  • has_many :through name suggestions

    - by user1084769
    I have three models, user, achievement, badge and I plan on using has_many :through instead of has_many_and_belongs_to since I will have a few extra fields in the join tables. According to a Railscast I watched, using this method requires coming up with new model names and not user_badge or user_achievement. For my User Achievement join what do you think of Accomplishment? For my User Badge join what do you think of Distinction?

  • Not Equal two Generic Lists

    - by David Johnson
    I have two generic lists, both containing different data, except 4 fields, which I want to compare to another list and find items that do not match in either list. I need to basically replace where it says equals below, with not equals! var unMatchedData = from liveLines in liveList join oldList in comapreSnapshotList on new {liveLines.ClientNo, liveLines.SequenceNo, liveLines.LineNo, liveLines.Text} equals new {oldList.ClientNo, oldList.SequenceNo, oldList.LineNo, oldList.Text} select new KNOWTXTS { ClientNo = liveLines.ClientNo, SequenceNo = liveLines.SequenceNo, LineNo = liveLines.LineNo, Text = liveLines.Text };

  • Fill 4 input with one textarea

    - by Patrice Poliquin
    I have a question for the community. My problem is that I have 4 input files with a maxlength of 60 caracters for a total of 240 caracters. Because the "backend" of the customer's system, it need to be 4 differents inputs max to be inserted and they say it is not user-friendly to fill 4 fields. My solution I want to make a textarea and when you fill it, il complete the 4 fields. [input text #1] max60 [input text #2] max60 [input text #3] max60 [input text #4] max60 [textarea max 240] What I am trying to do is to make by javascript/jQuery to fill up the four field while typing in. At the moment, here is my code. $(document).ready(function() { // My text area $("#inf_notes").bind('keydown', function () { var maxLength = 240; if ($(this).val().length <= 60) { // The first 60 caracters $('#inf_notes_1').val($(this).val()); } if ($(this).val().length > 60 && $(this).val().length <= 120) { // If more then 60, fill the second field $('#inf_notes_2').val($(this).val()); } // If 121 - 180 ... // If 181 - 240 ... if($(this).val().length == 240) { $(this).val($(this).val().substring(0, maxLength)); $('.alert_textarea').show(); // Simple alert else { $('.alert_textarea').hide(); } }); }); It actually works for the first one, but I would like to have some feedbacks to help me complete the script to fill the 3 nexts. Any guess to complete it? -- EDIT #1 I found a way that could maybe work! When the first input is completly filled, it will jump to the next field with a .focus() $(".inf_notes").bind('keydown', function () { var notes1 = $('#inf_notes_1').val(); var notes2 = $('#inf_notes_2').val(); var notes3 = $('#inf_notes_3').val(); if (notes1.length == 60) { $('#inf_notes_2').focus(); } if (notes2.length == 60) { $('#inf_notes_3').focus(); } if (notes3.length == 60) { $('#inf_notes_4').focus(); } });

  • Why should Java ThreadLocal variables be static

    - by kellyfj
    I was reading that JavaDoc for Threadlocal here http://java.sun.com/j2se/1.5.0/docs/api/java/lang/ThreadLocal.html and it says "ThreadLocal instances are typically private static fields in classes that wish to associate state with a thread (e.g., a user ID or Transaction ID). " But my question is why did they choose to make it static (typically) - it makes it a bit confusing to have "per thread" state but its static?

  • SQLAlchemy: an efficient/better select by primary keys?

    - by hadrien
    Yet another newbie question.. Let's say I have an user table in declarative mode: class User(Base): __tablename__ = 'user' id = Column(u'id', Integer(), primary_key=True) name = Column(u'name', String(50)) When I have a list of users identifiers, I fetch them from db with: user_ids = [1, 2, 3, 4, 5] users = Session.query(User).filter(User.id.in_(user_ids)).all() I dislike using in_ because I think I learned it has bad performance on indexed fields (is that true/false?). Anyway, is there a better way doing that query? Thanks!

  • Iterating through struct fieldnames in MATLAB.

    - by Noio
    My question is easily summarized as: "Why does the following not work?" teststruct = struct('a',3,'b',5,'c',9) fields = fieldnames(teststruct) for i=1:numel(fns) fns(i) teststruct.(fns(i)) end output: ans = 'a' ??? Argument to dynamic structure reference must evaluate to a valid field name. Especially since teststruct.('a') does work. And fns(i) prints out ans = 'a'. I can't get my head around it.

  • How to implement a login page in a GWT app?

    - by Gatis
    My WebApp needs to authenticate user before allowing any sort of access. The scenario I'm trying to implement is a login page with username and password fields. Once user hits "send" button, a sign like "Verifing..." should be shown up while an RPC call verifies credentials. In case of success, load the main app screen. What is the best way to implement that?

    - by rantravee
    Hi, I'm hoping that someone will explain to me what preferred access point name refers to in the android system , and what is it's role . Also I'd like to know if by messing with all APN (adding a suffix to the "apn" and "type" fields to disable 3G/EDGE/GPRS connections , and the deleting this suffix ) , the preferred APN can be disrupted. Also if it need special settings in case an APN manipulation is desired.

  • How to pass data between controls and persist the values in WPF

    - by randyc
    I am stuck on how to pass data from one control to another. If I have a listbox control and the Contol Item contains a datatemplate which renders out 5 fields ( first name, last name, email, phone and DOB) all of which come from an observable collection. How can I allow the user to select a listbox item and have the valuesbe stored within a new listbox control? Is this done through the creation of a new collection or is there a more simple way to bind these values to a new control? thank you,

  • @Unique doesn't have any effect in DataNucleus w/ NeoDatis

    - by David Parks
    Using JDO / DataNucleus / NeoDatis datastore I added @Unique to a field of a persistable object, however I am allowed to create multiple objects which violate the unique constraint. The docs for DataNucleus/NeoDatis suggest that Unique fields are supported. @PersistenceCapable public class User { @Persistent @Unique private String username; //... } If I add multiple objects to the DB with the same username there's no problem doing so. :(
