  • problems getting HTTPRiot working

    - by bwizzy
    I've got an iphone app where I'm trying to use HTTPRiot to make some API calls to a web app. Problem is I can't see that none of the HTTPRiot delegate methods are being called. I've got a log in all the delegate methods, and I'm also looking at the webserver log. I see that the URL is being hit. //API.h #import <Foundation/Foundation.h> #include <HTTPRiot/HTTPRiot.h> @interface API : HRRestModel { } +(void)runTest; @end //API.m #import "API.h" @implementation API + (void)initialize { NSLog(@"api initialize"); [self setDelegate:self]; [self setBaseURL:[NSURL URLWithString:@"http://localhost:3000/api"]]; [self setBasicAuthWithUsername:@"demo" password:@"123456"]; NSDictionary *params = [NSDictionary dictionaryWithObject:@"1234567" forKey:@"api_key"]; [self setDefaultParams:params]; }//end initialize +(void)runTest { NSLog(@"api run test"); // Would send a request to http://localhost:1234/api/people/1?api_key=1234567 [self getPath:@"/save_diet" withOptions:nil object:nil]; } +(void)restConnection:(NSURLConnection *)connection didReturnResource:(id)resource object:(id)object { NSLog(@"didReturnResource"); } +(void)restConnection:(NSURLConnection *)connection didReceiveResponse:(NSHTTPURLResponse *)response object:(id)object { NSLog(@"didReceiveResponse"); } +(void)restConnection:(NSURLConnection *)connection didReceiveParseError:(NSError *)error responseBody:(NSString *)body object:(id)object { NSLog(@"didReceiveParseError"); } +(void)restConnection:(NSURLConnection *)connection didReceiveError:(NSError *)error response:(NSHTTPURLResponse *)response object:(id)object { NSLog(@"didReceiveError"); } +(void)restConnection:(NSURLConnection *)connection didFailWithError:(NSError *)error object:(id)object { NSLog(@"didFailWithError"); } @end //test code [API runTest]; //log output

  • Basic user authentication with records in AngularFire

    - by ajkochanowicz
    Having spent literally days trying the different, various recommended ways to do this, I've landed on what I think is the most simple and promising. Also thanks to the kind gents from this SO question: Get the index ID of an item in Firebase AngularFire Curent setup Users can log in with email and social networks, so when they create a record, it saves the userId as a sort of foreign key. Good so far. But I want to create a rule so twitter2934392 cannot read facebook63203497's records. Off to the security panel Match the IDs on the backend Unfortunately, the docs are inconsistent with the method from is firebase user id unique per provider (facebook, twitter, password) which suggest appending the social network to the ID. The docs expect you to create a different rule for each of the login method's ids. Why anyone using 1 login method would want to do that is beyond me. (From: https://www.firebase.com/docs/security/rule-expressions/auth.html) So I'll try to match the concatenated auth.provider with auth.id to the record in userId for the respective registry item. According to the API, this should be as easy as In my case using $registry instead of $user of course. { "rules": { ".read": true, ".write": true, "registry": { "$registry": { ".read": "$registry == auth.id" } } } } But that won't work, because (see the first image above), AngularFire sets each record under an index value. In the image above, it's 0. Here's where things get complicated. Also, I can't test anything in the simulator, as I cannot edit {some: 'json'} To even authenticate. The input box rejects any input. My best guess is the following. { "rules": { ".write": true, "registry": { "$registry": { ".read": "data.child('userId').val() == (auth.provider + auth.id)" } } } } Which both throws authentication errors and simultaneously grants full read access to all users. I'm losing my mind. What am I supposed to do here?

  • An html input box isn't being displayed, Firebug says it has style="display: none" but I haven't don

    - by Ankur
    I have placed a form on a page which looks like this: <form id="editClassList" name="editClassList" method="get" action="EditClassList"> <label> <input name="class-to-add" id="class-to-add" size="42" type="text"> </label> <label> <input name="save-class-btn" id="save-class-btn" value="Save Class(es)" type="submit"> </label> </form> But when it get's rendered by a browser it comes out like this: <form id="editClassList" name="editClassList" method="get" action="EditClassList"> <label> <input style="display: none;" name="class-to-add" id="class-to-add" size="42" type="text"> </label> <label> <input name="save-class-btn" id="save-class-btn" value="Save Class(es)" type="submit"> </label> </form> For some reason style="display: none;" is being added, and I cann't understand why. This results in the text box not displaying.

  • Unit Testing Interfaces in Python

    - by Nicholas Mancuso
    I am currently learning python in preperation for a class over the summer and have gotten started by implementing different types of heaps and priority based data structures. I began to write a unit test suite for the project but ran into difficulties into creating a generic unit test that only tests the interface and is oblivious of the actual implementation. I am wondering if it is possible to do something like this.. suite = HeapTestSuite(BinaryHeap()) suite.run() suite = HeapTestSuite(BinomialHeap()) suite.run() What I am currently doing just feels... wrong (multiple inheritance? ACK!).. class TestHeap: def reset_heap(self): self.heap = None def test_insert(self): self.reset_heap() #test that insert doesnt throw an exception... for x in self.inseq: self.heap.insert(x) def test_delete(self): #assert we get the first value we put in self.reset_heap() self.heap.insert(5) self.assertEquals(5, self.heap.delete_min()) #harder test. put in sequence in and check that it comes out right self.reset_heap() for x in self.inseq: self.heap.insert(x) for x in xrange(len(self.inseq)): val = self.heap.delete_min() self.assertEquals(val, x) class BinaryHeapTest(TestHeap, unittest.TestCase): def setUp(self): self.inseq = range(99, -1, -1) self.heap = BinaryHeap() def reset_heap(self): self.heap = BinaryHeap() class BinomialHeapTest(TestHeap, unittest.TestCase): def setUp(self): self.inseq = range(99, -1, -1) self.heap = BinomialHeap() def reset_heap(self): self.heap = BinomialHeap() if __name__ == '__main__': unittest.main()

  • Transparently surround a component with a link in Wicket

    - by Toni Menzel
    I want to be able to add links on certain items in an ListView. If an items is surrounded by the link or not is up to the code, so its not in the normal page markup. Say i have a markup like this: <div class="column" wicket:id="columnRepeater"> <span wicket:id="column"></span> </div> So essentially, while filling the repeater with a ListView i am able to find a custom renderer for the column component. (not my playingfield). What i want is to add a Link/Ajax Link around the column component. I learned using wicket:border lets you surround additional stuff. Now, the border markup looks like this: <wicket:border> <a wicket:id="link"><wicket:body/></a> </wicket:border> Now, i am a bit puzzled what the Border implementation looks like. Anyone there who can suggest a working java part? I have a couple of "work in progress" solutions but none works. Most questions have to do with usage of component ids. Is the border id = column ? Whats the id of the inner (border body) id then?

  • Prevent jQuery Tabs to bind to <ul> elements below the main <ul> element.

    - by Shiki
    Hi, I have this HTML: <div id="mytabs"> <ul id="main-tabs"> <li><a href="">Link</a></li> <li><a href="">Link</a></li> <li class="filter"> <ul id="filter-controls"> <li><a href="">Filter by something</a></li> <li><a href="">Filter by something</a></li> <li><a href="">Filter by something</a></li> </ul> </li> </ul> </div> And I set it to a tabbed control: $('#mytabs').tabs(); My problem is jQuery UI also converts the <li> elements in <ul id="filter-controls"> into tabs. Is there a way to instruct jQuery UI to only set the <li> children of <ul id="main-tabs"> as the tabs? Note: I am currently in no position to change <ul id="filter-controls" into a non-ul element.

  • PHP/mysqli: Inserting IP address with mysqli_stmt_bind_param()

    - by invarbrass
    Hello! I have a database table which contains an unsigned integer field to store the visitor's IP address: `user_ip` INT(10) UNSIGNED DEFAULT NULL, Here's the snippet of PHP code which tries to store the IP address: $ipaddr = $_SERVER['REMOTE_ADDR']; if ($stmt = mysqli_prepare($dbconn, 'INSERT INTO visitors(user_email, user_ip) VALUES (?,?)')) { $remote_ip = "INET_ATON('$ipaddr')"; mysqli_stmt_bind_param($stmt, 'ss', $email, $remote_ip); if (mysqli_stmt_execute($stmt) === FALSE) return FALSE; $rows_affected = mysqli_stmt_affected_rows($stmt); mysqli_stmt_close($stmt); } The INSERT operation succeeds, however the user_ip field contains a null value. I have also tried changing the parameter type in mysqli_stmt_bind_param() (which was set to string in the above example) to integer, i.e. mysqli_bind_param(... 'si',...) - but to no avail. I've also tried using the following bit of code instead of mysql's INET_ATON() SQL function: function IP_ATON($ipaddr) { $trio = intval(substr($ipaddr,0,3)); return ($trio>127) ? ((ip2long($ipaddr) & 0x7FFFFFFF) + 0x80000000) : ip2long($ipaddr); } It still doesn't work - the 'user_ip' field is still set to null. I've tried passing the $ip_addr variable as both integer & string in mysqli_bind_param() - to no avail. It seems the problem lies with the parameterized insert. The following "old-style" code works without any problem: mysqli_query(..., "INSERT INTO visitors(user_email, user_ip) VALUES ('$email',INET_ATON('$ipaddr'))"); What am I doing wrong here? Thanks in advance!

  • How to pass a parameter in a Javascript confirm function?

    - by Miles M.
    I have something like that in my code: <?php foreach($clients as $client): ?> <tr class="tableContent"> <td onclick="location.href='<?php echo site_url('clients/edit/'.$client->id ) ?>'"><?php echo $client->id ?></td> <td><a class='Right btn btn-danger' onClick="ConfirmMessage('client', <?php $client->id ?>,'clients')"> <i class="icon-remove-sign icon-white"></i> </a></td> </tr> <?php endforeach ?> that's actually the view. So when the user click on the delete button (thr one with the btn-danger class) I'd like him to confirm his choice with a javascript confirmation box message. You can find that script in the header <script> function ConfirmMessage(type, id, types) { if (confirm("Are you sure you want to delete this ",type," ?")) { // Clic sur OK document.location.href='<?php echo site_url(); ?>',types,'/delete/',id; } } </script> So here is my question: I would like the $type to be replaced by a paramenter (like client, article, post .. ) that I'll pass to the function. And i would like to get the $client-id parameter as well. I'm bad in javascript and as you already have guess, It is obviously not working at all.

  • HTML form never calls Javascript

    - by user1205577
    I have a set of radio buttons defined in HTML like so: <input type="radio" name="group" id="rad1" value="rad1" onClick="doStuff(this.id)">Option 1<br> <input type="radio" name="group" id="rad2" value="rad2" onClick="doStuff(this.id)">Option 2<br> Just before the </body> tag, I have the following JavaScript behavior defined: <script type="text/javascript"> /*<![CDATA[*/ function doStuff(var id){ alert("Doing stuff!"); } /*]]>*/ </script> When I run the program, the page loads as expected in my browser window and the radio buttons allow me to click them. The doStuff() function, however, is never called (I validated this using breakpoints as well). I also tried the following just to see if inline made the difference, but it seems the JavaScript is never called at all: <script type="text/javascript"> /*<![CDATA[*/ alert("JavaScript called!"); main(); function main(){ var group = document.getElementsByName('group'); for(var i=0; i<group.length; i++){ group[i].onclick = function(){ doStuff(this.id); }; } } /*]]>*/ </script> My question is, is there something special I need to do using HTML and JavaScript in this context? My question is not whether I should be using inline function calls or whether this is your favorite way to write code.

  • Can i make this div fill out the remaining space depending on the the sidebars widths?

    - by Marcus
    i have 4 divs inside of a div like this: <div id="Wrapper"> <div id="CoreSideBar"><!-- a sidebar to the right --> </div> <div id="SystemContent"> <div id="SystemNavigation"><!-- will be some kind of "tabnavigation" in the top of this div --> </div> <div id="PageContent"> </div> <div id="SystemSideBar"> <!-- a sidebar to the left --> </div> </div> </div> I would like the sidebars to have 200px width each and im also going to make it possible to "collapse" the sidebars so you can have more space for the PageContent div if you need it. What do i need to do to make the PageContent div fill out the remaining whitespace between the CoreSideBar and the SystemSidebar? Is this even possible in all browsers?

  • content_tag_for a collection in Rails?

    - by Nick
    I have a Post model. Posts have many Comments. I want to generate a <ul> element for post.comments using content_tag_for. Ideally, it'd produce <ul id="comments_post_7" class="comments"> ... </ul> where 7 is the ID of the Post. The closest I can get uses <% content-tag-for :ul post, :comments do %> which produces <ul id="comments_post_7" class="post"> ... </ul> which is pretty close, except for the class="post". Using :class => :comments in the content_tag_for yields class="post comments", but I just want class="comments". It seems logical that I'd be able to use something like <% content_tag_for :ul post.comments do %> but, sadly, that yields <ul id="array_2181653100" class="array"> ... </ul> I've searched far and wide. I feel like I'm missing some elegant way to do this. Am I? Because, seriously, <ul id="comments_post_<%= post.id %>" class="comments"> is painful.

  • Accessing HTML DOM elements from javascript using `.childNodes`

  • Facebook call back function with timeout

    - by Dirty Bird Design
    So I've been getting my ass kicked pretty good with Facebook's moving target of an API. I need to display some hidden content after a person clicks 'like' on a landing page. I can somewhat get this to work, when the user clicks 'like' the normal fb dialogue appears and then goes away immediately and content is displayed. I have 'achieved' this with the following js. <script> FB.Event.subscribe('edge.create', function(href, widget) { document.getElementById('goodies').style.display = "block"; document.getElementById('fb-content').style.display= "block"; document.getElementById('copy').style.display = "none"; }); </script> I cannot find any documentation about a callback event after someone hits "post to facebook" or after the dialogue closes, only afte they hit like. How would I incorporate a setTimeout function into this to give people some time to fill out the fb dialogue? thanks. If anyone has a better way to do this I'm all ears. This is for a business page and I cannot seem to add an app to get an app ID anymore so the API is pretty useless to me at this point. Also, if the url to be liked is a fb page, the callbacks don't seem to fire. Other code used: <html xmlns:fb="http://ogp.me/ns/fb#"> <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk')); </script> <fb:like href="onlynonfburl.com" send="false" layout="button_count" width="450" show_faces="false" font="arial"></fb:like>

  • Unknown ListView Behavior

    - by st0le
    I'm currently making a SMS Application in Android, the following is a code snippet from Inbox Listactivity, I have requested a cursor from the contentresolver and used a custom adapter to add custom views into the list. Now, in the custom view i've got 2 TextViews (tvFullBody,*tvBody*)... tvFullBody contains the Full SMS Text while tvBody contains a short preview (35 characters) The tvFullBody Visibility is by default set to GONE. My idea is, when the user clicks on a list item, the tvBody should dissappear(GONE) and the tvFullBody should become visible (VISIBLE). On Clicking again, it should revert back to its original state. //isExpanded is a BitSet of the size = no of list items...keeps track of which items are expanded and which are not @Override protected void onListItemClick(ListView l, View v, int position, long id) { if(isExpanded.get(position)) { v.findViewById(R.id.tvFullBody).setVisibility(View.GONE); v.findViewById(R.id.tvBody).setVisibility(View.VISIBLE); }else { v.findViewById(R.id.tvFullBody).setVisibility(View.VISIBLE); v.findViewById(R.id.tvBody).setVisibility(View.GONE); } isExpanded.flip(position); super.onListItemClick(l, v, position, id); } The Code works as it is supposed to :) except for an undesired sideeffect.... Every 10th (or so) List Item also gets "toggled". eg. If i Expand the 1st, then the 11th, 21th list items are also expanded...Although they remain off screen, but on scrolling you get to see the undesired "expansion". By my novice analysis, i'm guessing Listview keeps track of 10 list items that are currently visible, upon scrolling, it "reuses" those same variables, which is causing this problem...(i didn't check the android source code yet.) I'd be gratefull for any suggestion, on how i should tackle this! :) I'm open to alternative methods aswell....Thanks in advance! :)

  • Is it possible to have a mysql table accept a null value for a primary_key column referencing a diff

    - by Dr.Dredel
    I have a table that has a column which holds the id of a row in another table. However, when table A is being populated, table B may or may not have a row ready for table A. My question is, is it possible to have mysql prevent an invalid value from being entered but be ok with a NULL? or does a foreign key necessitate a valid related value? So... what I'm looking for (in pseudo code) is this: Table "person" id | name Table "people" id | group_name | person_id (foreign key id from table person) insert into person (1, 'joe'); insert into people (1, 'foo', 1)//kosher insert into people (1, 'foo', NULL)//also kosher insert into people(1, 'foo', 7)// should fail since there is no id 7 in the person table. The reason I need this is that I'm having a chicken and egg issue where it makes perfect sense for the rows in the people table to be created before hand (in this example, I'm creating the groups and would like them to pre-exist the people who join them). And I realize that THIS example is silly and I would just put the group id in the person table rather than vice-versa, but in my real-world problem that is not workable. Just curious if I need to allow any and all values in order to make this work, or if there's some way to allow for null.

  • A specific data structure

    - by user550413
    Well, this question is a bit specific but I think there is some general idea in it that I can't get it. Lets say I got K servers (which is a constant that I know its size). I have a program that get requests and every request has an id and server id that will handle it. I have n requests - unknown size and can be any number. I need a data structure to support the next operations within the given complexity: GetServer - the function gets the request ID and returns the server id that is supposed to handle this request at the current situation and not necessarily the original server (see below). Complexity: O(log K) at average. KillServer - the function gets as input a server id that should be removed and another server id that all the requests of the removed server should be passed to. Complexity: O(1) at the worst case. -- Place complexity for all the structure is O(K+n) -- The KillServer function made me think using a Union-Find as I can do the union in O(1) as requested but my problem is the first operation. Why it's LogK? Actually, no matter how I "save" the requests if I want to access to any request (lets say it's an AVL tree) so the complexity will be O(log n) at the worst case and said that I can't assume Kn (and probably K Tried thinking about it a couple of hours but I can't find any solution. Known structures that can be used are: B+ tree, AVL tree, skip list, hash table, Union-Find, rank tree and of course all the basics like arrays and such.

    - by bugz
    For some reason when i tested parsing a json string to a dropdownlist it worked doing this var json = [{ "Id": "12345", "WorkUnitId": "SR0001954", "Description": "Test Service Request From Serena", "WorkUnitCategory": "ServiceRequest" }, { "Id": "12355", "WorkUnitId": "WOR001854", "Description": "Test Work Order From Serena", "WorkUnitCategory": "ServiceRequest" }, { "Id": "12365", "WorkUnitId": "DBR001274", "Description": "Test Database Related Service Request From Serena", "WorkUnitCategory": "ServiceRequest"}]; $(json).each(function() { comboboxWorkUnit.append($('<option>').val(this.Id).text(this.WorkUnitId)); }); However when i tryed taking the json from my webservice and placing it into the dropdownlist i get an error saying the dropdownlist doesnt support this metod. $.ajax({ type: "POST", url: "Services/WorkUnitService.asmx/WorkUnit", data: "{'Number' : '" + Number.text() + "','Id': '" + combobox.val() + "','workerType': '" + EmployeeType + "'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(json) { $(json).each(function() { comboboxWorkUnit.append($('<option>').val(this.Id).text(this.WorkUnitId)); }); } }); I also tried which called the webservice method but through an error $.postJSON("Services/WorkUnitService.asmx/WorkUnitsForParAndPhase", "{'parNumber' : '" + parNumber + "','phaseId': '" + combobox.val() + "','workerType': '" + EmployeeType + "'}", function(data) { alert(data.toString()); }); And i tryed this which never called the webservice $.getJSON('Services/WorkUnitService.asmx/WorkUnitsForParAndPhase' + parNumber + '/' + combobox.val() + '/' + EmployeeType, function(myData) { alert(myData.toString()); });

  • Using sortable_element in Rails on a list generated by a find()

    - by Eli B.
    Hey all, I'm trying to use the scriptaculous helper method sortable_element to implement a drag-and-drop sortable list in my Rails application. While the code for the view looks pretty simple, I'm really not quite sure what to write in the controller to update the "position" column. Here's what I've got in my view, "_show_related_pgs.erb": <ul id = "interest_<%=@related_interest.id.to_s%>_siblings_list"> <%= render :partial => "/interests/peer_group_map", :collection => @maps, :as => :related_pg %> </ul> <%= sortable_element("interest_"+@related_interest.id.to_s+"_siblings_list", :url => {:action => :resort_related_pgs}, :handle => "drag" ) %> <br/> And here's the relevant line from the partial, "interests/peer_group_map.erb" <li class = "interest_<%=@related_interest.id.to_s%>_siblings_list" id = "interest_<%=related_pg.interest_id.to_s%>_siblings_list_<%=related_pg.id.to_s%>"> The Scriptaculous UI magic works fine with these, but I am unsure as to how to change the "position" column in the db to reflect this. Should I be passing the collection @maps back to the controller and tell it to iterate through that and increment/decrement the attribute "position" in each? If so, how can I tell which item was moved up, and which down? I couldn't find anything specific using Chrome dev-tools in the generated html. After each reordering, I also need to re-render the collection @maps since the position is being printed out next to the name of each interest (I'm using it as the "handle" specified in my call to sortable_element() above) - though this should be trivial. Any thoughts? Thanks, -e

  • UpdateModelFromDatabaseException when trying to add a table to Entity Framework model

    - by Agent_9191
    I'm running into a weird issue with Entity Framework in .NET 3.5 SP1 within Visual Studio 2008. I created a database with a few tables in SQL Server and then created the associated .edmx Entity Framework model and had no issues. I then created a new table in the database that has a foreign key to an existing table and needed to be added to the .edmx. So I opened the .edmx in Visual Studio and in the models right-clicked and chose "Update Model From Database...". I saw the new table in the "add" tab, so I checked it and clicked finish. However I get an error message with the following text: --------------------------- Microsoft Visual Studio --------------------------- An exception of type 'Microsoft.Data.Entity.Design.Model.Commands.UpdateModelFromDatabaseException' occurred while attempting to update from the database. The exception message is: 'Cannot update from the database. Cannot resolve the Name Target for ScalarProperty 'ID <==> CustomerID'.'. --------------------------- OK --------------------------- For reference, here's the tables seem to be the most pertinent to the error. CustomerPreferences already exists in the .edmx. Diets is the table that was added afterwards and trying to add to the .edmx. CREATE TABLE [dbo].[CustomerPreferences]( [ID] [uniqueidentifier] NOT NULL, [LastUpdatedTime] [datetime] NOT NULL, [LastUpdatedBy] [uniqueidentifier] NOT NULL, PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] CREATE TABLE [dbo].[Diets]( [ID] [uniqueidentifier] NOT NULL, [CustomerID] [uniqueidentifier] NOT NULL, [Description] [nvarchar](50) NOT NULL, [LastUpdatedTime] [datetime] NOT NULL, [LastUpdatedBy] [uniqueidentifier] NOT NULL, PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[Diets] WITH CHECK ADD CONSTRAINT [FK_Diets_CustomerPreferences] FOREIGN KEY([CustomerID]) REFERENCES [dbo].[CustomerPreferences] ([ID]) GO ALTER TABLE [dbo].[Diets] CHECK CONSTRAINT [FK_Diets_CustomerPreferences] GO This seems like a fairly common use case, so I'm not sure where I'm going wrong.
