difference between template.Execute and template.ExecuteTemplate()

[mir.an...@gmail.com]

Hi,

func (t *Template) Execute(wr io.Writer, data interface{}) error

func (t *Template) ExecuteTemplate(wr io.Writer, name string, data interface{}) error

Can someone tell me the difference between the above two functions ?

In case of second one, in the name string parameter, you need to specify the template name.

Hello
It seems that the relevant part of the doc is here :

Each template is named by a string specified when it is created. Also, each template is associated with zero or more other templates that it may invoke by name; such associations are transitive and form a name space of templates.

So, a *Template always has a name, whether explicitly set by user calling New(name), or automatically assigned by ParseFiles or ParseGlob. Also, you can have nested template definitions, which create additional template names.
At first I thought a *Template would "contain" one or more named "things", but the doc suggests that the right terminology would be "a template may have associated templates".

I wrote this example showing that Execute / ExecuteTemplate give different results, for different names invoked :
Execute
ExecuteTemplate "phase1"
ExecuteTemplate "phase2"
ExecuteTemplate "phase3"
ExecuteTemplate "wrongName"

Cheers
