I have such code:
total_terms = #driver.select_list(:name => 'ctl00$cp$cbRodzajUslugi').length
if (1...5).include?(total_terms)
#driver.select_list(:name => 'ctl00$cp$cbRodzajUslugi').option(:index, total_terms).select
else
#driver.select_list(:name => 'ctl00$cp$cbRodzajUslugi').option(:index, (total_terms-2)).select
end
and I am trying to select some value via index. First, I calculate how long my select_list is, and then I select. But in the browser, I see that nothing is selected. What did I do wrong?
Your code is probably throwing exceptions.
Select lists do not have a method length
The line
#driver.select_list(:name => 'ctl00$cp$cbRodzajUslugi').length
is not valid since select lists do not have a method length. Assuming you want the number of options, need to add the options method to get a collection of options in the select list:
#driver.select_list(:name => 'ctl00$cp$cbRodzajUslugi').options.length
5 or less options selects non-existent option
The line
if (1...5).include?(total_terms)
#driver.select_list(:name => 'ctl00$cp$cbRodzajUslugi').option(:index, total_terms).select
will throw an exception due to there being nothing at the specified index. The :index locator is 0-based - ie 0 means the first option, 1 means the second option, etc. This means that when there are two options, you will try to select :index => 2, which does not exist. You need to subtract 1:
if (1...5).include?(total_terms)
#driver.select_list(:name => 'ctl00$cp$cbRodzajUslugi').option(:index, total_terms-1).select

I am currently working with the Apex Office Print it would be nice if you could help me with two points.
I am creating a template with a lot of fields, and around 50% of
these fields are optional, so they are often only (null) in my
database. Can I do something so that the fields with no value are not
shown?
My second question would be the work with the print function and
checkboxes. How do I integrate the item APEX_APPLICATION.G_F01 so
that I only print the content of a selected checkbox ? It is not
really working in the PL/SQL section.

The {tag} will just be removed when it's empty. In case you want to make some blocks disappear you can wrap that in a condition,
for example:
{#tags=null} {product_name}: {product_description} {/tags=null} {#tags!=null} {product_name}: {tags} {/tags!=null}
or if you have a value:
{#checked=="Yes"}☒Yes ☐No{/checked=="Yes"}{#checked!="Yes"} ☐Yes ☒No {/checked!="Yes"}
My second question would be the work with the print function and checkboxes. How do I integrate the item APEX_APPLICATION.G_F01 so that I only print the content of a selected checkbox ? It is not really working in the PL/SQL section.
Are you running the AOP Process type plugin or the Dynamic Action plugin?
For example we use it for ourself when selecting invoices and printing them.
We have a checkbox in an IR:
apex_item.checkbox2(
p_idx => 1,
p_value => id,
p_attributes => 'class="invoice_id"',
p_checked_values => :P39_INVOICE_ID_LIST,
p_checked_values_delimiter => ',') as chk,
And then we have a Dynamic Action on change that sets an hidden item (P39_INVOICE_ID_LIST) on the page:
var
//Checkbox that was changed
$checkBox = $(this.triggeringElement),
//DOM object for APEX Item that holds list.
apexItemIDList = apex.item(this.affectedElements.get(0)),
//Convert comma list into an array or blank array
//Note: Not sure about the "?" syntax see: http://www.talkapex.com/2009/07/javascript-if-else.html
ids = apexItemIDList.getValue().length === 0 ? [] : apexItemIDList.getValue().split(','),
//Index of current ID. If it's not in array, value will be -1
idIndex = ids.indexOf($checkBox.val())
;
//If box is checked and it doesn't already exist in list
if ($checkBox.is(':checked') && idIndex < 0) {
ids.push($checkBox.val());
}
//If box is unchecked and it exists in list
else if (!$checkBox.is(':checked') && idIndex >= 0){
ids.splice(idIndex, 1);
}
//Convert array back to comma delimited list
apexItemIDList.setValue(ids.join(','));
In our query in the AOP DA we have:
where i.id in (select regexp_substr(:P39_INVOICE_ID_LIST,'[^,]+', 1, level) invoice_id
from dual
connect by regexp_substr(:P39_INVOICE_ID_LIST, '[^,]+', 1, level) is not null)
and we make sure the P39_INVOICE_ID_LIST is set in session state by specifying the Affected Elements of the AOP plugin call.
If you setup an example of what you want to do on apex.oracle.com I'm happy to build you the example there. In AOP 4.0 we will also include an example with checkboxes.
Hope that helps,
Dimitri
I have to modify some old code in an application that someone before me made. Looking at the variable below whose result goes into "test", I have two tables (which are set up with relational models). In the variable "test2", I have rewritten the query in the more SQL syntax (which I'm used to). I want to join on the Lines and Shifts table where the LineId's match. When I view the "test2" output, I get 6 values where the end time is 2-28-2017 8:30, 9:30 ... 1:30, and 2:30. That makes sense. When I view the "test" output, I see one Line with around 500 Shift entries associated to it. Inspecting those elements yields end times that go back to 2017. Should I not get the same 6 entries in the "test" output that I got back in the "test2" output? Is there something that I'm missing behind the scenes that linq is doing different in the "test" output? Any help would be greatly appreciated!
var test = entityFrameworkDateModel.Lines.Where(line => line.Shifts.Any(s => shift.EndTime >= DateTime.Now));
var test2 = from line in entityFrameworkDateModel.Lines
join shift in entityFrameworkDateModel.Shifts on line.LineID equals shift.LineId
where shift.EndTime >= DateTime.Now
select new
{
line.LineID,
shift.EndTime
};
test is a collection of Line objects that has 0 to many Shift objects. I would expect that
test.SelectMany(t => t.Shifts).Count() == 500 // approx. 500 anyways
test2 is a collection of AnonymousObjects. test2 is flattening your data with one object per LineId / Shift End Time pair. Where as test is keeping your data in a hierarchy.
Inspecting those elements yields end times that go back to 2017.
Test can and will contain shifts that are not matching your where criteria. Since you are only returning Line objects that have shifts with an end time greater than now. So your Line object will have 1 or more shifts matching EndTime >= DateTime.Now. But the .Any() does not filter out the other Shift objects Where EndTime < DateTime.Now.
You can add a SelectMany then Where to return all Shift objects matching your criteria:
var test = entityFrameworkDateModel.Lines
.SelectMany(line => line.Shifts)
.Where(shift => shift.EndTime >= DateTime.Now);
Those 2 are not the same, even though they feel similar. For the first query, the nested "any" filtering isn't needed. The "where" alone is enough. The any is actually going to return just true, which will short circuit the where. I'd lay out the correct syntax for the where clause, but I'm on mobile SO and can't see the question while I'm answering
I need to make query (in search model) where:
Get current row index (not id)
Do a manipulation with that count (multiply this on constant number) and add if condition (if 'row index' > 10)
See this count in the model
Some steps I resolve:
I know how to create 'new column' and see it in the gridview:
$query->select([
'{{tour}}.*',
'(1000 / 'need to add row index' ) as points' //$points
]);
I know how to get a current index, but with active record:
MyModel::find()->andFilterWhere(['>=', 'cumulative_points', $playerPoints])->count();
But I need to combine this query. Anybody can help me?
Thanks.
When you need you can express the content of SQL part like literal and then assign the select content you prefer (not using array / hash assignment) this way
$query->select(' tour.*, 1000 / id ) as points' )
Sostantially you can assign to activeQuery select() method exactly the select part of you query ..

I am working on a ruby on rails site and I want to check its database for which is the most frequent name among the registered users.
There is a row called "First Name" for which I will go through. I don't mind about case sensitive right now.
Any convenient way to for example check what is the most popular name and then the second most popular, the third most popular and so on?
What I thought of is to get all users in an array and then do #users.each do |user|, then record the names in an array and after that to count the duplicates of each record that has more than one element recorded. I am not sure if its the proper way though.
Here is how you can do it using ActiveRecord:
User.group(:first_name).order('popularity desc').pluck(:first_name, 'count(*) as popularity')
This code translates to the SQL:
SELECT "users.first_name", count(*) as popularity FROM "users"
GROUP BY first_name
ORDER BY popularity
and you get something like:
[["John", 2345], ["James", 1986], ["Sam", 1835], ...]
If you want only the top ten names, you can limit the number of results simply by adding limit:
User.group(:first_name).order('popularity desc').limit(10).pluck(:first_name, 'count(*) as popularity')
Another option is to use the count API:
User.group(:first_name).count
=> {"Sam" => 1835, "Stefanos" => 2, ...}
# ordered
User.group(:first_name).order('count_all desc').count
=> {"John" => 2345, "James" => 1986, "Sam" => 1835, ...}
# top 3
User.group(:first_name).order('count_all desc').limit(3).count
=> {"John" => 2345, "James" => 1986, "Sam" => 1835 }
You could do the following SQL statement
select count(*) as count from users group by users.first_name order by count desc
Will return you the top most results. As Boris said, using just sql is the right way to go here.
Otherwise if you want to load all the users, you could do so by map-reduce.
#users.group_by(&:first_name).sort(&:count).reverse
Will give you an array of users sorted descending by their names.
Another way using ActiveRecord:
User.group(:first_name).count
Generated SQL is:
SELECT COUNT(*) AS count_all, name AS name FROM `users` GROUP BY name
Will output a hash of { name => number_of_occurances } e.g
{"John" => 29, "Peter" => 87, "Sarah" => 2}
I am building a financial reporting app with Ruby on Rails. In the app I have monthly financial statement objects (with 'revenue' as an attribute). For any single financial statement, I want show (1) year-to-date revenue, and (2) last-year-to-date revenue (calendar years are fine). Each object also has a Date (not Datetime) attribute called 'month' (watch out for 'month' variable name vs. 'month' method name confusion...maybe I should change that variable name).
So...
I think I need to (1) 'find' the array of financial statements (i.e., objects) in the appropriate date range, then (2) sum the 'revenue' fields. My code so far is...
def ytd_revenue
# Get all financial_statements for year-to-date.
financial_statements_ytd = self.company.financial_statements.find(:all,
:conditions => ["month BETWEEN ? and ?", "self.month.year AND month.month = 1",
"self.month.year AND self.month.month" ])
# Sum the 'revenue' attribute
financial_statements_ytd.inject(0) {|sum, revenue| sum + revenue }
end
This does not break the app, but returns '0' which cannot be correct.
Any ideas or help would be appreciated!
This statement may do what you want:
financial_statements_ytd.inject(0) {|sum, statement| sum + statement.revenue }
You can also look into ActiveRecord's sum class method - you can pass in the field name and conditions to get the sum.
What is the name of the field in financial_statement object that holds the value you want?
Supposing that the field name is ammount then just modify the inject statement to be:
financial_statements_ytd.inject {|sum, revenue| sum + revenue.ammount }
