I have a table called UserManagement that contains information about the user.This table gets updated whenever new user is created. If i create two users then i need check whether two users are actually created or not. Table contains ID,UserName,FirstName,LastName,Bdate..ctc. Here ID will be generated automatically.
I am running Selenium-TestNG script.Using Selenium,how can i get the UserName of the two users which i have created? Should i have to iterate through table? If so how to iterate through the table?
Use ISelenium.GetTable(string) to get the contents of the table cells you want. For example,
selenium.GetTable("UserManagement.0.1");
will return the contents of the table's first row and second column. You could then assert that the correct username or usernames appear in the table.
Get the count of rows using Selenium.getxpathcount(\#id = fjsfj\td\tr") in a variable rowcount
Give the columncount in a variable
Ex:
int colcount = 5;
Give the req i.e New user
String user1 = "ABC"
for(i = 0;i <=rowcount;i++)
{
for(j=0;j<=colcount;j++)
{
if (user1==selenium.gettable("//#[id=dldl/tbody" +i "td"+j))
{
system.out.println(user1 + "Inserted");
break;
}
break;
}
}
Get the number of rows using:
int noOfRowsInTable = selenium.getXpathCount("//table[#id='TableId']//tr");
If the UserName you want to get is at fixed position, let's say at 2nd position, then for each row iterate as given below:
selenium.getText("xpath=//table[#id='TableId']//tr//td[1]");
Note: we can find the number of columns in that table using same procedure
int noOfColumnsInTable = selenium.getXpathCount("//table[#id='TableId']//tr//td");
Generically, something like this?
table = #browser.table(:id,'tableID')
table.rows.each do |row|
# perform row operations here
row.cells.each do |cell|
# do cell operations here
end
end

So I have 2 variable for storing the selected time of the user ('time_to' and 'time_from) with these sample data('7:30','8:00')
How can I save these two into 1 column('c_time') so it would look like this('7:30-8:00')?
if i understand you correctly, you can create a column of string (varchar) type. and then create the data for your column like this :
$time_to = '7:30';
$time_from= '8:00';
$colValueToBeStored = "(".$time_to."-".$time_from.")";
then just put $colValueToBeStored inside your column.
and to reverse it:
$colValueToBeStored = "(7:30-8:00)";
$res = explode("-",str_replace([")","("],"",$colValueToBeStored));
$time_to = $res[0];
$time_from = $res[1];
define your c_time column type as JSON, that way you can store multiple values, as it will be easier to retrieve as well. Like,
...
$cTime['time_to'] = "7:30";
$cTime['time_from'] = "8:00";
$cTimeJson = json_encode($cTime);
// save to db
...
Suppose I have a user table with columns id, name, age
With a normal get query User::get(), I get all results with those column's value.
But instead of just getting the id, name, age columns, is it possible if I add another column, perhaps a column with an alias of future_age with a value of age + 1.
The above result could be achieved in SQL like so:
SELECT res.*, (SELECT sum(res.age+1) from users where id = res.id) as future_age from users as res
I've thought about looping through the result and creating new key. but I think this would make the query execution time slow when the data is lengthy.
Is it possible to create the future_age key/column (I don't know the term hehe) directly on the query?
Currently, this is my query:
$user = User::get();
$new_res = []
if($user->count() > 0) {
foreach ($user as $u) {
$u['future_age'] = $u->age + 1
$new_res[] = $u;
}
}
The query works tho, but I don't think this is good if I have a large set of data.
Lets say I have a table like so:
{
value = 4
},
{
value = 3
},
{
value = 1
},
{
value = 2
}
and I want to iterate over this and print the value in order so the output is like so:
1
2
3
4
How do I do this, I understand how to use ipairs and pairs, and table.sort, but that only works if using table.insert and the key is valid, I need to be loop over this in order of the value.
I tried a custom function but it simply printed them in the incorrect order.
I have tried:
Creating an index and looping that
Sorting the table (throws error: attempt to perform __lt on table and table)
And a combination of sorts, indexes and other tables that not only didn't work, but also made it very complicated.
I am well and truly stumped.
Sorting the table
This was the right solution.
(throws error: attempt to perform __lt on table and table)
Sounds like you tried to use a < b.
For Lua to be able to sort values, it has to know how to compare them. It knows how to compare numbers and strings, but by default it has idea how to compare two tables. Consider this:
local people = {
{ name = 'fred', age = 43 },
{ name = 'ted', age = 31 },
{ name = 'ned', age = 12 },
}
If I call sort on people, how can Lua know what I intend? I doesn't know what 'age' or 'name' means or which I'd want to use for comparison. I have to tell it.
It's possible to add a metatable to a table which tells Lua what the < operator means for a table, but you can also supply sort with a callback function that tells it how to compare two objects.
You supply sort with a function that receives two values and you return whether the first is "less than" the second, using your knowledge of the tables. In the case of your tables:
table.sort(t, function(a,b) return a.value < b.value end)
for i,entry in ipairs(t) do
print(i,entry.value)
end
If you want to leave the original table unchanged, you could create a custom 'sort by value' iterator like this:
local function valueSort(a,b)
return a.value < b.value;
end
function sortByValue( tbl ) -- use as iterator
-- build new table to sort
local sorted = {};
for i,v in ipairs( tbl ) do sorted[i] = v end;
-- sort new table
table.sort( sorted, valueSort );
-- return iterator
return ipairs( sorted );
end
When sortByValue() is called, it clones tbl to a new sorted table, and then sorts the sorted table. It then hands the sorted table over to ipairs(), and ipairs outputs the iterator to be used by the for loop.
To use:
for i,v in sortByValue( myTable ) do
print(v)
end
While this ensures your original table remains unaltered, it has the downside that each time you do an iteration the iterator has to clone myTable to make a new sorted table, and then table.sort that sorted table.
If performance is vital, you can greatly speed things up by 'caching' the work done by the sortByValue() iterator. Updated code:
local resort, sorted = true;
local function valueSort(a,b)
return a.value < b.value;
end
function sortByValue( tbl ) -- use as iterator
if not sorted then -- rebuild sorted table
sorted = {};
for i,v in ipairs( tbl ) do sorted[i] = v end;
resort = true;
end
if resort then -- sort the 'sorted' table
table.sort( sorted, valueSort );
resort = false;
end
-- return iterator
return ipairs( sorted );
end
Each time you add or remove an element to/from myTable set sorted = nil. This lets the iterator know it needs to rebuild the sorted table (and also re-sort it).
Each time you update a value property within one of the nested tables, set resort = true. This lets the iterator know it has to do a table.sort.
Now, when you use the iterator, it will try and re-use the previous sorted results from the cached sorted table.
If it can't find the sorted table (eg. on first use of the iterator, or because you set sorted = nil to force a rebuild) it will rebuild it. If it sees it needs to resort (eg. on first use, or if the sorted table was rebuilt, or if you set resort = true) then it will resort the sorted table.
I'm using the LinqToExcel library. Working great so far, except that I need to start the query at a specific row. This is because the excel spreadsheet from the client uses some images and "header" information at the top of the excel file before the data actually starts.
The data itself will be simple to read and is fairly generic, I just need to know how to tell the ExcelQueryFactory to start at a specific row.
I am aware of the WorksheetRange<Company>("B3", "G10") option, but I don't want to specify an ending row, just where to start reading the file.
Using the latest v. of LinqToExcel with C#
I just tried this code and it seemed to work just fine:
var book = new LinqToExcel.ExcelQueryFactory(#"E:\Temporary\Book1.xlsx");
var query =
from row in book.WorksheetRange("A4", "B16384")
select new
{
Name = row["Name"].Cast<string>(),
Age = row["Age"].Cast<int>(),
};
I only got back the rows with data.
I suppose that you already solved this, but maybe for others - looks like you can use
var excel = new ExcelQueryFactory(path);
var allRows = excel.WorksheetNoHeader();
//start from 3rd row (zero-based indexing), length = allRows.Count() or computed range of rows you want
for (int i = 2; i < length; i++)
{
RowNoHeader row = allRows.ElementAtOrDefault(i);
//process the row - access columns as you want - also zero-based indexing
}
Not as simple as specifying some Range("B3", ...), but also the way.
Hope this helps at least somebody ;)
I had tried this, works fine for my scenario.
//get the sheets info
var faceWrksheet = excel.Worksheet(facemechSheetName);
// get the total rows count.
int _faceMechRows = faceWrksheet.Count();
// append with End Range.
var faceMechResult = excel.WorksheetRange<ExcelFaceMech>("A5", "AS" + _faceMechRows.ToString(), SheetName).
Where(i => i.WorkOrder != null).Select(x => x).ToList();
Have you tried WorksheetRange<Company>("B3", "G")
Unforunatly, at this moment and iteration in the LinqToExcel framework, there does not appear to be any way to do this.
To get around this we are requiring the client to have the data to be uploaded in it's own "sheet" within the excel document. The header row at the first row and the data under it. If they want any "meta data" they will need to include this in another sheet. Below is an example from the LinqToExcel documentation on how to query off a specific sheet.
var excel = new ExcelQueryFactory("excelFileName");
var oldCompanies = from c in repo.Worksheet<Company>("US Companies") //worksheet name = 'US Companies'
where c.LaunchDate < new DateTime(1900, 0, 0)
select c;
I'm trying to work with a LINQ result set of 4 tables retrieved with html agility pack. I'd like to process each one slightly differently by setting a variable for each (switch statement below), and then processing the rows within the table. The variable would ideally be the index for each of the tables in the set, 0 to 3, and would be used in the switch statement and to select the rows. I haven't been able to locate the index property, but I see it used in situations such as SelectChildNode.
My question is can I refer to items within a LINQ result set by index? My "ideal scenario" is the last commented out line. Thanks in advance.
var ratingsChgs = from table in htmlDoc.DocumentNode
.SelectNodes("//table[#class='calendar-table']")
.Cast<HtmlNode>()
select table;
String rtgChgType;
for (int ratingsChgTbl = 0; ratingsChgTbl < 4; ratingsChgTbl++)
{
switch (ratingsChgTbl)
{
case 0:
rtgChgType = "Upgrades";
break;
case 1:
rtgChgType = "Downgrades";
break;
case 2:
rtgChgType = "Coverage Initiated";
break;
case 3:
rtgChgType = "Coverage Reit/ Price Tgt Changed";
break;
//This is what I'd like to do.
var tblRowsByChgType = from row in ratingsChgs[ratingsChgTbl]
.SelectNodes("tr")
select row;
//Processing of returned rows.
}
}
ElementAt does what you're asking for. I don't recommend using it in your example, though, because each time you call it, your initial LINQ query will be executed. The easy fix is to have ratingsChgs be a List or Array.
You can also refactor out the switch statement. It is overkill when you only need to iterate through a list of items. Here is a possible solution:
var ratingsChgs = from table in htmlDoc.DocumentNode
.SelectNodes("//table[#class='calendar-table']")
.Cast<HtmlNode>()
select table;
var rtgChgTypeNames = new List
{
"Upgrades",
"Downgrades",
"Coverage Initiated",
"Coverage Reit/ Price Tgt Changed"
};
var changeTypes = ratingsChgs.Zip(rtgChgTypeNames, (changeType, name) => new
{
Name = name,
Rows = changeType.SelectNodes("tr")
});
foreach( var changeType in changeTypes)
{
var name = changeType.Name;
var rows = changeType.Rows;
//Processing of returned rows.
}
Also, why not store your rating change types in the HTML doc? It seems odd to have table information defined in the business logic.
