I have a text file say data.txt which contains content of format:
( {
city = Leesburg;
country = USA;
dob = "";
email = "email#domain.com";
firstName = "EricM.";
homePhone = "";
lastName = Abcdef;
mobilePhone = 12312312;
state = Virginia;
workPhone = 12312312;
},
{
city = "Mt. Uncle";
dob = "";
email = "";
firstName = first;
homePhone = "";
lastName = Berry;
mobilePhone = 234234;
state = MD;
workPhone = "";
}
)
require "json"
file = File.open("data.txt")
contents = file.read
hashes = contents.scan(/{(.*?)}/mx)
arr = []
hashes.each do |hash|
hashitems = hash[0].scan(/(\w+\s=\s.+?);/)
ahash = {}
hashitems.each do |hashitem|
itemarr = hashitem[0].split(" = ")
ahash[itemarr[0]] = itemarr[1]
end
arr << ahash
end
print JSON.dump(arr)
What I've done here is use two regex functions to break down your data into a Ruby object, then I've used the JSON library to dump the object to JSON.

We have worked on this code to error trap a value entered in a Edit Text field
When the value is entered correctly we are informed that the entered value does not match
BUT if we select the value from a recycler view list and populate the Edit Text field with the value the search tells us we have a match
Here is the code for the search in the DBHelper
fun getOneName(id: Int): Contact? {
val db = this.writableDatabase
val selectQuery = "SELECT * FROM $TABLE_NAME WHERE $colId = ?"
db.rawQuery(selectQuery, arrayOf(id.toString())).use { // .use requires API 16
if (it.moveToFirst()) {
val result = Contact(id = 0,name ="")
result.id = it.getInt(it.getColumnIndex(colId))
result.name = it.getString(it.getColumnIndex(colName))
return result
}
}
return null
}
We used this for the Model Class our first time using data class as just plain class
data class Contact (
var id: Int,
var name: String
)
And here is the button click that manages the search
btnGetID.setOnClickListener {
if(etPerson.text.toString().trim().isNullOrEmpty()){
message("Enter Contact Name")
return#setOnClickListener
}
var numeric = true
var string = etPerson.text.toString().trim()
numeric = string.matches(".*\\d+.*".toRegex())
if(numeric){
message("No NUMBERS")
return#setOnClickListener
}
val dbManager = DBHelper(this)
var name = etPerson.text.toString()
//val contact = dbManager.getOneName(name)
val contact = dbManager.getOneName(id.toInt())
if(contact?.name.equals(name)){
println("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! contact ID= "+contact)
etPerson.setText("The contact name is $name the ID is "+contact?.id.toString())
}else{
etPerson.setText("Name NOT = to $name and the ID is "+contact?.id.toString())
}
}
We know the name Sally is in the DB if we type Sally in the else statement shows Name NOT = bla
If we select Sally from the Recyclerview List the first statement shows The contact name bla bla
Kotlin 1.2.71 API 27
Our question is why is the hand typed name failing if it mataches?
HERE IS THE CORRECT CODE FOR THE DBHelper
fun getOneName(name: String): Contact? {
val db = this.writableDatabase
val selectQuery = "SELECT * FROM $TABLE_NAME WHERE $colName = ?"
db.rawQuery(selectQuery, arrayOf(name)).use { // .use requires API 16
if (it.moveToFirst()) {
val result = Contact(id = 0,name ="")
result.id = it.getInt(it.getColumnIndex(colId))
result.name = it.getString(it.getColumnIndex(colName))
return result
}
}
return null
}
var result = (from p in db.push_notifications
join nu in db.notification_recievers on p.id equals nu.push_notification_id
join nt in db.notification_types on p.notification_type_id equals nt.id
where (p.id == pushNotificationId && p.send_criteria == criteria && nu.delete_flag == false && p.delete_flag == false && nt.delete_flag == false)
select new NotificationList
{
conferenceId = p.conference_id,
pushNotificationId = p.id,
notificationId = nt.id,
notificationType = nt.notification_type,
nottificationDate = p.created_dt_tm,
criteria = (int)p.send_criteria,
notificationMessage = p.notification_msg,
userEmail=null,
userInterests = **getInterestNamesByPushNotificationId(p.id)**,
userEvents=null
}).Distinct();
public string getInterestNamesByPushNotificationId(int id)
{
string interests = string.Empty;
var query = from i in db.interests
join pn in db.notification_recievers
on i.id equals pn.interest_id
where pn.push_notification_id == id && pn.delete_flag == false
select new
{
name = i.name
};
foreach (var intr in query.Distinct())
{
if (interests == "")
{
interests = intr.name;
}
else
{
interests = interests + ", " + intr.name;
}
}
return interests;
}
this is throwing me error
LINQ to Entities does not recognize the method 'System.String
getInterestNamesBy PushNotification(Int32)' method, and this method
cannot be translated into a store expression.
The Entity Framework is trying to execute your LINQ clause on the SQL side, obviously there is no equivalent to 'getInterestNamesBy PushNotification(Int32)' from a SQL perspective.
You need to force your select to an Enumerable and then reselect your object using the desired method.
Not ideal but something like this should work - (not tested this so be nice).
var result = (from p in db.push_notifications
join nu in db.notification_recievers on p.id equals nu.push_notification_id
join nt in db.notification_types on p.notification_type_id equals nt.id
where (p.id == pushNotificationId && p.send_criteria == criteria && nu.delete_flag == false && p.delete_flag == false && nt.delete_flag == false)
select new { p=p, nu = nu, nt = nt }).AsEnumerable().Select( x => new NotificationList()
{
conferenceId = x.p.conference_id,
pushNotificationId = x.p.id,
notificationId = x.nt.id,
notificationType = x.nt.notification_type,
nottificationDate = x.p.created_dt_tm,
criteria = (int)x.p.send_criteria,
notificationMessage = x.p.notification_msg,
userEmail=null,
userInterests = getInterestNamesByPushNotificationId(x.p.id),
userEvents=null
}).Distinct();
i have done it this way
In my model
using (NotificationService nService = new NotificationService())
{
modelView = nService.DetailsOfNotifications(pushNotificationId, criteriaId).Select(x => new NotificationViewModelUI(x.conferenceId, x.pushNotificationId, x.notificationId, x.notificationType, x.nottificationDate, x.criteria, x.notificationMessage, x.userEmail, nService.getInterestNamesByPushNotificationId(x.pushNotificationId), nService.getIEventTitlesByPushNotificationId(x.pushNotificationId))).ToList();
}
public NotificationViewModelUI(int conferenceId, int pushNotificationId, int notificationId, string notificationType, DateTime dateTime, int criteria, string nMessage, string emailId = null, string interestNames = null, string eventTitles = null)
{
this.conferenceId = conferenceId;
this.pushNotificationId = pushNotificationId;
this.notificationId = notificationId;
this.notificationType = notificationType;
this.notificationDate = dateTime;
this.sendCriteria = (NotificationCriteria)criteria;
this.notificationMessage = nMessage;
this.emailId = NotificationCriteria.SpecificUser.Description() +"... "+ emailId;
this.interestNames = NotificationCriteria.UserByInterests.Description() + "... " + interestNames;
this.eventTitles = NotificationCriteria.UserByEvents.Description() + "... " + eventTitles;
}
I was wondering if there is a way to display more readable description of managed object in XCode 6 when developping in Swift.
Cause now it displays :
//Printing description of station:
(targetName.BDD_Station) station = 0x00000001700dfdb0 {
targetName.BDD_Station = {
CoreData.NSManagedObject = {
ObjectiveC.NSObject = {}
}
}
Before it was nicer :)
<BDD_Station: 0x1702d6180> (entity: BDD_Station; id: 0xd0000000bb7c0008 <x-coredata://DFA941DB-A7E7-406F-B415-B628AA4D8FF1/BDD_Station/p11999> ; data: {
address = "254, Alexander Platz ";
address2 = "";
area = 72;
"brand_code" = TAC;
"brand_id" = 420;
"brand_name" = "HARIBO";
cheapest = nil;
city = PARIS;
code = NF000337;
"corporate_name" = nil;
country = FRANCE;
department = nil;
distance = 0;
email = "";
fax = nil;
ident = 827752;
latitude = "48.1278";
longitude = "-2.64937";
"map_id" = 744;
name = "my beautiful name";
"original_name" = nil;
phone = 0143543211;
toDelete = 0;
zip = 72000;
})
I tried to override var description, but it does'nt get called when I click "show description" in debugger.
Thanks for your help.
I was trying to change the table names in the entity model or database but the old names are already use in many places in the application. Is there any way to auto reflect renamed entities or tables in the LINQ query or code.
Let say I have tables tblDepartment, tblEmployee and tblEmployeeDepartment. These tables are used in the code(LINQ) on many places. I like to change these tables names to Department, Employee and EmployeeDepartment. So, is there anyway to auto reflect name in LINQ or code when I change table names either using Database First or Model First approach.
P.S. The application is based on .Net 3.5

Using MVC3 and razor along with NuGet Doddle Report, I have built a nice report that opens a view model in Excel. I would like to allow the user to supply a filter and sort on the view before the report is exported to Excel.
Are there recommended ways to do this or resources I could check out?
Thanks!
