I am saving a .pdf/.docx file when creating a entry in y grails-app. Now on the click of Delete button I want to remove that entry from DB as well as I also want to delete the .pdf/.docx file from the folder.
Note : I am saving the path of the file in my DB.
Deleting file from physical location is as simple as this -
def file = new File(/C:\Users\Public\Pictures\Sample Pictures\Chrysanthemum.jpg/)
file.delete()
String filePath = fileDomainObject.filePath
boolean fileSuccessfullyDeleted = new File(filePath).delete()
if(fileSuccessfullyDeleted ){
fileDomainObject.delete flush:true
}
else{
flash.error = "Error in deletion."
return
}

I am creating a pst from message files which are located in another machine on a same network. But when I loaded the pst, messages are not rendered. I have added a screenshot. And code is below:
Issue do not occur when message files are imported from my local machine.
private static void GeneratePST(string [] messageFiles, string outputPstPath)
{
RDOSession pstSession = null;
RDOPstStore store = null;
RDOFolder folder = null;
RDOMail rdo_Mail = null;
RDOItems items = null;
try
{
pstSession = new RDOSession();
store = pstSession.LogonPstStore(outputPstPath, 1, Path.GetFileNameWithoutExtension(outputPstPath));
folder = store.IPMRootFolder;
folder = folder.Folders.Add("Loose Messages");
foreach (string messages in messageFiles)
{
items = folder.Items;
rdo_Mail = items.Add("IPM.NOTE");
rdo_Mail.Import(messages, rdoSaveAsType.olMSG);
rdo_Mail.Save();
}
}
catch (Exception ex)
{
//log exception
}
finally
{
Marshal.ReleaseComObject(rdo_Mail);
Marshal.ReleaseComObject(folder);
Marshal.ReleaseComObject(store);
Marshal.ReleaseComObject(items);
pstSession.Logoff();
Marshal.ReleaseComObject(pstSession);
GC.Collect();
}
}
I have also impersonated the network machine before importing message file. But still the issue persist.
The problem only exists for files in another machine. Messages are rendered for msg file located in my machine. Also, I noticed issue is only with message files. Eml file are rendered. So, it might not be the issue of impersonation.
Any help please.
Microsoft does not support accessing PST files on network drives. They must be on a local machine.
Also, there is no reason to continuously retrieve the RDOItems object - you never release on the old value, so those objects stay alive until your app exits. Ditto for the rdo_Mail object:
folder = folder.Folders.Add("Loose Messages");
items = folder.Items;
foreach (string messages in messageFiles)
{
if (rdo_Mail != null) Marshal.ReleaseComObject(rdo_Mail);
rdo_Mail = items.Add("IPM.NOTE");
rdo_Mail.Import(messages, rdoSaveAsType.olMSG);
rdo_Mail.Save();
}
I know we can not put the plist or other cache file in the root directory of our project.
But if is .db file, is it could put in the root directory of our project, let us insert or delete table in the db file ?
Because I see a demo it is puts in the root directory, it works fine, but I use this in my project, can not insert data to it.
This method I invoke it returns 4, sometime is 2:
// Private method which handles the actual execution of an SQL statement
private func execute(stmt:OpaquePointer, sql:String)->CInt {
// Step
var result = sqlite3_step(stmt)
if result != SQLITE_OK && result != SQLITE_DONE {
sqlite3_finalize(stmt)
if let error = String(validatingUTF8:sqlite3_errmsg(self.db)) {
let msg = "SQLiteDB - failed to execute SQL: \(sql), Error: \(error)"
NSLog(msg)
}
return 0
}
// Is this an insert
let upp = sql.uppercased()
if upp.hasPrefix("INSERT ") {
// Known limitations: http://www.sqlite.org/c3ref/last_insert_rowid.html
let rid = sqlite3_last_insert_rowid(self.db)
result = CInt(rid)
} else if upp.hasPrefix("DELETE") || upp.hasPrefix("UPDATE") {
var cnt = sqlite3_changes(self.db)
if cnt == 0 {
cnt += 1
}
result = CInt(cnt)
} else {
result = 1
}
// Finalize
sqlite3_finalize(stmt)
return result
}
But I use SQLPro for SQLite tool to see the table (which I create by this tool)， the table did not insert any records.
So, if we can put the db file in the root directory, let us to insert or delete data in the db file ?
You can insert, update or delete rows (thus modify your db file) only if it is located in Document directory
See this other answer to discover how to move your .db file at app launch
I have a web app that uploads files to file system and show them in a list. I am trying to delete the item with a button. I know I need to get the path of the directory file to be able to delete it and I believe this is where I am stuck:
def delete = {
def doc = Document.get(params.id)
def path = Document.get(path.id)
doc.delete(path)
redirect( action:'list' )
}
error I am getting: No such property: path for class: file_down.DocumentController Possible solutions: flash
It seems to me def path = Document.get(path.id) is wrong, in that case how do we find the path of a document ?
This is my upload method where I upload the files, assign it to a specific filesize, date, and fullPath( which is the uploaded folder)
def upload() {
def file = request.getFile('file')
if(file.empty) {
flash.message = "File cannot be empty"
} else {
def documentInstance = new Document()
documentInstance.filename = file.originalFilename
documentInstance.fullPath = grailsApplication.config.uploadFolder + documentInstance.filename
documentInstance.fileSize = file.getSize() / (1024 * 1024)
documentInstance.company = Company.findByName(params.company)
if (documentInstance.company == null) {
flash.message = "Company doesn't exist"
redirect (action: 'admin')
}
else {
file.transferTo(new File(documentInstance.fullPath))
documentInstance.save()
redirect (action:'list', params: ['company': params.company])
}
}
}
I think you have an error in this line:
def path = Document.get(path.id)
You try to get path.id from the path variable you are just declaring.
I'm pretty sure that you mean
def path = new File(doc.fullPath)
path.delete() // Remove the file from the file-system
doc.delete() // Remote the domain instance in DB
Alternative:
class Document {
// Add this to your Document domain
def beforeDelete = {
new File(fullPath).delete()
}
}
and then you could just do this in your controller:
def delete = {
def doc = Document.get(params.id)
doc.delete() // Delete the domain instance in DB
redirect( action:'list' )
}
In my application am allowing the user to upload URL of the PDF file. i want to grab only the file name from the URL.
For example: If user uploads the URL as www.gradsch.ohio-state.edu/Depo/ETD_Tutorial/lesson2.pdf than lesson2.pdf should get extracted
code:
function load_file(box) {
var file = document.getElementById('file');
if (file == "") {
alert("Enter File URL");
return false;
}
}
How can i grab only the file name from the URL
As
file.substring
you point on container and try to use substring method on it, not on it's content.
You should use
file.innerHTML.substring instead.
Try using: file.text() or file.val()
Eg.:
return file.text().substring(file.text().lastIndexOf("/") + 1, file.text().lastIndexOf("."));
Or,
return file.val().substring(file.val().lastIndexOf("/") + 1, file.val().lastIndexOf("."));
I'm implementing a file upload functionality to a web-app in Grails. This includes adapting existing code to allow multiple file extensions. In the code, I've implemented a boolean to verify that the file path exists, but I'm still getting a FileNotFoundException that /hubbub/images/testcommand/photo.gif (No such file or directory)
My upload code is
def rawUpload = {
def mpf = request.getFile("photo")
if (!mpf?.empty && mpf.size < 200*1024){
def type = mpf.contentType
String[] splitType = type.split("/")
boolean exists= new File("/hubbub/images/${params.userId}")
if (exists) {
mpf.transferTo(new File("/hubbub/images/${params.userId}/picture.${splitType[1]}"))
} else {
tempFile = new File("/hubbub/images/${params.userId}").mkdir()
mpf.transferTo(new File("/hubbub/images/${params.userId}/picture.${splitType[1]}"))
}
}
}
I'm getting the exception message at
if (exists) {
mpf.transferTo(new File("/hubbub/images/${params.userId}/picture.${splitType[1]}"))
}
So, why is this error happening, as I'm simply collatating an valid existing path as well as a valid filename and extension?
Why do you think that convertation of File object to Boolean returns existence of a file?
Try
File dir = new File("/hubbub/images/${params.userId}")
if (!dir.exists()) {
assert dir.mkdirs()
}
mpf.transferTo(new File(dir, "picture.${splitType[1]}"))
