As part of moving from a windows server to a linux server I have to clean up a large number of filenames.
My Problem is that when I execute:
db_query("UPDATE {files} SET filename = '%s' AND filepath = '%s' WHERE fid = %d", $file->filename, $file->filepath, $file->fid);
and afterwards select the content for $file->fid the filename field has the value of "0"
If I dump the query as text both before and after it's being executed the filename field contains the filename I have specified where as the filepath is being stored correctly.
DAMN! putting an AND into an update query will not produce the expected result... MySQL allows this but it's not the way to go :)
Use a comma instead of AND.
Might also want to look into using drupal_write_record() instead of db_query. drupal_write_record will automatically update a pre-existing row if you add the 3rd parameter for a key to check. In your case, you could use the file id.

I want to copy an Excel file to a different path through Matlab and then write in it also using Matlab. Somehow I get the error: Name cannot be the same as built-in name.
As I want to write multiple times in the file, I don't want to solve this problem manuelly each time, I want the code to run through without me having to do something constantly.
Is there any way I can solve this problem all at once through code? Does this happen because I copy the Excel file first?
The code looks like this:
path_source_template1 = 'Blabla1\Template1.xlsx';
timestamp = datestr(now);
timestamp = strrep(timestamp, ':', '-');
timestamp = strrep(timestamp, ' ', '-');
path_output = fullfile('Blabla2\',timestamp);
mkdir(fullfile(path_output));
path_output_template1 = strcat(path_output,'\Template1.xlsx');
copyfile(path_source_template1,path_output_template1);
Then I want to write in the Template1.xlsx:
writematrix(test,path_output_template1,'Sheet','Test','Range','A1',UseExcel=true,AutoFitWidth=false);
Then I get this error:
enter image description here
The input to the writematrix file uses the name, value format, so in this line:
writematrix(test,path_output_template1,'Sheet','Test','Range','A1',UseExcel=true,AutoFitWidth=false);
you should have:
..., 'Sheet','Test','Range','A1','UseExcel', true,'AutoFitWidth', false);
Disclaimer: I haven't tested this, but I'm fairly certain this will fix your problem.
The correct call to the writematrix would be:
writematrix(test,path_output_template1, 'Sheet','Test','Range','A1', 'UseExcel', true,'AutoFitWidth',false);
When writing datetime data to a spreadsheet file, you must set both 'PreserveFormat' and the 'UseExcel' Name-Value pair to true to preserve the existing cell formatting. You can check the documentation writematrix.
In order to answer to the error I tested the code locally in Matlab 2019b and works well setting the test variable in this example way: test = magic(5);.
Maybe the error could be in the data that you use in test variable or in that if you run the code iteratively very fast the path_output could exist, One way to improve this could be with a more accurate timestamp.
I am basically trying to save to data/${EPOCH_TIME}:
begin_unix_time: "J"$first system "date +%s"
\t:1 save `data/"string"$"begin_unix_time"
I am expecting it to save to data/1578377178
You do not need to cast first system "date +%s" to a long in this case, since you want to attach one string to another. Instead you can use
begin_unix_time:first system "date +%s"
to store the string of numbers:
q)begin_unix_time
"1578377547"
q)`$"data/",begin_unix_time
`data/1578377547
Here you use the comma , to join one string to another, then using cast `$ to convert the string to a symbol.
The keyword save is saving global data to a file. Given your filepath, it looks like youre trying to save down a global variable named 1578377547, and kdb can not handle variable names being purely numbers.
You might want to try saving a variable named a1578377547 instead, for example. This would change the above line to
q)`$"data/a",begin_unix_time
`data/a1578377547
and your save would work correctly, given that the global variable a1578377547 exists. Because you are sourcing the date down to the second from linux directly in the line you are saving a variable down to, this will likely not work, due to time constantly changing!
Also note that the timer system command will repeat it the execution n times (as in \t:n), meaning that the same variable will save down mutliple times given the second does not change. The time will also likely change for large n and you wont have anything assigned to the global variable you are trying to save should the second change.
I am dynamically displaying sermons from a MYSQL database, and I want to create a dynamic page for each sermon series. Because the series titles have spaces in them, and I want to avoid that in my URLs, I have done str_replace:
(Series name)
That works great. But then of course on the dynamically-created page, I need a way to revert back to the original series name in order to fetch the actual sermon data, and I haven't figured out to how to accomplish that. I've tried this:
$series = $_GET['series'];
$str = $series;
$str = str_replace("-"," ",$str);
... ahead of my prepare & execute statements (I'm using PDO), but that doesn't really look right, and in any case doesn't work.
Is there actually a way to this?
I just needed to change one variable. The lead variable of the third line needed to be $series, not $str:
$series = $_GET['series'];
$str = $series;
$series = str_replace("-"," ",$str);
Suppose I have a file named test.txt and it currently has the number 6 inside of it. I want to use a variable such as x=4 then write to the file and add the two numbers together and save the result in the file.
var1 = 4.0
f=open(test.txt)
balancedata = f.read()
newbalance = float(balancedata) + float(var1)
f.write(newbalance)
print(newbalance)
f.close()
It's probably simpler than you're trying to make it:
variable = 4.0
with open('test.txt') as input_handle:
balance = float(input_handle.read()) + variable
with open('test.txt', 'w') as output_handle:
print(balance, file=output_handle)
Make sure 'test.txt' exists before you run this code and has a number in it, e.g. 0.0 -- you can also modify the code to deal with creating the file in the first place if it's not already there.
Files only read and write strings (or bytes for files opened in binary mode). You need to convert your float to a string before you can write it to your file.
Probably str(newbalance) is what you want, though you could customize how it appears using format if you want. For instance, you could round the number to two decimal places using format(newbalance, '.2f').
Also note that you can't write to a file opened only for reading, so you probably need to either use mode 'r+' (which allows both reading and writing) combined with a f.seek(0) call (and maybe f.truncate() if the length of the new numeric string might be shorter than the old length), or close the file and reopen it in 'w' mode (which will truncate the file for you).
I am running cygwin on Windows 7. I am using a signal processing tool and basically performing alignments. I had about 1200 input files. Each file is of the format given below.
input_file_ format = "AC_XXXXXX.abc"
The first step required building some kind of indexes for all the input files, this was done with the tool's build-index command and now each file had 6 indexes associated with it. Therefore now I have about 1200*6 = 7200 index files. The indexes are of the form given below.
indexes_format = "AC_XXXXXX.abc.1",
"AC_XXXXXX.abc.2",
"AC_XXXXXX.abc.3",
"AC_XXXXXX.abc.4",
"AC_XXXXXX.abc.rev.1",
"AC_XXXXXX.abc.rev.1"
Now, I need to use these indexes to perform the alignment. All the 6 indexes of each file are called together and the final operation is done as follows.
signal-processing-tool ..\path-to-indexes\AC_XXXXXX.abc ..\Query file
Where AC_XXXXXX.abc is the index associated with that particular index file. All 6 index files are called with **AC_XXXXXX.abc*.
My problem is that I need to use only the first 14 characters of the index file names for the final operation.
When I use the code below, the alignment is not executed.
for file in indexes/*; do ./tool $file|cut -b1-14 Project/query_file; done
I'd appreciate help with this!
First of all, keep in mind that $file will always start with "indexes/", so trimming first 14 characters would always include that folder name in the beginning.
To use first 14 characters in a variable, use ${file:0:14}, where 0 is the starting string index, and 14 is the length of the desired substring.
Alternatively, if you want to use cut, you need to run it in a subshell: for file in indexes/*; do ./tool $(echo $file|cut -c 1-14) Project/query_file; done I changed the arg for cut to -c for characters instead of bytes
