  • OOP + MVC advice on Member Controller

    - by dan727
    Hi, I am trying to follow good practices as much as possible while I'm learning using OOP in an MVC structure, so i'm turning to you guys for a bit of advice on something which is bothering me a little here. I am writing a site where I will have a number of different forms for members to fill in (mainly data about themselves), so i've decided to set up a Member controller where all of the forms relating to the member are represented as individual methods. This includes login/logout methods, as well as editing profile data etc. In addition to these methods, i also have a method to generate the member's control panel widget, which is a constant on every page on the site while the member is logged in. The only thing is, all of the other methods in this controller all have the same dependencies and form templates, so it would be great to generate all this in the constructor, but as the control_panel method does not have the same dependencies etc, I cannot use the constructor for this purpose, and instead I have to redeclare the dependencies and same template snippets in each method. This obviously isn't ideal and doesn't follow DRY principle, but I'm wondering what I should do with the control_panel method, as it is related to the member and that's why I put it in that controller in the first place. Am I just over-complicating things here and does it make sense to just move the control_panel method into a simple helper class? Here are the basic methods of the controller: class Member_Controller extends Website_Controller { public function __construct() { parent::__construct(); if (request::is_ajax()) { $this->auto_render = FALSE; // disable auto render } } public static function control_panel() { //load control panel view $panel = new View('user/control_panel'); return $panel; } public function login() { } public function register() { } public function profile() { } public function household() { } public function edit_profile() { } public function logout() { } }

  • Add a smaller subView with new origin

    - by ReachWest
    I can't get my head around this - I know it must be simple.. I'm starting to feel pretty stupid. I have two viewControllers. MainViewController.h/m and LevelsViewController.h/m I want to add a subView from the LevelsViewController class and a view that is built in IB called levelsView. I am calling this from the MainViewController.m file. The levelsView is only 200x200 pixels and I want to offset it from the frame origin of the superView by x=140 pixels and y=50 pixels. I have this working - the view displays, but I can't figure out how to offset it. It only shows up at the 0,0 superView frame origin. (The superView shows below it, which is what I want). Here is the code I call in the method in the MainViewController.m that displays the levelsView.(I have commented out some of the things I have tried - but throws this error: error: request for member 'frame' in 'myLevelsView', which is of non-class type 'LevelsViewController*' ) - (void) displayLevelsPage { if (self.theLevelsView == nil) // Does not yet exist - therefore create { LevelsViewController * myLevelsView = [[LevelsViewController alloc] initWithNibName:@"levelsView" bundle:[NSBundle mainBundle]]; NSLog(@"NEW theLevelsView instance created!"); CGRect frame2 = CGRectMake(140, 50, 200, 200); //myLevelsView.frame = frame2; self.theLevelsView = myLevelsView; [myLevelsView release]; } [self.view addSubview: theLevelsView.view]; NSLog(@"Levels View has been activated"); } Any insight would be appreciated.

  • Call to a member function ... on a non-object

    - by jayceekay
    i have an object which is instantiated in an initialize file, which is called with every request. the name is right, so why is it telling me that oourls isn't an object and that redirectLoggedIn isn't its method? a var dump on oourls says NULL. but it's instantiated, and the backtrace at the bottom shows that it goes through initialization and instantiates it. pretty small snippet of code, here's the relevant bit: if($email) { global $session; $session->grantLogin($email); global $oourls; $oourls->redirectLoggedIn(); } else { return false; } and here's the output of debug_print_backtrace i threw in above the oourls method call because i'm completely confused: #0 accounts::verifyEmailRegisterAccount(37a6274c8f4bfa5c537b40e8e04d634a) called at [\public\includes\default\verifyemail.php:16] #1 require_once(\public\includes\default\verifyemail.php) called at [\support\php\ObjectOrientedURLs.class.php:48] #2 ObjectOrientedURLs->mhqqrVerifyemail(Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) #3 ReflectionMethod->invoke(ObjectOrientedURLs Object (), Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) called at [\support\php\ObjectOrientedURLs.class.php:280] #4 ObjectOrientedURLs->parseAndInvokeURL() called at [\support\php\ObjectOrientedURLs.class.php:255] #5 ObjectOrientedURLs->__construct() called at [\support\php\initialize.php:76] #6 require_once(\support\php\initialize.php) called at [\public\index.php:2]

  • MVC2 AJAX - determining UpdateTargetId based on the returned data

    - by DanielJW
    The scenario: I'm creating a login form for an MVC2 application. How i'm doing it: The form submits to an MVC2 action which validates the username/password. If it fails validation the action returns the form (a partial view) for the user to try again. If it passes validation the action returns the page the user was visiting before they logged in (a view). What i want to happen: 1 - when the form is submitted and the user validates successfully, The returned result should replace the current page (like what happens if you don't set an UpdateTargetId). 2 - When the form is submitted and the user fails validation, the returned result should replace the form (like what happens if you set the UpdateTargetID to the form's containing element). The problem: I can make both of those things work, but not at the same time. I can either have it always replace the current page, or always just replace the contents of the UpdateTargetId element. But I need it to be able to do either depending on whether the user successfully validated or not. What I need The ideal solution would be to be able to examine the result of the ajax request and determine whether to use the UpdateTargetId (replacing just the form) or not (replacing the whole page). I expect it would involve some work with jquery (assuming it's possible) but i'm not really that great with jquery yet to figure out how to do it myself. If it can't be done this way I'm also open to other methods/solutions for making it work in a similar fashion. Thanks in advance ..

  • How can I load a div in rails in response to clicks on another div?

    - by mmr
    I'm very new to Rails (and web) programming, so I'm not even sure what technology I should be looking for for this. I've downloaded and run through the first five chapters of the Rails tutorial, but now have a very simple request. On the left hand side of a web page, I will have a table. If the user clicks on an element in that table, I want to have the right hand side of the page show something new. I already have a page to display the table, viz: <div class="center hero-unit"> <div class="container"> <h2>2012 Yearly Report</h2> <div class="row-fluid"> <div class="span12"> <div class="span4"> <table border="1"> </table> </div> <div class="span6"> <!-- load stuff here based on what someone clicks on in the table --> </div> </div> </div> </div> </div> And I'm using bootstrap layouts to display everything. I just don't understand how to change the contents of the 'span6' div based on user behavior in 'span4'.

  • How can I save a file on an http server using just http requests and javascript?

    - by user170902
    hi all, I'm trying to understand some of the basics of web servers/html/javasacript etc. I'm not interested in any of the various frameworks like php/asp, i'm just trying to get a low level look at things (for now). At the moment I'm trying to understand how data can be sent to/saved on the backend, but i must admit that i'm getting a bit lost under the various specs/technical stuff on w3 at the moment! If I have some data, say xml, that I want to save on the backend how do I go about it? I assume that I would have to use something like an HTTP PUT or POST Request to an html doc that contains some javascript that in turn would process the data, e.g. save it somewhere. Now from googling around I can see that this doesn't seem to be the case, so my assumptions are completely wrong! So how is it done? Can it be done, or do I have to use something like php or asp? TIA. bg

  • Django - Problem with models/manager to organise a query...

    - by user296644
    Hi, I have an application to count the number of access to an object for each website in a same database. class SimpleHit(models.Model): """ Hit is the hit counter of a given object """ content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') site = models.ForeignKey(Site) hits_total = models.PositiveIntegerField(default=0, blank=True) [...] class SimpleHitManager(models.Manager): def get_query_set(self): print self.model._meta.fields qset = super(SimpleHitManager, self).get_query_set() qset = qset.filter(hits__site=settings.SITE_ID) return qset class SimpleHitBase(models.Model): hits = generic.GenericRelation(SimpleHit) objects = SimpleHitManager() _hits = None def _db_get_hits(self, only=None): if self._hits == None: try: self._hits = self.hits.get(site=settings.SITE_ID) except SimpleHit.DoesNotExist: self._hits = SimpleHit() return self._hits @property def hits_total(self): return self._db_get_hits().hits_total [...] class Meta: abstract = True And I have a model like: class Model(SimpleHitBase): name = models.CharField(max_length=255) url = models.CharField(max_length=255) rss = models.CharField(max_length=255) creation = AutoNowAddDateTimeField() update = AutoNowDateTimeField() So, my problem is this one: when I call Model.objects.all(), I would like to have one request for the SQL (not two). In this case: one for Model in order to have information and one for the hits in order to have the counter (hits_total). This is because I cannot call directly hits.hits_total (due to SITE_ID?). I have tried select_related, but it seems to do not work... Question: - How can I add column automatically like (SELECT hits.hits_total, model.* FROM [...]) to the queryset? - Or use a functional select_related with my models? I want this model could be plugable on all other existing model. Thank you, Best regards.

  • SLRequest return nil before block complete

    - by jaytr0n
    I'm having a little trouble thinking through this and deciding if it's a design flaw on my behalf or if I'm missing a piece that could make this work. Basically I'm using the new SLRequest to make a Twitter API call. After the data is returned, I'd like to put it into an object and return that object: -(AUDSlide *) getFollowerSlide { SLRequest *getRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:[NSString stringWithFormat:@"https://api.twitter.com/1.1/followers/ids.json?user_id=%@", [[self.twitterAccount valueForKey:@"properties"] valueForKey:@"user_id"]]] parameters:nil]; getRequest.account = twitterAccount; AUDSlide *slide = [[AUDSlide alloc] init]; [getRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { if ([urlResponse statusCode] == 200) { NSError *jsonError = nil; NSDictionary *list = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:&jsonError]; NSLog(@"Number of Followers: %u", [[list objectForKey:@"ids"] count]); slide.title = @"Followers"; slide.number = [NSString stringWithFormat:@"%u",[[list objectForKey:@"ids"] count]]; } else{ slide.title = @"Error"; slide.number = [NSString stringWithFormat: @"E%u", [urlResponse statusCode]]; } }]; return slide; } Of course the slide is returned before the call is complete and returns a nil object. So I'm not sure if I should try to force this into a synchronous request (that seems like it could be a bad idea) or rethink the design. Does anyone have any advice?

  • How can I get sessions to work if I'm using Google App Engine + Django 1.1?

    - by user341642
    Is there a way for me to get sessions working? I know Django has built in session management, and GAE has some tools for it if you're using their watered down version of Django 0.96, but is there a way to get sessions to work if you're trying to use GAE w/ Django 1.1 (i.e. use_library() call). I assume using a db-backed session doesn't work, and a file system backed one won't work b/c we don't have access to the filesystem if we deploy to the Google production servers. This kinda worked (as in didn't crap out) when I used SessionMiddleware backed by a local-memory backed cache and a non-persistent cache (i.e. setting SESSION_ENGINE to django.contrib.sessions.backends.cache). But the session never seems to persist in this case, no matter how I set the timeouts. A new session key is generated on every page reload. Maybe this is b/c the GAE assumes complete statelessness with each request and blows away my local cache? Apologies in advance, I'm pretty new to Python. Any suggestions would be greatly appreciated.

  • How do I get a reference to a rootViewController to a sub-view?

    - by Andy
    An answer posted for one of my previous questions brings up another question; I am calling a new view controller, "RuleBuilder," from my rootViewController. The rootViewController holds a reference to a contacts array. How do I get a reference to that array into the RuleBuilder? I tried adding UITableViewController *rootViewController; ... @property (nonatomic, retain) UITableViewController *rootViewController; to RuleBuilder.h, and then @synthesize rootViewController; in RuleBuilder.m. When I instantiate and push the RuleBuilder from within rootViewController, I do this: ruleBuilder.rootViewController = self; But when I try this [rootViewController.contacts addObject:newContact]; from within RuleBuilder, I get a compiler error to the effect of "request for 'contacts' in something not a struct" (or very similar; I haven't implemented this exact snippet of code, but I tried an identical approach not an hour ago for a couple of different references that I never was able to get working). Thanks, again, for your help.

  • Need for J2me source code

    - by tikamchandrakar
    For J2me It strikes me as odd that you need an extra "api key" and so on. But actually, what I really want is NOT create an extra facebook application that needs to be registered on Facebook. I don't want to create any extra configuration effords necessary for the user of my application to undergo. All my user should need is his well-known login data for facebook. Everything else should be completely transparent to him. So, I thought maybe would u can do the login process, creating a request to the REST server via http. I know this would provide me with an XML. I hope that the this API will somehow automatically transform that XML into an intuitive object model that represents the facebook user data of the respective user. So, I would expect something like userData = new FacebookData(new FacebookConnection("user_name", "password")). Done. If you get, what I mean. No api key. No secret key. Just the well-known login data. Practically, the equivalent to thunderbird webmail, which allows you to access your MSN hotmail account via Thunderbird. Thunderbird webmail will automatically converts the htmls obtained from a hotmail browser login into the data structure usually passed on to a mail client. Hope you get what I mean. I was expecting the equilalent for the your API.

  • How can I close the output stream after a jsp has been included.

    - by stu
    I have a webpage that makes an ajax call to get some data. That data takes a long time to calculate, so what I did was the first ajax server call returns "loading..." and then the thread goes on to calculate the data and store it in a cache. meanwhile the client javascript checks back every few seconds with another ajax call to see if the cache has been loaded yet. Here's my problem, and it might not be a problem. After the initial ajax to the server call, I do a ...getServletContext().getRequestDispatcher(jsppath).include(request, response); then I use that thread to do the calculations. I don't mind tying up the webserver thread with this, but I want the browser to get the response and not wait for the server to close the socket. I can't tell if the server is closing the socket after the include, but I'm guessing it's not. So how can I forcibly close the stream after I've written out my response, before starting my long calculations? I tried o = response.getOutputStream(); o.close(); but I get an illegal state exception saying that the output stream has already been gotten (presumably by the jsp I'm including) So my qestions: 1) is the webserver closing the socket (I'm guessing not, because you could always include another jsp) 2) if it is as I assume not closing the socket, how do I do that?

  • Implementing search functionality with multiple optional parameters against database table.

    - by quarkX
    Hello, I would like to check if there is a preferred design pattern for implementing search functionality with multiple optional parameters against database table where the access to the database should be only via stored procedures. The targeted platform is .Net with SQL 2005, 2008 backend, but I think this is pretty generic problem. For example, we have customer table and we want to provide search functionality to the UI for different parameters, like customer Type, customer State, customer Zip, etc., and all of them are optional and can be selected in any combinations. In other words, the user can search by customerType only or by customerType, customerZIp or any other possible combinations. There are several available design approaches, but all of them have some disadvantages and I would like to ask if there is a preferred design among them or if there is another approach. Generate sql where clause sql statement dynamically in the business tier, based on the search request from the UI, and pass it to a stored procedure as parameter. Something like @Where = ‘where CustomerZip = 111111’ Inside the stored procedure generate dynamic sql statement and execute it with sp_executesql. Disadvantage: dynamic sql, sql injection Implement a stored procedure with multiple input parameters, representing the search fields from the UI, and use the following construction for selecting the records only for the requested fields in the where statement. WHERE (CustomerType = @CustomerType OR @CustomerType is null ) AND (CustomerZip = @CustomerZip OR @CustomerZip is null ) AND ………………………………………… Disadvantage: possible performance issue for the sql. 3.Implement separate stored procedure for each search parameter combinations. Disadvantage: The number of stored procedures will increase rapidly with the increase of the search parameters, repeated code.

  • C socket and openssl (RSA)

    - by giozh
    there's something strange in my client/server socket using RSA. If i test it on localhost, everithing goes fine, but if i put client on a pc and server on othe pc, something gone wrong. Client after call connect, call a method for public keys exchange with server. This part of code works fine. After this, client send a request to server: strcpy(send_pack->op, "help\n"); RSA_public_encrypt(strlen(send_pack->op), send_pack->op, encrypted_send->op, rsa_server, padding); rw_value = write(server, encrypted_send, sizeof (encrypted_pack)); if (rw_value == -1) { stampa_errore(write_error); close(server); exit(1); } if (rw_value == 0) { stampa_errore(no_response); close(server); exit(1); } printf("---Help send, waiting for response\n"); set_alarm(); rw_value = read(server, encrypted_receive, sizeof (encrypted_pack)); alarm(0); if (rw_value == -1) { stampa_errore(read_error); exit(1); } if (rw_value == 0) { stampa_errore(no_response); close(server); exit(1); } RSA_private_decrypt(RSA_size(rsa), encrypted_receive->message, receive_pack->message, rsa, padding); printf("%s\n", receive_pack->message); return; } but when server try to decrypt the receive message on server side, the "help" string doesn't appear. This happen only on the net, on localhost the same code works fine... EDIT: typedef struct pack1 { unsigned char user[encrypted_size]; unsigned char password[encrypted_size]; unsigned char op[encrypted_size]; unsigned char obj[encrypted_size]; unsigned char message[encrypted_size]; int id; }encrypted_pack; encrypted_size is 512, and padding used is RSA_PKCS1_PADDING

  • How can I secure my $_GETs in PHP?

    - by ggfan
    My profile.php displays all the user's postings,comments,pictures. If the user wants to delete, it sends the posting's id to the remove.php so it's like remove.php?action=removeposting&posting_id=2. If they want to remove a picture, it's remove.php?action=removepicture&picture_id=1. Using the get data, I do a query to the database to display the info they want to delete and if they want to delete it, they click "yes". So the data is deleted via $POST NOT $GET to prevent cross-site request forgery. My question is how do I make sure the GETs are not some javascript code, sql injection that will mess me up. here is my remove.php //how do I make $action safe? //should I use mysqli_real_escape_string? //use strip_tags()? $action=trim($_GET['action']); if (($action != 'removeposting') && ($action != 'removefriend') && ($action != 'removecomment')) { echo "please don't change the action. go back and refresh"; header("Location: index.php"); exit(); } if ($action == 'removeposting') { //get the info and display it in a form. if user clicks "yes", deletes } if ($action =='removepicture') { //remove pic } I know I can't be 100% safe, but what are some common defenses I can use. EDIT Do this to prevent xss $action=trim($_GET['action']); htmlspecialchars(strip_tags($action)); Then when I am 'recalling' the data back via POST, I would use $posting_id = mysqli_real_escape_string($dbc, trim($_POST['posting_id']));

  • Storing data in XML or MongoDB

    - by user766473
    Here is my usecase. 1.Have some data, which I am storing now in the xml files. The data that I am storing is not persistent i.e I would be deleting the user data once the user logs out. 2.My server communicates with the client using the XML requests and responses. So initially we decided, since we are sending the XML as response, lets store it in XML so that conversion from database to XML format time is saved. 3.Client will request for XML based on some filter conditions. So will have to use XQUERY. 4.Maximum of 100 entries will be there in an XML, atleast as of now. Now I would like to hear some advice on whether I should use XML or mongodb. My Concerns : 1. How good is it to store temporary data in mongodb and delete/take backup once done with session 2. Conversion from mongodb json format to XML. 3. Handling the changes in the schema design. Cant use any other DB than mongodb. As some persistent operation or still done on mongodb. Thanks in advance.

  • Elegent methods for caching search results from RESTful service?

    - by Paul
    I have a RESTful web service which I access from the browser using JavaScript. As an example, say that this web service returns a list of all the Message resources assigned to me when I send a GET request to /messages/me. For performance reasons, I'd like to cache this response so that I don't have to re-fetch it every time I visit my Manage Messages web page. The cached response would expire after 5 minutes. If a Message resource is created "behind my back", say by the system admin, it's possible that I won't know about it for up to 5 minutes, until the cached search response expires and is re-fetched. This is acceptable, because it creates no confusion for me. However if I create a new Message resource which I know should be part of the search response, it becomes confusing when it doesn't appear on my Manage Messages page immediately. In general, when I knowingly create/delete/update a resource that invalidates a cached search response, I need that cached response to be expired/flushed immediately. The core problem which I can't figure out: I see no simple way of connecting the task of creating/deleting/updating a resource with the task of expiring the appropriate cached responses. In this example it seems simple, I could manually expire the cached search response whenever I create/delete/update a(ny) Message resource. But in a more complex system, keeping track of which search responses to expire under what circumstances will get clumsy quickly. If someone could suggest a simple solution or some clarifying thoughts, I'd appreciate it.

  • Sending a file to an API - C#

    - by alex
    I'm trying to use an API which sends a fax. I have a PHP example below: (I will be using C# however) <?php //This is example code to send a FAX from the command line using the Simwood API //It is illustrative only and should not be used without the addition of error checking etc. $ch = curl_init("http://url-to-api-endpoint"); $fax_variables=array( 'user'=> 'test', 'password'=> 'test', 'sendat' => '2050-01-01 01:00', 'priority'=> 10, 'output'=> 'json', 'to[0]' => '44123456789', 'to[1]' => '44123456780', 'file[0]'=>'@/tmp/myfirstfile.pdf', 'file[1]' => '@/tmp/mysecondfile.pdf' ); print_r($fax_variables); curl_setopt ($ch, CURLOPT_POST, 1); curl_setopt ($ch, CURLOPT_POSTFIELDS, $fax_variables); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $result=curl_exec ($ch); $info = curl_getinfo($ch); $result['http_code']; curl_close ($ch); print_r($result); ?> My question is - in the C# world, how would I achieve the same result? Do i need to build a post request? Ideally, i was trying to do this using REST - and constructing a URL, and using HttpWebRequest (GET) to call the API

  • How to store arbitrary data for some HTML tags

    - by nickf
    I'm making a page which has some interaction provided by javascript. Just as an example: links which send an AJAX request to get the content of articles and then display that data in a div. Obviously in this example, I need each link to store an extra bit of information: the id of the article. The way I've been handling it in case was to put that information in the href link this: <a class="article" href="#5"> I then use jQuery to find the a.article elements and attach the appropriate event handler. (don't get too hung up on the usability or semantics here, it's just an example) Anyway, this method works, but it smells a bit, and isn't extensible at all (what happens if the click function has more than one parameter? what if some of those parameters are optional?) The immediately obvious answer was to use attributes on the element. I mean, that's what they're for, right? (Kind of). <a articleid="5" href="link/for/non-js-users.html"> In my recent question I asked if this method was valid, and it turns out that short of defining my own DTD (I don't), then no, it's not valid or reliable. A common response was to put the data into the class attribute (though that might have been because of my poorly-chosen example), but to me, this smells even more. Yes it's technically valid, but it's not a great solution. Another method I'd used in the past was to actually generate some JS and insert it into the page in a <script> tag, creating a struct which would associate with the object. var myData = { link0 : { articleId : 5, target : '#showMessage' // etc... }, link1 : { articleId : 13 } }; <a href="..." id="link0"> But this can be a real pain in butt to maintain and is generally just very messy. So, to get to the question, how do you store arbitrary pieces of information for HTML tags?

  • Page specific CSS or a single css file when developing a mobile (webkit) based site?

    - by Mike
    I am working on a mobile site for webkit browsers. I have been trying to find information on using multiple style sheets versus a single css file. There is a lot of information on this topic, but it not a lot of information pertaining to mobile browsers. My site will have a bunch of pages that while have page specific css. For a non-mobile site, it seems like generally people say that a single file will be faster, but that multiple files are easier to develop. However, on a mobile site is that still the case? If you put everything in one file, that will get cached after load, but that will make the first load slower. If you had page specific files, the first page would get loaded quicker, but every other page would then take a hit while making the page specific css http request. Does anyone have any thoughts on this? It sounds like they are saying one file is better as long as its under 1 MB (which my files def will)? http://www.yuiblog.com/blog/2010/07/12/mobile-browser-cache-limits-revisited/
