I have a product entity and it has an images field that store the images names from the product but the images names depends of a part_number field that is unique, so if the user make a mistake in the part number and he wants to edit it then I also have to change the images names
I tried this but it does not works:
// class ProductsAdmin extends Admin
public function preUpdate($product) {
$old_product = $this->getSubject();
if ($old_product->getPartNumber() != $product->getPartNumber)
{
// change file names
}
$this->saveFile($product);
}
How I get the original row in preUpdate() function?
According to the topic taken from the official SonataAdmin google forum:
https://groups.google.com/forum/#!topic/sonata-devs/0zML6N13i3U
you need to make use of the class UnitOfWork:
http://www.doctrine-project.org/api/orm/2.3/class-Doctrine.ORM.UnitOfWork.html
Do this way:
public function preUpdate($object)
{
$em = $this->getModelManager()->getEntityManager($this->getClass());
$original = $em->getUnitOfWork()->getOriginalDocumentData($object);
}
Thus you get an array of values of your database entity.
E.g: to get access to the value password of your entity do:
$password = $original['password'];
That's all.
Enjoy :)
If you just do a doctrine query in the preUpdate function to get the product from the database you'll have the old object. Then do the comparison and you're good to go.

Good day!
In my Orchard, I have several content types all with my custom part attached. This part defines to what users this content is available. For each logged user there is external service, which defines what content user can or cannot access. Now I need access restriction to apply everywhere where orchard display content lists, this includes results by specific tag from a tag cloud, or results listed from Taxonomy term. I seems can’t find any good way to do it except modifying TaxonomyServices code as well as TagCloud services, to join also my part and filter by it. Is this indeed the only way to do it or there are other solutions? I would like to avoid doing changes to built-in modules if possible but cannot find other way.
Thanks in advance.
I'm currently bumbling around with the same issue. One way I'm currently looking at is to hook into the content manager.
[OrchardSuppressDependency("Orchard.ContentManagement.DefaultContentManager")]
public class ModContentManager : DefaultContentManager, IContentManager
{
//private readonly Lazy<IShapeFactory> _shapeFactory;
private readonly IModAuthContext _modAuthContext;
public ModContentManager(IComponentContext context,
IRepository<ContentTypeRecord> contentTypeRepository,
IRepository<ContentItemRecord> contentItemRepository,
IRepository<ContentItemVersionRecord> contentItemVersionRepository,
IContentDefinitionManager contentDefinitionManager,
ICacheManager cacheManager,
Func<IContentManagerSession> contentManagerSession,
Lazy<IContentDisplay> contentDisplay,
Lazy<ISessionLocator> sessionLocator,
Lazy<IEnumerable<IContentHandler>> handlers,
Lazy<IEnumerable<IIdentityResolverSelector>> identityResolverSelectors,
Lazy<IEnumerable<ISqlStatementProvider>> sqlStatementProviders,
ShellSettings shellSettings,
ISignals signals,
//Lazy<IShapeFactory> shapeFactory,
IModAuthContext modAuthContext)
: base(context,
contentTypeRepository,
contentItemRepository,
contentItemVersionRepository,
contentDefinitionManager,
cacheManager,
contentManagerSession,
contentDisplay,
sessionLocator,
handlers,
identityResolverSelectors,
sqlStatementProviders,
shellSettings,
signals) {
//_shapeFactory = shapeFactory;
_modAuthContext = modAuthContext;
}
public new dynamic BuildDisplay(IContent content, string displayType = "", string groupId = "") {
// So you could do something like...
// var myPart = content.As<MyAuthoPart>();
// if(!myPart.IsUserAuthorized)...
// then display something else or display nothing (I think returning null works for this but
//don't quote me on that. Can always return a random empty shape)
// else return base.BuildDisplay(content, displayType, groupId);
// ever want to display a shape based on the name...
//dynamic shapes = _shapeFactory.Value;
}
}
}
Could also hook into the IAuthorizationServiceEventHandler, which is activated before in the main ItemController and do a check to see if you are rendering a projection or taxonomy list set a value to tell your content manager to perform checks else just let them through. Might help :)
Using Grails (or hibernate), I was wanting to know if there is a specific design pattern or method we should be using when implementing a SEARCH of our domain.
For example, on my website, I want to be able to filter(or search) by multiple properties in the domain.
EG: For I have a page which displays a list of HOTELS. When I submit a search form, or if a user clicks "filter by name='blah'", when I enter the controller I get the following:
Domain
String name
String location
Controller
if(params.name && params.reference) {
// Find name/reference
} else if(params.name) {
// Find name
} else if(params.reference) {
// Find reference
} else {
// Find all
}
As you can understand, if there are more properties in the domain to search/filter, the longer the controller gets.
Any help. Please note, I do not want to use the 'searchable' plugin, as this is too complex for my needs.
I would embed these in a named query in the Domain class itself. For example:
Class Hotel {
String name
String city
String country
boolean isNice
static namedQueries = {
customSearch { p ->
if (p?.name) eq('name', p.name)
if (p?.city) eq('name', p.city)
if (p?.country) eq('name', p.country)
if (p?.isNice != null) eq('isNice', p.isNice)
}
}
}
Then later in a controller somewhere ...
def results = Hotel.customSearch(params)
Of course this is a very simple example, but you can expand on it using the same named query or even adding others and chaining them together.
I'm doin a simple query linq to retrieve a label from an optionSet. Looks like the formatted value for the option set is missing. Someone knows why is not getting generated?
Best Regards
Sorry for the unclear post. I discovered the problem, and the reason of the missing key as formattedvalue.
The issue is with the way you retrieve the property. With this query:
var invoiceDetails = from d in xrmService.InvoiceSet
where d.InvoiceId.Value.Equals(invId)
select new
{
name = d.Name,
paymenttermscode = d.PaymentTermsCode
}
I was retrieving the correct int value for the option set, but what i needed was only the text. I changed the query this way:
var invoiceDetails = from d in xrmService.InvoiceSet
where d.InvoiceId.Value.Equals(invId)
select new
{
name = d.Name,
paymenttermscode = d.FormattedValues["paymenttermscode"]
}
In this case I had an error stating that the key was not present. After many attempts, i tried to pass both the key value and the option set text, and that attempt worked just fine.
var invoiceDetails = from d in xrmService.InvoiceSet
where d.InvoiceId.Value.Equals(invId)
select new
{
name = d.Name,
paymenttermscode = d.PaymentTermsCode,
paymenttermscodeValue = d.FormattedValues["paymenttermscode"]
}
My guess is that to retrieve the correct text associated to that option set, in that specific entity, you need to retrieve the int value too.
I hope this will be helpful.
Best Regards
You're question is rather confusing for a couple reasons. I'm going to assume that what you mean when you say you're trying to "retrieve a label from an OptionSet" is that you're attempting to get the Text Value of a particular OptionSetValue and you're not querying the OptionSetMetadata directly to retrieve the actual LocalizedLabels text value. I'm also assuming "formatted value for the option set is missing" is referring to the FormattedValues collection. If these assumptions are correct, I refer you to this: CRM 2011 - Retrieving FormattedValues from joined entity
The option set metadata has to be queried.
Here is an extension method that I wrote:
public static class OrganizationServiceHelper
{
public static string GetOptionSetLabel(this IOrganizationService service, string optionSetName, int optionSetValue)
{
RetrieveOptionSetRequest retrieve = new RetrieveOptionSetRequest
{
Name = optionSetName
};
try
{
RetrieveOptionSetResponse response = (RetrieveOptionSetResponse)service.Execute(retrieve);
OptionSetMetadata metaData = (OptionSetMetadata)response.OptionSetMetadata;
return metaData.Options
.Where(o => o.Value == optionSetValue)
.Select(o => o.Label.UserLocalizedLabel.Label)
.FirstOrDefault();
}
catch { }
return null;
}
}
RetrieveOptionSetRequest and RetrieveOptionSetResponse are on Microsoft.Xrm.Sdk.Messages.
Call it like this:
string label = service.GetOptionSetLabel("wim_continent", 102730000);
If you are going to be querying the same option set multiple times, I recommend that you write a method that returns the OptionSetMetadata instead of the label; then query the OptionSetMetadata locally. Calling the above extension method multiple times will result in the same query being executed over and over.
I am trying to add fields to com.liferay.portal.model.User, an extra attribute using Expando. Can someone explain to me how this method is adding a field because docs don't have much description.
private void addUserCustomAttribute(long companyId, ExpandoTable userExpandoTable, String attributeName, int type) throws PortalException, SystemException {
ExpandoColumnLocalServiceUtil.getColumn(userExpandoTable.getTableId(), attributeName); //should be addColumn(long tableId, String name, int type) ???
} //and where can find type description couse i have very specific type, Map(String,Object) couse in ExpandoColumnConstants didn't see it
I have taken this from Liferay Expando Wiki's Adding User Custom Attributes.
When should I call this all? Where to put this in my project? What change is required or everything needs to be changed to call it.
Some good tutorial will be nice because it's hard to find something from 0 to end, always found only some part with no explanation.
The question is not very clear. But if you simply want to add a custom attribute for your User then you can refer to my answer here and reproduced for your reference:
Custom field for the user-entity can be created through:
Control Panel -> Portal -> Custom Fields -> User.
And programmatically can be created as follows:
user.getExpandoBridge().addAttribute("yourCustomFieldKey");
Then set the value as:
user.getExpandoBridge().setAttribute("yourCustomFieldKey", "valueForCustomField");
If your custom field is already present you can check like this:
if (user.getExpandoBridge().hasAttribute("yourCustomFieldKey")) { ... };
The data is stored in tables prefixed with "EXPANDO":
EXPANDOCOLUMN: stores the custom field key and other settings
(contains the tableId refrences)
EXPANDODATA: stores the custom field value for the key (contains the
columnId and tableId refrences)
EXPANDOTABLE: stores for which liferay entity (user) are you adding
the custom field
EXPANDOROW: stores linking information between a user and its values
(contains tableId and userId refrences)
Hope this helps.
If your custom field is multivalue, you can use this:
String customVal = "yourCustomFieldValue";
user.getExpandoBridge().setAttribute("yourCustomFieldKey", new String[] {customVal }, false);
The last parameter set to "false" avoids permission check.
What is the best way to pass the model variables to layout in Grails? Specifically, I'm using Spring security plugin which has User class. I also have Contact class that looks like this:
class Contact {
String realname
String company
String mobile
String fix
String email
User user
...
What are the options for getting the currently logged in person's company in my layout (main.gsp)?
To add to the above answer, you could alternatively set a session variable for the user when you login in whatever controller method gets called.
You can also just set a session variable for the company in the controller method:
session.company = Contact.findByUser(session.user)?.company
or from the example above
session.company = Contact.findByUser(SecurityContextHolder.context.authentication?.principal)?.company
And in your main.gsp, something like:
<span id="companyName">${session.company}</span>
Do you mean that you need to pass this model for every page, automatically, instead of manual passing it at render at each of controllers? You can use filters there:
def filters = {
all(controller: '*', action: '*') {
before = {
request.setAttribute('loggedInPerson', SecurityContextHolder.context.authentication?.principal)
//Notice, that there is used original Authentication, from Spring Security
//If you need you can load your Contact object there, or something
}
after = {
}
afterView = {
}
}
}
and use loggedInPerson at your gsp:
Hello ${loggedInPerson.username}!
Btw, there is also Spring Security tags, that can help you without using your own filter, like:
Hello <sec:loggedInUserInfo field="username"/>!
If you want to add a certain object to the model, you can also use the "interceptors" provided by grails. To add a certain variable to a particular controller, you can use something like this.
def afterInterceptor = {model, modelAndView->
model.loggedInUser = getLoggedInUser() // retrieve your user details here
}
And you can retrieve loggedInUser in the main.gsp layout as ${loggedInUser}.
If you need to get these details in multiple controllers, you can create a BaseController and keep the afterInterceptor in this BaseController. All controllers which need the reference to the logged in user in their corresponding views should extend the BaseController.
