i want to update only single row column value with rollback commit but when i create table object inside if and pass to insertonsubmit it gives me error,plz help me how can i solve this
var challan = dataContext.Purchase_Challans.Where(t => t.Challan_ID == Convert.ToInt64(ViewState["challanid"]) && t.Company_ID == Convert.ToInt32(Session["CompanyId"])).Select(t => t).ToList();
if (challan.Any())
{
challan.ToList()[0].Inv_DocumentId = dmsPurchaseInvoice.Document_ID;
dataContext.Purchase_Challans.InsertOnSubmit()
dataContext.SubmitChanges();
}
Would be helpful to know more details about the error, but I assume it's because you tell the dataContext to insert an entity that you just retrieved (whereas you want to update it).
Also the code you posted does not even compile and is full of questionable code, like challan.ToList() where it already is a list, or parsing strings inside a delegate.
That said, this code is more straightforward and more likely to work (but to be honest I didn't test it):
var challanId = Convert.ToInt64(ViewState["challanid"]);
var companyId = Convert.ToInt32(ViewState["CompanyId"]);
var challan = dataContext.Purchase_Challans.SingleOrDefault(t => t.Challan_ID == challanId && t.Company_ID == companyId);
if (challan != null)
{
challan.Inv_DocumentId = dmsPurchaseInvoice.Documet_Id;
dataContext.SubmitChanges();
}

I have an Apps Script that copies the content of an template-file to the end of a document. It works with one minor annoyance: the numbered list continues from one copy to the next.
I have many different templates that users can append to the end of the document. Each template is stored in its own Document.
function addSub(template_id){
var mainBody = DocumentApp.getActiveDocument().getBody();
var tempBody = DocumentApp.openById(template_id).getBody();
for(var i = 0;i<tempBody .getNumChildren();i++){
var element = tempBody .getChild(i);
if(element.getType() == DocumentApp.ElementType.TABLE)
mainBody.appendTable(element.copy());
else if(element.getType() == DocumentApp.ElementType.PARAGRAPH)
mainBody.appendParagraph(element.copy());
else if(element.getType() == DocumentApp.ElementType.LIST_ITEM)
mainBody.appendListItem(element.copy());
else if(element.getType() == DocumentApp.ElementType.PAGE_BREAK)
mainBody.appendPageBreak(element.copy());
}
}
It could look like this: ( I want the list to reset for each new copy of the template)
table with name of this template
some raw text
List item1
List item2
table with name of this template
some raw text
List item1
List item2
Do you now that ListItems have an ID, which is a STRING and you can access it via myListItem.getListId().
It seems that all your ListItems have the same ID.
If this is the case, the numbering has to be as you described.
Why do they have the same ListID?
I don't know.
Seems that the body.appendListem method always chooses the same listId.
I didn't test it yet, but you could try to set the listID of the newly append ListItem to that of the original document, if they are different.
Yes, i know, the .copy() method should enclose this information, but the body.appendListItem method may not care.
So, you could try to first save the detached copy of the listItem.
Then append it to the new body.
And then set the id of the newly appended listItem to that of the detached copy.
It's stupid, i know, but it may help.
Didn't try it yet.
And i have little experience with listItems, bit what i saw up to now is that there seems to be only one ListId in the body of a document, if you append or insert listItems.
This could be the cause of the problem.
Hope this helps.
After Richard Gantz solved it, It was corrected by this code:
var listItemDictionary = {};//top
...
else if(element.getType() == DocumentApp.ElementType.LIST_ITEM){
var listCopy = element.copy().asListItem()
var lcID = listCopy.getListId();
if (listItemDictionary[lcID] == null){
var tempLI = mainBody.appendListItem("temp")
listItemDictionary[lcID] = tempLI;
}
Logger.log(lcID)
mainBody.insertListItem(childIndex+j, listCopy.setListId(listItemDictionary[lcID]));
}
...
if(listItemDictionary){//bottom
mainBody.appendParagraph("");
for(var key in listItemDictionary){
listItemDictionary[key].clear().removeFromParent()
}
}
Based on the answer from Niklas Ternvall/Richard Gantz, I found a simpler solution for the case of each template having no more than one list.
function addSub(template_id) {
var mainBody = DocumentApp.getActiveDocument().getBody();
var tempBody = DocumentApp.openById(template_id).getBody();
var listID = null;
for(var i = 0;i<tempBody.getNumChildren();i++){
var element = tempBody.getChild(i).copy();
var type = element.getType();
if(type == DocumentApp.ElementType.TABLE)
mainBody.appendTable(element);
else if(type == DocumentApp.ElementType.PARAGRAPH)
mainBody.appendParagraph(element);
else if(type == DocumentApp.ElementType.LIST_ITEM){
if(listID==null) // First list item
listID = mainBody.appendListItem('temp'); // Define new listID
mainBody.appendListItem(element).setListId(listID); // Apply to copy
}
else if(type == DocumentApp.ElementType.PAGE_BREAK)
mainBody.appendPageBreak(element);
}
mainBody.removeChild(listID); // Delete temporary list item
}
Each time you call the function, listID=null is the indicator for whether or not there have been any list items in the template. When you get to the first list item, appending the text 'temp' forces a new list and hence a new listID that you can apply to the list items from the template. After you finish going through the template, mainBody.removeChild(listID) removes 'temp' from the top of your list.
This solution worked for me when using one template 100 times in one document, essentially as a mail merge. I'm fairly new to Apps Script, so I would appreciate any feedback if there is a reason this wouldn't work for a single-list template.
When I have an array of Sitecore IDs, for example TargetIDs from a MultilistField, how can I query the ContentSearchManager to return all the SearchResultItem objects?
I have tried the following which gives an "Only constant arguments is supported." error.
using (var s = Sitecore.ContentSearch.ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
{
rpt.DataSource = s.GetQueryable<SearchResultItem>().Where(x => f.TargetIDs.Contains(x.ItemId));
rpt.DataBind();
}
I suppose I could build up the Linq query manually with multiple OR queries. Is there a way I can use Sitecore.ContentSearch.Utilities.LinqHelper to build the query for me?
Assuming I got this technique to work, is it worth using it for only, say, 10 items? I'm just starting my first Sitecore 7 project and I have it in mind that I want to use the index as much as possible.
Finally, does the Page Editor support editing fields somehow with a SearchResultItem as the source?
Update 1
I wrote this function which utilises the predicate builder as dunston suggests. I don't know yet if this is actually worth using (instead of Items).
public static List<T> GetSearchResultItemsByIDs<T>(ID[] ids, bool mustHaveUrl = true)
where T : Sitecore.ContentSearch.SearchTypes.SearchResultItem, new()
{
Assert.IsNotNull(ids, "ids");
if (!ids.Any())
{
return new List<T>();
}
using (var s = Sitecore.ContentSearch.ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
{
var predicate = PredicateBuilder.True<T>();
predicate = ids.Aggregate(predicate, (current, id) => current.Or(p => p.ItemId == id));
var results = s.GetQueryable<T>().Where(predicate).ToDictionary(x => x.ItemId);
var query = from id in ids
let item = results.ContainsKey(id) ? results[id] : null
where item != null && (!mustHaveUrl || item.Url != null)
select item;
return query.ToList();
}
}
It forces the results to be in the same order as supplied in the IDs array, which in my case is important. (If anybody knows a better way of doing this, would love to know).
It also, by default, ensures that the Item has a URL.
My main code then becomes:
var f = (Sitecore.Data.Fields.MultilistField) rootItem.Fields["Main navigation links"];
rpt.DataSource = ContentSearchHelper.GetSearchResultItemsByIDs<SearchResultItem>(f.TargetIDs);
rpt.DataBind();
I'm still curious how the Page Editor copes with SearchResultItem or POCOs in general (my second question), am going to continue researching that now.
Thanks for reading,
Steve
You need to use the predicate builder to create multiple OR queries, or AND queries.
The code below should work.
using (var s = Sitecore.ContentSearch.ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
{
var predicate = PredicateBuilder.True<SearchResultItem>();
foreach (var targetId in f.Targetids)
{
var tempTargetId = targetId;
predicate = predicate.Or(x => x.ItemId == tempTargetId)
}
rpt.DataSource = s.GetQueryable<SearchResultItem>().Where(predicate);
rpt.DataBind();
}
Often, I need to loop through an Ember.ArrayProxy object's content.
Exemple 1, I need to build a list of IDs:
var loc = myArrayProxy.get('length') || 0,
ids = new Array(),
idsList;
while(--loc >= 0) {
var curObject = myArrayProxy.objectAt(loc);
ids.push(curObject.id);
}
idsList = ids.join(',');
Exemple 2, I need to build an Array of primitive objects (not Ember.Object):
var loc = myArrayProxy.get('length') || 0,
newContent = new Array();
while(--loc >= 0) {
var curObject = myArrayProxy.objectAt(loc);
newContent.push({
id: curObject.id,
name: curObject.name
});
}
Question: is there a better way to do this? The "while(--loc >= 0)" seems bad to me.
Ember.ArrayProxy provides many friendly functions (through Ember.Array, Ember.Enumerable, ...). Loops can often be avoided using "forEach". In your 2nd example, you may consider using "map".
Here is a link to Ember.ArrayProxy documentation.
Be sure to look at: Ember.Array and Ember.Enumerable
edit:
For instance, assuming the order of the ids is not relevant, your first example could be written:
var idsList = myArrayProxy.mapProperty('id').join(',');
Is there a way to retrieve the set-at-creations properties of an EmberJS object if you don't know all your keys in advance?
Via the inspector I see all the object properties which appear to be stored in the meta-object's values hash, but I can't seem to find any methods to get it back. For example object.getProperties() needs a key list, but I'm trying to create a generic object container that doesn't know what it will contain in advance, but is able to return information about itself.
I haven't used this in production code, so your mileage may vary, but reviewing the Ember source suggests two functions that might be useful to you, or at least worth reviewing the implementation:
Ember.keys: "Returns all of the keys defined on an object or hash. This is useful when inspecting objects for debugging. On browsers that support it, this uses the native Object.keys implementation." Object.keys documentation on MDN
Ember.inspect: "Convenience method to inspect an object. This method will attempt to convert the object into a useful string description." Source on Github
I believe the simple answer is: you don't find a list of props. At least I haven't been able to.
However I noticed that ember props appear to be prefixed __ember, which made me solve it like this:
for (f in App.model) {
if (App.model.hasOwnProperty(f) && f.indexOf('__ember') < 0) {
console.log(f);
}
};
And it seems to work. But I don't know whether it's 100% certain to not get any bad props.
EDIT: Adam's gist is provided from comments. https://gist.github.com/1817543
var getOwnProperties = function(model){
var props = {};
for(var prop in model){
if( model.hasOwnProperty(prop)
&& prop.indexOf('__ember') < 0
&& prop.indexOf('_super') < 0
&& Ember.typeOf(model.get(prop)) !== 'function'
){
props[prop] = model[prop];
}
}
return props;
}
Neither of these answers are reliable, unfortunately, because any keys paired with a null or undefined value will not be visible.
e.g.
MyClass = Ember.Object.extend({
name: null,
age: null,
weight: null,
height: null
});
test = MyClass.create({name: 'wmarbut'});
console.log( Ember.keys(test) );
Is only going to give you
["_super", "name"]
The solution that I came up with is:
/**
* Method to get keys out of an object into an array
* #param object obj_proto The dumb javascript object to extract keys from
* #return array an array of keys
*/
function key_array(obj_proto) {
keys = [];
for (var key in obj_proto) {
keys.push(key);
}
return keys;
}
/*
* Put the structure of the object that you want into a dumb JavaScript object
* instead of directly into an Ember.Object
*/
MyClassPrototype = {
name: null,
age: null,
weight: null,
height: null
}
/*
* Extend the Ember.Object using your dumb javascript object
*/
MyClass = Ember.Object.extend(MyClassPrototype);
/*
* Set a hidden field for the keys the object possesses
*/
MyClass.reopen({__keys: key_array(MyClassPrototype)});
Using this method, you can now access the __keys field and know which keys to iterate over. This does not, however, solve the problem of objects where the structure isn't known before hand.
I use this:
Ember.keys(Ember.meta(App.YOUR_MODEL.proto()).descs)
None of those answers worked with me. I already had a solution for Ember Data, I was just after one for Ember.Object. I found the following to work just fine. (Remove Ember.getProperties if you only want the keys, not a hash with key/value.
getPojoProperties = function (pojo) {
return Ember.getProperties(pojo, Object.keys(pojo));
},
getProxiedProperties = function (proxyObject) {
// Three levels, first the content, then the prototype, then the properties of the instance itself
var contentProperties = getPojoProperties(proxyObject.get('content')),
prototypeProperties = Ember.getProperties(proxyObject, Object.keys(proxyObject.constructor.prototype)),
objectProperties = getPojoProperties(proxyObject);
return Ember.merge(Ember.merge(contentProperties, prototypeProperties), objectProperties);
},
getEmberObjectProperties = function (emberObject) {
var prototypeProperties = Ember.getProperties(emberObject, Object.keys(emberObject.constructor.prototype)),
objectProperties = getPojoProperties(emberObject);
return Ember.merge(prototypeProperties, objectProperties);
},
getEmberDataProperties = function (emberDataObject) {
var attributes = Ember.get(emberDataObject.constructor, 'attributes'),
keys = Ember.get(attributes, 'keys.list');
return Ember.getProperties(emberDataObject, keys);
},
getProperties = function (object) {
if (object instanceof DS.Model) {
return getEmberDataProperties(object);
} else if (object instanceof Ember.ObjectProxy) {
return getProxiedProperties(object);
} else if (object instanceof Ember.Object) {
return getEmberObjectProperties(object);
} else {
return getPojoProperties(object);
}
};
In my case Ember.keys(someObject) worked, without doing someObject.toJSON().
I'm trying to do something similar, i.e. render a generic table of rows of model data to show columns for each attribute of a given model type, but let the model describe its own fields.
If you're using Ember Data, then this may help:
http://emberjs.com/api/data/classes/DS.Model.html#method_eachAttribute
You can iterate the attributes of the model type and get meta data associated with each attribute.
This worked for me (from an ArrayController):
fields: function() {
var doc = this.get('arrangedContent');
var fields = [];
var content = doc.content;
content.forEach(function(attr, value) {
var data = Ember.keys(attr._data);
data.forEach(function(v) {
if( typeof v === 'string' && $.inArray(v, fields) == -1) {
fields.push(v);
}
});
});
return fields;
}.property('arrangedContent')

I have a cfgrid that that is based on a query. It is not bound to a cfc function because I want a scrolling grid, not a paged grid (you must supply the page number and page size if you use BIND).. I can figure out how to make it filter on one column by using the following code, but I really need to filter on three columns...
grid.getDataSource().filter("OT_MILESTONE",t1);
Adding more to the filter string does not do the trick...it ignores anything more than the first pair of values..
so..I thought if I called a function that passes the three values and returned the query results to me, I could replace the Data Store for the grid..but I cannot figure out the syntax to get it to replace.
The returned variable for the query has the following format:
{"COLUMNS":["SEQ_KEY","ID","OT_MILESTONE"],"DATA":[[63677,"x","y"]]}
Any ideas?
have you looked at queryconvertforgrid()?
http://www.cfquickdocs.com/cf9/#queryconvertforgrid
Update: have you looked at these?

http://cfsilence.com/blog/client/index.cfm/2007/8/9/Filtering-Records-In-An-Ajax-Grid
after much blood, sweat, tears and swearing..here's the answer, in case anyone else might need to filter a cfgrid by more than one variable:
var w1 = ColdFusion.getElementValue('wbs');
var t1 = ColdFusion.getElementValue('task');
var p1 = ColdFusion.getElementValue('project');
grid = ColdFusion.Grid.getGridObject('data');
store = grid.getDataSource();
store.clearFilter();
store.filterBy(function myfilter(record) {
var wantit = true;
if (trim(w1) != '') {
if(record.get('WBS_ID') != w1) {
wantit = false;
}}
if (trim(t1) != '') {
if(record.get('OT_MILESTONE') != t1) {
wantit = false;
}}
if (trim(p1) != '') {
if(record.get('PROJECT') != p1) {
wantit = false;
}}
return wantit;
});
ColdFusion.Grid.refresh('data',false);
you will need a JS trim function...
Make sure the column names are caps...
