I have an app built on top of Silex and I'm using Doctrine as my ORM.
I have a problem where I'm trying to get a clean error for when a user tries to reuse an email, I found the validator UniqueEntity but it seems to be designed for the full stack version of Symfony.
My question is, is this true? I'm going a limb and assuming it as I haven't found anyone who successfully used it outside of Symfony.
My second question is, if I'm not able to use UniqueEntity, whats my next best option? I'm using the Symfony Validator component and would like to use something that's plugged into that to keep it all in the same block of code.
You can use UniqueEntity with Silex.
Here's the service provider package with the Doctrine ManagerRegistry implementation - saxulum/saxulum-doctrine-orm-manager-registry-provider. Also you can find the instructions how to use it with the UniqueEntity validator in README.
But you may want to implement you own UniqueEntity validator.
For example, if you want to validate DTO object (or any non-entity object), because it's not supported by Symfony's UniqueEntity validator (see issue on GitHub).

I use Doctrine DBAL v2.5.0 and I would like to perform a simple update statement. In the documentation it is written that I should use the method executeUpdate() (http://doctrine-dbal.readthedocs.org/en/latest/reference/data-retrieval-and-manipulation.html#executeupdate) for that. But in the source code this method has the annotation #internal. Because of that I am not sure whether this method should be used from non-library code or not. Should I?
It seems that you have to use the executeUpdate() method on the doctrine service and not on the entity manager.
$this->container->get('doctrine.orm.entity_manager')->getConnection()->executeUpdate($query); gives a warning in my IDE that executeUpdate() is #internal.
$this->container->get('doctrine')->getConnection()->executeUpdate($query);
or in a controller $this->getDoctrine()->getConnection()->executeUpdate($query); does not give any warning.
With other words:
You want to call the executeUpdate() method on
\Doctrine\Bundle\DoctrineBundle\Registry class
instead of the
\Doctrine\ORM\EntityManager class
P.D. Maybe I should mention that I am using Doctrine in conjunction with Symfony2.
Previously when I developed ember application I used App as my global object and every class was stored in this big object.
Like this
window.App.MyModel = Em.Object.extend({});
And in the browser console, I was able to do
App.MyModel.create();
So it was really easy for me to access MyModel class.
Now I started experiments with Ember-CLI, I don't have much experience with this kind of tools. I followed the documentations and I created my model Service like this.
var Service = Ember.Object.extend({});
export default Service
But now, how to access Service class from browser console?
Only way I found was:
App.__container__.resolve('model:service')
But I don't like it much. Is there better way? Btw, can you please explain how export works? Or is there some source (documentation, article) where I can study it?
Thanks a lot for response.
If you're aiming to have something available in most places throughout your application you'll typically want to register it on the container.
There are multiple ways to access the container, and you're correct in that the one you found was less than ideal. The running joke is "any time you directly access __container__ we need to add more underscores."
To directly control how things are registered on the container and injected into the container you typically want to use an initializer. Using initializers in ember-cli is super-easy, they're executed for you automatically.
Checking out the documentation you can see that you get access to the application's container as an argument which allows you to manipulate it in a safe manner.
Once you have access to the container you can use register and inject to make content easily available in particular locations. This was introduced here. One note, accessing things inside of the container from outside the context of your app (browser console) will require the usage of App.__container__ and that is the expected use pattern.
And the export you're running into is an ES6 module system construct, it's not Ember-specific. Playing with the ES6 module transpiler can give you a good sense of what goes in and what comes out in "we can do this today" type of JavaScript.
For ember 3.22, application classes can be accessed like so:
Ember.Namespace.NAMESPACES[1]._applicationInstances.values().next().value.lookup('service:state-events')
Note, you may need to modify the index in NAMESPACES[1] to be something other than 1. You can determine which namespace is your application when this returns true:
Ember.Namespace.NAMESPACES[1] instanceof Application
This approach is how ember-inspector accesses ember applications: https://github.com/emberjs/ember-inspector/blob/50db91b7bd26b12098cae774a307208fe0a47d75/ember_debug/main.js#L163-L168
I am currently in the process of writing a custom DataProvider. Using the Intergrate External Data documentation.
I've managed to show the external data in the Sitecore back end. However whenever I try to view the data in the items I created, I am getting an error
Null ids are not allowed. <br> Parameter name: displayName
There seems to be precious little on the subject on how to create a custom DataProvider on the Sitecore Developer Network.
The example on their website seems to only show how to import a SINGLE item into a static database. However I am simply trying to merge some items into the hierarchy and I can't find any useful documentation.
It seems that one of your methods that should return an ID doesn't. It might be GetChildIds and/or GetParentId.
Nick Wesselman wrote a good article about it gathering all the information including an example on the Marketplace. I think that is your best start. You can read it here.
Turns out I needed to include at the very least, the Fields->Section->Template in the GetParent method. To be on the safe side I included the Fields/Sections/Templates into my implementations of
GetChildIDs
GetItemDefinition
GetParentID
It wasn't obvious that this was the case, since I had in fact implemented the GetTemplates method correctly, and I had expected that should be enough.
how can I use the controllers created at
/administrator/components/com_mycom/controllers/*
in
/components/com_mycom/mycom.php
In detail:
I have a »log« controller with an »add« method, and I would like to use this from the frontend. I one is not logged in in the backend the task is not executed and a 500 error rises. So just would like to include the backend controllerpath in the frontend, so that JController::getInstance( 'Mycom' ) still works.
Greetings…
EDIT:
After a long time of searching I could find a more or less undocumented Parameter of the:
JController::getInstance() method, namely the second one: $config = array(). Going through the source code I found out that there is one key of the »config-array« that is of interest, which is: »base_path«.
The call of:
JController:getInstance( 'Mycom, array('base_path' =>JPATH_ADMINISTRATOR.DS.'components'.DS.'com_mycom')' );
always delivers the backend controller and one can use them safely in the frontend, BUT one must take care that then also the views are taken from the backend side of the component. In my case, I just use it to make ajax-calls so it does not matter, but one needs to be careful with using this method when planning to create »frontend views« with »backend controller«.
Greetings…
I had recently a similar problem where I wanted to use the whole CRUD system form back-end also in front-end.
This is the method that worked for me (and I am not saying that this is recommended or best practice):
I've just modeled the folders / file structure from backend. PHP files contained something like:
require_once JPATH_ADMINISTRATOR . '/components/com_mycom/controllers/log.php';
I've been trying to programmatically reproduce the behavior of editing a Content Type's field properties in the SharePoint site management screen and selecting the "Required" radio button with no sucess using the WSS 3.0 web service's Webs.asmx "UpdateContentType" method.
The first difficulty was the issue with the MSDN documentation that said fields should be of a FieldRef type when in fact they need to be of a Field type (reference). Adding fields and deleting fields works fine after the fix, but updating fields seems to not function at all. (It should also be noted that I followed the recommendation on the previous link to use Method="2" for updating fields but it changes nothing, and using Method values other than 1 for adding or other than 3 for deleting also function correctly).
Here's the web service call (slightly modified with strings instead of XmlNode objects for readability):
SharePointWebServices.Webs webService = new SharePointWebServices.Webs();
webService.Url = "http://mysharepointserver/site";
webService.UseDefaultCredentials = true;
webService.UpdateContentType(
#"0x01005A089D9EC8A382458FB1F6C72096D52A",
#"<ContentType />",
#"<Fields />",
#"<Fields><Method ID=""1""><Field Name=""SomeField"" ID=""{8a4803c4-6545-4a7a-804d-237eebff0ce3}"" Required=""TRUE"" Hidden=""FALSE"" ReadOnly=""FALSE"" PITarget="""" PIAttribute="""" PrimaryPIAttribute="""" Aggregation="""" Node="""" /></Method></Fields>",
#"<Fields />");
After the call, the field is still Required="FALSE".
A quick look into the stssoap.dll assembly indicates that the "Required" property is apparently ignored during the update process. Is this normal behavior? If so, what is the recommended method for programmatically changing the "Required" field from client code (not executing on the SharePoint server)?
Any help would be greatly appreciated.
I've investigated this and found the same thing. I also tried adding the attribute Cmd="Update" to the Method element without success. This example of how to use UpdateContentType was helpful too.
I don't believe you will be able to do this with the out-of-the-box SharePoint services. You've verified from looking at stssoap.dll that this doesn't appear to work correctly. Another 'client'-style option is to use RPC methods but none appear to provide functionality for content types at all.
The web services are particularly frustrating because this type of not-so-edge case regularly comes up. It is very rare that I consider using them because of the time wasting involved with their limitations.
Do you have any option of deploying custom code to the server? You could develop this functionality using the object model and wrap it in your own custom web service (there is a walkthrough here) quite easily.
Here is an example adapted from Gabe Wishnie that does what you require:
SPContentType myContentType = myWeb.ContentTypes["myContentType"];
string internalName = myContentType.Fields["fieldToUpdate"].InternalName;
myContentType.FieldLinks[internalName].Required = false;
myContentType.Update(true);
Sorry this isn't more helpful but it's a common story when using the WSS 3.0 / SharePoint 2007 web services.
