  • How to give the appearance of a button with a <div>?

    - by user246114
    Hi, I'm looking at the buttons used on twitter's home page, specifically the big orange 'signup' button. I see it is defined like this: <p id="signup-btn"> <a id="signup_submit" href="/signup"> <span>Sign Up</span> </a> </p> are they just using css to give the orange button appearance (which may just be a jpg), and also using css to specify the roll-over appearance (another jpg), and finally a third state for mouse-click (another jpg) to give the impression of a real clickable button? If that's how it works, what should I look for to do the same thing? In my case I just want to make a button I guess, like: <div class='mybutton'>Hello!</div> .mybutton { bgcolor: red; bgcolor-mouseover: yellow; bgcolor-mousedown: green; } yeah something like that would be great, Thanks

  • How to get the app a Django model is from?

    - by e-satis
    I have a model with a generic relation: TrackedItem --- genericrelation ---> any model I would like to be able to generically get, from the initial model, the tracked item. I should be able to do it on any model without modifying it. To do that I need to get the content type and the object id. Getting the object id is easy since I have the model instance, but getting the content type is not: ContentType.object.filter requires the model (which is just content_object.__class__.__name__) and the app_label. I have no idea of how to get in a reliable way the app in which a model is. For now I do app = content_object.__module__.split(".")[0], but it doesn't work with django contrib apps.

  • A better understanding of the relations beetween database tables

    - by Nistor Alexandru
    Hi I am trying to get a better understanding of relational databases and there is something that I keep bumping into and don't understand.Let's take this two tables: In this case Login.ID is the primary key with auto_increment set and Profile.ID_LOGIN is the Foreign KEY.When a user is created and it's username and password is stored in the login database does the ID coresponding to the curesnt username and password get automaticly added into ID_LOGIN or do I have to create an SQL statement to do this? If I have to create a SQL statement how should I aproach adding the ID_LOGIN to make sure I am adding it corectly?

  • looking for RTF template system with simple DSL

    - by 01
    Is there any framework that fills up rtf document with data? The idea is to make business people/testers change the document in MsWord and than generate reports from that. The problem is with tables, Id need to create some special DSL for handling tables and showing hidding text/page parts. Id rather not do that and use some existing solution. I tried to search for something, but I only found frameworks that can produce rtf output from xml input and i want to use rtf as input and output.

  • How do I return the numeric value from a database query in PHP?

    - by Luke
    Hello, I am looking to retreive a numerical value from the database function adminLevel() { $q = "SELECT userlevel FROM ".TBL_USERS." WHERE id = '$_SESSION[id]'"; return mysql_query($q, $this->connection); } This is the SQL. I then wrote the following php/html: <?php $q = $database->adminLevel(); if ($q > 7) { ?> <a href="newleague.php">Create a new league</a> <? } ?> The problem I have is that the userlevel returned isn't affecting the if statement. It is always displayed. How do i get it to test the value of userlevel is greater than 7? Thanks

  • backbonejs remove anomaly concept

    - by user1537158
    I was building a small app for adding and deleting li from ul using Backbonejs.One of the SO members cymen helped me code it, using that i tailored the code a little.currently if i add one element and delete , it works , but the second time i add an element (to ul) and go to delete it , i get Uncaught TypeError: Cannot call method 'remove' of undefined Pasting my code here , HTML : <input type="text" id="name"> <button id="add">Add</button> <ul id="mylist"></ul> JS: $(function(){ var myCollection = Backbone.Collection.extend(); var myView = Backbone.View.extend({ el:$('body'), tagName:'li', initialize : function(e){ this.collection.bind("add",this.render,this); this.collection.bind("remove",this.render,this); }, events:{ 'click #add' : 'addfoo' }, addfoo : function(){ var myname= $('#name').val(); $('#name').val(''); this.collection.add({name:myname}); }, render : function(){ $('#mylist').empty(); this.collection.each(function(model){ console.log("myView"); var remove = new myRemoveView({model:model}); remove.render(); }); } }); var myRemoveView = Backbone.View.extend({ el:$('body'), events:{ 'click .button':'removeFoo' }, removeFoo : function(){ console.log("here"); this.model.collection.remove(this.model); }, render : function(){ console.log("second view"); $('#mylist').append('<li>'+this.model.get('name') + "<button class='button'>"+"delete"+"</button></li>"); return; } }); var view = new myView({collection: new myCollection()}); }); Two things i did not understand : i) in the removeFoo function , we write this.model.collection.remove(this.model) shouldnt this have been this.collection.model.remove , something of that sort ? ii) i add a li to ul , then i delete it , when i add another li (appending to ul works perfect) but this time when i go to delete it throws me the above error : Uncaught TypeError :cannot call method 'remove' of undefined can you please help me figure out these 2 doubts in my code , btw SO member cymen's code works like a charm only my tailored code (above) is giving me errors. SO member cymen's code : JS Fiddle for his code Thank you

  • Fluent Nhibernate mapping related items

    - by Josh
    I am trying to relate 2 items. I have a table that is simply an Id field, and then 2 columns for the Item Id's to relate. I want it to be a 2 way relationship - that is, if the items appear twice in the table, I only want one relationship connection back. So, here's my item: public class Item { public virtual Guid ItemId {get; set;} public virtual string Name {get; set;} public virtual IList<Item> RelatedItems {get; set;} } The table for relating the items looks like this: CREATE TABLE RelatedItems ( RelatedItemId uniqueidentifier NOT NULL, ItemId uniqueidentifier NOT NULL, RelatedId uniqueidentifier NOT NULL, CONSTRAINT PK_RelatedItems PRIMARY KEY CLUSTERED (RelatedItemId) ) What is the best way to map this connection?

  • Am I underestimating MySQL ?

    - by user281434
    Hi I'm about to implement a feature on my website that recommends content to users based on the content they already have in their library (a la Last.fm). A single table holds all the records of the content they have added, so a row might look something like: -------------------- | userid | content | -------------------- | 28 | a | -------------------- When I want to recommend some content for a user, I use a query to get all the user id's that have content a added in their library. Then, out of those user id's, I make another query that finds the next most common content among those users (fx. 'b'), and show that to the user. My problem is when I'm thinking about the big picture here. Say that eventually my site will hold something like 500.000 rows in the table, will this make the MySQL response very slow or am I underestimating MySQL here?

  • Join using combined conditions on one join table

    - by Nathan Wienert
    I have join a table joining songs to genres. The table has a 'source' column that's used to identify where the genre was found. Genres are found from blogs, artists, tags, and posts. So, songs | song_genre | genres id | song_id, source, genre_id | id What I want to build is a song SELECT query that works something like this, given I already have a genre_id: IF exists song_genre with source='artist' AND a song_genre with source='blog' OR exists song_genre with source='artist' AND a song_genre with source='post' OR exists song_genre with source='tag' I'm was going to do it by doing a bunch of joins, but am sure I'm not doing it very well. Using Postgres 9.1.

  • [FLEX] MVC: choosing a view at runtime

    - by Alberto M
    Hi all, I'm quite new to the MVC design-pattern, and I'm translating all of my old code. I want to move to this pattern because I can change my views according to my needs, but I'm finding difficult to do it at runtime. I found an excellent example of MVC, and all that I do is the following: <mx:ViewStack xmlns:mx="http://www.adobe.com/2006/mxml" resizeToContent="true" xmlns:views="MVC.views.*"> <views:HomeView id="Home"/> <views:SecondPage id="SecondPage "/> </mx:ViewStack> what if I wanted to change (whenever the Controller says so) one of the views, for example the SecondPage view? (Hope I made my point clear)

  • Has anyone seen this h:commandLink behavior?

    - by Liggy
    I have a very simple JSF form: <h:form id="simpleSearch"> <h:inputText id="surname" value="#{myBean.surname}" required="true" /> <h:commandLink>Search</h:commandLink> </h:form> When this page is rendered, the anchor that is generated looks like this (for brevity, I stripped out the generated onclick code): Search<a href="#" onclick="..."></a> As you can see, the "Search" is outside the anchor and the anchor body is empty. This is useless to me. I can't use this. Are there any suggestions/references/miracles out there to help me fix/understand what is going on here? Thanks!

  • Uniquely identifying mobile devices over a network for webforms

    - by Eric
    I'm designing a system for mobile devices that can be assigned only to one job at a time. So I need to be able to know which mobile device is being used by accessing it's own unique static IP address or its device ID. I don't want to assign an ID myself for every machine that comes in which is why a static IP would work great. However, in trying to retrieve the client ip address I'm retrieving the wireless router's ip or some other ip which is not the mobile device's ip. I want to store that ip in a table and control which jobs are assigned to it. How can I accomplish this? I've tried the following but I'm getting the wireless ip: var hostEntry = Dns.GetHostEntry(Dns.GetHostName()); var ip = ( from addr in hostEntry.AddressList where addr.AddressFamily.ToString() == "InterNetwork" select addr.ToString() ).FirstOrDefault(); I'd rather not set a cookie if there exists a better alternative. TIA!

  • Reset JPA generated value between tests

    - by Rythmic
    I'm running spring + hibernate + JUnit with springJunit4runner and transactional set to default rollback I'm using in-memory derbydb as Database. Hibernate is used as a JPA Provider and I am successfully testing CRUD kinds of stuff. However, I have a problem with JPA and the behaviour of @GeneratedValue If I run one of my tests in isolation, two entitys are persisted with id 1 and 2. If i run the whole test suite the ids are instead 6 and 7. Spring does rollbacks just fine so there are only these two entitys in the database after addition and of course zero before. But behaviour of @GeneratedValue doesn't allow me to reliable findById unless I would return the Id from the dao.add(Entity e) //method I don't feel like doing that for the sake of testing, or is it a good practise to return the entity that was persisted so I should be doing it anyway?

  • Joining two select queries and ordering results

    - by user1
    Basically I'm just unsure as to why this query is failing to execute: (SELECT replies.reply_post, replies.reply_content, replies.reply_date AS d, members.username FROM (replies) AS a INNER JOIN members ON replies.reply_by = members.id) UNION (SELECT posts.post_id, posts.post_title, posts.post_date AS d, members.username FROM (posts) as b WHERE posts.post_set = 0 INNER JOIN members ON posts.post_by = members.id) ORDER BY d DESC LIMIT 5 I'm getting this error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'a INNER JOIN members ON replies.re' at line 2 All I'm trying to do is select the 5 most recent rows (dates) from these two tables. I've tried Join, union etc and I've seen numerous queries where people have put another query after the FROM statement and that just makes no logical sense to me as to how that works? Am I safe to say that you can join the same table from two different but joined queries? Or am I taking completely the wrong approach, because frankly I can't seem see how this query is failing despite reading the error message. (The two queries on there own work fine)

  • doctrine default values and relations

    - by Skirmantas
    Concept: Lets say we have table Properties with columns id and name (lets say with some predefined values: "Good" "Better" "Best"). Another table Users has column property_id with many to one relation on Properties (property_id = id). Users has default value on property_id, lets say 1 which means "Good". We might have another table analogue to Users however with default property, lets say "Better". What I need is ability to change default value for Users or other tables in administrator's panel. In mysql I can set default value for column like this: ALTER TABLE <Table> CHANGE <Column> DEFAULT <NEW_DEFAULT_VALUE> I can retrieve default value: SELECT DEFAULT(<Column>) FROM <Table> LIMIT 1 Is it possible to achieve this concept with Doctrine? What I actually need is such method in my table class: class UserTable extend Doctrine_Table { /* ... */ getDefaultProperty() { } setDefaultProperty($value) { /* $value can be either integer or Doctrine_Record */ } }

  • Trying to understand the Zend_Auth OpenId

    - by Will Olbrys
    I'm using a slightly modified version of the Zend_Auth_OpenId classes to get openid logins from google apps. The results are very positive, as I seem to be getting successful results from Google. I cannot get successful results passed to Zend_Auth, though. For example, Zend_Auth_Adapter_OpenId on line 241: if (!$consumer->login($id, $this->_returnTo, $this->_root, $this->_extensions, $this->_response)) { return new Zend_Auth_Result( Zend_Auth_Result::FAILURE, $id, array("Authentication failed", $consumer->getError())); } The consumer calls login() which in turn calls the private method _checkId() in Zend_OpenId_Consumer. _checkId() always ends in redirecting to the openid server. How is this ever supposed to return a valid Zend_Auth_Result object? I'm pretty close to giving up and trying to implement another OpenId library, but I'm so close to just making this work. I must be missing something so obvious! Maybe I don't understand how openid works exactly, but if someone could help me understand I would really appreciate it.
