I'm having trouble while trying to assign value to a variable using Freemarker.
<#if size??>
<#assign num=size?number>
<#if (num>0)>
<#list 0..num-1 as i>
<#if .vars['abc'+i?c] = "test">
<#assign .vars['abc'+i?c] = .vars['abc'+i?c]?replace("test","Test")>
</#if>
</#list>
</#if>
This is the error message: Encountered ".", but was expecting one of:
STRING_LITERAL
RAW_STRING
ID
Can anyone help me with this?
Thank you.
You can only write top-level variables in a FreeMarker template. Also you can't assign to a variable with dynamically constructed name, except with an ?interpret hack: <#"<#assign abc${i?c} = abc${i?c}?reaplce('test', "Test")>"?interpret />. Obviously that's horrid... BTW, what's the use case here? Why do you need to assign to dynamically constructed variable names?
<#assign reasonValue="xxx.ftl">
and I call it like:
<#include "${reasonValue}">
and I get output like:
Rejected - Something
how can I now use split on this ouput because I would like to get just Something as output
I tried:
<#list "${reasonValue}"?split("-") as sValue>
${sValue}
</#list>
but problem is that instead of real value i get name of ftl file...
Assign output of include to some variable and then use split on this variable.
<#assign xx>
<#include reasonValue>
</#assign>
<#list xx?split("-") as sValue>
${sValue}
</#list>
If you need to show only part of the string after "-" then use substring and index_of.
${xx?substring(xx?index_of("-") + 2)}
How to handle null values in Freemarker? I get some exceptions in the template when null values are present in data.
Starting from freemarker 2.3.7, you can use this syntax :
${(object.attribute)!}
or, if you want display a default text when the attribute is null :
${(object.attribute)!"default text"}
You can use the ?? test operator:
This checks if the attribute of the object is not null:
<#if object.attribute??></#if>
This checks if object or attribute is not null:
<#if (object.attribute)??></#if>
Source: FreeMarker Manual
I think it works the other way
<#if object.attribute??>
Do whatever you want....
</#if>
If object.attribute is NOT NULL, then the content will be printed.
Use ?? operator at the end of your <#if> statement.
This example demonstrates how to handle null values for two lists in a Freemaker template.
List of cars:
<#if cars??>
<#list cars as car>${car.owner};</#list>
</#if>
List of motocycles:
<#if motocycles??>
<#list motocycles as motocycle>${motocycle.owner};</#list>
</#if>
I would like to add more context if you have issues and this is what I have tried.
<#if Recipient.account_type?has_content>
… (executes if variable exists)
<#else>
… (executes if variable does not exist)
</#if>
This is more like Javascript IF and ELSE concept where we want to check whether this value or another chaining through required logic.

Other reference:
Scenario: Customer has ID and name combined like 13242 Harish, so where our stakeholder need the only name, so I have tried this ${record.entity?keep_after(" ")} and it did work, however, it can only work when you have space, but when a customer doesn't have space and one name, I had to do some IF ELSE condition to check Null value.
Use:
${(user.isSuperman!false)?c}
It will work when "isSuperman" is null and when have boolean value
What we want:
For "null" we want to output 'false'
For boolean value and want to output value ('true' or 'false')
What we know:
boolean need to convert to string by using "?c" see Built-ins for booleans
but null we cannot convert to string and we need to use "!" see Handling missing values
I am using freemarker to generate a Java class. I am stuck to convert a first character of a string to lower case.
Following is what i tryed but no luck :(
<#function methodName attName >
<#if attName?length > 1 >
<#if attrName(0)?matches([a-z])>
<#return attName>
</#if>
</#if>
</#function>
Thanks.
Try uncap_first:
${"Test"?uncap_first} yields test
Code:
<#spring.formInput 'myForm.spouseEmail' 'id="spouseEmail" class="text"'/>
<#spring.showErrors ', ' 'error'/>
Output:
<span class="error">not a well-formed email address</span>
What I want:
<div class="error">not a well-formed email address</div>
#Mike: it seems you have troubles understanding the nature of macros. They are already-written freemarker script to make your life easier. You can always write a customed one.
Some people think it obvious, but I myself find that it's not easy to know how to view the spring-freemarker macros source code. You can navigate to package org/springframework/spring-webmvc-3.0.5.jar/org/springframework/web/servlet/view/freemarker/spring.ftl in Eclipse's "Referenced Libraries".
Here's the macro "showErrors" gotten from "spring.ftl":
<#macro showErrors separator classOrStyle="">
<#list status.errorMessages as error>
<#if classOrStyle == "">
<b>${error}</b>
<#else>
<#if classOrStyle?index_of(":") == -1><#assign attr="class"><#else><#assign attr="style"></#if>
<span ${attr}="${classOrStyle}">${error}</span>
</#if>
<#if error_has_next>${separator}</#if>
</#list>
</#macro>
To achieve your goal, it's very simple: just write a custom macro which is exactly like the code above, replace span by div
No, but you can easily write your own macro to do whatever you want. Get your inspiration from spring.showErrors itself.
