hello
I would appreciate some help with the issue below.
I have in a model a hash with array values, like this
class User< ActiveRecord::Base
LIST = { "Dan" => ["333","abc"] ,
"John" => ["777","qwery"] ,
}
end
class UserController< ApplicationController
active_scaffold :user do |config|
config.label = "Test"
config.columns = [:name, :value]
config.columns[:name].form_ui = :select
config.columns[:name].options = {:options => User::LIST.map}
config.columns[:name].update_column = :value
config.columns[:value].form_ui = :select
end
end
I what that on selection of a name from the User::LIST on :value
field
to be presented with the options from the array
how can I do that?
You can't use :select form_ui in this case, you will have to make a
form
override for value column
so I added
module UserHelper
def value_form_column(record, input_name)
if record.name
select_tag input_name, options_for_select(record.name)
else
select_tag input_name, options_for_select([])
end
end
end
is this correct ?
No, you have to set the same id as AS set usually. If you are using
master
branch you will get an options hash instead of input_name, so it's
easier:
def value_form_column(record, options)
if record.name
select :record, :value, options_for_select(User::LIST[record.name]),
options
....
If you are using rails-2.3 branch, you can use
active_scaffold_input_options to
get the id:
def value_form_column(record, input_name)
column = active_scaffold_config.columns[:value]
id = active_scaffold_input_options(column)[:id]
if record.name
select :record, :value, options_for_select(User::LIST[record.name]),
:name =>
input_name, :id => id
I get the id the same way even if User belongs_to other record?
I'm receiving the same RJS error and I thins I receiving the wrong id
I had a look in the html pages it generates, and the select form
element which I want to update
doesn't exists.
this is because in the controller there is no .form_ui ?!
If you make a form override form_ui is not used, even when you set it.
so I should i do it ?
def value_form_column(record, input_name)
column = active_scaffold_config.columns[:value]
id = active_scaffold_input_options(column)[:id]
select :record, :value, options_for_select(User::LIST[record.name]), :name =>
input_name, :id => id
I'm updating the content of a select which doesn't exists, the id I get above
it doesn't exists
.....
sorry for bottoring with this but the documentation is so light
when .update_column is exexcuted i get
RJS error:
TypeError: Cannot call method 'up' of null
You get that error because cannot get the field to update, because
you are not
using AS id schema.
I searched all the docs but only possible solution is to use
Custom
Association Options, but this means the values should be stored in
the
database
thank you
