  • Rails Load Data into Application every time a New User is Created

    - by looloobs
    Hi I am trying to figure out the "right" way to do this. In my application every time I create a new user I want to have specific data loaded into an associated table. The associated table is a different preset lists. So a User has many lists and those lists have many items. Some of those Items I want to be loaded when the User is created. I really don't know how to go about doing this but I am guessing something like: create User after_create: create Lists (need already existing data for the list names) after_create List then populate Items table with existing data for these Lists. Should I be using seed data for this? Is that alright for production and if so how exactly would I go about doing that. Any guidance or other recommendations are greatly appreciated.

  • PHP - Drilling down Data and Looping with Loops

    - by stogdilla
    I'm currently having difficulty finding a way of making my loops work. I have a table of data with 15 minute values. I need the data to pull up in a few different increments $filters=Array('Yrs','Qtr','Day','60','30','15'); I think I have a way of finding out what I need to be able to drill down to but the issue I'm having is after the first loop to cycle through all the Outter most values (ex: the user says they want to display by Hours, each hour should be able to have a "+" that will then add a new div to display the half hour data, then each half hour data have a "+" to display the 15 minute data upon request. Now I can just program the number of outputs for each value (6 different outputs) just in-case... but isn't there a way I can make it do the drill down for each one in a loop? so I only have to code one output once and have it just check if there are any more intervals after it and check for those? I'm sure I'm just overlooking some very simple way of doing this but my brain isn't being clever today. Sorry in advance if this is a simple solution. I guess the best way I could think of it as a reply on a form. How you would check to see if it's a reply of a reply, and then if that reply has any replys...etc for output. Can anyone help or at least point me in the right direction? Or am I stuck coding each possible check? Thanks in advance!

  • Error: Get JSON Data from Web API Using Jquery

    - by Kenneth
    I'm really new at this. And I'm really stuck. I have the jquery code, it will load data from Web API, but it does not display on my page. $.getJSON("/api/Order", function(data) { if (data != null) { var str = ''; $.each(data, function (item) { str = '<li>' + item.ItemName + '</li>'; }); $("#contents").append(str); } }); Can anyone explain what is going on? Thanks.

  • Using Remote Web Server to Initialize iPhone App

    - by Chris_K
    My iPhone app relies on a vendor's XML feed to provide data. But that feed is not locked down. The vendor could change the format of the XML at any time, although so far they've promised not to. Since I might want to tell my app to use a different URL for its data source, I'd like to set up a single "Command Central" Web page, on my own server, to direct the app to the correct data source. In other words, each time my app starts, in the background and unseen by the user, it would visit "http://www.myserver.com/iphoneapp_data_sources.xml" to retrieve the URL for retrieving data from my vendor. That way, if my vendor suddenly changes the exact URL or the XML feed that the app needs, I can update that Web page and ensure that all installations of the app are using the correct XML feed. Does anyone have any advice or examples showing this kind of approach? It seems as if this must be a common problem, but so far I haven't found a well-established design pattern that fits it.

  • Pulling $_GET data and creating multidimensional array using loop

    - by Chris J
    I'm creating a checkout for customers and the data about what's in their cart is being sent to a page (for just now) via $_GET. I want to extract that data and then populate a multidimensional array with it using a loop. Here's how I'm naming the data: $itemCount = $_GET['itemCount']; $i = 1; while ($i <= $itemCount) { ${'item_name_'.$i} = $_GET["item_name_{$i}"]; ${'item_quantity_'.$i} = $_GET["item_quantity_{$i}"]; ${'item_price_'.$i} = $_GET["item_price_{$i}"]; //echo "<br />Name: " .${'item_name_'.$i}. " - Quantity: " .${'item_quantity_'.$i}. " - Price: ".${'item_price_'.$i}; $i++; } From here I'd like to create a multidimensional array like such: Array ( [Item_1] => Array ( [item_name] => Shoe [item_quantity] => 2 [item_price] => 40.00 ) [Item_2] => Array ( [item_name] => Bag [item_quantity] => 1 [item_price] => 60.00 ) [Item_3] => Array ( [item_name] => Parrot [item_quantity] => 4 [item_price] => 90.00 ) . . . ) What I'd like to know is if there is a way I can create this array in the existing while loop? I'm aware of being able to add data to an array like $data = [] after delacring an empty array but the actual syntax eludes me. Maybe I'm completely off the right track and there is a better way of doing it? Thanks

  • Fill data gaps - UNION, PARTITION BY, or JOIN?

    - by Dave Jarvis
    Problem There are data gaps that need to be filled. Would like to avoid UNION or PARTITION BY if possible. Query Statement The select statement reads as follows: SELECT count( r.incident_id ) AS incident_tally, r.severity_cd, r.incident_typ_cd FROM report_vw r GROUP BY r.severity_cd, r.incident_typ_cd ORDER BY r.severity_cd, r.incident_typ_cd Data Sources The severity codes and incident type codes are from: severity_vw incident_type_vw The columns are: incident_tally severity_cd incident_typ_cd Actual Result Data 36 0 ENVIRONMENT 1 1 DISASTER 27 1 ENVIRONMENT 4 2 SAFETY 1 3 SAFETY Required Result Data 36 0 ENVIRONMENT 0 0 DISASTER 0 0 SAFETY 27 1 ENVIRONMENT 0 1 DISASTER 0 1 SAFETY 0 2 ENVIRONMENT 0 2 DISASTER 4 2 SAFETY 0 3 ENVIRONMENT 0 3 DISASTER 1 3 SAFETY Question How would you use UNION, PARTITION BY, or LEFT JOIN to fill in the zero counts?

  • GPL and hosted services

    - by John
    As I understand it GPL says you only have to distribute derivative code for works you distribute, i.e. if you develop internal software you can keep your code private. What happens if you develop a server application, say like Facebook or StackOverflow? The server app is not 'distributed' so what's the situation with your code in this case?

  • Is there any complications or side effects for changing final field access/visibility modifier from private to protected?

    - by Software Engeneering Learner
    I have a private final field in one class and then I want to address that field in a subclass. I want to change field access/visibility modifier from private to protected, so I don't have to call getField() method from subclass and I can instead address that field directly (which is more clear and cohessive). Will there be any side effects or complications if I change private to protected for a final field? UPDATE: from logical point of view, it's obvious that descendant should be able to directly access all predecessor fields, right? But there are certain constraints that are imposed on private final fields by JVM, like 100% initialization guarantee after construction phase(useful for concurrency) and so on. So I would like to know, by changing from private to protected, won't that or any other constraints be compromised?

    My Android application stores all user data in a Sqlite database. What are my options to backup/export/import/copy this data? I know I can easily copy the database to the SD card. I would also like to send the data to a network server. Are there any packages/classes available to facilitate getting sqlite information to/from a network server? Thanks for the help...

  • XML Doc to JSP to TIFF

    - by SPD
    We have around 100 word templates, every time user gets a business request he goes into shared folder select the template he/she wants and enter information and save it as tiff, these tiffs later processed by some batch program. I am trying to automate this process. So I defined an XML which has Template information like <Template id="1"> <Section id="1"> <fieldName id="1">Date</fieldName> <fieldValue></fieldValue> <fieldtype></fieldType> <fieldProperty>textField</fieldProperty> </Section> <Section id="2"> <fieldName id="2">Claim#</fieldName> <fieldValue></fieldValue> <fieldtype></fieldType> <fieldProperty>textField</fieldProperty> </Section> </Template> Based on the template values I generate the JSP on fly. Now I would like to generate a TIFF file out of it in specified format. I am not sure how to handle this requirement. *edited the original question.

  • application specific seed data population

    - by user339108
    Env: JBoss, (h2, MySQl, postgres), JPA, Hibernate 3.3.x @Id @GeneratedValue(strategy = IDENTITY) private Integer key; Currently our primary keys are created using the above annotation. We expect to support a large number of users (~million users), what key should be used. Should it be Integer or Long or should I use the unsigned versions of the above declarations. We have a j2ee application which needs to be populated with some seed data on installation. On purchase, the customer creates his own data on top of the application. We just want to make sure that there is enough room to ship, modify or add data for future releases. What would be the best mechanism to support this, we had looked at starting all table identifiers from a certain id (say 1000) but this mandates modifying primary key generation to have table or sequence based generators and we have around ~100 tables. We are not sure if this is the right strategy for this. If we use a signed integer approach for the key, would it make sense to have the seed data as everything starting from 0 and below (i.e -ve numbers), so that all customer specific data will be available on 0 and above (i.e. +ve numbers)

  • What IRC client(s) would allow me to filter out log messages?

    - by Aras
    I have been using Empathy and more recently Pidgin as my IRC client. But there is one feature missing from both of these clients that keeps bothering me. I want to be able to see only what people are actually talking about in each channel. I often like to leave IRC channels open and go back to them and read the messages for the last few hours or days. I saw that IRC clients have been discussed in this post and a few others, but I have not found what I am looking for yet. Here is what I want to see in my IRC client: what actual people say Here is what I do not want to see message about people entering the room people leaving room people changing their status messages or what they are known as people sneezing people's cats sneezing Anyway, you get the picture. What IRC clients are available for Ubuntu that would allow me to configure what I see so that I can see what people are talking about -- and nothing else?

  • Reading in data from a file into an array

    - by Sam
    If I have an options file along the lines of this: size = 4 data = 1100010100110010 And I have a 2d size * size array that I want to populate the values in data into, what's the best way of doing it? To clarify, for the example I have I'd want an array like this: int[4][4] array = {{1,1,0,0}, {0,1,0,1}, {0,0,1,1}, {0,0,1,0}}. (Not real code but you get the idea). Size can be really be any number though. I'm thinking I'd have to read in the size, maloc an array and then maybe read in a string full of data then loop through each char in the data, cast it to an int and stick it in the appropriate index? But I really have no idea how to go about it, have been searching for a while with no luck. Any help would be cool! :)

  • Extracting Data Daily from MySQL to a Local MySQL DB

    - by Sunny Juneja
    I'm doing some experiments locally that require some data from a production MySQL DB that I only have read access to. The schemas are nearly identical with the exception of the omission of one column. My goal is to write a script that I can run everyday that extracts the previous day's data and imports it into my local table. The part that I'm most confused about is how to download the data. I've seen names like mysqldump be tossed around but that seems a way to replicate the entire database. I would love to avoid using php seeing as I have no experience with it. I've been creating CSVs but I'm worried about having the data integrity (what if there is a comma in a field or a \n) as well as the size of the CSV (there are several hundred thousand rows per day).

  • Cannot create a new VS data connection in Server Explorer

    - by Seventh Element
    I have a local instance of SQL Server 2008 express edition running on my development PC. I'm trying to create a new data connection through Visual Studio Server Explorer. The steps are the following: Right click the "Data Connections" node = Choose Data Source. I select "Microsoft SQL Server" as the data source. The "Add Connection" dialog window appears. I select my local server instance = "Test connection" works fine. I select "AdventureWorks" as the database name = "Test connection" works fine. Next I hit the "Ok" button = Error message: "This server version is not supported. Only servers up to MS SQL Server 2005 are supported." I'm using Visual Studio 2008 Professional Edition. The target framework of the application is ".NET framework 3.5". I have a reference to System.Data (framework v2.0) and cannot find another version of the assembly on my system. Am I referencing the wrong assembly? How can I fix this problem?

  • Migrating Data to MSSQL 2008

    - by Fred Clown
    I am trying to migrate data from an Informix database to MSSQL 2008. I've got quite a lot of data to move. I've been try multiple methods to get the data over, and so far SQLBulkCopy in multiple chunks seems to be the fastest that I can find. Does anyone know of a faster means of getting the data over? I'm trying to cut down on the transfer time so that on my cut-over date I don't run out of time to do the full cut-over. Thanks.
