To support Mandrill merge vars when sending templates call AddGlobalMergeVars about mandrill HOT 3 CLOSED

I’m not sure I’ve understood this issue. You can already add both merge variables (global ones though, not per recipient) and template content data. What exact change are you expecting for this issue?

BTW, thanks for the kind words.

Thanks for the quick reply.
I have a template in Mandrill with the following merge var and dynamic section.

Hello *|NAME|* also known as <span mc:edit="NAME"></span>

Example in README

tmplName := "hello-world"
email := "[email protected]"
name := "mostafah"
data := map[string]string{("NAME": name})
mandrill.NewMessageTo(email, name).SendTemplate(tmplName, data, true)

This will send and email with the content

Hello also known as mostafah

If you add the AddGlobalMergeVars, it will format the data for Merge Vars as well

// Same variable declaration as above but do the following
msg := mandrill.NewMessageTo(email, name)
msg.AddGlobalMergeVars(data)
result, err := msg.SendTemplate(tmplName, data, true)

Now the email will be

Hello mostafah also known as mostafah

I believe the issue is that SendTemplate just sends template data...

data.TemplateName = tmpl
data.TemplateConent = mapToVars(content)

While AddGlobalMegeVars adds the data to the the msg

msg.GlobalMergeVars = append(msg.GlobalMergeVars, mapToVars(data)...)

Thanks.

Well, that’s by design. Mandrill accepts two kinds of data: merge variables and template data. You can send both with this package, but they are separate things. I can’t send what is passed for template data as merge variables too. That takes the ability to set different merge variables from people.

Mandrill’s API provides two different arrays for these, and the library does that too.

To tell it again in other words, Mandrill’s Send-Template function takes these (and other things) as JSON input:

{
    "template_name": "foo",
    "template_content": [
        {"name": "varname", "content": "value"},
        {"name": "varname", "content": "value"},
        …
    ],
    "message": {
        "global_merge_vars": [
            {"name": "varname", "content": "value"},
            {"name": "varname", "content": "value"},
            …
        ],
    }
}

You can set the first one with function SendTemplate and the second one with function AddGlobalMergeVars. Merging the two doesn’t make sense for other users.
