Trying to display a set of images from uComponents' MNTP, and can't get a value for the umbracoFile property - in the example below, both umbracoFile and url return empty strings:
foreach (var id in #Model.sliders) {
var media = Model.MediaById(id.InnerText);
if (media != null){
var url = media.umbracoFile;
<p>name = #media.Name</p>
<p>alt = #media.altText</p>
<p>url = #media.umbracoFile</p>
<p>url = #url</p>
}
}
It's getting really really really annoying... I've worked around it in other areas like so, using Model.Media:
<img src="#Model.Media("topRightImage", "umbracoFile")" alt="#Model.Media("topightImage", "altText")" />
But that will only help if with the media picker data type, not mntp. It shouldnt' be that difficult, should it?
I can get the images to load if I rebuild the internal search index, but they're gone again on subsequent refreshes.
I've seen others having similar problems, and would really appreciate a solution...

This looks like a bug that was fixed in 4.7.2. See the following codeplex item:

I'm not the most knowledgeable when dealing with scraping/getting data from a website, so apologies in advance. I have loaded in the HTML file locally, into my project so that I can have a reference and breakdown of the elements:
<div class="price">99</div>
<div class="size">M</div>
I want to select both these div classes, name and price and extract the value(s) which are 99 and M accordingly, how can I do this? I looked at SwiftSoups
let elements = try doc.select("[name=transaction_id]") // query
let transaction_id = try elements.get(0) // select first element
let value = try transaction_id.val() // get value
But that gave me an error. I can see you can select <P> tags, which are paragraphs, but how do I select the specific div class?
Once again, apologies if this is a beginner question.
Thank you.
Edit - The data I wish to parse:
var pstats = {att1:85,att2:92,att3:91,att4:95,att5:38,att6:65,acceleration:91,agility:91,balance:95,jumping:68,reactions:94,sprintspeed:80,stamina:72,strength:69,aggression:44,positioning:93,tactaware:40,vision:95,ballcontrol:96,crossing:85,curve:93,dribbling:96,finishing:95,fkacc:94,headingacc:70,longpass:91,longshot:94,marking:32,penalties:75,shortpass:91,shotpower:86,slidetackle:24,standingtackle:35,volleys:88,composure:96};
Edit 2 - New data I want to parse:
<div style="display: none;" id="player_stats_json">{"test":0,"ppace":85,"pshooting":92,"ppassing":91,"pdribbling":95,"pdefending":38,"pphysical":65,"acceleration":91,"sprintspeed":80,"agility":91,"balance":95,"reactions":94,"ballcontrol":96,"dribbling":96,"positioning":93,"finishing":95,"shotpower":86,"longshotsaccuracy":94,"volleys":88,"penalties":75,"interceptions":40,"headingaccuracy":70,"marking":32,"standingtackle":35,"slidingtackle":24,"vision":95,"crossing":85,"freekickaccuracy":94,"shortpassing":91,"longpassing":91,"curve":93,"jumping":68,"stamina":72,"strength":69,"aggression":44,"composure":96}</div>
If these tags have unique classes you can use getElementsByClass(_:) function and then get the first item, like this:
let price = try doc.getElementsByClass("price").first()?.text()
let size = try doc.getElementsByClass("size").first()?.text()
I'm trying to change the CreateDateTime for a node/document, but it doesn't appear to be having any effect. This is what I'm trying to far:
dynamic node = new DynamicNode(1065);
Document n = new Document(node.Id);
n.CreateDateTime = node.articlePublishedDate;
n.Save();
n.Publish(new umbraco.BusinessLogic.User(0));
umbraco.library.UpdateDocumentCache(n.Id);
Am I going about this in the right way? And also, am I correct in assuming that it can even be changed? The API seems to suggest the CreateDateTime has get/set, so it should work? Running the code through with breakpoints, it updates the CreateDateTime, but something with the save/publish seems to revert it back?
Your code is deprecated, so you need to use the "new" ContentService in umbraco:
https://our.umbraco.org/documentation/Reference/Management-v6/Services/ContentService
It should be something like this:
var cs = Services.ContentService;
var node = cs.GetById(1065);
node.CreateDate = DateTime.Now;
cs.SaveAndPublish(node);
I'm trying to edit the page when my blog displays the Parts.Blogs.BlogPost.List.cshtml. I went to ContentItems under content and added a MediaPicker Field called BlogPostImage to my BlogPosts, and I also made an alternate to Parts.Blogs.BlogPost.List.cshtml in my theme (which is the file I'm editing. The code that I have in there is:
#using Orchard.ContentManagement;
#{
IEnumerable<object> blogPosts =
Model.ContentItems;
}
#if (blogPosts == null || blogPosts.Count() < 1)
{
<p>#T("No posts.")</p>
}
else
{
int count = 0;
<div id="Blog">
<div id="slides">
<div class="slides_container">
#foreach (dynamic post in blogPosts)
{
count++;
string title = post.ContentItem.TitlePart.Title;
ContentItem item = post.ContentItem;
string text = post.ContentItem.BodyPart.Text;
string postImageUrl = post.BlogPostImage.Url;
<div class="slide">
<img src="#postImageUrl" width="625" height="400" alt="Slide #count.ToString()">
<div class="caption" style="bottom: 0">
<h4>#title</h4>
</div>
</div>
}
</div>
</div>
</div>
}
I cannot however figure out how in the world to call that mediapicker field into my list. Any way I try it comes back blank with some kind of querystring in the href. Something like "?23423455657". I took off the variable and that querystring still shows up. What I'm basically trying to accomplish is to put these into a slideshow, with the jquery to start the slideshow in the layout.cshtml. TIA
//SOLUTION:
After days and days of reading and researching I finally found a working solution.
Replacing:
string postImageUrl = post.BlogPostImage.Url;
With:
string postImageUrl = ((ContentItem)post.ContentItem).Parts.SelectMany(p => p.Fields).Where(f => f.Name == "BlogPostImage").First().Storage.Get<string>(null);
Got it from here: http://blog.cloudconstruct.com/post/Creating-a-rotating-image-gallery-in-Orchard-CMS.aspx
I hope it helps anyone stuck in the same boat. I am still curious why I couldn't simply call it the way I had it, but it's working now! :)
You can get the image url using dynamic:
dynamic postItem = post.ContentItem;
var postImageUrl = (string)postItem.BlogPost.BlogPostImage.Url;
Content item, when used as a dynamic object, exposes all its parts (here we're using the part that has the same name as the type, and where the fields are added when adding them from the admin). The part itself has dynamic members for each field (here, BlogPostImage), and from there you can get to the field's properties (Url here).
I tried the above answer with version 1.7 with no joy. I ended up having to download a copy of the source so I could delve into the objects. The below code got me the information I needed and also will help in future when I add extra fields to other content. I used part of the above answer to get to my solution...
IEnumerable<object> blogPosts = Model.ContentItems.ContentItems;
foreach (dynamic post in blogPosts) {
dynamic q = ((ContentItem)post.ContentItem).Parts.SelectMany(p => p.Fields).Where(f => f.Name == "BlogPostImage").First();
string postImageUrl = q.MediaParts[0].MediaUrl;
<img src="#postImageUrl" />
}
Hope this helps somebody.
Hmmm, maybe someone can help me out here or point me in the right direction , as i have been banging my head against the wall for a number of days now and dont seem to be gettin anywhere useful.
(and admittedly i'm pretty new with regards to json,objects, google visulization etc)
essentially, i am running 3 different queries on the same page against 3 different fusion tables, which in return are supposed to return an array of 3 different xets of markers.
all is fine, when i run the queries individually and make an array of the markers .
however, running the 3 queries on the same page, i can't seem to find a way to identify the query in the response function.
any hints much appreciated. and i'll be happy to provide more info if needed (tried to get rid of some unneccessary stuff)
this is what i have. thanks
a) calling the function "setFusionData()" with all relevant vars. something like setFusionData("'LatLng','name'", 2729461);
(this is calles 3 times with different variables)
function setFusionData(selColumns,tableId) {
/****
an actual query example is this:
http://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq="select+'LatLng','name'+from+2729461"
****/
var query = new google.visualization.Query(
'http://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq='+ encodeURIComponent("SELECT "+selColumns+" FROM "+tableId+"")
);
query.send(getFusionData); //do something with the response
}
function getFusionData(response) {
/**
here, is the problem as i need to get the table id or reqId or anything that is uniquely passed on from "setFusionData" above
also something like
alert(JSON.stringify(response)) does not return any reqId or table id either
***/
/*return rows/columns and add values to an array of markers***/
var numRows = response.getDataTable().getNumberOfRows();
var numCols = response.getDataTable().getNumberOfColumns();
for (i = 0; i < numRows; i++) {
/* add markers to array etc this works fine***/
}
}
i also tried something like this:
function setFusionData(selColumns,tableId) {
......
query.send(getFusionData({reqId:tableId}));
}
function getFusionData(response) {
alert(response['reqId']);//returns tableId. but how do i get the tableData ?
}
with wich i can get the reqId, but not the table*Data*. So I am only able to get either id or data :(
----edit----------------
after messing around a bit more (see below) it appears that the key/value pairs that get returned when typing the query into the browser directly are different than what gets returned by the call from the script...i.e the following
http ://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq="select+'LatLng','name'+from+2729461"
typed directly into the browser bar will return
version:'0.5',reqId:'1234',status:'ok',table etc
however, calling the same from within the script returns something like
{
"rj":"0.5","ef":"ok","pb":[],"qb":[],"h":"{"cols":
[{"id":"col2","label":"LatLng","type":"string"},{"id":"col1","label":"name","type":"string"}],
"rows":
[{"c":[{"v":"47.20572,12.70414"},
{"v":"Hohe Tauern"}]},{"c":[{"v":"47.5530395,12.925611"},{"v":"Berchtesgaden"}]},{"c":[{"v":"47.5585405,14.61887"},{"v":"Gesu00e4use"}]}],
"p":{"totalrows":3}
}"
}
, so no 'reqId' but only some cryptic keys (without one that looks like the reqId either)...... anyone any idea why that would/could be ?
Sometimes you can figure it out by just looking at the JSON response, your sample request returns:
google.visualization.Query.setResponse({
version:'0.5',
reqId:'1234',
status:'ok',
table: {
...
}
})
You already got response.reqId to identify which request is this the response for, now you can use response.table to create a new DataTable instance:
var dt = new google.visualization.DataTable(response.table);
Or, since you have multiple tables, put then in an array indexed with the reqId
tables[response.reqId] = new google.visualization.DataTable(response.table);
You'd do var tables = new Array() before calling setFusionData() for the first time.
I m just starting with microsoft (MVC,C#, LINQ), so far so good, but i have a question about LINQ uses, How do i get the value form a LINQ like this one?
var x = from a in db.tablex
where a.eventID == eventID
select new
{
owner = a.owner,
shipper = a.shipper,
consignee = a.consignee
};
I try something like "r.owner" inside a foreach to get the value retrieved from DB
foreach (var r in x)
but its not working.. i dont get intellisense either.. how do i get the value??. I saw several examples and it seems to work like this, but for some reason its not working.. Thanks
Ok guys here was the thing, (it wasnt the typo it was just in the post), i was missing a using :
using System.Reflection;
with this C# automatically creates a class from them, and now it works
What a noob of me =).
foreach (var r in x)
{
var owner = r.owner;// not x.owner
}
