I'm trying to use a groovy Config entry to parse an xml file with XmlSlurper.
Here's the Config file:
sample {
xml {
frompath = "Email.From"
}
}
Here's the XML
<xml>
<Email>
<From>
<Address>foo#bar.com</Address>
<Alias>Foo Bar</Alias>
</From>
<Email>
</xml>
This is what I tried initially:
XmlSlurper slurper = new XmlSlurper()
def record = slurper.parseText((new File("myfile.xml")).text)
def emailFrom = record?."${grailsApplication.config.sample.xml.frompath}".Address.text()
This doesn't work because XmlSlurper allows one to use special characters in path names as long as they're surrounded by quotes, so the app is translating this as:
def emailFrom = record?."Email.From".Address.text()
and not
def emailFrom = record?.Email.From.Address.text()
I tried setting the frompath property to be "Email"."From" and then '"Email"."From"'. I tried tokenizing the property in the middle of the parse statement (don't ask.)
Can someone please point me towards some resources to find out if/how I can do this?
I feel like this issue getting dynamic Config parameter in Grails taglib and this https://softnoise.wordpress.com/2013/07/29/grails-injecting-config-parameters/ may have whispers of a solution, but I need fresh eyes to see it.
The solution in issue getting dynamic Config parameter in Grails taglib is a proper way to deref down such a path. E.g.
def emailFrom = 'Email.From'.tokenize('.').inject(record){ r,it -> r."$it" }
def emailFromAddress = emailFrom.Address.text()
If your path there can get complex and you rather go with the potentially more dangerous way, you could also use Eval. E.g.
def path = "a[0].b.c"
def map = [a:[[b:[c:666]]]] // dummy map, same as xmlslurper
assert Eval.x(map, "x.$path") == 666

I have following mapping defined
def e_environments = [["demo1#mystuff.com":"file1"], ["demo2#mystuff.com":"file1"], ["insurance1#mystuff.com":"file2"], ["insurance2#mystuff.com":"file2"]]
Is there a way to replace URL's with same file name from a variable value. For example
def demo_env = ["demo1#mystuff.com","demo2#mystuff.com"]
def insurance_env= ["insurance1#mystuff.com","insurance2#mystuff.com"]
def def e_environments = [[${demo_env}:"file1"], [${insurance_env}:"file2"]]
I hope you must have made some efforts from your side before asking here.
Here is something for you to work upon,
def e_environments = [ "demo1#mystuff.com":"file1", "demo2#mystuff.com":"file1" , "insurance1#mystuff.com":"file2" ,"insurance2#mystuff.com":"file2" ]
def temp = []
e_environments.keySet().each{
temp.add(e_environments[it])
}
temp.unique().each{ val ->
println e_environments.findAll{it.value==val}
}
Got all keys from Map
Created a unique list of it
And a little bit of groovy magic for you to fix and figure it out.
I have got a file with name "silent.txt". This file is having a line as follows
bop4InstallDir = myProps.cordys_install_dir + "/" + instanceName
I want to replace the above text with
bop4InstallDir = "/abc/xyz/pqr"
Using groovy script how do I accomplish this?
Please help.
Not very elegant, but this should work.
def file = new File("silent.txt")
file.text = file.text.replace('bop4InstallDir = myProps.cordys_install_dir + "/" + instanceName',
'bop4InstallDir = "/abc/xyz/pqr"')
Is silent.txt well formatted property file? In this case you can use a various ways to access them, much more secure, than dumb replace.
Look groovy: How to access to properties file?
or ConfigSlurper
The following code worked:
def file = new File("silent.txt")
def fileText = file.replaceAll("bop4InstallDir\\ \\=\\ myProps.cordys_install_dir\\ \\+\\ \"\\/\"\\ \\+\\ instanceName", "bop4InstallDir\\ \\=\\ \"/opt/cordys/bop4/defaultInst1\"")
file.write(fileText);
I need to translate a message key using a Hashmap using the Grails standard internationalization method.
I receive an Enum and a map with the binding, which are going to be replaced in the text.
The Enum indicates, which key is going to be recovered. The bindings have the values to replace on the translation.
messageSource.getMessage("mail.layout.subject.${templateName}",ARGS,"",locale)
The problem is that I need to pass the map to the args like an array, not like a map, but I don't know the order of the args.
My question is, if there are any ways to create a tranlation key like:
mail.layout.subject.ENUM1=Blablabl {name} bablablabl {age}
Instead of
mail.layout.subject.ENUM1=Blablabl {0} bablablabl {1}
Finally I did it with brute force. May be is not the best answer but I coudln't find any one better.
Basically I get the translation with te message resources and then I work with it finding my custom expresions.
def messageSource = grailsApplication.getMainContext().getBean('messageSource')
def subject = messageSource.getMessage("mail.layout.subject.NOTIFICATION",null,"",locale)
An example of subject resource
mail.layout.subject.NOTIFICATION=The user {friend.name} is friend of {user}
An example bindings:
def bindings = [friend:[name:"Jhon",surname:"Smith"],user:"David"]
With this senteces I replace my expresions with the value of the bindings
Pattern pattern = Pattern.compile("\\{[^}]+\\}")
def res = subject.replaceAll(pattern,{
def expresion = it[1..it.size()-2] // removes brackets
def fields = expresion.split("\\.");
def res = bindings
fields.each{
println(it)
res = res."${it}"
}
return res
})
After the proces the subject becomes like: "The user Jhon is friend of David"
The example use a HashMap of HashMaps, but it also works with object because grails/groovy handles the object like HashMaps and viceversa
This is much cleaner. :)
import groovy.text.SimpleTemplateEngine
def text = 'Dear "$firstname $lastname",So nice to meet you in ${city.name}.See you in ${month},${signed}'
def binding = ["firstname":"Sam", "lastname":"Pullara", "city":["name":"San Francisco", "id":"28"], "month":"December", "signed":"Groovy-Dev"]
def engine = new SimpleTemplateEngine()
template = engine.createTemplate(text).make(binding)
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 looked around but could not find a way of simply including or rendering *.html files in Grails. My application needs to g.render or <g:render> templates which are delivered as html files. For this, as we know, html files have to be converted to _foo.gsp files in order to get rendered. I am totally surprised as to why isn't there a direct support for html or is there one??
Thanks!
One obvious option is to simply rename your HTML files from foo.html to _foo.gsp and then use <render template="foo">. However this is so obvious that I'm sure you've already thought of it.
If you simply want to render a HTML file from within a controller you can use the text parameter of the render controller method
def htmlContent = new File('/bar/foo.html').text
render text: htmlContent, contentType:"text/html", encoding:"UTF-8"
If you want to do the same thing from within a .gsp, you could write a tag. Something like the following (untested) should work:
import org.springframework.web.context.request.RequestContextHolder
class HtmlTagLib {
static namespace = 'html'
def render = {attrs ->
def filePath = attrs.file
if (!file) {
throwTagError("'file' attribute must be provided")
}
def htmlContent = new File(filePath).text
out << htmlContent
}
}
You can call this tag from a GSP using
<html:render file="/bar/foo.html"/>
What is it you are trying to accomplish?
Render html from a controller?
In that case, all you should have to do is redirect the user to file from your control.
redirect(uri:"/html/my.html")
Use html-files instead of gsp template-files?
Thing is, Grails is a "Convention over Configuration"-platform and that means you will have to do some things "the Grails way". The files needs the _ and the .gsp but the name can be whatever you like even if it's easier when you use the same name as the controller. What you gain from doing that is the knowledge that every developer that knows grails and comes into your project will understand how things are tied together and that will help them get started quickly.
Little bit fixed the Don's example, works fine for me
import org.apache.commons.io.IOUtils
class HtmlTagLib {
static namespace = 'html'
def render = {attrs ->
def filePath = attrs.file
if (!filePath) {
throwTagError("'file' attribute must be provided")
}
IOUtils.copy(request.servletContext.getResourceAsStream(filePath), out);
}
}
I wanted to write static html/ajax pages hosted in grails app (v2.4.4), but use the controller for the url rewrite. I was able to accomplish this by moving the file to web-app/ (for ease of reference), and simply use the render() method with 'file' and 'contentType' params, such as:
// My controller action
def tmp() {
render file: 'web-app/tmp.html', contentType: 'text/html'
}
Note: I only tried this using run-app, and haven't packaged a war and deployed to tomcat, yet.

Closure include = { attr ->
out << Holders.getServletContext().getResource(attr.file).getContent();
}
It is relative to the web-app folder of your grails main application
I was able to use #momo's approach to allow inclusion of external files for grails rendering plugin, where network paths would get botched in higher environments - mine ended up like:
def includeFile = { attr ->
URL resource = Holders.getServletContext().getResource(attr.file)
InputStream content = resource.getContent()
String text = content?.text
log.info "includeFile($attr) - resource: $resource, content.text.size(): ${text?.size()}"
out << text
}
