Qute and dynamic parameter

[jems....@gmail.com]

Hi,

I have this case where i have this extension called "field"

public class FieldTemplateExtension {
  static final String FIELD = "field";

  /**
   * Can be called like this {field_name:email}.
   *
   * @see FieldName
   * @param propertyName the field enum name
   * @return the field name
   */
  @TemplateExtension(namespace = FIELD, matchName = ANY)
  static Object getConfigProperty(String propertyName) {
    return FieldName.valueOf(propertyName.toUpperCase()).toString();
  }
}

The idea behind this is that i keep an enum of field names that i use to name form fields instead of using hard coded values that can be hard to change after.

So on the backend side i use this enum for instance to retrieve a parameter value that has been posted by the user and on the front side in Qute i use them in my html templates to give a name to an input field for instance

<input type="email" name="{field.email}" />

This works correctly but i want to be able to do also is to be able to also inject some parameters and be able to keep the same logic to test for their value/existance without using a hard coded parameter name in Qute template

I tried this

{#let activated=field:activated}
...
{/let}

But the issue when doing this is that field:activated will be translated to the parameter name and that's it where in my case i want to also retrieve its value if its defined using this enum. Is this possible ? is there another approach, a cleaner one maybe ?

Thank you

Regards,

I'm not quite sure I fully understand your question but you might define
you template extension method like this:

@TemplateExtension(namespace = FIELD)
static Object get(String propertyName) {
return FieldName.valueOf(propertyName.toUpperCase()).toString();
}

And then in the template use: {field:get(nameOfTheField)}.

Note that "get" is derived from the method name by default. And the
"nameOfTheField" is evaluated first and then passed to the template
extension method as the "propertyName" argument.

No what im trying to do is the following

In my controller i do this

Map<String, Object> templateData = new HashMap<>();
templateData.put(FieldName.ACTIVATED, true);
template.data(templateData)

But then in my Qute template i want basically read what's inside the activated parameter but using the enum to access the value

If i do this the check param will be set the enum string

{#let check=field:activated}
...
{/let}

But what i want is to retrieve the value of that parameter, in this case i want check param to contain true, so i can use it later on.

I hope it's clearer. Thank you for your help

Ok, so you'd like to use the enum constant as a key in the map.

In that case, something like this should work:

template.data("fields", templateData);

and then...

{#let check=fields.get(field:activated)}
...
{/let}

NOTE: In this case, it's better to use a specific name ("fields") for
the data map.
