I have created an admin module and I'd like the items in the list view, to be able to 'sortable'
I've been looking at the following tutorial http://www.symfony-project.org/cookbook/1_2/en/sortable which seems to shed some light.
The problem is, I'd like the 'move up', 'move down' features in a a partial.
So, I don't want to create a listSuccess.php page, but I then don't have access to the $items object in the executeList() action.
Any ideas how I'd achieve this?
Thanks
Well, you don't need $items, you need only $item->getId()
Create a partial for a field, and inside that partial you will have access to current object being displayed.
You will also need to create _list_footer/_list_header to put Javascript code in.

I'm still learning Laravel and I'm working on a small project to help me understand better. In the project, I am in need of a global array, so that I may display it or its attributes on every view rendered. sort of on a notification bar, so that each page the user visits, he/she can see the number of notifications (which have been fetched in the background and are stored in the array).
I have done some research, and realized that I have to fetch and compile the array in a view composer I think. But everywhere I go, I cant seem to understand how to make a view composer.
I need to fetch the relevant rows from the database table, and make the resulting array available to each view rendered (I'm thinking attaching it somehow to my layouts/default.blade.php file.). Please help, any and all advice is greatly appreciated:)
You can now inject services on your view
More info here: https://laracasts.com/series/whats-new-in-laravel-5-1/episodes/2
You have to use Sub-Views of laravel blade. I guess your functionality is like a sidebar or like a top bar which will be rendered at every page.
//Your Controller pass data
class YOUR_CONTROLLER extends Controller {
public function index()
{
$data = YOUR_DATA;
return view('YOUR_VIEW_FILE', get_defined_vars());
}
}
//In Your View File
#extends('LAYOUTS_FILE')
#section('YOUR_SECTION')
#include('YOUR_SUB_VIEW_FOR_NOTIFICATION')//You need not pass any data passed all data will be available to this sub view.
#endsection
In your sub view
//Do what ever you want looping logic rendering HTML etc.
//In your layout file just yield or render the section that's it
#yield('YOUR_SECTION')

I am trying to create posts with comments with CodeIgniter and I am trying to add voting for the comments with + and -.
But my problem is not actually this functionallity but more exactly creating the link and the method in controller/model for this.
I understand that there is some kind of link to methods.
If I have something like this:
public function like() {
echo 'Test Function';
}
and when I create link like this one sitename.com/posts/first-post/like theoritecally I will see blank page with "Test Function" text (and of course if I write proper routing rule but I cannor for now).
I can see a blank page with this working echo 'Test Function', but does this mean I have to load every methods and views for the entire page if I want to display the entire webpage with all the elements? I think that I mistake something very serious here but I don't know what.
The example with the "Create news" tutorial in ellislab.com didnt help me. They show something similar I think with /create/ section in the URL and create() methods.
If I have many links with functionallities do I have to add new routing rules for all of them? I really tried to search in Google and everywhere but I didnt find anything related.
Sorry for this lame question.
You need to use Ajax call and on callback you have to increase or decrease the count. For creating a link , once page is loading render the data and provided the default link like
for + http://<site.com>/<controller>/like?totalLike=<36>
for - http://<site.com>/<controller>/unlike?totalunLike=<3>
Once user will click + link then by using Ajax, call the controller method link/unlike and increase or decrease the count and repopulate the link again with fresh counter.
Hope it will resolve your problem.
I have:
1.) What should I type in this.control() for getting the reference to the grid panel?
My plan is, when user double clicks one row, new tab is created. I already have code for creating new tabs but I just need to get reference to the grid panel.
Something like this:
'viewport > westpanel > accordion > gridpanel': {
doubleclick: function...
}
2.) Let's say that I gave an ID to the grid panel. How can I get reference in this.control using .get method?
3.) How can I be sure that I've got the right reference? Can I console.log() - it or something like that?
I would know how to do this without MVC but here I need help. :)
Thank you! :)
It is quite easy once you understand how to use it. First you should read the API about the ComponentQuery cause that is what is used within the control.
this depends on your components. You so can go by the xtype 'panel > grid': {itemdblclick:this.yourCallback}
the recommend way if you can't define a really unique path by xtypes '#myID': {itemdblclick:this.yourCallback} using defined refs within the control is not possible in the currently release, as far as I know.
Use Id's instead of just xtypes '#myID > grid': {itemdblclick:this.yourCallback} or define additional params '#myID > grid[customProp=identString]': {itemdblclick:this.yourCallback}
I know how to use Zend_Acl to allow certain resources to certain usergroups but how do i use it to allow only specific parts of the page to be shown? For example
I have a button to delete a post via AJAX on the page but i only want to show the button to Admins only. I can use Zend_Acl to block access to the controller post/delete but i can't use it to block the button from showing.
// in controller
$this->view->allow_delete_post = $acl->isAllowed($role, 'delete_post');
.
// in template
<? if ($this->allow_delete_post): ?>[button html]<? endif; ?>
Would that not do it?
You can also write a custom static ACL class which you can then call directly from within your view script.
Since ACL is normally handled at plugin level it means that if your visitor is seeing the view then ACL has already allowed the resource, therefor inside your view you can now do something like this...
if(My_Custom_Acl::getIsAllowed('some_resource', 'delete_post_action'){
I did not specify the role name in the custom getIsAllowed() method, because at this point ACL is already suppose to know the user's Identity and the Role.
Hope this helps
Although Christof gave a good solution, an alternative is to split the views. Although this starts to violate DRY, when you have about 200 different admin things/controls, it's getting heavy in the view - thus splitting the view with $this->render('view') and $this->render('edit') for permissions from the controller is sometimes easier. Then only the edit view script has the edit links. But again, it's DRY, so not optimal, but an alternative. I guess you have to weigh it up, which one is more DRY, repeating the ACL check or the stuff in 2 views...
Sorry about the question title, but I couldn't find a more appropriate way to phrase this.
I am currently building a CakePHP powered website and I'm not quite sure how to approach the following issue. The website looks something like the follwing mockup:
.
The greyed out areas are part of the layout, because their content does not change between views. In the sidebar, I have a collection of ads who are linked to several models. I need controller logic to determine the picture associated with an ad. Also, the ad list needs to be dynamic. Where should I put the logic for building the sidebar?
I've thought about:
putting the logic into the AppController (beforeFilter / afterFilter) - the problem is I can't use the controller logic I need (the other controllers inherit from AppController, I'm not sure how to use them there).
making a component - is it okay to build components that rely on controllers?
replicating the sidebar code in all controllers that render views - this seems kind of stupid to me.
What is the Cake way for this?
Update
After some reading and experimenting, I've gotten to refactoring most of it.
I obtained the best performance by moving the logic for building my ads in the model (eliminating the component that retrieved the pictures) and not using requestAction. It's almost three times faster and the code looks much better.
I've done something similar for data-driven navigation. I put my logic in AppController::beforeRender and haven't had any problems. I'm not sure I understand your concern related to controller inheritance. I retrieve my menus via:
$menus = $this->NavMenuItem->groupByMenu();
$this->set( compact( 'menus' ) );
I then created an element that renders the menu. It's executed by the layout via:
<?php echo $this->element( 'navigation', array( 'id' => 'secondary', 'menu' => $menus['SECONDARY'] ) ) ?>
If that doesn't help, maybe you can further explain your issue with controller inheritance in a comment.
I guess the answer is requestAction in case the results are cachable:
http://book.cakephp.org/view/434/requestAction
It can be done in this way:
Create an element that will help in layout of the Ad Block
Create one or more controller that will generate the data required for rendering of the block
Use requestAction for getting the data out of the models and into the element.
Check the cake book, there is an example of an element where data from Post Model is used to display top/latest 5 posts. Your requirement, I feel, is very similar to it.
Alex,
you're getting a SQL error because the build() function has to be in the Sidebar model, not controller. Also, you don't necessarily need to use $user = array('Sidebar'); you could calling Sidebar in all of your models with this:
$Sidebar = ClassRegistry::init('Sidebar'); and then $Sidebar->find();, $Sidebar->build(); etc.
Or, if you only need to call the build() function from the Sidebar model, you could do this:
$sidebar = ClassRegistry::init('Sidebar')->build();
$this->set('sidebar', $sidebar);
Cheers.
