category.name}) %><br>
new.rhtml
<%= start_form_tag :action => ''create'' %>
<h4>Country<br><%= text_field ''country'',
''name'' %></br>
<h4>State<br><%= text_field ''state'',
''name'' %></br>
<h4>City<br><%= text_field ''city'',
''name'' %></br>
<h4>Category<br><%= text_field ''category'',
''name'' %></br>
<%= submit_tag "Add" %>
<%= end_form_tag %>

or modifications
