I am using Struts validation by extending action to ActionSupport.
When I try to put special character on the UI, then default actionErrors are adding up in the collections like Illegal characters were detected in the input, please remove them and try again.
Then I need to remove that default validation coming up on UI. I have no idea to deal with it.
My code is like this:
void validate(){
if (locationBean.getReasonTypeId() == 0)
{
addActionError("Error in reason");
}
if (ValidationHelper.checkRequiredField(locationBean.getName()))
{
addActionError("Error in Location name");
}
}
My validation action class is like this:
public class ValidationErrorJSONAction extends ActionSupport
{
private JSONObject jsonObject;
#SuppressWarnings("unchecked")
public String execute() throws Exception
{
jsonObject = new JSONObject();
jsonObject.put("actionErrors", new JSONArray(getActionErrors()));
jsonObject.put("fieldErrors",new JSONObject(getFieldErrors()));
TokenHelperJSON.appendToken(jsonObject);
return SUCCESS;
}
Hope it will help you to understand the problem.

The is driving me nuts. Im trying to do a "simple" record insert and I can only get it to work if I store the context in a variable or create a local context. I tried to keep the context and model object tied together but no luck so far.
public class TransactionDataAccessLayer
{
public cartableContext transactionContext
{
get
{
return new cartableContext();
}
}
}
class TransactionBusinessLayer
{
Cardata newCar = new Cardata();
public void addCar(Cardata cd)
{
try
{
//this works. Storing the context in ctc2 seems to make it work???
TransactionDataAccessLayer tdal = new TransactionDataAccessLayer();
cartableContext ctc2 = tdal.transactionContext;
ctc2.cardata.Add(cd);
ctc2.SaveChanges();
//this does not work
tdal.transactionContext.cardata.Add(cd);
tdal.transactionContext.Entry(cd).State = EntityState.Modified;
tdal.transactionContext.SaveChanges();
}
catch (Exception ex)
{
Console.WriteLine(ex.InnerException);
}
}
}
In C#, properties are basically just fancy methods, designed to make it easier to access private fields. Therefore, returning a new Context in your getter will do just that; return a new one each time it is accessed. To preserve state, you need to contain your context in a private field, like so:
public class TransactionDataAccessLayer
{
private cartableContext _transactionContext;
public cartableContext transactionContext
{
get
{
if (_transactionContext == null)
_transactionContext = new cartableContext();
return _transactionContext;
}
}
}
I am unable to get my custom compoenent to be validated in the dynamic form. I tried many versions but it is not working as expected. For e.g. either the label is not showing in BOLD to indicate the field is mandatory and it aloows to save the form without entering anything in the field. Only when the user enters something in the field and deletes it, then the red icon is displayed to the user that the field is mandatory.I dont know what i am missing. please help. code is below
telnumber = new CustomTelephoneTextItem();
telnumber.setName("tel");
telnumber.setTitle("Tel");
telnumber.setTitle(nerpweb.clientFactory.getMessages().tel());
Below is my Custom TextItem which i am using in the above class
public class CustomTelephoneTextItem extends CanvasItem
{
textField_value = new CustomIntegerItem();
textField_value.setShowTitle(false);
textField_value.setWidth(100);
textField_value.setRequired(true);
form.setItems(textField_value, textField_code);
form.validate();
setWrapTitle(false);
this.setCanvas(form);
First, if you want to item title showin bold, you must call item's setRequired(true).
in your code is telnumber.setRequired(true);
Second, if you want to validate item on form.validate(), you must override validate() function in your item and write validation code in this function.
in your code is call form.validate() in CustomTelephoneTextItem validate() function
Here is the code to be implemented to validate custom component
This code will go in your Custom component which you will implement
#Override
public Object getValue()
{
if (validate() && textField_value.getValue() != null)
return textField_value.getValue();
return null;
}
#Override
public void setRequired(Boolean required) {
super.setRequired(true);
}
#Override
public Boolean validate() {
return super.validate();
}
#Override
public void setValidators(Validator... validators) {
textField_value.setValidators(validators);
}
Then in the class where you will create the custom component you will call the setRequired() method,like so
telnumber.setRequired(true);
I am in the early stages of developing a new module.
Much of it is laid out in terms of the models etc. Also have the migrations all set up and my database now has the tables for my module.
I am encountering the following error when calling ContentManager.New<myPart> and would like some help please.
Error is this:
An unhandled exception has occurred and the request was terminated. Please refresh the page. If the error persists, go back
Specified cast is not valid.
System.InvalidCastException: Specified cast is not valid.
at Orchard.ContentManagement.ContentCreateExtensions.New[T]
(IContentManager manager, String contentType)
The chunk of code that fires the exception is this:
public static T New<T>(this IContentManager manager, string contentType) where T : class, IContent {
var contentItem = manager.New(contentType);
if (contentItem == null)
return null;
var part = contentItem.Get<T>();
if (part == null)
throw new InvalidCastException();
return part;
}
Here are the various parts to my module that are related to the operation i am struggling with:
ContentPart
public class GoogleMapsSettingsPart : ContentPart<GoogleMapsSettingsPartRecord>
{
public string ApiKey {
get { return Record.ApiKey; }
set { Record.ApiKey = value; }
}
}
ContentPartRecord
public class GoogleMapsSettingsPartRecord : ContentPartRecord
{
public virtual string ApiKey { get; set; }
}
Handler
public GoogleMapsSettingsPartHandler(IRepository<GoogleMapsSettingsPartRecord> repository)
{
Filters.Add(StorageFilter.For(repository));
}
Migration for this table
// Settings Table
SchemaBuilder.CreateTable("GoogleMapsSettingsPartRecord", table => table
.ContentPartRecord()
.Column("ApiKey", DbType.String, c => c.WithLength(60))
);
Some of the code from the controller for this model etc
public AdminController(IContentManager contentManager, IShapeFactory shapeFactory, IServiceLocatorService serviceLocatorService, INotifier notifier)
{
_contentManager = contentManager;
_serviceLocatorService = serviceLocatorService;
_notifier = notifier;
Shape = shapeFactory;
T = NullLocalizer.Instance;
}
/// <summary>
/// Display Settings
/// </summary>
/// <returns></returns>
public ActionResult Settings()
{
var settings = _serviceLocatorService.GoogleMapsSettings;
var editor = CreateSettingsEditor(settings);
var model = _services.ContentManager.BuildEditor(settings);
return View((object)model);
}
Finally - the Services where my call throws this exception
private GoogleMapsSettingsPart _settings;
public GoogleMapsSettingsPart GoogleMapsSettings
{
get {
if (_settings == null)
{
_settings = _contentManager.Query<GoogleMapsSettingsPart, GoogleMapsSettingsPartRecord>().List().FirstOrDefault();
if (_settings == null)
{
_settings = _contentManager.New<GoogleMapsSettingsPart>("GoogleMapsSettings");
}
}
return _settings;
}
}
The actual line where the exception happens is _settings = _contentManager.New<GoogleMapsSettingsPart>("GoogleMapsSettings");
I have tried all sorts of stuff in place of "GoogleMapsSettings" though nothing is working.
I'm pretty sure at this point it's something simple, though it's avoiding me..My limited knowledge of Orchard is stumping me
Any help would be appreciated :)
The exception is thrown because your content type does not have the part you specified to get.
_contentManager.New<GoogleMapsSettingsPart>("GoogleMapsSettings");
This method call creates a new content item of type GoogleMapSettings and gets the content item as a GoogleMapsSettingsPart. However, it seems that GoogleMapSettings content type does not have a GoogleMapsSettingsPart. That's why the exception gets thrown here.
var part = contentItem.Get<T>();
if (part == null)
throw new InvalidCastException();
You must either attach the part dynamically to your content type or do it in a migration (or manually in the admin, but that's not a good idea). Your migration should look like this.
this.ContentDefinitionManager.AlterTypeDefinition("GoogleMapsSettings",
alt => alt
.WithPart("GoogleMapsSettingsPart");
Ok, so I fixed it...
My understanding of how Orchard works is still very much in the learning stages.
for this particular operation I didn't want to have a content type in the admin - though not sure why after adding the ContentType it still didn't work...
anyway, adding the lines below to my handler took care of the rest. I believe it's actually creating a temporary type so one isn't needed in the system.
public GoogleMapsSettingsPartHandler(IRepository<GoogleMapsSettingsPartRecord> repository)
{
Filters.Add(new ActivatingFilter<GoogleMapsSettingsPart>("GoogleMapsSettings"));
Filters.Add(StorageFilter.For(repository));
Filters.Add(new TemplateFilterForRecord<GoogleMapsSettingsPartRecord>("GoogleMapsSettings", "Parts/GoogleMapsSettings"));
}
I'v got the same error, but in my case it was everything ok with migration class.
The reason was unlucky merge, which deleted my driver class of my part.
Just look at this code of Activating method of ContentPartDriverCoordinator class. In my case there was no partInfo for my content part and resulted part became ContentPart, so casting throws an exception
var partInfos = _drivers.SelectMany(cpp => cpp.GetPartInfo()).ToList();
foreach (var typePartDefinition in contentTypeDefinition.Parts) {
var partName = typePartDefinition.PartDefinition.Name;
var partInfo = partInfos.FirstOrDefault(pi => pi.PartName == partName);
var part = partInfo != null
? partInfo.Factory(typePartDefinition)
: new ContentPart { TypePartDefinition = typePartDefinition };
context.Builder.Weld(part);
}
I have added a key-value pair in the action result like this:
[HttpPost, Authorize]
public ActionResult ListFacilities(int countryid)
{
...
ModelState.AddModelError("Error","No facilities reported in this country!");
...
}
I have some cumbersome codes like these in a unit test to :
public void ShowFailforFacilities()
{
//bogus data
var facilities = controller.ListFacilities(1) as PartialViewResult;
Assert.AreSame("No facilities reported in this country!",
facilities.ViewData.ModelState["Error"].Errors.FirstOrDefault().ErrorMessage);
}
Of course, it works whenever I have only one error.
I don't like facilities.ViewData.ModelState["Error"].Errors.FirstOrDefault().ErrorMessage.
Is there an easier way for me to fetch the value from that dictionary?
Your FirstOrDefault isn't needed, because you'll get a NullReferenceException when accessing ErrorMessage. You can just use First().
Either way, I couldn't find any built-in solution. What I've done instead is create an extension method:
public static class ExtMethod
{
public static string GetErrorMessageForKey(this ModelStateDictionary dictionary, string key)
{
return dictionary[key].Errors.First().ErrorMessage;
}
}
Which works like this:
ModelState.GetErrorMessageForKey("error");
If you need better exception handling, or support for multiple errors, its easy to extend...
If you want this to be shorter you can create an extension method for the ViewData...
public static class ExtMethod
{
public static string GetModelStateError(this ViewDataDictionary viewData, string key)
{
return viewData.ModelState[key].Errors.First().ErrorMessage;
}
}
and usage:
ViewData.GetModelStateError("error");
Have you tried this?
// Note: In this example, "Error" is the name of your model property.
facilities.ViewData.ModelState["Error"].Value
facilities.ViewData.ModelState["Error"].Error
I'm passing json back up from my view to my controller actions to perform operations. To convert the json being sent in, to a POCO I'm using this Action Filter:
public class ObjectFilter : ActionFilterAttribute {
public Type RootType { get; set; }
public override void OnActionExecuting(ActionExecutingContext filterContext) {
IList<ErrorInfo> errors = new List<ErrorInfo>();
try {
object o = new DataContractJsonSerializer(RootType).ReadObject(filterContext.HttpContext.Request.InputStream);
filterContext.ActionParameters["postdata"] = o;
}
catch (SerializationException ex) {
errors.Add(new ErrorInfo(null, ex.Message));
}
finally {
filterContext.ActionParameters["errors"] = errors.AsEnumerable();
}
}
It's using the DataContractJsonSerializer to map the JSON, over to my object. My Action is then decorated like so:
[ObjectFilter(RootType = typeof(MyObject))]
public JsonResult updateproduct(MyObject postdata, IEnumerable<ErrorInfo> errors) {
// check if errors has any in the collection!
}
So to surmise, what is going on here, if there is a problem serializing the JSON to the type of object (if a string cannot be parsed as a decimal type or similar for eg), it adds the error to a collection and then passes that error up to the view. It can then check if this collection has an errors and report back to the client.
The issue is that I cannot seem to find out which field has caused the problem. Ideally I'd like to pass back to the view and say "THIS FIELD" had a problem. The SerializationException class does not seem to offer this sort of flexibility.
How would the collective SO hivemind consider tackling this problem?
I would just do an ajax form post. It's much easier.

How about this: Json.Net
It reads a JSON string and then Deserialises it to the given POCO object.
string jsonResult = GetJsonStringFromSomeService();
MyPocoObject myobject = JsonConvert.DeserializeObject<MyPocoObject>(jsonResult);
Console.Write("Damn that is easy");
But for the determing where errors occur, I am not too sure.
