ruby on rails - Join two tables and select record(table2) to form(table1) with drop-down-select -

-

i join 2 tables have table 'persons' , table 'factories'.

my question is, how can add person , choose (with dropdown) factory person belongs to?

my persons model:

class person < activerecord::base   has_many :factories    has_attached_file :cv    attr_accessible :cv, :email, :function, :mobile, :telephone end

my factories model:

class factory < activerecord::base     belongs_to :persons    attr_accessible :last_name, :email, :telephone, :first_name, :website, :country end

i want example:

| add person |

function: (input field)

telephone: (input field)

mobile: (input field)

email: (input field)

factory (drop-down) <= actual field have , not placed in persons table default.

cv: (upload field)

submit: (submit button)

i hope understand have , hope help.

**edit 1 changed plans. have chosen factory.id in column in persons table.

i made column in person table name factory.id to store data other table in column. possible?**

you can this:

controller:

@people=person.new  @factories = factory.all

view:

    form_for @people |a| . . .     = a.select :factory, options_for_select(@factories.map{ |f| [f.name, f.id] })

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
