  • Receive JSON payload with ZEND framework and / or PHP

    - by kent3800
    I'm receiving a JSON payload from a webservice at my site's internal webpage at /asset/setjob. The following is the JSON payload being posted to /asset/setjob: [{"job": {"source_filename": "beer-drinking-pig.mpg", "current_step": "waiting_for_file", "encoding_profile_id": "nil", "resolution": "nil", "status_url": "http://example.com/api/v1/jobs/1.json", "id": 1, "bitrate": "nil", "current_status": "waiting for file", "current_progress": "nil", "remote_id": "my-own-remote-id"}}] This payload posts one time to this page. The page is not meant for viewing but parsing the JSON object for the id and current_status so that I can insert it into a database. I'm using Zend framework. HOW DO I receive this payload in Zend? Do I $_GET['json']? $_POST['job']? None of these seem to work. I essentially need to assign this payload to a php variable so that I can then manipulate it. I've tried: $jsonStrGet = var_dump($_GET); $jsonStrPost = var_dump($_POST); And I've tried: $response = $this-getResponse(); $body = $response-getBody(); Blockquote Any help would be much appreciated! Thanks.

  • Mapping an instance of IList in NHibernate

    - by Martin Kirsche
    I'm trying to map a parent-child relationship using NHibernate (2.1.2), MySql.Data (6.2.2) and MySQL Server (5.1). I figured out that this must be done using a <bag> in the mapping file. I build a test app which is running without yielding any errors and is doing an insert for each entry but somehow the foreign key inside the children table (ParentId) is always empty (null). Here are the important parts of my code... Parent public class Parent { public virtual int Id { get; set; } public virtual IList<Child> Children { get; set; } } <class name="Parent"> <id name="Id"> <generator class="native"/> </id> <bag name="Children" cascade="all"> <key column="ParentId"/> <one-to-many class="Child"/> </bag> </class> Child public class Child { public virtual int Id { get; set; } } <class name="Child"> <id name="Id"> <generator class="native"/> </id> </class> Program using (ISession session = sessionFactory.OpenSession()) { session.Save( new Parent() { Children = new List<Child>() { new Child(), new Child() } }); } Any ideas what I did wrong?

  • iphone: unrecognized selector sent to instance

    - by eshalev
    I am new to objective C, So maybe there is some basic thing that I am missing about selectors. I would like to understand the basic concept behind this error as I have not found an general error reference. I am getting this error when using: [CloseButton addTarget:PageContents action:@selector(CloseButtonPressed) forControlEvents:UIControlEventTouchUpInside]; and then later: - (void)CloseButtonPressed:(id)sender{ UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Comment" message: @"hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; }

  • Reading PGP key information

    - by calccrypto
    can someone show a description of the information of what a pgp looks like if only the descriptions were there but not the actual information? something like (i dont remember if the values are correct): packet-type[4 bits], total length in bytes[16 bits], packet version type [4 bits], creation-time[32 bits], encryption-algorithm[8 bits], ...,etc,etc ive tried to understand rfc4880, but its tedious and confusing. so far, i am think i have extracted the 4 i wrote above, but i cant seem to get the rest of the information out. can anyone help? i know i can just find some pgp program, but the whole point of this is to allow me to learn how those programs work in the first place

  • django simple approach to multi-field search

    - by Scott Willman
    I have a simple address book app that I want to make searchable. The model would look something like: class Address(models.Model): address1 = models.CharField("Address Line 1", max_length=128) address2 = models.CharField("Address Line 2", max_length=128) city = models.CharField("City", max_length=128) state = models.CharField("State", max_length=24) zipCode = models.CharField("Zip Code", max_length=24) def __unicode__(self): return "%s %s, %s, %s, %s" % (self.address1, self.address2, self.city, self.state, self.zipCode) class Entry(models.Model): name = models.CharField("Official School Name", max_length=128) createdBy = models.ForeignKey(User) address = models.ForeignKey(Address, unique=True) def __unicode__(self): return "%s - %s, %s" % (self.name, self.address.city, self.address.state) I want the searching to be fairly loose, like: Bank of America Los Angeles 91345. It seems like I want a field that contains all of those elements into one that I can search, but that also seems redundant. I was hoping I could add a method to the Entry model like this: def _getSearchText(self): return "%s %s %s" % (self.name, self.address, self.mascot) searchText = property(_getSearchText) ...and search that as a field, but I suppose that's wishful thinking... How should I approach this using basic Django and SqLite (this is a learning exercise). Thank you!!

  • Why is Firefox prompting to download a file that is POST'd to?

    - by alex
    This is the most peculiar thing. It is from an old in house CMS. When I attempt to submit my changes, it prompts to save the file linked in the action attribute of the form. Headers Request POST /~site/edit/articles/article_save.php?id=54 HTTP/1.1 Host: example.com User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://example.com Content-Type: multipart/form-data; boundary=---------------------------10102754414578508781458777923 Content-Length: 940 -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="title" Home Content -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="catid" 18 -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="activecheck" 1 -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="image" -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="contentWidgToolbarSelectBlock" <p> -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="content" <p>Edit your article in this text box.</p> -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="contentWidgEditor" true -----------------------------10102754414578508781458777923-- Response HTTP/0.9 200 OK And then Firefox shows.... I can't determine from the response headers as to why this is prompting to open/save. It has always worked. All other PHP files on the site work fine. Anyone have a clue?

  • Persisting a single UISearchBar instance across 4 separate UITableViews

    - by Jacob Relkin
    Hi fellas, I'm in the midst of an iPhone app that needs to have 4 separate UITableView objects sharing access to one UISearchBar in the first section and first row of the aforementioned UITableView objects. I have tried to offset the UITableView's frame by 44 pixels, then adding the search bar as a subview of my UIViewController's view. That works, but I cannot use the table index to scroll up to the search bar, since it is not a cell in the tableview. I need to have the search bar in the table view itself. My goal is to have the same UISearchBar in the first section of multiple tableviews. Thanks so much.

  • Can django lazy-load fields in a model?

    - by Leopd
    One of my django models has a large TextField which I often don't need to use. Is there a way to tell django to "lazy-load" this field? i.e. not to bother pulling it from the database unless I explicitly ask for it. I'm wasting a lot of memory and bandwidth pulling this TextField into python every time I refer to these objects. The alternative would be to create a new table for the contents of this field, but I'd rather avoid that complexity if I can.

  • Entity Framework 4 - Delay Loading Expensive Fields

    - by JohnnyO
    I know this same question was asked for Entity Framework 1, but now that Entity Framework 4 has come out, and Microsoft claims that it provides all of the features of Linq to Sql + more, does Entity Framework now support lazy loading expensive properties? In Linq to Sql, this is extremely easy. There's a Delay Loaded option on any property (accessible through the Designer) that can simply be toggled on or off. Is there something similar in Entity Framework? Thanks

  • PHP Overloading, singleton instance

    - by jamalali81
    I've sort of created my own MVC framework and am curious as to how other frameworks can send properties from the "controller" to the "view". Zend does something along the lines of $this->view->name = 'value'; My code is: file: services_hosting.php class services_hosting extends controller { function __construct($sMvcName) { parent::__construct($sMvcName); $this->setViewSettings(); } public function setViewSettings() { $p = new property; $p->banner = '/path/to/banners/home.jpg'; } } file: controller.php class controller { public $sMvcName = "home"; function __construct($sMvcName) { if ($sMvcName) { $this->sMvcName = $sMvcName; } include('path/to/views/view.phtml'); } public function renderContent() { include('path/to/views/'.$this->sMvcName.'.phtml'); } } file: property.php class property { private $data = array(); protected static $_instance = null; public static function getInstance() { if (null === self::$_instance) { self::$_instance = new self(); } return self::$_instance; } public function __set($name, $value) { $this->data[$name] = $value; } public function __get($name) { if (array_key_exists($name, $this->data)) { return $this->data[$name]; } } public function __isset($name) { return isset($this->data[$name]); } public function __unset($name) { unset($this->data[$name]); } } In my services_hosting.phtml "view" file I have: <img src="<?php echo $this->p->banner ?>" /> This just does not work. Am I doing something fundamentally wrong or is my logic incorrect? I seem to be going round in circles at the moment. Any help would be very much appreciated.

  • Storing dynamic fields in Django forms

    - by hekevintran
    Django's form library has a feature of form sets that allow you to process dynamically added forms. For example you would use form sets if your application has a list of bookmarks you could use form sets to process multiple forms that each represent a bookmark. What about if you want to dynamically add a field to a form? An example would be a survey creation page where you can dynamically add an unlimited number of questions. How do you handle this in Django?

  • Converting a C# DataTable instance to xml that contains HTML or binary data

    - by Wardy
    Hmmmm ... Although it works in most cases, one column has html data in it. It seems that doing this ... StringBuilder xmltarget = new StringBuilder(); XmlWriter xmlWriter = XmlWriter.Create(xmltarget); tableData.WriteXml(xmlWriter); ... doesn't identify where this html or binary data exists and wrap the data in cdata tags as it should ... Is there something i need to do to ensure the relevant checks are made and a working xml string is produced?

  • SQL update fields of one table from fields of another one.

    - by Nir
    I'm having two tables: A [ID, column1, column2, column3] B [ID, column1, column2, column3, column4] A table will always be subset of B table (meaning all columns of A are also in B). I want to update a record with a specific ID in B with their data from A for all columns of A. This ID exists both in A and B. Is there an UPDATE syntax or any other way to do that without specifying the column names, just saying "set all columns of A"? I'm using postgresql, so a specific non-standard command is also accepted (however, not preferred). Thanks.

  • Help Forming An SQL Query That Selects The Max Difference Of Two Fields

    - by Frank
    I'm trying to select a record with the most effective votes. Each record has an id, the number of upvotes (int) and the number of downvotes (int) in a MySQL database. I know basic update, select, insert queries but I'm unsure of how to form a query that looks something like: SELECT * FROM topics WHERE MAX(topic.upvotes - topic.downvotes). Please excuse my made up SQL. The tutorials on SQL I find on the internet cover very basic stuff. Does anyone recommend a good book on this subject?

  • How to return a value when destroying/cleaning-up an object instance

    - by Mridang Agarwalla
    When I initiate a class in Python, I give it some values. I then call method in the class which does something. Here's a snippet: class TestClass(): def __init__(self): self.counter = 0 def doSomething(self): self.counter = self.counter + 1 print 'Hiya' if __name__ == "__main__": obj = TestClass() obj.doSomething() obj.doSomething() obj.doSomething() print obj.counter As you can see, everytime I call the doSomething method, it prints some text and increments an internal variable i.e. counter. When I initiate the class, i set the counter variable to 0. When I destroy the object, I'd like to return the internal counter variable. What would be a good way of doing this? I wanted to know if there were other ways apart from doing stuff like: accessing the variable directly. Like obj.counter. creating a method like getCounter. Thanks.
