I probably wasn't explaining it very well....
I am wanting a column within my table plus to display an icon - I have
a method which retrieves an icon from a specific directory and shows
in a standard page view, but when this method is called
in the table plus, I just get a display of the directory.... e.g
<table-plus with="&@version" fields="this, created_at, getIcon " >
(the getIcon column is the method to grab the icon from the directory)
the method just concatenates the appropriate filename and directory -
in the view page -this is just called as <img src="&this.getIcon" />
which displays the icon - but when I call the method in the <table-
plus> I just get /directory/icons/icon.png displayed in the
table,
am I just doing something that is not possible within the <table-
plus>?
Here's one way to do it:
<table-plus with="&@version" fields="this, created_at, get_icon">
<get-icon-heading:></get-icon-heading:>
<get-icon-view:>
<img src="#{this}" />
</get-icon-view:>
</table-plus>
I took the liberty of conforming the get_icon method to Rails
conventions (underscore rather than camelCase).
