  • Real-time data on webpage with jQuery

    - by Steven Hepting
    I would like a webpage that constantly updates a graph with new data as it arrives. Regularly, all the data you have is passed to the page at the beginning of the request. However, I need the page to be able to update itself with fresh information every few seconds to redraw the graph. Background The webpage will be similar to this http://www.panic.com/blog/2010/03/the-panic-status-board/. The data coming in will temperature values to be graphed measured by an Arduino and saved to the Django database (this part is already complete). Update It sounds as though the solution is to use the jQuery.ajax() function ( http://api.jquery.com/jQuery.ajax/) with a function as the .complete callback that will schedule another request several seconds later to a URL that will return the data in JSON format. How can that method be scheduled? With the .delay() function?

  • code igniter codeigniter question, making anchor load page containing data from referenced row in DB

    - by thrice801
    Hi, Im trying to learn the code igniter library and object oriented php in general and have a question. Ok so Ive gotten as far as making a page which loads all of the rows from my database and in there, Im echoing an anchor tag which is a link to the following structure. [code]echo anchor("videos/video/$row-video_id", $row-video_title);[/code] So, I have a class called Videos which extends the controller, within that class there is index and video, which is being called correctly (when you click on the video title, it sends you to videos/video/5 for example, 5 being the primary key of the table im working with. So basically all Im trying to do is pass that 5 back to the controller, and then have the particular video page output the particular rows data from the videos table. My function in my controller for video looks like this - [code] function video() { $data['main_content'] = 'video'; $data['video_title'] = 'test'; $this-load-view('includes/template', $data); } [/code] So ya, basically test should be instead of test, a returned value of a query which says get in the table "videos", the row with the video_id of "5", and make $data['video_title'] = value of video_title in database... Should have this figured out by now but dont, any help would be appreciated!

  • UnsupportedEncodingException thrown when using Resin and Grails

    - by knorv
    I've encountered a strange problem in a Grails webapp running under Grails: java.io.UnsupportedEncodingException is thrown quite frequently due to various unknown encoding strings (such as "ISO8859_10", "ISO-8859-10"), and the strange thing is that this is done entirely within the Resin and Grails code. That is - no custom code is involved when the exception is thrown. I'm not sure if it is Grails or the servlet container's code that should handle the exception. But I'd assume that the exception should be handled somewhere and not bubble up all the way to stderr. This is the exception in full: java.io.UnsupportedEncodingException: ISO-8859-10 at com.caucho.vfs.i18n.JDKWriter$OutputStreamEncodingWriter.<init>(JDKWriter.java:112) at com.caucho.vfs.i18n.JDKWriter.create(JDKWriter.java:79) at com.caucho.vfs.Encoding.getWriteEncoding(Encoding.java:231) at com.caucho.server.connection.ToByteResponseStream.setEncoding(ToByteResponseStream.java:137) at com.caucho.server.connection.AbstractHttpResponse.setLocale(AbstractHttpResponse.java:1683) at com.caucho.server.connection.HttpServletResponseImpl.setLocale(HttpServletResponseImpl.java: 115) at javax.servlet.ServletResponseWrapper.setLocale(ServletResponseWrapper.java:139) at javax.servlet.ServletResponseWrapper.setLocale(ServletResponseWrapper.java:139) at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1035) at org.codehaus.groovy.grails.web.servlet.GrailsDispatcherServlet.doDispatch(GrailsDispatcherServlet.java:290) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:647) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:552) at javax.servlet.http.HttpServlet.service(HttpServlet.java:114) My questions: Should the exception be handled? If so, is it the responsibility of the servlet container (Resin) or the web framework (Grails)? How would you go about solving this? (I'd rather not having the exception log cluttered with exceptions that I can do nothing about.)

  • Database solutions for storing/searching EXIF data

    - by webdestroya
    I have thousands of photos on my site (each with a numeric PhotoID) and I have EXIF data (photos can have different EXIF tags as well). I want to be able to store the data effectively and search it. Some photos have more EXIF data than others, some have the same, so on.. Basically, I want to be able to query say 'Select all photos that have a GPS location' or 'All photos with a specific camera' I can't use MySQL (tried it, it doesn't work). I thought about Cassandra, but I don't think it lets me query on fields. I looked at SimpleDB, but I would rather: not pay for the system, and I want to be able to run more advanced queries on the data. Also, I use PHP and Linux, so it would be awesome if it could interface nicely to PHP. Any ideas?

  • String Manipulation: Spliting Delimitted Data

    - by Milli Szabo
    I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 If the data is *Address 1*Address2, split will create two indexes in the array where index 0 will have the value of Address 1 and index 2 will have the value of Address2. Where's the name. Was there a name? Any suggestion?

  • JMS have javax.jms.InvalidDestinationException when client stop working

    - by Tran
    I use JMS for sending requests from a client to a server. My client sends a request to the server. While the server is working with my request, my client stops (network problem) before the server finishes. When the server is finished, it'll return to the client, but the server can't see the client which sent the request to server, at which point, the server will return an exception in log file. The exception is : javax.jms.InvalidDestinationException: Cannot publish to a deleted Destination: temp-queue://ID:PC0092-49463-1344231871819-0:0:9 [^] My question is: what do I need to do in this case? Can I catch or disable this exception? And how can I do it? (Sorry, If my english is not good.)

  • Definitive best practice for injecting, manipulating AJAX data

    - by Nic
    Ever since my foray into AJAX, I've always used the "whatever works" method of manipulating AJAX data returns. I'd like to know what the definitive and modern best practice is for handling data. Is it best practice to generate the HTML via the server script and introduce the returned data on the onComplete function? Should XML/JSON be looked at first before anything? How about manipulating the returned data? Using .live() doesn't seem like it is the most efficient way. I've never seen a definitive answer to this question. Your expertise is much appreciated.

  • PL/SQL - How to pull data from 3 tables based on latest created date

    - by Nancy
    Hello, I'm hoping someone can help me as I've been stuck on this problem for a few days now. Basically I'm trying to pull data from 3 tables in Oracle: 1) Orders Table 2) Vendor Table and 3) Master Data Table. Here's what the 3 tables look like: Table 1: BIZ_DOC2 (Orders table) OBJECTID (Unique key) UNIQUE_DOC_NAME (Document Name i.e. ORD-005) CREATED_AT (Date the order was created) Table 2: UDEF_VENDOR (Vendors Table): PARENT_OBJECT_ID (This matches up to the ObjectId in the Orders table) VENDOR_OBJECT_NAME (This is the name of the vendor i.e. Acme) Table 3: BIZ_UNIT (Master Data table) PARENT_OBJECT_ID (This matches up to the ObjectID in the Orders table) BIZ_UNIT_OBJECT_NAME (This is the name of the business unit i.e. widget A, widget B) Note: The Vendors Table and Master Data do not have a link between them except through the Orders table. I can join all of the data from the tables and it looks something like this: Before selecting latest order date: ORD-005 | Widget A | Acme | 3/14/10 ORD-005 | Widget B | Acme | 3/14/10 ORD-004 | Widget C | Acme | 3/10/10 Ideally I'd like to return the latest order for each vendor. However, each order may contain multiple business units (e.g. types of widgets) so if a Vendor's latest record is ORD-005 and the order contains 2 business units, here's what the result set should look like by the following columns: UNIQUE_DOC_NAME, BIZ_UNIT_OBJECT_NAME, VENDOR_OBJECT_NAME, CREATED_AT After selecting by latest order date: ORD-005 | Widget A | Acme | 3/14/10 ORD-005 | Widget B | Acme | 3/14/10 I tried using Select Max and several variations of sub-queries but I just can't seem to get it working. Any help would be hugely appreciated!

  • Hibernate orm for a view

    - by EugeneP
    How do you ORM a view? Is there any difference with a table in terms of reverse engineering? In my case, I have a whole pile of joined tables that will be read-only in an application. So, if I need sort of a 1 Object with all collections in proper order, instead of long chains of relationships - collection with another etc, it'll be simpler. What do you think and how do you accomplish this?

Now after sometimes I have heard from someone that I might lost some data while this process on soap service created in ASP.net. So now I have decided to send and receive data through batches like first I will send List of 50 objects and then next 50 and so on... Now I am new to web services and all.

By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.
