My source code is not working
public async Task<ActionResult> AdjustPrice(string id)
{
var filter = new BsonDocument("_id",id);
return View(await Context.Rentals().Find(filter).FirstOrDefaultAsync());
}
It's working now.
public async Task<ActionResult> AdjustPrice(string id)
{
var filter = Builders<Rentals>.Filter.Eq("Id",id);
return View(await Context.Rentals().Find(filter).FirstOrDefaultAsync());
}
I have a Place data_object in the service side which contains a navigation property Roads:
public class Place : EntityData
{
...
public List<Road> Roads { get; set; }
}
And now on the client side, I want to get a Place object using its id, but the navigation property Roads just won't load. Is there any parameter or attribute I can add to make it work?
My code for it:
var roadList = await App.MobileService.GetTable<Place>()
.LookupAsync(placeId);
Since loading navigation properties in EF requires a JOIN operation in the database (which is expensive), by default they are not loaded, as you noticed. If you want them to be loaded, you need to request that from the client, by sending the $expand=<propertyName> query string parameter.
There are two ways of implementing this: in the server and in the client. If you want to do that in the server, you can implement an action filter which will modify the client request and add that query string parameter. You can do that by using the filter below:
[AttributeUsage(AttributeTargets.Method, AllowMultiple = true)]
class ExpandPropertyAttribute : ActionFilterAttribute
{
string propertyName;
public ExpandPropertyAttribute(string propertyName)
{
this.propertyName = propertyName;
}
public override void OnActionExecuting(HttpActionContext actionContext)
{
base.OnActionExecuting(actionContext);
var uriBuilder = new UriBuilder(actionContext.Request.RequestUri);
var queryParams = uriBuilder.Query.TrimStart('?').Split(new[] { '&' }, StringSplitOptions.RemoveEmptyEntries).ToList();
int expandIndex = -1;
for (var i = 0; i < queryParams.Count; i++)
{
if (queryParams[i].StartsWith("$expand", StringComparison.Ordinal))
{
expandIndex = i;
break;
}
}
if (expandIndex < 0)
{
queryParams.Add("$expand=" + this.propertyName);
}
else
{
queryParams[expandIndex] = queryParams[expandIndex] + "," + propertyName;
}
uriBuilder.Query = string.Join("&", queryParams);
actionContext.Request.RequestUri = uriBuilder.Uri;
}
}
And then you can decorate your method with that attribute:
[ExpandProperty("Roads")]
public SingleItem<Place> GetPlace(string id) {
return base.Lookup(id);
}
Another way to implement this is to change the client-side code to send that header. Currently the overload of LookupAsync (and all other CRUD operations) that takes additional query string parameters cannot be used to add the $expand parameter (or any other $-* parameter), so you need to use a handler for that. For example, this is one such a handler:
class MyExpandPropertyHandler : DelegatingHandler
{
string tableName
string propertyName;
public MyExpandPropertyHandler(string tableName, string propertyName)
{
this.tableName = tableName;
this.propertyName = propertyName;
}
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
if (request.Method.Method == HttpMethod.Get.Method &&
request.RequestUri.PathAndQuery.StartsWith("/tables/" + tableName, StringComparison.OrdinalIgnoreCase))
{
UriBuilder builder = new UriBuilder(request.RequestUri);
string query = builder.Query;
if (!query.Contains("$expand"))
{
if (string.IsNullOrEmpty(query))
{
query = "";
}
else
{
query = query + "&";
}
query = query + "$expand=" + propertyName;
builder.Query = query.TrimStart('?');
request.RequestUri = builder.Uri;
}
}
return await base.SendAsync(request, cancellationToken);
return result;
}
}
And you'd use the handler by creating a new instance of MobileServiceClient:
var expandedClient = new MobileServiceClient(
App.MobileService.ApplicationUrl,
App.MobileService.ApplicationKey,
new MyExpandPropertyHandler("Place", "Roads"));
var roadList = await App.MobileService.GetTable<Place>()
.LookupAsync(placeId);
I want to add repeatable properties to the Jenkins plugin I'm developing, and created a test plugin to make make sure I was using them correctly. My plugin seems to work fine, I can add as many properties as I want when I originally edit the config, and it saves and builds. However, when I try to edit the config a second time, the config screen shows the loading overlay endlessly. If I scroll down, I can see the properties I saved earlier are still there, but I can't edit anything.
My class looks like this:
public class RepeatableTest extends Builder {
private List<Prop> property = new ArrayList<Prop>();
#DataBoundConstructor
public RepeatableTest(List<Prop> property) {
this.property = property;
}
public List<Prop> getProperty() {
return property;
}
#Override
public boolean perform(AbstractBuild build, Launcher launcher, BuildListener listener) throws IOException {
listener.getLogger().println(property.get(0).name);
listener.getLogger().println(property.size());
return true;
}
#Override
public DescriptorImpl getDescriptor() {
return (DescriptorImpl)super.getDescriptor();
}
public static class Prop extends AbstractDescribableImpl<Prop> {
public String name;
public String getName(){
return name;
}
#DataBoundConstructor
public Prop(String name) {
this.name = name;
}
#Extension
public static class DescriptorImpl extends Descriptor<Prop> {
#Override
public String getDisplayName() {
return "";
}
}
}
#Extension // This indicates to Jenkins that this is an implementation of an extension point.
public static final class DescriptorImpl extends BuildStepDescriptor<Builder> {
private String phpLoc;
public DescriptorImpl() {
load();
}
public boolean isApplicable(Class<? extends AbstractProject> aClass) {
// Indicates that this builder can be used with all kinds of project types
return true;
}
public String getDisplayName() {
return "Repeatable Test";
}
#Override
public boolean configure(StaplerRequest req, JSONObject formData) throws FormException {
phpLoc = formData.getString("phpLoc");
save();
return super.configure(req,formData);
}
public String getPhpLoc() {
return phpLoc;
}
}
}
My config.groovy looks like this:
package uitestplugin.uitest.RepeatableTest;
import lib.JenkinsTagLib
import lib.FormTagLib
def f = namespace(lib.FormTagLib)
t=namespace(JenkinsTagLib.class)
f.form{
f.entry(title:"Properties"){
f.repeatableProperty(field:"property")
}
}
and my prop/config.groovy looks like this:
package uitestplugin.uitest.RepeatableTest.Prop;
def f = namespace(lib.FormTagLib)
f.entry(title:"Name", field:"name") {
f.textbox()
}
The config.xml:

Any ideas as to what could cause this? I based a lot of the code from the ui-samples plugin (https://wiki.jenkins-ci.org/display/JENKINS/UI+Samples+Plugin).
EDIT: The current status of this is, well, I still haven't figured it out. I've done more research and tried tons of different examples, but the farthest I ever get is what I described above. It almost seems like you can't use repeatable through groovy. Anyways, I have one more piece of information to add. Using the web developer toolbar for Firefox, I can see that there is a Javascript error on the page. The error is:

I hope this is enough information to solve the problem. Any suggestions (even if they aren't complete answers) are really appreciated.
While not an exact answer, I did find a way to get this working. For some reason, putting the repeatableProperty in an advanced block stopped the javascript error from happening, so everything loaded fine.
So, my config.groovy for RepeatableTest looked like this:
package uitestplugin.uitest.RepeatableTest;
f = namespace(lib.FormTagLib)
f.advanced{
f.entry(title:"Properties"){
f.repeatableProperty(field:"property", minimum:"1"){
}
}
}
My config.groovy for Prop1 looked like this:
package uitestplugin.uitest.Prop1;
def f = namespace(lib.FormTagLib)
f.entry(title:"Name",field:"name") {
f.textbox()
}
f.entry {
div(align:"left") {
input(type:"button",value:"Delete",class:"repeatable-delete")
}
}
My prop 1 looked like this:
public class Prop1 extends AbstractDescribableImpl<Prop1> {
private final String name;
public String getName(){
return name;
}
#DataBoundConstructor
public Prop1( String name) {
this.name = name;
}
#Extension
public static class DescriptorImpl extends Descriptor<Prop1> {
#Override
public String getDisplayName() {
return "";
}
}
}
And my RepeatableTest.java looked like this:
public class RepeatableTest extends Builder {
private final List<Prop1> property;
// Fields in config.jelly must match the parameter names in the "DataBoundConstructor"
#DataBoundConstructor
public RepeatableTest(List<Prop1> property) {
this.property = property;
}
public List<Prop1> getProperty() {
return property;
}
#Override
public boolean perform(AbstractBuild build, Launcher launcher, BuildListener listener) throws IOException {
//Doesn't matter
}
#Override
public DescriptorImpl getDescriptor() {
return (DescriptorImpl)super.getDescriptor();
}
#Extension // This indicates to Jenkins that this is an implementation of an extension point.
public static final class DescriptorImpl extends BuildStepDescriptor<Builder> {
private String phpLoc;
public DescriptorImpl() {
load();
}
public boolean isApplicable(Class<? extends AbstractProject> aClass) {
// Indicates that this builder can be used with all kinds of project types
return true;
}
public String getDisplayName() {
return "Repeatable Test";
}
#Override
public boolean configure(StaplerRequest req, JSONObject formData) throws FormException {
phpLoc = formData.getString("phpLoc");
save();
return super.configure(req,formData);
}
public String getPhpLoc() {
return phpLoc;
}
}
}
I am performing some model validation via a model validator attached to the model at class level. If I find an error I need to be able to attach that error to the relevant field in the view so that it can be shown clearly to the user.
However simply passing in memberNames to the ValidationResult doesn't do anything. Instead what I have found is that I need to re-validate in the controller in order to then populate the ModelState object.
Here is the code:
public class CompletedMilestoneInCorrectOrderAttribute : ValidationAttribute
{
private const string DefaultErrorMessage = "Milestones cannot be completed out of sequence";
public CompletedMilestoneInCorrectOrderAttribute()
: base(DefaultErrorMessage)
{
}
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
var model = (RevisionEditViewModel)validationContext.ObjectInstance;
var previousCompleted = true;
var loop = 0;
var members = new List<string>();
foreach (var rm in model.RevisionMilestones)
{
if (rm.Completed && !previousCompleted)
{
members.Add("revisionMilestones[" + loop + "].ExpectedCompletionDate");
members.Add("revisionMilestones[" + loop + "].Completed");
}
if (!rm.NotApplicable)
{
previousCompleted = rm.Completed;
}
loop++;
}
if (members.Any())
{
return new ValidationResult(DefaultErrorMessage, members);
}
return null;
}
}
And in the controller
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(RevisionEditViewModel model)
{
//without this code the error never gets attached to the correct field in the view
var validationContext = new ValidationContext(model, null, null);
var validationResults = new List<ValidationResult>();
Validator.TryValidateObject(model, validationContext, validationResults);
foreach (var validationResult in validationResults)
{
foreach (var memberName in validationResult.MemberNames)
{
ModelState.AddModelError(memberName, validationResult.ErrorMessage);
}
}
if (ModelState.IsValid)
{
*snip*
}
else
{
*snip*
}
}
Anyone know what is going on? How can I correct it so the messy code in the controller is no longer needed?
Cheers Mike
I am using async method in my Windows 8 development. but it is not updating the UI until it finishes executing full method.
here is my code.
below method calls when user presses refresh button on screen.
public async override void ExceuteRefresh()
{
IsBusy = true; //This is bounded to my UI to show progress bar, but its not updating to UI
foreach (var category in CategoryObservableColl)
{
CheckforOnlineUpdatesAsync(category, true);
}
}
private async void CheckforOnlineUpdatesAsync(Category category, bool isReFresh)
{
var feed = await _dataService.GetOnlineRssFeedAsync(category.RssFeedLink.URL);
var newsCategory = _dataService.GetCategoryFromFeed(feed, true, category.RssFeedLink);
if (newsCategory != null)
{
isRefreshCount +=1;
}
if(isRefreshCount ==9)
{
IsBusy = false;
}
}
IsBusy has implemented InotifyPropertyChanged.
Any help would be greatly appreciated. tried following approach.
public override async void ExceuteRefresh()
{
await Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () => IsBusy = true);
_reloadCategories = false;
_refreshLinkCount = 0;
try
{
foreach (var category in CategoryObservableColl)
{
_refreshLinkCount += 1;
await CheckforOnlineUpdatesAsync(category, true);
}
}
catch (Exception ex)
{
MainPage.ShowMessage("Something Went wrong!. " + ex.Message);
}
}
Also made following method return type as task.
private async Task CheckforOnlineUpdatesAsync(Category category, bool isReFresh)
{
}
Thanks in advance
Try this
Change async void CheckforOnlineUpdatesAsync(...) to async Task CheckforOnlineUpdatesAsync(...)
Change method call to await CheckforOnlineUpdatesAsync(category, true);
Change public async override void ExceuteRefresh() to public async override Task ExceuteRefresh()
Replace IsBusy = false; to below given code. You need to use UI thread to update the UI.
await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () => IsBusy = false);
