Handling CSRF tokens with my own forms

[vitr]

Steps to Reproduce the Problem

Follow 'How Do I Handle CSRF Tokens If I Use My Own Form?' on the docs page https://gobuffalo.io/en/docs/forms

template.HTML("<input name=\"authenticity_token\" value=\"<%= authenticity_token %>\" type=\"hidden\">")

Expected Behavior

The template should render to value of actual token, the same token as in the header

<meta name="csrf-token" content="<%= authenticity_token %>" />

renders to

<meta name="csrf-token" content="Lc0YrNyM3EkqZgzui1JGStnHbwvfVNB8Iw3O7TMJolHh9ckUsUMBZgDkYolbOybUyJVxrh51O4Y9GkHMOaKqkg==" />

Actual Behavior

In fact, the code from the docs renders to

<input name="authenticity_token" value="<%= authenticity_token %>" type="hidden">

See the variable authenticity_token hasn't been translated into actual value. I'd appreciate if either documentation or code will be corrected. Thank you.

p.s. I think here is the related issue https://github.com/mikaelm1/Blog-App-Buffalo/issues/4

[mycroftsk]

Code in documentation is probably for older versions of Buffalo.

What works for me:

// render.go

Helpers: render.Helpers {
    "csrf": func(helper plush.HelperContext) template.HTML {
        t, _ := helper.Render("<input name=\"authenticity_token\" value=\"<%= authenticity_token %>\" type=\"hidden\">")
        return template.HTML(t)
    },
},
