I cant find Doctrine_Pager in Doctrine2 and really need a way to page my query results. Is there a way to use some alternative pager (Pear, Zend)? Please post some example code as well if solution is available. Google didnt helped me, so hope folks will :)

I wrote this extension for Doctrine2 that contains a powerful pager:
http://github.com/beberlei/DoctrineExtensions

In Doctrine 2.2, there is a Paginator helper class: http://docs.doctrine-project.org/en/latest/tutorials/pagination.html
Very easy to use :)
use Doctrine\ORM\Tools\Pagination\Paginator;
$dql = "SELECT p, c FROM BlogPost p JOIN p.comments c";
//build the query for the page you want to display
$query = $entityManager->createQuery($dql)
->setFirstResult(0)
->setMaxResults(10);
$paginator = new Paginator($query, $fetchJoinCollection = true);
$c = count($paginator); //automatically makes another query and returns the total number of elements.
//iterating over the paginator iterates over the current page
foreach ($paginator as $post) {
echo $post->getHeadline() . "\n";
}

PagerFanta, as mentioned by Maksim, comes recommended. However, there is also one other pagination bundle that should at least be mentioned: http://symfony2bundles.org/knplabs/KnpPaginatorBundle
Unlike PagerFanta, KnpPaginatorBundle currently requires the zend paginator package as a dependency.

Just as a note though, Query#setMaxResults / Query#setFirstResult covers most of the basic needs for paging.

There is a good 3rd one solution: https://github.com/whiteoctober/Pagerfanta
I found it very useful

MY Question without code so pls bear with me :)
Now in Laravel, you use for links of our app the slug to arrange the links of app. and youtube uses some letters and numbers I don't know what it is for a video! like i0b2ejl7tXM
So what the difference in SEO if we use the unique code like youtube and we use the slug which is the name of the post?
From what I've taken from this article and from my experience, of course it has a difference. The difference, a good URL will increase your post ranks in search engine. But, please keep in mind that SEO isn't just it. Please take a look at this good diagram.
You can use a function to generate and decode strings for your routes.
Routes:
Route::get(/'{code}', 'YourController#yourMethod');
Controller:
public function yourMethod(Request $request, $code)
{
$decodedValue = decodingFunction($code)
...
}

Please consider the below code
a=b.select_lists[0]
a.select("Agent")
In the aforementioned code, the first line is taking so much time, So Can anyone tell me Is there any way to store value of "a" object for further use without getting from b.select_lists[0]? Or Is there anyway can we directly get the value of 'a'?
The code which I am trying to write for the select list follows below
<select class="ng-valid ng-dirty" style="" ng-change="selectionsAgentType(AgentType)" ng-model="AgentType"> <select class="ng-valid ng-dirty" ng-change="AgentCategorySelected(agentoptions)" ng-model="agentoptions">
If option with text: 'Agent' is unique on this page.
If you need just simulate select
b.option(:text, 'Agent').select
Also, if you need value of this option
a = b.option(:text, 'Agent').value
Else,
b.select_lists.first.option(:text, 'Agent').select
a = b.select_lists.first.option(:text, 'Agent').value

I'm on visual studio and I have trouble doing some boolean on Visual Basic for a Combo Box Boolean. I am using Visual Studio btw. I tried to add the following:
if ClientBox.ValueMember() = "Agentleader1 (Leader)" Then
But it wouldn't work.
My program is a basic Contact-Us form for a person to fill out. A field (the combo-box field, called: clientbox) is a combo-box to where you can select which member of the whole group you want to send the contact-form to. Which is a problem. I'm very sorry I can't give a sample of the code. And btw, I just started C++ please don't give complex answers and maybe add a few annotations so I can understand. Please comment this question if I have not explained enough about my program! BTW, please no C# answers.
I found a solution to my problem, if anybody is wondering here it is, sorry for my amateur-ness! This actually kinda is a better answer than anything I could have come up with (except the fact that I found this answer by myself:
if ComboBox.SelectedItem().Equals("any choice of one of the items") = True Then
'execute command!
The above was the syntax, I got an example of my code below:
if ClientBox.SelectedItem().Equals("Agentleader1 (Leader)") = True Then
TEA = "****" 'That's my email!
Hope this helped to anybody that couldn't figure out how to find whether a specified item that is selected in a certain combo-box is selected!
is that exactly how it is written in your code? the single '=' is an assignment operator... you need '=='

Ruby detect if a column value has changed [closed]

So I have this line:
if self.company_changed?
And it works fine but this detects if the company has changed on the object. I need to know if the database value has changed and not if the value in memory has changed. So I tried this:
if :company_changed?
This seems to work in debug mode when I only execute the one line. If I let it run, it fails in testing on an infinite loop.
My question is what can be used in ruby to check to see if the column value has actually changed.
I'm pretty sure you're actually talking about ActiveRecord. In which case, you'd need to re-fetch the record to see if the value has changed in the database.
self.class.find(self.id).company != self.company
A general purpose method for this might be something like:
def attr_changed_in_db?(attr)
self.class.find(self.id).attributes[attr] != self.attributes[attr]
end
There is an excellent screencast on this by the great Ryan Bates.

I have a website where I have used joomla with virtuemart. I have added a custom field Where field type is Cart Variant. But problem is I don't want to display the price in the drop down select option. You can see it from this screen short (http://i.stack.imgur.com/yCx3a.jpg) or (http://awesomescreenshot.com/011ih9ue8)
I want to remove the red mark item. Anyone can help me please.
After a long try I got the solution. I am using joomla 2.5.7 & virtuemart v2.0.12. Just follow this:
Go to:
administrator/components/com_virtuemart/models/customfields.php & find the following line it may be line number 871:
$productCustom->text = $productCustom->custom_value . ' ' . $price;
Delete . $price & that's all :)
Please be more specific, this issue is related to virtuemart, the best way to get an answer is to ask it on official site forum.virtuemart.com.
What version of joomla and virtuemart are you using?
On Back-end in virtuemart configuration you can set not display price, have you tried this?
If this won't work, you will probably need to make template override, usually located in components/com_virtuemart/views/productdetails/tmpl/default_showprices.php
Without more info I'm not able to answer your question better.
