• Getting the value from an array in the model in rails

  - by slythic

  Hi all, I have a relatively simple problem. I have a model named Item which I've added a status field. The status field will only have two options (Lost or Found). So I created the following array in my Item model: STATUS = [ [1, "Lost"], [2, "Found"]] In my form view I added the following code which works great: <%= collection_select :item, :status, Item::STATUS, :first, :last, {:include_blank => 'Select status'} %> This stores the numeric id (1 or 2) of the status in the database. However, in my show view I can't figure out how to convert from the numeric id (again, 1 or 2) to the text equivalent of Lost or Found. Any ideas on how to get this to work? Is there a better way to go about this? Many thanks, Tony

• IE6 forces Two clicks to trigger javascript style=display:inline; event

  - by JiminyCricket

  I have a web form that has 2 radio buttons, depending on which one is clicked it displays a hidden element This works fine in all browsers except for IE6, which, after I click on the radio button, I have to click again (anywhere on the window) and then the element is displayed...has anyone had behavior like this before? I tried to not use jQuery and do straight getElementById() but I get the same behavior... JSCRiPT function showHidden(divid) { $('#'+divid).css( {'display':'inline'} ); } HTML <input type=radio name=borp value=1 onChange='showHidden("brandchecks")' > Brand <input type=radio name=borp value=2 onChange='showHidden("productchecks")' > Product <div id='brandchecks' style='display:none;'> Blah </div> <div id='productchecks' style='display:none;'> Blah </div>

• Is this an injection attempt or a normal request?

  - by CheeseConQueso

  In cPanel's Analog Stats statistics module, I've noticed countless requests to connect to the following example: /?x=19&y=15 The numbers are random, but its always setting x and y variables. Another category of mysterious requests: /?id=http://nic.bupt.edu.cn/media/j1.txt?? There are other attempts at injections in the request log that have straight sql written into them as well. Example: /jobs/jobinfo.php?id=-999.9 UNION ALL SELECT 1,(SELECT concat(0x7e,0x27,count(table_name),0x27,0x7e) FROM information_schema.tables WHERE table_schema=0x73636363726F6F745F7075626C6963),3,4,5,6,7,8,9,10,11,12,13-- It looks like they are all reaching a 404, but I'm still wondering about the intent behind these. I know this is vague, but maybe someone knows that this is normal while using cPanel & phpMyAdmin services. Also, there was a search box installed on the site which could be the reason. Any suggestions as to what all these are?

• How to manage different form contexts of same form element in single DOM tree

  - by nimp

  Hi, As my question title could be bit unclear to you (I tried best), following is what I'm exactly trying to do. I'm having a form element (say a user_info form), where such form elements will be generated for different users by java script and displayed in different js tabs (example: dojo tabs). once form elements are generated, later I need to react on user actions performed on different html elements defined inside user_info form. In this case I need to identify what is the context (in which user_info form element) in which user is working on. The simplest example would be how to retrieve form id of the form in which user actions are being performed. According to my understanding, I can not simply retrieve from by form id, because now DOM tree contains duplicate form instances of the same from element. So, IS there anyway, I could identify form context based on the user actions on its input elements. Thank You.

• Setting parameters after obtaining their values in stored procedures

  - by user1260028

  Right now I have an upload field while uploads files to the server. The prefix is saved so that it can later be obtained for retrieval. For this I need to attach the ID of the form to the prefix. I would like to be able to do this as such: @filePrefix = SCOPE_IDENTITY() + @filePrefix; However I am not so sure this would work because the record has not been created yet. If anything I could call an update function which obtains the ID and then injects it into the row after it has been created. To speed things up, I don't want to do this on the server but rather do this on the database. Regardless of what the approach is, I would still like to know if something like the above is possible (at least for future reference?) So if we replace that with @filePrefix = 5 + @filePrefix; would that be possible? SQL doesn't seem to like the current syntax very much...

• EntityFramework: using association or add property manualy

  - by dritterweg

  I'm starting to use Entity Framework. Let's say I have to Entity from my tables in DB. Here is the table schema Profiles ProfileId FirstName LastName Hobbies Id HobbyName OwnerId So one profile can have many hobbies. My Entity Framework: ProfileEntity ProfileId FirstName LastName Hobbies (collection of HobbyEntity) note: this created by the Association tool HobbyEntity Id HobbyName Owner (type of ProfileEntity) note: this created by the Association tool, for me this property is not important my question: should I use the "Association" tool to make the relationship between the two entities, which in result create a property of each entity (in ProfileEntity will create a HobbyEntity and vica versa) or should I not use the association and only add a scalar property manually such as List<HobbyEntity> in my ProfileEntity and OwnerId in HobbyEntity.

• Wrapping pre-made elements using GWT?

  - by user246114

  Hi, I've been working with GWT for awhile, I can't find a way to integrate it with a preexisting website which is a real downer. My page content is already generated for me using jsp, like: <div id='A'></div> <div id='B'></div> etc. there is no way for me to do something like this though: public void onModuleLoad() { SimplePanel spA = new SimplePanel( Document.getElementById("A")); spA.add(new Label("hello")); SimplePanel spB = new SimplePanel( Document.getElementById("B")); spB.setWidth("200px"); etc .. } seems like there's no way to just wrap a pre-existing element. Is this true, or am I missing how to do this? I need be able to wrap a bunch of elements like this, to manipulate them later on. I see TextBox, Button, a few other classes have wrap() methods, however nothing like that exists for elements, Thanks

• mysql database design: thread and reply of a reply?

  - by ajsie

  in my forum i have threads and replies. one thread has multiple replies. but then, a reply can be a reply of an reply (like google wave). because of that a reply has to have a column "reply_id" so it can point to the parent reply. but then, the "top-level" replies (the replies directly under the thread) will have no parent reply. so how can i fix this? how should the columns be in the reply table (and thread table). at the moment it looks like this: threads: id title body replies: id thread_id (all replies will belong to a thread) reply_id (here lies the problem. the top-level replies wont have a parent reply) body what could a smart design look like to enable reply a reply?

• Securing database keys for client-side processing

  - by danp

  I have a tree of information which is sent to the client in a JSON object. In that object, I don't want to have raw IDs which are coming from the database. I thought of making a hash of the id and a field in the object (title, for example) or a salt, but I'm worried that this might have a serious effect on processing overhead. SELECT * FROM `things` where md5(concat(id,'some salt')) = md5('1some salt'); Is there a standard practice for obscuring IDs in this kind of situation?

  Hi I have this SP USE [TestDB] GO /****** Object: StoredProcedure [dbo].[sp_test] Script Date: 06/12/2010 11:47:27 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[sp_test] @id uniqueidentifier AS BEGIN select * from TestTbl where ProductId= @id END I then went to the SP with ms sql 2005 and clicked execute. It comes up with a box where I entered in the GUID. I copied and pasted it straight from my test database. I get this error. Msg 102, Level 15, State 1, Line 5 Incorrect syntax near 'cac671b'. So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

• Two methods with different signatures, jquery is not calling correct method

  - by Lee

  There are two methods GetUserAssignedSystems() and GetUserAssignedSystems(string Id) These methods act very differently from each other. The problem is, when I want to call GetUserAssignedSystems(string Id), the parameter-less method is called. Here are the methods: [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems(string cacId) { return Data.UserManager.GetUserAssingedSystems(cacId); } [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems() { //do something else } Here is the jquery making the call: CallMfttService("ServiceLayer/UserManager.asmx/GetUserAssignedSystems", "{'cacId':'" + $('#EditUserCacId').val() + "'}", function(result) { for (var userSystem in result.d) { $('input[UserSystemID=' + result.d[userSystem] + ']').attr('checked', 'true'); } }); Any ideas why this method is being ignored?

• Basic SQL query question

  - by user318573

  Hello, I have the following query: SELECT Base.ReportDate, Base.PropertyCode, Base.FirstName, Base.MiddleName, Base.LastName, Person.FirstName, Person.MiddleName, Person.LastName FROM LeaseT INNER JOIN Base ON LeaseT.LeaseID = Base.LeaseID INNER JOIN Person ON LeaseT.TenantID = Person.ID works fine, except there could be 0 to 'N' people in the 'Person' table for each record in the Base table, but I only want to return exactly 1 for each 'Base' record (doesn't matter which, but the one with the lowest Person.ID) would be a reasonable choice. If there is 0 rows in the person table, I still need to return the row, but with null values for the 'person' fields. How would I structure the SQL to do that? Thanks. Edit: Yes, the tables are probably not structured properly, but restructuring at this time is not possible - got to work with what is there.
