Using Actuate eReport Designer Professional 9 SErvice Pack 3 Fix 2
I am attempting to set a text control's ValueExp property to display a string consisting of a division result concatenated with some static text. I want the division result to display as an integer if there is no remainder. Otherwise, I want only 1 decimal place.
There will be conditional logic involved, but I will be able to handle that. What I am really looking for is, using the Expression Builder only, can I format numbers. For example, how would I get the expression, 5/3 & " text" to display 1.7 text? This guess,
round(5/3, 1) & " text"
threw errors for "illegal variable use (round)" and "operator not found for these types"
From Dominique's answer, this effort:
BirtMath.round(5/3, 1)
resulted in an illegal variable use on BirtMath.
Try this:
BirtMath.round(5/3, 1) + " text"
(tested on BIRT Eclipse designer, this should be the same with actuate professional designer)
What finally got the job done was:
Format(5/3, "##.#") & " text"
Dominique's answer refers to BIRT, which is a completely different technology/product.
If you want to display a numeric value with special formatting, a Text Control is not the best choice here. Instead, you should use a numeric control of the appropriate type (for example, a Double Control) and either override the GetText() method of that control to handle the display formatting or use Conditional Formatting. The reason this is a better solution is that data search and export will not work properly with a Text Control.
Note that you can use a format pattern like this: "#,##0 \T\e\x\t" instead of concatenating the string; this technique is needed when you are using Conditional Formatting.
Personally, I would prefer you to use Conditional Formatting, because I put a lot of effort into designing that feature of e.Reports, and I'd like to see more people using it. :) But overriding GetText() is probably easier in your specific situation, due to the need to do more complex string manipulation to eliminate the trailing decimals.
I want to add that with BIRT, you can also format the text in a more 'graphic' way, without the need for SQL ... in case it is useful to someone ...
Select the Object - Properties - Format Number - You choose the Format
there is variety for each case and in addition to adding the custom format.
Of course, it is everyone's decision to how format the text, and it is always good to know how it is done in different ways!

I have several processes with almost same flow like "Get some parameters, extract data from database according to them and upload them to target". The parameters vary slightly across processes as well as targets but only a bit. Most of the process is the same. I would like to extract those differences to parameter-context and dynamically load them. My idea is to have parameters defined following way and then using them.
So core of question is:
How to dynamically choose which parameter group load and use?
Having several parameter contexts with same-named/different-valued parameters and dynamically switching them would be probably the best, but it is not possible as far as I know.
Also duplicating flows is out-of-the-table. Any error correction would be spread out over several places and maintenance would be a nightmare.
Moreover, I know I can do it like "In GenetrateFlowFile for process A set value1=#{A_value1} and in GenetrateFlowFile for process B set value1=#{B_value1}. But this is tedious, error-prone and scales kinda bad. Not speaking of situation when I can have dozens of parameters and several processes. Also it is a kind of hardcoding, not configuring...
I was hoping for something like defining group=A and then using it like value1=#{ ${ group:append('_value1') } } but this does not work - it is evaluated as parameter literally named ${ group:append('_value1') }.
TL;DR: Use evaluateELString().
The actual solution is to set in GenetrateFlowFile processor group=A and in next UpdateAttribute processor set the following:
value1=${ group:prepend('hash{ '):append('_value1 }'):replace('hash', '#'):evaluateELString() }
The magic being done here is "Take value of group slap around it #{ and _value1 } to make it valid NiFi Expression Language statement and then evaluate it." (Notice - the word hash and function replace is there since I didn´t manage to escape the # char right before {.)
If you would like to have your value1 at the beginning of the statement then you can use following code. The result is same, it is easier to use (often-changed value value1 is at the beginning of the statement) and is less readable "what is really going on?"-wise.
value1=${ literal('value1'):prepend('_'):prepend(${ group }):prepend('hash{ '):append(' }'):replace('hash', '#'):evaluateELString() }
I'm sort of new to Web2py. I have a system that's working just fine, but I want to make an improvement regarding visualization. There's a couple of fields that use numbers (defined as double in their respective define_table methods) to represent currency, but I want them to also show with a separator for thousands, such as 183,403,293.34. I checked some documentation, but I couldn't find a direct way to handle this form of customization, though I could be missing something.
Any suggestions regarding this? Cheers!
First, if representing currency, you should use the decimal field type rather than double (some calculations using double values may yield incorrect results due to the use of floating point representations internally). However, if using SQLite, there is no distinction between decimal and double, so in that case, you might want to multiply all values by 100 and instead store integers.
In any case, to display a given numeric value with thousands separators in Python, you can do:
'{:,}'.format(myvalue)
For more details, see https://stackoverflow.com/a/10742904/440323 and https://stackoverflow.com/a/21208495/440323.
If you are using the values via web2py functionality that makes use of the field's represent function (e.g., the grid or the .render() method), you can define a custom represent function, such as:
Field('amount', 'decimal(12, 2)',
represent=lambda v, r: '{:,}'.format(v) if v is not None else '')
You could use the Python function of the locale module:
{{= locale.format ('%. 2f', your_value, grouping = True)}}
Im trying to build a email template with Freemarker/Clickdimensions plugin in CRM 2013. I have a "Date only" field on an entity which for example contains the date 2017-04-17. I want this date to show as the following: Monday 17 april.
This is done with Freemarker and I have tried the following:
<#assign x = Recipient.field_booking.field_scheduleddate?time>
${x?string.full}
This doesnt seem to work. Im not getting any result at all, just an empty line.
Does anyone know what could be wrong?
I will assume that field_scheduleddate is a string (not a java.util.Date).
At ?time FreeMarker should throw and exception saying something like that the string doesn't follow the expected pattern. I suspect the framework you are using catches and suppresses that exception (which makes using FreeMarker much much harder). Check the logs, maybe it's there.
You want to deal with a date-only value there, hence you should use ?date, as ?time is for time-only values. Also, field_scheduleddate apparently uses ISO 8601 format, so unless the date_format configuration setting is set to ISO, you will have to use ?date.iso (supported since FreeMarker 2.3.21).
As of printing the date, ?string.full should work, but usually you should set date_format globally to the format you prefer, and then you can simply write ${x}.
(Also note that #assign is unnecessary above, as you can put arbitrarily complex expression inside ${}.)
My current issue is to find HTML-Tags inside of property values. I thought it would be easy to search with a query like /jcr:root/content/xgermany//*[jcr:contains(., '<strong>')] order by #jcr:score
It looks like there is a problem with the chars < and > because this query finds everything which has strong in it's property. It finds <strong>Some Text</strong> but also This is a strong man.
Also the Query Builder API didn't helped me.
Is there a possibility to solve it with a XPath or SQL Query or do I have to iterate through the whole content?
I don't fully understand why it finds This is a strong man as a result for '<strong>', but it sounds like the unexpected behavior comes from the "simple search-engine syntax" for the second argument to jcr:contains(). Apparently the < > are just being ignored as "meaningless" punctuation.
You could try quoting the search term:
/jcr:root/content/xgermany//*[jcr:contains(., '"<strong>"')]
though you may have to tweak that if your whole XPath expression is enclosed in double quotes.
Of course this will not be very robust even if it works, since you're trying to find HTML elements by searching for fixed strings, instead of actually parsing the HTML.
If you have an specific jcr:primaryType and the targeted properties you can do something like this
select * from nt:unstructured where text like '%<strong>%'
I tested it , but you need to know the properties you are intererested in.
This is jcr-sql syntax
Start using predicates like a champ this way all of this will make sense to you!
HTML Encode <strong>
HTML Decimal <strong>
Query builder is your friend:
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%3Cstrong%3E%25
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have a go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%26lt%3Bstrong%26gt%3B%25
XPath:
/jcr:root/content/geometrixx//element(*, nt:unstructured)
[
jcr:like(#text, '%<strong>%')
]
SQL2 (already covered... NASTY YUK..)
SELECT * FROM [nt:unstructured] AS s WHERE ISDESCENDANTNODE([/content/geometrixx]) and text like '%<strong>%'
Although I'm sure it's entirely possible with a string of predicates, it's possibly heading down the wrong route. Ideally it would be better to parse the HTML when it is stored or published.
The required information would be stored on simple properties on the node in question. The query will then be a lot simpler with just a property = value query, than lots of overly complex query syntax.
It will probably be faster too.
So if you read in your HTML with something like HTMLClient and then parse it with a OSGI service, that can accurately save these properties for you. Every time the HTML is changed the process would update these properties as necessary. Just some thoughts if your SQL is getting too much.
I have a very standard binding set up in android on a UITextView
local:MvxBind="Text Quantity"
Where Quantity is an int property.
If I enter 123 say, that gets assigned and the setter is called. As I delete that text, 123 -> 12 -> 1 -> empty string, the setter is called for each number but not for the empty string infact the following exception occurs:
MvxBind:Error: 48.84 SetValue failed with exception - FormatException: Input string was not in the correct format
Is there a way of automatically converting the empty string value to 0 in the binding? Will I need a value converter for this? Is this in fact a bug?
Thanks in advance.
This area has been discussed recently in https://github.com/slodge/MvvmCross/issues/350 with some nullable additions in https://github.com/slodge/MvvmCross/issues/373 - people are welcome to contribute their opinions (and/or code) there.
The current 'status quo' is that MvvmCross will parse and represent valid decimal numbers. However, if the number isn't valid - eg if it's string.Empty or a set of non-numeric characters - then MvvmCross won't interpret these as zero (should "" be zero? should "asdf" be zero? should "123.456.7" be zero? should "1234asd" be zero? perhaps all of these should actually be NaN?).
If people need specific behaviour then it's easy for them to implement this behaviour - e.g. using a custom control (subclassed UITextField), using a value converter, using a custom binding (or overriding the default binding), using a string property on the viewModel, etc.
My personal opinion is that this topic really comes under the Validation heading. In general, MvvmCross doesn't provide many hooks for Validation at present. It's been proposed for a long time - https://github.com/slodge/MvvmCross/issues/133 - but no-one has shown much interest. There are some simple validation samples in the WithErrors demo within https://github.com/slodge/MvvmCross-Tutorials/tree/master/ApiExamples. Within the apps I've written we've generally written and sub-classed UI controls to help reduce the need for validation - and in general we've tried to avoid the need for as much text input as we can (users don't like seem to like using keypads on phones)
