ok i'm trying deploy first rails project. i've asked this question , think figured out can't configure apache work using ip , have have domain name. the reason can't use domain name yet because i'm recreating site , don't want down in between switching domain current site new rails site. i'd rails app running on server can test out , once it's ready, switch domain name. how can setup server run rails project without using domain name? if want run rails project locally in development mode, run command rails s root of project. it possible deploy 2 apps same server, or 2 versions of same app, typically use sub-domains this, website.com , testing.website.com. you need have seperate databases , seperate virtualhost files. you try access apache machine it's ip address if on local network.

i'm working on swing app allow users view sets of (mostly locally-stored) files. i'm able store lists of files (among other preferences) text in properties files when try pull file values out, using myproperties.getproperty("file") it discards some of '\'s in text. confirmed writing properties files this: myprintwriter.println("file = " + myfile.tostring().replaceall("\\\\", "/")) or this: myprintwriter.println("file = " + myfile.tostring().replaceall("\\\\", "\\\\\\\\")) would allow getproperty() work more expected didn't having convert data java-specific format without explanation in api decided write on stack overflow. but when got point in post started feeling embarrassed; post on stack overflow without consulting java source code java.util.properties (distributed jdk). found javadoc comments properties.load() indicate design decision which, example, allows properties v...

i use backbone-relational's includeinjson: 'id' include related model ids avoid spamming server-side whole object tree. unfortunately, backbone.marionette.view default exposes attributes of view mode returned tojson, means related models no longer accessible in view templates. i realize need custom marionette.view serializedata. needed models, i'm hoping solve generically; i.e. override serializedata views such right thing backbone-relational id references. any chance someone's done this? i'm not hopeful of that, figure there others use this, if nothing else serve place dump solution once i've coded it. :) any solution require 1 of these options: define 2 versions of tojson models, 1 uses includeinjson , other treats true. some way punch hole through marionette's restriction on view templates using model attributes , attribute-based helpers. i've got functional solution using option #1, it's such hack can't bear post p...

how can httpservletrequest parameter (especially in jsp) unset or removed (like in php using unset($_post['index']) function)? have tried following. map requestmap=request.getparametermap(); requestmap.remove("index"); but says no modifications allowed locked parametermap is there way unset request parameters? is there way unset request parameters? afaik, not within jsp (or servlet matter). but write filter wrapped current request in way replaces parameter map.

recently got test binary. when checked using objdump, observed includes hard coded library path. why needed to hardcode path that? shouldn't path taken shell environment variables or -l parameter instead ? objdump -p testprog the output includes hardcoded path shared libraries: .... needed /home/test/lib/liba.so needed /home/test/lib/libb.so needed /home/test/lib/libc.so .... this because 3 .so files had no soname on host test program built. tell person built rebuild liba.so -wl,soname,liba.so , similar other two, relink main program.

say have www.foo.com domain setup load app on foo.appspot.com how set things site can accessed sub-domain (such user.foo.com )? , how understand in app request has sub-domain value of user ? i'm not sure modifications need make in dns, , modifications need make in code read subdomain. maybe there's easier way, user.foo.com requests load (not redirect) foo.appspot.com/user , in case straightforward handle in code. i'm not sure how make these modifications - i'm trying achieve each of users gets own subdomain. you need wildcard cname, there info in app engine docs , if recall correctly not dns providers support that. also can't (without redirect) map {user}.domain.com www.domain.com/{user}.

is there way count letters of inner text of html element, without counting letters of inner element's texts? i tried out ".gettext()" method of "webelements" using selenium library, counts inner texts of inner web elements in (e.g. "<body><div>test</div></body>" results in 4 letters "div" and "body" element, instead of 0 "body" element) do have use additional html parsing library, , when yes 1 recommend? i'm using java 7... based on this answer similar question , cooked solution: the piece of javascript takes element, iterates on child nodes , if they're text nodes, reads them , returns them concatenated: var element = arguments[0]; var text = ''; (var = 0; < element.childnodes.length; i++) if (element.childnodes[i].nodetype === node.text_node) { text += element.childnodes[i].textcontent; } return text; i saved script script.js file , lo...

well googled question couldn't find or it's not correct question.. the issue need modify primary_key name of database :id :another_id, in project need use pgrouting , contains several plsql functions , these functions uses primary-key name gid , instead of modify plsql functions better change id name, , thinking migration becouse thought it's rails way. is possible, , how can ?? thanks in advance , sorry english. edit create_table :pruebas, primary_key: :gid |t| t.string :name t.timestamps end this trick, , active record generate , uses pk gid. sorry if question not clear.. gracias por las respuestas. to set primary key yourself, when create table, do: create_table(:table_name, primary_key: 'gid') |t| ... end and need define primary key name in model: self.primary_key = 'gid'

i'm planning project using atmega (i can't use arduino directly because of university's restrictions). want use arduino's ide, serial monitor, plotting graphs using processing debugging purposes. can dump regular atmega code arduino , use serial monitor debugging purposes? can use arduino uno board other normal avr development board can best of both worlds. googled it, didn't answer need. if mean using arduino's avr microcontroller without arduino libraries: that's possible. you're going have mess lower-level stuff, though. can inspiration have done far libavrutil .

this question may toad specific. have no idea how oracle stores views, i'll explain happens when use toad. if answer oracle specific, better. i have created rather complex view. make clearer, have formatted code nicely, , entered comments needed. when need make changes view, use toad's "describe objects" window, can find script recreate view. problem formatting gone. comments before select keyword (but after "create view xxx as") disappear. if enter script create view: create or replace view testviewformatting -- here have long comment explaining role of -- view , things aware of if changing it. -- unfortunately comment disappear... select name, --this comment kept accountnumber --this debtable name 's%'; toad display when describe later: drop view xxx.testviewformatting; /* formatted on 04.07.2012 09:35:45 (qp5 v5.185.11230.41888) */ create or replace force view xxx.testviewformatting ( name, accountnumber )...

here example of problem. i have 'room' model: class room < activerecord::base has_many :items, :inverse_of => :room accepts_nested_attributes_for :items end and have 'item' model: class item < activerecord::base belongs_to :room, :inverse_of => :items validates :some_attr, :uniqueness => { :scope => :room} end i want validate uniqueness of :some_attr attribute of items belongs room. when try validate items, error: typeerror (cannot visit room) i cannot set scope of validation :room_id since items not saved yet id nil. want prevent using custom validators in 'room' model. is there clean way in rails? wonder if set :inverse_of option correctly... i don't see wrong how you're using inverse_of . as problem, in similar situation ended forcing uniqueness constraint in migration, so add_index :items, [ :room_id, :some_attr ], :unique => true this in addition ar-level validation validates_un...
