I am trying to use a script from https://gist.github.com/jexp/0617412dcdd644fd520b. There is no authors.csv file, so I created my own test file that has 3 columns: author, title and date. Then I tried to run the groovy script and got the following error
Caught: groovy.lang.MissingPropertyException: author
groovy.lang.MissingPropertyException: author
at com.xlson.groovycsv.PropertyMapper.propertyMissing(PropertyMapper.groovy:52)
at test.run(test.groovy:55)
I don't know Java and I am wondering if someone can point what happened here.
[I was running the first script that uses only 1 input file]
Added explanation. My CSV file looks like this
author title date
Auth1 Title1 date1
... ... ...
You will need to add a header line to your CSV:
author,date,title
(Assuming that's the order in your CSV)
I faced the same issue with groovyCSV 7 years later...
The answer comes probably too late for you, but maybe it will help someone else.
In my case I was able to call every other column without any problem, but calling the first one always returned a MissingPropertyException exception.
Problem was that I created my csv file with Excel and this stupid software adds a BOM (byte order mark) at the beginning of the csv files, which prevented groovyCSV from reading correctly the header value of the first column.
Cleaning the csv file with a dos2unix command fixed the problem.

I am trying to get my program to write over a simple config.txt file.
Which is actually working: it writes the new content over the old one if one condition is met and proceeds to the next block.
However, when the next block calls another function of my program, the content of the file simply dissapears: the .txt file becomes empty.
I have searched SO for similar issues but couldn't find any posts.
I looked into:
How to search and replace text in a file using Python?
Search and replace a line in a file in Python
And and got some of these to work but always ran into the issue above.
Please be gentle as I am a newbie and this is my first "not Hello_world" program and my first post. Thanks:)
>>>Content of the default config.txt file is 'runcount=0'
def alias(confirmation):
###First block###
if confirmation.lower()=='yes':
print("...")
config=open('config.txt','r')
data=config.read()
config.close()
newdata=data.replace('runcount=0','runcount=1')
config=open('config.txt','w')
config.write(newdata)
config.close()
confirmation2=input()
>>>Content of the config.txt file is now 'runcount=1'
###Second block###
if confirmation2.lower()=='yes':
print("...")
return main()
else:
...
>>>The main() function is called... However the config.txt file is now empty
I choose to show you this code because I think it is the most readable.
I tried the "with" method which gives me the same results.
I also tried to write to a new file, remove the default and rename the new to config.txt... same issue.
I don't get why the file becomes empty as I closed it.
No error msg, my program just goes on but the file is empty.
Please note that I used open(config.txt, 'r') in another function of my program, only once yet.
It happens that I coded the following line in main() and did not close config.txt:
config=open("config.txt","w+")
And forgot about it...
Thank you guys for the hint.
I'm going to hide somewhere very dark now.
I'm trying to Create a file and append all the content being calculated into that file, but when I run the script the very last iteration is written inside the file and nothing else.
My code is on pastebin, it's too long, and I feel like you would have to see exactly how the iteration is happening.
Try to summarize it, Go through an array of model numbers, if the model number matches call the function that calculates that MAC_ADDRESS, when done calculating store all the content inside a the file.
I have tried two possible routes and both have failed, giving the same result. There is no error in the code (it runs) but it just doesn't store the content into the file properly there should be 97 different APs and it's storing only 1.
The difference between the first and second attempt,
1 attempt) I open/create file in the beginning of the script and close at the very end.
2 attempt) I open/create file and close per-iteration.
First Attempt:
https://pastebin.com/jCpLGMCK
#Beginning of code
File = open("All_Possibilities.txt", "a+")
#End of code
File.close()
Second Attempt:
https://pastebin.com/cVrXQaAT
#Per function
File = open("All_Possibilities.txt", "a+")
#per function
File.close()
If I'm not suppose to reference other websites, please let me know and I'll just paste the code in his post.
Rather than close(), please use with:
with open('All_Possibilities.txt', 'a') as file_out:
file_out.write('some text\n')
The documentation explains that you don't need + to append writes to a file.
You may want to add some debugging console print() statements, or use a debugger like pdb, to verify that the write() statement actually ran, and that the variable you were writing actually contained the text you thought it did.
You have several loops that could be a one-liner using readlines().
Please do this:
$ pip install flake8
$ flake8 *.py
That is, please run the flake8 lint utility against your source code,
and follow the advice that it offers you.
In particular, it would be much better to name your identifier file than to name it File.
The initial capital letter means something to humans reading your code -- it is
used when naming classes, rather than local variables. Good luck!
When I run the following code:
f = new File(projectroot + "/outputTest1.csv")
f.append("hello world" + '\n')
Here is the result in csv file:
hello world
hello world
Why is it displaying a duplicate?
Take note: I'm using groovy in soapUI
Append adds given string to the end of the file, so when you run it for the third time, it should display 3 hello worlds.
Two possible explanations there :
You're not clearing the file content before writing to it, which means you'll add a new line with "Hello world" every time you execute your code. Either :
use the "Write" method instead of "Append"
clear the file using file.bytes = new byte[0]
You call this piece of code twice, which can be checked by adding a log/display and checking if your log only appears once.

Groovy documentation about file handling
I was using this code inside of an assertion of SoapUI then created duplicate. When I added a separate groovy step with the same code then it worked correctly.
I have the current problem that many of my employees in Hybris have the HMC login attribute set to inherit from group, which means that they can't log in to the HMC. This was due to that I used an impex script that set new users to this a while ago. I try now to write an impex script that updates all employees to have HMC access instead. I found the <ignore> tag to be interesting on the Wiki which states that "There is a special value that makes the ImpEx skip the entry and leave the item value at the one it currently is." (https://wiki.hybris.com/display/release4/ImpEx+Syntax). So when I am trying to use the following script:
UPDATE Employee;UID[unique=true];password;description;name;groups(uid);sessionLanguage(isocode);sessionCurrency(isocode);hmcLoginDisabled[default=false]
;<ignore>;<ignore>;<ignore>;<ignore>;<ignore>;<ignore>;<ignore>
I think it should ignore all current values and set hmcLoginDisabled to false. But HAC gives me the following output:
UPDATE Employee;UID[unique=true];password;description;name;groups(uid);sessionLanguage(isocode);sessionCurrency(isocode);hmcLoginDisabled[default=false]
,,no existing item found for update;<ignore>;<ignore>;<ignore>;<ignore>;<ignore>;<ignore>;<ignore>
27.03.2014 15:26:38: ERROR: line 3 at main script: Can not resolve any more lines ... Aborting further passes (at pass 2). Finally could not import 1 lines!
27.03.2014 15:26:38: ERROR: line 3 at main script: Can not resolve any more lines ... Aborting further passes (at pass 2). Finally could not import 1 lines!
Anyone that has any idea on how to write an impex script to solve this?
Just considered Nevins post and came up with this final solution that actually worked:
UPDATE Employee[batchmode=true];itemtype(code)[unique=true];hmcLoginDisabled[default=false]
;Employee
You can just leave the fields blank if you don't want to update the value.
I have another puzzling problem.
I need to read .xls files with RODBC. Basically I need a matrix of all the cells in one sheet, and then use greps and strsplits etc to get the data out. As each sheet contains multiple tables in different order, and some text fields with other options inbetween, I need something that functions like readLines(), but then for excel sheets. I believe RODBC the best way to do that.
The core of my code is following function :
.read.info.default <- function(file,sheet){
fc <- odbcConnectExcel(file) # file connection
tryCatch({
x <- sqlFetch(fc,
sqtable=sheet,
as.is=TRUE,
colnames=FALSE,
rownames=FALSE
)
},
error = function(e) {stop(e)},
finally=close(fc)
)
return(x)
}
Yet, whatever I tried, it always takes the first row of the mentioned sheet as the variable names of the returned data frame. No clue how to get that solved. According to the documentation, colnames=FALSE should prevent that.
I'd like to avoid the xlsReadWrite package. Edit : and the gdata package. Client doesn't have Perl on the system and won't install it.
Edit:
I gave up and went with read.xls() from the xlsReadWrite package. Apart from the name problem, it turned out RODBC can't really read cells with special signs like slashes. A date in the format "dd/mm/yyyy" just gave NA.
Looking at the source code of sqlFetch, sqlQuery and sqlGetResults, I realized the problem is more than likely in the drivers. Somehow the first line of the sheet is seen as some column feature instead of an ordinary cell. So instead of colnames, they're equivalent to DB field names. And that's an option you can't set...
Can you use the Perl-based solution in the gdata instead? That happens to be portable too...
