I am stuck with file upload validation in Kohana 3.1. Though the Upload::not_empty function returning false. I am still getting true from check() function.
Here is my code
$validator = Validation::factory($this->request->post())
->rule('name', 'Upload::not_empty', array(':files'))
->bind(':files',$_FILES['name']);
var_dump($validator->check());
Above the name is the name of the file field.
I solved this by combining $_POST and $_FILES as suggested by awellis in this thread.
Basically the value of field name was not passed in Validation::factory so the below code in Kohana_Validation's check() function was not returning the error.
// Ignore return values from rules when the field is empty
if ( ! in_array($rule, $this->_empty_rules) AND ! Valid::not_empty($value))
continue;

My cloud function is not deleting value from the array it is suppose to. It gets all the values correctly as I see in my debug console, but the value in the array is still there.
My code statement is as follows:
for (const id of membersUnderStructure){
const ele = context.params.structure;
console.log(`Deleting ${ele} From ${id}`);
await db.collection(`TeamMember`)
.doc(id)
.update({teamStructIds: admin.firestore.FieldValue.arrayRemove(ele)})
I know the problem is with the admin.firestore.... line as if I put a constant value there, it does update fine. My console shows the correct value of 'ele' and 'id' as well, so the values are correct. The function executes 'ok' without any error but does NOT delete the value of 'ele' from the 'teamStructIds' array.
I am not sure what am I doing wrong here?
Solution:
The Array is of 'Number' and it is trying to delete a String of 'ele'.
I just changed to parseInt(context.parama.structure) and it works now.
My problem is that I am trying to keep the original file that has been uploaded on form update, I have it working that if the file is updated, it updates, but if the field is left blank, the file is then blank rather than simply remaining as the original image.
I have tried to add the value value="{{ book.book_cover_photo }}" to the form input and pass it in as a request.form.get in hopes that the original filename would be saved, but it still returns blank.
I have also tried using an if statement to distinguish between if the filename is empty or not, and if it is leaving it out of the update completely, but this also didnt work and the image was removed from the post.
if 'book_cover_photo' in request.files:
book_cover_photo = request.files['book_cover_photo']
if book_cover_photo.filename != '':
mongo.save_file(secure_filename(book_cover_photo.filename), book_cover_photo)
books = mongo.db.books
books.update({'_id' : ObjectId(book_id)},
{
'book_name' : request.form.get('book_name'),
'book_cover_photo' : book_cover_photo.filename,
})
else:
books = mongo.db.books
books.update({'_id' : ObjectId(book_id)},
{
'book_name' : request.form.get('book_name'),
})
return redirect(url_for('get_books'))
I am not getting any error messages, it updates just fine, the only issue being it overrides so when I refresh my URL is simply /uploads/ rather than /uploads/filename.extension
I created an ActivityNode (an Entry) and I can add custom fields with the
setFields(List<Field> newListField)
fonction.
BUT
I am unable to modify these fields. (In this case I try to modify the value of the field named LIBENTITE)
FieldList list = myEntry.getTextFields();
List<Field> updatedList = new ArrayList<Field>();
//I add each old field in the new list, but I modify the field LIBENTITE
for(Field myField : list){
if(myField.getName().equals("LIBENTITE")){
((TextField)myField).setTextSummary("New value");
}
updatedList.add(myField);
}
myEntry.setFields(updatedList);
activityService.updateActivityNode(myEntry);
This code should replace the old list of fields with the new one, but I can't see any change in the custom field LIBENTITE of myEntry in IBM connections.
So I tried to create a new list of fields, not modifying my field but adding a new one :
for(Field myField:list){
if(!myField.getName().equals("LIBENTITE")){
updatedList.add(myField);
}
}
Field newTextField = new TextField("New Value");
newTextField .setFieldName("LIBENTITE");
updatedList.add(newTextField );
And this code is just adding the new field in myEntry. What I see is that the other custom fields did not change and I have now two custom fields named LIBENTITE, one with the old value and the second with the new value, in myEntry.
So I though that maybe if I clear the old list of Fields, and then I add the new one, it would work.
I tried the two fonctions
myEntry.clearFieldsMap();
and
myEntry.remove("LIBENTITE");
but none of them seems to work, I still can't remove a custom field from myEntry using SBT.
Any suggestions ?
I have two suggestions, as I had (or have) similar problems:
If you want to update an existing text field in an activity node, you have to call node.setField(fld) to update the field in the node object.
Code snippet from my working application, where I'm updating a text field containing a (computed) start time:
ActivityNode node = activityService.getActivityNode(id);
node.setTitle(formatTitle()); // add/update start and end time in title
boolean startFound = false;
// ...
FieldList textfields =node.getTextFields();
Iterator<Field> iterFields = textfields.iterator();
while (iterFields.hasNext()) {
TextField fld = (TextField) iterFields.next();
if (fld.getName().equals(Constants.FIELDNAME_STARTTIME)) {
fld.setTextSummary(this.getStartTimeString()); // NOTE: .setFieldValue does *not* work
node.setField(fld); // write updated field back. This seems to be the only way updating fields works
startFound=true;
}
}
If there is no field with that name, I create a new one (that's the reason I'm using the startFound boolean variable).
I think that the node.setField(fld) should do the trick. If not, there might be a way to sidestep the problem:
You have access to the underlying DOM object which was parsed in. You can use this to tweak the DOM object, which finally will be written back to Connections.
I had to use this as there seems to be another nasty bug in the SBT SDK: If you read in a text field which has no value, and write it back, an error will be thrown. Looks like the DOM object misses some required nodes, so you have to create them yourself to avoid the error.
Some code to demonstrate this:
// ....
} else if (null == fld.getTextSummary()) { // a text field without any contents. Which is BAD!
// there is a bug in the SBT API: if we read a field which has no value
// and try to write the node back (even without touching the field) a NullPointerException
// will be thrown. It seems that there is no value node set for the field. We
// can't set a value with fld.setTextSummary(), the error will still be thrown.
// therefore we have to remove the field, and - optionally - we set a defined "empty" value
// to avoid the problem.
// node.remove(fld.getName()); // remove the field -- this does *not* work! At least not for empty fields
// so we have to do it the hard way: we delete the node of the field in the cached dom structure
String fieldName = fld.getName();
DeferredElementNSImpl fldData = (DeferredElementNSImpl) fld.getDataHandler().getData();
fldData.getParentNode().removeChild(fldData); // remove the field from the cached dom structure, therefore delete it
// and create it again, but with a substitute value
Field newEmptyField = new TextField (Constants.FIELD_TEXTFIELD_EMPTY_VALUE); // create a field with a placeholder value
newEmptyField.setFieldName(fieldName);
node.setField(newEmptyField);
}
Hope that helps.
Just so that post does not stay unanswered I write the answer that was in a comment of the initial question :
"currently, there is no solution to this issue, the TextFields are read-only map. we have the issue recorded on github.com/OpenNTF/SocialSDK/issues/1657"
Using SubSonic 2.2, I have this query:
string q = #"SELECT Media.Id, Media.Title FROM Media WHERE Media.UserId = 7"
DAL.MediumCollection matches = new InlineQuery().ExecuteAsCollection<DAL.MediumCollection>(q).Load();
Looping through "matches" results in every single entry in the "Media" table.
However, when I do this:
IDataReader reader = new InlineQuery().ExecuteReader(q);
It returns the correct rows. Why is ExecuteAsCollection returning something completely different from ExecuteReader? Has anyone else experience this strange behavior?
I think it's because you're calling .Load(). That's overwriting your original query.
ExecuteAsCollection() should do it.
When you call the Load() method it's just like doing new DAL.MediumCollection().Load() that returns all the data in the table.
Hi I am developing using the SharePoint namespace and I ran into the following error when I try to retrieve a URL column from one of my lsits.
"Value does not fall within the expected range"
All I am doing is:
item["URL"]
Can someone tell me what I can do about this?
The error definitely means that the field can't be found.
Debug the process and look at the ListItem.Fields.SchemaXML property to find its internal name, it may be saved internally as something other than URL. You can also use the following method to get a list item value.
SPField l_field = l_item.Fields.GetField("URL");
string l_fieldValue = l_item[l_field.Id].ToString();
The GetField method looks for a field by both DisplayName & InternalName.
To get the URL of an SPListItem, use Item.Url.
public static string GetItemURLValue(SPListItem item, string fieldName)
{
string exit = "";
SPFieldUrlValue link = new SPFieldUrlValue(item[fieldName].ToString());
exit = link.Url;
return exit;
}
This usually means "URL" is not a field in the list.
If it's a promoted InfoPath column, try deactivating and re-activating the form template to the site. I have noticed that I have to do this whenever I add a new promoted field to an infopath template.
There is a special method for retrieving URLs. Try this:
SPListItem li = ...
SPFieldUrlValue fuv = new SPFieldUrlValue(li[strFieldName].ToString());
return fuv.Url;
Mine is a Windows application. I used to get this exception after I created the set up and tried deploying.
My application needed to write in Excel and then save it. I used reference of COM component 'Microsoft Excel 11.0 Object'. I noticed when I add this reference actually 3 dll's appear in my reference list.
Microsoft.office.core
Excel
VBIDE
I removed the 'VBIDE' reference and my problem is solved.
If it's just a column name and in "Single line of Text" format, what about:
item["URL"] != null ? item["URL"].ToString() : "Not Found";
