Thanks in advance.
I have few status codes coming from database. Example 200, 205, etc.
In my language file, I have strings like -
VA_PRODCODE_200=Valid Product
VA_PRODCODE_205=Limited Edition Product
From ftl, I am trying translate the strings as below.
${"VA_PRODCODE_" + productstatus.productStatusCode}
where productstatus.productStatusCode is coming from database and have values like 200, 205
But the result is always coming as:
VA_PRODCODE_200
VA_PRODCODE_205
Can anyone tell me how to do this translation.
Thanks

Assuming the variable is in the data-model, like this:
${.data['VA_PRODCODE_' + productstatus.productStatusCode?c]}
?c is there to prevent localized number formatting, which can do things like adding thousand separators. (You could also use .vars, which works both for locals and data-model variables.)

Sorry, I am just learning how to use Rails.
I've got a simple .txt file asset which I would like to pull random Strings from to display on my landing page.
Is there an easy way in Rails to do this?
Assuming each string is in a separate line, you can do this:
strings = File.readlines('path/to/file.txt')
Then, to get a random string use sample, like this:
strings.sample
If you wan't more than one random string, just use sample with an argument, for example:
strings.sample(3)
This will return an array with 3 random lines from strings array.
Finally, you can do all in one line, for example, try this in the controller:
#string = File.readlines('path/to/file.txt').sample
And you will have #string available to use in the view.
So you are not giving me much. but I am going to assume that you want to get 1 line of a text file.
This is how I would do it
File.readlines("my/file/path.txt").sample
I hope that get you started :)
I am just starting a very basic program in Grails (never used it before, but it seems to be very useful).
What I have so far is:
in X.groovy,
a String named parameters, with constraint of maximum length 50000 and a couple other strings and dates, etc.
in XController.groovy,
static scaffold = X;
It displays the scaffold UI (very handy!), and I can add parameter strings and the other objects associated with it.
My problem is that the parameters string is a long string with formatting that is pasted in by the user. When it is displayed on the browser, however, it does not retain any carriage returns.
What is the best way to go about this? I'm a very beginner at Grails and still have lots and lots of learning to do on this account. Thanks.
The problem is that the string is being displayed using HTML which doesn't parse \n into a new line by default. You need to wrap the text in <pre> (see: http://www.w3schools.com/tags/tag_pre.asp) or replace the \n with <br/> tags to display it correctly to the user.
I'm using sfWidgetFormDoctrineChoice to get a list of languages from a MySql database. The list is in spanish language. All languages with special characters like for ex. Árabe looks OK (it got the tilde), but I'm getting the wrong representation (A!rabe) using the widget.
How can I resolve this?
Thanks in advance.
This is probably an encoding problem: verify that the list of languages registered in your database has the same encoding than the page where you display the widget.
But why don't you use the sfWidgetFormI18nChoiceLanguage widget ?
I am getting text from a feed that has alot of characters like:
Insignia™ 2.0 Stereo Computer Speaker System (2-Piece) - Black
4th-Generation Apple® iPod® touch
Is there an easy way to get rid of these, or do I have to anticipate which characters I want to delete and use the delete method to remove them? Also, when I try to remove
&
with
str.delete("&")
It leaves behind "amp;" Is there a better way to delete this type of character? Do I need to re-encode the text?
String#delete is certainly not what you want, as it works on characters, not the string as a whole.
Try
str.gsub /&/, ""
You may also want to try replacing the & with a literal ampersand, such as:
str.gsub /&/, "&"
If this is closer to what you really want, you may get the best results unescaping the HTML string. If so try this:
CGI::unescapeHTML(str)
Details of the unescapeHTML method are here.
If you are getting data from a 'feed', aka RSS XML, then you should be using an XML parser like Nokogiri to process the XML. This will automatically unescape HTML entities and allow you to get the proper string representation directly.
For removing try to use gsub method, something like this:
text = "foo&bar"
text.gsub /\b&\b/, "" #=> foobar
does anyone knows a file format for configuration files easy to read by humans? I want to have something like tag = value where value may be:
String
Number(int or float)
Boolean(true/false)
Array(of String values, Number values, Boolean values)
Another structure(it will be more clear what I mean in the fallowing example)
Now I use something like this:
IntTag=1
FloatTag=1.1
StringTag="a string"
BoolTag=true
ArrayTag1=[1 2 3]
ArrayTag2=[1.1 2.1 3.1]
ArrayTag3=["str1" "str2" "str3"]
StructTag=
{
NestedTag1=1
NestedTag2="str1"
}
and so on.
Parsing is easy but for large files I find it hard to read/edit in text editors. I don't like xml for the same reason, it's hard to read. INI does not support nesting and I want to be able to nest tags. I also don't want a complicated format because I will use limited kind of values as I mentioned above.
Thanks for any help.
What about YAML ? It's easy to parse, nicely structured has wide programming language support. If you don't need the full feature set, you could also use JSON.
Try YAML - is (subjectively) easy to read, allows nesting, and is relatively simple to parse.
