hi trying use rails on rest 2 - movielist tutorial rails 4 , making adjustments go new rails. stuck on associations of movies roles. have added movie.rb class movie < activerecord::base has_many :roles, :dependent => :destroy has_many :people, :through => :roles validates_presence_of :title def new_role=(values) values.each |i, hash| unless hash[:name].blank? roles.create(:person_id => hash[:person_id], :name => hash[:name]) roles.save end end end def deleted_roles=(values) values.each |role_id| roles.find(role_id).destroy end end end and show _form.html.rb render (excert below) <b>add new people</b><br /> <% (1..3).each |i| %> <%= select_tag 'movie_new_role_person_id', options_for_select(@people), { :name => "movie[new_role][#{i}][person_id]" } %> <%= text_field_tag 'movie_new_role_name', '', { ...

i'm trying products within 1 category, want search categoryid. want list filled products categoryid example 3. how can this, i'm using nopcommerce 3.10. someone on nop forum achieved using following line: _productservice.searchproductvariants(categoryid, 0, string.empty, false, 0, int.maxvalue, false); but since use 3.10 , productvariants replaced products, can't use this. thanks in advance! i figured out myself: for products within 1 categoryid: nopengine _engine; /// <summary> /// returns ipagedlist(product) filled products selected categoryid /// </summary> /// <param name="categoryid"></param> /// <returns></returns> public ipagedlist<product> getallproductsfromcategory(int categoryid) { _engine = new nopengine(); var _productservice = _engine.resolve<iproductservice>(); list<int> c...

i'd populate existing list unordered list has 10+ li's. i'd populate js or jquery html file containing li's or i'd populate ul li's commented html. <div class="lcatnav categorynavigation"> function write_list_item(){ var items = document.getelemntbyid("lcatnav categorynavigation"); is possible? so far i'm trying append ul using function element id (the ul) append said ul bunch of variables. isn't working well! using html dom can list name using document.getelementbyid("mylist"); you can set variable equal element or work directly using appendchild() method. document.getelementbyid("mylist").appendchild(newlistitem); or var list = document.getelementbyid("mylist"); (var = 0; < elements.length; i++) list.appendchild(elements[i]);

after long search found winning strategy clean code on hangman game, explanation needed understand. when game opens, wanted letter buttons disabled. created method that, private void disableletters(); { a.enabled = false; b.enabled = false; . . . z.enabled = false; } effective not elegant. iterating through alphabet try , condense code seemed logical. private void disableletters() { char alphebetstart = char.parse("a"); char alphabetend = char.parse("z"); (i = alphabetstart; <= alphabetend; i++); { string allletters = i.tostring(); } } but challenge appeared starting because couldn't use these newly created strings button forms this, i.tostring().enabled = false; for obvious reasons. strings needed understood original form. the long search revealed solution, don't understand quite it's doing. magic was, controls[allletters].enabled = false; the "controls" reveals cryptic...

we want use code contracts on our interfaces. have large interface hierarchy, leading awful lot of duplication in contract classes. we have interface ix (through inheriting other interfaces) has around 50 methods. there several interfaces derive ix . interface iy inherits ix , adding couple of methods. if want add contract class iy , need reference 50+ methods. worse, if later on decide modify ix , have change contract classes interfaces inheriting ix . discourages developers making changes. is there way of avoiding duplication? i don't believe possible, no. can't derive 1 interface contract class another, , interface contracts classes can't have base class other system.object. think you're stuck. best way forwards involve kind of code generation tool, or lots of copy-and-pasting.

im using minimagick resize images on server. having issues forcing dimensions on it. minimagick git documentation states uses mogrify commands. looking further, there sever commands can use in resize such as: -resize "230x200>" -resize "230x200<" -resize "230x200!" i looking use ! seems not working. img = sftp.download!("local_promos/#{@image_name}") ri = minimagick::image.read(img) ri.resize "230x200!" # ! ignored , not resize ri.write('#{img_dir}#{@image_name}') i ran mogrify command in command , worked fine. seems issue? the problem gem mini_magic. using -v 3.5.0. escaping string using shellwords.escape(value.to_s) newer version 3.6.0 fixed issue.
