I want to add multiple conditions to a breakpoint in IntelliJ.
Something like:
stringA.equals("test") && objectA.equals(objectB);
How can I do this?
IntelliJ IDEA breakpoint condition can be any boolean expression:
Select to specify a condition for hitting a breakpoint. A condition is
a Java Boolean expression including a method returning true or false,
for example, str1.equals(str2).
This expression must be valid at the line where the breakpoint is set,
and it is evaluated each time the breakpoint is hit. If the evaluation
result is true, the selected actions are performed.
You can enter multi-line expressions, for example:
if (myvar == expectedVariable) {
System.out.println(myvar);
anotherVariable = true;
}
return true;
stringA.equals("test") && objectA.equals(objectB) appears to be a valid expression returning true or false, so it should work right out of the box.
Proof of work:
The following condition statement will also work:
return stringA.equals("test") && objectA.equals(objectB);
Please note that there is a known issue which will show a red underline after the condition indicating that semicolon is expected. If you add the semicolon, the condition will become invalid and you will have to also add a return statement to make it valid again. It's a cosmetic issue and you can either use the condition without semicolon and ignore the error or you can add the semicolon and return to make it a valid statement:
So adding a return statment in front of the statment solved the problem.

So I have a string from a rendered template that looks like
"Dear {{user_name}},\r\n\r\nThank you for your purchase. If you have any questions, we are happy to help.\r\n\r\n\r\n{{company_name}}\r\n{{company_phone_number}}\r\n"
All those variables like {{user_name}} are optional and do not need to be included but I want to check that if they are, they have {{ in front of the variable name. I am using liquid to parse and render the template and couldn't get it to catch if the user only uses 1 (or no) opening brackets. I was only able to catch the proper number of closing brackets. So I wrote a method to check that if these variables exist, they have the correct opening brackets. It only works, however, if all those variables are found.
here is my method:
def validate_opening_brackets?(template)
text = %w(user_name company_name company_phone_number)
text.all? do |variable|
next unless template.include? variable
template.include? "{{#{variable}"
end
end
It works, but only if all variables are present. If, for example, the template created by the user does not include user_name, then it will return false. I've also done this loop using each, and creating a variable outside of the block that I assign false if the conditions are not met. I would really, however, like to get this to work using the all? method, as I can just return a boolean and it's cleaner.
If the question is about how to rewrite the all? block to make it return true if all present variable names have two brackets before them and false otherwise then you could use something like this:
def validate_opening_brackets?(template)
variables = %w(user_name company_name company_phone_number)
variables.all? do |variable|
!template.include?(variable) || template.include?("{{#{variable}")
end
end
TL;DR
There are multiple ways to do this, but the easiest way I can think of is to simply prefix/postfix a regular expression with the escaped characters used by Mustache/Liquid, and using alternation to check for each of your variable names within the template variable characters (e.g. double curly braces). You can then use String#scan and then return a Boolean from Enumerable#any? based on the contents of the Array returned by from #scan.
This works with your posted example, but there may certainly be other use cases where you need a more complex solution. YMMV.
Example Code
This solution escapes the leading and trailing { and } characters to avoid having them treated as special characters, and then interpolates the variable names with | for alternation. It returns a Boolean depending on whether templated variables are found.
def template_string_has_interpolations? str
var_names = %w[user_name company_name company_phone_number]
regexp = /\{\{#{var_names.join ?|}\}\}/
str.scan(regexp).any?
end
Tested Examples
template_string_has_interpolations? "Dear {{user_name}},\r\n\r\nThank you for your purchase. If you have any questions, we are happy to help.\r\n\r\n\r\n{{company_name}}\r\n{{company_phone_number}}\r\n"
#=> true
template_string_has_interpolations? "Dear Customer,\r\n\r\nThank you for your purchase. If you have any questions, we are happy to help.\r\n\r\n\r\nCompany, Inc.\r\n(555) 555-5555\r\n"
#=> false
I'm trying to create a function, it exists and does not exist in the search feature. Condition does not exist, will display Error 404. Condition, exists. Then it will display from search. But in the code I wrote, it only shows Error 404.
This is my model:
function search_album($keyword){
$result=$this->db->query("SELECT tbl_album.*,DATE_FORMAT(album_date,'%d %M %Y') AS date FROM tbl_album WHERE album_title LIKE '%$keyword%'");
return $result;
}
This is my controller:
function search(){
$keyword=str_replace("'", "", $this->input->post('xfilter',TRUE));
$x['data']=$this->model_album->search_album($keyword);
if(empty($x) && empty($keyword)){
$this->load->view('view_contents',$x);
}
else if (!empty($x) && !empty($keyword)){
$this->load->view('view_error_404');
}
}
I've tried from this source, but it doesn't work. Can you help me?
There are several errors in your code:
ONE: You have interchanged your if statements. Like, if the search did not return any data and the keyword was not supplied, it is supposed to display the "view_error_404", otherwise, it is supposed to load data into the view "view_contents".You did the vice versa I have corrected that for you in the code below.
TWO: You are checking if $x is empty which will never be empty as you have initialized $x['data']. Note that the model can return empty data, such that $x['data'] is empty. Instead, check if the search result is empty by replacing empty($x) with empty($x['data'])
THREE: In your model, you are returning the query builder class, but not the actual data from the query statement. instead, replace return $result; with return $result->result();
FOUR:
From your if statements, you need to add an else statement so that if the 2 conditions are never met, it can execute. With your current implementation, there is a state which will not meet first or second conditions and will lead to a blank screen.
if(empty($x['data']) && empty($keyword)){
$this->load->view('view_error_404');
}else if (!empty($x['data']) && !empty($keyword)){
$this->load->view('view_contents',$x);
}else{
$this->load->view('view_error_404'); // replace this code with your preference
}
you need to mention search function in routes.php file like this:-
$routes['search'] ='your_controller_name/search';
without knowing your function model_album->search_album($keyword) and assuming it returns a string or array, you don't need to worry about checking for the keyword, since without a keyword the function should return false or empty.
anyway you mixed up your if/else conditions, since you are checking for not empty results to return a 404, instead of empty result returning the 404.
this should do it:
if(empty($x)){
$this->load->view('view_error_404');
}
else {
$this->load->view('view_contents',$x);
}
I need the "elabora prenotazione" button to be shown only when the column "stato prenotazione" is "IN SOSPESO"
I tried to set a condition but I don't know how to pick the column value
If I understand your question, this could help:
For the source of your report:
SELECT
CASE
WHEN stato_prenotazione = 'in sospeso' THEN 'elabora prenotazione'
ELSE ''
END name_of_column,
prenotazione,
username,
nome,
cognome,
viaggio,
stato_viaggio,
data_prenota,
stato_prenotazione,
numero_ospiti
FROM your_table
Then set the column "name_of_column" to type: link, and fill the target.
Wrap a condition around a call to apex_page.get_url within your SQL, so it will only produce a link when relevant
Example of function in use, sans condition:

Use this to make the button look prettier, and maybe get some other ideas
https://www.grassroots-oracle.com/2015/12/tutorial-include-action-button-in-report.html
See this in regard to escaping special characters, otherwise you'll just see HTML in your report
https://www.grassroots-oracle.com/2017/01/escape-special-characters-apex-demo.html
This could be resolved by a simple case statement as #sara mentioned.
something like:
select (case stato_prenotazione when 'in sospeso' then 'elabora prenotazione' end) as your_column
I would not keep else condition so that the column will simply contain null value if the condition is not met.
I can't seem to find a solution to this.
I'm trying to nest a if statement inside a for loop in Jade engine (using express js).
The base code is shown below:
form
select
for obj, i in phoneModel
option(value='#{i}') #{obj.phone_model}
What I would like to do is to have a IF statement inside the for loop to check to see if a varaible "deviceIndex" is a certain value. Eg. If deviceIndex == i, then do something, else do some other thing.
I have tried the code below:
form
select
for obj, i in phoneModel
- if(phoneIndex == #{i})
option(value='#{i}') #{obj.phone_model}
- else
option(value='#{i}' selected='selected') #{obj.phone_model}
It gives the "expect indent, but got newline" error. I expect it is my placement of the if statement inside the for loop; however, I have tried just about every combination of tabs and spaces as well as putting the "option(val..." line inside a bracket on the same line as the if statement.
What's with the typeof around a boolean? And shouldn't the phone with phoneIndex == i be the one selected? Also, the point of Jade is to have much cleaner code. Tell me if this works:
form
select
for obj, i in phoneModel
option(value=i, selected=phoneIndex==i)= obj.phone_model
I have the following linq query:
var test = vendorContact.vendorContactItem
.Where(x => x.ItemNumber == vendorContactItem.Item_Number)
.FirstOrDefault();
It fails on this piece of code, "Value cannot be null, parameter name: source" ... yet it also displays, in the local variables window, "test" as a variable with all its properties populated.
vendorContact.VendorContactItem is null. Presumably this would be the first element to be added to the list. So how is "test" evaluating correctly while simultaneously throwing up that error?
I'm new to Linq, so excuse me if this is an obvious question.
If this is in a loop test in the locals window contains the last value of test, from the last iteration of the loop.
Edit: This has really nothing to do with LINQ, but how the debugger works.
