I'm reading a CSV file and one of the columns has text that contains symbols that is not recognized. After I read the file, symbols such as ' becomes � . I'm also saving this into a DB.
Obviously when I display this on a webpage, it shows garbage. How can I substitute HTML code (ex. ´ ;) for this with Grails?
I am reading the CSV using the csv plugin. Code below:
def f = "clientDocs/testfile.csv"
def fReader = new File(f).toCsvMapReader([batchSize:50, charset:'UTF-8'])
fReader.each { batchList ->
batchList.each {
def description = substituteSymbols(it.Description)
def substituteSymbols(inText) {
// HOW TO SUBSTITUTE HERE
}
Thanks for any help or suggestions. I've already tried string.replaceAll(regExp).
Grails comes with a basic set of encoders/decoders for common tasks.
What you want here is it.Description.encodeAsHTML().
And then if you want the original when displaying in the view, just reverse it with .decodeHTML()
You can read more about these here: http://grails.org/doc/latest/guide/single.html#codecs
(Edited decode method name typo as per the comment)

I've stored a string in the database. When I save and retrieve the string and the result I'm getting is as following:
This is my new object
Testing multiple lines
-- Test 1
-- Test 2
-- Test 3
That is what I get from a println command when I call the save and index methods.
But when I show it on screen. It's being shown like:
This is my object Testing multiple lines -- Test 1 -- Test 2 -- Test 3
Already tried to show it like the following:
${adviceInstance.advice?.encodeAsHTML()}
But still the same thing.
Do I need to replace \n to or something like that? Is there any easier way to show it properly?
Common problems have a variety of solutions
1> could be you that you replace \n with <br>
so either in your controller/service or if you like in gsp:
${adviceInstance.advice?.replace('\n','<br>')}
2> display the content in a read-only textarea
<g:textArea name="something" readonly="true">
${adviceInstance.advice}
</g:textArea>
3> Use the <pre> tag
<pre>
${adviceInstance.advice}
</pre>
4> Use css white-space http://www.w3schools.com/cssref/pr_text_white-space.asp:
<div class="space">
</div>
//css code:
.space {
white-space:pre
}
Also make a note if you have a strict configuration for the storage of such fields that when you submit it via a form, there are additional elements I didn't delve into what it actually was, it may have actually be the return carriages or \r, anyhow explained in comments below. About the good rule to set a setter that trims the element each time it is received. i.e.:
Class Advice {
String advice
static constraints = {
advice(nullable:false, minSize:1, maxSize:255)
}
/*
* In this scenario with a a maxSize value, ensure you
* set your own setter to trim any hidden \r
* that may be posted back as part of the form request
* by end user. Trust me I got to know the hard way.
*/
void setAdvice(String adv) {
advice=adv.trim()
}
}
${raw(adviceInstance.advice?.encodeAsHTML().replace("\n", "<br>"))}
This is how i solve the problem.
Firstly make sure the string contains \n to denote line break.
For example :
String test = "This is first line. \n This is second line";
Then in gsp page use:
${raw(test?.replace("\n", "<br>"))}
The output will be as:
This is first line.
This is second line.
I have so many texts in log file but sometimes i got responses as a xml code and I have to cut this xml code and move to other files.
For example:
sThread1....dsadasdsadsadasdasdasdas.......dasdasdasdadasdasdasdadadsada
important xml code to cut and move to other file: <response><important> 1 </import...></response>
important xml code to other file: <response><important> 2 </important...></response>
sThread2....dsadasdsadsadasdasdasdas.......dasdasdasdadasdasdasdadadsada
Hindrance: xml code starting from difference numbers of sign (not always start in the same number of sign)
Please help me with finding method how to find xml code in text
Right now i tested substring() method but xml code not always start from this same sign :(
EDIT:
I found what I wanted, function which I searched was indexOf().
I needed a number of letter where String "Response is : " ending: so I used:
int positionOfXmlInLine = lineTxt.indexOf("<response")
And after this I can cut string to the end of the line :
def cuttedText = lineTxt.substring(positionOfXmlInLine);
So I have right now only a XML text/code from log file.
Next is a parsing XML value like BDKosher wrote under it.
Hoply that will help someone You guys
You might be able to leverage XmlSlurper for this, assuming your XML is valid enough. The code below will take each line of the log, wrap it in a root element, and parse it. Once parsed, it extracts and prints out the value of the <important> element's value attribute, but instead you could do whatever you need to do with the data:
def input = '''
sThread1..sdadassda..sdadasdsada....sdadasdas...
important code to cut and move to other file: **<response><important value="1"></important></response>**
important code to other file: ****<response><important value="3"></important></response>****
sThread2..dsadasd.s.da.das.d.as.das.d.as.da.sd.a.
'''
def parser = new XmlSlurper()
input.eachLine { line, lineNo ->
def output = parser.parseText("<wrapper>$line</wrapper>")
if (!output.response.isEmpty()) {
println "Line $lineNo is of importance ${output.response.important.#value.text()}"
}
}
This prints out:
Line 2 is of importance 1
Line 3 is of importance 3
I created a custom extension for TYPO3 CMS.
It basically does some database queries to get text from database.
As I have seen, TYPO3 editor, transforms data before storing it in database so for example a link <a href="....." >Link</a> is stored as <link href>My Link Text</link> and so on for many tags like this.
when I query data from DB, I get it as it is stored in DB (<link href>My Link Text</link>)
so links are not displayed as they shoud. They display as normal text..
As far as I know there are two ways to go:
disable RTE transformations (how to do that?)
use lib.parseFunc_RTE (which i have no Idea how to configure it properly)
any idea?
thanks.
I guess you're not using Extbase and Fluid? Just as a reference, if you are using Extbase and Fluid for your extension you can render text from the RTE using Fluid:
<f:format.html>{bodytext}</f:format.html>
This uses lib.parseFunc_RTE to render the RTE text as HTML. You can also tell it to use a different TypoScript object for the rendering:
<f:format.html parseFuncTSPath="lib.my_parseFunc">{bodytext}</f:format.html>
Useful documentation:
parseFunc
Fluid format.html
I came across the same problem, but using EXTBASE the function "pi_RTEcssText" ist not available anymore. Well maybe it is, but I didn't know how to include it.
Anyway, here's my solution using EXTBASE:
$this->cObj = $this->configurationManager->getContentObject();
$bodytext = $this->cObj->parseFunc($bodyTextFromDb, $GLOBALS['TSFE']->tmpl->setup['lib.']['parseFunc_RTE.']);
This way I get the RTE formatted text.
I have managed to do it by configuring the included typoscript:
# Creates persistent ParseFunc setup for non-HTML content. This is recommended to use (as a reference!)
lib.parseFunc {
makelinks = 1
makelinks.http.keep = {$styles.content.links.keep}
makelinks.http.extTarget < lib.parseTarget
makelinks.http.extTarget =
makelinks.http.extTarget.override = {$styles.content.links.extTarget}
makelinks.mailto.keep = path
tags {
link = TEXT
link {
current = 1
typolink.parameter.data = parameters : allParams
typolink.extTarget < lib.parseTarget
typolink.extTarget =
typolink.extTarget.override = {$styles.content.links.extTarget}
typolink.target < lib.parseTarget
typolink.target =
typolink.target.override = {$styles.content.links.target}
parseFunc.constants =1
}
}
allowTags = {$styles.content.links.allowTags}
And denied tag link:
denyTags = link
sword = <span class="csc-sword">|</span>
constants = 1
nonTypoTagStdWrap.HTMLparser = 1
nonTypoTagStdWrap.HTMLparser {
keepNonMatchedTags = 1
htmlSpecialChars = 2
}
}
Well, just so if anyone else runs into this problem,
I found one way to resolve it by using pi_RTEcssText() function inside my extension file:
$outputText=$this->pi_RTEcssText( $value['bodytext'] );
where $value['bodytext'] is the string I get from the database-query in my extension.
This function seems to process data and return the full HTML (links, paragraphs and other tags inculded).
Note:
If you haven't already, it requires to include this file:
require_once(PATH_tslib.'class.tslib_pibase.php');
on the top of your extension file.
That's it basically.
I'm trying to submit a form entry with an uploaded file, but I can't seem to get the controller to save the data properly.
Essentially, I want to post a caption and the uploaded source in one form.
An example of my domain class:
class Image {
String caption
Date dateCreated
Date lastUpated
String source
}
I don't how to store the source file and save the entry.
Here is what I've done so far:
def upload () {
def f = request.getFile('source')
f.transferTo(new File("/path/to/file.tmp"))
return
}
def save () {
upload()
def img = new Image(params)
img.save(flush: true)
...runtime exception...
}
File creation works, but obviously the details on saving the Image entry is incorrect.
Consider this question answered. The problem was not Grails, but the tiny detail of me failing to install the plug-in necessary to insert data into the database.
See this source code Grails file upload example or this presentation Uploading files with Grails.
Hope this helps
I would like to print reports in icefaces, but could got find any proper method for it. Please guide me for implementation of the same in my project.
I've used the ice:outputResource tag to let the user download a PDF report file. The resource attribute of that tag should point a managed bean property that implements com.icesoft.faces.context.Resource.
after getting idea from JOTN I'm finally able to put it together.
We can use the outputresource tag to link to any type of resource, not only static ones but also dynamically generated files(on the fly).
Let us have a look at the following example:
JSF Page:
..
..
<ice:outputResource id="outputResource1" attachment="false" fileName="File1.pdf" label="Click to download attachment" mimeType="application/pdf" rendered="true" resource="#{ReportParam01.reportfilers}" shared="false"/>
..
..
Here I've observed that the outputresource link won't appear until the file is actually generated(i case of on the fly documents).
Let us assume we wish to generate a pdf file dynamically. The following steps will link it to the above mentioned outputrespurce.
Managed Bean:
public class....{
....
// This is the resource linked to the <ice:outputresource> tag.
// Encapsulation has been done to link it.
Reource reportfilers;
....
public void createDocument() {
Document reportDoc = new Document(PageSize.A4);
File file1 = new File("Report.pdf");
PdfWriter.getInstance(reportDoc, new FileOutputStream(f));
// writing to pdf code continues
reportfilers = new FileResource(file1);
}
....
....
}
Calling the above method (if it has no exceptions) will make the link to show up and the user can download the file.
