I am using ListBlobsSegmentedAsync in my C# code to list all the blobs.Is there a way i can separate the images and videos from response of ListBlobsSegmentedAsync ?
Here is an example from this link. You should be able to optimise the code to do a yield return which will return results iteratively and not leave your calling code waiting for all the results to be returned.
public static String WildCardToRegular(String value)
{
return "^" + Regex.Escape(value).Replace("\\*", ".*") + "$";
}
Then, using it with ListBlobsSegmentedAsync:
var blobList = await container.ListBlobsSegmentedAsync(blobFilePath, true, BlobListingDetails.None, 1000, token, null, null);
var items = blobList.Results.Select(x => x as CloudBlockBlob);
// Filter items by search pattern, if specify
if (!string.IsNullOrEmpty(searchPattern))
{
items = items.Select(i =>
{
var filename = Path.GetFileName(i.Name);
if (Regex.IsMatch(filename, WildCardToRegular(searchPattern), RegexOptions.IgnoreCase))
{
return i;
}
return null;
}).ToList();
}

I am trying to achieve a small amount of javascript code that is able to locate a key that contains another key with the most array element occurrences in a string. It's a little hard to explain but I have given an example below. I have tried several filters, finds, and lengthy code loops with no luck. Anything would help, thanks :)
const object = {
keyone: {
tags: ["game","video","tv","playstation"]
},
keytwo: {
tags: ["book", "sport", "camping", "out"]
}
};
const string = "This is an example, out playstaion, tv and video games are cool!";
// I am trying to locate the key that contains the most tags in a string.
// In this case the result I am looking for would be "keytwo",
// because it's tags have greater occurances inside the string (playstaion, tv, video, game/s).
This should do it, though you might want to consider adding keyword stemming.
const object = {
keyone: {
tags: ["game", "video", "tv", "playstation"]
},
keytwo: {
tags: ["book", "sport", "camping", "out"]
}
};
const string = "This is an example, out playstaion, tv and video games are cool!";
result = {}
for (const [key, value] of Object.entries(object)) {
result[key] = value.tags.reduce((acc, item) => (acc += (string.match(item) || []).length), 0)
}
console.log(result)
Result:
{ keyone: 3, keytwo: 1 }
Edit:
How to count:
let result_key;
let result_count = 0;
for (const [key, value] of Object.entries(object)) {
const result = value.tags.reduce((acc, item) => (acc += (string.match(item) || []).length), 0);
if(result > result_count) {
result_count = result;
result_key = key;
}
}
console.log(result_key, result_count)
Result:
keyone 3
What I would like to do is be able to type an custom property within the back office search. e.g. put the ISBN into the search field and have the results shown currently it always returns "no items found" as the search will only show results for the title node.
How do I enable the content search as seen in the image to search the data in the custom fields?
The data is in the internal index, I have checked the index is working and can see the result with "Examine Management" if I search via the custom data.
The solution is what I used to extend the search

change requests for /umbraco/backoffice/UmbracoApi/Content/GetChildren (the default endpoint for child nodes), and change it to my newly created one, which is located at /umbraco/backoffice/api/CustomListViewSearch/GetChildrenCustom.
This is done easily by adding a js file containing an interceptor like this.
Add file to /App_Plugins/CustomListViewSearch/CustomListViewSearch.js
angular.module('umbraco.services').config([
'$httpProvider',
function ($httpProvider) {
$httpProvider.interceptors.push(function ($q) {
return {
'request': function (request) {
// Redirect any requests for the listview to our custom list view UI
if (request.url.indexOf("backoffice/UmbracoApi/Content/GetChildren?id=") > -1)
request.url = request.url.replace("backoffice/UmbracoApi/Content/GetChildren", "backoffice/api/CustomListViewSearch/GetChildrenCustom");
return request || $q.when(request);
}
};
});
}]);
a package.manifest file in my App_Plugins folder.
{
"javascript": [
"/App_Plugins/CustomListViewSearch/CustomListViewSearch.js"
]
}
If the node Alais isnot working make sure its set in the documnt type (far right on document type name)
I am using asp,net core and have used the tutorial to create sorted, paged and search page (Index). Once I edit an item from this page the controller always dumps me back to the default index page. How do I return to the previous URL. Many thanks.
Here is a section of my controller file.
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Edit(int id, Bind("id,UserPassword,user")] UserProfiles userProfiles)
{
var users = from u in _context.UserProfiles
select u;
if (id != userProfiles.id)
{
return NotFound();
}
if (ModelState.IsValid)
{
try
{
_context.Update(userProfiles);
await _context.SaveChangesAsync();
}
catch (DbUpdateConcurrencyException)
{
if (!UserProfilesExists(userProfiles.id))
{
return NotFound();
}
else
{
throw;
}
}
// ***************
// Redirect to the previous URL,i.e. the Index
return Redirect(TempData["PreviousURL"].ToString()) ;
}
return View(userProfiles);
}
public async Task<IActionResult> Index(string sortOrder, string currentFilter, string searchString, int? page)
{
ViewData["CurrentSort"] = sortOrder;
ViewData["NameSortParm"] = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
// paging
if (searchString != null)
{
page = 1;
}
else
{
searchString = currentFilter;
}
// search
ViewData["CurrentFilter"] = searchString;
var users = from u in _context.UserProfiles
select u;
if (!String.IsNullOrEmpty(searchString))
{
users = users.Where(u => u.user.Contains(searchString)
);
}
//sort
switch (sortOrder)
{
case "name_desc":
users = users.OrderByDescending(u => u.user);
break;
default:
users = users.OrderBy(s => s.user);
break;
}
// ***************
// store the current path and query string in TempData["PreviousURL" session variable
TempData["PreviousURL"] = HttpContext.Request.Path.ToString() + HttpContext.Request.QueryString.ToString();
return View(await PaginatedList<UserProfiles>.CreateAsync(users.AsNoTracking(), page ?? 1, pageSize));
}
This is my first MVC project.
It depends on your logic where controller takes you after saving data.
You need to pass search, sort and paging related data to controller when saving data. You can send them as part of extra post data, as query string parameters or as part of the model itself which is being posted.
After saving data retrieve data based on those parameters and populater your view with that paged, filtred and sorted data.
I solved my problem with the use of session variables: ViewData, ViewBag and TempData. The following two pages were very useful:
https://www.codeproject.com/Articles/476967/What-is-ViewData-ViewBag-and-TempData-MVC-Option
http://andrewlock.net/an-introduction-to-session-storage-in-asp-net-core/
Please see edited question above for the solution.
I have a geojson file which I'm getting from this website which somehow contains corrupt data, with a coordinate value = null.
http://measuringamsterdam.nl/datalist/kijk/
And I'm using it in my code like this:
//Retrieve all data and add to map
$.each(datalistObject['idlist'], function(key, value) {
$.getJSON('http://measuringamsterdam.nl/datalist/kijk/' + value['id'], function(data) {
textbox = value['name'];
var dataid = L.geoJson([data], {
style: function (feature) {
return feature.properties && feature.properties.style;
},
onEachFeature: onEachFeature,
pointToLayer: function (feature, latlng) {
return L.marker(latlng, {
icon: value['icon']
});
}
}).addTo(jsonGroup);
console.log(jsonGroup);
},function(xhr) { console.error(xhr); });
});
Now somehow I need to filter out the features/objects where the coordinates have a null value.
I really need to filter the data that point in my code since I need the + value['id'] part in the getJSON code.
Ane ideas?
Using the following code you will generate a new array. Which will include only the filtered data.
var newArray = data.filter(function (el) {
return el.value != 'null';
});
You can also apply multiple filters, for example:
return el.value_a != 'null' && el.value_b > 100;
Hopefully this will work!
I have a problem that I'm importing some data and each new row depends on previous row being added (since each row has its order attribute set based on current maximum order from other objects). The flow is that I first try to find object with the same name, if not found I first check maximum order and create new object with order + 1 from that query.
I tried doing this with Q promises which are available under Waterline. I tried using all method as well as combining queries with then from Q docs:
var result = Q(initialVal);
funcs.forEach(function (f) {
result = result.then(f);
});
return result;
But all objects had the same order, just like they would be executed in parallel, instead of waiting for the first chain to finish.
I finally found a solution with recurrency, but I doubt it's the best way of working with promises. Here's the code that works (+ needs some refactor and cleaning etc.), to show the rough idea:
function findOrCreateGroup(groupsQuery, index, callback) {
var groupName = groupsQuery[index];
Group.findOne({ 'name' : groupName }).then(function(group) {
if (!group) {
return Group.find().limit(1).sort('order DESC').then(function(foundGroups) {
var maxOrder = 0;
if (foundGroups.length > 0) {
maxOrder = foundGroups[0].order;
}
return Group.create({
'name' : groupName,
'order' : (maxOrder + 1)
}).then(function(g) {
dbGroups[g.name] = g;
if (index + 1 < groupsQuery.length) {
findOrCreateGroup(groupsQuery, index + 1, callback);
} else {
callback();
}
return g;
});
});
} else {
dbGroups[group.name] = group;
if (index + 1 < groupsQuery.length) {
findOrCreateGroup(groupsQuery, index + 1, callback);
} else {
callback();
}
return group;
}
});
}
