Is there a way to change a subvariable within a hash or a container in a FreeMarker template? For example, suppose I had:
{"name":"Bob", "city":"Detroit", "state":"OH"}
and I want to change the state to "MI". How would I go about doing that? I know about the assign tag, but the documentation says "Note that only top-level variables can be created/replaced". I am unsure as to whether this means subvariables can't be replaced with the assign tag, or subvariables can't be replaced by any means.
I figured out a simple way to do it:
<#assign hash = hash + {"state":"MI"}>

I am new to freemarker and trying to extract list of value defined within bracket. Example below.. I would like to list values from () so can use it towards assign fucntion.. Couldn't get regex function to work correctly.. Can someone advice?
<alternative-id provider="abc.com" level="episode" description="CHICAGO GO (Sign) (primary) Ep 514">12345678</alternative-id>
<alternative-id provider="abc.com" level="episode" description="NewYork Show (primary) Ep 514">14561234</alternative-id>
<#if model["alternative-id[description=text(\((.*?)\))]"][0]?has_content >
tried regex (((.*?))) to extract the value but don't think freemarker support this. As i am very new to freemarker i am not sure if this is even allowed..
In my problem I search for elements that have an example structure like:
<ngc-product-card ng-reflect-signup-type="comprehensive">
Since the elements may have the comprehensive value stored in another attribute, say:
<new-ngc-product-card data-label="comprehensive signup">
hence I would like to use a wildcard-attribute-name search and also apply the contains() function like:
//*[contains(#*,"comprehensive")]
which doesn't work
What does work is
//*[#*="comprehensive"]
Is there any way to use both '#*' and 'contains()' ?
This should do.
//*[#*[contains(., "comprehensive")]]
I ran into an odd issue when trying to modify a chef recipe. I have an attribute that contains a large hash of hashes. For each of those sub-hashes, I wanted to add a new key/value to a 'tags' hash within. In my recipe, I create a 'tags' local variable for each of those large hashes and assign the tags hash to that local variable.
I wanted to add a modification to the tags hash, but the modification had to be done at compile time since the value was dependent on a value stored in an input json. My first attempt was to do this:
tags = node['attribute']['tags']
tags['new_key'] = json_value
However, this resulted in a spec error that indicated I should use node.default, or the equivalent attribute assignment function. So I tried that:
tags = node['attribute']['tags']
node.normal['attribute']['tags']['new_key'] = json_value
While I did not have a spec error, the new key/value was not sticking.
At this point I reached my "throw stuff at a wall" phase and used the hash.merge function, which I used to think was functionally identical to hash['new_key'] for a single key/value pair addition:
tags = node['attribute']['tags']
tags.merge({ 'new_key' => 'json_value' })
This ultimately worked, but I do not understand why. What functional difference is there between the two methods that causes one to be seen as a modification of the original chef attribute, but not the other?
The issue is you can't use node['foo'] like that. That accesses the merged view of all attribute levels. If you then want to set things, it wouldn't know where to put them. So you need to lead off by tell it where to put the data:
tags = node.normal['attribute']['tags']
tags['new_key'] = json_value
Or just:
node.normal['attribute']['tags']['new_key'] = json_value
Beware of setting things at the normal level though, it is not reset at the start of each run which is probably what you want here, but it does mean that even if you remove the recipe code doing the set, the value will still be in place on any node that already ran it. If you want to actually remove things, you have to do it explicitly.
When setting repeated content in a section in Orbeon each control is repeated and the their names are the same. How do I access the the control from the first, second...etc instance of a control from each iterated section? I'm thinking along the lines of $control-name[instance#] or something similair.
The following works, given this form:
$name[2]: return the second value
string-join($name, ', '): join all values with commas
count($name): return the number of values
See also the relevant documentation.
To access this value in "bind" section, you can use a relative path , like ../name=''.
TO access this value in "body" section, then you can use context()/../name.
If you are trying to make anything different, be more specific and this answer can be edited to be according to what you want.
Let me start with I'm not a programmer by trade, but I'm learning the best I can. I'm trying to build a template to take the result of one FreeMarker interpolation result and use that as a variable for another. I hope I'm using the terms correctly.
For example, I want the result of (entity.customer.organization.name) to be used in:
${blurb["organizationXXXAttire"]!}
Where XXX is the result of (entity.customer.organization.name)
If it was just a blurb with out a variable company name it would look like:
${blurb["organizationCompanyAttire"]!}
I thought the following would work but it did not:
<#assign organization = (entity.customer.organization.name)>
${blurb["organization<#organization?interpret>Attire"]!}
Thanks in advance for any suggestions.
It's simply ${blurb["organization${entity.customer.organization.name}Attire"]!}.
?interpret is only needed if you have a string that contains a piece of template. Besides you can't call directives (<#...>, <#...>) inside an expression.
